Microsoft Networking Essentials Exam Research & Evidence-Based Practice 5 — Questions and Answers
Question 1: Which approach represents evidence-based practice when planning a network upgrade to support higher bandwidth requirements?
- Upgrade all hardware to the latest model immediately
- Analyze current utilization trends and project future needs using historical data (Correct answer)
- Ask users which applications feel slow
- Follow the same plan as a competitor company
Correct answer: Analyze current utilization trends and project future needs using historical data
Analyzing utilization trends and projecting from historical data provides objective, evidence-based justification for upgrade decisions rather than assumption.
Question 2: When researching whether to implement 802.11ax (Wi-Fi 6) in an enterprise environment, which source provides the most authoritative technical specifications?
- Social media technology influencers
- The IEEE 802.11ax standard document published by IEEE (Correct answer)
- Product marketing brochures
- End-user reviews on retail websites
Correct answer: The IEEE 802.11ax standard document published by IEEE
IEEE standards documents are the authoritative technical specifications defining the exact capabilities, requirements, and behaviors of wireless networking standards.
Question 3: What is the evidence-based purpose of conducting a 'post-mortem' after a network outage?
- To assign blame to the responsible team member
- To document root cause, timeline, and corrective actions to prevent recurrence (Correct answer)
- To satisfy vendor warranty requirements
- To generate reports for external auditors only
Correct answer: To document root cause, timeline, and corrective actions to prevent recurrence
Post-mortems use collected evidence to identify root cause, build an accurate timeline, and define corrective actions that prevent the same failure from recurring.
Question 4: A technician uses 'netstat -e' to collect evidence about network interface statistics. What category of data does this command provide?
- Active TCP connection states and port numbers
- Ethernet interface statistics including bytes sent, received, and errors (Correct answer)
- DNS cache entries and TTL values
- Routing table entries and next-hop addresses
Correct answer: Ethernet interface statistics including bytes sent, received, and errors
The '-e' flag displays Ethernet statistics including bytes and packets sent/received and interface errors, providing evidence of interface-level health.
Question 5: In network research, what does the term 'reproducibility' mean in the context of troubleshooting findings?
- The ability to copy a network configuration to multiple devices
- The ability to consistently recreate an observed problem under the same conditions (Correct answer)
- Restoring a backup configuration from archive
- Duplicating a server for high availability
Correct answer: The ability to consistently recreate an observed problem under the same conditions
Reproducibility means consistently recreating the problem under controlled conditions, which validates that the evidence is genuine and the identified cause is correct.
Question 6: Which Microsoft Windows Server role provides centralized, evidence-based logging for network access control events across multiple servers?
- DNS Server
- Network Policy Server (NPS) (Correct answer)
- DHCP Server
- Print and Document Services
Correct answer: Network Policy Server (NPS)
Network Policy Server logs all RADIUS authentication and authorization events centrally, providing a consolidated evidence source for network access auditing.
Question 7: When evaluating two competing network topology designs using evidence-based methods, which criterion provides the most objective comparison?
- Which design looks simpler on paper
- Measured performance against defined SLAs and quantified risk scores for each design (Correct answer)
- The personal preference of the senior engineer
- Which design uses more familiar equipment brands
Correct answer: Measured performance against defined SLAs and quantified risk scores for each design
Measuring against defined SLAs and quantifying risk provides objective, reproducible criteria that remove personal bias from design decisions.
