MD-100 100: Network Configuration 2 — Questions and Answers
Question 1: A Windows 10 laptop connects to a corporate Wi-Fi network but cannot reach the internet. The IP address shown is 169.254.x.x. What is the most likely cause?
- The DHCP server is unreachable or not responding (Correct answer)
- The Wi-Fi password is incorrect
- The default gateway is misconfigured manually
- DNS resolution has failed
Correct answer: The DHCP server is unreachable or not responding
A 169.254.x.x address is an APIPA address assigned automatically when the DHCP server cannot be reached.
Question 2: Which command releases and renews a DHCP lease on a Windows 10 client in the correct order?
- ipconfig /release then ipconfig /renew (Correct answer)
- ipconfig /renew then ipconfig /release
- ipconfig /flushdns then ipconfig /renew
- netsh interface reset then ipconfig /renew
Correct answer: ipconfig /release then ipconfig /renew
You must release the current lease before renewing to obtain a new IP address from the DHCP server.
Question 3: A user needs to configure a static IP address on their Windows 10 PC. Where in the Settings app is this configured?
- Settings > Network & Internet > Status > Change adapter options > Adapter Properties > IPv4 Properties (Correct answer)
- Settings > System > About > Network Properties
- Settings > Update & Security > Network
- Settings > Privacy > Network Access
Correct answer: Settings > Network & Internet > Status > Change adapter options > Adapter Properties > IPv4 Properties
Static IP settings are configured under IPv4 Properties within the adapter's network settings.
Question 4: Which Windows 10 feature allows a device to share its cellular data connection with other devices over Wi-Fi?
- Mobile Hotspot (Correct answer)
- Network Bridge
- Wi-Fi Direct
- Airplane Mode
Correct answer: Mobile Hotspot
Mobile Hotspot in Windows 10 shares an internet connection (including cellular) with nearby Wi-Fi devices.
Question 5: A technician needs to test connectivity to a specific port on a remote server from a Windows 10 PC. Which command is most appropriate?
- Test-NetConnection -ComputerName server -Port 443 (Correct answer)
- ping server -p 443
- tracert server:443
- netstat -a server 443
Correct answer: Test-NetConnection -ComputerName server -Port 443
Test-NetConnection with the -Port parameter tests TCP connectivity to a specific port on a remote host.
Question 6: Which IPv6 address type is equivalent to an IPv4 private address and is routable only within a local network?
- Unique Local Address (ULA) fc00::/7 (Correct answer)
- Link-Local Address fe80::/10
- Global Unicast Address 2000::/3
- Multicast Address ff00::/8
Correct answer: Unique Local Address (ULA) fc00::/7
Unique Local Addresses (ULA) in the fc00::/7 range are the IPv6 equivalent of IPv4 private addresses.
Question 7: A Windows 10 PC has two network adapters. A user wants all traffic to use the faster wired adapter. What should be adjusted?
- Interface metric — set the wired adapter to a lower metric value (Correct answer)
- Disable the wireless adapter permanently
- Change the MTU on the wireless adapter
- Assign the wired adapter a higher IP address
Correct answer: Interface metric — set the wired adapter to a lower metric value
A lower interface metric value gives an adapter higher routing priority, so Windows prefers it for traffic routing.
