NEW QUESTION # 32
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: D
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 # 33
A security analyst receives a notice about a possible data breach. The report identifies unapproved, current access dates for files found in the following personnel archives:
Which of the following actions should the analyst take first?
Answer: E
Explanation:
The analyst should first establish a legal hold because the suspected breach involves personnel records and evidence that may become relevant to regulatory, disciplinary, civil, or other legal proceedings. A legal hold prevents potentially relevant information from being deleted, overwritten, modified, rotated out under normal retention schedules, or otherwise destroyed before the organization's legal and investigative obligations are understood.
Preservation must precede destructive or potentially evidence-altering actions. NIST describes digital forensics as retrieving, storing, and analyzing electronic information while ensuring that evidence is captured reliably without alteration. RFC 3227 similarly emphasizes preserving evidence, following proper collection procedures, documenting handling, and maintaining chain of custody.
Log correlation and timeline construction are important investigative activities, but they should occur after preservation requirements have been established. Resetting credentials may subsequently be required for containment, but the scenario first raises an evidence-preservation obligation. Restoring files from backup would be especially premature because it could alter timestamps, overwrite artifacts, or otherwise complicate forensic analysis.
The examination principle is therefore preserve first when legal implications are reasonably foreseeable; analyze and remediate afterward under controlled procedures .

NEW QUESTION # 34
A security operations center analyst is using the command line to display specific traffic.
The analyst uses the following command:
$tshark -r file.pcap -Y "http or udp"
Which of the following will the command line display?
Answer: A
Explanation:
The -r file.pcap argument instructs TShark to read packets from the specified capture file, while -Y applies a Wireshark display filter . The expression "http or udp" therefore displays packets recognized as HTTP or packets using UDP.
Traditional HTTP traffic is unencrypted and can be dissected directly as HTTP. HTTPS normally carries HTTP inside TLS encryption and therefore is not displayed merely because the filter specifies http. DNS commonly operates over UDP, particularly for standard queries and responses, so ordinary DNS traffic satisfies the udp portion of the expression. Consequently, B is the best answer in the context of the available choices.
A technical distinction is important: the expression does not mean "HTTP or DNS specifically." The udp portion matches UDP traffic generally, which can include protocols other than DNS. Nevertheless, within the examination scenario, the intended comparison is plaintext HTTP versus encrypted HTTPS together with standard UDP-based DNS.
Wireshark's documentation distinguishes display filters from capture filters, and TShark is the command-line network traffic analyzer within the Wireshark suite. CS0-004 places packet-analysis capabilities within Security Operations.

NEW QUESTION # 35
Which of the following is a reason the false-positive rate is an important metric for incident response reporting and communication?
Answer: D
Explanation:
A high false-positive rate leads to unnecessary investigation of benign alerts, consuming analyst time and resources, which reduces overall efficiency and can delay response to actual threats.
NEW QUESTION # 36
A security analyst analyzes the output of a web application access log for a company based in the United States. Given the following output:
Which of the following users should be investigated first?
Answer: A
Explanation:
tlindy has a successful login from a Russian IP address between successful U.S.-based logins, indicating a potentially compromised account or impossible-travel activity. The other Russian login attempts shown were unsuccessful.
