Question 1

ASN 65001 is peering with ASN 65002 to exchange IPv6 BGP routes. All routes that originate in ASN 65001 have a standard community value of 65001:100, and ASN 65002 is allowed to advertise only 2001 :db8:aaaa::/48. An engineer needs to update the ASN 65001 route-filtering configuration to meet these conditions:
- Looped routes into ASN 65001 and routes that have traversed 10 or
more ASNs must be denied.
- Routes accepted into ASN 65001 must be assigned a community value of
65001:200.
Which configuration must the engineer apply to the ASN 65001 border router?

A.

B.

C.

D.

Correct Answer: B

Question 2

Which characteristic describes prefix segment identifier?

A. it contains the interface address of the device per each link.

B. It contains a router to a neighbor.

C. it is locally unique.

D. It Is globally unique.

Correct Answer: D

Question 3

Refer to the exhibit. ASN 64501 currently reaches the networks under the 10.0.0.0/8 prefix via the North_B router, which is a slow backup link.
The administrator of ASN 64502 wants traffic from ASN 64501 to 10.0.0.0/8 to travel via the primary link North_A.
Which change to the network configuration accomplishes this task?

A. Set a Lower Weight value for incoming traffic on North_A

B. Set a lower MED between North_B and South_B

C. Set a higher local preference between North_A and South_A

D. Advertise the 10.0.0.0/8 prefix through North_B and specific subnets through North_A

Correct Answer: D

Question 4

What is the feature of the Unified MPLS architecture?

A. It uses a flat Level 2 or backbone area network throughout the entire IGP domain

B. It exchanges label information using BGP

C. ABR routers are part of the iBGP mesh design and participate in exchange of all VPN prefixes

D. The MPLS label stack reqquires 8bytes of overhead between the ingress and egress PEs

Correct Answer: B

Question 5

Refer to me exhibit. A network operator recently configured BGP FlowSpec for me internal IT network.
What will be inferred from the configuration deployed on me network?

A. The policy is configured locally on CSR1 and currently has no active traffic

B. The policy is configured locally on CSRl and drops all traffic for TCP ports 80 and 443

C. The policy is warned via BC FlowSpec aid has active traffic

D. The policy is learned via BGP FlowSpec and drops all traffic for TCP ports 80 and 443

Correct Answer: B

Question 6

A remote operation center is deploying a set of l-BGP and E-BGP connections for multiple IOS- XR platforms using the same template. The l-BGP sessions exchange prefixes with no apparent issues, but the E-BGP sessions do not exchange routes. What causes this issue?

A. The E-BGP neighbors are not allowed to exchange information due to the customer platforms default policy.

B. The next-hop-self command is not implemented on both E-BGP neighbors.

C. A PASS ALL policy has not been implemented for the l-BGP neighbors.

D. The l-BGP neighbors are mistyped and HELLO packets cannot be exchanged successfully between routers.

Correct Answer: A

Question 7

R1 serves as a route reflector on a BGP-enabled network and has dual RPs installed. To ensure that all routes have been processed when an RP fails over, R1 must send the router request to all peers configured with NSR to refresh the route database. Which action completes the implementation?

A. Implement bgp fast-external-failover under the BGP IPv4 address-family configuration.

B. Enable bgp sso route-refresh-enable in the global BGP configuration.

C. Enable bgp ietf rp route-update in the global router configuration.

D. Implement bgp consistency-checker auto-repair under the Cisco Express Forwarding configuration.

Question 8

Which descriptions of Netflow is correct? (Choose three.)

A. Netflow answers questions regarding IP traffiC. who, what, where, when, and how

B. Netflow returns the subinterface information in the flow records.

C. Netflow accounts for both transit traffic and traffic destined for the router.

D. By default,Netflow records bidirectional IP traffic flow.

Correct Answer: A,B,C

Question 9

An engineer is configuring IEEE 802. 1ad on the access port on a new Cisco router. The access port handles traffic from multiple customer VLANs, and it is expected to mark allcustomer traffic to the same VLAN without dropping any traffic. Which configuration must the engineer apply?

A. interface gigabitethernet0/0/1 ethernet dot1ad uni c-port

B. interface gigabitethernet0/0/1 ethernet dot1ad uni s-port

C. interface gigabitethernet0/0/1 ethernet dot1ad uni nni

D. interface gigabitethernet0/0/1 encapsulation dot1q 10

Correct Answer: B
