[All CV0-004 Questions]

An DevOps engineer is receiving reports that users can no longer access the company's web application after hardening of a web server. The users are receiving the following error:

ERR_SSLJ/ERSION_OR_CIPHER_MISMATCH.

Which of the following actions should the engineer take to resolve the issue?

Show Suggested Answer Hide Answer
Suggested Answer: B

To resolve the ERR_SSL_VERSION_OR_CIPHER_MISMATCH error after hardening a web server, the engineer should configure the server to use TLS 1.2 or newer. This error often occurs when the server or client supports an outdated version of SSL/TLS or incompatible cipher suites. Updating to a modern, secure version of TLS ensures compatibility and enhances security.

: The CompTIA Cloud+ certification includes governance, risk, compliance, and security for the cloud, emphasizing the importance of implementing up-to-date security protocols like TLS to protect data in transit and ensure secure communications in cloud environments.

Wait, are we sure it's not a cipher mismatch? Sounds weird.

Restarting the server (A) won't fix this, just a waste of time.

Updating the web server seems like a good idea, but I wonder if that alone would resolve the cipher mismatch error.

This reminds me of a practice question where we had to troubleshoot SSL errors. I think reviewing the logs on the WAF could provide some insights too.

I'm not entirely sure, but I feel like restarting the web server wouldn't really fix a cipher mismatch issue.

I remember studying about SSL/TLS configurations, and I think enabling TLS 1.2 or newer might be the key here.
