CompTIA Cybersecurity Analyst (CySA+) Certification Exam Sample Questions (Q87-Q92):

NEW QUESTION # 87
An organization is planning to adopt a zero-trust architecture. Which of the following is most aligned with this approach?

Answer: A

Explanation:
Network segmentation supports zero-trust principles by ensuring sensitive systems are isolated and access is restricted based on identity, role, and context. Unlike traditional models, zero-trust architecture does not automatically trust authenticated users or internal network traffic. It enforces strict access controls to minimize risk.


NEW QUESTION # 88
Which of the following explains why a company might reprioritize a vulnerability score? (Select two.)

Answer: A,D

Explanation:
The correct answers are A. System criticality and D. Threat intelligence .
A company may reprioritize a vulnerability score when the affected system is more important to the business than the raw CVSS score alone indicates. A vulnerability on a business-critical system may receive higher priority than the same vulnerability on a low-value system. The CySA+ materials state that vulnerabilities may be prioritized based on system criticality , including the critical nature of the data processed and the business processes that use the host.
Threat intelligence can also cause reprioritization. If intelligence shows that a vulnerability is being actively exploited in the wild or targeted by relevant threat actors, the organization should raise its priority even if the base vulnerability score is not the highest. The Secbay CySA+ guide states that organizations should incorporate threat intelligence to understand the current threat landscape and prioritize vulnerabilities actively exploited in the wild.
Why the other options are incorrect:
B). Alert volume is an incident response or monitoring metric, not a direct reason to reprioritize a vulnerability score.
C). Unexpected outage may affect operations, but it is not a standard vulnerability score reprioritization factor.
E). Patch availability affects remediation planning and timing, but the two strongest score-reprioritization factors in this question are asset/system criticality and threat intelligence.
F). Public relations may affect communications strategy after an incident, but it is not a core vulnerability prioritization factor.


NEW QUESTION # 89
During a routine review, a security analyst identifies an unusual volume of traffic going to a local network workstation. The analyst extracts the traffic to a pcap file. To analyze the content, the analyst runs the command tcpdump -n -r file.pcap udp and port 53 and receives the following output:

Which of the following conclusions will the analyst reach based on the pcap analysis?

Answer: C

Explanation:
The tcpdump filter (udp and port 53) isolates DNS traffic. In the output, the analyst can see DNS queries
/responses, including PTR lookups and NXDomain responses. What makes this suspicious is the context ("unusual volume of traffic") combined with the appearance of encoded/high-entropy-looking content embedded in the DNS-related data in the capture.
This pattern strongly aligns with DNS tunneling, a technique used to move data (including stolen data) inside DNS queries because DNS (port 53) is widely allowed and often less inspected. In other words, the capture indicates a covert channel over DNS consistent with data exfiltration.
The All-in-One CySA+ CS0-003 guide explicitly describes DNS tunneling as an exfiltration method:
Exact extract (All-in-One Exam Guide):
"Domain Name System (DNS) tunneling, for example, is a method of sending data via encoded DNS queries... Hunters will need to keep an eye out for abnormal DNS queries or unusually high query volumes." That maps directly to this scenario:
* You were told there is an unusual volume of traffic.
* The traffic is DNS (UDP/53).
* The output shows encoded/abnormal-looking DNS content, consistent with "sending data via encoded DNS queries." The Sybex CySA+ Study Guide reinforces that DNS queries can be used as covert channels (including encoded/encrypted data inside DNS requests), and that abnormal DNS patterns are IoCs:
Exact extract (Sybex Study Guide):
"DNS tunneling is another potential issue that can be monitored... DNS queries that include encoded or encrypted data are potential IoCs to watch for." Why the other options are not supported by the pcap output
* A (Meterpreter payload delivery): Meterpreter delivery is not something you'd typically conclude from DNS-only traffic unless you see very specific exploit/payload staging indicators; the capture shown is DNS query/response behavior consistent with tunneling, not a clear Meterpreter staging pattern.
* C (SQL injection): SQLi evidence is normally visible in HTTP(S) requests, parameters, URIs, or server responses-nothing in the DNS-only view indicates SQLi payloads.
* D (DNSSEC): DNSSEC would be indicated by DNSSEC-specific records/flags (e.g., DNSKEY/DS
/RRSIG/NSEC, DO bit usage). The shown traffic is not presented as DNSSEC validation traffic; the suspicious element is encoded/high-entropy data consistent with tunneling.
* E (Normal Unix-based traffic): "Normal" is contradicted by the scenario's stated unusual traffic volume and by the presence of encoded/abnormal DNS content consistent with tunneling IoCs.
References (CompTIA CySA+ CS0-003 documents / study guides used):
* Mya Heath et al., CompTIA CySA+ All-in-One Exam Guide (CS0-003): DNS tunneling = sending data via encoded DNS queries; watch for abnormal queries / high volume
* Mike Chapple & David Seidl, CompTIA CySA+ Study Guide (CS0-003): DNS tunneling and DNS queries containing encoded/encrypted data are IoCs
