You are the lead network designer for an enterprise company called ABC, and you are leading design discussions regarding IPv6 implementation into their existing network. A question is raised regarding older Layer 2 switches that exist in the network, and if any changes are required to these Layer 2 switches for successful IPv6 implementation. Which two responses should you give? (Choose two.)

What is the advantage of using a router instead of a switch when implementing Hierarchical VPLS (H-VPLS) CE devices?

Refer to the exhibit.

A service provider using IS-IS has designed this network with all core links at the Layer 2 control plane.
How will they adjust the design to reduce the flooding of update packets?

You are a network designer and have been asked to consult with your server operations team to
further enhance the security of the network. The operations team provides you with these details
about the network:
-A pool of servers is accessed by numerous data centers and remote sites.
-The servers are accessed via a cluster of firewalls.
-The firewalls are configured properly and are not dropping traffic.
-The firewalls occasionally cause asymmetric routing of traffic within the server data center.
Which technology would you recommend to enhance security by limiting traffic that could originate
from a hacker compromising a workstation and redirecting flows at the servers?

Refer to the exhibit.

What limitations exist in this design, given that the access layer devices are expected to steadily increase by two devices per week for the next year?
