Practice questions
Q1An IP packet has arrived with the first 8 bits as .01000010. Which of the following is correct?
In an IPv4 header, the first 4 bits give the version and the next 4 bits give the Internet Header Length. The bits 01000010 mean version 4 and IHL 2, but RFC 791 states that the minimum correct IPv4 header length value is 5. Since IHL 2 is invalid, the receiver rejects the packet; option D is correct.
Q2Hacktivism is -
Hacktivism means hacking carried out for political or social objectives. Option D states that motive directly. A describes leaking information generally, B resembles ethical hacking, and C resembles security testing.
Q3In FTP, there are three types of ................, stream, block and compressed.
In FTP, stream, block, and compressed are the three transmission modes. They describe how file data is sent over the data connection. They are not file types or data types, so option C is correct.
Q4The information that gets transformed in encryption is -
NIST defines encryption as the process of transforming plaintext into ciphertext using a cryptographic algorithm and key. The information that is transformed at the start is therefore plaintext. Hence option A is correct.
Q5What are the forms of password cracking techniques?
Option D is correct because password cracking can use syllable attacks, brute-force attacks, and hybrid attacks. A syllable attack tries likely word parts, brute force tries combinations systematically, and a hybrid attack combines dictionary-style guesses with rules or variations. Thus all three listed forms are valid password-cracking techniques.
