QUESTION 76
Refer to the exhibit. Clients that are connected to Fa0/0 of RTA are only allowed to connect to the Internet and networks, but not the networks on Fa1/0, Fa2/0, Fa3/0 and Fa4/0. To achieve this, you have configured an ACL on RTA and applied it on the incoming direction of interface Fa0/0.
After you apply this ACL, you learn that some of these networks are still accessible for clients that are connected to the 10.10.10.0/24 network. What is the correct ACL configuration to solve this issue?

A.    access-list 101 deny ip any 10.1.0.0 0.0.1.255 access-list 101 permit ip any any
B.    access-list 101 permit ip any 10.1.0.0 0.0.1.255 access-list 101 deny ip any any
C.    access-list 101 deny ip any 10.1.0.0 0.0.252.255 access-list 101 permit ip any any
D.    access-list 101 deny ip any 10.1.0.0 0.0.3.255 access-list 101 permit ip any any

Answer: D

QUESTION 77
You are the network administrator of a medium-sized company, and users are complaining that they cannot send emails to some organizations. During your troubleshooting, you notice that your DNS MX record is blacklisted by several public blacklist filters. After clearing these listings for your IP address, and assuming that your email server has the right virus protection in place, what are two possible solutions to prevent this from happening in the future? (Choose two.)

A.    Change your Internet provider.
B.    Change your public IP address.
C.    Allow the email server to send traffic only to TCP port 25.
D.    Put your email server in a DMZ.
E.    Use a separate public IP address for your email server only.

Answer: CE

QUESTION 78
Refer to the exhibit. What can be done to remove the summary routes to Null0 on R3?

A.    Configure the EIGRP routing subcommand no auto-summary on 209.165.202.155.
B.    Configure the EIGRP routing subcommand no auto-summary on 209.165.202.24.
C.    Configure the EIGRP routing subcommand no auto-summary on both 209.165.202.155 and 209.165.202.242.
D.    Configure the EIGRP routing subcommand no auto-summary on R3.

Answer: D

QUESTION 79
Refer to the exhibit. R4 is configured as a receive-only EIGRP stub, and is adjacent with 209.165.202.139 (R3).
However, R4 is not learning about network 209.165.201.0/27 from R3. What could be the cause of this issue?

A.    R4 should learn this route from 209.165.200.242, and not from R3.
B.    R3 is configured as a receive-only EIGRP stub.
C.    R3 and R4 may be using different EIGRP process numbers.
D.    R3 and R4 are asymmetrically adjacent neighbors.

Answer: B

QUESTION 80
Refer to the exhibit. R4 is a remote office router that is running EIGRP; the decision has been made to change EIGRP to use static EIGRP adjacencies. However, once the configuration change was applied, the adjacency between R4 and 209.165.202.139 (HQ) seems to disappear. What could be the cause of this issue?

A.    Static EIGRP neighbor configuration is symmetric; it causes the interface to stop processing inbound multicast packets and stop sending multicast packets.
B.    Static EIGRP neighbors are not displayed with the show ip eigrp neighbors command.
C.    A distance (internal 90 or external 170) must also be configured for the static neighbor.
D.    The neighbor 209.165.202.139 should be changed to run under EIGRP autonomous system 0.

Answer: A
