Enterprise Module 9.3 Queuing Algorithm

Queuing Overview: Which queuing algorithm prioritizes packets based on their arrival order?

• a) First-In, First-Out (FIFO)
• b) Weighted Fair Queuing (WFQ)
• c) Class-Based Weighted Fair Queuing (CBWFQ)
• d) Low Latency Queuing (LLQ)

Queueing Overview: Which queuing algorithm assigns weights to different flows to achieve fairness in sharing the link bandwidth?

• a) First-In, First-Out (FIFO)
• b) Weighted Fair Queuing (WFQ)
• c) Class-Based Weighted Fair Queuing (CBWFQ)
• d) Low Latency Queuing (LLQ)

Queuing Overview: Which queuing algorithm allows for the creation of traffic classes and assigns different bandwidth guarantees to each class?

• a) First-In, First-Out (FIFO)
• b) Weighted Fair Queuing (WFQ)
• c) Class-Based Weighted Fair Queuing (CBWFQ)
• d) Low Latency Queuing (LLQ)

Queuing Overview: Which queuing algorithm prioritizes delay-sensitive traffic by assigning a strict priority queue?

• a) First-In, First-Out (FIFO)
• b) Weighted Fair Queuing (WFQ)
• c) Class-Based Weighted Fair Queuing (CBWFQ)
• d) Low Latency Queuing (LLQ)

First In First Out: What is the main characteristic of First In First Out (FIFO) queuing?

• a) It buffers and forwards packets based on their priority.
• b) It assigns different classes of traffic to separate queues.
• c) It treats all packets equally and forwards them in the order of their arrival.
• d) It prioritizes time-sensitive traffic over other types of traffic

First in First Out: Which queuing strategy makes no decision about packet priority?

• a) First In First Out (FIFO)
• b) Weighted Fair Queuing (WFQ)
• c) Class-Based Weighted Fair Queuing (CBWFQ)
• d) Low Latency Queuing (LLQ)

FIFO: Which type of interfaces use FIFO queuing by default, except for serial interfaces at E1 and below?

• a) All interfaces
• b) Fast Ethernet interfaces
• c) Gigabit Ethernet interfaces
• d) Serial interfaces at E1 and below

(WFQ): What is the main purpose of Weighted Fair Queuing (WFQ)?

• a) To prioritize high-volume traffic over low-volume traffic
• b) To allocate bandwidth fairly among all network traffic
• c) To provide automated scheduling for interactive traffic
• d) To classify traffic based on packet header addressing

(WFQ): How does WFQ handle high-volume traffic flows?

• a) It drops them to prioritize low-bandwidth traffic flows.
• b) It shares the remaining capacity proportionally among them.
• c) It allocates them a fixed amount of bandwidth regardless of other flows.
• d) It prioritizes them based on their packet header addressing.

Class-Based Weighted Fair Queuing (CBWFQ): How are traffic classes defined in CBWFQ?

• a) Based on source and destination IP addresses
• b) Based on bandwidth and weight assignments
• c) Based on protocols, ACLs, and input interfaces
• d) Based on maximum packet limits and queue sizes
