問題 #116
An analyst reviews the following log entries:

Which of the following conclusions should the analyst reach? (Choose two.)

A. Host ws-57 is communicating on a service using a non-standard port.
B. Domain Controller dc-1 is performing a network scan against ws-57.
C. Host ws-57 is performing a network scan against dc-1.
D. Domain Controller dc-1 is communicating using a non-standard port.
E. Host ws-57 delivered a phishing email via Simple Mail Transfer Protocol.
F. Domain Controller dc-1 is infected with ransomware and initiating connections with ws-57.

答案：A,C

解題說明：
The log relationships support two conclusions: ws-57 is scanning dc-1 , and ws-57 is communicating with a service through a non-standard port . Network scanning is normally identified when one source system attempts connections against multiple ports or services on another host over a short period. Here, the directionality of the recorded communications identifies ws-57 as the initiating host and dc-1 as the target, supporting option A rather than B.
Port numbers then need to be interpreted in context. Standard service-port mappings provide useful baselines, but a service can technically operate on a port different from its conventional assignment. Detection logic therefore needs to consider both the actual port number and the protocol or service identified in the traffic.
Nmap, for example, classifies scanned ports according to states and attempts to associate ports with known services during network reconnaissance.
The entries do not provide sufficient behavioral evidence for phishing delivery or ransomware infection.
Those conclusions would require additional indicators such as SMTP message evidence, malicious attachments, encryption activity, process execution, or endpoint telemetry.
The correct analytical approach is to determine source, destination, connection pattern, and port/service relationship before assigning malicious intent.

問題 #117
The Chief Information Security Officer (CISO) reviews the following security operations metrics from the last month:

Which of the following is the best action to improve overall security operations efficiency?

A. Perform internal incident training on the most common alerts from security information and event management (SIEM).
B. Leverage a cloud security posture management tool to add asset context to alerts.
C. Implement playbooks for the junior analysts to use during investigations.
D. Analyze and tune the detections that are causing non-actionable alerts.

答案：D

解題說明：
The large number of alerts and investigations compared with only five confirmed incidents indicates excessive non-actionable alerts. Tuning detection rules reduces false positives and unnecessary analyst workload.

問題 #118
The threat intelligence team is using the MITRE ATT&CK framework to map threat actors' TTPs to the team's internal reference library. Which of the following best describes the reason visualization and stage alignment are helpful for the IR team?

A. Knowing the attack stage helps the IR team determine how to structure custom SIEM alerts to detect security events of interest
B. Having a common framework provides structure for relaying the known indicators of concern to the security monitoring team
C. Aligning an action to a specific stage in an incident allows the IR team to better define intent and anticipate the next action
D. A visual mapping helps the IR team identify the stage and relevant TTPs faster than a white paper for each threat actor

答案：C

解題說明：
Mapping TTPs to specific MITRE ATT&CK stages helps incident responders understand an adversary's intent, determine where the attack is in its lifecycle, and anticipate likely next actions.
This allows the IR team to respond more effectively and proactively by focusing on techniques that commonly follow the observed activity.

問題 #119
Which of the following tools provides logs that show user access to prohibited cloud storage, identifying whether a file was downloaded to a personal device?

A. CASB
B. EDR
C. SDN
D. SASE

答案：A

解題說明：
A Cloud Access Security Broker (CASB) provides visibility into cloud application usage and user activity. It can monitor access to sanctioned and unsanctioned cloud storage services, track file uploads and downloads, and generate logs showing whether sensitive data was accessed or transferred to personal devices.

問題 #120
Which of the following best explains why sensitive data should be encrypted at rest on laptops?

A. To ensure the integrity of the data on the company network
B. To protect disclosure of information if physical devices are stolen
C. To prevent end users from copying data to other systems
D. To comply with regulatory and legal requirements

答案：B

解題說明：
Encryption at rest protects the confidentiality of stored data by preventing unauthorized access when a laptop or its storage device is lost or stolen.
