A Cisco IP phone receives untagged data traffic from an attached PC.

Which action is taken by the phone?

• It drops the traffic.

• It allows the traffic to pass through unchanged.

• It tags the traffic with the native VLAN.

• It tags the traffic with the default VLAN.

Which design element is a best practice when deploying an 802.11b wireless infrastructure?

• allocating nonoverlapping channels to access points that are in close physical proximity to one another

• disabling TCP so that access points can negotiate signal levels with their attached wireless devices

• configuring access points to provide clients with a maximum of 5 Mbps

• setting the maximum data rate to 54 Mbps on the Cisco Wireless LAN Controller

The network administrator wants VLAN 67 traffic to be untagged between Switch 1 and Switch 2, while all

other VLANs are to remain tagged.

Which command accomplishes this task?

• switchport access vlan 67

• switchport trunk allowed vlan 67

• switchport private-vlan association host 67

• switchport trunk native vlan 67

Which two command sequences must be configured on a switch to establish a Layer 3 EtherChannel

with an open-standard protocol? (Choose two.)

• interface GigabitEthernet0/0/1

  channel-group 10 mode auto

• interface GigabitEthernet0/0/1

  channel-group 10 mode on

• interface port-channel 10

  no switchport

  ip address 172.16.0.1 255.255.255.0

• interface GigabitEthernet0/0/1

  channel-group 10 mode active

• interface port-channel 10

  switchport

  switchport mode trunk

Which two commands were used to create port channel 10? (Choose two.)

• int range g0/0-1 channel-group

  10 mode active

• int range g0/0-1 channel-group

  10 mode desirable

• int range g0/0-1 channel-group

  10 mode passive

• int range g0/0-1 channel-group

  10 mode auto

• int range g0/0-1 channel-group

  10 mode on

An administrator is tasked with configuring a voice VLAN.

What is the expected outcome when a Cisco phone is connected to the GigabitEthernet 3/1/4 port on a

switch?

• The phone and a workstation that is connected to the phone do not have VLAN connectivity.

• The phone sends and receives data in VLAN 50, but a workstation connected to the phone sends and

  receives data in VLAN 1.

• The phone sends and receives data in VLAN 50, but a workstation connected to the phone has no

  VLAN connected.

• The phone and a workstation that is connected to the phone send and receive data in VLAN 50.

Which action is expected from SW1 when the untagged frame is received on the GigabitEthernet0/1

interface?

• The frame is processed in VLAN 1

• The frame is processed in VLAN 11

• The frame is processed in VLAN 5

• The frame is dropped

What two conclusions should be made about this configuration? (Choose two.)

• The root port is FastEthernet 2/1

• The designated port is FastEthernet 2/1

• The spanning-tree mode is PVST+

• This is a root bridge

• The spanning-tree mode is Rapid PVST+

A network engineer must create a diagram of a multivendor network.

Which command must be configured on the Cisco devices so that the topology of the network can be

mapped?

• Device(config)#lldp run

• Device(config)#cdp run

• Device(config-if)#cdp enable

• Device(config)#flow-sampler-map topology

How do AAA operations compare regarding user identification, user services, and access control?

• Authorization provides access control, and authentication tracks user services

• Authentication identifies users, and accounting tracks user services

• Accounting tracks user services, and authentication provides access control

• Authorization identifies users, and authentication provides access control
