HPE7-A08 Exam Dumps - HP Aruba Certified Switching Expert Questions and Answers

The configuration involves connecting two buildings over fiber using OM4 cabling with a distance of 200 meters. The current optics in use are 25GR (25 Gigabit Rate) optics.

For multimode fiber such as OM4, SR (Short Reach) optics are suitable for distances up to 300 meters. In contrast, LR (Long Reach) optics are typically designed for single-mode fiber and longer distances.

Therefore, to properly support the 200m OM4 fiber link, 25SR optics should be used instead of 25GR (which are often long-reach optics).

10SR and 10LR refer to 10Gbps optics, which do not meet the 25Gbps requirement.

25LR optics are for single-mode fiber and longer distances, not multimode.

When a VSX primary switch is powered off, it loses connectivity with management systems such as HPE Aruba Central. This causes the management system to trigger a "Switch Disconnected" alert because the switch is no longer reachable.

"Switch Reboot" alerts would indicate a restart, not power off.

"Switch Stack Conductor Change" refers to stack leadership changes, not VSX primary down.

"Switch STP Root Change" relates to Spanning Tree Protocol root bridge changes.

Hence, powering off the VSX primary causes a "Switch Disconnected" alert.
