CCNA: 10-Question Practice Exam

With the Cisco certpocalyse creeping up on us, there are a lot of people making a final mad dash to their CCNA. If you're among them, then you've probably watched every CBT Nuggets video, built more than your fair share of topologies, and likely exhausted every practice exam you can find. So, here's one more.

Answer these 10 questions to get a feel for the questions you may see on the CCNA ICND2 exam. Don't forget that unlimited Kaplan IT practice exams come with every CBT Nuggets subscription. Good luck!

1. What technology is in use of you see the following command in the running configuration of a Cisco switch?

1    monitor session 1 destination interface gigabitethernet 5/48

1. NetFlow

2. IP SLA

3. SPAN

4. SNMP

Correct Answer: c

Correct Answer: c

Explanation: The Switched Port Analyzer (SPAN) feature permits the copying of frames to an external destination (device) for analysis. This feature is critical since, by default, a switch restricts the sending of frames to specific destination ports.

2. What command enables you to see your EIGRP for IPv6 neighbors?

1. show eigrp neighbor ipv6

2. show eigrp ipv6 neighbor

3. show ipv6 eigrp neighbor

4. show ipv6 eigrp peering

Correct Answer

Correct Answer: c

Explanation: Notice that this is another example of a "search and replace" when it comes to IPv6 commands compared to their IPv4 counterparts. Instead of show ip eigrp neighbor, in this case we have show ipv6 eigrp neighbor.

3. Which version of SNMP provides rich security mechanisms?

1. snmp v1

2. snmp v2

3. snmp v2c

4. snmp v3

5. snmp v3c

Correct Answer

Correct Answer: d

Explanation: SNMP version 3 is the latest version in use and provides rich security mechanisms when compared to the previous version of SNMP v2c.

4. You issue the "show vlan brief" command on your new Cisco switch. You are confused as to why some of the ports are completely missing from the output. What is the most likely reason?

1. The ports are in an Kill disabled state

2. The ports have full input buffers

3. The ports are trunk ports

4. The ports are voice VLAN access ports

Correct Answer

Correct Answer: c

Explanation: Trunk ports will not display in the show vlan brief output. These ports are not participating in a single VLAN, instead they are carrying the traffic of all VLANs by default.

5. What is the routing protocol code for BGP in the routing table?

1. E

2. I

3. B

4. X

Correct Answer

Correct Answer: c

Explanation: Routes in the routing table for BGP (both internal and external) will have a routing protocol code of B. Sometimes questions in your exam are just not that hard!

6. What subprotocol is in charge of setting up and maintaining PPP links?

1. LCP

2. NCP

3. CHAP

4. PAP

Correct Answer

Correct Answer: a

Explanation: The Link Control Protocol (LCP) forms part of the Point-to-Point Protocol (PPP), within the family of Internet protocols. In setting up PPP communications, both the sending and receiving devices send out LCP packets to find the standards of the ensuing data transmission. The LCP protocol: checks the identity of the linked device and either accepts or rejects the device; determines the acceptable packet size for transmission; searches for Kills in configuration; can terminate the link if requirements exceed the parameters.

7. What authentication protocol is in wide use today such as with the IEEE 802.11 WPA and WPA2 standards?

1. CHAP

2. MD5

3. 3DES

4. EAP

Correct Answer

Correct Answer: d

Explanation: There are many forms of the Extensible Authentication Protocol (EAP) that are in use today. For example, IEEE 802.1X uses Extensible Authentication Protocol over IEEE 802, which is known as "EAP over LAN" or EAPoL.

8. Why might an access port on a Cisco switch be participating in more than one VLAN?

1. The port is configured with a Voice VLAN

2. The port is a trusted port for DHCP Snooping

3. The port is a trunk port

4. The port is a wireless port

Correct Answer

Correct Answer: a

Explanation: Trunk ports traditionally participate in multiple VLANs. But an access port may also do this. A classic case is where there is a Voice VLAN and a Data VLAN configured on the port.

9. Which of the following is a Cisco FHRP protocol?

1. PPPoE

2. GRE

3. HSRP

4. STP

Correct Answer

Correct Answer: c

Explanation: The Hot Standby Router Protocol (HSRP) is an example of a First Hop Reachability Protocol (FHRP) used in Cisco networks. In fact, HSRP is a Cisco invention.

10. What VLAN are permitted by a trunk link by default?

1. Only the Native VLAN

2. VLAN 0

3. All active VLANs in the switched infrastructure

4. VLANs 0 and 1

Correct Answer

Explanation: All active VLANs in the switched infrastructure are permitted on a trunk link by default. You can control this with the switchport trunk allowed vlan command in interface configuration mode.
