if you go into wayback machine, search up exam topics, and find the cysa 002 exam, go to january 4th snapshot, and you'll

Going for A here, reasons being following (Put ** around the secrtions in the text):
Vector - Network (Not Asked about)
Complexity - Low (Not Asked about)
Privileges Required - None (A recent zero-day vulnerability is being actively exploited, requires no user interaction or
**privilege escalation**)
User interaction - None (A recent zero-day vulnerability is being actively exploited, **requires no user interaction** or privilege
escalation)
Scope -Unchanged (Not Asked about)
Confidentiality - High (has a significant impact to **confidentiality** and integrity but not to availability)
Integrity - K ? - Typo Perhaps?
Availability - Low (has a significant impact to confidentiality and integrity but not to **availability**)

There is no "K" value for Integrity (I) and Attack Vector (AV), but A has the least amount to unlikely value. Reference:

I took my exam today and passed with a score of 821! Many of the questions here appeared on the exam exactly as they were.
There were 69 questions in total, including 3 PBQs. One PBQ involved ping and nmap commands, while the other PBQs were
new but straightforward to understand and answer.

I just cleared my exam yesterday and I should say that only 30% from this dump came out. I had 5 PBQs and only the Cyber Kill
chain from this dump was on the PBQ section. I had 71 Questions and the first 40 questions are new. Btw I passed with 797
score.

Did you finish all CSO-300 questions here before the exam? I have mine next Saturday and wouldn't mind any help and
direction you can throw my way. Thanks.

ma ggie22 9 months, 4 weeks ago

I have a contributor access here. You'd better review the cso-002 as well, because they get some questions from there too.
Find this PBQ from SurePass. "The developers recently deployed new code to three web servers. A daffy automated external
device scan
report shows server vulnerabilities that are failure items according to PCI DSS". I had this one as well.

Thanks. I cleared it on Saturday. A bit of a brain fog as most of the questions were unexpected. The PBQs were diabolic.

, Selected Answer: A

No privilege is squired. Option B has privilege that makes it completely wrong.
Now option A should have had I:H but it is I:K.
The impact is not high, but at least not low, but it should be high. I now believe A is the best choice ignore by B selection
earlier.

Uncle_Lucifer 1 year, 11 months ago

Also option B has user interaction, while A dosent. Answer is definitely A.
B has 2 wrongs while a has a slight wrong.

CyberJa ck a l 11 months, 3 weeks ago

Correct answer is A as the UI (User Interaction) criteria specifies N for none.

ussliberty 1 year, 8 months ago

K is not a possilbe value, yet it appears in A and B
H is not a possible value for UI, yet it appears in C
R is not a possible value for PR, yet it appears in D
So every statement contains invalid outputs.
The statement tells us the following are true. Therefore, A is the most correct answer.
PR=N
UI=N
C=H
I=H
A=/=H

Selected Answer: B

Answer is B.
Significant impact to C and I (confidentially and integrity) so both should be high. But in A option only C was high while I was K
, not H.
But overall the choices looked screwed. CompTIA exam writers are something in the making

Uncle_Lucifer 1 year, 11 months ago

Both A and B are not accurate. B has the best CIA setup while A has the best vector and privilege setup. This is word. Could be
A or B depending on what criteria is more important

For the given scenario of a recent zero-day vulnerability that is actively exploited, requires no user interaction or privilege
escalation, and has a significant impact on confidentiality and integrity but not on availability, the most accurate CVE metrics
would be:
B. CVSS:31/AV:K/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:L
