Q22

Which attack uses deceptive emails to steal information?

1. Phishing
   2. DDoS
   3. Port scanning
   4. Brute force

Correct Answer: 1. Phishing

Explanation:
Phishing is a social engineering attack that uses deceptive emails, messages, websites, or other communications to trick users into revealing sensitive information. Attackers may attempt to obtain passwords, financial information, or other credentials by pretending to be a trusted person or organization. DDoS attacks target availability, port scanning identifies network services, and brute-force attacks attempt many credential combinations. Therefore, phishing is the correct answer because it primarily relies on deception to persuade users to provide information or perform an unsafe action.

Q23

Which security measure protects data confidentiality?

1. Encryption
   2. Logging
   3. Routing
   4. Monitoring

Correct Answer: 1. Encryption

Explanation:
Encryption protects data confidentiality by converting readable information into an encoded form that unauthorized individuals cannot easily understand. Only users or systems with the appropriate decryption capability can access the original information. Encryption can protect data while it is stored or transmitted. Logging records activities, routing directs network traffic, and monitoring observes system behavior. While these controls are useful for security, they do not directly provide confidentiality in the same way encryption does. Therefore, encryption is the correct answer.

Q24

Which security concept ensures data is not improperly changed?

1. Integrity
   2. Availability
   3. Authentication
   4. Scalability

Correct Answer: 1. Integrity

Explanation:
Integrity ensures that data remains accurate, complete, and protected from unauthorized modification. Security controls such as hashing, digital signatures, access controls, and integrity monitoring can help detect or prevent unauthorized changes. Confidentiality protects information from unauthorized disclosure, while availability ensures systems and data remain accessible when needed. Authentication verifies identity, but it does not itself guarantee data integrity. Therefore, integrity is the correct answer because it focuses specifically on protecting information from unauthorized or improper modification.

Q25

Which security goal ensures systems remain accessible?

1. Availability
   2. Integrity
   3. Confidentiality
   4. Authentication

Correct Answer: 1. Availability

Explanation:
Availability means systems, applications, networks, and information remain accessible to authorized users when required. Organizations use redundancy, backups, monitoring, failover systems, and protection against denial-of-service attacks to improve availability. Confidentiality focuses on preventing unauthorized disclosure, while integrity protects information from unauthorized modification. Authentication verifies identity. Therefore, availability is the correct answer because it addresses whether resources remain operational and accessible when legitimate users need them.

Q26

Which device or system inspects and controls application traffic?

1. Next-generation firewall
   2. Printer
   3. Monitor
   4. Keyboard

Correct Answer: 1. Next-generation firewall

Explanation:
A next-generation firewall can inspect and control network traffic using information beyond basic IP addresses and ports. Palo Alto Networks next-generation firewalls can identify applications and users and apply security policies based on this context. They can also integrate security profiles to detect and prevent various threats. The other options are ordinary hardware devices and do not provide advanced network security inspection. Therefore, a next-generation firewall is the correct answer because it provides application-aware traffic inspection and policy enforcement.

Q27

What does a security policy define?

1. Allowed and blocked activity
   2. Screen brightness
   3. Printer speed
   4. Keyboard layout

Correct Answer: 1. Allowed and blocked activity

Explanation:
A security policy defines how security controls should handle different types of activity. In a firewall environment, policies can determine which users, applications, services, sources, and destinations are permitted or denied. Properly configured policies help organizations enforce security requirements and reduce unauthorized communication. Screen brightness, printer speed, and keyboard layout are unrelated to security policy enforcement. Therefore, allowed and blocked activity is the correct answer because security policies establish rules that determine what traffic or actions should be permitted or prevented.

Q28

Which technique detects unusual user behavior?

1. User behavior analytics
   2. File compression
   3. Data formatting
   4. Network routing

Correct Answer: 1. User behavior analytics

Explanation:
User behavior analytics examines user activity to identify unusual or potentially suspicious behavior. It can help detect activities such as unexpected access patterns, unusual login locations, abnormal data transfers, or behavior that differs significantly from a user’s normal baseline. This information can help security teams identify compromised accounts or insider threats. File compression, data formatting, and network routing do not analyze user behavior. Therefore, user behavior analytics is the correct answer because it focuses on identifying abnormal activity associated with users or accounts.

Q29

Which process identifies weaknesses in systems?

1. Vulnerability assessment
   2. Data backup
   3. File compression
   4. Account provisioning

Correct Answer: 1. Vulnerability assessment

Explanation:
A vulnerability assessment identifies weaknesses or security flaws in systems, applications, devices, and networks. Security teams can use scanning and analysis tools to identify outdated software, insecure configurations, missing patches, and other weaknesses that attackers could potentially exploit. Backups protect against data loss, compression reduces file size, and account provisioning creates or assigns user access. These activities do not primarily identify security weaknesses. Therefore, vulnerability assessment is the correct answer because its purpose is to discover and evaluate potential vulnerabilities.

Q30

Which action reduces risk from outdated software?

1. Applying security patches
   2. Sharing passwords
   3. Disabling monitoring
   4. Removing logs

Correct Answer: 1. Applying security patches

Explanation:
Applying security patches helps reduce the risk associated with vulnerabilities in operating systems, applications, and other software. Vendors release patches to fix known security weaknesses that attackers may otherwise exploit. Organizations should evaluate, test, and deploy important updates according to their patch-management processes. Sharing passwords, disabling monitoring, and removing logs can create additional security risks rather than reduce them. Therefore, applying security patches is the correct answer because keeping software updated helps close known vulnerabilities and strengthens the overall security posture.

Q31

Which method helps detect repeated failed login attempts?

1. Log monitoring
   2. File compression
   3. Data encryption
   4. Screen recording

Correct Answer: 1. Log monitoring

Explanation:
Log monitoring allows security teams to observe authentication events and identify patterns such as repeated failed login attempts. A large number of failures may indicate password guessing, brute-force activity, or another unauthorized access attempt. Monitoring logs can help analysts investigate the source, timing, and frequency of these events. Encryption protects information, compression reduces file size, and screen recording captures visual activity. Therefore, log monitoring is the correct answer because authentication logs provide useful evidence for identifying repeated login failures and suspicious access behavior.

Q32

Which solution helps detect threats across multiple security layers?

1. XDR
   2. DHCP
   3. NAT
   4. NTP

Correct Answer: 1. XDR

Explanation:
Extended Detection and Response (XDR) combines security data from multiple sources to improve threat detection, investigation, and response. Instead of examining each security layer separately, XDR can correlate relevant information from endpoints, networks, identities, cloud environments, and other sources. This provides analysts with broader context and can help identify complex attacks. DHCP, NAT, and NTP perform networking functions rather than extended threat detection. Therefore, XDR is the correct answer because it provides a broader, correlated approach to detecting and responding to security threats.

Q33

What is an indicator of compromise?

1. Evidence of possible malicious activity
   2. Normal system documentation
   3. Approved software
   4. Standard user training

Correct Answer: 1. Evidence of possible malicious activity

Explanation:
An Indicator of Compromise (IoC) is evidence that may suggest a system or environment has been compromised. Examples can include malicious IP addresses, suspicious domains, unusual files, unexpected processes, or known malware signatures. Security teams use IoCs during detection and investigation to identify potentially compromised systems and determine whether further analysis is necessary. Normal documentation, approved software, and standard training are not normally indicators of compromise. Therefore, evidence of possible malicious activity is the correct answer.

Q34

Which control helps protect against malicious URLs?

1. URL filtering
   2. DHCP
   3. NAT
   4. File compression

Correct Answer: 1. URL filtering

Explanation:
URL filtering helps organizations control access to websites and web resources based on security policies and categories. It can block known malicious, phishing, inappropriate, or otherwise unwanted URLs. This reduces the chance that users will accidentally access dangerous websites that could deliver malware or attempt to steal credentials. DHCP and NAT perform network functions, while file compression only reduces data size. Therefore, URL filtering is the correct answer because it directly helps prevent users from accessing potentially harmful web destinations.

Q35

Which technique can identify malicious behavior without relying only on signatures?

1. Behavioral analysis
   2. File naming
   3. Data sorting
   4. IP assignment

Correct Answer: 1. Behavioral analysis

Explanation:
Behavioral analysis identifies threats by examining how a file, process, application, or user behaves rather than relying only on known signatures. This can help detect previously unknown or modified threats that may not match existing signatures. For example, suspicious process execution, unauthorized system changes, or unusual communication patterns may indicate malicious behavior. File naming, data sorting, and IP assignment do not provide this type of security analysis. Therefore, behavioral analysis is the correct answer because it focuses on identifying suspicious actions and patterns.

Q36

Which process restores systems after a security incident?

1. Recovery
   2. Reconnaissance
   3. Scanning
   4. Authentication

Correct Answer: 1. Recovery

Explanation:
Recovery is the phase of incident response in which affected systems and services are restored to normal operation after an incident has been contained and addressed. Recovery may include restoring systems from backups, rebuilding compromised devices, validating security controls, and carefully returning services to production. Reconnaissance gathers information, scanning identifies systems or vulnerabilities, and authentication verifies identity. Therefore, recovery is the correct answer because its purpose is to restore affected systems and services while ensuring they can safely return to normal operation.

Q37

Which security practice helps preserve evidence during an investigation?

1. Log retention
   2. Log deletion
   3. Password sharing
   4. Unrestricted access

Correct Answer: 1. Log retention

Explanation:
Log retention helps preserve security records so investigators can review activity after an incident occurs. Logs may contain important information about authentication attempts, network connections, system changes, and other events. Keeping appropriate logs for a defined period allows security teams to investigate incidents and establish timelines. Deleting logs can remove valuable evidence, while password sharing and unrestricted access increase security risks. Therefore, log retention is the correct answer because maintaining security records supports incident investigation and forensic analysis.

Q38

Which security control isolates a compromised endpoint?

1. Endpoint isolation
   2. File compression
   3. Data sorting
   4. Screen sharing

Correct Answer: 1. Endpoint isolation

Explanation:
Endpoint isolation restricts a potentially compromised device from communicating with other systems while allowing security teams to investigate and remediate the threat. This can help prevent malware from spreading, limit attacker movement, and reduce the potential impact of a compromise. The isolated device may still maintain limited connectivity needed for security investigation or remediation. File compression, data sorting, and screen sharing do not provide this containment capability. Therefore, endpoint isolation is the correct answer because it directly helps contain a compromised endpoint.

Q39

Which attack attempts to guess passwords repeatedly?

1. Brute force
   2. Phishing
   3. DDoS
   4. Spoofing

Correct Answer: 1. Brute force

Explanation:
A brute-force attack attempts to gain unauthorized access by repeatedly trying different passwords or credential combinations until the correct one is discovered. Attackers may use automated tools to generate large numbers of attempts. Strong passwords, multifactor authentication, account lockout policies, rate limiting, and monitoring can help reduce the risk of successful brute-force attacks. Phishing relies on deception, DDoS targets availability, and spoofing involves impersonation. Therefore, brute force is the correct answer because it relies on repeated credential-guessing attempts.

Q40

Which capability helps prioritize security incidents?

1. Risk-based analysis
   2. File compression
   3. Screen resolution
   4. Data formatting

Correct Answer: 1. Risk-based analysis

Explanation:
Risk-based analysis helps security teams prioritize incidents according to factors such as potential impact, affected assets, threat severity, likelihood, and business importance. This allows analysts to focus resources on incidents that represent the greatest potential risk rather than treating every alert with the same priority. File compression, screen resolution, and data formatting do not help determine incident severity. Therefore, risk-based analysis is the correct answer because it provides a structured approach for evaluating and prioritizing security incidents.
