Which service is a VNF role?

1. A. Compute
2. B. Network
3. C. Firewall
4. D. Storage

Correct Answer: B

Which Cisco software OS uses monolithic architecture?

1. A. NX-OS
2. B. IOS XE
3. C. IOS XR
4. D. IOS

Correct Answer: D
Cisco Internetwork Operating System (IOS) is the software used on most Cisco Systems routers and current Cisco network switches. IOS is a package of routing, switching, internetworking and telecommunications functions integrated into a multitasking operating system. IOS uses a monolithic architecture, meaning that all processes run in a single address space, making it a single-image system.

An engineer with an employee 10:4350:47:853 is implementing IS-IS as the new routing protocol in the network. All routers in the network operate as Level 2 routers in the same private autonomous system, and the three branches are connected via dark fibre. The engineer has already implemented IS-IS on router R1 with NET address 49.0133.532b.ca14.6915.21311.F40F.1B3a.ba10.00. Which IS-IS NET address configuration must be implemented on R3 to establish IS-IS connectivity?

1. A. 49.0133.532b.ca14.6915.21311.f40f.1b4a.bb87.00
2. B. 49.0135.332b.ca14.6975.28371.1721.1b3b.ca11.10
3. C. 48.0133.532b.ca14.6915.21311.f40f.1626.bb98.00
4. D. 49.0133.532b.ca14.6915.21311.1721.1b4a.0013.01

Correct Answer: A
IS-IS uses NET addresses to identify each router in the network, and the NET address of each router must be unique. In order for IS-IS to establish connectivity between R1 and R3, the NET address of R3 must be different from the NET address of R1, but it must also follow the same structure. In this case, the NET address of R1 is 49.0133.532b.ca14.6915.21311.F40F.1B3a.ba10.00, so the NET address of R3 must be 49.0133.532b.ca14.6915.21311.F40F.1B4a.bb87.00.

A network team has failed to implement IS-IS multitopology. What is the reason for it?

1. A. The router did not support VRFs.
2. B. The routing process did not support extended metrics.
3. C. The router did not have Cisco Discovery Protocol and Cisco Express Forwarding disabled.
4. D. The routing process supported Level 1 only.

Correct Answer: B

Refer to the exhibit.

A network engineer is implementing a standard customer route-policy on ASBR1 with these requirements:
• It must accept only customer-assigned prefixes
• It must preserve customer advertised BGP communities
• It must set the local-preference to 110 for all prefixes
• It must attach the ORIGINATION-PE and LOCAL-CITY communities to all accepted prefixes. Which route policy must the engineer implement on ASBR1 to satisfy the requirements?

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

Correct Answer: D
