VMware 3V0-25.25 Practice Test 13
Question 120
A Project is retired, but stale VPCs and policies consume resources and confuse new tenants. The engineering team needs to remove the retired tenant without affecting shared provider infrastructure. What action best addresses the immediate requirement?
- apply resource quotas appropriate to the Project's service allocation
- configure route redistribution for the required connected and Tier-1 advertised sources
- configure a supported IPsec VPN service with matching proposals and routes
- inventory and decommission Project-owned resources in dependency order
Explanation
Correct Answer
D:Tenant offboarding should clean scoped objects while leaving shared routing and provider services intact. The selected action, inventory and decommission Project-owned resources in dependency order, directly supports the specified goal to remove the retired tenant without affecting shared provider infrastructure. A useful confirmation is: The retired Project has no leftover scoped VPCs or rules; other Projects remain healthy.
Incorrect Answers
A:Apply resource quotas appropriate to the Project's service allocation would address the separate case of quota on tenant segments, where the objective is to limit excessive network object creation for the tenant. Quotas constrain tenant consumption while allowing normal self-service within a supported boundary. Here the requirement is instead to remove the retired tenant without affecting shared provider infrastructure; that step does not directly satisfy it.
B:Configure route redistribution for the required connected and Tier-1 advertised sources would address the separate case of route redistribution sources, where the objective is to advertise eligible internal routes through the Tier-0. BGP adjacency alone does not guarantee that all relevant NSX network prefixes are exported. Here the requirement is instead to remove the retired tenant without affecting shared provider infrastructure; that step does not directly satisfy it.
C: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 remove the retired tenant without affecting shared provider infrastructure; that step does not directly satisfy it.
Question 121
A Tier-0 gateway can ping its leaf neighbor, but the peer is not exchanging production subnet routes. The engineering team needs to inspect the control-plane state and routes of the external peer. What action best addresses the immediate requirement?
- review Tier-0 BGP neighbor summary and advertised/received route tables
- verify supported session ownership and redirection behavior on the gateway
- inspect Edge interface and fabric switch port errors and drop counters
- enable the supported Transit Gateway Static redistribution source on the Tier-0
Explanation
Correct Answer
A:BGP state and prefix advertisements expose session or policy faults not visible in an ICMP test. The selected action, review Tier-0 BGP neighbor summary and advertised/received route tables, directly supports the specified goal to inspect the control-plane state and routes of the external peer. A useful confirmation is: The diagnosis identifies whether adjacency is established and which expected prefixes are missing.
Incorrect Answers
B:Verify supported session ownership and redirection behavior on the gateway would address the separate case of stateful return-path ownership, where the objective is to preserve stateful flow correctness under multiple Edge routes. A stateful HA service may direct a response to the Edge that owns its connection state. Here the requirement is instead to inspect the control-plane state and routes of the external peer; that step does not directly satisfy it.
C:Inspect Edge interface and fabric switch port errors and drop counters would address the separate case of interface counter evidence, where the objective is to determine whether the uplink interface is discarding packets. Interface-level counters can distinguish physical congestion or faults from logical policy denial. Here the requirement is instead to inspect the control-plane state and routes of the external peer; that step does not directly satisfy it.
D:Enable the supported Transit Gateway Static redistribution source on the Tier-0 would address the separate case of transit gateway route missing, where the objective is to advertise Transit Gateway routes required for VPC external access. VCF 9 VPC routes may depend on the explicit TGW static redistribution class. Here the requirement is instead to inspect the control-plane state and routes of the external peer; that step does not directly satisfy it.
Question 122
New guests attach to a segment but cannot obtain an IP address from the planned service. The engineering team needs to make the correct DHCP function available to segment members. What action best addresses the immediate requirement?
- assign the appropriate transport zone to eligible prepared hosts
- associate a supported DHCP server or relay configuration with the segment
- publish an approved external connectivity profile for the Project while retaining provider ownership
- check global-group scope and per-site realization status before repairing the targeting issue
Explanation
Correct Answer
B:DHCP clients require a valid service or relay path and usable address scope. The selected action, associate a supported DHCP server or relay configuration with the segment, directly supports the specified goal to make the correct DHCP function available to segment members. A useful confirmation is: A test guest receives an expected address, router and DNS settings from the designated scope.
Incorrect Answers
A:Assign the appropriate transport zone to eligible prepared hosts would address the separate case of transport zone eligibility, where the objective is to make the segment realizable where workloads are placed. Transport zone participation governs where segments can appear for workload attachment. Here the requirement is instead to make the correct DHCP function available to segment members; that step does not directly satisfy it.
C:Publish an approved external connectivity profile for the Project while retaining provider ownership would address the separate case of project external connection control, where the objective is to keep external connectivity changes under provider control. Central external connection controls prevent tenants from changing shared fabric routing. Here the requirement is instead to make the correct DHCP function available to segment members; that step does not directly satisfy it.
D:Check global-group scope and per-site realization status before repairing the targeting issue would address the separate case of global rule realization, where the objective is to realize intended global policy on every targeted Local Manager. A saved global object is not sufficient if the local site never realizes the policy. Here the requirement is instead to make the correct DHCP function available to segment members; that step does not directly satisfy it.
Question 123
A developer should manage application subnets but not edit provider External Connections. The engineering team needs to separate tenant self-service rights from provider-owned connectivity settings. What action best addresses the immediate requirement?
- use a private VPC subnet with appropriate project connectivity policy
- apply resource quotas appropriate to the Project's service allocation
- scope VPC roles so External Connection profiles remain with administrators
- route alert definitions to an accountable owner and a documented escalation policy
Explanation
Correct Answer
C:Provider connectivity objects govern shared external routing and must not become uncontrolled tenant settings. The selected action, scope VPC roles so External Connection profiles remain with administrators, directly supports the specified goal to separate tenant self-service rights from provider-owned connectivity settings. A useful confirmation is: The developer can add approved subnets but cannot alter the shared external connection profile.
Incorrect Answers
A:Use a private VPC subnet with appropriate project connectivity policy would address the separate case of private vpc subnet isolation, where the objective is to apply the approved private subnet and connectivity design. Private and public subnet choices differ in how they are exposed through external connections. Here the requirement is instead to separate tenant self-service rights from provider-owned connectivity settings; that step does not directly satisfy it.
B:Apply resource quotas appropriate to the Project's service allocation would address the separate case of quota on tenant segments, where the objective is to limit excessive network object creation for the tenant. Quotas constrain tenant consumption while allowing normal self-service within a supported boundary. Here the requirement is instead to separate tenant self-service rights from provider-owned connectivity settings; 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 separate tenant self-service rights from provider-owned connectivity settings; that step does not directly satisfy it.
Question 124
A reviewer must validate the intended NSX outcome. Situation: A business requires only production application subnets to leave the Tier-0 BGP session. Which result most directly demonstrates that the team can limit external routing announcements to approved networks?
- A complete workload flow and return packet trace succeed across the gateway.
- Edge dataplane uplink link status and neighbor reachability pass the intended tests.
- The investigation shows where the expected prefix stops being advertised or returned.
- An upstream table shows only the approved production prefixes from the gateway.
Explanation
Correct Answer
D:An upstream table shows only the approved production prefixes from the gateway. This observation validates the specified bgp prefix filtering outcome. Outbound routing policy prevents accidental advertisement of private or management networks.
Incorrect Answers
A:This would validate tier-0 deployment smoke test rather than the needed bgp prefix filtering result. A neighbor state alone cannot prove guest routes, policy, NAT and return path are correct. For the present case, the evidence must show that the team can limit external routing announcements to approved networks.
B:This would validate edge interface mapping rather than the needed bgp prefix filtering result. Management reachability does not establish external dataplane interface readiness. For the present case, the evidence must show that the team can limit external routing announcements to approved networks.
C:This would validate vpc troubleshooting order rather than the needed bgp prefix filtering result. VPC external reachability needs a complete forward and return path across all three tiers. For the present case, the evidence must show that the team can limit external routing announcements to approved networks.
Question 125
A reviewer must validate the intended NSX outcome. Situation: Two redundant NSX Edge VMs share one ESXi host and one physical uplink. Which result most directly demonstrates that the team can avoid correlated failures for a business-critical north-south path?
- An ESXi host outage leaves an alternate Edge and uplink path available for the service.
- The same class of permitted or blocked traffic is observed under the policy in both sites.
- A packet path trace shows local distributed routing and no mandatory Edge transit for that flow.
- The operations inventory lists each instance, Manager cluster, domain and owning team correctly.
Explanation
Correct Answer
A:An ESXi host outage leaves an alternate Edge and uplink path available for the service. This observation validates the specified failure-domain diversity outcome. Logical redundancy offers limited resilience when all members depend on one physical failure point.
Incorrect Answers
B:This would validate global security objects rather than the needed failure-domain diversity result. Global groups can match protected resources across sites while a central policy expresses common decisions. For the present case, the evidence must show that the team can avoid correlated failures for a business-critical north-south path.
C:This would validate same-host east-west locality rather than the needed failure-domain diversity result. Distributed routing localizes many inter-segment flows on transport hosts, avoiding a centralized Edge hop. For the present case, the evidence must show that the team can avoid correlated failures for a business-critical north-south path.
D:This would validate fleet inventory clarity rather than the needed failure-domain diversity result. Clear fleet-to-manager mapping prevents cross-instance errors during maintenance and troubleshooting. For the present case, the evidence must show that the team can avoid correlated failures for a business-critical north-south path.
Question 126
An architect wants Tier-0 VRFs while using active-active stateful gateway mode. The engineering team needs to choose a supported combination of VRF and stateful HA features. What action best addresses the immediate requirement?
- use distributed firewall policy at the workload interface
- use active-active stateless or active-standby for Tier-0 VRF design as the service needs dictate
- monitor Edge CPU, throughput, packet drops and relevant service counters
- apply suitable prefix filtering or route-map policy to Tier-0 route export
Explanation
Correct Answer
B:Broadcom documents that a VRF gateway is not supported on an active-active stateful parent Tier-0. The selected action, use active-active stateless or active-standby for Tier-0 VRF design as the service needs dictate, directly supports the specified goal to choose a supported combination of VRF and stateful HA features. A useful confirmation is: Validation succeeds when the VRF parent uses a supported Tier-0 HA mode.
Incorrect Answers
A:Use distributed firewall policy at the workload interface would address the separate case of distributed versus gateway firewall, where the objective is to apply security where that east-west flow actually travels. Gateway firewall policy alone cannot inspect a flow that never reaches the external service boundary. Here the requirement is instead to choose a supported combination of VRF and stateful HA features; that step does not directly satisfy it.
C:Monitor Edge CPU, throughput, packet drops and relevant service counters would address the separate case of edge capacity indicators, where the objective is to detect bottlenecks on centralized Edge services. Central gateway resources may saturate even when distributed host networking is healthy. Here the requirement is instead to choose a supported combination of VRF and stateful HA features; that step does not directly satisfy it.
D:Apply suitable prefix filtering or route-map policy to Tier-0 route export would address the separate case of bgp prefix filtering, where the objective is to limit external routing announcements to approved networks. Outbound routing policy prevents accidental advertisement of private or management networks. Here the requirement is instead to choose a supported combination of VRF and stateful HA features; that step does not directly satisfy it.
Question 127
An architect proposes the following step: deploy suitable NSX Edge capacity and associate service routers with the needed gateways. The context is: An application needs north-south BGP reachability and a centralized NAT service. What is the strongest technical reason for that decision?
- The Manager API and user interface manage desired state; workload switching and routing occur in distributed or Edge data-plane components.
- TEP reachability enables overlay transport; it does not itself authorize guest-to-guest connections.
- Edge nodes host centralized service-router functions that cannot be implemented solely by hypervisor distributed forwarding.
- Fleet-wide observability can correlate health and capacity without turning local NSX management into a packet forwarding tier.
Explanation
Correct Answer
C:Edge nodes host centralized service-router functions that cannot be implemented solely by hypervisor distributed forwarding. This explains the proposed decision in the current edge services situation. The intended outcome is to place stateful and external-routing services in the right data plane, and verification would show: The service gateway is realized on appropriate Edge nodes and external routes and NAT translation operate.
Incorrect Answers
A:This statement can describe a manager control plane problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to manage logical network configuration centrally without hairpinning every packet; here the relevant requirement is to place stateful and external-routing services in the right data plane.
B:This statement can describe a underlay versus overlay security problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to distinguish fabric reachability from application access control; here the relevant requirement is to place stateful and external-routing services in the right data plane.
D: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 place stateful and external-routing services in the right data plane.
Question 128
An architect proposes the following step: design site-aware Tier-0/Edge egress so eligible traffic exits near its origin. The context is: A multi-site design currently sends all local internet traffic to a distant site even when local exits exist. What is the strongest technical reason for that decision?
- Supported lifecycle ordering and interop matrices reduce control-plane and host-version conflicts.
- Overlapping infrastructure addresses create ambiguity in cross-site control and tunnel connectivity.
- Distributed routing localizes many inter-segment flows on transport hosts, avoiding a centralized Edge hop.
- Local egress can reduce latency and cross-site dependency if routing and policy permit it.
Explanation
Correct Answer
D:Local egress can reduce latency and cross-site dependency if routing and policy permit it. This explains the proposed decision in the current edge locality across sites situation. The intended outcome is to reduce unnecessary intersite traffic for site-local workloads, and verification would show: A traced local workload flow exits through the intended local service and uplink path.
Incorrect Answers
A:This statement can describe a fleet lifecycle sequencing problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to avoid breaking supported component interoperability during maintenance; here the relevant requirement is to reduce unnecessary intersite traffic for site-local workloads.
B:This statement can describe a inter-site address planning problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to avoid conflicting transport and management addresses across site boundaries; here the relevant requirement is to reduce unnecessary intersite traffic for site-local workloads.
C:This statement can describe a same-host east-west locality problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to minimize unnecessary network transit while retaining routed segmentation; here the relevant requirement is to reduce unnecessary intersite traffic for site-local workloads.
Question 129
An architect proposes the following step: allocate distinct nonoverlapping IP subnets in the shared routing domain. The context is: Two departments assign the same subnet to routable segments in one shared routing context. What is the strongest technical reason for that decision?
- Overlapping directly connected networks in one route context can produce ambiguous traffic delivery.
- VLAN-backed segments use physical tagged forwarding for integration with non-overlay devices.
- The defined connectivity profile and Transit Gateway determine how tenant subnets access external networks.
- Role scopes keep troubleshooting visibility separate from potentially disruptive provider actions.
Explanation
Correct Answer
A:Overlapping directly connected networks in one route context can produce ambiguous traffic delivery. This explains the proposed decision in the current segment ip subnet plan situation. The intended outcome is to avoid ambiguous route selection between workload segments, and verification would show: The Tier-1 route table shows unique network destinations for both segments.
Incorrect Answers
B:This statement can describe a vlan segment creation problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to extend the designated physical L2 network to the virtual interface; here the relevant requirement is to avoid ambiguous route selection between workload segments.
C:This statement can describe a vpc transit gateway association problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to join the VPC through its designated connectivity profile and Transit Gateway path; here the relevant requirement is to avoid ambiguous route selection between workload segments.
D:This statement can describe a role separation problem but is not the technical cause addressed by the proposed step. In that other situation the objective is to apply least privilege to tenant visibility and configuration; here the relevant requirement is to avoid ambiguous route selection between workload segments.
Question 130
A change review examines the following situation: Two VMs share an overlay segment but reside on different ESXi hosts. Which practice would most directly undermine the requirement to identify transport encapsulation between hosts for Layer-2 delivery?
- assessing only same-segment Layer-2 switching for traffic between independent Tier-1 networks
- assuming physical leaf switches forward the raw tenant MAC frame without encapsulation
- using only an individual VM performance chart as an end-to-end network map
- rewriting firewall policy before looking at the dropping interface counters
Explanation
Correct Answer
B:The anti-pattern, assuming physical leaf switches forward the raw tenant MAC frame without encapsulation, directly conflicts with the requirement to identify transport encapsulation between hosts for Layer-2 delivery. The underlay forwards TEP packets while the overlay carries the tenant frame across hosts. The safer action is to trace source vNIC, source TEP GENEVE encapsulation, underlay, destination TEP and vNIC.
Incorrect Answers
A:That practice primarily harms the distinct two tier-1 gateways through tier-0 activity, in which the goal is to describe the route boundary between independent application gateway contexts. Its failure mechanism is less direct for this specific cross-host same-segment packet walk review. Here the key requirement is to identify transport encapsulation between hosts for Layer-2 delivery.
C:That practice primarily harms the distinct vcf operations for networks path activity, in which the goal is to correlate virtual and physical network dependencies for the application. Its failure mechanism is less direct for this specific cross-host same-segment packet walk review. Here the key requirement is to identify transport encapsulation between hosts for Layer-2 delivery.
D:That practice primarily harms the distinct interface counter evidence activity, in which the goal is to determine whether the uplink interface is discarding packets. Its failure mechanism is less direct for this specific cross-host same-segment packet walk review. Here the key requirement is to identify transport encapsulation between hosts for Layer-2 delivery.
