Question 42 of 144
SK0-005 troubleshooting Practice Question
A server that uses iSCSI storage has suddenly lost connectivity to all LUNs. The network team confirms no changes have been made. Which of the following is the FIRST step in troubleshooting this 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
✓
Verify the status of the iSCSI initiator service on the server.
Option A is correct because the iSCSI initiator service must be running to connect to targets; verifying its status is a quick, non-disruptive first check on the local server. Option B: replacing cables is premature when there are no network changes and problem is confined to this server. Option C: changing the IP address would likely break other services. Option D: VLAN issues would normally affect multiple devices and are less likely if the network team reports no changes.
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 VLAN configuration on the switch.
Why it's wrong here
VLAN changes would typically affect multiple devices; given no network changes, this is less likely than a server-local issue.
- ✗
Replace the network cables to the storage array.
Why it's wrong here
Without evidence of physical damage and no changes on the switch, this is not the first step.
- ✓
Verify the status of the iSCSI initiator service on the server.
Why this is correct
A stopped or failed initiator service would immediately sever all iSCSI connections, making this the logical first check.
- ✗
Reconfigure the IP address of the server.
Why it's wrong here
Reconfiguring the IP may cause additional connectivity problems and should not be done without isolating the cause.
