  1. Issue the eigrp stub command on R1.

  2. Issue the no eigrp stub command on R1.

  3. Issue the eigrp stub command on R2.

  4. Issue the no eigrp stub command on R2.

Correct Answer: B

Question No.2

R2 has a locally originated prefix 192.168.130.0/24 and has these configurations:

What is the result when the route-map OUT command is applied toward an eBGP neighbor R1 (1.1.1.1) by using the neighbor 1.1.1.1 route-map OUT out command?

  1. R1 sees 192.168.130.0/24 as two AS hops away instead of one AS hop away.

  2. R1 does not accept any routes other than 192.168.130.0/24

  3. R1 does not forward traffic that is destined for 192.168.30.0/24

  4. Network 192.168.130.0/24 is not allowed in the R1 table

Correct Answer: A

Question No.3

Question No.4

  1. nonbroadcast multiaccess

  2. packet switching

  3. policy-based routing

  4. forwarding information base

Correct Answer: C

Question No.5

Refer to the exhibit. The output of the trace route from R5 shows a loop in the network. Which configuration prevents this loop?

B.

C.

D.

Correct Answer: A

Question No.6

Refer to the exhibit. An engineer configures a static route on a router, but when the engineer checks the route to the destination, a different next hop is chosen. What is the reason for this?

image

  1. Dynamic routing protocols always have priority over static routes.

  2. The metric of the OSPF route is lower than the metric of the static route.

  3. The configured AD for the static route is higher than the AD of OSPF.

  4. The syntax of the static route is not valid, so the route is not considered.

Correct Answer: C

Question No.7

Refer to the exhibit. An engineer is trying to generate a summary route in OSPF for network 10.0.0.0/8, but the summary route does not show up in the routing table. Why is the summary route missing?

image

  1. The summary-address command is used only for summarizing prefixes between areas.

  2. The summary route is visible only in the OSPF database, not in the routing table.

  3. There is no route for a subnet inside 10.0.0.0/8, so the summary route is not generated.

  4. The summary route is not visible on this router, but it is visible on other OSPF routers in the same area.

Correct Answer: C

Question No.8

Refer to the exhibit. An engineer is trying to block the route to 192.168.2.2 from the routing table by using the configuration that is shown. The route is still present in the routing table as an OSPF route. Which action blocks the route?

image

  1. Use an extended access list instead of a standard access list.

  2. Change sequence 10 in the route-map command from permit to deny.

  3. Use a prefix list instead of an access list in the route map.

  4. Add this statement to the route map: route-map RM-OSPF-DL deny 20.

Correct Answer: B

Question No.9

What is a prerequisite for configuring BFD?

  1. Jumbo frame support must be configured on the router that is using BFD.

  2. All routers in the path between two BFD endpoints must have BFD enabled.

  3. Cisco Express Forwarding must be enabled on all participating BFD endpoints.

  4. To use BFD with BGP, the timers 3 9 command must first be configured in the BGP routing process.

Correct Answer: C

Question No.10

Refer to the exhibit. R2 is a route reflector, and R1 and R3 are route reflector clients. The route reflector learns the route to 172.16.25.0/24 from R1, but it does not advertise to R3. What is the reason the route is not advertised?

image

  1. R2 does not have a route to the next hop, so R2 does not advertise the prefix to other clients.

  2. Route reflector setup requires full IBGP mesh between the routers.

  3. In route reflector setup, only classful prefixes are advertised to other clients.

  4. In route reflector setups, prefixes are not advertised from one client to another.
