2V0-620 Question #141: Real Exam Question with Answer & Explanation
The correct answer is D: No traffic is being sent across it because a path failed.. When a path in a multipath configuration fails, it stops carrying traffic entirely, causing apparent underutilization of available bandwidth from the ESXi host.
Section 5 – Administer and Maintain vSphere
Question
Refer to the Exhibit. A storage administrator is not seeing full utilization of all bandwidth from an ESXi host. The vSphere administrator observes the adapter details, as shown in the Exhibit. What is the probable cause of this issue?
Exhibit
Options
- AAnother path needs to be used to allow full utilization of the bandwidth.
- BThe array is not setup to use the correct multipathing policy.
- CThere are no virtual machines on the host.
- DNo traffic is being sent across it because a path failed.
Explanation
When a path in a multipath configuration fails, it stops carrying traffic entirely, causing apparent underutilization of available bandwidth from the ESXi host.
Common mistakes.
- A. Adding another path would expand total available bandwidth but does not address the root cause of a failed path carrying zero traffic as shown in the exhibit.
- B. A misconfigured multipathing policy on the array could affect load distribution across paths but would not cause a path to show zero traffic in the adapter details view.
- C. No virtual machines on the host would result in no storage I/O at all, but the scenario implies some utilization exists and the issue is that not all bandwidth is being used.
