Linux Foundation Certified IT Associat 認定 LFCA 試験問題 (Q132-Q137):

質問 # 132
A solution must be implemented that establishes a virtual Layer 3 point-to-point link between two data centers over the Internet for the secure (encrypted) transfer of sensitive data. The solution must ensure that data is encrypted at the network layer. Which of the following options meets these requirements?

A. IPsec tunnel configured with AH in the transform set.
B. IPsec with transform-set AH over IP-in-IP tunnel.
C. MACsec protocol configured with AES-GCM encryption.
D. IPsec tunnel configured with ESP in the transform set.

正解：D

解説：
An IPsec tunnel using Encapsulating Security Payload (ESP) provides confidentiality through encryption as well as integrity protection at the network layer. This creates a secure Layer 3 connection over the Internet, making it suitable for transferring sensitive data between data centers. AH provides integrity and authentication but does not encrypt data, so it does not meet the requirement for encrypted network-layer communication.

質問 # 133
A task requires deleting all files within a folder while leaving any subdirectories intact. Which command accomplishes this?

A. rm -r /path/to/folder/*
B. rm -f /path/to/folder/
C. find /path/to/folder -type f -delete
D. find /path/to/folder/ -delete

正解：C

解説：
The command find /path/to/folder -type f -delete targets only files (-type f) within the specified folder and deletes them, leaving directories and subdirectories intact. This makes it the safest option when the requirement is to remove all files without affecting the directory structure.

質問 # 134
Which service model in cloud computing provides virtual machines, networks, and storage?

A. IaaS
B. SaaS
C. PaaS
D. DBaaS

正解：A

質問 # 135
In a multi-tier cloud application, what is the most appropriate way to separate the environments following best practices?

A. Use a single virtual machine with containerized services for all environments to simplify deployment.
B. Create separate virtual networks for production, staging, and testing environments.
C. Host staging and testing in separate subnets but keep production on the same subnet for performance.
D. Use tagged resources within the same virtual network to identify different environments.

正解：B

解説：
Separating production, staging, and testing environments into different virtual networks provides strong isolation, reduces the risk of accidental interference, and allows for independent security controls and policies for each environment, following cloud best practices.

質問 # 136
A system administrator needs to check the status of multiple systemd services at the same time on a Linux server. Which command should be used?

A. systemctl list-units --type=service
B. systemctl status --all
C. systemctl status service1 service2 service3
D. service status service1 service2 service3

正解：C

解説：
systemctl status service1 service2 service3 allows the administrator to check the current status of multiple specified systemd services simultaneously, showing whether they are active, inactive, or failed, along with recent logs for each service.
