Questions 1 – 114
DATABASES, NET WORKS & SECURITY
1. SQL injection occurs when a hacker issues a SQL command to a web server as part of a
URL. This attack works because:
A. the web server is expecting SQL commands in URLs
B. the web server is not expecting a SQL command and may pass it to the database, where
malicious code can execute
C. all SQL commands are inherently malicious
D. the database automatically blocks unknown commands
CORRECT ANSWER B
RATIONALE SQL injection exploits insufficient input validation — the web server passes
unexpected SQL commands to the database, which then executes them,
potentially damaging or exposing data.
2. The correct order of computer generations is:
A. Transistors → Vacuum Tubes → Integrated Circuits → Microprocessors
B. Vacuum Tubes → Transistors → Integrated Circuits → Microprocessors
C. Microprocessors → Integrated Circuits → Transistors → Vacuum Tubes
D. Integrated Circuits → Vacuum Tubes → Transistors → Microprocessors
CORRECT ANSWER B
RATIONALE Computer generations: 1st = Vacuum Tubes, 2nd = Transistors, 3rd = Integrated
Circuits, 4th = Microprocessors. Emerging 5th generation includes AI, quantum
computing, and nanotechnology.
,3. A relational database is distinguished by:
A. one large single table without relations
B. multiple tables with interrelated fields that can be queried across relations
C. a tree-like parent-child structure
D. storage of only text data
CORRECT ANSWER B
RATIONALE Relational databases organize data into multiple related tables. Queries can pull
data from any number of relations across multiple databases, providing great
flexibility. Flat files (A) use one table.
4. A JOIN operation in a database:
A. combines two tables, but records are only appended when a matching criterion is met
B. combines all records regardless of matching criteria
C. deletes duplicate records from a single table
D. creates a backup of the database
CORRECT ANSWER A
RATIONALE JOIN combines records from two tables based on a matching criterion (e.g.,
matching primary and foreign keys). UNION (B) combines distinct fields without
requiring matches.
, 5. Social engineering targets users directly and could include:
A. only hardware-based attacks
B. calling and asking for passwords because there is an issue, or phishing emails redirecting
to malicious websites
C. only SQL injection attacks
D. only buffer overflow exploits
CORRECT ANSWER B
RATIONALE Social engineering exploits human psychology rather than technical
vulnerabilities — phishing, pretexting, baiting, and impersonation attacks trick
users into revealing sensitive information.
6. A virtual machine allows access to multiple machines without purchasing multiple
computers and also:
A. requires a separate physical computer for each operating system
B. allows users to run software for a computer that normally would not be able to run that
software
C. replaces the need for any hardware
D. only works on Linux systems
CORRECT ANSWER B
RATIONALE VMs emulate entire computer systems, allowing users to run different operating
systems and software on a single physical machine without additional hardware
purchases.
