70-413 Exam Quality Control & Assurance 4

Question 1

Your QA process mandates that all virtual machine checkpoints are removed before a VM enters production. Which risk does retaining checkpoints in a production Hyper-V environment pose?

Accepted Answer

AVHD differencing disks grow unbounded and can exhaust storage

Answer

Each Hyper-V checkpoint creates an AVHD differencing disk that grows as writes accumulate; in production, this can rapidly consume storage and degrade I/O performance.

Question 2

A deployment validation test requires confirming that NIC teaming is correctly load-balancing traffic across both physical adapters. Which PowerShell cmdlet displays real-time traffic statistics per team member NIC?

Accepted Answer

Get-NetAdapterStatistics

Answer

Get-NetAdapterStatistics returns per-adapter packet and byte counters that you can compare across team member NICs to verify load distribution is occurring.

Question 3

A QA engineer needs to validate that iSCSI LUNs provisioned to a Windows Server 2012 R2 host are correctly aligned to 4K physical sector boundaries. Which tool identifies partition alignment on presented storage?

Accepted Answer

WMI query on Win32_DiskPartition StartingOffset

Answer

Querying Win32_DiskPartition.StartingOffset via WMI reveals the byte offset of each partition; dividing by 4096 (or 1MB) confirms alignment to physical sector boundaries.

Question 4

During load testing of a new IIS-based internal application server, you need to generate realistic HTTP request loads. Which built-in Windows Server tool can simulate concurrent web requests for performance validation?

Accepted Answer

Web Capacity Analysis Tool (WCAT)

Answer

WCAT (Web Capacity Analysis Tool) is a Microsoft tool that generates configurable HTTP/HTTPS load against IIS to validate throughput, latency, and failure behavior under stress.

Question 5

A change control process requires that all server OS deployments be performed from approved WDS images only. Which WDS feature prevents technicians from booting into unapproved images?

Accepted Answer

Require administrator approval for all PXE connections

Answer

Enabling the 'Require administrator approval' option in WDS forces all PXE boot requests to queue for manual approval, preventing unauthorized or unapproved image deployments.
