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?

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

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

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

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

A network engineer is investigating a flapping (up/down) interface issue on a core switch that is synchronized to an NTP server. Log output currently does not show the time of the flap. Which command allows the logging on the switch to show the time of the flap according to the clock on the device?

A. service timestamps log uptime

B. clock summer-time mst recurring 2 Sunday mar 2:00 1 Sunday nov 2:00

C. service timestamps log datetime localtime show-timezone

D. clock calendar-valid

You have configured OSPF on your network and enabled route summarization on an area border router (ABR) with the following command:

Router(config-router)# area 3 range 165.164.8.0 255.255.248.0

What does the 3 specify in this command?

A. The ID of the OSPF backbone

B. The number of networks summarized in the area

C. The ID of the area about which routes will be summarized

D. The ID of the area to which the summary route information will be sent

You instructed your assistant to configure redistribution of OSPF routes into EIGRP on Router 9. The routes are not being advertised to EIGRP and you are troubleshooting the problem. The EIGRP process ID is 100 and the OSPF process ID is 20. When you ask your assistant what commands were executed, you are shown the following:

Router9(config)# router eigrp 100 Router9(config-router)# redistribute ospf 20

What is the problem?

A. no metric was configured

B. the process IDs are incorrect

C. the redistribute command is executed at the interface configuration prompt

D. the redistribute command is executed at the global configuration prompt

An engineer creates a Cisco DNA Center cluster with three nodes, but all the services are running on one host node. Which action resolves this issue?

B. Click the master host node with all the services and select services to be moved to other hosts

C. Enable service distribution from the Systems 360 page.

D. Click system updates, and upgrade to the latest version of Cisco DNA Center.

Refer to the exhibit.

The network administrator configured the Chicago router to mutually redistribute the LA and NewYork routes with OSPF routes to be summarized as a single route in EIGRP using the longest summary mask:

After the configuration, the New York router receives all the specific LA routes but the summary route. Which set of configurations resolves the issue on the Chicago router?

A. Option A

B. Option B

C. Option C

D. Option D

Refer to the exhibit A company builds WAN infrastructure between the head office and POPs using DMVPN hub-and-spoke topology to provide end-to-end communication All POPs must maintain point-to-point connectivity with the head office Which configuration meets the requirement at routers R12 and R13?

A. Option A

B. Option B

C. Option C

D. Option D

Refer to the exhibit.

Which configuration resolves the IP SLA issue from R1 to the server?

C. R6(config)#ip sla 650 R6(config-ip-sla)ff udp-jitter 10.60.60.6

D. R6(config)#ip sla schedule 10 life forever start-time now

Topology

Tasks

A company is connected to an ISP and some of the networks between the ISP and the company are not reachable. Troubleshoot and resolve the issues to achieve these goals:

1.

A single /16 is advertised for all infrastructure-connected interfaces that belong to the 10.20.x.x network using BGP network commands from border routers connected to the ISP. Configuration modification is allowed in R4 and R5 to achieve the results. Do not use the BGP aggregate command.

2.

R6 receives the ISP R2 Loopback2 from R4 and receives a summary address for both Loopbacks of ISP R2 from R4 or R5. Use BGP attribute local-preference, add , for example, for R6, use “default+6 = value to be used”. Use the existing prefix lists or route maps with the sequence numbering starting at 10 and added in increments of 10.

3.

R6 receives the ISP R2 Loopback1 from R5 and receives a summary address for both Loopbacks of ISP R2 from R4 or R5 using the same guidelines.

4.

R6 advertises its Loopback1 /24 address through BGP.

A. See the solution below in Explanation.
