Which command enables inline power on port 3 of module 2 of a Cisco Catalyst 6000 Series switch that is running Cisco Catalyst software?

  1. power inline in global configuration mode
  2. power inline auto in interface configuration mode
  3. set port inline power default
  4. set port inline power 3/2 802.3
  5. set port inline power 2/3 auto

Cisco Catalyst switches can provide which three functions in an IP telephony deployment? (Choose three.)

  1. Convert SCCP signaling packets from the IP Phone to MGCP.
  2. Power IP Phones through the same Ethernet cable that carries data.
  3. Enable the classification and prioritization of voice packets at Layer 2.
  4. Instruct the IP Phone to change the CoS of an incoming data frame.
  5. Determine available bandwidth before placing a call over the WAN.

What are three requirements for configuring dual VLANs on a single port that is attached to an IP Phone? (Choose three.)

  1. Configure the interface for access and voice VLANs.
  2. Tag the voice packets with a voice VLAN identifier.
  3. Extend the CoS boundary to the IP Phone.
  4. Ensure that the IP Phone has an internal switch.
  5. Ensure that the IP Phone is inline power-capable.

What three methods can you use to power all PoE-capable Cisco IP Phones?

  1. wall power
  2. solar power
  3. Cisco prestandard PoE
  4. IEEE 802.3af PoE
  5. Cisco Inline Power Patch Panel

Which of the following represent the industry standard PoE mechanism?

  1. 802.3
  2. 802.11
  3. 802.11b
  4. 802.3af

Which of the following commands will activate PoE on a Catalyst 3750 switch?

  1. set port inlinepower mod/port auto
  2. set port inlinepower mod/port on
  3. power inline auto
  4. power inline on

To support dual VLANs from a Catalyst 6500 running CatOS and a Cisco IP Phone, what should be configured? (Choose two.)

  1. an ISL trunk
  2. an 802.1Q trunk
  3. an auxiliary VLAN configuration
  4. a voice VLAN configuration

You are attempting to set up a dual VLAN configuration between a Cisco IP Phone and a CatOS-based 6500 switch. You enter the command set port auxiliaryvlan 3/1 50 to place the IP Phone on the voice VLAN 50. What more must be done?

  1. Configure an 802.1Q trunk.
  2. Configure an ISL trunk.
  3. Enable PoE.
  4. Nothing more must be done.

By default, a Cisco IP Phone tags all voice packets with what CoS value?

  1. 1
  2. 3
  3. 5
  4. 7

How does the Cisco IP Phone mark traffic from an attached PC?

  1. The Cisco IP Phone trusts the CoS marking coming from the attached PC.
  2. The Cisco IP Phone does not trust the CoS marking and sets it to 0.
  3. The Cisco IP Phone does not trust the CoS marking and sets it to 3.
  4. The Cisco IP Phone does not support CoS markings for data traffic.
