• Question 212:

  Customer XYZ network consists of an MPLS core. IS-IS running as IGP a pair of BGP route reflectors for route propagation, and a few dozens of MPLS-TE tunnels for specific tactical traffic engineering requirements. The customer's engineering department has some questions about the use of the Overload Bit in the IS-IS networks and how it could be used to improve their current network design. Which two concepts about the Overload Bit are true? (Choose two.)

  A. It can be set on a router during the startup process for a fixed period of time
  B. Networks advertised within the LSPs of the respective node will become unreachable
  C. It forces the midpoint MPLS-TE node to reoptimize the primary tunnels going through the OL node.
  D. It can be set on a router until other interacting protocols have signaled convergence.
  E. It is not recommended on BGP Route Reflectors
  A. It can be set on a router during the startup process for a fixed period of time
  D. It can be set on a router until other interacting protocols have signaled convergence.

• Question 213:

  A service provider recently migrated to an SD-WAN solution for delivering WAN connections to its customers. One of the main challenges with the SD-WAN deployment is that branch site volume increases every year, which causes

  management complexity.

  Which action resolves the issue?

  A. Implement a scalable network management system to manage all sites.
  B. Adopt a well-structured SD-WAN service management lifecycle model
  C. Build a service orchestration platform on top of the network controller
  D. Set up a dedicated team to monitor and provision new customers
  B. Adopt a well-structured SD-WAN service management lifecycle model

• Question 214:

  Which two statements describe the functionality of OSPF packet-pacing timers? (Choose two )

  A. The group-pacing timer controls the interval that is used for group and individual LSA refreshment
  B. OSPF flood-pacing timers allow dynamic control of the OSPF transmission queue size
  C. OSPF retransmission-pacing timers allow control of packet interleaving between nonconsecutive link-state update packets in the OSPF retransmission queue.
  D. OSPF flood-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF transmission queue.
  E. OSPF retransmission-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF retransmission queue.
  D. OSPF flood-pacing timers allow control of interpacket spacing between consecutive link-state update packets in the OSPF transmission queue.

• Question 217:

  Company XYZ is connecting its sites over a private WAN The company is planning on implementing multicast routing on the network.

• Question 218:

  Refer to the exhibit.

  

  Two data center siles X and Y are connected with a direct backdoor link with these conditions

  1.Site-specific firewalls are deployed behind the Internet edge routers R1 and R2.

  2.Both sites are advertising the address pool 100 75 10 0/23 toward the internet Site-X finds that Internet traffic returning from user PCs comes back on the Site-Y link Which design resolves the issue?

  A. Use BGP MED to influence Site-X return traffic Change the IP address scheme of both sites.
  B. Change the Site-Y firewall configuration to replicate the Site-X configuration. Advertise the low MED attribute on Site-X to the Internet.
  C. Add a static route toward the Internet on Site-X. Change the DNS policy on Site-Y to block traffic.
  D. Establish control plane peering between edge routers. Have Site-X advertise an IP pool with a longer prefix.
  A. Use BGP MED to influence Site-X return traffic Change the IP address scheme of both sites.

• Question 219:
