A network engineer is configuring an SNMP community on router RB with these requirements:
Allow read-only access for all objects to members of Access-List 10 that use the comaccess community string.
Other SNMP managers must not have access to objects.
SNMP authentication failure traps must be sent to SNMPv2c and then to the host using SNMPv2c with the public community string.
Which configuration meets these requirements?

1. A. Option A
2. B. Option B
3. C. Option C
4. D. Option D

Correct Answer: A

Which role does the Adjacency-SID sub-TLV extension perform in the IS-IS routing protocol?

1. A. It is advertised within a TLV-24 (IS-IS Neighbor Adjacency Attribute) to label a specific adjacency between Level1 routers within one IS-IS area.
2. B. It is advertised within TLV-136 (Extended IP Reachability) to label a specific node n the network.
3. C. It is advertised within TLV-22 (Extended IS Reachability) to label a specific link in a segment routing domain.
4. D. It is advertised within TLV-145 (IS-IS Prefix Reachability Information) to label host prefixes on loopback interfaces on Level 2 routers within one

Correct Answer: C

BGP has been implemented on a IOS XR router. Which configuration sends BGP IPv4 labels to build inter-domain LSPs?

1. A. router bgp 65515 address-family ipv4 unicast neighbor 172.16.70.23 send-community extended
2. B. router bgp 65515 no bgp default ipv4-unicast
3. C. router bgp 65515 address-family ipv4 unicast neighbor 172.16.70.23 send-community
4. D. router bgp 65515 neighbor 172.16.70.23 address-family ipv4 labeled-unicast

Correct Answer: D

Why do Cisco MPLS TE tunnels require a link-state routing protocol?

1. A. Link-state routing protocols use SPF calculations that the tunnel endpoints leverage to implement the tunnel
2. B. The link-state database provides a data repository from which the tunnel endpoints can dynamically select a source ID
3. C. The tunnel endpoints can use the link-state database to evaluate the entire topology and determine the best path
4. D. The link state database provides segmentation by area, which improves the path-selection process

Correct Answer: C

Refer to the exhibit.

Tier 1 ISP A is connected to small Tier 3 ISP B. The EBGP routing protocol is used for route exchange. The networking team at ISP A noticed the flapping of BGP sessions with ISP B. The team decides to Improve stability on the network by suppressing the subnet for 30 minutes when a session begins to flap. Which action must the team perform to meet this goal?

1. A. Implement a BGP route-penalty timer on ISP A router R1 with the bgp penalty-timer 30 250 750 15 command.
2. B. Implement BGP route dampening on ISP A router R1 with the bgp dampening 15 700 1500 30 command.
3. C. Implement BGP route suppression on ISP A router R2 with the bgp suppression 30 600 1200 30 command.
4. D. Implement a BGP route withdraw-delay timer on ISP B router R3 with the bgp withdraw-delay 30 15 90 30 command.

Correct Answer: B
