VMware Advanced VMware Cloud Foundation 9.0 Networking - 3V0-25.25 Exam Questions
QUESTION NO: 1
An administrator is preparing to deploy a new workload domain that will host vSphere Kubernetes Service (VKS) clusters. Before configuring the network for the Kubernetes clusters, the administrator needs to create a Tier-0 Gateway to handle North/South connectivity. What is the requirement for creating a Tier-0 Gateway for use with a workload domain that is running the vSphere Kubernetes service (VKS) with VPC?

QUESTION NO: 3
An administrator has been tasked with enabling OSPF as the routing protocol for a Tier-0 Gateway. Which two items must be configured to enable OSPF for a Tier-0 Gateway?
Mark two answers by clicking the two correct locations on the image. (Choose two.)
An administrator has been tasked with enabling OSPF as the routing protocol for a Tier-0 Gateway. Which two items must be configured to enable OSPF for a Tier-0 Gateway?
Mark two answers by clicking the two correct locations on the image. (Choose two.)
Correct Answer:
Explanation:
To enable OSPF on a Tier-0 Gateway within a VMware Cloud Foundation (VCF) or NSX environment, an administrator must define the areas where the gateway will participate and the specific interfaces it will use for peering.
Based on the NSX Manager configuration interface, the two required items to be configured are:
* Area Definition: This is necessary to define the OSPF area (e.g., Area 0) the Tier-0 gateway will participate in.
* OSPF Configured Interfaces: OSPF must be explicitly configured on the relevant uplink interfaces to establish neighbor relationships and exchange routing information with physical routers.
QUESTION NO: 4
An administrator has noticed that both the active and standby Global Managers have gone offline.
What is the correct sequence of events to restore the Global Managers?
An administrator has noticed that both the active and standby Global Managers have gone offline.
What is the correct sequence of events to restore the Global Managers?
Correct Answer:
Explanation:
* Step 1: Delete both the active and standby Global Managers. Ensure there are no Global Manager appliances up in any other clusters.
* Step 2: Deploy a new Global Manager with the same IP address/FQDN as the old active Global Manager.
* Step 3: Restore the active Global Manager from backup.
* Step 4: Deploy an additional new Global Manager on another site and onboard it to the restored Global Manager.
In aVMware Cloud Foundationmulti-site deployment usingNSX Federation, the Global Manager (GM) manages the global networking configuration across multiple sites. If the entire GM cluster (Active and Standby) fails, the following architectural principles apply:
* Cleanup (Step 1):Before initiating a restore, the environment must be "cleaned." If old, failed VMs remain in the inventory or on the hosts, they can cause IP address conflicts or UUID mismatches during the deployment of the new appliance. You must ensure the management plane is clear of the original failed nodes.
* Identity Consistency (Step 2):When restoring an NSX appliance (Local or Global) from backup, the new appliancemustbe deployed with the exact sameIP address and FQDNas the original active node.
This is critical because the existing Local Managers (LMs) at each site already have established thumbprints and communication channels tied to that specific identity.
* The Restore Operation (Step 3):Once the "seed" appliance is deployed, the restore process is triggered through the NSX Manager UI/API. This process re-populates the database with the global segments, firewall rules, and Tier-0/Tier-1 configurations.
* Restoring Redundancy (Step 4):The backup only contains the configuration of the cluster. It does not
"restore" the standby VM itself. High Availability (HA) must be manually re-established by deploying a second GM appliance at the secondary site and joining it to the newly restored Global Manager cluster to act as the standby.
QUESTION NO: 5
When attempting to deploy or expand an edge cluster from an administrator encounters a failure: "Failed to validate the BGP Route Distribution". Prior to calling support, the administrator attempts to troubleshoot the issue. How should the administrator troubleshoot this issue?

QUESTION NO: 6
An administrator needs to prevent the datacenter from advertising any internal prefixes toward a new VPC, while still ensuring the VPC receives a default route learned from the datacenter's upstream network. Where should the routing policy be applied?
