When a REST API limits the amount of data returned in a response, it often uses pagination. Pagination breaks the response into smaller, more manageable chunks, allowing the client to retrieve the data in multiple requests.

Pagination: Limits the number of records returned in a single response, requiring additional requests to retrieve subsequent records.

Payload limit: Restricts the size of the response payload but is not the specific feature for controlling record count.

Rate limiting: Controls the number of requests a client can make in a given time period.

Service timeouts: Define how long the server will wait for a request to complete before timing out.

git add .

git commit -m “this is my edit”

git push

In NETCONF, the operation retrieves all or part of a configuration and state data from the running datastore. The operation retrieves configuration data from a specific configuration datastore (e.g., running, startup). These operations correspond to the RESTCONF GET operation, which is used to retrieve configuration and state data from a network device. This mapping between NETCONF and RESTCONF operations is described in detail in the RFC 6241 for NETCONF and RFC 8040 for RESTCONF.

Docker-based applications offer several security benefits:

Easier to Patch: Docker containers include only the dependencies required by the application, making it easier to identify and patch vulnerabilities. This minimizes the attack surface and simplifies the management of security updates.

Separation of Applications: Docker containers enable the separation of applications that traditionally run on the same host. This isolation improves security by reducing the risk of one compromised application affecting others on the same host.

To start a new branch in Git for developing a fix, the git checkout -b my-bug-fix command is used. This command creates a new branch called "my-bug-fix" and checks it out in one step, allowing you to start working on it immediately.

git checkout -b my-bug-fix combines the creation of the branch (git branch my-bug-fix) and switching to it (git checkout my-bug-fix) into a single command.

Version control software offers numerous benefits to development teams. Key advantages include:

Comparisons between revisions of source code files: Version control allows developers to compare different versions of source code files, track changes, and identify what modifications were made and by whom. This is essential for debugging and maintaining code quality.

Access to current code and history for new team members: New team members can quickly get up to speed by accessing the current version of the code and the entire history of changes. This transparency facilitates onboarding and improves collaboration among team members.

For Basic Authentication in REST APIs, the Base64 encoded credentials must be included in the header of the HTTP request. The correct method is to include the following header in the request:

Authorization: Basic am9objowMTlzNDU2Nzg=

Edge computing solutions are utilized where low latency is needed. Edge computing involves processing data closer to where it is generated (at the edge of the network), which reduces the latency compared to sending data to a centralized data center for processing.

Low Latency Needs: Edge computing is designed to provide real-time data processing and decision-making by reducing the distance data has to travel. This is crucial for applications requiring immediate data processing, such as IoT devices, autonomous vehicles, and real-time analytics.
