2V0-620 Question #102: Real Exam Question with Answer & Explanation
The correct answer is C: Not all links are used because a path is disabled.. A disabled storage path prevents the ESXi host from distributing I/O across all available links, resulting in less than full bandwidth utilization.
Section 2 – Administer vSphere Resources
Question
Refer to the Exhibit. A storage administrator has reported that full utilization of all bandwidth from an ESXi 6.x host is not being seen. In troubleshooting the issue, the Adapter details are shown in the Exhibit. Based on the exhibit, what is cause of the issue?
Exhibit
Options
- AThe array is not setup to use the correct multipathing policy.
- BThere are no virtual machines on the ESXi host.
- CNot all links are used because a path is disabled.
- DAnother path needs to be configured.
Explanation
A disabled storage path prevents the ESXi host from distributing I/O across all available links, resulting in less than full bandwidth utilization.
Common mistakes.
- A. The multipathing policy controls how I/O is distributed across active paths, but it does not disable paths; a policy misconfiguration would not show a path as disabled in the adapter details.
- B. The presence or absence of virtual machines does not affect whether storage paths are active or disabled at the host adapter level.
- D. The exhibit shows existing paths are present but one is disabled, not that the path count is insufficient; adding another path would not re-enable the already-configured disabled path.
