Refer to the exhibit.

An architect must design a solution to connect bank site A with bank site B and support:
- network operation center monitoring end-to-end L3VPN and L2VPN traffic
- company adding thousands of routes in the next two years

Which two BGP solutions must the design include? (Choose two.)

  1. Establish full mesh IBGP peering with all routers in different IGP domains.
  2. Redistribute different IGP domain routes in a BGP IPv4 routing instance.
  3. Connect multiple IGP/LDP domains using a BGP IPv4 unicast family on the ABR.
  4. Apply BGP policies on all routers to filter out ABR and PE loopback IP addresses.
  5. Transport site routes using a BGP VPNv4 address family on the PE routers.

Answer(s): C,E



Refer to the exhibit.



An engineer must design an address translation solution to provide internet connectivity for the corporate network. The design is restricted to the 172.16.168.0/22 subnet. Which solution must the engineer choose?

  1. stateful NAT66
  2. stateless NAT64
  3. stateless NAT66
  4. stateful NAT64

Answer(s): D





Refer to the exhibit. A network engineer must design a BGP solution based on:

- The route reflector must have one or more direct physical connections to the core routers (R3 and R4).
- The route reflector must have full redundancy and avoid a single point of failure.
- R2 to R1 link utilization is 90%, and the remaining links are less than 50% utilized.

Which two solutions must the design include? (Choose two.)

  1. Configure R1 to be a client of R2 and R4.
  2. Configure R5 to be a client of R3 and R4
  3. Configure R2 to be a client of R1 and R4.
  4. Configure R3 to be a client of R2 and R4.
  5. Configure R4 to be a client of R1 and R3.

Answer(s): D,E



Refer to the exhibit.



An engineer is designing a redistribution solution for a customer. The customer recently acquired another company and decided to Integrate the new network running RIPv1 with the company's existing network. Which redistribution technique must the engineer select to ensure the multipoint two-way redistribution does not cause routing loops?

  1. distribute-lists inbound under the EIGRP process denying RIPv1 learned prefixes
  2. distribute-lists inbound under the RIPv1 process denying EIGRP learned prefixes
  3. distribute-lists outbound under the EIGRP process denying RIPv1 learned prefixes
  4. distribute-lists outbound under the RIPv1 process denying EIGRP learned prefixes

Answer(s): A





Refer to the exhibit. A network engineer with an employee ID: 4433:77:420 must design a BGP solution based on these conditions:

- Traffic sessions occur between the branches and the data center.
- Branch B has limited resources to process routing updates.
- HQ must filter out all prefixes from branch A to R4.

Which outbound route filtering (ORF) solution must the engineer choose?

  1. Use a prefix list with the 10.10.10.0/24 subnet for ORF on R5.
  2. Use a prefix list with the 10.10.10.0/24 subnet for ORF on R2
  3. Use a prefix list with the 192.168.10.0/24 subnet for ORF on R2.
  4. Use a prefix list with the 192.168.10.0/24 subnet for ORF on R4.

Answer(s): B
