Step-by-Step Solution
Solution:
Step 1: Understand monitoring frequency
Checking CPU every 5 minutes requires a loop with a 300-second (5-minute) sleep between checks.Step 2: Use Get-Counter and conditional email
Get-Counter can measure CPU usage; if usage > 80%, Send-MailMessage sends alert.Step 3: Evaluate options
Use a loop with Start-Sleep 300, check CPU with Get-Counter, send email if over 80% uses loop with Start-Sleep 300 and conditional email, matching requirements. Others either run once or wrong intervals.Final Answer:
Use a loop with Start-Sleep 300, check CPU with Get-Counter, send email if over 80% -> Option AQuick Check:
Loop + 5 min sleep + CPU check + email = C [OK]
Quick Trick: Loop with 300s sleep and conditional email alert [OK]
Common Mistakes:
- Running check only once without loop
- Using wrong sleep duration
- Confusing scheduled task frequency with script loop
