Refer to the exhibit. The DHCP client is unable to receive an IP address from the DHCP server RouterB is configured as follows:
Interface fastethernet 0/0 description Client DHCP ID 394482431 Ip address 172 31 11 255 255.255 0 !i p route 172.16.1.0 255 255 255.0 10.1.1.2 Which command is required on the fastethernet 0/0 interface of RouterB to resolve this issue?
RouterB(config-if)#lp helper-address 172.31.1.1
RouterBiconfig-ififclp helper-address 255.255 255 255
RouterB(config-if)#lp helper-address 172.16.1.1
RouterB(config-if)#lp helper-address 172.16.1.2
What are two purposes of using IPv4 and VPNv4 address-family configurations in a Layer 3 MPLS VPN? (Choose two.)
The VPNv4 address is used to advertise the MPLS VPN label.
RD is prepended to the IPv4 route to make it unique.
MP-BGP is used to allow overlapping IPv4 addresses between customers to advertise through the network.
The IPv4 address is needed to tag the MPLS label.
The VPNv4 address consists of a 64-bit route distinguisher that is prepended to the IPv4 prefix.
Refer to the exhibit. The Los Angeles and New York routers are receiving routes from Chicago but not from each other Which configuration fixes the issue?
Interface Tunnel1 no ip split-horizon eigrp 111
Interface Tunnel1
Ip next-hop-self elgrp 111
Interface Tunnel1 tunnel mode Ipsec Ipv4
Interface Tunnel1 tunnel protection ipsec profile IPSec-PROFILE
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?
HQ_R3(config)# ip sla responder
HQ_R3(config)# ip sla responder icmp-echo 172.16.35.1
BRANCH(config)# ip sla 1
BRANCH(config-ip-sla)# icmp-echo 192.168.100.2
HQ R3(config)# Ip sla responder
HQ R3(config)# Ip sla responder Icmp-echo 172.16.35.5
BRANCH(config)# Ip sla 1
BRANCH(config-ip-sta)# Icmp-echo 192.168.100.1
What are two functions of MPLS Layer 3 VPNs? (Choose two.)
LDP and BGP can be used for Pseudowire signaling.
It is used for transparent point-to-multipoint connectivity between Ethernet links/sites.
BGP is used for signaling customer VPNv4 routes between PE nodes.
A packet with node segment ID is forwarded along with shortest path to destination.
Customer traffic is encapsulated in a VPN label when it is forwarded in MPLS network.
When configuring Control Plane Policing on a router to protect it from malicious traffic, an engineer observes that the configured routing protocols start flapping on that device. Which action in the Control Plane Policy prevents this problem in a production environment while achieving the security objective?
Set the conform-action and exceed-action to transmit initially to test the ACLs and transmit rates and apply the Control Plane Policy in the output direction
Set the conform-action and exceed-action to transmit initially to test the ACLs and transmit rates and apply the Control Plane Policy in the input direction
Set the conform-action to transmit and exceed-action to drop to test the ACLs and transmit rates and apply the Control Plane Policy m the input direction
Set the conform-action to transmit and exceed-action to drop to test the ACLs and transmit rates and apply the Control Plane Policy m the output direction
Refer to the exhibit. The administrator configured route advertisement to a remote low resources router to use only the default route to reach any network but failed. Which action resolves this issue?
Change the direction of the distribute-list command from out to in.
Remove the line with the sequence number 5 from the prefix list.
Remove the prefix keyword from the distribute-list command.
Remove the line with the sequence number 10 from the prefix list.
Refer to the exhibit. The remote server is failing to receive the NetFlow data Which action resolves the issue?
Modify the flow transport command transport udp 2055 to move under flow monitor profile.
Modify the interlace command to Ip flow monitor FLOW-MONITOR-1 Input.

route map to set the metrics of learned routes to 110
OSPF priority greater than 1
Refer to the exhibit. The network administrator has configured the Customer Edge router (AS 64511) to send only summarized routes toward ISP-1 (AS 100) and ISP-2 (AS 200). router bgp 64511 network 172.16.20.0 mask 255.255.255.0 network 172.16.21.0 mask 255.255.255.0 network 172.16.22.0 mask 255.255.255.0 network 172.16.23.0 mask 255.255.255.0 aggregate-address 172.16.20.0 255.255.252.0 After this configuration. ISP-1 and ISP-2 continue to receive the specific routes and the summary route. Which configuration resolves the issue?
