What is the primary purpose of TCP's sliding window mechanism?

To detect and correct bit errors in the payload

To encrypt data before transmission

To route packets through the most efficient path

To control the flow of data so the receiver is not overwhelmed

Which application is best suited for UDP rather than TCP?

Web browsing where pages must load completely

Live video streaming where occasional packet loss is acceptable

Email transmission where no data loss is acceptable

File transfer where data integrity is critical

What is a TCP socket?

The sequence number of the next byte to be sent

The buffer space allocated for incoming data

The physical network interface card used for transmission

The combination of source IP, source port, destination IP, and destination port

A network analyst sees a packet with the SYN flag set and the ACK flag set in the TCP header. What is the most likely context for this packet?

The second step of a three-way handshake, where the server acknowledges the client's SYN and sends its own SYN.

The first step of a connection initiation, where the client requests a connection.

A reset packet sent to abort an invalid connection.

The final step of connection termination, where the sender acknowledges a FIN.

TCP GCIA Practice Questions (Page 4)

Part of the Network Fundamentals domain, which makes up ~35% of our current practice bank. GIAC (SANS) does not publish an official question count, but from its 240-minute exam (~95–160 total, ~33–56 in this domain), expect 7–11 from this objective — we provide 50 practice questions to prepare you well beyond it.
