  • A. Split the network into two separate ASs.
  • B. Exchange all routes between locations.
  • C. Summarize the routes between the hubs.
  • D. Make each spoke site router a stub router.
  • E. Summarize the routes from spokes to the hubs.

Question 5

An engineer must design a solution to connect a customer to the Internet. The solution will include a Layer 3 circuit with a CIR of 50 Mbps from the service provider. The hand-off from the provider's switch to the customer's router is 1Gbps. Which solution should the engineer include to prevent potential issues with choppy voice traffic?

  • A. Reduce the bandwidth of the connection to the router.
  • B. Implement hierarchical QoS with a parent policing policy.
  • C. Implement hierarchical QoS with a parent shaping policy.
  • D. Add a bandwidth statement to the router interface.

Question 8

An engineer is designing a campus network with Cisco Catalyst 9500 switches in the aggregation layer. The design requires running nonblocking Layer 2 MEC from the aggregation layer to the access layer. The Catalyst switches are located on different campus floors for availability reasons, and each access switch will contain a single VLAN. Which technology must the engineer choose for the aggregation switches in the design?

  • A. VSS
  • B. StackWise-480
  • C. VPC
  • D. StackWise Virtual

Question 9

An engineer is designing a BGP network for a large customer. To permit efficient scaling, the BGP domain is split into clusters. Which peering solution should be used between the route reflectors in different clusters for the BGP routes to be propagated appropriately?

  • A. The route reflectors should be made dents of each other.
  • B. The route reflectors should be nonclients with regards to each other.
  • C. The route reflectors should not have any kind of BGP peering.
  • D. The route reflectors should have peering through another nonclient router.
