An administrator is investigating a failure on a trunk link between a Cisco switch and a switch from another vendor. After a few show commands, the administrator notices that the switches are not negotiating a trunk. What is a probable cause for this issue?

a. Both switches are in trunk mode.

b. Both switches are in nonegotiate mode.

c. Switches from other vendors do not support DTP.

d. DTP frames are flooding the entire network.

c. Switches from other vendors do not support DTP.

What is the purpose of the vlan.dat file on a switch?

a. It holds the running configuration.

b. It holds the saved configuration.

c. It holds the VLAN database.

d. It holds the operating system.

c. It holds the VLAN database.

What is the purpose of setting the native VLAN separate from data VLANs?

a. The native VLAN is for carrying VLAN management traffic only.

b. The security of management frames that are carried in the native VLAN can be enhanced.

c. A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs.

d. The native VLAN is for routers and switches to exchange their management information, so it should be different from data VLANs.

c. A separate VLAN should be used to carry uncommon untagged frames to avoid bandwidth contention on data VLANs.

When a Cisco switch receives untagged frames on a 802.1Q trunk port, which VLAN ID is the traffic switched to by default?

a. Unused VLAN ID

b. Native VLAN ID

c. Data VLAN ID

d. Management VLAN ID

b. Native VLAN ID

b. Between a switch and a client PC

c. Between a switch and a server that has an 802.1Q NIC

d. Between a switch and a network printer

e. Between two switches that share a common VLAN

a. Between two switches that utilize multiple VLANs

c. Between a switch and a server that has an 802.1Q NIC

What are three primary benefits of using VLANs? (Choose three.)

a. Security

b. A reduction in the number of trunk links

c. Cost reduction

d. End user satisfaction

e. Improved IT Staff efficiency
