Question 480

An architect proposes the following step: configure active-active stateless Tier-0 with suitable ECMP external routes. The context is: The enterprise wants throughput and failover across multiple external Edge paths and does not require stateful translation at Tier-0. What is the strongest technical reason for that decision?

  1. Retained logs allow investigators to sequence transient faults after live status has recovered.
  2. Traceflow can expose logical path decisions and drops across the distributed and service-routing path.
  3. Modern NSX supports stateful services on eligible active-active Tier-0 designs, subject to documented feature limitations.
  4. ECMP distributes eligible flows across multiple live next hops and allows path withdrawal on failure.

Explanation

Correct Answer

D:

ECMP distributes eligible flows across multiple live next hops and allows path withdrawal on failure. This explains the proposed decision in the current active-active stateless gateway situation. The intended outcome is to use equal-cost route sharing in a supported gateway mode, and verification would show: Several independent flows use different eligible paths and continue after one peer is removed.

Incorrect Answers

A:

This statement can describe a central log correlation problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to reconstruct time-stamped NSX events after the fact; here the relevant requirement is to use equal-cost route sharing in a supported gateway mode.

B:

This statement can describe a traceflow path problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to locate the NSX forwarding or policy decision affecting this flow; here the relevant requirement is to use equal-cost route sharing in a supported gateway mode.

C:

This statement can describe a stateful active-active support problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to select a valid HA architecture for required stateful services; here the relevant requirement is to use equal-cost route sharing in a supported gateway mode.

Question 481

A reviewer must validate the intended NSX outcome. Situation: External auditors require six-month retention of NSX operational logs, but local retention is shorter. Which result most directly demonstrates that the team can preserve searchable NSX evidence for required periods?

  1. Known NSX test events appear on the collector and remain retrievable under policy.
  2. Valid outbound requests and their replies pass; unmatched inbound connection attempts are denied.
  3. Cluster/service status and API responsiveness recover without unrelated segment changes.
  4. A valid recent backup is present in the planned repository and restore prerequisites are documented.

Explanation

Correct Answer

A:

Known NSX test events appear on the collector and remain retrievable under policy. This observation validates the specified syslog destination outcome. Remote log collectors can hold events beyond local appliance rotation while preserving timestamps.

Incorrect Answers

B:

This would validate stateful gateway policy rather than the needed syslog destination result. Stateful inspection distinguishes traffic belonging to established sessions from unauthorized new attempts. For the present case, the evidence must show that the team can preserve searchable NSX evidence for required periods.

C:

This would validate manager service validation rather than the needed syslog destination result. API unavailability can arise from Manager health independently of data-plane application paths. For the present case, the evidence must show that the team can preserve searchable NSX evidence for required periods.

D:

This would validate manager backup schedule rather than the needed syslog destination result. Reliable backups protect management and policy configuration when an upgrade or outage requires restoration. For the present case, the evidence must show that the team can preserve searchable NSX evidence for required periods.

Question 482

Two VCF locations use overlapping infrastructure endpoint ranges that would break stretched network routing. The engineering team needs to avoid conflicting transport and management addresses across site boundaries. What action best addresses the immediate requirement?

  1. standardize encrypted backup destinations and periodically test instance-specific restores
  2. plan nonoverlapping reachable manager, transport and remote TEP addressing
  3. enforce distributed firewall rules using workload group membership
  4. keep site-specific networking objects local and apply common Federation security where supported

Explanation

Correct Answer

B:

Overlapping infrastructure addresses create ambiguity in cross-site control and tunnel connectivity. The selected action, plan nonoverlapping reachable manager, transport and remote TEP addressing, directly supports the specified goal to avoid conflicting transport and management addresses across site boundaries. A useful confirmation is: Address inventory and reachability tests show unique manager and transport endpoint IPs at both sites.

Incorrect Answers

A:

Standardize encrypted backup destinations and periodically test instance-specific restores would address the separate case of backup consistency, where the objective is to recover each fleet networking control plane from documented backups. Backups must be associated with the correct management instance and verified for recovery usefulness. Here the requirement is instead to avoid conflicting transport and management addresses across site boundaries; that step does not directly satisfy it.

C:

Enforce distributed firewall rules using workload group membership would address the separate case of distributed microsegmentation, where the objective is to restrict inter-tier traffic without forcing all flows off-host. Host-level distributed firewalling reduces the need to route every VM flow through an appliance to apply policy. Here the requirement is instead to avoid conflicting transport and management addresses across site boundaries; that step does not directly satisfy it.

D:

Keep site-specific networking objects local and apply common Federation security where supported would address the separate case of site autonomy versus shared policies, where the objective is to combine global policy intent with local gateway configuration. Federation does not require every local routing choice to become a global object. Here the requirement is instead to avoid conflicting transport and management addresses across site boundaries; that step does not directly satisfy it.

Question 483

An architect proposes the following step: apply suitable prefix filtering or route-map policy to Tier-0 route export. The context is: A business requires only production application subnets to leave the Tier-0 BGP session. What is the strongest technical reason for that decision?

  1. Site-specific monitoring distinguishes local transport faults from global policy defects.
  2. Broadcom documents that a VRF gateway is not supported on an active-active stateful parent Tier-0.
  3. Outbound routing policy prevents accidental advertisement of private or management networks.
  4. Creating one logical router does not automatically configure every optional service on it.

Explanation

Correct Answer

C:

Outbound routing policy prevents accidental advertisement of private or management networks. This explains the proposed decision in the current bgp prefix filtering situation. The intended outcome is to limit external routing announcements to approved networks, and verification would show: An upstream table shows only the approved production prefixes from the gateway.

Incorrect Answers

A:

This statement can describe a multi-site comparison problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to compare per-site transport health under a shared management policy; here the relevant requirement is to limit external routing announcements to approved networks.

B:

This statement can describe a tier-0 stateful ha constraint problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to choose a supported combination of VRF and stateful HA features; here the relevant requirement is to limit external routing announcements to approved networks.

D:

This statement can describe a tier-1 gateway smoke test problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to validate routing, DHCP, DNS and NAT as separate configured capabilities; here the relevant requirement is to limit external routing announcements to approved networks.

Question 484

An architect proposes the following step: maintain healthy Local Manager and local transport/Edge infrastructure in each site. The context is: A regional site must retain local network forwarding during a temporary outage of its Global Manager connection. What is the strongest technical reason for that decision?

  1. Reliable name resolution and time synchronization support certificates, logs and service interoperability.
  2. Fleet-wide observability can correlate health and capacity without turning local NSX management into a packet forwarding tier.
  3. Global groups can match protected resources across sites while a central policy expresses common decisions.
  4. Global management coordination is separate from existing local data-plane forwarding and site health.

Explanation

Correct Answer

D:

Global management coordination is separate from existing local data-plane forwarding and site health. This explains the proposed decision in the current local survivability situation. The intended outcome is to keep site data-plane operations resilient to central management interruption, and verification would show: Existing permitted local workload traffic continues during a controlled loss of global management reachability.

Incorrect Answers

A:

This statement can describe a ntp and dns prerequisites problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to establish consistent fundamental management services; here the relevant requirement is to keep site data-plane operations resilient to central management interruption.

B:

This statement can describe a central visibility across instances problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to aggregate monitoring while retaining local control-plane ownership; here the relevant requirement is to keep site data-plane operations resilient to central management interruption.

C:

This statement can describe a global security objects problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to apply common multi-site security semantics; here the relevant requirement is to keep site data-plane operations resilient to central management interruption.

Question 485

Security wants to find exactly when a Tier-0 BGP session dropped during a long outage. The engineering team needs to correlate timestamped NSX gateway and neighbor events. What action best addresses the immediate requirement?

  1. query NSX logs in the configured central logging system
  2. prepare compatible Local Managers, deploy Global Manager and register the locations
  3. associate a supported DHCP server or relay configuration with the segment
  4. route alert definitions to an accountable owner and a documented escalation policy

Explanation

Correct Answer

A:

Time-ordered logs can show routing state changes and related process errors more precisely than an aggregate green/red health icon. The selected action, query NSX logs in the configured central logging system, directly supports the specified goal to correlate timestamped NSX gateway and neighbor events. A useful confirmation is: Log entries identify the BGP neighbor and time its state transitioned.

Incorrect Answers

B:

Prepare compatible Local Managers, deploy Global Manager and register the locations would address the separate case of manager deployment order, where the objective is to onboard the NSX site into a supported multi-location Federation. Federation requires a functioning global management layer connected to eligible local management instances. Here the requirement is instead to correlate timestamped NSX gateway and neighbor events; that step does not directly satisfy it.

C:

Associate a supported DHCP server or relay configuration with the segment would address the separate case of dhcp scope association, where the objective is to make the correct DHCP function available to segment members. DHCP clients require a valid service or relay path and usable address scope. Here the requirement is instead to correlate timestamped NSX gateway and neighbor events; that step does not directly satisfy it.

D:

Route alert definitions to an accountable owner and a documented escalation policy would address the separate case of monitoring alert ownership, where the objective is to make monitoring actionable by assigning response responsibility. Alert effectiveness depends on response workflow as well as the metric threshold. Here the requirement is instead to correlate timestamped NSX gateway and neighbor events; that step does not directly satisfy it.

Question 486

An architect proposes the following step: keep site-specific networking objects local and apply common Federation security where supported. The context is: A remote branch requires its own egress route while sharing enterprise security controls. What is the strongest technical reason for that decision?

  1. A stretched network does not automatically determine the best egress; gateway placement and route preferences control it.
  2. Federation does not require every local routing choice to become a global object.
  3. Tunnel headers add bytes beyond guest payload size, and a smaller fabric MTU can break large encapsulated frames.
  4. The distributed firewall evaluates relevant flows at the host data plane rather than relying on traffic crossing a physical perimeter.

Explanation

Correct Answer

B:

Federation does not require every local routing choice to become a global object. This explains the proposed decision in the current site autonomy versus shared policies situation. The intended outcome is to combine global policy intent with local gateway configuration, and verification would show: The branch uses its local external peer while the expected global controls are realized there.

Incorrect Answers

A:

This statement can describe a cross-site traffic steering problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to design predictable local north-south egress by site; here the relevant requirement is to combine global policy intent with local gateway configuration.

C:

This statement can describe a overlay mtu budget problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to accommodate tunnel overhead across the physical transport path; here the relevant requirement is to combine global policy intent with local gateway configuration.

D:

This statement can describe a distributed firewall enforcement problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to enforce security near workload virtual interfaces; here the relevant requirement is to combine global policy intent with local gateway configuration.

Question 487

Two departments assign the same subnet to routable segments in one shared routing context. The engineering team needs to avoid ambiguous route selection between workload segments. What action best addresses the immediate requirement?

  1. include the route's network in an allowed External IP Block and matching connection profile
  2. verify TEP interface and fabric MTUs against GENEVE overhead
  3. allocate distinct nonoverlapping IP subnets in the shared routing domain
  4. create a VLAN-backed NSX segment with the proper VLAN ID and switch uplink

Explanation

Correct Answer

C:

Overlapping directly connected networks in one route context can produce ambiguous traffic delivery. The selected action, allocate distinct nonoverlapping IP subnets in the shared routing domain, directly supports the specified goal to avoid ambiguous route selection between workload segments. A useful confirmation is: The Tier-1 route table shows unique network destinations for both segments.

Incorrect Answers

A:

Include the route's network in an allowed External IP Block and matching connection profile would address the separate case of vpc external ip block policy, where the objective is to permit the intended VPC external network through the provider's outbound advertisement controls. Outbound advertisement filters can suppress routes not covered by an approved External IP Block. Here the requirement is instead to avoid ambiguous route selection between workload segments; that step does not directly satisfy it.

B:

Verify TEP interface and fabric MTUs against GENEVE overhead would address the separate case of tunnel encapsulation test, where the objective is to ensure transport-node configuration matches physical MTU capacity. The host tunnel encapsulation adds bytes that the underlay must carry. Here the requirement is instead to avoid ambiguous route selection between workload segments; that step does not directly satisfy it.

D:

Create a VLAN-backed NSX segment with the proper VLAN ID and switch uplink would address the separate case of vlan segment creation, where the objective is to extend the designated physical L2 network to the virtual interface. VLAN-backed segments use physical tagged forwarding for integration with non-overlay devices. Here the requirement is instead to avoid ambiguous route selection between workload segments; that step does not directly satisfy it.

Question 488

Manager audit trails show inconsistent time ordering across nodes following a site outage. The engineering team needs to restore trustworthy event timelines and time-sensitive authentication. What action best addresses the immediate requirement?

  1. configure the intended VPC egress NAT or external connectivity capability
  2. create an eligible VLAN segment and connect the Edge external uplink to the correct fabric VLAN
  3. inspect Edge health metrics and log volume, then tune retention or collection policy
  4. repair NTP reachability and synchronization across NSX management components

Explanation

Correct Answer

D:

Time drift undermines log correlation and can affect certificate or authentication workflows. The selected action, repair NTP reachability and synchronization across NSX management components, directly supports the specified goal to restore trustworthy event timelines and time-sensitive authentication. A useful confirmation is: All affected nodes report synchronized clocks and new events sort correctly.

Incorrect Answers

A:

Configure the intended VPC egress NAT or external connectivity capability would address the separate case of vpc egress nat design, where the objective is to supply a supported outbound translation path for the tenant. Private-address VPC egress requires a deliberate routable path and translation if external peers cannot return to private space. Here the requirement is instead to restore trustworthy event timelines and time-sensitive authentication; that step does not directly satisfy it.

B:

Create an eligible VLAN segment and connect the Edge external uplink to the correct fabric VLAN would address the separate case of edge uplink segment, where the objective is to prepare the VLAN-backed Edge uplink network. BGP peering requires an IP-reachable external interface backed by the intended physical network. Here the requirement is instead to restore trustworthy event timelines and time-sensitive authentication; that step does not directly satisfy it.

C:

Inspect Edge health metrics and log volume, then tune retention or collection policy would address the separate case of edge health operations, where the objective is to avoid service instability from exhausted Edge resources. Edge resource pressure can impair gateway operation independently of route-policy correctness. Here the requirement is instead to restore trustworthy event timelines and time-sensitive authentication; that step does not directly satisfy it.

Question 489

A change review examines the following situation: Two business units share an NSX deployment but must manage only their assigned workloads and VPCs. Which practice would most directly undermine the requirement to give tenants self-service without cross-tenant administrative rights?

  1. granting both groups unrestricted NSX enterprise administrator privileges
  2. assuming private source addresses are automatically reachable from arbitrary internet routers
  3. making an Edge cluster redundant on paper without validating gateway service-router realization
  4. giving the application team broad access to all Edge clusters as a shortcut

Explanation

Correct Answer

A:

The anti-pattern, granting both groups unrestricted NSX enterprise administrator privileges, directly conflicts with the requirement to give tenants self-service without cross-tenant administrative rights. Projects provide administrative and policy boundaries for delegated networking. The safer action is to create separate Projects and scoped roles for the two business units.

Incorrect Answers

B:

That practice primarily harms the distinct vpc egress nat design activity, in which the goal is to supply a supported outbound translation path for the tenant. Its failure mechanism is less direct for this specific project isolation policy review. Here the key requirement is to give tenants self-service without cross-tenant administrative rights.

C:

That practice primarily harms the distinct edge ha service placement activity, in which the goal is to enforce the expected gateway HA placement on eligible Edge nodes. Its failure mechanism is less direct for this specific project isolation policy review. Here the key requirement is to give tenants self-service without cross-tenant administrative rights.

D:

That practice primarily harms the distinct onboarding delegation activity, in which the goal is to expose only approved self-service network capabilities. Its failure mechanism is less direct for this specific project isolation policy review. Here the key requirement is to give tenants self-service without cross-tenant administrative rights.

Question 490

A change review examines the following situation: A Tier-0 gateway drops packets under peak demand while BGP sessions stay established. Which practice would most directly undermine the requirement to recover dataplane headroom on the congested gateway?

  1. recreating the Tier-0 BGP peer solely because the Edge overlay TEP cannot reach hosts
  2. repeatedly changing BGP AS numbers while the Edge forwarding resource remains saturated
  3. restarting all NSX Managers and Edge nodes as the first troubleshooting step
  4. insisting on active-active stateful VRF parent mode despite NSX rejecting the topology

Explanation

Correct Answer

B:

The anti-pattern, repeatedly changing BGP AS numbers while the Edge forwarding resource remains saturated, directly conflicts with the requirement to recover dataplane headroom on the congested gateway. A saturated Edge can lose traffic even with a healthy routing control plane. The safer action is to inspect Edge CPU, memory, dataplane throughput and interface drops before resizing or scaling.

Incorrect Answers

A:

That practice primarily harms the distinct edge tep vlan inconsistency activity, in which the goal is to bring Edge transport traffic onto the intended tunnel network. Its failure mechanism is less direct for this specific edge resource exhaustion review. Here the key requirement is to recover dataplane headroom on the congested gateway.

C:

That practice primarily harms the distinct minimum-impact troubleshooting activity, in which the goal is to reduce incident blast radius while gathering reliable evidence. Its failure mechanism is less direct for this specific edge resource exhaustion review. Here the key requirement is to recover dataplane headroom on the congested gateway.

D:

That practice primarily harms the distinct vrf and stateful incompatibility activity, in which the goal is to avoid an unsupported Tier-0 architecture. Its failure mechanism is less direct for this specific edge resource exhaustion review. Here the key requirement is to recover dataplane headroom on the congested gateway.
