Question 1:
Refer to the exhibit.
Company A established BGP sessions with several ISPs. A network engineer at the company must filter out all traffic except for routes that transit AS 152.

Which action resolves the issue?
A. Add a second filtering policy in the format ip access-list 1 permit ^152_([0-9]+).
B. Add a second filtering policy in the format ip prefix-list 1 permit ^152^.
C. Change the filtering policy to ip explicit-path 1 permit $152^.
D. Change the filtering policy to ip as-path access-list 1 permit _152_.
Correct Answer: A
Question 2:

A. They hold IPv4 or IPv6 prefixes that do not match specifications.
B. They hold IPv4 or IPv6 prefix match specifications.
C. They hold IPv6 prefix match specifications.
D. They hold IPv4 prefixes that do not match specifications.
Correct Answer: B
Question 3:
Refer to the exhibit. Routers RA and RB are IS-IS peers configured for NSF, but router RC is an IS-IS peer without NSF capability. If RA undergoes processor switchover, what is the effect on the network environment?
A. If RC is operating without the Cisco configuration option, only 2 routers tear down their peering relationships and re-establish peering
B. All peer relationships remain up, but the link-state database is rebuild on each device
C. If RC is operating without the Cisco configuration option, all three routers tear down their peering relationships and re-establish peering
D. All peer relationships remain up and the link-state database is unchanged
Correct Answer: B
Question 4:
What is the role of a segment routing mapping server?
A. It advertises a local SID mapping policy to all of the mapping clients
B. It works with IGP instances to calculate the prefix-SIDs in the absence of a mapping policy
C. It selects multiple mapping entries to create overlapping active mapping policies
D. It reads and translates remotely received SIDs from other mapping servers to create SID mapping entries
Correct Answer: A
Question 5:
What is the purpose of a BGP confederation?
A. It limits the number of routes a device receives from its peers, which reduces CPU load.
B. It improves service by increasing the number of simultaneous iBGP peering sessions.
C. It redirects traffic away from route reflectors, which reduces their operating load.
D. It reduces the number of iBGP peers and increases stability.
Correct Answer: D
Question 6:
Refer to the exhibit.
R1 is directly connected to R2 and R3. R1 is in BGP AS 123, R2 is in BGP AS 2, and R3 is in BGP AS 3. Assume that there is no connectivity issue between R1, R2 and R1, R3. Which result between BGP peers R1, R2 and R1, R3 is true?
A. The BGP session does not come up between R1 and R2 and between R1 and R3.
B. The BGP session comes up between R1 and R2 and between R1 and R3.
C. The BGP session comes up between R1 and R3, but not between R1 and R2.
D. The BGP session comes up between R1 and R2, but not between R1 and R3.
Correct Answer: B
Question 7:
Refer to the exhibit.
Router 1 is a core ABR in a Cisco Unified MPLS environment. All of the router 1 BGP peers are established, but traffic between customers is failing. Which BGP configuration must be added to the configuration?
A. It must be configured for graceful restart
B. It must be configured with a route reflector
C. It must be configured with send labels
D. It must be configured with PIC edge
Correct Answer: C
Question 8:
Refer to the exhibit.
An engineer has successfully fixed BGP peering issue. R1 has an established eBGP peering with R2 and R3. Which mechanism should the engineer apply in order to steer the traffic correctly?
A. The MED attribute can be applied on R2 to influence R1 to use it as the primary path.
B. The local preference attribute can be applied on R3 to influence AS 65513 to use AS 65515 as the secondary path.
C. The weight attribute can be applied on R2 to influence AS 65513 to use AS 65515 as the primary path.
D. The IGP metric can be manipulated on R1 to allow traffic to be load balanced between R2 and R3.
Correct Answer: D
Explanation:
Some level of load balancing is achieved by default as BGP prefers shortest AS_PATH for certain prefix (Cisco BGP path selection algorithm – rule 4) . If 1-7 rules gives no preference for certain prefix then with rule 8. Prefer lowest IGP metric to BGP next hop we can force traffic to R2 or R3 influencing load distribution.
Question 9:
Refer to the exhibit.
A network operator is troubleshooting TE tunnels and discovers that the soft preemption is not working as desired. Where should the soft preemption be applied to solve the issue?
A. on the tail-end device for tunnel-te1 192.168.0.7
B. under the tunnel-te1 interface on PE1
C. explicitly for tunnel-te 1 under the Cisco MPLS TE configuration mode after the timeout setting
D. Under the interface Loopback0 necessary for this deployment type.
Correct Answer: B
Question 10:
Refer to the exhibit.
A network engineer is investigating a report of packet drops in an application running on a server connected to PE2. The engineer determined that:
1.
The OSPF adjacency in area 0 is up, and it is learning the loopback addresses of all routers in area 0.
2.
Traffic from users connected to PE1 to the application is also passing normally.
3.
Packets from PE2 back to PE1 are being dropped.
Which action resolves the issue?

Correct Answer: C
Question 11:
The UserA device fails to receive IPTV streaming traffic from the source. While debugging the issue, a network engineer finds that routers RB and RC receive the multicast traffic normally. RC receives subscription messages from UserA to join the IPTV stream. Which action must the engineer take on router RA to correct this problem?

B. To support fast convergence, OSPF uses the LSA arrival timer and IS-IS uses the PRC-interval timer.
C. IS-IS supports ordinary, stub, totally-stub, and NSSA areas, but OSPF supports only stub areas.
D. IS-IS links are associated with either a Level 1 area or a Level 2 area at one time, but OSPF links are associated with multiple areas at one time.
