The engineering team wants to limit control traffic on router RX with the following IP address assignments:
• Accepted traffic for router: 10.0.0.0/24
• NOC users IP allocation: 192.168.10.0/24
Which additional configuration must be applied to RX to apply the policy for MSDP?

1. A. RX(config)#access-list 151 permit tcp any gt 1024 10.10.0.0 0.0.0.255 eq 639RX(config)#access-list 151 permit tcp any eq 639 10.10.0.0 0.0.0.255 gt 1024 established
2. B. RX(config)#access-list 150 permit tcp any gt 1024 10.0.0.0 0.0.0.255 eq 639RX(config)#access-list 150 permit tcp any eq 639 10.0.0.0 0.0.0.255 gt 1024 established
3. C. RX(config)#access-list 151 permit tcp any 10.0.0.0 0.0.0.255 eq 639RX(config)#access-list 151 permit udp any 10.0.0.0 0.0.0.255 eq 639
4. D. RX(config)#access-list 150 permit tcp any 10.0.0.0 0.0.0.255 eq 639RX(config)#access-list 150 permit udp any 10.0.0.0 0.0.0.255 eq 639

Correct Answer: B

The CE router is peering with both PE routers and advertising a public prefix to the internet. Routing to and from this prefix will be asymmetric under certain network conditions, but packets must not be discarded. Which configuration must an engineer apply to the two PE routers so that they validate reverse packet forwarding for packets entering their Gi2 interfaces and drop traffic from the RFC1918 space?

1. A. ip verify unicast source reachable-via rx allow-default
2. B. interface GigabitEthernet 2ip verify unicast source reachable-via rx
3. C. ip verify unicast source reachable-via any allow-default interface GigabitEthernet 2
4. D. ip verify unicast source reachable-via any

Correct Answer: D

Refer to the exhibit.

An engineer started to configure a router for OSPF. Which configuration must the engineer perform on the router without changing any interface configuration so that the router establishes an OSPF neighbor relationship with its peer?

1. A. router(config)# router ospf 11router(config-if)# no passive-interface ethernet 1/1
2. B. router(config)# interface ethernet 1/1router(config-if)# no shutdown
3. C. router(config)# interface ethernet 1/1router(config-if)# ip ospf hello-interval
4. D. router(config)# interface ethernet 1/1router(config-if)# ip ospf priority 0

Correct Answer: A

An engineering team must implement Unified MPLS to scale an MPLS network. Devices in the core layer use different IGPs, so the team decided to split the network into different areas. The team plans to keep the MPLS services as they are and introduce greater scalability. Which additional action must the engineers take to implement the Unified MPLS?

1. A. Redistribute the IGP prefixes from one IGP into the other routers to ensure end-to-end LSPs.
2. B. Configure the ABR routers as route reflectors that redistribute IGP into BGP.
3. C. Redistribute the IGP prefixes into another IGP to ensure end-to-end LSPs.
4. D. Move the IGP prefixes into IS-IS as the loopback prefixes of the PE routers to distribute the prefixes to other routers to create end-to-end LSPs.

Correct Answer: C

Refer to the exhibit.

A network operator working for a telecommunication company with an employee ID: 4350:47:853 must implement an IGP solution based on these requirements:
• Subnet 10.50.10.0 traffic must exit through the R1 router to connect with the Syslog server.
• Subnet 10.50.20.0 traffic must exit through the R2 router to connect with the NTP server.
• In case of link failure between R2 and R4, traffic must be routed via R1 and R3.
Which two configurations must be implemented on R5 to meet these requirements? (Choose two.)

1. A. Apply a route policy to redistribute 10.50.0.0 prefixes in OSPF to ISIS and ISIS to OSPF.
2. B. Apply a route policy to redistribute 10.50.20.0 from ISIS-L2 to OSPF Area 0 at a higher cost.
3. C. Enable a route policy to advertise 10.50.20.0 in ISIS-L2 at a higher cost.
4. D. Apply a route policy to redistribute 10.50.10.0 from OSPF Area 0 to ISIS-L2 at a lower cost.
5. E. Enable a route policy to advertise 10.50.10.0 In OSPF Area 0 at a low cost.

Correct Answer: B
