Developing Applications Using Cisco Core Platforms and APIs (DEVCOR) — Question 74

A team of developers created their own CA and started signing certificates for all of their IoT devices.
Which action will make the browser accept these certificates?

Answer options

• A. Install a TLS instead of SSL certificate on the IoT devices.
• B. Set the private keys 1024-bit RSA.
• C. Preload the developer CA on the trusted CA list of the browser.
• D. Enable HTTPS or port 443 on the browser.

Correct answer: C

Explanation

The correct answer is C because for the browser to trust the certificates signed by the developers' CA, the CA must be included in the browser's trusted CA list. Options A, B, and D do not address the need for trust in the CA itself, which is essential for the browser to accept the certificates.
