Comprehensive and Detailed Explanation From Exact Extract:

To verify that the certificate and the private key match, one can extract the modulus from both files and compare their hash values. The correct syntax involves using openssl x509 to extract the modulus from the certificate, and openssl rsa to extract the modulus from the private key, followed by an MD5 hash to ensure they match.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “TLS/SSL Certificate Validation and Troubleshooting”:

“To verify that the private key and certificate match, compare the modulus values. A mismatch results in failed TLS handshakes.”

Other options:

A & C: Incorrect syntax (openssl-list and openssl-rsa are not valid commands).

B: The commands shown are used to verify CSRs, not matching keys.

================================================

Comprehensive and Detailed Explanation From Exact Extract:

A 403 Forbidden error indicates that the request was understood by the server but is refusing to fulfill it due to insufficient authorization. The developer is attempting to call a protected API that requires valid credentials such as an access key and signature (often used in HMAC-based APIs), but the values appear as Postman variables (e.g., {{rapyd_access_key}}), which suggests they were not replaced with actual credentials.

This typically means that the request lacks proper authentication or authorization headers, or the keys/signature are incorrect or missing. The presence of access_key, signature, salt, and timestamp in the request implies the API requires authentication, but the variables were not resolved or valid.

Relevant Extract from CompTIA CloudNetX CNX-001 Study Guide — under “API Security and Authentication”:

“A 403 error typically results from failed authentication or lack of proper authorization. Developers must ensure that tokens or signatures are valid, not missing, and properly injected.”

Other options:

A. 404 is the code for a missing resource, not 403.

C. A firewall rule would block the request entirely (e.g., no response or a 0 status), not result in a 403 from the server.

D. HTTP redirection issues typically result in 3xx codes, not 403.
