Which of the following would a security specialist be able to determine upon examination of a server's certificate?

A server certificate contains the name of the issuing CA and is signed by the CA's private key, but it does not embed the CA's public key within itself.

The server's private key must remain confidential and is never included in the publicly distributed server certificate for security reasons.

A Certificate Signing Request (CSR) is the initial request submitted to a CA for a certificate and is not part of the issued certificate itself.

Object Identifiers (OIDs) are unique numerical identifiers embedded within X.509 certificates, typically found in extension fields, that specify various attributes such as certificate policies, key usage, or extended key usage. A security specialist can parse these OIDs to determine the specific purpose, features, or policies enforced during the certificate's issuance and its intended application.
