1

A security analyst reviews SIEM alerts and notices a spike in outbound DNS queries from a single workstation to an unfamiliar external domain. The queries contain unusually long subdomain strings that appear encoded. Which type of attack should the analyst suspect?

AA) DNS cache poisoning
BB) DNS tunneling for data exfiltration
CC) Distributed denial-of-service (DDoS) amplification
DD) ARP spoofing on the local network
2

During a vulnerability assessment, a scanner reports a critical CVE on a production web server running Apache. The vulnerability allows remote code execution. The server hosts the company's primary customer portal. What should the analyst recommend FIRST?

AA) Immediately shut down the web server and apply the patch
BB) Verify the finding is not a false positive, assess exploitability, and evaluate compensating controls before scheduling a patch window
CC) Ignore the finding because vulnerability scanners frequently produce false positives
DD) Open a firewall rule to block all inbound HTTP and HTTPS traffic to the server
3

An incident responder is analyzing a compromised Linux server. They need to collect volatile evidence before powering down the system. Which of the following is the CORRECT order of volatility for evidence collection?

AA) Hard drive image, swap space, network connections, RAM
BB) RAM, network connections, running processes, hard drive image
CC) Running processes, RAM, hard drive image, network connections
DD) Network connections, hard drive image, RAM, swap space
4

A security team completes an incident investigation and is preparing a final report for executive leadership. Which of the following BEST describes what the executive summary section should include?

AA) Full packet captures, log excerpts, and malware hashes from the investigation
BB) A high-level overview of the incident timeline, business impact, root cause, and recommended actions in non-technical language
CC) Detailed technical steps the responders took, including every command executed
DD) A list of all IOCs discovered along with YARA rules for future detection
5

An organization's vulnerability management team discovers that 40% of their Windows endpoints are missing a critical security patch released two weeks ago. The endpoints are spread across multiple business units. According to vulnerability management best practices, what should the team do NEXT?

AA) Immediately force-push the patch to all unpatched endpoints regardless of business impact
BB) Notify the affected business units, coordinate a patching schedule based on asset criticality, and track remediation progress
CC) Wait until the next scheduled patch cycle since the patch has only been out for two weeks
DD) Remove the unpatched endpoints from the network until they can be individually updated

Frequently Asked Questions

What is the CompTIA CySA+ certification?

CompTIA CySA+ (Cybersecurity Analyst) is an intermediate-level cybersecurity certification that validates your ability to detect, analyze, and respond to security threats. It's vendor-neutral and recognized globally - kind of the natural next step after Security+. The current version is CS0-003, and it focuses heavily on security operations, vulnerability management, incident response, and reporting.

How many questions are on the CySA+ CS0-003?

The CySA+ CS0-003 has a maximum of 85 questions. You'll get a mix of multiple-choice and performance-based questions (PBQs). The PBQs are hands-on scenarios where you might need to analyze log output, interpret scan results, or work through an incident response situation. They're tougher than standard multiple-choice, so don't save them all for the end.

What score do I need to pass the CySA+?

You need a 750 on a 100-900 scale to pass the CySA+ CS0-003. CompTIA uses scaled scoring, so it's not a simple percentage calculation. Some questions carry more weight than others, and the performance-based questions can have a bigger impact on your final score than regular multiple-choice items.

How much does the CySA+ cost?

The CySA+ voucher runs $404 USD as of 2026. That covers the registration fee only - study materials and practice questions are separate. It's worth checking if your employer offers certification reimbursement before you pay out of pocket. CompTIA also runs bundle deals from time to time that can save you a bit.

What are the CySA+ CS0-003 domains?

The CS0-003 covers four domains: Security Operations (33%), Vulnerability Management (30%), Incident Response and Management (20%), and Reporting and Communication (17%). Security Operations is the biggest chunk, so you'll want to spend extra time on threat detection, SIEM analysis, and monitoring concepts. But don't neglect Reporting - it's smaller in percentage but shows up heavily in performance-based questions.

How long should I study for the CySA+?

Plan on about 6-10 weeks of study if you already hold the Security+ and have some hands-on experience. If you're coming in without much practical cybersecurity background, 3-4 months is more realistic. Focus on practice questions, log analysis scenarios, and hands-on labs rather than just reading textbooks. The CySA+ tests applied knowledge, so you need to actually work through scenarios - not just memorize definitions.

Is the CySA+ harder than the Security+?

Yes, noticeably. The CySA+ is an intermediate certification while Security+ is entry-level. CySA+ questions tend to be more scenario-based and expect you to apply concepts rather than just recall facts. You'll need to analyze log outputs, interpret vulnerability scan results, and make judgment calls about incident response. If Security+ was like a vocabulary quiz, CySA+ is more like a case study analysis.

What jobs can I get with the CySA+ certification?

CySA+ qualifies you for roles like cybersecurity analyst, SOC analyst (Tier II/III), threat intelligence analyst, vulnerability analyst, and incident response handler. Salary ranges typically fall between $70,000-$110,000 depending on location and experience. It also satisfies DoD 8570 requirements for certain CSSP roles, making it valuable for government and defense contractor positions.
