CompTIA A+ Core 1 (220-1001) — Question 338

A technician recently installed a new router. Since the installation was completed, a user's PC loses network connectivity when another user's PC comes online.
Which of the following commands are BEST for the technician to run to resolve this issue? (Choose two.)

Answer options

• A. ipconfig / renew
• B. ipconfig / all
• C. ipconfig / flushdns
• D. ipconfig / registerdns
• E. ipconfig / release
• F. ipconfig / displaydns

Correct answer: A, E

Explanation

The commands 'ipconfig / renew' and 'ipconfig / release' are effective in troubleshooting connectivity issues as they help in renewing the IP address and releasing the current one, respectively. Other options like 'ipconfig / all', 'ipconfig / flushdns', 'ipconfig / registerdns', and 'ipconfig / displaydns' do not directly address the conflict caused by the new router installation.
