Refer to the exhibit. Router R1 peers with two ISPs using static routes to get to the internet. The requirement is that R1 must prefer ISP-A under normal circumstances and failover to ISP-B if the connectivity to ISP-A is lost. The engineer observes that R1 is load balancing traffic across the two ISPs Which action resolves the issue by sending traffic to ISP-A only with failover to ISP-B?

A.

Configure OSPF between R1. ISP-A. and ISP-B for dynamic failover if any ISP link to R1 fails

B.

Configure two static routes on R1. one pointing to ISP-A and another pointing to ISP- B with 222 admin distance

C.

Change the bandwidth of the interface on R1 so that interface to ISP-A has a higher value than the interface to ISP-B

D.

Configure two static routes on R1. one pointing to ISP-B with more specific routes and another pointing to ISP-A with summary routes

Refer to the exhibit.

Which control plane process allows the MPLS forwarding state to recover when a secondary RP takes over from a failed primary RP?

A.

MP-BGP uses control plane services for label prefix bindings in the MPLS forwarding table

B.

C.

FEC uses a control plane service to distribute information between primary and secondary processors

D.

LDP uses SSO to recover from disruption in control plane service

The network administrator configured R1 to authenticate Telnet connections based on Cisco ISE using TACACS+. ISE has been configured with an IP address of 192.168.1.5 and with a network device pointing toward R1(192.168.1.1) with a shared secret password of Cisco123.

Refer to the exhibit. An engineer configured two ASBRs, 10.4.17.6 and 10.4.15.5, in an OSPF network to redistribute identical routes from BGR However, only prefixes from 10.4.17.6 are installed into the routing table on R1. Which action must the engineer take to achieve load sharing for the BGP-originated prefixes?

A.

The ASBRs are advertising the redistributed prefixes with the iBGP metric and must be modified to Type 1 on ASBR 10.4.17.6.

B.

The ASBRs are advertising the redistributed prefixes with a different admin distance and must be changed to 110 on ASBR 10.4.15.5.

C.

The admin distance of the prefixes must be adjusted to 20 on ASBR 10.4.15.5 to advertise prefixes to R1 identically from both ASBRs.

D.

The ASBRs are advertising the redistributed prefixes as Type 1 and must be modified to Type 2
