Refer to the exhibit. The operations team is implementing a route-map policy. Traffic from source
192.168.30.1 must reach the customer network 192.168.1.1 via the secondary link R4-R6-R5. All other traffic from the data center to the customer network must prefer the primary link R4-R3-R2.
Which action must be taken to meet the requirement for prefix 192.168.1.1/32?

A. Apply route-map High-LP on R6 with R4 BGP peering.

B. Apply route-map PrefixBlock out on R3 with R4 BGP peering.

C. Apply route-map Low-LP in on R4 with R3 BGP peering

D. Apply route-map PrefixBlock in on R6 with R5 BGP peering.

Correct Answer: C

Question 6

The NOC engineer in a service provider network must configure an SNMP community on switch SW with these security attributes:
- Event messages must be authenticated with the MD5 algorithm and
encrypted.
- The remote user name for the SNMP server at 172.16.10.1 is
AuthNocUser.
Which configuration must the engineer apply to the switch?

A.

B.

C.

D.

Correct Answer: C

Question 7

What is a primary benefit of IPoATM or MPLS over ATM backbone service provider networks?

A. isochronous system

B. dedicated circuits

C. fixed-length cells

D. variable-length packets

Correct Answer: B

Question 8

What are two results of implementing this feature instead of traditional NetFlow? (Choose two.)

A. The number of packets to be analyzed are reduced.

B. The data export flow is more secure

C. Only the flows of top 100 talkers are exported.

D. The accuracy of the data to be analyzed is improved.

E. CPU and memory utilization are reduced.

Correct Answer: A,E

Question 9

Refer to the exhibit. A service provider is running MPLS in the core to support Layer 3 VPN.
OSPF is configured to support dynamic routing, and BGP is enabled throughout the network. A network engineer is adding a new P router to the infrastructure and is connecting it to P1 and P3.

A. Configure OSPF and BGP to support MPLS.

B. Establish an LDP neighbor relationship with P1 and P3.

C. Enable LDP sync under the OSPF routing process.

D. Enable LDP and establish an OSPF adjacency in a new area.
