NEW QUESTION # 233
A developer is trying to retrieve data over a REST API. The API server responds with an HTTP client error response code. After investigating the response the developer realizes the realizes the response has a Retry-After header. What is the root cause of this error?

A. Too many requests were sent to the REST service in a given amount of time.
B. An appliance limited the rate of requests to the transport layer.
C. An appliance limited the rate of requests to the application layer
D. The REST service is unreachable at the time of the REST request

Answer: A

Explanation:
The HTTP client error response code accompanied by a Retry-After header typically indicates that the client has sent too many requests in a given amount of time, leading to rate limiting by the server. This is often indicated by a 429 Too Many Requests status code. The Retry-After header informs the client how long it should wait before making another request.

NEW QUESTION # 236
A developer creates a web application that receives a username and password and uses them to sync the credentials to other services through HTTPS. API keys to services are part of the configuration files of the application, but the credentials to the database that stores the synchronization logs are obtained through an external vault service. What is the security issue in this scenario?

A. The database credentials should be stored in the configuration files so that they are secured on the same server.
B. The API keys are stored in the configuration files but should be stored in the vault service.
C. The synchronization logs should be encrypted and not stored in a relational database.
D. Communication between the application and the services is not encrypted.

Answer: B

Explanation:
The primary security issue in this scenario is that API keys are stored in the configuration files. It is a best practice to store sensitive information such as API keys in a secure vault service rather than in configuration files.
A: Communication between the application and the services is not encrypted - Incorrect. The communication is through HTTPS, which is encrypted. B. The database credentials should be stored in the configuration files so that they are secured on the same server - Incorrect. Database credentials should be securely obtained, as mentioned, through a vault service. C. The API keys are stored in the configuration files but should be stored in the vault service - Correct. Storing API keys in configuration files poses a security risk. They should be stored in a secure vault service. D. The synchronization logs should be encrypted and not stored in a relational database - Incorrect. The issue is not about storing logs in a relational database, but rather the storage of API keys in configuration files.

NEW QUESTION # 238
Refer to the exhibit.

A developer must integrate a bot with an internal communication app. The developer wants to replace the webexbot package with the teamsbot package by using Ansible and prepares a playbook In the first two tasks, the playbook stops the webexbot and verifies that the teamsbot is installed. What is accomplished in the last task of the workflow when the developer runs the Ansible playbook?

A. stops the webexbot service and uninstals it and retains its configuration files
B. installs the webexbot and retains the configuration files
C. searches whether the purge package is available in the repository and uninstalls the webexbot package
D. uninstalls the webexbot package and removes its configuration files

Answer: D

Explanation:
In the Ansible playbook, the last task uses the apt module with state: absent and purge: yes for the webexbot package. This configuration ensures that the package is uninstalled and all associated configuration files are removed. This is different from a simple uninstall, which would leave configuration files behind.
