Administering Windows Server 2012 Quality Control & Assurance 5 — Questions and Answers
Question 1: A QA team wants to confirm Windows Server 2012 Network Load Balancing (NLB) cluster health. Which command-line tool manages and monitors NLB clusters?
- nlbmgr or nlb.exe (Correct answer)
- netsh nlb
- clusterprop.exe
- clusterlog.exe
Correct answer: nlbmgr or nlb.exe
nlbmgr is the GUI tool and nlb.exe is the command-line tool for managing and querying NLB cluster status.
Question 2: During QA, a Windows Server 2012 R2 server is found to have excessive page file usage. Which Performance Monitor counter set should an analyst review first?
- Memory\Pages/sec and Paging File\% Usage (Correct answer)
- Processor\% Processor Time
- PhysicalDisk\Avg. Disk Queue Length
- Network Interface\Bytes Total/sec
Correct answer: Memory\Pages/sec and Paging File\% Usage
Memory\Pages/sec measures paging activity and Paging File\% Usage shows how much of the page file is in use, together indicating memory pressure.
Question 3: A QA engineer needs to verify that a Windows Server 2012 DHCP server is not issuing duplicate IP addresses. Which DHCP server feature detects conflicts before leasing an address?
- DHCP Conflict Detection (ping attempts) (Correct answer)
- DHCP Failover

Correct answer: DHCP Conflict Detection (ping attempts)
DHCP Conflict Detection sends ICMP pings before issuing a lease; if a reply comes back, the address is marked as conflicted.

- dism /Online /Cleanup-Image /RestoreHealth (Correct answer)
- dism /Online /Get-Features
- dism /Online /Enable-Feature
- dism /Image:C:\ /ScanHealth
Correct answer: dism /Online /Cleanup-Image /RestoreHealth
dism /Online /Cleanup-Image /RestoreHealth contacts Windows Update (or a supplied source) to repair a corrupted component store.
Question 5: A QA checklist requires confirming that Windows Server 2012 auditing is configured to log both successful and failed logon attempts. In which policy node is this configured?
- Security Settings > Advanced Audit Policy Configuration > Logon/Logoff (Correct answer)
- Security Settings > Software Restriction Policies
- Windows Settings > Scripts
- Administrative Templates > System > Logon
Correct answer: Security Settings > Advanced Audit Policy Configuration > Logon/Logoff
Advanced Audit Policy Configuration under Security Settings provides granular audit subcategories including Logon and Logoff success/failure.
Question 6: When validating a Windows Server 2012 storage pool in a QA environment, which PowerShell cmdlet retrieves the health status of all physical disks in the pool?
- Get-PhysicalDisk | Select FriendlyName,HealthStatus (Correct answer)
- Get-Disk | Select OperationalStatus
- Get-StoragePool | Select HealthStatus
- Get-VirtualDisk | Select HealthStatus
Correct answer: Get-PhysicalDisk | Select FriendlyName,HealthStatus
Get-PhysicalDisk returns each disk's HealthStatus property, indicating Healthy, Warning, or Unhealthy state.
Question 7: A QA process requires verifying that Windows Server 2012 event logs are not silently overwriting old entries. Which event log setting retains old logs by requiring manual archiving?
- Archive the log when full, do not overwrite events (Correct answer)
- Overwrite events as needed (oldest events first)
- Do not overwrite events (Clear logs manually)
