CompTIA Cybersecurity Analyst (CySA+) Certification Exam Sample Questions (Q166-Q171):

NEW QUESTION # 166
An analyst executes the top command on a Linux system for an unresponsive application and observes the following output:

Which of the following is the most likely cause of this issue?

A. Unauthorized software
B. Resource exhaustion
C. Service disruption
D. Filesystem changes

Answer: B

Explanation:
Resource exhaustion is the most likely explanation because Linux top is specifically used to observe real- time system and process resource consumption. Its output provides system summary information and process- level metrics that allow an analyst to identify abnormal CPU or memory utilization, excessive process activity, load conditions, and other resource constraints. The Linux top manual describes the utility as providing a dynamic real-time view of the running system and its processes.
When an application becomes unresponsive while top indicates abnormally high processor consumption, memory pressure, or another exhausted resource, the immediate technical conclusion is resource exhaustion.
An application can become starved of CPU time, physical memory, or other capacity, causing severe degradation or apparent failure.
Service disruption is a description of an outcome rather than the underlying condition demonstrated by process-resource statistics. Unauthorized software would require evidence showing an unexpected or prohibited process rather than simply excessive utilization. Filesystem changes are normally investigated through filesystem auditing, integrity monitoring, timestamps, logs, or forensic comparison; top does not primarily report file modifications.
The examination distinction is therefore between symptom and cause : the unresponsive application is the symptom, while excessive resource consumption revealed by top identifies the probable root cause.

NEW QUESTION # 167
A security operations (SOC) manager develops response mechanisms as part of playbook development efforts. The SOC manager needs to accomplish the following:
- Document adversarial activities.
- Map adversarial activities to a linear progression of sequential phases.
- Provide broad coverage of threat actions without addressing specific
tactics, techniques, and procedures (TTPs).
Which of the following is the most reliable source for this information?

A. Cyber COBRA
B. MITRE ATT&CK
C. Diamond Model of Intrusion Analysis
D. Cyber Kill Chain

Answer: D

Explanation:
The Cyber Kill Chain documents adversarial activities as a linear sequence of phases, providing a high-level view of threat progression without focusing on detailed tactics, techniques, or procedures.

NEW QUESTION # 168
Which of the following best describes the main objective of the exploitation phase according to the Cyber Kill Chain methodology?

A. To actively scan for vulnerabilities
B. To send a malicious payload
C. To destroy logs
D. To gain access to a target

Answer: D

Explanation:
In the Cyber Kill Chain, the exploitation phase is where the attacker takes advantage of a vulnerability to execute malicious code and gain unauthorized access to the target system. This step follows delivery and represents the point at which the attack successfully compromises the target.

NEW QUESTION # 169
A security analyst needs to identify the devices in a critical infrastructure network that handles an oil and gas pipeline. The network has devices connected over IPv4 using either HTTP or Modbus protocols running on the standard ports. Which of the following approaches should the analyst use to achieve the objective?

A. Perform an nmap -T2 -A -p 80,502
B. Employ the IT vulnerability scanner to target ports 80 and 502
C. Use banner grabbing with netcat on TCP ports 80 and 502
D. Scan the ICS network using masscan --open-only -p80,502

Answer: C

Explanation:
Critical infrastructure and ICS environments require non-intrusive identification methods to avoid disrupting operational technology devices. Banner grabbing with netcat against the standard HTTP (80) and Modbus (502) ports allows the analyst to identify devices and services with minimal impact. More aggressive scanning techniques, service enumeration, and vulnerability scanning can adversely affect sensitive ICS systems and are generally avoided unless specifically approved and tested.

NEW QUESTION # 170
Which of the following is the most important component to include in the preparation phase of an incident response plan?

A. Chain of custody
B. Roles and responsibilities
C. Data integrity validation
D. After action reports

Answer: B

Explanation:
During preparation, the organization must clearly define who performs each incident response function so actions, escalation, and communication occur efficiently.
