最新的 CompTIA CySA+ CS0-004 免費考試真題 (Q70-Q75):

問題 #70
Which of the following describes the main benefits of MITRE ATT&CK Navigator?

A. Understanding adversary behavior and identifying gaps in defenses
B. Responding to adversary behavior and building security defense tools
C. Monitoring adversary behavior and performing malware reverse engineering
D. Replicating adversary behavior and blocking gaps in defenses

答案：A

解題說明：
ATT&CK Navigator visualizes adversary tactics and techniques, helping security teams map threat behavior and identify weaknesses in defensive coverage.

問題 #71
A security analyst runs an Nmap scan against a host with multiple open ports using the following command:
nmap 10.10.10.1 -p-
The following output is obtained after the scan:
Starting Nmap 7.95 ( https://nmap.org ) at 2025-07-15 15:55 UTC
Note: Host seems down.
Nmap done: 1 IP address (0 hosts up) scanned in 3.16 seconds
Which of the following is the most accurate way to scan the target IP for open ports?

A. nmap 10.10.10.1 -p80, 443, 445, 9999, 135, 22, 21 -b --traceroute
B. nmap 10.10.10.1/24 -p- -R -O --script=ssl-enum-ciphers
C. nmap -sn -p- 10.10.10.1
D. nmap -p- -Pn 10.10.10.1

答案：D

解題說明：
The original scan fails because Nmap's host-discovery process concludes that the target appears offline before conducting the intended full port scan. Option C adds -Pn , instructing Nmap to skip normal host discovery and proceed with scanning the target as though it is online. The -p- option then instructs Nmap to test the complete TCP port range rather than only its default set.
This is appropriate when a live host does not respond to discovery probes because ICMP echo traffic or other discovery packets may be filtered by firewalls, host-based controls, or network policy. A system can therefore appear "down" to Nmap's discovery phase while still exposing reachable TCP services.
Option B uses -sn, which performs host discovery without a port scan and therefore contradicts the requirement. Option A scans only a limited set of explicitly identified ports and includes unrelated functionality. Option D unnecessarily changes the scope to an entire /24, performs operating-system detection and DNS resolution, and invokes an SSL cipher script; none of those modifications addresses the immediate host-discovery problem.

問題 #72
A vulnerability analyst conducts a security assessment on the Remote Desktop Protocol (RDP) security posture within the environment. The analyst issues the following command for the assessment:
nmap -p 3389 --script rdp* 10.0.0.0/24
The analyst receives responses, which are divided into one of the two categories, from 13 out of the 254 hosts:

Which of the following conclusions can the analyst make about the output on Category 2?

A. The systems are not joined to an Active Directory domain and are using NTLM as an authentication method.
B. The systems are joined to an Active Directory domain and using New Technology LAN Manager (NTLM) as an authentication method.
C. The systems are joined to an Active Directory domain and are using Kerberos as an authentication method.
D. The systems are not joined to an Active Directory domain and are using Kerberos as an authentication method.

答案：A

解題說明：
The rdp-ntlm-info output identifies LOCALHOST as the domain and target name, indicating a local workgroup rather than Active Directory. The script output also confirms NTLM authentication.

問題 #73
Which of the following best describes the main objective of the exploitation phase according to the Cyber Kill Chain methodology?

A. To actively scan for vulnerabilities
B. To destroy logs
C. To send a malicious payload
D. To gain access to a target

答案：D

解題說明：
In the Cyber Kill Chain, the exploitation phase is where the attacker takes advantage of a vulnerability to execute malicious code and gain unauthorized access to the target system. This step follows delivery and represents the point at which the attack successfully compromises the target.

問題 #74
A security analyst reviews the public-facing attack surface of a network that contains both Windows and Linux servers. Which of the following commands is the best way to identify the services running?

A. nmap -sV -pl-1024 -iL hosts.txt
B. nmap -O -p- -iL hosts.txt
C. nmap -sP -A -iL hosts.txt
D. nmap -sn -vvvv -iL hosts.txt

答案：A

解題說明：
Service version detection is required to identify which services are running on hosts. The command includes the service scan option and targets a range of ports, allowing the analyst to enumerate active services and their versions across the listed hosts.
