VMware 3V0-25.25 Practice Test 74
Question 730
A global security rule was created but does not appear in enforcement at one connected site. The engineering team needs to realize intended global policy on every targeted Local Manager. What action best addresses the immediate requirement?
- schedule Global Manager backups and rehearse supported restoration
- check global-group scope and per-site realization status before repairing the targeting issue
- coordinate trunk VLAN admission with the switch team
- configure a supported IPsec VPN service with matching proposals and routes
Explanation
Correct Answer
B:A saved global object is not sufficient if the local site never realizes the policy. The selected action, check global-group scope and per-site realization status before repairing the targeting issue, directly supports the specified goal to realize intended global policy on every targeted Local Manager. A useful confirmation is: The intended rule and group show successful realization at the affected local site.
Incorrect Answers
A:Schedule Global Manager backups and rehearse supported restoration would address the separate case of global backup recovery, where the objective is to recover the shared management intent with a tested procedure. Recovery needs trustworthy backups of global policy and a procedure to restore management relationships. Here the requirement is instead to realize intended global policy on every targeted Local Manager; that step does not directly satisfy it.
C:Coordinate trunk VLAN admission with the switch team would address the separate case of physical vlan availability, where the objective is to make the physical fabric carry the VLAN used by the NSX segment. A VLAN-backed NSX network depends on the underlying tagged L2 connectivity. Here the requirement is instead to realize intended global policy on every targeted Local Manager; that step does not directly satisfy it.
D:Configure a supported IPsec VPN service with matching proposals and routes would address the separate case of ipsec vpn connectivity, where the objective is to protect data in transit between controlled gateway endpoints. IPsec negotiates security associations and encrypts traffic for the agreed protected networks. Here the requirement is instead to realize intended global policy on every targeted Local Manager; that step does not directly satisfy it.
Question 731
An architect proposes the following step: use active-active stateless or active-standby for Tier-0 VRF design as the service needs dictate. The context is: An architect wants Tier-0 VRFs while using active-active stateful gateway mode. What is the strongest technical reason for that decision?
- Automation credentials must follow least privilege and supported policy resource paths.
- BFD can detect dataplane liveness failure faster and trigger routing convergence where supported.
- Broadcom documents that a VRF gateway is not supported on an active-active stateful parent Tier-0.
- A wrong transport VLAN prevents endpoint IP traffic from reaching the required underlay even if VMs are powered on.
Explanation
Correct Answer
C:Broadcom documents that a VRF gateway is not supported on an active-active stateful parent Tier-0. This explains the proposed decision in the current tier-0 stateful ha constraint situation. The intended outcome is to choose a supported combination of VRF and stateful HA features, and verification would show: Validation succeeds when the VRF parent uses a supported Tier-0 HA mode.
Incorrect Answers
A:This statement can describe a network policy api scope problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to restrict automated NSX changes to the intended object boundary; here the relevant requirement is to choose a supported combination of VRF and stateful HA features.
B:This statement can describe a bgp keepalive behavior problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to shorten supported route-failure detection time; here the relevant requirement is to choose a supported combination of VRF and stateful HA features.
D:This statement can describe a uplink profile vlan problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to match the TEP VLAN tagging expected by the physical trunk; here the relevant requirement is to choose a supported combination of VRF and stateful HA features.
Question 732
A change review examines the following situation: Two teams give different meanings to the same network name across VCF instances. Which practice would most directly undermine the requirement to reduce confusion when automating or auditing fleet network objects?
- backhauling every inter-segment packet through the remote Edge cluster
- comparing unrelated peak-hour and quiet-hour traffic without normalizing load
- ignoring time skew because raw IP ping between managers succeeds
- using one ambiguous short segment name everywhere with no instance identifier
Explanation
Correct Answer
D:The anti-pattern, using one ambiguous short segment name everywhere with no instance identifier, directly conflicts with the requirement to reduce confusion when automating or auditing fleet network objects. Unique naming and ownership metadata help distinguish otherwise similar segments or gateways. The safer action is to standardize object naming with explicit fleet, site and workload scope.
Incorrect Answers
A:That practice primarily harms the distinct same-host east-west locality activity, in which the goal is to minimize unnecessary network transit while retaining routed segmentation. Its failure mechanism is less direct for this specific shared naming conventions review. Here the key requirement is to reduce confusion when automating or auditing fleet network objects.
B:That practice primarily harms the distinct reproducible optimization activity, in which the goal is to validate a performance change using controlled measurements. Its failure mechanism is less direct for this specific shared naming conventions review. Here the key requirement is to reduce confusion when automating or auditing fleet network objects.
C:That practice primarily harms the distinct ntp and dns prerequisites activity, in which the goal is to establish consistent fundamental management services. Its failure mechanism is less direct for this specific shared naming conventions review. Here the key requirement is to reduce confusion when automating or auditing fleet network objects.
Question 733
A VPC workload reaches internal peers but cannot reach a corporate site outside the VCF fabric. The engineering team needs to isolate VPC routing, advertisement and upstream return-path faults. What action best addresses the immediate requirement?
- trace the VPC subnet to Transit Gateway, Tier-0 redistribution and physical peer routes
- associate the correct project VPC connectivity configuration and inspect Transit Gateway routes
- apply appropriate NSX DFW groups and policy for the segment's workloads
- add the correct overlay transport zone to participating transport nodes
Explanation
Correct Answer
A:VPC external reachability needs a complete forward and return path across all three tiers. The selected action, trace the VPC subnet to Transit Gateway, Tier-0 redistribution and physical peer routes, directly supports the specified goal to isolate VPC routing, advertisement and upstream return-path faults. A useful confirmation is: The investigation shows where the expected prefix stops being advertised or returned.
Incorrect Answers
B:Associate the correct project VPC connectivity configuration and inspect Transit Gateway routes would address the separate case of vpc transit gateway association, where the objective is to join the VPC through its designated connectivity profile and Transit Gateway path. The defined connectivity profile and Transit Gateway determine how tenant subnets access external networks. Here the requirement is instead to isolate VPC routing, advertisement and upstream return-path faults; that step does not directly satisfy it.
C:Apply appropriate NSX DFW groups and policy for the segment's workloads would address the separate case of segment security placement, where the objective is to ensure connecting a VM to a segment does not bypass microsegmentation policy. Logical network membership alone is not a substitute for workload-level access control. Here the requirement is instead to isolate VPC routing, advertisement and upstream return-path faults; that step does not directly satisfy it.
D:Add the correct overlay transport zone to participating transport nodes would address the separate case of overlay zone membership, where the objective is to make that cluster eligible for the required logical overlay segment. Transport-zone membership controls where a segment can be realized. Here the requirement is instead to isolate VPC routing, advertisement and upstream return-path faults; that step does not directly satisfy it.
Question 734
An architect proposes the following step: trace the VPC subnet to Transit Gateway, Tier-0 redistribution and physical peer routes. The context is: A VPC workload reaches internal peers but cannot reach a corporate site outside the VCF fabric. What is the strongest technical reason for that decision?
- Active-active service routers can forward external routing traffic on multiple Edge nodes where supported.
- VPC external reachability needs a complete forward and return path across all three tiers.
- Overlapping private IPs can coexist only when their routing contexts and interconnect policies avoid ambiguity.
- Avi adds application-aware balancing and backend health handling beyond ordinary IP routing.
Explanation
Correct Answer
B:VPC external reachability needs a complete forward and return path across all three tiers. This explains the proposed decision in the current vpc troubleshooting order situation. The intended outcome is to isolate VPC routing, advertisement and upstream return-path faults, and verification would show: The investigation shows where the expected prefix stops being advertised or returned.
Incorrect Answers
A:This statement can describe a tier-0 ha mode choice problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to enable supported multi-path forwarding at the external routing tier; here the relevant requirement is to isolate VPC routing, advertisement and upstream return-path faults.
C:This statement can describe a overlapping tenant addressing problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to preserve tenant route-context isolation when address overlap is permitted; here the relevant requirement is to isolate VPC routing, advertisement and upstream return-path faults.
D:This statement can describe a avi load-balancer service problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to implement a managed application load-balancing layer; here the relevant requirement is to isolate VPC routing, advertisement and upstream return-path faults.
Question 735
A change review examines the following situation: A newly prepared host must participate in only the overlay networks assigned to its compute cluster. Which practice would most directly undermine the requirement to scope which NSX logical segments can be realized on the host?
- forcing all regional workloads through one distant Edge without a business reason
- placing the physical BGP neighbor relationship on a Layer-2-only segment
- assigning unrelated transport zones in the hope that all segments become reachable
- equating additional Edge VMs on one host with fault-domain redundancy
Explanation
Correct Answer
C:The anti-pattern, assigning unrelated transport zones in the hope that all segments become reachable, directly conflicts with the requirement to scope which NSX logical segments can be realized on the host. Transport zones determine which logical networks are available to participating transport nodes. The safer action is to attach the applicable overlay transport zone through the transport-node preparation.
Incorrect Answers
A:That practice primarily harms the distinct edge locality across sites activity, in which the goal is to reduce unnecessary intersite traffic for site-local workloads. Its failure mechanism is less direct for this specific transport zones review. Here the key requirement is to scope which NSX logical segments can be realized on the host.
B:That practice primarily harms the distinct tier-0 north-south role activity, in which the goal is to establish a routing boundary between virtualized workloads and physical fabric. Its failure mechanism is less direct for this specific transport zones review. Here the key requirement is to scope which NSX logical segments can be realized on the host.
D:That practice primarily harms the distinct capacity versus redundancy activity, in which the goal is to design both service headroom and independent failure capacity. Its failure mechanism is less direct for this specific transport zones review. Here the key requirement is to scope which NSX logical segments can be realized on the host.
Question 736
A reviewer must validate the intended NSX outcome. Situation: An Edge uplink is connected to a trunk but cannot ping the upstream router on the intended subnet. Which result most directly demonstrates that the team can repair the physical uplink addressing or VLAN mismatch before routing configuration?
- Unhealthy backends stop receiving new eligible traffic through the virtual service.
- The cluster contains healthy new Edge members and gateway headroom improves.
- Traffic stays isolated and any allowed external translation uses the intended tenant context.
- Neighbor reachability succeeds on the uplink subnet after correcting the mismatch.
Explanation
Correct Answer
D:Neighbor reachability succeeds on the uplink subnet after correcting the mismatch. This observation validates the specified underlay peer troubleshooting outcome. External BGP cannot form until the directly connected dataplane path works.
Incorrect Answers
A:This would validate avi load-balancer service rather than the needed underlay peer troubleshooting result. Avi adds application-aware balancing and backend health handling beyond ordinary IP routing. For the present case, the evidence must show that the team can repair the physical uplink addressing or VLAN mismatch before routing configuration.
B:This would validate edge scaling lifecycle rather than the needed underlay peer troubleshooting result. Extra Edge VMs contribute only after successful transport preparation and service placement. For the present case, the evidence must show that the team can repair the physical uplink addressing or VLAN mismatch before routing configuration.
C:This would validate overlapping tenant addressing rather than the needed underlay peer troubleshooting result. Overlapping private IPs can coexist only when their routing contexts and interconnect policies avoid ambiguity. For the present case, the evidence must show that the team can repair the physical uplink addressing or VLAN mismatch before routing configuration.
Question 737
An architect proposes the following step: integrate VMware Avi Load Balancer and configure virtual services with health-monitored pools. The context is: Applications require a virtual IP with backend health checks across multiple VCF workload nodes. What is the strongest technical reason for that decision?
- Avi adds application-aware balancing and backend health handling beyond ordinary IP routing.
- Time-ordered logs can show routing state changes and related process errors more precisely than an aggregate green/red health icon.
- Transport zone participation governs where segments can appear for workload attachment.
- Preflight validation catches wrong paths, permissions, or rule matches before broad production execution.
Explanation
Correct Answer
A:Avi adds application-aware balancing and backend health handling beyond ordinary IP routing. This explains the proposed decision in the current avi load-balancer service situation. The intended outcome is to implement a managed application load-balancing layer, and verification would show: Unhealthy backends stop receiving new eligible traffic through the virtual service.
Incorrect Answers
B:This statement can describe a centralized logs problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to correlate timestamped NSX gateway and neighbor events; here the relevant requirement is to implement a managed application load-balancing layer.
C:This statement can describe a transport zone eligibility problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to make the segment realizable where workloads are placed; here the relevant requirement is to implement a managed application load-balancing layer.
D:This statement can describe a integration change testing problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to avoid unintended multi-site changes from automation drift; here the relevant requirement is to implement a managed application load-balancing layer.
Question 738
A tenant needs multiple northbound paths with stateless external routing and sufficient Edge capacity. The engineering team needs to support north-south path sharing without a single forwarding Edge. What action best addresses the immediate requirement?
- plan the stretched segment with required intersite tunnel and transport readiness
- design an active-active Tier-0 with healthy external peerings and compatible services
- enforce distributed firewall rules using workload group membership
- measure before-and-after path latency, packet loss and Edge utilization
Explanation
Correct Answer
B:Active-active service-router routing permits multiple Edge paths when configuration and service constraints allow. The selected action, design an active-active Tier-0 with healthy external peerings and compatible services, directly supports the specified goal to support north-south path sharing without a single forwarding Edge. A useful confirmation is: BGP and path observations show eligible external flows using multiple healthy Edge paths.
Incorrect Answers
A:Plan the stretched segment with required intersite tunnel and transport readiness would address the separate case of stretched network eligibility, where the objective is to extend an eligible overlay segment between supported Federation locations. A stretched logical network depends on supported Federation design and working cross-site transport connectivity. Here the requirement is instead to support north-south path sharing without a single forwarding Edge; 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 support north-south path sharing without a single forwarding Edge; that step does not directly satisfy it.
D:Measure before-and-after path latency, packet loss and Edge utilization would address the separate case of latency baseline, where the objective is to identify whether networking datapath is the actual bottleneck. A comparable baseline distinguishes network forwarding delay from application processing or storage latency. Here the requirement is instead to support north-south path sharing without a single forwarding Edge; that step does not directly satisfy it.
Question 739
A change review examines the following situation: An Edge needs routable connectivity to physical routers before a Tier-0 can form a BGP peer. Which practice would most directly undermine the requirement to prepare the VLAN-backed Edge uplink network?
- manually adding host IPs without first validating required vCenter integration
- stacking both redundant Edge VMs and their uplinks on one host
- attempting BGP over an unconnected management-only interface
- using an NSX Tier-0 BGP neighbor as if it performed HTTP backend health checks
Explanation
Correct Answer
C:The anti-pattern, attempting BGP over an unconnected management-only interface, directly conflicts with the requirement to prepare the VLAN-backed Edge uplink network. BGP peering requires an IP-reachable external interface backed by the intended physical network. The safer action is to create an eligible VLAN segment and connect the Edge external uplink to the correct fabric VLAN.
Incorrect Answers
A:That practice primarily harms the distinct compute manager integration activity, in which the goal is to make vSphere compute resources visible for integrated NSX operations. Its failure mechanism is less direct for this specific edge uplink segment review. Here the key requirement is to prepare the VLAN-backed Edge uplink network.
B:That practice primarily harms the distinct edge failure-domain placement activity, in which the goal is to protect gateway forwarding from a single host loss. Its failure mechanism is less direct for this specific edge uplink segment review. Here the key requirement is to prepare the VLAN-backed Edge uplink network.
D:That practice primarily harms the distinct avi load-balancer service activity, in which the goal is to implement a managed application load-balancing layer. Its failure mechanism is less direct for this specific edge uplink segment review. Here the key requirement is to prepare the VLAN-backed Edge uplink network.
Question 740
Two ESXi transport nodes require consistent uplink mapping and tunneling policy. The engineering team needs to apply repeatable physical-uplink mapping during NSX preparation. What action best addresses the immediate requirement?
- prepare the cluster as NSX transport nodes with compatible switching and transport-zone assignment
- use supported Edge dataplane acceleration such as DPDK where the platform provides it
- keep the eligible east-west path on distributed logical routing
- define and use the applicable uplink profile in transport-node configuration
Explanation
Correct Answer
D:Uplink profiles capture NIC teaming, transport VLAN, and uplink placement decisions for the prepared node. The selected action, define and use the applicable uplink profile in transport-node configuration, directly supports the specified goal to apply repeatable physical-uplink mapping during NSX preparation. A useful confirmation is: Both nodes show the expected uplink-profile mapping and healthy TEP connectivity.
Incorrect Answers
A:Prepare the cluster as NSX transport nodes with compatible switching and transport-zone assignment would address the separate case of transport node eligibility, where the objective is to turn ordinary hypervisor hosts into participating NSX data-plane nodes. Being managed by vCenter does not by itself create NSX transport-node participation. Here the requirement is instead to apply repeatable physical-uplink mapping during NSX preparation; that step does not directly satisfy it.
B:Use supported Edge dataplane acceleration such as DPDK where the platform provides it would address the separate case of edge fast packet processing, where the objective is to use an optimized software data path on suitably sized Edge resources. DPDK-based packet processing reduces generic kernel forwarding overhead for supported Edge paths. Here the requirement is instead to apply repeatable physical-uplink mapping during NSX preparation; that step does not directly satisfy it.
C:Keep the eligible east-west path on distributed logical routing would address the separate case of same-host east-west locality, where the objective is to minimize unnecessary network transit while retaining routed segmentation. Distributed routing localizes many inter-segment flows on transport hosts, avoiding a centralized Edge hop. Here the requirement is instead to apply repeatable physical-uplink mapping during NSX preparation; that step does not directly satisfy it.
