An API endpoint is a specific URL or URI where an API can be accessed by a client to perform operations like retrieving or sending data. It defines the location and method (such as GET, POST) for interacting with the API.

The common status codes in HTTP responses are:
- **200**: OK
- **201**: Created
- **204**: No Content
- **400**: Bad Request
- **401**: Unauthorized
- **403**: Forbidden
- **404**: Not Found
- **500**: Internal Server Error
- **502**: Bad Gateway
- **503**: Service Unavailable
CORS, or Cross-Origin Resource Sharing, is a security feature implemented by web browsers that allows or restricts web applications from making requests to a domain different from the one that served the web page. It affects API development by requiring developers to configure their APIs to specify which origins are allowed to access their resources, ensuring that only trusted domains can interact with the API.
API documentation is a technical manual that explains how to use an API, including its endpoints, request and response formats, authentication methods, and examples. It is necessary because it helps developers understand how to integrate and interact with the API effectively, ensuring proper usage and reducing errors.
A web service is a standardized way of allowing different applications to communicate over the internet using protocols like HTTP. It provides a method for applications to exchange data and perform operations. An API (Application Programming Interface) is a set of rules and tools that allows different software applications to interact with each other. A web service is a type of API that specifically uses web protocols to enable this interaction.
CSS can be used by linking a stylesheet to an HTML document using the `<link>` tag in the `<head>` section, by embedding styles directly within a `<style>` tag in the `<head>`, or by applying inline styles directly to HTML elements using the `style` attribute.
To rotate an image in Photoshop, select the image layer, then go to the menu and choose Edit > Transform > Rotate. You can also use the shortcut Ctrl + T (Cmd + T on Mac) to enter Free Transform mode, then move your cursor near a corner until it turns into a curved arrow, and drag to rotate.
A CSS ruleset consists of a selector and a declaration block. The selector targets HTML elements, and the declaration block contains one or more property-value pairs that define the styles to be applied to those elements.
The selector `h1` targets all `<h1>` elements, `.warning` targets all elements with the class "warning", and `#footer` targets the element with the ID "footer".
CSS is needed to separate content from presentation, allowing for better design control, improved website performance, easier maintenance, and consistent styling across multiple pages.
The key element of a Test Plan is the Test Strategy.
You can use Apache NiFi or Talend for bulk data insertion into various tables in test databases, as both tools support DB2, SQL Server, and Oracle.
I have worked with tools such as Nagios, Zabbix, Prometheus, Grafana, and SolarWinds.
Infrastructure as Code (IaC) is a practice that allows you to manage and provision IT infrastructure using code and automation tools. It impacts monitoring by enabling consistent and repeatable environments, making it easier to implement monitoring solutions, automate alerts, and ensure that monitoring configurations are version-controlled and easily reproducible across different environments.
Thresholds and alerts for monitored systems are defined by identifying key performance indicators (KPIs) and setting specific values that indicate normal and abnormal performance. Thresholds are established based on historical data, industry standards, and business requirements. Alerts are configured to trigger notifications when metrics exceed or fall below these thresholds, allowing for timely responses to potential issues.
SNMP, or Simple Network Management Protocol, is a protocol used for managing and monitoring network devices. It allows network administrators to collect and organize information about devices such as routers, switches, and servers, and to manage their performance and configuration. SNMP operates by using a manager to request data from agents on the devices, which respond with the requested information, enabling effective network monitoring and management.
The ELK stack consists of Elasticsearch, Logstash, and Kibana. It is used in infrastructure monitoring to collect, store, analyze, and visualize log data from various sources. Elasticsearch indexes the data, Logstash processes and ingests it, and Kibana provides a user-friendly interface for visualizing and querying the data, helping to identify issues and monitor system performance.
