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?

1. A. HQ_R3(config)# ip sla responderHQ_R3(config)# ip sla responder icmp-echo 172.16.35.1
2. B. BRANCH(config)# ip sla 1BRANCH(config-ip-sla)# icmp-echo 192.168.100.2
3. C. HQ R3(config)# Ip sla responderHQ R3(config)# Ip sla responder Icmp-echo 172.16.35.5
4. D. BRANCH(config)# Ip sla 1BRANCH(config-ip-sta)# Icmp-echo 192.168.100.1

How is VPN routing information distributed in an MPLS network?

1. A. The top level of the customer data packet directs it to the correct CE device
2. B. It is established using VPN IPsec peers.
3. C. It is controlled using of VPN target communities.
4. D. It is controlled through the use of RD.

Correct Answer: C
The distribution of virtual private network (VPN) routing information is controlled through the use of VPN route target communities, implemented by Border Gateway Protocol (BGP) extended communities.

Refer to the exhibit. An engineer configured SNMP traps to record spoofed packets drop of more than 48000 a minute on the ethernet0/0 interlace. During an IP spoofing attack, the engineer noticed that no notifications have been received by the SNMP server. Which configuration resolves the issue on R1?

1. A. ip verity unicast notification threshold 48000
2. B. ip verify unicast notification threshold 8000
3. C. ip verify unicast notification threshold 800
4. D. ip verify unicast notification threshold 80

Refer to the exhibit.

An engineer configures a static route on a router, but when the engineer checks the route to the destination, a different next hop is chosen. What is the reason for this?

1. A. Dynamic routing protocols always have priority over static routes.
2. B. The metric of the OSPF route is lower than the metric of the static route.
3. C. The configured AD for the static route is higher than the AD of OSPF.
4. D. The syntax of the static route is not valid, so the route is not considered.

Correct Answer: C
The AD of static route is manually configured to 130 which is higher than the AD of OSPF router which is 110.
