NEW QUESTION # 156
A security operations center receives the following alerts related to an organization ' s cloud tenant:
Which of the following should an analyst do first to identify the initial compromise?
Answer: C
Explanation:
To identify the initial compromise, the analyst should start with the earliest suspicious activity in the timeline and pivot into the audit logs for the principal (identity) associated with that first alert.
Here, the first notable event is 02:00 excessive API failures tied to jdoe12@myorg.com. That commonly indicates password guessing, token misuse, or other authentication abuse attempts. The next events (02:15 metadata service access, 05:10 mass VM creation by a service account, 05:40 malware) look like follow-on activity after an initial foothold. Therefore, the best first step is to check whether those API failures were followed by any successful API calls by that user and then correlate those successful actions to the later stages in project staging-01.
This approach aligns with CySA+ guidance that analysts should use logs + timestamps to build a timeline and correlate events across identities/systems to understand scope and progression:
* Sybex emphasizes correlating events from multiple sources and using that correlation to determine scope and impact:Exact extract (Sybex Study Guide): "Security analysts are often asked to help analyze that data... Knowing if other events are correlated with the initial event... [and] understanding what systems, users, services, or other assets were involved..."
* Secbay underscores that logs and timestamps are key to forming an accurate incident timeline (which is exactly what we're doing by starting from the earliest alert):Exact extract (Secbay Press): "System and application logs with timestamps help create a timeline of events, aiding in understanding when specific actions occurred during the incident." Why Option B is best vs. the others
* B starts with the earliest suspicious identity and seeks successful API activity that would confirm compromise and explain subsequent actions (metadata access # service account actions # malware).
* A is too broad initially ("all activity under project staging-01") and anchors on a VM that only appears later; it's not the best first pivot when you already have an earlier suspect identity.
* C starts at the compute-instance phase (05:10) rather than the earliest authentication/API anomaly (02:
00), so it's more likely to find post-compromise actions rather than the initial entry.
* D anchors on a specific later VM (fd031f) and compute APIs, again likely after the initial compromise.

NEW QUESTION # 157
During a scan of a web server in the perimeter network, a vulnerability was identified that could be exploited over port 3389. The web server is protected by a WAF. Which of the following best represents the change to overall risk associated with this vulnerability?
Answer: A
Explanation:
Port 3389 is commonly used by Remote Desktop Protocol (RDP), which is a service that allows remote access to a system. A vulnerability on this port could allow an attacker to compromise the web server or use it as a pivot point to access other systems. However, if the firewall blocks this port, the risk of exploitation is reduced.
NEW QUESTION # 158
The security analyst received the monthly vulnerability report. The following findings were included in the report:
- Five of the systems only required a reboot to finalize the patch
application
- Two of the servers are running outdated operating systems and cannot
be patched
The analyst determines that the only way to ensure these servers cannot be compromised is to isolate them. Which of the following approaches will best minimize the risk of the outdated servers being compromised?
Answer: A
Explanation:
Compensating controls are the best approach to minimize the risk of the outdated servers being compromised, as they can provide an alternative or additional layer of security when the primary control is not feasible or effective. Compensating controls are security measures that are implemented to mitigate the risk of a vulnerability or an attack when the primary control is not feasible or effective. For example, if the servers are running outdated operating systems and cannot be patched, a compensating control could be to isolate them from the rest of the network, or to implement a firewall or an intrusion prevention system to monitor and block any malicious traffic to or from the servers. Compensating controls can help reduce the likelihood or impact of an exploit, but they do not eliminate the risk completely. Therefore, the security analyst should also consider upgrading or replacing the outdated servers as soon as possible.
NEW QUESTION # 159
An employee is no longer able to log in to an account after updating a browser. The employee usually has several tabs open in the browser. Which of the following attacks was most likely performed?
Answer: A
Explanation:
CSRF is an attack that forces an end user to execute unwanted actions on a web application in which they're currently authenticated. An attacker may trick the user into clicking a malicious link or submitting a forged form that performs an action on the user's behalf, such as changing their password or transferring funds. If the user has several tabs open in the browser, they may not notice the CSRF request or the resulting change in their account. Updating the browser may have cleared the user's cache or cookies, preventing them from logging in to their account after the CSRF attack.
NEW QUESTION # 160
