Three of the 641 questions in this pack

Question 1

A recent zero-day vulnerability is being actively exploited, requires no user interaction or privilege escalation, and has a significant impact to confidentiality and integrity but not to availability.

Which of the following CVE metrics would be most accurate for this zero-day threat?

  1. CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N
  2. CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:L
  3. CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:H/A:H
  4. CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:H
Show answer and explanation

Correct answer: A. CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

The described threat is remotely exploitable, needs no privileges and no user interaction, and impacts confidentiality and integrity heavily while leaving availability untouched. Option A maps exactly to that profile: AV:N (network attack vector, consistent with active remote exploitation), AC:L (low complexity, as seen with a zero-day being exploited at scale), PR:N (no privilege escalation required), UI:N (no user interaction), S:U (unchanged scope), C:H and I:H (significant confidentiality and integrity loss), and A:N (no availability impact). No other vector combines all of these values.

Why the other options are wrong

  • B. It requires high privileges (PR:H) and user interaction (UI:R), and it lists an availability impact (A:L), contradicting the scenario.
  • C. It requires user interaction (UI:R), understates confidentiality loss (C:L), and adds a high availability impact the scenario says does not exist.
  • D. It restricts the attack to local access (AV:L), requires privileges and user interaction, and shows high availability impact with only low integrity impact.

Question 2

Which of the following tools would work best to prevent the exposure of PII outside of an organization?

  1. PAM
  2. IDS
  3. PKI
  4. DLP
Show answer and explanation

Correct answer: D. DLP

Data Loss Prevention (DLP) is specifically designed to monitor, detect, and prevent unauthorized transmission of sensitive information including PII outside organizational boundaries. DLP tools scan data in motion and at rest to enforce policies against exfiltration. PAM manages privileged access, IDS detects intrusions, and PKI manages encryption, none are designed to specifically prevent PII exposure.

Why the other options are wrong

  • A. PAM controls privileged account access but doesn't prevent data exfiltration
  • B. IDS detects network intrusions but doesn't prevent sensitive data disclosure
  • C. PKI manages certificates and encryption but doesn't monitor for data exposure

Question 3

Which of the following items should be included in a vulnerability scan report? (Choose two.)

  1. Lessons learned
  2. Service-level agreement
  3. Playbook
  4. Affected hosts
  5. Risk score
  6. Education plan
Show answer and explanation

Correct answer: D, E. Affected hosts; Risk score

Affected hosts (D) and risk scores (E) are essential components of vulnerability scan reports as they identify which systems are vulnerable and prioritize remediation efforts. Lessons learned, playbooks, SLAs, and education plans are post-scan activities or separate documentation components, not standard elements of the scan report itself.

Why the other options are wrong

  • A. Lessons learned are derived after remediation, not part of initial scan output
  • B. SLAs are contractual terms, not vulnerability scan data
  • C. Playbooks are incident response procedures, not scan report contents
  • F. Education plans are developed separately from technical scan results

    This exam is very hard without this

    Exam cleared! Honestly this helped a lot. Thank you so much. This exam is nearly impossible to pass without something like this dump.

  2. E Munn –

    Passed my exam

    Spent a few days on this and passed. Very happy with this purchase. All I did was go through this dump three times and then sit my exam. Highly recommend.

  3. leon rowe –

    Passed my exam last week

    Finally passed! Passed my exam last week! Honestly more questions came out than I expected. Recognized content throughout the whole exam, PBQs included. If you are on the fence just get it.

  4. Sandeep Duke –

    Passed

    Got my pass! Ended up doing four read throughs because I kept finding things I had missed. Would not do my prep any other way now.

  5. IGOR NOEL –

    Genuinely impressed

    Recognized so many questions in the exam. Passed on my first attempt!

  6. joel munn –

    Highly recommend

    Passed! Been recommending this dump to everyone at work.

  7. aiden kobayashi –

    Helped me prepare properly

    Finally passed! Thank you. The dump did what it said it would do.

  8. Divya Moore –

    Just buy it

    Passed on second attempt! If you compare the price of this dump to the cost of retaking the exam it is a very easy decision. Just buy it.

  9. Ewa Herrera –

    Passed first try

    Got the pass. A lot of the questions are phrased exactly like the real exam. Really accurate

  10. ON –

    Reliable dump

    Genuinely impressed. Read the explanations even when you get the question right. Sometimes the reasoning reveals something you would have missed.

  11. SIMON WÓJCIK –

    More cost-effective than anything else I tried

    Genuinely grateful. I have spent way more on study materials that helped me less. This dump is easily the most cost effective thing I have bought for cert prep.

  12. Walt Kim –

    A lot came out in the real exam

    This helped more than I expected. I check this site every time I have a new cert coming up. Has not let me down yet.

  13. Joel Mueller –

    Passed with limited study time

    Thanks! I dont have much time to study but I still managed to pass because of this dump. Great resource for people who need to be efficient.

  14. Sofia Noel –

    Clearly based on real exam content

    Thanks, cleared the exam! Used this alongside a practice exam from another source. The overlap was noticeable. This dump is clearly based on real exam content.

  15. P Laurent –

    Very close to the actual exam

  16. Andrzej Adams –

    Highly recommend

    Appreciate the work that went into this. Very happy with this purchase. Would recommend it to anyone sitting this cert.

  17. Yemi Rossi –

    Just passed

    If you are sitting this exam, get this. It's the real deal.

  18. Kumar –

    Wish I had this earlier

    A lot came out in my actual exam. This dump is the real deal. Would have been useful to have found this dump before my first attempt. Lesson learned. Using it for every cert going forward.

  19. Huseyin Moore –

    An honest review

    Did not expect it to be this accurate. Cheap for what it is. The CYSA+ exam costs a lot so spending a small amount on this dump is just sensible. Honest recommendation.

  20. G Dąbrowski –

    Helped me pass on first attempt

    Cannot recommend this enough.

  21. Paul Brown –

    Surprisingly deep question bank

  22. Milo Park –

    Covers what you need to know

  23. Maverick –

    I just passed my CySA+ exam and these dumps were a huge help. The questions were very similar to the real test, and the explanations made it easy to understand the concepts instead of just memorizing answers. On exam day I felt confident, recognized many of the formats, and managed my time well. Definitely worth it if you’re serious about clearing CySA+.

  24. Rania –

    Good for the cost

  25. Camille Blanco –

    Just passed

    Got my result. Passed!

  26. Pearl –

    Passed comfortably

    Passed using this dump!

  27. Zelda Eaton –

    Solid dump

  28. lena grant –

    Does the job

  29. Nate –

    Well worth it

  30. Kaito –

    I passed

    Great resource

  31. Lena Laurent –

    Helped me focus my study

What makes the CySA+ CS0-003 hard

Sitting the exam after December 2026? You want CS0-004 instead: CompTIA retires the English CS0-003 exam on 22 December 2026 (translated versions 23 March 2027). This pack is for candidates booked on CS0-003 before those dates.

CySA+ is not the kind of exam you can get through on general security knowledge. It is a scenario-heavy, analyst-focused exam that tests your ability to interpret SIEM output, triage alerts, prioritise vulnerabilities and walk through an incident response, not just define the concepts. Performance-based questions put you in simulated SOC environments and ask you to make the call.

The candidates who fail CySA+ are usually experienced security professionals who underestimated how specifically CompTIA frames its analyst scenarios. Knowing the MITRE ATT&CK framework is not the same as knowing how CS0-003 asks about it, and this pack has 641 practice questions built around exactly that framing.

About the exam

The CompTIA CySA+ is CompTIA's intermediate-level cybersecurity certification, sitting between Security+ and SecurityX. It validates the ability to detect, analyse and respond to threats through continuous security monitoring, covering security operations, vulnerability management, incident response and reporting. DoD 8140 approved across multiple analyst and responder work roles including SOC analyst, threat intelligence analyst and vulnerability assessment analyst. Four years of hands-on security experience is recommended. CS0-003 is the V3 exam: the English exam retires 22 December 2026, and the Japanese, Portuguese and Spanish exams retire 23 March 2027. The replacement is CS0-004 (V4), which launched 23 June 2026.
