TOPIC 1: VULNERABILITIES AND ATTACKS
10 Questions • 10.1% of Exam • This topic covers various vulnerabilities and attack methodologies affecting systems and networks.
QUESTION 1
Which of the following vulnerabilities is exploited when an attacker overwrites a
register with amalicious address?
A. VM escape
B. SQL injection
C. Buffer overflow
D. Race condition
Answer: C. Buffer overflow.
Rationale: Overwriting a register with a malicious address exploits a buffer overflow, a vulnerability where program
execution is diverted by writing data beyond the allocated buffer's boundaries. This principle of exceeding allocated memory
space is central to buffer overflow attacks.
QUESTION 2
Which of the following is a primary security concern for a company setting up a
BYODprogram?
A. End of life
B. Buffer overflow
C. VM escape
D. Jailbreaking
Answer: D. Jailbreaking.
Rationale: Jailbreaking circumvents the built-in security controls of a mobile device, allowing unauthorized access and
modification of the operating system, which is a primary concern when personal devices are used for corporate data. This
bypass of security measures poses a significant risk to data integrity and confidentiality within a BYOD program.

QUESTION 3
Which of the following describes the process of concealing code or text inside a
graphicalimage?
A. Symmetric encryption
B. Hashing
C. Data masking
D. Steganography
Answer: D. Steganography.
Rationale: Steganography is the practice of hiding secret data within an ordinary, non-secret file or message, such as an
image, to avoid
detection. This differs from encryption, which scrambles data, and hashing, which creates a fixed-size digest for integrity
checks.
QUESTION 4
An organization's internet-facing website was compromised when an attacker exploited
a buffer overflow. Which of the following should the organization deploy to best protect
against similar attacks in the future?
A. NGFW
B. WAF
C. TLS
D. SD-WAN
Answer: B. WAF.
Rationale: A Web Application Firewall (WAF) inspects and filters HTTP traffic to and from a web application, specifically
designed to detect and block common web attacks like buffer overflows. This directly addresses the vulnerability exploited in
the compromise by providing application-layer security.
