What is a recommended best practice when implementing encryption for data at rest?

Disable encryption on backup systems to improve performance

Encrypt only the most sensitive files to save processing time

Use the same encryption algorithm for all data, regardless of sensitivity

Use strong, industry-standard encryption algorithms and manage keys securely

A company is deploying a new remote access solution for employees. The solution must support both encrypted communication and strong user authentication. Which combination of protocols best meets these requirements?

HTTPS for encryption and usernames for authentication

SSH for encryption and shared secrets for authentication

TLS for encryption and certificates for authentication

IPsec for encryption and passwords for authentication

An organization wants to deploy a web server that uses HTTPS. To ensure that clients can trust the server's identity, the organization obtains a certificate from a well-known certificate authority (CA). What is the primary role of the CA in this scenario?

To vouch for the identity of the web server by issuing a digitally signed certificate

To provide a backup of all encrypted data

To encrypt all traffic between the client and the server

To store the server's private key securely

A system administrator wants to verify that a configuration file has not been altered since it was last backed up. The administrator has the original hash of the file. What should the administrator do?

Encrypt the current file and compare it to the original

Recalculate the hash of the current file and compare it to the original

Restore the file from backup and assume it is correct

Use a digital signature to verify the file's origin
