  C. OTV

  D. AToM

  Correct Answer: C

• Question 413:

  What are two valid reasons for aggregating routing information within a network? (Choose two.)

  A. to reduce the size of the output of various show commands

  B. to reduce the impact of topology changes

  C. to reduce the amount of information any specific router within the network must store and process

  D. to improve optimal routing within the network

  E. to isolate the impact of DDoS attacks

  Correct Answer: BC

• Question 414:

  The IGP next-hop reachability for a BGP route is lost but a default route is available. Assuming that BGP connectivity is maintained, what will happen to the BGP route?

  A. It will be removed from the BGP table.

  B. It will be considered invalid for traffic forwarding.

  C. It will be considered a valid route.

  D. It will be put in a hold-down state by BGP until the next hop has been updated.

  Correct Answer: C

• Question 415:

  A Tier-3 Service Provider is evolving into a Tier-2 Service Provider due to the amount of Enterprise business it is receiving. The network engineers are re-evaluating their IP/MPLS design considerations in order to support duplicate/ overlapping IP addressing from their Enterprise customers within each Layer 3 VPN. Which of the following would need to be reviewed to ensure stability in their network?

  A. Assigning unique Route Target ID's

  B. Assigning unique Route Distinguishers

  C. Assigning unique IP address space for the Enterprise NAT/Firewalls

  D. Assigning unique VRF ID's to each Layer 3 VPN

  Correct Answer: B

• Question 416:

  An IS-IS router is connected to four links and redistributing 75 routes from RIP.

  How many LSPs will this router originate?

  A. one LSP: containing the router information, internal routes, and external routes

  B. two LSPs: one containing router information and internal routes and one containing external routes

  C. three LSPs: one containing all links, one containing router information, and one containing external routing information

  D. six LSPs: one for each link, one containing router information, and one containing external routing information

  Correct Answer: A

• Question 417:

  A company wants to use SSM as the multicast routing protocol inside its network. Some of its multicast applications do not support IGMPv3. In which two ways can the mapping be done when these applications send IGMPv2 join messages? (Choose two.)

  A. The Layer 2 switches can send a request to a DNS server.

  B. The Layer 3 multicast routers can send a request to a DNS server.

  C. The mapping can be done statically at the Layer 2 switches.

  D. The mapping can be done statically at the Layer 3 multicast routers.

  E. The Layer 2 switches can transform the IGMPv2 join to an IGMPv3lite join.

  F. The Layer 3 multicast routers can transform the IGMPv2 join to an IGMPv3lite join.

  Correct Answer: BD

• Question 418:

  Why should IGP advertisements be disabled on an access link where a host is attached?

  A. because hosts do not run routing protocols

  B. to prevent the injection of bad routes

  C. to reduce router overhead

  D. because edge hosts are statically routed

  Correct Answer: B

• Question 419:

  Refer to the exhibit.

  

  This Layer 2 ring has 10 VLANs with 1000 MAC addresses in each VLAN. Which protocol or mechanism provides the shortest traffic outage if the link marked with "X" fails?

  A. PVRST

  B. REP

  C. MST

  D. G.8031

  E. BFD

  Correct Answer: B

• Question 420:

  Refer to the exhibit.

  

  A new IPv4 multicast-based video-streaming service is being provisioned. During the design-validation tests, you realize that the link between the two buildings is carrying multicast traffic even when there are no receivers connected to the switch in Building B and despite IGMP snooping being enabled on both Layer 2 switches and IGMPv2 runs on the hosts. Which design change will prevent the multicast traffic from being unnecessarily flooded throughout the campus network?

  A. Enable PIM snooping on both Layer 2 switches.

  B. Enable multicast storm control on the link between Switch 1 and Switch 2.

  C. Use static Layer 2 MAC forwarding entries on Switch 1.

  D. Change the IPv4 multicast group address such that it excludes the usage of link-local MAC addresses.

  E. Ensure that Switch 1 is an IGMP querier.

  Correct Answer: D
