MCTS 70-642 Quality Control & Assurance 2 — Questions and Answers
Question 1: You need to capture a baseline of network traffic on a Windows Server 2008 system before a major application deployment. Which built-in tool provides the most comprehensive data collector set for this purpose?
- Network Monitor 3.4
- Reliability and Performance Monitor (Correct answer)
- Event Viewer
- Netstat
Correct answer: Reliability and Performance Monitor
Reliability and Performance Monitor in Windows Server 2008 allows you to create Data Collector Sets that capture performance counters, event traces, and configuration data for baseline analysis.
Question 2: A network administrator notices intermittent packet loss on a segment. Which Windows Server 2008 command-line tool provides hop-by-hop latency to isolate where packet loss occurs?
- ping
- pathping (Correct answer)
- tracert
- netstat
Correct answer: pathping
Pathping combines ping and tracert functionality, computing packet loss and latency statistics at each hop over a period of time.
Question 3: Which performance object in Windows Server 2008 Performance Monitor should you monitor to assess network interface saturation?
- Network Interface\Bytes Total/sec (Correct answer)
- TCPv4\Connections Established
- Server\Bytes Total/sec
- IPv4\Datagrams/sec
Correct answer: Network Interface\Bytes Total/sec
Network Interface\Bytes Total/sec shows total throughput on the adapter; comparing it against interface speed reveals saturation.
Question 4: You want to ensure that a DHCP server is not issuing duplicate IP addresses after a scope change. Which tool quickly identifies active IP-to-MAC mappings on the local subnet?
- ipconfig /all
- arp -a (Correct answer)
- netstat -an
- nslookup
Correct answer: arp -a
The arp -a command displays the ARP cache, showing IP addresses and their associated MAC addresses resolved on the local subnet.
Question 5: An organization's SLA requires 99.9% uptime for a file server. Which Windows Server 2008 feature most directly helps you detect and alert on service availability failures before users call the help desk?
- Task Scheduler
- Performance Monitor Alerts (Correct answer)
- Server Manager event subscriptions
- Windows Error Reporting
Correct answer: Performance Monitor Alerts
Performance Monitor Alerts trigger notifications or actions when a counter crosses a defined threshold, enabling proactive detection of availability issues.
Question 6: During a QA audit, you must verify that all DNS zone transfers are restricted to authorized secondary servers. Which DNS Server property page contains this setting in Windows Server 2008?
- Forwarders tab
- Zone Transfers tab (Correct answer)
- Advanced tab
- Security tab
Correct answer: Zone Transfers tab
The Zone Transfers tab on a DNS zone's properties allows you to restrict zone transfers to specific IP addresses or named servers.
Question 7: You are reviewing QA logs and find that a WINS server is registering stale records. What is the recommended first action to correct this without disrupting active registrations?
- Stop and restart the WINS service
- Run tombstoning on stale records (Correct answer)
- Delete and recreate the WINS database
- Increase the renewal interval
Correct answer: Run tombstoning on stale records
Tombstoning marks stale records for deletion and replicates the tombstone state to partner servers, ensuring consistent removal without disrupting active registrations.
