Question 6 Selectable Answer

Refer to the exhibit.

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

Question 7 Selectable Answer

Refer to the exhibit.

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

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.

Question 8 Selectable Answer

Refer to the exhibit

While troubleshooting an issue on the network, an engineer notices that a TCP Connect operation failed on port 3000 between R101 and R201.

A. ip sla responder udp-echo ipaddress 1.1.1.1 port 1967
B. ip sla responder tcp-connect ipaddress 1.1.1.1 port 3000
C. ip sla responder tcp-connect ipaddress 2.2.2.2 port 3001
D. ip sla responder

Question 9 Selectable Answer

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

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.

Question 13 Selectable Answer

Refer to the exhibit.

R1 has a route map configured, which results in a loss of partial IPv6 prefixes for the BGP neighbor, resulting in service degradation.
How can the full service be restored?

A. The neighbor requires a soft reconfiguration, and this will clear the policy without resetting the BGP TCP connection.
B. The prefix lit requires all prefixes that R1 is advertising to be added to it, and this will allow additional prefixes to be advertised.
C. The route map requires a deny 20 statement without set conditions, and this will allow additional prefixes to be advertised.
D. The route map requires a permit 20 statement without set conditions, and this will allow additional prefixes to be advertised.
