B .  High utilization of circuit-switched network resources
C .  Large packet switching delay and poor real-time transmission
D . Low packet utilization network resource utilization

View Answer

Answer:   AC

Explanation:

Circuit switching:

Advantages: small delay, transparent transmission

Disadvantages: fixed bandwidth, low network resource utilization

Packet switching:

Advantages: multiplexing, high network resource utilization

Disadvantages: large delay, poor real-time performance, and complex device functions
