access-list 110 deny tcp 10.1.1.128 0.0.0.63 any eq smtp
access-list 110 deny tcp any eq 23
int ethernet 0
ip access-group 110 out
What will the result of this access list be?
Options
- A. Email and Telnet will be allowed out E0.
- B. Email and Telnet will be allowed in E0.
- C. Everything but email and Telnet will be allowed out E0.
- D. No IP traffic will be allowed out E0.
- Correct Answer
- No IP traffic will be allowed out E0.
Explanation
If you add an access list to an interface and you do not have at least one
permit statement, then you will effectively shut down the interface because of the implicit
deny any at the end of every list.

- 4. You have the following routing table. Which of the following networks will not be placed in the neighbor routing table?
R 192.168.30.0/24 [120/1] via 192.168.40.1, 00:00:12, Serial0
C 192.168.40.0/24 is directly connected, Serial0
172.16.0.0/24 is subnetted, 1 subnets
C 172.16.30.0 is directly connected, Loopback0
R 192.168.20.0/24 [120/1] via 192.168.40.1, 00:00:12, Serial0
R 10.0.0.0/8 [120/15] via 192.168.40.1, 00:00:07, Serial0
C 192.168.50.0/24 is directly connected, Ethernet0
Options
- A. 172.16.30.0
- B. 192.168.30.0
- C. 10.0.0.0
- D. All of them will be placed in the neighbor routing table.
Discuss
Correct Answer: 10.0.0.0
Explanation:
The network 10.0.0.0 cannot be placed in the next router's routing table because it already is at 15 hops. One more hop would make the route 16 hops, and that is not valid in RIP networking.
- 5. You have created a named access list called Blocksales. Which of the following is a valid command for applying this to packets trying to enter interface s0 of your router?
Options
- A. (config)# ip access-group 110 in
- B. (config-if)# ip access-group 110 in
- C. (config-if)# ip access-group Blocksales in
- D. (config-if)# blocksales ip access-list in
Discuss
Correct Answer: (config-if)# ip access-group Blocksales in
Explanation:
Using a named access list just replaces the number used when applying the list to the router's interface.
ip access-group Blocksales in is correct.
- 6. What multicast addresses does RIPng use?
Options
- A. FF02::A
- B. FF02::9
- C. FF02::5
- D. FF02::6
