**Question 1.** Which layer of the OSI model is responsible for end-to-end reliability and flow control?
A) Physical
B) Data Link
C) Network
D) Transport
Answer: D
Explanation: The Transport layer (Layer 4) provides reliability, sequencing, and flow control (e.g., TCP).
**Question 2.** In a Zero Trust Architecture, which principle is most critical?
A) Perimeter firewalls block all traffic.
B) Trust any device inside the corporate network.
C) Verify every access request regardless of origin.
D) Use static passwords for all users.
Answer: C
Explanation: Zero Trust assumes no implicit trust; every request must be authenticated and authorized.
**Question 3.** Which of the following is a stateful firewall feature?
A) Packet filtering based only on IP header.
B) Maintaining connection tables to track sessions.
C) Blocking all inbound traffic.
D) Performing DNS resolution.
Answer: B
Explanation: Stateful firewalls keep track of active connections, allowing return traffic for established
sessions.

**Question 5.** Which NoSQL database type stores data as key-value pairs?
A) Document store
B) Column-family store
C) Graph database
D) Key-value store
Answer: D
Explanation: Key-value stores (e.g., Redis) map a unique key to a value, ideal for simple lookups.
**Question 6.** In relational databases, which index type improves range queries?
A) Hash index
B) B-tree index
C) Full-text index
D) Bitmap index
Answer: B
Explanation: B-tree indexes preserve order, making them efficient for range scans.
**Question 7.** The ETL step that transforms data from source format to target schema is called:
A) Extract
B) Load
C) Transform
D) Validate
