Which of the following is a symmetric encryption algorithm?

  1. RSA

  2. AES

  3. ECC

  4. DES

Show answer
Correct Option: B
Explanation:

AES (Advanced Encryption Standard) is a symmetric encryption algorithm that uses the same key for encryption and decryption.

What is the purpose of a key management system (KMS) in cloud security encryption?

  1. To generate and manage encryption keys

  2. To store encrypted data

  3. To provide access control to encrypted data

  4. To perform encryption and decryption operations

Show answer
Correct Option: A
Explanation:

A key management system (KMS) is responsible for generating, storing, and managing encryption keys used to protect data in the cloud.

Which of the following is a type of encryption key used in cloud security?

  1. Symmetric key

  2. Asymmetric key

  3. Public key

  4. Private key

Show answer
Correct Option: A
Explanation:

Symmetric keys are used in symmetric encryption algorithms, where the same key is used for both encryption and decryption.

What is the primary benefit of using asymmetric encryption in cloud security?

  1. Improved performance

  2. Enhanced security

  3. Simplified key management

  4. Reduced computational overhead

Show answer
Correct Option: B
Explanation:

Asymmetric encryption provides enhanced security by using different keys for encryption and decryption, making it more difficult for unauthorized parties to access encrypted data.

Which of the following is a best practice for managing encryption keys in the cloud?

  1. Store keys in plain text

  2. Use weak encryption algorithms

  3. Rotate keys regularly

  4. Share keys with multiple users

Show answer
Correct Option: C
Explanation:

Rotating encryption keys regularly helps to protect data from compromise in case a key is compromised.

What is the primary purpose of using encryption in cloud security?

  1. To improve data integrity

  2. To enhance data availability

  3. To protect data confidentiality

  4. To reduce data redundancy

Show answer
Correct Option: C
Explanation:

Encryption is primarily used in cloud security to protect data confidentiality by rendering it unreadable to unauthorized parties.

Which of the following is a common encryption algorithm used for data at rest in the cloud?

  1. AES-256

  2. RSA-2048

  3. ECC-521

  4. SHA-256

Show answer
Correct Option: A
Explanation:

AES-256 is a widely used symmetric encryption algorithm that is commonly employed to protect data at rest in the cloud.

What is the term used to describe the process of converting plaintext into ciphertext?

  1. Encryption

  2. Decryption

  3. Hashing

  4. Encoding

Show answer
Correct Option: A
Explanation:

Encryption is the process of converting plaintext into ciphertext, making it unreadable to unauthorized parties.

Which of the following is a type of encryption that uses a single key for both encryption and decryption?

  1. Symmetric encryption

  2. Asymmetric encryption

  3. Public key encryption

  4. Private key encryption

Show answer
Correct Option: A
Explanation:

Symmetric encryption uses a single key for both encryption and decryption, making it more efficient than asymmetric encryption.

What is the term used to describe the process of converting ciphertext back into plaintext?

  1. Encryption

  2. Decryption

  3. Hashing

  4. Encoding

Show answer
Correct Option: B
Explanation:

Decryption is the process of converting ciphertext back into plaintext, making it readable to authorized parties.

Which of the following is a type of encryption that uses two different keys for encryption and decryption?

  1. Symmetric encryption

  2. Asymmetric encryption

  3. Public key encryption

  4. Private key encryption

Show answer
Correct Option: B
Explanation:

Asymmetric encryption uses two different keys for encryption and decryption, providing enhanced security compared to symmetric encryption.
