A newly installed router starts establishing an LDP session from another MPLS router to which it
is not directly connected. Which LDP message type responds by target router to the initiating
router using UDP protocol?

• A. advertisement message
• B. notification message
• C. session message
• D. extended discovery message

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. 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
• C. 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
• D. 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

Guidelines
This is a lab item in which tasks will be performed on virtual devices.
* Refer to the Tasks tab to view the tasks for this lab item.
* Refer to the Topology tab to access the device console(s) and perform the tasks.
* Console access is available for all required devices by clicking the device icon or using the
tab(s) above the console window.
* All necessary preconfigurations have been applied.
* Do not change the enable password or hostname for any device.
* Do not replace existing routing policies or configurations.
* Save your configurations to NVRAM before moving to the next item.
* Click Next at the bottom of the screen to submit this lab and move to the next question.
* When Next is clicked, the lab closes and cannot be reopened.
Topology

Tasks
A network is configured with CoPP to protect the CORE router route processor for stability and
DDoS protection. As a company policy, a class named class-default is preconfigured and must
not be modified or deleted. Troubleshoot CoPP to resolve the issues introduced during the
maintenance window to ensure that:
1. Dynamic routing policies are under CoPP-CRITICAL and are allowed only from the 10.10.x.x
range.
2. Telnet, SSH, and ping are under CoPP-IMPORTANT and are allowed strictly to/from 10.10.x.x
to the CORE router (Hint: you can verify using Loopback1).
3. All devices ping (UDP) any CORE router interface successfully to/from the 10.10.x.x range and
do not allow any other IP address.
4. All devices run a successful traceroute (UDP) to any interface on the CORE router to/from the
10.10.x.x range, are under CoPP-NORMAL, and do not allow any other IP address traceroute is
to be under CoPP-NORMAL (Hint: Traceroute port range 33434 33464).

Which access list entry checks for an ACK within a packet header?

• A. access-list 49 permit tcp any any eq 21 tcp-ack
• B. access-list 49 permit tcp any any eq 21 established
• C. access-list 49 permit ip any any eq 21 tcp-ack
• D. access-list 149 permit tcp any any eq 21 established
