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?

A planned EBGP network will use OSPF to reach the EBGP peer addresses. Which of these
conditions should be avoided in the design that could otherwise cause the peers to flap
continuously?

Yourdesign plan includes mutual redistribution of two OSPF networks at multiple locations,
with connectivity to all locations in both networks. How is this accomplished without creating
routing loops?

You are a network designer and are responsible for ensuring that the network you design is
secure. How do you plan to prevent infected devices on your network from sourcing random
DDoS attacks using forged source addresses?

Refer to the exhibit.You are developing a migration plan to enable IPv6 in your IPv4 network. Starting at R3 and
assuming default IS-IS operations, what is likely to happen when you enable IPv6 routing on the
link from R3 to R2?

Refer to the exhibit.In this BGP design, what is the next hop for 10.1.1.0/24 on R8 and R7?

Refer to the exhibit.This diagram depicts the design of a small network that will run EIGRP on R1 and R2, and EIGRP
Stub on R3. In which two ways will this network be impacted if there is link instability between
R1 and R2? (Choose two.)

Youare designing a network to support data, voice and video. Which two main factors will you
address to improve network convergence? (Choose two.)
