Answer 1

Question 1: Answer: True

Explanation: It is true that the Ethernet frame format (IEEE 802.3)  has remained unchanged since the first standard; even though, the cables and the wiring scheme have changed dramatically.

Question 2: Answer: Option A: VLAN switch

Explanation:

The concept of a VLAN (Virtual Local Area Network) switch is allow a switch to be configured to emulate multiple, independent switches.

Question 3: Answer: True

Explanation:

A Virtual Local Area Network (VLAN) switch allows the switch to be reconfigured to emulate multiple, independent switches. as per the question 2.

Question 4: Answer: Option B: multiple VLAN switches to be interconnected and to operate like a giant VLAN switch.

Explanation:

IEEE 802.1Q, is the networking standard that supports virtual LANs (VLANs) on an IEEE 802.3 Ethernet network

Question 5: Answer: Option C: prevent broadcast messages from flowing in an endless loop.

Explanation:

The purpose of a Distributed Spanning Tree (DST) is to prevent broadcast messages from flowing in an endless loop.
