Question 50 of 144
SK0-005 server-administration Practice Question
A server has two NICs configured in a team using LACP. The server loses network connectivity when one NIC is physically disconnected, even though both links show as active in the teaming software before the failure. What is the most likely cause of the issue?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
LACP is not correctly configured on the switch
For LACP to work properly, the switch must be explicitly configured to bundle the ports into a port channel. If the switch is not configured for LACP, it may not handle the failover correctly, causing a loss of connectivity when one link drops. NIC driver issues or STP are less likely to cause this specific symptom, and setting the team to Switch Independent would not use LACP.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
LACP is not correctly configured on the switch
Why this is correct
Without the switch-side LACP configuration, the switch treats the links as independent, and removing one may cause the remaining link to be unable to carry traffic, leading to connectivity loss.
- ✗
The teaming mode is set to 'Switch Independent' instead of LACP
Why it's wrong here
The scenario explicitly states LACP is being used; if it were Switch Independent, the team would not require LACP and would handle failover differently, but this contradicts the given information.
- ✗
Spanning Tree Protocol is blocking the failover path
Why it's wrong here
STP might temporarily block a port during topology changes, but it would not consistently cause loss of all connectivity after a NIC failure in a properly configured LACP team.
- ✗
NIC driver version mismatch between the two adapters
Why it's wrong here
While a mismatch could cause instability, it typically does not result in complete loss of connectivity during a failover event if LACP is properly configured.
