• Question 285:

  Why does a router create an ASBRSum (Type 4) LSA?

  A. An ABR creates an ASBRSum (Type 4) LSA with the information contained in NSSA (Type 7) LSAs it receives from NSSAs.

  B. An ABR creates an ASBRSum (Type 4) LSA to describe the router ID of ASBRs located in other areas.

  C. An ASBR creates an ASBRSum (Type 4) LSA to describe its router ID so that routers in other areas can reach the external networks it advertises.

  D. An ABR creates an ASBRSum (Type 4) LSA to summarize routes received from other areas.

  Correct Answer: B

• Question 286:

  ON NO: 207

  A. control-plane state

  B. link-state protocol adjacencies

  C. interface and kernel information

  D. BGP peering relationships

  Correct Answer: C

• Question 287:

  You want to configure a redundant trunk group on a switch. You want ge-0/0/0.0 to be the default link; however, if ge-0/0/0.0 fails and the switch begins using ge-0/0/1.0, you want the switch to continue using ge-0/0/1.0 until ge-0/0/1.0 fails. Which configuration will accomplish this scenario?

  A. redundant-trunk-group { interface ge-0/0/0.0 { primary; } interface ge-0/0/1.0 { primary; } }

  B. redundant-trunk-group { interface ge-0/0/0.0; interface ge-0/0/1.0; no-preempt; }

  C. redundant-trunk-group { interface ge-0/0/0.0 { primary; } interface ge-0/0/1.0; }

  D. redundant-trunk-group { interface ge-0/0/0.0; interface ge-0/0/1.0; }

  Correct Answer: D

• Question 288:

  Which two statements are true of IS-IS? (Choose two.)

  A. When configured on a broadcast segment, IS-IS elects a designated intermediate system that establishes adjacencies with all IS-IS enabled nodes on the segment.

  B. When configured on a broadcast segment, IS-IS forms a full mesh of adjacencies called a mesh group; unlike OSPF, no designated device exists to represent the segment.

  C. When configured on a broadcast segment, IS-IS elects a backup designated intermediate system.

  D. When configured on a broadcast segment, the network itself is called a pseudo-node

  Correct Answer: AD

• Question 289:

  You want to ensure that all traffic arriving on interface fe-0/0/0.0 will be routed to next-hop 10.1.1.1, regardless of the more specific routes that might appear in the routing table. How can you accomplish this configuration?

  A. Configure a default route with a next hop of 10.1.1.1 and configure the always-use flag for the route.

  B. Configure and apply a firewall filter that sends all traffic to a routing instance, configure a default route in that routing instance, and configure the router to install interface routes in that routing instance.

  C. Configure a routing policy that matches all traffic and sets the next hop to 10.1.1.1, and configure a RIB group to ensure that the routing policy can resolve the next hop to 10.1.1.1.

  D. Configure a firewall filter that matches all traffic and sets the next hop to 10.1.1.1, apply the firewall filter to a RIB group, and assign the fe-0/0/0.0 interface to that RIB group.

  Correct Answer: B

• Question 290:

  A. DR:R3 BDR: R4

  B. DR: R4 BDR: R3

  C. DR: R6 BDR: R1

  D. DR: R6 BDR: R2

  Correct Answer: D
