To preserve the confidentiality of data

c.

To create ciphertext metadata

d.

To establish trust boundaries

Discuss
Answer: (b).To preserve the confidentiality of data Explanation:The primary purpose of the encryption mechanism is to preserve the confidentiality and integrity of data by encoding plaintext into a protected and unreadable format.
Q2.
What is the term for the unreadable format into which plaintext data is transformed using encryption?

a.

Secret text

b.

Coded data

c.

Ciphertext

d.

Encoded text

Discuss
Answer: (c).Ciphertext Explanation:The unreadable format into which plaintext data is transformed using encryption is called ciphertext.
Q3.
What is the role of a cipher in encryption technology?

a.

It generates encryption keys.

b.

It transforms ciphertext into plaintext.

c.

It creates metadata for ciphertext.

d.

It transforms original plaintext data into encrypted data.

Discuss
Answer: (d).It transforms original plaintext data into encrypted data. Explanation:A cipher in encryption technology is used to transform original plaintext data into encrypted data (ciphertext).
Q4.
What is an encryption key?

a.

A secret message used to create ciphertext.

b.

A form of metadata for ciphertext.

c.

The original plaintext data.

d.

The transformed ciphertext.

Discuss
Answer: (a).A secret message used to create ciphertext. Explanation:An encryption key is a secret message used to create ciphertext from plaintext data.
Q5.
Which security threats can encryption help counter?

a.

Data corruption and system crashes.

b.

Physical theft of hardware.

c.

Unauthorized access to network resources.

d.

Inadequate user authentication.

Discuss
Answer: (c).Unauthorized access to network resources. Explanation:Encryption can help counter security threats like unauthorized access to network resources.
Q6.
How does encryption protect against traffic eavesdropping?

a.

By blocking network traffic.

b.

By using secret keys.

c.

By revealing plaintext.

d.

By transmitting metadata.

Discuss
Answer: (b).By using secret keys. Explanation:Encryption protects against traffic eavesdropping by using secret keys to encrypt and decrypt messages, making it difficult for unauthorized parties to access the original data.
Q7.
Which encryption type uses the same key for both encryption and decryption?

a.

Asymmetric encryption.

b.

Non-repudiation encryption.

c.

Symmetric encryption.

d.

Public key encryption.

Discuss
Answer: (c).Symmetric encryption. Explanation:Symmetric encryption uses the same key for both encryption and decryption.
Q8.
What is the key characteristic of symmetric encryption?

a.

It uses two different keys for encryption and decryption.

b.

It relies on public and private keys.

c.

Messages encrypted with a specific key can be decrypted by only that same key.

d.

It offers non-repudiation of messages.

Discuss
Answer: (c).Messages encrypted with a specific key can be decrypted by only that same key. Explanation:The key characteristic of symmetric encryption is that messages encrypted with a specific key can be decrypted by only that same key.
Q9.
Which type of encryption maintains data confidentiality but lacks non-repudiation?

a.

Symmetric encryption.

b.

Asymmetric encryption.

c.

Public key encryption.

d.

Non-repudiation encryption.

Discuss
Answer: (a).Symmetric encryption. Explanation:Symmetric encryption maintains data confidentiality but lacks non-repudiation.
Q10.
What is the primary difference between symmetric and asymmetric encryption?

a.

Symmetric encryption uses public and private keys.

b.

Asymmetric encryption uses the same key for encryption and decryption.

c.

Asymmetric encryption relies on two different keys.

d.

Symmetric encryption is computationally slower than asymmetric encryption.

Discuss
Answer: (c).Asymmetric encryption relies on two different keys. Explanation:The primary difference between symmetric and asymmetric encryption is that asymmetric encryption relies on two different keys (public and private keys) for encryption and decryption.
