CCNP CIT Exam Cram 2 (Exam Cram 642-831)

Question 1

Which of the following port types allows more than one VLAN to traverse its links?

  • A. Any switched port

  • B. Any port that uses 10BaseT

  • C. An EtherChannel port

  • D. A switched port with ISL encapsulation configured

A1:

Answer: D . A switched port with ISL encapsulation configured would be a trunked port. Both ISL and IEEE 802.1Q allow more than one VLAN to traverse the link.

Question 2

Which command will enable you to display the following output?

Domain Name Domain Index VTP Version Local Mode Password ----------- ------ --------- ------- ---------- -------- DCS 1 2 server sean1 Vlan-count Max-vlan-storage Config Revision Notifications ---------- ---------------- --------------- ------------- 5 1023 355 enabled Last Updater V2 Mode Pruning PruneEligible on Vlans ------------ ------- ------- ---------------------- 68.38.127.5 enabled enabled 2-1000

  • A. show vtp

  • B. show vlan

  • C. show vtp all

  • D. show vtp domain

A2:

Answer: D . The show vtp domain command will enable you to display the output.

Question 3

Which of the following commands can be used on a router's subinterface to assign an encapsulation type?

  • A. set encapsulation isl 1

  • B. encapsulation isl 1

  • C. interface encasulation isl 1

  • D. isl encapsulation 1

A3:

Answer: B . The ISL encapsulation type on a router's interface can be assigned using the encapsulation isl 1 command.

Question 4

Which of the following trunking types would be used on a switch port if the port were connecting to a non-Cisco router or switch?

  • A. IEEE 802.5

  • B. IEEE 802.3

  • C. ISL

  • D. IEEE 802.1Q

A4:

Answer: D . IEEE 802.1Q is an industry-standard protocol supported on Cisco switches and routers to connect a trunked link to a non-Cisco router or switch.

Question 5

Although the management VLAN can be changed, what VLAN is the management VLAN by default?

  • A. VLAN 1

  • B. The VLAN assigned to an ISL trunked port

  • C. VLAN 1005

  • D. VLAN 64

A5:

Answer: A . All ports begin in VLAN 1 by default, which is also the VLAN management VLAN by default.

Question 6

Which of the following are VLAN encapsulation types supported on Cisco switches? [Choose the two best answers.]

  • A. Inter-Switch Link (ISL)

  • B. IEEE 802.5

  • C. STP

  • D. IEEE 802.1Q

A6:

Answer: A, D . A Cisco switch and router support both the IEEE 802.1Q protocol, which allows trunking to a non-Cisco device, and the Inter-Switch Link, which is a Cisco proprietary protocol for trunking.

Question 7

Which of the following devices enables you to route between VLANs?

  • A. An external route processor

  • B. A Route Switch Module (RSM)

  • C. A Route Switch Feature Card (RSFC)

  • D. All of the above

A7:

Answer: D . An internal or external route processor must be used to route between VLANs at Layer 3. An external route processor is a router. The RSM and RSFC are both internal route processors. All of which can route Layer 3 VLANs.

Question 8

Which of the following are benefits of implementing switches and virtual LANs?

  • A. Efficient bandwidth utilization

  • B. Load balancing among multiple paths

  • C. Isolation between problem components

  • D. All of the above

A8:

Answer: D . Efficient bandwidth utilization, load balancing among multiple paths, and isolation between problem components are all benefits of implementing switches and VLANs.

Question 9

Which of the following best describes a trunk link?

  • A. A link that enables access to the Internet

  • B. A link that enables FTP and HTTP to flow together

  • C. A link that can carry traffic for multiple VLANs

  • D. A link that is used only in token ring environments

A9:

Answer: C . A link that can carry traffic for multiple VLANs best describes a trunk link.
