  A. On the VPC default route advertiser
  B. On the VPC's Transit Gateway
  C. On the providers' BGP peer template
  D. On the VPC Gateway Firewall
  B. On the VPC's Transit Gateway

• Question 24:

  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?

  A. On each segment default gateway.
  B. On the Tier-1 gateway.
  C. On the VPC transit gateway.
  D. On the provider Tier-0 neighbor.
  C. On the VPC transit gateway.

• Question 25:

  Which of the following statements is true when configuring Remote Tunnel End Points (RTEPs) with NSX Federation?

  A. TEP and RTEP networks must use separate physical NICs.
  B. RTEP needs to be configured on only one edge node.
  C. The default MTU for the RTEP network is 1500.
  D. DHCP must be used to assign IP addresses to the RTEP.
  C. The default MTU for the RTEP network is 1500.

• Question 26:

  The administrator must configure Border Gateway Protocol (BGP) on the Tier-0 Gateway to establish neighbor relationships with upstream routers.

  Which two statements describe the Border Gateway Routing Protocol (BGP) configuration on a Tier-0 Gateway? (Choose two.)

  A. EIGRP is configured by default.
  B. Can be used as an Exterior Gateway Protocol.
  C. The network is divided into areas that are logical groups.
  D. It supports a 4-byte autonomous system number.
  B. Can be used as an Exterior Gateway Protocol.
  D. It supports a 4-byte autonomous system number.

• Question 27:

  An administrator is tasked to enable users to configure an individual VPC, but not create subnets.

  What three NSX roles would the administrator assign to allow access without the ability to create subnets? (Choose three.)

  A. Security Admin
  B. Network Admin
  C. VPC Admin
  D. Security Operator
  E. Network Operator
  C. VPC Admin
  D. Security Operator
  E. Network Operator

• Question 28:

  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?

  A. BFD timers are mismatched between Tier-0 Gateway and the upstream routers.
  B. The MTU does not match on the end-to-end between Tier-0 Gateway and upstream routers.
  C. BFD is configured in echo mode on the upstream routers.
  D. The Edge nodes are undersized and are experiencing high contention on CPU and drops BFD packets.
  B. The MTU does not match on the end-to-end between Tier-0 Gateway and upstream routers.

• Question 29:

  An administrator is troubleshooting an issue where workloads connected to a Tier-1 Gateway named T1- App can no longer reach external North/South destinations.

  - The Tier-1 is connected to an Active/Standby Tier-0 Gateway named T0-Prod.

  Symptoms observed:

  - VMs on segments attached to T1-App can ping each other.

  - VMs on T1-App cannot reach any external IP outside T0-Prod.

  - From a VM on the segment, ping to the T1-App Distributed Router (DR) IP succeeds.

  - Ping from the VM to the T1-App Service Router (SR) fails.

  - The Edge cluster hosting the T1-App SR shows both Edge nodes Up and Healthy.

  - No failover has occurred - the same Edge node is still shown as Active for T1-App.

  What is the most likely cause of this issue?

  A. The overlay network between DR and SR has an MTU mismatch.
  B. Route advertisement from T1-App to T0-Prod for 100.64.x.x/31 is disabled.
  C. Static default route is missing on the Tier-1 DR component.
  D. Localized control plane is enabled on the Tier-1 causing the SR to remain admin-down.
  A. The overlay network between DR and SR has an MTU mismatch.

• Question 30:

  A VMware Cloud Foundation private cloud design must exchange routes between NSX overlay networks and the physical data center routing domain. The design should keep the external routing boundary at the provider edge instead of placing it on individual workload segments.

  Which NSX component should provide this north-south routing boundary?

  A. A Tier-0 gateway backed by an Edge cluster
  B. A Tier-1 gateway configured only for distributed routing
  C. An overlay segment with no upstream gateway
  D. A transport node profile assigned to each ESXi host
  A. A Tier-0 gateway backed by an Edge cluster
