NEW QUESTION # 116
The Chief Executive Officer (CEO) has notified that a confidential trade secret has been compromised. Which of the following communication plans should the CEO initiate?
Answer: D
Explanation:
The CEO should initiate an alert to department managers to speak privately with affected staff.
This is because the trade secret is confidential and should not be disclosed to the public.
Additionally, the CEO should verify legal notification requirements of PII and SPII in the legal and human resource departments to ensure compliance with data protection laws.
NEW QUESTION # 117
A forensic analyst is conducting an investigation on a compromised server Which of the following should the analyst do first to preserve evidence''
Answer: B
Explanation:
A forensic analyst is conducting an investigation on a compromised server. The first step that the analyst should do to preserve evidence is to back up all log files and audit trails. This will ensure that the analyst has a copy of the original data that can be used for analysis and verification. Backing up the log files and audit trails will also prevent any tampering or modification of the evidence by the attacker or other parties. The other options are not the first steps or may alter or destroy the evidence.

NEW QUESTION # 118
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: A
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.
Reference (CompTIA CySA+ CS0-003 documents / study guides used):
Mike Chapple & David Seidl, CompTIA CySA+ Study Guide (CS0-003): correlate other events with the initial event; identify involved users/systems/services Secbay Press, CompTIA CySA+ Exam Prep Guide (CS0-003): logs + timestamps build a timeline of events and support analysis of incident progression
NEW QUESTION # 119
A security audit for unsecured network services was conducted, and the following output was generated:
Which of the following services should the security team investigate further? (Select two).
Answer: D,F
Explanation:
Explanation
The output shows the results of a port scan, which is a technique used to identify open ports and services running on a network host. Port scanning can be used by attackers to discover potential vulnerabilities and exploit them, or by defenders to assess the security posture and configuration of their network devices1 The output lists six ports that are open on the target host, along with the service name and version associated with each port. The service name indicates the type of application or protocol that is using the port, while the version indicates the specific release or update of the service. The service name and version can provide useful information for both attackers and defenders, as they can reveal the capabilities, features, and weaknesses of the service.
Among the six ports listed, two are particularly risky and should be investigated further by the security team:
port 23 and port 636.
Port 23 is used by Telnet, which is an old and insecure protocol for remote login and command execution.
Telnet does not encrypt any data transmitted over the network, including usernames and passwords, which makes it vulnerable to eavesdropping, interception, and modification by attackers. Telnet also has many known vulnerabilities that can allow attackers to gain unauthorized access, execute arbitrary commands, or cause denial-of-service attacks on the target host23 Port 636 is used by LDAP over SSL/TLS (LDAPS), which is a protocol for accessing and modifying directory services over a secure connection. LDAPS encrypts the data exchanged between the client and the server using SSL/TLS certificates, which provide authentication, confidentiality, and integrity. However, LDAPS can also be vulnerable to attacks if the certificates are not properly configured, verified, or updated. For example, attackers can use self-signed or expired certificates to perform man-in-the-middle attacks, spoofing attacks, or certificate revocation attacks on LDAPS connections.
Therefore, the security team should investigate further why port 23 and port 636 are open on the target host, and what services are running on them. The security team should also consider disabling or replacing these services with more secure alternatives, such as SSH for port 23 and StartTLS for port 6362
NEW QUESTION # 120
A security analyst is reviewing the findings of the latest vulnerability report for a company's web application. The web application accepts files for a Bash script to be processed if the files match a given hash. The analyst is able to submit files to the system due to a hash collision. Which of the following should the analyst suggest to mitigate the vulnerability with the fewest changes to the current script and infrastructure?
Answer: A
Explanation:
The vulnerability that the security analyst is able to exploit is a hash collision, which is a situation where two different files produce the same hash value. Hash collisions can allow an attacker to bypass the integrity or authentication checks that rely on hash values, and submit malicious files to the system. The web application uses MD5, which is a hashing algorithm that is known to be vulnerable to hash collisions. Therefore, the analyst should suggest replacing the current MD5 with SHA-256, which is a more secure and collision-resistant hashing algorithm.
