Refer to the exhibit. An administrator notices that two uplinks are down on the VDS. Which step should be taken first to restore redundancy?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Check the physical switch ports and cables for uplink2 and uplink3.
A vSphere Distributed Switch tracks uplink state per physical NIC, and when two uplinks show down, the likely cause is Layer 1 — cable, SFP, or switch port failure — rather than a vDS configuration issue. Checking physical switch ports and cabling first follows the OSI bottom-up troubleshooting model and avoids unnecessary configuration changes. The vDS itself does not 'disable' individual uplinks; they appear down because the physical link is down. Increasing MTU or removing uplinks would mask the symptom without restoring redundancy. In production, a vDS with four uplinks and two down still forwards traffic via the remaining pair, but failover capacity is halved, so verifying physical connectivity before touching teaming or LACP policy is the correct first step.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Check the physical switch ports and cables for uplink2 and uplink3.
Why this is correct
Physical connectivity issues are the most common cause of down uplinks.
- ✗
Increase the MTU to 9000 to improve performance.
Why it's wrong here
MTU change does not affect link status.
- ✗
Disable LACP on the VDS to allow single-uplink operation.
Why it's wrong here
LACP is not causing the down state.
- ✗
Remove the down uplinks from the VDS.
Why it's wrong here
Removing uplinks would reduce redundancy further.
