The 3V0-25.25 exam, officially titled Advanced VMware Cloud Foundation 9.0 Networking, is the qualifying exam for the VMware Certified Advanced Professional - VMware Cloud Foundation 9.0 Networking certification, which sits at the Professional level. Earning it shows employers that you have the skills the credential stands for, and it is a solid step forward on a VMware career path. It also connects to VMware Certified Professional - Data Center Virtualization (VCP-DCV), VMware Cloud Foundation Specialist certifications, so the effort you put in now keeps paying off as you advance.
The 3V0-25.25 exam gives you 60-70 questions to complete within 135-150. Do the math before exam day: divide the total time by the question count to set a steady per-question pace, and flag any item that stalls you so you can return to it after securing the easier points. The most reliable way to build that rhythm is a full timed practice test under the same limit, which is exactly what TestSimulate's test engines are designed for.
The passing score for VMware Advanced VMware Cloud Foundation 9.0 Networking is Scaled score 300 (on a 100-500 scale), and the official registration fee is USD 250-450 (varies by region). Keep in mind that a retake means paying that fee again in full, which makes an honest self-check worthwhile: before you book, sit a timed practice test and make sure you are consistently scoring above the passing line with some margin to spare.
According to the official requirements: Recommended: VMware Certified Professional (VCP-DCV) or equivalent hands-on experience with VMware Cloud Foundation and NSX networking.

An architect has just deployed a new NSX Edge cluster in a VMware Cloud Foundation (VCF) fleet. The BGP peer between the NSX Tier-0 gateway and the top-of-rack routers is successfully up and stable.
* BGP Connection is established, but the NSX Tier-0 is not receiving a default route from the top-of-rack routers.
* Workloads inside NSX have no Internet access.
What could be the solution?
Correct Answer: C 🗳️
Explanation: Only visible for TestSimulate members. You can sign-up / login (it's free).
An administrator is troubleshooting BGP flapping in a VMware Cloud Foundation (VCF) 9 environment. A Tier-0 Gateway is running in Active/Active mode with two Edge nodes. BFD is enabled on the eBGP sessions to the upstream routers. Each Edge node uses its own uplink IP for BGP. After some network maintenance, one BGP session starts flapping every few minutes. The other BGP sessions stay stable. On the affected Edge node, the command get bfd-sessions shows:
* State: Down
* Diag: Detect Time Expired
Symptoms:
* The upstream router also shows the BFD session as Down with control Detection Time Expired.
* There are no interface errors, no packet loss for normal traffic, and clearing the BFD session temporarily brings it back up - but it flaps again after few minutes.
What is the root cause?

An administrator is responsible for the management of a VMware Cloud Foundation (VCF) Fleet that consists of two VCF instances that are located in different physical locations. The administrator has been tasked with configuring a VPN between the two locations and has been tasked with identifying the two supported NSX Gateway configurations for an IPSec VPN. Drag and drop two items from the list of Possible Configurations into the list of Supported Configurations in any order.(Choose two.)
Correct Answer:

Explanation:
* Active-Standby Tier-0 Gateway
* Active-Standby Tier-1 Gateway
In aVMware Cloud Foundation (VCF)multi-site or multi-instance architecture, established viaNSX Federation, secure connectivity between sites is often achieved throughIPSec VPN. IPSec VPN is considered a stateful service within the NSX networking stack.
Stateful services-which also include NAT and Load Balancing-require a centralized point of processing to maintain the security association (SA) and session state tables. In the NSX gateway architecture, this necessitates the presence of aService Router (SR)component. For stateful consistency and to avoid session disruption that would occur if asymmetric traffic were processed by different nodes, these gateways must operate in anActive-Standbyhigh-availability mode.
According to the "NSX-T Data Center VPN Configuration Guide," IPSec VPN services can be deployed on either the provider tier (Tier-0 Gateway) or the tenant tier (Tier-1 Gateway). When configured on a Tier-0 gateway, the VPN typically provides broad connectivity between the physical infrastructure of two sites.
When configured on a Tier-1 gateway, it often provides targeted connectivity for a specific project or department's workload segments.
Configurations involvingActive-Activegateways (whether Tier-0 or Tier-1) do not support the native NSX IPSec VPN service because the ECMP (Equal Cost Multi-Pathing) nature of Active-Active mode could lead to packets belonging to the same VPN tunnel being processed by different Edge nodes, which cannot share the real-time encryption state. Therefore, for an administrator to successfully implement a cross-location VPN in a VCF Fleet, they must ensure the target gateway-be it Tier-0 or Tier-1-is deployed inActive-Standby mode.
When using a DHCP Relay on a segment, which design restriction must be considered?

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.
