  2. RSTP
  3. Rapid PVST
  4. STP

A network engineer must segregate three interconnected campus networks using IS-IS routing. A two-layer hierarchy must be used to support large routing domains and to avoid more specific routes from each campus network being advertised to other campus network routers automatically. Which two actions does the engineer take to accomplish this segregation? (Choose two.)

  1. Designate two IS-IS routers as BDR routers at the edge of each campus, and configure one BDR for all Level 1 routers and one BDR for all Level 2 routers.
  2. Designate two IS-IS routers from each campus to act as Level 1/Level 2 backbone routers at the edge of each campus network.
  3. Assign the same IS-IS NET value for each campus, and configure internal campus routers with Level 1/ Level 2 routing.
  4. Utilize different MTU values for each campus network segment. Level 2 backbone routers must utilize a larger MTU size of 9216.
  5. Assign a unique IS-IS NET value for each campus, and configure internal campus routers with Level 1 routing.

Answer(s): B,E



Which consideration must be taken into account when using the DHCP relay feature in a Cisco SD-Access Architecture?

  1. DHCP-relay must be enabled on fabric edge nodes to provide the correct mapping of DHCP scope to the local anycast gateway.
  2. A DHCP server must be enabled on the border nodes to allow subnets to span multiple fabric edges.
  3. DHCP servers must support Cisco SD-Access extensions to correctly assign IPs to endpoints in an SD- Access fabric with anycast gateway.
  4. DHCP Option-82 must be enabled to map the circuit IP option to the access fabric node where the DHCP discover originated.

Answer(s): A
