QUESTION 22

What are the three modes of Unicast Reverse Path Forwarding?

A. strict mode, loose mode, and VRF mode

B. strict mode, loose mode, and broadcast mode

C. strict mode, broadcast mode, and VRF mode

D. broadcast mode, loose mode, and VRF mode

Correct Answer: A

Network administrators can use Unicast Reverse Path Forwarding (Unicast RPF) to help limit the malicious traffic on an
enterprise network. This security feature works by enabling a router to verify the reachability of the source address in
packets being forwarded. This capability can limit the appearance of spoofed addresses on a network. If the source IP
address is not valid, the packet is discarded. Unicast RPF works in one of three different modes: strict mode, loose
mode, or VRF mode. Note that not all network devices support all three modes of operation. Unicast RPF in VRF mode
will not be covered in this document. When administrators use Unicast RPF in strict mode, the packet must be received
on the interface that the router would use to forward the return packet. Unicast RPF configured in strict mode may drop
legitimate traffic that is received on an interface that was not the router\\'s choice for sending return traffic. Dropping this
legitimate traffic could occur when asymmetric routing paths are present in the network. When administrators use
Unicast RPF in loose mode, the source address must appear in the routing table. Administrators can change this
behavior using the allow-default option, which allows the use of the default route in the source verification process.
Additionally, a packet that contains a source address for which the return route points to the Null 0 interface will be
dropped. An access list may also be specified that permits or denies certain source addresses in Unicast RPF loose
mode. Care must be taken to ensure that the appropriate Unicast RPF mode (loose or strict) is configured during the
deployment of this feature because it can drop legitimate traffic. Although asymmetric traffic flows may be of concern
when deploying this feature, Unicast RPF loose mode is a scalable option for networks that contain asymmetric routing
paths. Reference: http://www.cisco.com/web/about/security/intelligence/unicast-rpf.html

QUESTION 23

Refer to the exhibit.

Which one statement is true?

A. Traffic from the 172.16.0.0/16 network will be blocked by the ACL.

B. The 10.0.0.0/8 network will not be advertised by Router B because the network statement for the 10.0.0.0/8 network
is missing from Router B.

C. The 10.0.0.0/8 network will not be in the routing table on Router B.

D. Users on the 10.0.0.0/8 network can successfully ping users on the 192.168.5.0/24 network, but users on the
192.168.5.0/24 cannot successfully ping users on the 10.0.0.0/8 network

E. Router B will not advertise the 10.0.0.0/8 network because it is blocked by the ACL.

Correct Answer: E

You can filter what individual routes are sent (out) or received (in) to any interface within your EIGRP configuration.

One example is noted above. If you filter outbound, the next neighbor(s) will not know about anything except the
172.16.0.0/16 route and therefore won\\'t send it to anyone else downstream. If you filter inbound, YOU won\\'t know
about the

route and therefore won\\'t send it to anyone else downstream.
