Question 1

In an InfiniBand fabric, you are tasked with designing a QoS policy using Virtual Lanes (VLs) to segregate traffic types. Which of the following best describes how VLs should be configured for optimal traffic management?

A : Use only two Virtual Lanes: one for high-priority traffic and one for low-priority traffic, as InfiniBand guarantees low latency for all traffic.

B : Assign a separate VL for each traffic type, ensuring that critical traffic such as management traffic is isolated from application data traffic.

C : Use a single Virtual Lane (VL) for all traffic types to reduce configuration overhead and complexity.

D : Assign bandwidth-heavy traffic and latency-sensitive traffic to the same VL to maximize network resource utilization.

Answer: B

Question 2

You are configuring an InfiniBand fabric to optimize high-throughput, low-latency communication for a large-scale HPC cluster. Which advanced InfiniBand feature allows you to ensure traffic prioritization and reduce congestion for critical workloads?

A : Multipathing (MPIO)

B : Adaptive Routing (AR)

C : Credit-Based Flow Control

D : Service Level (SL) to Virtual Lane (VL) Mapping

Answer: D

Question 3

In InfiniBand, Virtual Lanes (VLs) are used to provide logical isolation of traffic within a single physical connection. What is the maximum number of Virtual Lanes supported by the InfiniBand standard, and what is their primary purpose?

A : 4 Virtual Lanes, used for low-latency traffic

B : 8 Virtual Lanes, used for data traffic prioritization only

C : 16 Virtual Lanes, with all used for data transmission

D : 15 Virtual Lanes, with one reserved for management traffic

Answer: D

Question 4

Which feature of InfiniBand makes it particularly suitable for applications like artificial intelligence (AI) and machine learning (ML) workloads?

A : Remote Direct Memory Access (RDMA) for reduced CPU load and fast data transfer

B : High compatibility with legacy Ethernet switches

C : Support for Quality of Service (QoS) to prioritize traffic

D : Built-in firewall and network security features

Answer: A

Question 5

You notice performance degradation in your InfiniBand fabric, particularly when multiple large datasets are being transferred simultaneously. You run diagnostic tools but do not detect obvious hardware failures. Which diagnostic technique would most likely reveal the source of this issue?

A : Inspecting Congestion Control Mechanisms

B : Checking Port Error Counters for CRC Errors

C : Testing QP (Queue Pair) Depth

D : Verifying Link Initialization

Answer: A
