NEW QUESTION # 10
Which database has multiple tables with interrelated fields?
- A. Flat file
- B. Relational
- C. Hierarchical
- D. Interrelated
Answer: B
Explanation:
* Arelational databaseis structured to recognize relations among stored items of information.
* Multiple tablesin a relational database can have interrelated fields.
* These relationships are often managed throughforeign keys, which reference the primary keys of other tables.
* This relational model allows for complex queries and data integrity across the database.

NEW QUESTION # 11
Which type of systems testing includes having end users test the system with simulated data and the help of the developer?
- A. User Acceptance
- B. Analysis
- C. Alpha
- D. Beta
Answer: C
Explanation:
Alpha testing is a type of system testing that involves having end users test the system with simulated data and the help of the developer. This phase is crucial because:
* Early feedback: Users provide early feedback on the usability and functionality of the system.
* Bug identification: Developers can identify and fix bugs before the system is released for beta testing or production.
* Simulated environment: The testing is done in a controlled, simulated environment, often within the development organization.
Alpha testing is followed by beta testing, where the system is tested in a real-world environment by end users without the developers' direct involvement.

NEW QUESTION # 12
Which technique allows someone to obtain a password while it is in transit?
- A. Phishing
- B. Buffer overflow
- C. Black hat
- D. Packet sniffing
Answer: D
Explanation:
* Packet sniffing is a technique used to capture and analyze network traffic, which can include intercepting passwords while they are in transit.
* When data packets are transmitted over a network, a packet sniffer can capture these packets, and if they are not encrypted, it can read sensitive information like passwords.
* The other options:
* Buffer overflow is a type of attack that exploits a program's memory handling.
* Phishing is a social engineering attack to deceive users into providing sensitive information.
* Black hat refers to a hacker with malicious intent, not a specific technique.
* Therefore, packet sniffing is the correct technique for obtaining passwords in transit.
