Homework is due at 12:30 PM on 5/5/2025
Q1. (T/F) The link-layer operates on a hop-by-hop transmission basis. True or False? (1 point)
Q2. (T/F) Routers use IP addresses to make routing decisions, while switches use MAC addresses. True or
False? (1 point)
Q3. (T/F) MAC addresses follow a hierarchical addressing structure. True or False? (1 point)
Q4. (T/F) Channel partitioning protocol can achieve 100% utilization, in the case that there is only one
node that always has frames to send. True or False? (1 point)
Q5. (T/F) Random access protocols can achieve 100% channel utilization, assuming all nodes always have
frames to send, without encountering collisions. True or False? (1 point)
Q6. Consider the following multiple access protocols.
Which of these protocols is NOT collision-free? (2 points)
1) Polling
2) CSMA (Carrier Sense Multiple Access)
3) TDMA (Time Division Multiple Access)
4) FDMA (Frequency Division Multiple Access)
Q7. Which of the following statements is true about the relationship between VLANs and broadcast
domains? (2 points)
1) VLANs have no impact on broadcasting domains; they only affect collision domains.
2) All VLANs share a single broadcasting domain, leading to increased broadcast traffic.
3) Each VLAN creates a separate broadcasting domain, reducing broadcast traffic within the
network.
4) VLANs are only relevant for managing switch ports and have no effect on network performance.
Q8. Each switch has a switch table, and each entry consists of 1) MAC address of host, 2) interface to
reach host, and 3) time stamp.
How are switching entries created and maintained in switch table? (1 point)
1) Via BGP protocol
2) Via Dijkstra protocol
3) Via ARP protocol
4) Via self-learning
