Key VTP and STP Networking Concepts

1. What does a VTP client mode switch do when it receives a summary publication with a higher revision number?

• A. Shipping is suspended until it receives the update subset of publications.
• B. Issues a request for publication for the new VLAN information.
• C. Updates the revision number and sends it to the other switches.
• D. Deletes VLANs not included in the summary publication.
• E. Sends summary publications to warn the other switches about state changes.
• F. None of the above

2. What causes a VTP configured switch to issue a summary publication?

• A. Five minutes have elapsed on the update timer.
• B. A switch port is disabled.
• C. The switch mode is changed to transparent.
• D. A new host is added to the switch in the management domain.
• E. 100 seconds have elapsed on the update timer.
• F. None of the above

3. Which three VTP parameters must be identical for switches to participate in a VTP domain? (Choose three.)

• A. Revision number
• B. Domain name
• C. Debugging
• D. So
• E. Domain password
• F. Version number

4. How are VTP messages sent between switches in a domain?

• A. Layer 2 Broadcast
• B. Layer 2 Multicast
• C. Layer 2 Unicast
• D. Layer 3 Broadcast
• E. Layer 3 Multicast
• F. Layer 3 Unicast

5. Which two elements exist in a converged network with a single spanning tree? (Choose two.)

• A. A root bridge per network
• B. All non-designated ports forward traffic.
• C. A root port for each non-root bridge
• D. Multiple designated ports per segment
• E. A designated port per network
• F. None of the above

6. Which two criteria does a switch use to select the root bridge? (Choose two.)

• A. Bridge priority
• B. Switching speed
• C. Number of ports
• D. Base MAC address
• E. Switch location
• F. Memory size

7. How do switches use the information contained in BPDUs? (Choose two.)

• A. To negotiate a trunk link between switches
• B. To set the duplex mode of a redundant link
• C. To identify the shortest path to the root bridge
• D. To prevent loops by sharing bridging tables between connected switches
• E. To determine which ports forward frames as part of the spanning tree
• F. None of the above.

8. Which two statements describe the Bridge ID (BID) used in a spanning tree topology? (Choose two.)

• A. Are sent by the root bridge only after inferior BPDUs are sent.
• B. They consist of a bridge priority and MAC address.
• C. Only the root bridge sends a BID.
• D. They are used by switches in a spanning tree topology to select the root bridge.
• E. The switch with the fastest processor has the lowest BID.
• F. None of the above.

9. In which STP state does a port record MAC addresses but not send user data?

• A. Blocking
• B. Learning
• C. Disabled
• D. Listening
• E. Forwarding
• F. Letter.
