Question 173 of 144
SK0-005 troubleshooting Practice Question
A server's performance degrades significantly during peak usage hours. Monitoring shows high memory utilization and consistently high disk I/O. Which of the following should the technician check FIRST?
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
✓
Page file location and configuration
Option B is correct because high memory usage and heavy disk I/O suggest excessive paging. Checking the page file location and its performance (e.g., on a slow disk) is the first step to diagnose paging bottlenecks. Option A is less likely if CPU is not a known issue. Option C would typically cause different symptoms. Option D is unrelated to immediate memory/disk correlation.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
RAID controller battery status
Why it's wrong here
A failed battery could disable write caching, causing slower writes, but wouldn't directly explain high memory usage.
- ✗
Network bandwidth utilization
Why it's wrong here
Network issues would manifest as slow file transfers or connectivity problems, not high disk I/O and memory pressure.
- ✗
CPU utilization statistics
Why it's wrong here
High CPU is possible but the description points to memory and disk I/O, not processor bottlenecks.
- ✓
Page file location and configuration
Why this is correct
When physical memory is overcommitted, the server pages to disk; poor page file placement can cause high I/O and slow performance.
