It's Tuesday, August 12, and here are the answers to yesterday's Cisco practice exam questions!

CCNA Certification And CCENT Certification:

In the following configuration, name the default setting for the violation option, and define all available options for that command.

SW2(config)#int fast 0/1
SW2(config-if)#switchport mode access
SW2(config-if)#switchport access VLAN 10
SW2(config-if)#switchport port-security ?
aging Port-security aging commands
mac-address Secure mac address
maximum Max secure addresses
violation Security violation mode


Answer: The default mode is shutdown, and this mode shuts the port down, transmits a message to the log indicating the action taken, and drops the violating frames. The interface status will be err-disabled, (short for error-disabled) meaning it must be manually reopened.


Restrict drops the violating frames and transmits a message to the log indicating an issue, but does not shut the port down.


Protect simply drops the violating frames.



CCNA Security Certification / CCNP ISCW Exam:

When you're configuring SDM, you have two options for the location of SDF files. What are they?



Answer: You can specify a URL or Flash, as demonstrated by this screen shot from my CCNA Security Study Package. (Click the image for a larger version.)







CCNP Certification / BSCI Exam:

R1 is to be a BGP route reflector; R2 and R3 are to be the clients. Which routers require configuration to make this happen?

A. All involved routers.

B. Only R1.

C. Only R2 and R3.

D. None of them.



Answer: B. The involved command is route-reflector-client, but that command does not go on the clients - that command is configured on the route reflector itself, followed by the IP address(es) of the client(s).



In this example, R1 is configured to reflect routes to two other BGP speakers. Note that the adjacencies go down as a result of the configuration, but go back up quickly.



R1(config)#router bgp 1235
R1(config-router)#neighbor 172.12.123.2 route-reflector-client


00:34:00: %BGP-5-ADJCHANGE: neighbor 172.12.123.2 Down RR client config change


R1(config-router)#neighbor 172.12.123.3 route-reflector-client

00:34:12: %BGP-5-ADJCHANGE: neighbor 172.12.123.3 Down RR client config change

00:34:27: %BGP-5-ADJCHANGE: neighbor 172.12.123.2 Up

00:34:38: %BGP-5-ADJCHANGE: neighbor 172.12.123.3 Up

CCNP Certification / BCMSN Exam:

Identify the true statements regarding multilayer switches.

A. A VLAN exists by default.

B. An SVI exists by default.

C. Creating a VLAN automatically creates an SVI.

D. Creating an SVI automatically creates a VLAN.


Answer: A. VLAN 1 will be present by default, as with an L2 switch. No SVI is pre-created, and both C and D are false.


CCNP / ONT Exam: (My ONT Study Package will be out later this week!)

Identify the true statements regarding dial peers.

A. The destination-pattern refers to the remote router.

B. The destination-pattern refers to the local router.

C. POTS peers use the port command.

D. POTS peers use the session target command.

E. VOIP peers use the port command.

F. VOIP peers use the session target command.


Answers: A, C, F. Like a dialer map statement, the destination-pattern command always specifies a number to use to reach the remote router. POTS peers use the port command, VOIP peers use session-target. Both can use the destination-pattern command.

Later today and later this week, I'll have several new practice exams and tutorials on the main site, including new CCNA Security features! Click that link to access several free CCNA Security tutorials and exams, and I'll see you later today!


To your success,
