Which component of a PKI is responsible for issuing and revoking digital certificates?

Certificate Revocation List (CRL)

A small business needs to encrypt files stored on a shared network drive so that only employees with the correct password can open them. The solution must be simple to manage and require minimal administrative overhead. Which approach best meets these requirements?

Apply a hash function to the files to prevent unauthorized access.

Use a symmetric encryption tool with a shared passphrase.

Use asymmetric encryption where each employee has a public and private key pair.

Deploy a full PKI with individual certificates for each employee.

What is the primary purpose of encryption in securing data?

To convert readable data into an unreadable format to protect confidentiality

To ensure that data is available whenever it is needed

To prove the identity of the sender of a message

To verify that data has not been altered during transmission

Which of the following best describes the function of encryption?

It scrambles data so that it is unreadable without the appropriate key

It ensures that data has not been modified during storage

It creates a unique digital fingerprint of data

It confirms the identity of the person sending the data
