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?
A. Only R3 and R2 have IPv4 and IPv6 reachability.
B. R2 receives an IPv6 default route from R3.
C. Loopback reachability between all routers for IPv4 is lost.
D. All routers except R2 are reachable through IPv4.

QUESTION 41
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?
A. ACL-based forwarding
B. ACL filtering by destination
C. Unicast RPF loose mode
D. Unicast RPF strict mode
Correct Answer: D
QUESTION 42
Your design 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?
A. Use route maps on the ASBRs to allow only internal routes to be redistributed.
B. Use route maps on the ASBRs to allow internal and external routes to be redistributed.
C. Use route maps on the ASBRs to set tags for redistributed routes.
D. Use route maps on the ASBRs to filter routes with tags so they are not redistributed.
Correct Answer: D
QUESTION 43
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?
A. An ACL blocks TCP port 179 in one direction.
B. IP addresses used to peer are also being sent via EBGP.
C. The OSPF area used for peering is nonbackbone (not area 0).
D. The routers are peered by using a default route sent by OSPF.
Correct Answer: B
QUESTION 44
When designing a large full mesh network running OSPF, how would you reduce LSA repetition?
A. Elect a DR and BDR.
B. Use access control lists to control outbound advertisements.
C. Choose one or two routers to re-flood LSA information.
D. Put each of the point-to-point links in your full mesh networking into a separate area.
Correct Answer: C
QUESTION 45
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.)
A. The data center provider must have an additional public IP address block for this routing.
B. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP weight and the / 20 block from the remote data center is sent out with a higher BGP weight at both sites.
C. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out without path prepending and the / 20 block from the remote data center is sent out with path prepending at both sites.
D. One /20 block is used for the first data center and the second /20 block is used for the second data center. Each /20 block is only sent out locally. The /19 block is sent out at both Internet connections for the backup case to reroute the traffic through the remaining Internet connection.
E. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP local preference and the /20 block from the remote data center is sent out with a higher BGP local preference at both sites.
F. BGP will always load-balance the traffic to both data center sites.
