An engineer has successfully set up a floating static route from the BRANCH router to the HQ network using HQ_R1 as the primary default gateway. When the g0/0 goes down on HQ_R1, the branch network cannot reach the HQ network 192.168.20.0/24.
Which set of configurations resolves the issue?

• A.HQ_R3(config)# ip sla responder HQ_R3(config)# ip sla responder icmp-echo 172.16.35.1
• B.BRANCH(config)# ip sla 1 BRANCH(config-ip-sla)# icmp-echo 192.168.100.2
• C.HQ R3(config)# Ip sla responder HQ R3(config)# Ip sla responder Icmp-echo 172.16.35.5
• D.BRANCH(config)# Ip sla 1 BRANCH(config-ip-sta)# Icmp-echo 192.168.100.1

Troubleshoot and ensure that branch B only ever uses the MPLS B network to reach HQ.
Which action achieves this requirement?

• A.Introduce an AS path filter on branch A routers so that only local prefixes are advertised into BGP
• B.increase the local preference for all HQ prefixes received at branch B from the MPLS B network to be higher than the local preferences used on the MPLS A network
• C.Introduce AS path prepending on the branch A MPLS B network connection so that any HQ advertisements from branch A toward the MPLS B network are prepended three times
• D.Modify the weight of all HQ prefixes received at branch B from the MPLS B network to be higher than the weights used on the MPLS A network

Show Answers

Answer:
Explanation:
If we modify the weight, increase local preference or use AS path prepending then we can only make MPLS B prefer over MPLS A. But when MPLS B is down then MPLS A will be used which does not meet the requirement of this question. Only with AS path filtering we can deny prefixes from certain AS and make sure branch B never uses MPLS A to reach HQ.

What is the minimum time gap required by the local system before putting a BFD control packet on the wire?

• A.Detect Mult
• B.Required Min Echo RX Interval
• C.Desired Min TX Interval
• D.Required Min RX Interval

Show Answers

Answer:
Explanation:
Desired Min TX Interval: This is the minimum interval, in microseconds, that the local system would like to use when transmitting BFD Control packets, less any jitterapplied. The value zero is reserved.
Required Min Echo RX Interval: This is the minimum interval, in microseconds, between received BFD Echo packets that this system is capable of supporting, less anyjitter applied by the sender. If this value is zero, the transmitting system does not support the receipt of BFD Echo packets.
