NEW QUESTION # 26
Given the following report:
Which of the following vulnerabilities should be prioritized for immediate remediation?
Answer: D
Explanation:
The SQL injection vulnerability should be remediated first because it affects a critical financial processing module, is exploitable over the network, requires no privileges, requires no user interaction, and has a known exploit available. Although the remote code execution vulnerability has a slightly higher CVSS score, it requires privileges and user interaction and does not have a known exploit available. Considering exploitability, business context, and asset criticality, the SQL injection vulnerability presents the highest immediate risk.
NEW QUESTION # 27
A security operations center (SOC) analyst investigates the results of a password spray test conducted by the vulnerability management team.
The analyst must:
Identify Linux systems that have successful and unsuccessful logins with username "User1".
Create an output report named "linux-events" of all the events to a flat file.
The analyst issues the following console command:
ls /var/log/
The shortened output of the command is below:
Which of the following commands should the analyst use to meet the report output requirements?
Answer: A
Explanation:
/var/log/auth.log is the appropriate source because it records authentication and authorization activity on Debian/Ubuntu-style Linux systems, including password-related events, SSH logins, PAM authentication, and other authorization events. Canonical's Ubuntu documentation specifically identifies /var/log/auth.log as the authorization log used for password prompts, sudo, and remote logins.
The command performs three operations. cat /var/log/auth.log sends the log contents to standard output. The pipe forwards that data to grep "User1", which selects records containing the required username. Finally, > linux-events.txt redirects the resulting matching records into the requested flat-file report. Because auth.log can contain both accepted and rejected authentication activity, the command can capture successful and unsuccessful events associated with User1.
sssd is not the general authentication log path shown in the scenario and may contain only SSSD-specific events. A faillog-oriented source emphasizes failed logins and therefore does not satisfy the requirement to collect both successful and failed activity. /var/log/syslog contains broad system messages but is less precise than the dedicated authentication log.

NEW QUESTION # 28
A security analyst performs a vulnerability scan on the corporate assets and finds the following vulnerabilities:
The vulnerability manager reviews the analyst's recommendations and asks the analyst to add more information in order to confirm prioritization. Which of the following best explains the reason the manager requests more information?
Answer: C
Explanation:
CVSS scores alone are not sufficient to prioritize remediation efforts. The criticality of the affected host or asset must also be considered. A vulnerability with a lower CVSS score on a mission- critical system may present a greater business risk than a higher-scoring vulnerability on a less important system. The manager is requesting additional information to perform proper risk-based prioritization.
NEW QUESTION # 29
The Chief Information Security Officer wants to improve internal security measures by continuously validating and verifying access to the production environment.
Which of the following concepts best describes this practice?
Answer: C
Explanation:
Zero Trust is based on the principle that access should not be implicitly trusted merely because a user, workload, or device has already entered the enterprise environment. Access decisions are continuously evaluated using identity, authentication state, device posture, authorization, contextual information, and resource sensitivity. The scenario's emphasis on continuously validating and verifying access therefore directly describes Zero Trust.
Traditional perimeter-oriented models tend to treat internal network position as a degree of trust. Zero Trust removes that assumption and requires explicit verification before granting access to protected resources. It also supports least privilege, granular authorization, segmentation, and ongoing assessment of sessions or identities.
Secure access service edge combines networking and security capabilities delivered through a distributed service architecture and can support Zero Trust implementations, but SASE itself is not the fundamental principle described. A next-generation firewall provides application-aware traffic inspection and policy enforcement but does not by itself establish continuous identity-centric verification. Privileged access management specifically controls elevated or administrative accounts; it is an important component of access security but addresses a narrower scope than Zero Trust.
The CS0-004 objectives explicitly identify Zero Trust Network Architecture , SASE, hybrid cloud, IAM, PAM, authentication, and authorization as Security Operations architecture concepts.
Study Guide Reference: Security Operations # Network Architecture # Zero Trust Network Architecture # IAM # Authentication and Authorization # Least Privilege.
NEW QUESTION # 30
An analyst receives the following output:
Which of the following is the correct number of discovered systems that are allowing unencrypted traffic?
Answer: D
Explanation:
The scan results identify two systems exposing services that permit communications without transport encryption, making B the correct count. The analyst must examine each discovered service rather than merely count open ports, because the security property being evaluated is whether the identified protocol transmits its session or application data without adequate encryption.
Common examples include HTTP instead of HTTPS, Telnet instead of SSH, and legacy FTP rather than protected file-transfer alternatives. The presence of an unencrypted service does not automatically prove that sensitive information is currently being transmitted, but it identifies a configuration that can expose credentials, commands, session content, or application data to interception when used.
The correct vulnerability-management workflow is to map discovered ports to services, determine the security characteristics of those protocols, verify whether encryption is available and enforced, and then prioritize remediation according to asset exposure and business requirements. Where possible, administrators should disable unnecessary cleartext services or replace them with cryptographically protected equivalents.
This question therefore tests interpretation of vulnerability or port-scan output , not simple arithmetic.
The two affected systems are those whose discovered services permit cleartext communications.
