  • Q3
    What is the primary advantage of using symmetric encryption?
    It is faster than asymmetric encryption
    It is more secure than asymmetric encryption
    It requires a longer key length

  • Q4
    In symmetric encryption, what happens if the key is compromised?
    Only the sender is affected
    The encrypted data can be easily decrypted
    It becomes impossible to decrypt the data
    The data remains secure

  • Q5
    Which of the following statements best describes symmetric encryption?
    It automatically generates keys for each session
    It requires both parties to share a secret key before communication
    It can only encrypt small amounts of data
    It relies on a public key

  • Q6
    What is a common use case for symmetric encryption?
    Establishing secure web connections
    Encrypting files on a hard drive

  • Q7
    What is the main challenge of symmetric encryption?
    Securely sharing the encryption key
    Creating multiple keys for each user
    Finding the strongest encryption algorithm
    Encrypting data too slowly
    30s
  • Q8
    Which of the following describes the process of symmetric encryption?
    Data is split into multiple parts for encryption
    Data is sent in plain text
    Data is compressed to save space
    Data is transformed into an unreadable format using a secret key
    30s
  • Q9
    Which of the following is NOT an example of symmetric encryption?
    AES (Advanced Encryption Standard)
    DES (Data Encryption Standard)
    RSA
    Blowfish
    30s
  • Q10
    What typically happens to the performance of symmetric encryption as the key length increases?
    It eliminates the need for a key
    It becomes less secure
    It requires fewer resources
    It may take longer to encrypt and decrypt the data
