Refer to the exhibit.

Youare designing a loop-free hierarchical VPLS service. Which two design considerations should
be implemented for the pseudowires between the N-PE and U-PE routers? (Choose two.)

Youare designing a Group Encrypted Transportvirtual private network solution for an existing
branch network. The existing network has the following characteristics:
 50 remote sites (with an additional 30 remote sites expected over
the next 3 years)
 Connectivity between all sites is via Multiprotocol Label Switching
Layer 3 virtual private network service from a single provider
 Open Shortest Path First is the routing protocol used between
provider edge and customer edge routers
 The customer edge routers will become group members
performing the encryption between sites
Which additional routing protocol would you use for the overlay routing between the group
members?

Youare tasked with implementing a 1000-phone remote access solution, where phones will
traverse a WAN edge router.Assuming all of the following features are supported in a
hardware-assisted manner, which of the following will have the most detrimental impact on the
delay of the packet?

Yourorganization is working on a design solution for a new Internet-based remote access
virtual private network that has 1000 remote sites. A network administrator recommends
GETVPN as the model because the network of today uses DMVPN, which results in a lot of
background NHRP control traffic. What is a potential problem with using GETVPN for this design
solution?

Youare 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.)

When designing a network, which two security features should be added to the design to
protect hosts from potential IPv6 neighbor discovery denial of service attacks at the access
layer? (Choose two.)

During a corporate merger, a network designer is asked for a solution that will provide
connectivity between the two enterprise networks. The solution must have the ability to
support video sessions so that the CEO can message merger activities to the employees. The
designer decides to consider multicast as a transport with MSDP to provide redundancy. Which
transport feature does the network designer need to apply to the interconnecting firewall to
ensure that Source-Active messages between the MSDP peers can be sent in both enterprise
networks?

Yournetwork operations team is deploying Access Control Lists (ACLs) across your Internet
gateways. They wish to place an ACL inbound on the Internet gateway interface facing the core
network (the “trusted” interface). Which one of these addresses would the ACL need for traffic
sourced from the inside interface, to match the source address of the traffic?

A data center provider has designed a network using these requirements:
 Two data center sites are connected to the public Internet.
 Both data centers are connected to different Internet providers.
 Both data centers are also directly connected with a private
connection for the internal traffic, and public Internet traffic can also be
routed at this direct connection.
 The data center provider has only one /19 public IP address block.
Under normal conditions, Internet traffic should be routed directly to the data center where the
services are located. When one Internet connection fails, the complete traffic for both data
centers should be routed by using the remaining Internet connection. In which two ways can
this routing be achieved? (Choose two.)

When designing a large full mesh network running OSPF, how would you reduce LSA repetition?
