Question 1
Single choice

An administrator changed the SFTP server used for scheduled NSX Manager backups. The backup jobs now fail with the error "Host KEY Verification Failed." The connectivity and credentials are correct.

How would an administrator resolve the error?

A.

Turn Off Backup encryption.

B.

Update the SSH fingerprint.

C.

Trust the certificate on the SFTP server.

D.

Use the NSX cluster VIP as the SFTP endpoint.

Question 2
Single choice

A sovereign cloud provider has a VMware Cloud Foundation (VCF) stretched Workload Domain across two data centers (AZ1 and AZ2), where site connectivity via Layer 3 is provided by the underlay.

The following NSX details are included in the design:

- Each site must host its own local NSX Edge Cluster for availability zones.
- Tier-0 gateways must be configured in active/active mode with BGP ECMP to local top-of-rack switches.
- Inter-site Edge TEP traffic must not cross the inter-DC link.
- SDDC Manager is used to automate NSX deployment.

During deployment of the Edge Cluster for AZ2, the SDDC Manager workflow fails because the Edge transport nodes' TEP IPs are not reachable from the ESXi transport nodes.

Which step ensures correct Edge Cluster deployment in multi-site stretched domains?

A.

Disable the liveness check during Edge deployment in SDDC Manager.

B.

Configure BGP neighbors before deploying the Edge Cluster.

C.

Reuse the TEP IP pool from AZ1.

D.

Create an AZ2-specific Edge TEP IP pool and map it to the AZ2 uplink profile before deploying the Edge Cluster.

Question 3
Single choice

An administrator has noticed an issue in a freshly deployed VMware Cloud Foundation (VCF) environment where the BGP neighborship between the Tier-0 gateway and a physical router remains in the Idle state.
Pings between the uplink IPs are successful.

What is the issue?

A.

Autonomous System number mismatch.

B.

Distributed Firewall blocking traffic.

C.

Geneve tunnel down.

D.

Overlay MTU too low.

Question 4
Single choice

An administrator is tasked to create a development environment with a Tier-1 gateway to host overlay segments for only East/West workload communication. North/South communication is also required. The solution will not include the following services: NAT, DHCP, VPN.

Which step must the administrator take when creating the Tier-1 gateway?

A.

Configure a Service Interface on the Tier-1 gateway to connect each overlay segment to provide the East /West communication.

B.

Enable route advertisement and connect the Tier-1 gateway to the Tier-0 gateway.

C.

Assign the Tier-1 gateway to an Edge Cluster before any segments are created.

D.

Keep route advertisement disabled and leave the Tier-1 gateway disconnected from any Tier-0 gateway.

Question 5
Single choice

An NSX Manager cluster has failed. The administrator deployed a new NSX Manager using the latest version and attempted to restore from a backup, but the restore operation failed.

What would an administrator do to recover the cluster?

A.

Edit the backup passphrase to match the new build.

B.

Use SDDC Manager to replace NSX Manager.

C.

Use the NSX restore API instead of the UI.

D.

Deploy an NSX Manager that matches the backup's build.

Question 6
Single choice

An administrator is troubleshooting why workloads in NSX cannot reach the external network
10.100.0.0/16.

The Tier-0 Gateway is in Active/Active mode and has the following configuration:

- Uplink-1 (VLAN 100): 192.168.100.0/24 -> router R1 at 192.168.100.1
- Uplink-2 (VLAN 101): 192.168.101.0/24 -> router R2 at 192.168.101.1
- A static route for 10.100.0.0/16 was added with both next-hops (192.168.100.1 and 192.168.101.1).
- The Scope of this route is set to Uplink-1.

Symptoms:

- Virtual Machines (VMs) cannot reach 10.100.0.0/16.
- Traceroute from the VM stops at the Tier-0 gateway with "Destination Net Unreachable"
- Pings from the Edge nodes to both 192.168.100.1 and 192.168.101.1 are success.

What explains why workloads in NSX cannot reach the external network?

A.

Static routes do not support Equal Cost Multi-Pathing (ECMP) in NSX.

B.

The static route Scope is set to only one uplink interface, but the next-hops are on two different VLANs.

C.

The next-hops should have been configured as the Tier-0's own uplink IPs instead of the routers IPs.

D.

The physical routers are missing return routes.

Question 7
Single choice

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?

A.

The Tier-0 Gateway route map must contain an IP prefix with only a deny rule.

B.

The Tier-0 Gateway must be configured in Non-Preemptive failover mode.

C.

The Tier-0 Gateway must be configured in Active/Standby mode.

D.

The Tier-0 Gateway must have IPv6 enabled.

Question 8
Single choice

An administrator has a standalone vSphere 8.0 Update 1a deployment that is running with VMware NSX 4.1.0.2 and has to converge the deployment into a new VMware Cloud Foundation (VCF) instance.

How can the administrator accomplish this task?

A.

Manually upgrade both vSphere and NSX to version 9 prior to converging. Then use the VCF Installer to converge the vSphere 9 and NSX 9 instances into a new VCF management domain.

B.

Manually upgrade vSphere to version 9. Then use the VCF Installer to converge the vSphere 9 environment into a new VCF management domain. Then use the VCF lifecycle management tools to upgrade NSX to version 9.

C.

Use the VCF Installer to converge the existing vSphere 8 and NSX 4 environment into a new VCF management domain. Then use the VCF lifecycle management tools to upgrade to 9.

D.

Manually upgrade vSphere to version 9 and uninstall NSX 4. Then use the VCF Installer to converge the vSphere 9.0 environment into a new VCF management domain at which time NSX 9 will be reinstalled.

Question 9
Single choice

The administrator is implementing a multi-location VMware Cloud Foundation (VCF) environment. The design requires centralized security and networking policies across multiple VCF instances.

What action must the administrator take to satisfy the requirements?

A.

Deploy a Global Manager cluster manually.

B.

Deploy a Local Manager (LM) cluster using VCF Operations.

C.

Use SDDC Manager to deploy a Global Manager cluster.

D.

Use VCF Installer to deploy a Local Manager (LM) cluster.

Question 10
Single choice

An administrator has a VMware Cloud Foundation (VCF) instance. A critical NSX security update has been released by Broadcom.

How can the administrator install the NSX update?

A.

Download the NSX patch to the NSX Manager. Apply it using VCF Operations Fleet Management.

B.

Download the NSX patch to VCF Operations. Apply it using NSX Manager.
