Dell EMC Specialist – Systems Administrator, VMAX All Flash and PowerMax — Question 20

An implementation engineer is installing ECS and sees that node names are not resolving to the public IP address. Which command should they use to validate the ECS DNS configuration?

Answer options

• A. cat /etc/resolv.conf
• B. getrackinfo -r
• C. ifconfig
• D. nslookup

Correct answer: B

Explanation

The correct command to validate the ECS DNS configuration is 'getrackinfo -r' (Option B), as it specifically checks the DNS settings related to ECS. The other options, while useful for different purposes, do not directly address the validation of the DNS configuration for ECS. For example, 'nslookup' (Option D) is generally used for querying DNS records but does not validate the ECS-specific settings.
