CompTIA Cybersecurity Analyst (CySA+) Certification Exam CS0-004 Prüfungsfragen mit Lösungen (Q145-Q150):

145. Frage
Which of the following uses simulated traffic to a website to evaluate performance?

Antwort: C

Begründung:
Synthetic monitoring evaluates website performance by generating simulated user traffic and transactions to test availability, response time, and functionality. This approach allows analysts to proactively measure performance and detect issues without relying on real user activity.


146. Frage
A server was recently compromised. A security analyst needs to collect artifacts for further analysis before disconnecting the server from the network.
Which of the following artifacts should the analyst collect first?

Antwort: A

Begründung:
The analyst should collect the Netstat output first because current network-connection information is highly volatile and will change immediately when the server is disconnected. netstat-type evidence can identify active TCP/UDP connections, listening services, remote endpoints, and potentially the communication channels associated with an attacker or command-and-control infrastructure.
Digital-forensic acquisition follows the order of volatility : evidence most likely to disappear or change should be captured before more persistent artifacts. RFC 3227 explicitly directs investigators to proceed from volatile to less-volatile evidence and identifies information such as routing data, ARP cache, process state, memory-related information, and network state as highly time-sensitive.
The ARP table is also volatile and should be captured early, but the wording "before disconnecting the server from the network" makes active connection state particularly important because those sessions will terminate when network connectivity is removed. ShellBags are persistent forensic artifacts stored within Windows Registry data and can be collected later from disk. A hard-disk image is critical but comparatively nonvolatile and should follow acquisition of live state.
Therefore, live network-session information takes priority.
Study Guide Reference: Incident Response and Management # Evidence Acquisition # Order of Volatility # Live Response # netstat # Network Connections # Forensic Preservation.


147. Frage
Which of the following is the best reason to heavily segment business-critical assets from within the network?

Antwort: A

Begründung:
Legacy systems present a significant security problem because they frequently cannot support current operating systems, security agents, encryption mechanisms, authentication controls, or vendor patches. When a business-critical legacy system cannot be remediated normally, strong network segmentation becomes an important compensating control. The objective is to reduce the system's reachable attack surface and restrict which users, hosts, protocols, and applications can communicate with it.
A segmented legacy asset might be placed in a dedicated VLAN or security zone and protected through restrictive firewall access-control rules, jump hosts, allowlisting, enhanced logging, and continuous monitoring. Even though segmentation does not remove the underlying vulnerability, it decreases exposure and makes exploitation or lateral movement considerably more difficult.
Degraded functionality is generally an effect or remediation constraint rather than the strongest reason for isolation. Asset obfuscation does not provide reliable security because hidden systems can still be discovered through enumeration or traffic analysis. A proprietary server is not automatically vulnerable merely because its implementation is proprietary; it may still support modern patches and security controls.
CS0-004 specifically covers segmentation as a vulnerability-scanning consideration, compensating controls as a mitigation strategy, and legacy systems as an important inhibitor to remediation.
Study Guide Reference: Vulnerability Management # Vulnerability Prioritization and Mitigation # Compensating Controls # Segmentation # Legacy-System Constraints.


148. Frage
A new policy prohibits external access to database servers. A recent external port scan identified the following open Transmission Control Protocol (TCP) ports:
- 21
- 25
- 68
- 80
- 389
- 443
- 587
- 1514
- 3306
- 3389
- 8080
Which of the ports must be closed to be compliant with the new policy? (Choose two.)

Antwort: C,F

Begründung:
Port 3306 is the default port used by MySQL database servers. Allowing external access to this port directly exposes the database service, which violates a policy that prohibits external access to database servers.
Port 3389 is used by Remote Desktop Protocol (RDP). External access through RDP allows direct administrative or user access to the server hosting the database, which effectively bypasses the restriction against external access to database servers and therefore must also be closed to comply with the policy.


149. Frage
Which of the following occurs during the analysis phase of the incident response process?

Antwort: D

Begründung:
During analysis, alerts are validated and triaged to determine the incident's severity, scope, priority, and potential impact. Reimaging is recovery, while isolation is containment.
