Question 61<\/b><\/h3>\n

Which security control helps identify unauthorized changes to files?<\/b><\/p>\n

    \n
  1. File integrity monitoring<\/span><\/li>\n
  2. Load balancer<\/span><\/li>\n
  3. VPN<\/span><\/li>\n
  4. DHCP<\/span><\/li>\n<\/ol>\n

    Correct Answer: 1<\/b><\/p>\n

    Explanation<\/b><\/p>\n

    File Integrity Monitoring, or FIM, detects changes to important files and system configurations. It can monitor file creation, modification, deletion, and other changes and alert security personnel when unexpected activity occurs. FIM is useful for identifying potential malware activity, unauthorized administrative actions, or attempts to modify critical system files. Security teams can establish baselines for important files and compare later activity against those expected states. Effective FIM requires careful configuration because monitoring too many low-value files can generate unnecessary alerts and increase investigation workload.<\/span><\/p>\n

    Question 62<\/b><\/h3>\n

    Which attack attempts to overwhelm a system by sending excessive traffic from many sources?<\/b><\/p>\n

      \n
    1. Man-in-the-middle<\/span><\/li>\n
    2. Distributed denial-of-service<\/span><\/li>\n
    3. SQL injection<\/span><\/li>\n
    4. Password spraying<\/span><\/li>\n<\/ol>\n

      Correct Answer: 2<\/b><\/p>\n

      Explanation<\/b><\/p>\n

      A Distributed Denial-of-Service, or DDoS, attack uses multiple systems or sources to generate large amounts of traffic or requests against a target. The goal is usually to consume available bandwidth, processing resources, connection capacity, or application resources so legitimate users cannot access the service normally. Analysts can examine traffic volume, source distribution, protocols, request patterns, and affected services when investigating a suspected DDoS event. Mitigation may involve filtering, rate limiting, traffic distribution, upstream protection, or specialized DDoS mitigation services.<\/span><\/p>\n

      Question 63<\/b><\/h3>\n

      What is the purpose of a security playbook?<\/b><\/p>\n

        \n
      1. Store passwords<\/span><\/li>\n
      2. Track hardware warranties<\/span><\/li>\n
      3. Define repeatable response procedures<\/span><\/li>\n
      4. Replace endpoint protection<\/span><\/li>\n<\/ol>\n

        Correct Answer: 3<\/b><\/p>\n

        Explanation<\/b><\/p>\n

        A security playbook documents repeatable procedures for responding to specific security events or operational situations. For example, an organization may have separate playbooks for phishing, ransomware, compromised credentials, or malware infections. Playbooks help analysts understand what actions should be performed, which teams should be contacted, and what evidence should be collected. They can improve consistency and reduce response delays during stressful incidents. Organizations should periodically test and update playbooks because technologies, threats, contact information, and internal procedures can change over time.<\/span><\/p>\n

        Question 64<\/b><\/h3>\n

        Which technology provides encrypted remote access to an organization’s network?<\/b><\/p>\n

          \n
        1. FTP<\/span><\/li>\n
        2. VPN<\/span><\/li>\n
        3. HTTP<\/span><\/li>\n
        4. SNMP<\/span><\/li>\n<\/ol>\n

          Correct Answer: 2<\/b><\/p>\n

          Explanation<\/b><\/p>\n

          A Virtual Private Network, or VPN, provides an encrypted communication channel between a user or device and a protected network or service. Organizations commonly use VPNs to provide secure remote access for employees and administrators. VPN security depends on strong authentication, secure protocols, appropriate access controls, and proper configuration. Analysts should monitor VPN authentication and connection logs for unusual locations, repeated failures, unexpected devices, or abnormal session behavior. A VPN protects communications but does not automatically make an authenticated user or device trustworthy.<\/span><\/p>\n

          Question 65<\/b><\/h3>\n

          Which process identifies systems and devices connected to an organization’s environment?<\/b><\/p>\n

            \n
          1. Asset discovery<\/span><\/li>\n
          2. Data encryption<\/span><\/li>\n
          3. Log rotation<\/span><\/li>\n
          4. Incident recovery<\/span><\/li>\n<\/ol>\n

            Correct Answer: 1<\/b><\/p>\n

            Explanation<\/b><\/p>\n

            Asset discovery identifies devices, systems, applications, services, and other technology resources within an organization’s environment. Maintaining an accurate asset inventory is important because security teams cannot effectively protect systems they do not know exist. Discovery can identify servers, workstations, network devices, cloud resources, and externally exposed assets. The inventory should be updated regularly because environments change as systems are deployed, removed, or modified. Asset discovery also supports vulnerability management because scanners and remediation processes need accurate information about the organization’s technology assets.<\/span><\/p>\n

            Question 66<\/b><\/h3>\n

            Which attack intercepts communication between two parties without their knowledge?<\/b><\/p>\n

              \n
            1. Brute force<\/span><\/li>\n
            2. Man-in-the-middle<\/span><\/li>\n
            3. Password spraying<\/span><\/li>\n
            4. Ransomware<\/span><\/li>\n<\/ol>\n

              Correct Answer: 2<\/b><\/p>\n

              Explanation<\/b><\/p>\n

              A Man-in-the-Middle, or MitM, attack occurs when an attacker positions themselves between communicating parties and intercepts or potentially modifies their communications. Depending on the attack, the attacker may attempt to steal credentials, manipulate transactions, or observe sensitive information. Strong encryption, certificate validation, secure network configurations, and appropriate authentication can reduce MitM risks. Analysts investigating suspected MitM activity should examine network traffic, certificate warnings, unexpected routing behavior, wireless activity, and authentication events to determine whether communications may have been intercepted or altered.<\/span><\/p>\n

              Question 67<\/b><\/h3>\n

              Which security process determines which vulnerabilities should be addressed first?<\/b><\/p>\n

                \n
              1. Vulnerability prioritization<\/span><\/li>\n
              2. Data destruction<\/span><\/li>\n
              3. Log aggregation<\/span><\/li>\n
              4. User provisioning<\/span><\/li>\n<\/ol>\n

                Correct Answer: 1<\/b><\/p>\n

                Explanation<\/b><\/p>\n

                Vulnerability prioritization determines which identified weaknesses should receive remediation attention first. Security teams can consider vulnerability severity, exploitability, asset criticality, exposure, business impact, known exploitation, and available compensating controls. This prevents organizations from treating every vulnerability as equally urgent when resources are limited. For example, a highly exploitable vulnerability affecting an internet-facing critical server may require faster action than a lower-risk issue on an isolated system. Effective prioritization connects technical vulnerability information with the organization’s actual risk context.<\/span><\/p>\n

                Question 68<\/b><\/h3>\n

                Which log source is most useful for investigating suspicious process execution on a Windows endpoint?<\/b><\/p>\n

                  \n
                1. Endpoint security logs<\/span><\/li>\n
                2. DNS zone records<\/span><\/li>\n
                3. Printer logs<\/span><\/li>\n
                4. HVAC logs<\/span><\/li>\n<\/ol>\n

                  Correct Answer: 1<\/b><\/p>\n

                  Explanation<\/b><\/p>\n

                  Endpoint security logs can provide detailed information about processes executed on a Windows system, including process names, parent processes, command-line information, timestamps, and other telemetry depending on the security product. Analysts can use this information to identify suspicious execution chains, unusual applications, scripting activity, or potential malware behavior. Process information becomes more useful when correlated with network connections, file activity, user accounts, and authentication events. This helps analysts determine whether an unusual process represents legitimate administrative activity or potential malicious execution.<\/span><\/p>\n

                  Question 69<\/b><\/h3>\n

                  Which cloud security principle requires permissions to be limited to necessary resources?<\/b><\/p>\n

                    \n
                  1. Open access<\/span><\/li>\n
                  2. Shared administration<\/span><\/li>\n
                  3. Least privilege<\/span><\/li>\n
                  4. Anonymous access<\/span><\/li>\n<\/ol>\n

                    Correct Answer: 3<\/b><\/p>\n

                    Explanation<\/b><\/p>\n

                    Least privilege limits users, applications, and services to the resources and actions necessary for their authorized responsibilities. In cloud environments, excessive permissions can create significant risk because compromised identities may provide attackers with access to many resources. Security teams should review identity roles, permissions, service accounts, and application access regularly. Temporary or task-specific access can also reduce unnecessary exposure. Cloud permissions should be designed carefully because a single overly broad role can potentially provide access to sensitive storage, databases, administrative functions, or other critical resources.<\/span><\/p>\n

                    Question 70<\/b><\/h3>\n

                    What is the main purpose of a vulnerability scanner?<\/b><\/p>\n

                      \n
                    1. Identify potential security weaknesses<\/span><\/li>\n
                    2. Recover deleted files<\/span><\/li>\n
                    3. Encrypt network traffic<\/span><\/li>\n
                    4. Manage user salaries<\/span><\/li>\n<\/ol>\n

                      Correct Answer: 1<\/b><\/p>\n

                      Explanation<\/b><\/p>\n

                      A vulnerability scanner automatically examines systems, applications, and network services for known vulnerabilities, insecure configurations, missing patches, and other weaknesses. Scan results typically include information about discovered assets, identified vulnerabilities, severity, and remediation recommendations. Security teams use these results as part of vulnerability management and risk prioritization. Scanners do not always prove that a vulnerability can be exploited successfully, so findings may require validation or penetration testing. Regular scanning helps maintain visibility as new systems, software versions, and vulnerabilities are introduced.<\/span><\/p>\n

                      Question 71<\/b><\/h3>\n

                      Which attack uses malicious software to encrypt files and demand payment?<\/b><\/p>\n

                        \n
                      1. Ransomware<\/span><\/li>\n
                      2. Spyware<\/span><\/li>\n
                      3. Adware<\/span><\/li>\n
                      4. Rootkit<\/span><\/li>\n<\/ol>\n

                        Correct Answer: 1<\/b><\/p>\n

                        Explanation<\/b><\/p>\n

                        Ransomware is malware that commonly encrypts files or otherwise prevents access to data and then demands payment from victims. Modern ransomware attacks may also involve data theft before encryption, creating additional pressure on organizations. Security teams can reduce ransomware risk through reliable backups, endpoint protection, patch management, network segmentation, least privilege, application controls, and effective monitoring. During an incident, analysts should isolate affected systems, preserve evidence, identify the scope of the compromise, and follow the organization’s incident-response procedures rather than assuming that paying a demand will resolve the underlying security issue.<\/span><\/p>\n

                        Question 72<\/b><\/h3>\n

                        Which method can help identify malicious activity by comparing current behavior with a normal baseline?<\/b><\/p>\n

                          \n
                        1. Behavioral analysis<\/span><\/li>\n
                        2. File compression<\/span><\/li>\n
                        3. Data deletion<\/span><\/li>\n
                        4. Port forwarding<\/span><\/li>\n<\/ol>\n

                          Correct Answer: 1<\/b><\/p>\n

                          Explanation<\/b><\/p>\n

                          Behavioral analysis compares observed activity with expected or previously established patterns to identify anomalies that may indicate malicious behavior. Analysts can examine factors such as login times, process execution, network connections, data transfers, or resource usage. Unlike signature-based detection, behavioral analysis can potentially identify previously unknown threats when their activity differs significantly from normal behavior. However, legitimate changes can also appear anomalous, so analysts should investigate alerts using additional context. Baselines should be updated as normal business activity and system configurations change.<\/span><\/p>\n

                          Question 73<\/b><\/h3>\n

                          Which control helps prevent unauthorized execution of applications?<\/b><\/p>\n

                            \n
                          1. Application allowlisting<\/span><\/li>\n
                          2. DNS caching<\/span><\/li>\n
                          3. Network address translation<\/span><\/li>\n
                          4. Load balancing<\/span><\/li>\n<\/ol>\n

                            Correct Answer: 1<\/b><\/p>\n

                            Explanation<\/b><\/p>\n

                            Application allowlisting permits only approved applications or software to execute on a system. This can reduce the risk of unauthorized or malicious programs running on protected endpoints. Depending on the implementation, allowlisting may use application names, publishers, hashes, paths, or other attributes to determine whether execution is permitted. It is particularly useful on systems with predictable workloads. Security teams must maintain the approved application list because legitimate software updates or business requirements can otherwise be blocked. Properly configured allowlisting can provide a strong preventive endpoint control.<\/span><\/p>\n

                            Question 74<\/b><\/h3>\n

                            What is the primary goal of digital forensics during an incident?<\/b><\/p>\n

                              \n
                            1. Increase bandwidth<\/span><\/li>\n
                            2. Collect and analyze evidence<\/span><\/li>\n
                            3. Replace security policies<\/span><\/li>\n
                            4. Improve printer performance<\/span><\/li>\n<\/ol>\n

                              Correct Answer: 2<\/b><\/p>\n

                              Explanation<\/b><\/p>\n

                              Digital forensics involves collecting, preserving, and analyzing digital evidence to understand security incidents and other events. Analysts may examine disk contents, memory, logs, network captures, browser artifacts, authentication records, and other sources. The goal is to determine what happened, how the incident occurred, what systems were affected, and what actions the attacker performed. Evidence should be collected using appropriate procedures to preserve integrity and support reliable conclusions. Forensic findings can help guide containment, eradication, recovery, and future security improvements.<\/span><\/p>\n

                              Question 75<\/b><\/h3>\n

                              Which control can detect sensitive data being sent through email?<\/b><\/p>\n

                                \n
                              1. DLP<\/span><\/li>\n
                              2. DHCP<\/span><\/li>\n
                              3. NTP<\/span><\/li>\n
                              4. NAT<\/span><\/li>\n<\/ol>\n

                                Correct Answer: 1<\/b><\/p>\n

                                Explanation<\/b><\/p>\n

                                Data Loss Prevention systems can inspect email and other communication channels for sensitive information that may be leaving an organization’s controlled environment. DLP policies can identify information based on content patterns, classifications, labels, or other rules. Depending on organizational configuration, the system may alert analysts, block a message, quarantine content, or require additional approval. DLP policies should be carefully tuned to reduce false positives and avoid disrupting legitimate communication. Organizations should also define appropriate procedures for handling DLP alerts and approved exceptions.<\/span><\/p>\n

                                Question 76<\/b><\/h3>\n

                                Which concept describes using multiple layers of security controls?<\/b><\/p>\n

                                  \n
                                1. Defense in depth<\/span><\/li>\n
                                2. Single sign-on<\/span><\/li>\n
                                3. Data minimization<\/span><\/li>\n
                                4. Network address translation<\/span><\/li>\n<\/ol>\n

                                  Correct Answer: 1<\/b><\/p>\n

                                  Explanation<\/b><\/p>\n

                                  Defense in depth uses multiple layers of security controls so that the failure or bypass of one control does not automatically result in complete compromise. Layers can include identity controls, endpoint protection, firewalls, network segmentation, encryption, monitoring, vulnerability management, and security awareness. This approach recognizes that no individual security control is perfect. For example, even if an attacker bypasses an email filter, endpoint protection and network monitoring may still detect their activity. Defense in depth therefore helps reduce dependence on a single protective mechanism.<\/span><\/p>\n

                                  Question 77<\/b><\/h3>\n

                                  Which activity examines publicly available information about an organization?<\/b><\/p>\n

                                    \n
                                  1. OSINT gathering<\/span><\/li>\n
                                  2. Disk imaging<\/span><\/li>\n
                                  3. Memory dumping<\/span><\/li>\n
                                  4. Log rotation<\/span><\/li>\n<\/ol>\n

                                    Correct Answer: 1<\/b><\/p>\n

                                    Explanation<\/b><\/p>\n

                                    Open-Source Intelligence, or OSINT, involves collecting and analyzing information from publicly available sources. Security professionals can use OSINT during authorized assessments to identify exposed domains, technologies, employee information, leaked credentials, public documents, and other information that could contribute to an organization’s attack surface. Attackers may also use publicly available information during reconnaissance. Organizations should therefore monitor and manage information that unintentionally exposes sensitive details. Analysts should verify the reliability of OSINT because public information can be outdated, inaccurate, or intentionally misleading.<\/span><\/p>\n

                                    Question 78<\/b><\/h3>\n

                                    Which response action limits a compromised endpoint’s communication with other systems?<\/b><\/p>\n

                                      \n
                                    1. Data classification<\/span><\/li>\n
                                    2. Network isolation<\/span><\/li>\n
                                    3. Password expiration<\/span><\/li>\n
                                    4. Asset tagging<\/span><\/li>\n<\/ol>\n

                                      Correct Answer: 2<\/b><\/p>\n

                                      Explanation<\/b><\/p>\n

                                      Network isolation separates a compromised endpoint from other systems or restricts its network communication to prevent further spread or unauthorized activity. It is a common containment action during malware or account-compromise investigations. Isolation should be performed carefully because completely disconnecting a system may affect forensic evidence or prevent analysts from collecting useful information. Organizations should follow established incident-response procedures and determine which communication must remain available for investigation. The purpose is to limit attacker movement and reduce additional damage while the security team investigates the compromise.<\/span><\/p>\n

                                        Correct Answer: 3<\/b><\/p>\n

                                        Explanation<\/b><\/p>\n

                                        Mean Time to Respond, commonly represented as MTTR in security contexts, measures the average time required to respond to detected security incidents. Depending on the organization’s definitions, related metrics may measure containment, recovery, or resolution separately, so teams should clearly document what their MTTR calculation includes. Tracking response time helps organizations identify operational delays and evaluate improvements to incident-response processes. Factors affecting response time can include alert quality, analyst availability, automation, escalation procedures, incident complexity, and the accessibility of required evidence.<\/span><\/p>\n

                                          Correct Answer: 1<\/b><\/p>\n

                                          Explanation<\/b><\/p>\n

                                          Persistence hunting involves searching systems for mechanisms that allow an attacker or malicious software to remain active after reboots, logoffs, or other interruptions. Analysts may examine scheduled tasks, startup locations, services, registry entries, user accounts, scripts, applications, and other persistence points. Finding persistence is important because simply removing visible malware may not fully eliminate an attacker from a compromised system. Security teams should investigate suspicious persistence mechanisms, determine when they were created, identify their associated processes or accounts, and remove them as part of eradication.<\/span><\/p>\n
