What are the three components of the CIA triad in security?

• Integrity, Authentication, Availability

• Confidentiality, Authentication, Availability

• Confidentiality, Integrity, Authentication

• Confidentiality, Integrity, Availability

How does a hash function ensure data integrity?

• By generating a fixed-size hash value

• By compressing the data

• By encrypting the data

• By storing the data securely

What happens to the hash value if a small change is made to the input data?

• The hash value remains the same

• The hash value doubles in size

• The hash value changes slightly

• The hash value changes completely

Which hash algorithm is known for being the 'grandpa' of hashes?

• RIPEMD

• SHA-256

• MD5

• SHA-1

What is a collision in the context of hash functions?

• When a hash function is too slow

• When a hash value is too long

• When a hash function fails to produce a hash

• When two different inputs produce the same hash

Why are hashes used in password security?

• To verify password integrity

• To store passwords securely

• To encrypt passwords

• To prevent password reuse

In what context are hashes used alongside encryption?

• In data compression

• In network routing

• In encrypted web pages

• In data backup
