STP Concepts

Which of the following best describes the purpose of the Spanning Tree Protocol (STP)?

• A) To assign IP addresses to devices in a network.
• B) To create a loop-free Layer 2 topology while allowing for redundancy.
• C) To enhance the speed of data transmission in an Ethernet network.
• D) To encrypt data frames for secure transmission across a network.

What can a Layer 2 loop result in?

• A) Stable MAC address tables.
• B) MAC address table instability.
• C) Reduced broadcast storms.
• D) Improved CPU utilization on switches.

Which issue might arise from redundant paths in a switched Ethernet network if not properly managed?

• A) Enhanced security measures.
• B) Faster data transmission.
• C) Physical and logical Layer 2 loops.
• D) Increased network uptime.

Why do Ethernet LANs require a loop-free topology?

• A) To ensure high data latency.
• B) To provide multiple paths between devices.
• C) To prevent endlessly looping frames.
• D) To prioritize frame transmission.

What is a potential consequence of Layer 2 loops in the absence of STP?

• A) Reduced network congestion.
• B) Broadcast storm.
• C) Improved MAC address table stability.
• D) Enhanced security.

Who invented the spanning tree algorithm (STA) that STP is based on?

• A) Linus Torvalds.
• B) Tim Berners-Lee.
• C) Radia Perlman.
• D) Robert E. Kahn.

Which of the following determines the switch that becomes the root bridge in the STP process?

• a. The switch with the highest MAC address.
• b. The switch that was powered on first.
• c. The switch with the highest BID.
• d. The switch with the lowest BID.

If two switches have the same priority, which criteria is used to determine the root bridge?

• a. The switch's location.
• b. The switch with the most ports.
• c. The switch with the lowest MAC address.
• d. The switch with the highest MAC address

Which of the following is NOT a port state in RSTP?

• A) Learning
• B) Forwarding
• C) Blocking
• D) Discarding
