Answer

Spanning Tree Protocol (STP)

Question 12

You've created flashcards for common network commands. You find yourself consistently getting the 'show ip interface brief' command wrong. What study strategy should you employ based on active recall?

Accepted Answer

Review the card more frequently and try to recall the command without looking at the answer.

Answer

Which protocol and its associated implementation is the most efficient solution?

Accepted Answer

DHCP (Dynamic Host Configuration Protocol) server.

Answer

Static IP assignment manually configured on each device.

Answer

APIPA (Automatic Private IP Addressing) for all devices.

Answer

ARP (Address Resolution Protocol) to manage IP assignments.

Question 15

You are preparing for a network administration exam that includes both theoretical questions about protocols and practical troubleshooting scenarios.
