質問 # 11
Which of the following HTTP methods are used by REST? (Choose three correct answers.)

A. CREATE
B. GET
C. PUT
D. DELETE
E. REPLACE

正解：B、C、D

解説：
REST (Representational State Transfer) is an architectural style for designing networked applications. It relies on a stateless, client-server, cacheable communications protocol -- the HTTP protocol. The main HTTP methods used in REST are:
* GET: This method is used to retrieve data from a server at the specified resource.
* PUT: This method is used to update or create a resource at the specified URL.
* DELETE: This method is used to remove a specified resource.
The other options are not standard HTTP methods used in REST:
* CREATE: This is not a standard HTTP method. The equivalent standard method for creating resources is POST.
* REPLACE: This is not a standard HTTP method. The equivalent standard methods for replacing resources are PUT or PATCH.

質問 # 14
A service should be provided to arbitrary clients on the Internet using HTTPS. Any standard client on the Internet should be able to consume the service without further configuration. Which of the following approaches can be used to implement these requirements? (Choose three correct answers.)

* C. Using a certificate issuing service (e.g., Let's Encrypt) allows each server to obtain a valid, trusted certificate, ensuring secure HTTPS communication.
* D. A load balancer can handle HTTPS termination, decrypting incoming HTTPS requests and forwarding them as plain HTTP to backend servers.
* E. Installing a wildcard certificate on all backend servers ensures that each server can handle HTTPS requests using the same certificate, simplifying management.

質問 # 17
Which of the following kinds of data are suitable as artifacts in a continuous delivery pipeline? (Choose three correct answers.)

A. Executable applications such as .exe files or .jar packages.
B. Compiled packages to be installed by a Linux package manager.
C. Docker container images which contain an application.
D. Copies of the contents of source code repositories.

正解：A、B、C

解説：
In a continuous delivery pipeline, artifacts are the final outputs produced during the build and integration stages. These artifacts are then deployed to different environments for testing and production.
* Executable Applications: Artifacts can include executable files like .exe or .jar packages that are ready to be run.
* Compiled Packages: Precompiled packages for installation via package managers (e.g., .deb or .rpm files) are suitable artifacts.
* Docker Images: Docker container images encapsulate the application and its dependencies, making them ideal artifacts for consistent deployment across environments.

質問 # 19
Which section of the Prometheus configuration defines which nodes are monitored?

A. rules
B. scrape_config
C. nodes
D. listener
E. targets

正解：B

解説：
In Prometheus, the scrape_config section of the configuration file defines how and which nodes (targets) should be scraped (monitored). This section specifies the endpoints Prometheus should scrape, the frequency of scraping, and any relabeling configurations.

The other options are incorrect:
* B. targets: This is part of scrape_config but not a top-level configuration section.
* C. rules: This section is used to define alerting and recording rules, not targets.
* D. listener: This is not a standard section in Prometheus configuration.
* E. nodes: This is not a standard section in Prometheus configuration.

質問 # 21
Consider the following Kubernetes Deployment:

With the ReplicaSet:

And the Pods:

What happens if one of the Pods is terminated with the command kubect1 pod delete?

A. The remaining Pods are stopped and the Deployment switches to the state Failed.
B. The ReplicaSet immediately starts a new replacement Pod.
C. The remaining Pods are stopped and a new ReplicaSet is started.
D. The Deployment switches to the state Degraded.
E. The number of replicas in the ReplicaSet is changed to 4.

正解：B

解説：
In Kubernetes, a Deployment manages ReplicaSets and ensures that the specified number of replicas for a given Pod is always maintained. If a Pod managed by a ReplicaSet is terminated (e.g., using the command kubectl delete pod <pod-name>), the ReplicaSet detects the discrepancy in the desired state (number of replicas) and the actual state. As a result, the ReplicaSet will immediately create a new Pod to replace the terminated one and maintain the desired number of replicas.
* Deployment Management: A Kubernetes Deployment is responsible for maintaining the desired state of Pods through ReplicaSets.
* ReplicaSet Functionality: A ReplicaSet ensures that a specified number of Pod replicas are running at all times.
* Pod Termination: When a Pod is terminated, the ReplicaSet notices the reduction in the number of running Pods.
* Replacement Pod Creation: To restore the desired state, the ReplicaSet automatically creates a new Pod to replace the terminated one.

* Kubernetes Documentation - Deployments
* Kubernetes Documentation - ReplicaSet

質問 # 22
Which statement in a Dockerfile defines which command should be started in the container by default when it is started?
(Specify ONLY the statement's name without any values or parameters.)

正解：

解説：
ENTRYPOINT
Explanation:
In a Dockerfile, the ENTRYPOINT instruction is used to specify the command that will be executed when a container starts. Unlike CMD, which can be overridden by arguments provided in docker run, ENTRYPOINT ensures that the specified command is always run.
