Question #61
Robust background checks provide protection against:
- A . distributed dental of service (DDoS) attacks.
- B . insider threats.
- C . phishing.
- D . ransomware.
Correct Answer: B
B
Explanation:
Robust background checks help mitigate insider threats by ensuring that individuals with access to sensitive data or critical systems do not have a history of risky or malicious behavior.
Screening: Identifies red flags like past criminal activity or suspicious financial behavior.
Trustworthiness Assessment: Ensures that employees handling sensitive information have a proven history of integrity.
Insider Threat Mitigation: Helps reduce the risk of data theft, sabotage, or unauthorized access.
Periodic Rechecks: Maintain ongoing security by regularly updating background checks.

Question #62
Which of the following Is a control message associated with the Internet Control Message Protocol (ICMP)?
- A . Transport Layer Security (TLS) protocol version Is unsupported.
- B . Destination is unreachable.
- C . 404 is not found.
- D . Webserver Is available.
Correct Answer: B
B
Explanation:
The Internet Control Message Protocol (ICMP) is used for error reporting and diagnostics in IP networks.
Control Messages: ICMP messages inform the sender about network issues, such as:
Destination Unreachable: Indicates that the packet could not reach the intended destination.
Echo Request/Reply: Used in ping to test connectivity.
Time Exceeded: Indicates that a packet’s TTL (Time to Live) has expired.
Common Usage: Troubleshooting network issues (e.g., ping and traceroute).

The enterprise has been receiving a large amount of false positive alerts for the eternalblue vulnerability. The SIEM rulesets are located in
/home/administrator/hids/ruleset/rules.
What is the name of the file containing the ruleset for eternalblue connections? Your response must include the file extension.
Correct Answer: Step 1: Define the Problem and Objective
Objective:
Identify the file containing the ruleset for EternalBlue connections.
Include the file extension in the response.
Context:
The organization is experiencing false positive alerts for the EternalBlue vulnerability.
The rulesets are located at:
/home/administrator/hids/ruleset/rules
We need to find the specific file associated with EternalBlue.
Step 2: Prepare for Access

Question #64
Which of the following would BCST enable an organization to prioritize remediation activities when multiple vulnerabilities are identified?
- A . Business Impact analysis (BIA)
- B . Vulnerability exception process
- C . executive reporting process
- D . Risk assessment
Correct Answer: D
D
Explanation:
A risk assessment enables organizations to prioritize remediation activities when multiple vulnerabilities are identified because:
Contextual Risk Evaluation: Assesses the potential impact and likelihood of each vulnerability.
Prioritization: Helps determine which vulnerabilities pose the highest risk to critical assets.
Resource Allocation: Ensures that remediation efforts focus on the most significant threats.
Data-Driven Decisions: Uses quantitative or qualitative metrics to support prioritization.

Question #65
A cybersecurity analyst has discovered a vulnerability in an organization’s web application.
Which of the following should be done FIRST to address this vulnerability?
- A . Restart the web server hosting the web application.
- B . Immediately shut down the web application to prevent exploitation.
- C . Follow the organization’s incident response management procedures.
- D . Attempt to exploit the vulnerability to determine its severity.
Correct Answer: C
C
Explanation:
When a cybersecurity analyst discovers a vulnerability, the first step is to follow the organization’s incident response procedures.
Consistency: Ensures that the vulnerability is handled systematically and consistently.
Risk Mitigation: Prevents hasty actions that could disrupt services or result in data loss.
Documentation: Helps record the discovery, assessment, and remediation steps for future reference.
Coordination: Involves relevant stakeholders, including IT, security teams, and management.

Question #66
Which of the following is the core component of an operating system that manages resources, implements security policies, and provides the interface between hardware and software?
- A . Kernel
- B . Library
- C . Application
- D . Shell
Correct Answer: A
A
Explanation:
The kernel is the core component of an operating system (OS) responsible for:
Resource Management: Manages CPU, memory, I/O devices, and other hardware resources.
Security Policies: Enforces access control, user permissions, and process isolation.
Hardware Abstraction: Acts as an intermediary between the hardware and software, providing low-level device drivers.
Process and Memory Management: Handles process scheduling, memory allocation, and inter-process communication.
Incorrect Options:
B. Library: A collection of functions or routines that can be used by applications, not the core of the OS.
C. Application: Runs on top of the OS, not a part of its core functionality.
D. Shell: An interface for users to interact with the OS, but not responsible for resource management.
Exact Extract from CCOA Official Review Manual, 1st Edition:
Refer to Chapter 4, Section "Operating System Security," Subsection "Kernel Responsibilities" – The kernel is fundamental to managing system resources and enforcing security.

Question #67
Which of the following is the PRIMARY security related reason to use a tree network topology rather than a bus network topology?
- A . It enables easier network expansion and scalability.
- B . It enables better network performance and bandwidth utilization.
- C . It is more resilient and stable to network failures.
- D . It Is less susceptible to data Interception and eavesdropping.
Correct Answer: C
C
Explanation:
A tree network topology provides better resilience and stability compared to a bus topology:
Fault Isolation: In a tree topology, a failure in one branch does not necessarily bring down the entire network.
Hierarchy Structure: If a single link fails, only a segment of the network is affected, not the whole system.
Easier Troubleshooting: The hierarchical layout allows for easier identification and isolation of faulty nodes.
Compared to Bus Topology: In a bus topology, a single cable failure can disrupt the entire network.
