Administering Windows Server 2012 Research & Evidence-Based Practice 4 — Questions and Answers
Question 1: Which PowerShell cmdlet tests network connectivity to a remote host on a specific port, replacing the deprecated Test-Connection for TCP checks on Windows Server 2012 R2?
- Test-NetConnection (Correct answer)
- Test-Connection
- netstat -an
- ping
Correct answer: Test-NetConnection
Test-NetConnection can test TCP connectivity to a specific port and returns detailed route and latency information.
Question 2: To research disk I/O bottlenecks, which Performance Monitor counter measures the average time a disk request waits in the queue before being serviced?
- Avg. Disk Queue Length (Correct answer)
- Disk Read Bytes/sec
- % Disk Time
- Current Disk Queue Length
Correct answer: Avg. Disk Queue Length
Avg. Disk Queue Length averages the number of queued read and write requests, indicating whether disk I/O is a bottleneck.
Question 3: Which Windows Server 2012 feature allows an administrator to subscribe to events from multiple remote servers and consolidate them for centralized analysis?
- Windows Event Forwarding (WEF) (Correct answer)
- Event Viewer Custom Views
- Task Scheduler event triggers
- Server Manager event alerts
Correct answer: Windows Event Forwarding (WEF)
Windows Event Forwarding uses WinRM to collect events from remote computers into a Forwarded Events log on a collector server.
Question 4: An admin needs to research memory pressure on a Hyper-V host. Which counter shows the amount of memory that has been paged to disk?
- Memory\Pages/sec (Correct answer)
- Memory\Available MBytes
- Memory\Committed Bytes
- Memory\Pool Paged Bytes
Correct answer: Memory\Pages/sec
Memory\Pages/sec measures the rate at which pages are read from or written to disk to resolve hard page faults, indicating memory pressure.
Question 5: Which command-line utility on Windows Server 2012 collects system configuration and diagnostic data into a compressed archive for support research?
- Msinfo32 /nfo (Correct answer)
- Systeminfo /fo CSV
- Winmsd
- Get-ComputerInfo
Correct answer: Msinfo32 /nfo
Msinfo32 /nfo exports a comprehensive NFO file containing hardware, OS, drivers, and running tasks for offline research.
Question 6: Which Windows Server 2012 Storage Management feature provides evidence of thin-provisioned volume usage versus allocated size?
- Storage Spaces with thin provisioning reports in Server Manager (Correct answer)
- Disk Management
- Diskpart list volume
- fsutil volume diskfree
Correct answer: Storage Spaces with thin provisioning reports in Server Manager
Storage Spaces in Server Manager shows the physical pool usage versus logical volume size, revealing thin-provisioning overhead.
Question 7: For research on DNS query resolution failures, which DNS debug log must be enabled and where is it stored by default on Windows Server 2012?
- DNS debug logging enabled in DNS Manager; stored in %SystemRoot%\System32\dns\dns.log (Correct answer)
- System event log
- Application event log
- Netsh trace ETL file
Correct answer: DNS debug logging enabled in DNS Manager; stored in %SystemRoot%\System32\dns\dns.log
DNS Server debug logging is enabled via DNS Manager's server properties and writes to dns.log in the System32\dns folder.
