Right Answer:
To handle Active Directory backups and restores, use the Windows Server Backup tool to create system state backups, which include Active Directory data. For restoration, boot the server in Directory Services Restore Mode (DSRM) and use the Windows Server Backup to restore the system state. Always ensure you have a recent backup before making changes to Active Directory.

Right Answer:
A Domain Controller (DC) in an Active Directory environment is a server that manages user authentication and access to resources within the domain. It stores the Active Directory database, which contains information about users, groups, computers, and policies, and it processes login requests, enforces security policies, and replicates data across other DCs in the domain.

Right Answer:
To manage Active Directory permissions and access control, use the following steps:

1. **Organizational Units (OUs)**: Create OUs to organize users, groups, and resources logically.
2. **Groups**: Use security groups to assign permissions to multiple users at once.
3. **Delegation of Control**: Use the Delegation of Control Wizard to assign specific permissions to users or groups for OUs.
4. **Access Control Lists (ACLs)**: Modify ACLs on objects to define who can access or modify them.
5. **Group Policy Objects (GPOs)**: Apply GPOs to enforce security settings and permissions across users and computers.
6. **Regular Audits**: Periodically review permissions and access rights to ensure compliance and security.

Right Answer:
To troubleshoot Active Directory replication issues, follow these steps:

1. **Check Replication Status**: Use the command `repadmin /replsummary` to get an overview of replication health.
2. **Verify Connectivity**: Ensure that domain controllers can communicate with each other over the network (check firewalls, DNS, etc.).
3. **Check Event Logs**: Look at the Event Viewer on domain controllers for replication-related errors.
4. **Use Repadmin Tools**: Run `repadmin /showrepl` to see the replication status for each domain controller.
5. **DNS Configuration**: Ensure that DNS is properly configured and that domain controllers can resolve each other’s names.
6. **Force Replication**: Use `repadmin /syncall` to manually trigger replication and check for errors.
7. **Check Site and Services**: Verify that the Active Directory Sites and Services are correctly configured and that replication schedules are appropriate.
8. **Review Active Directory Health**

Right Answer:
Organizational Units (OUs) are containers in Active Directory that help organize and manage users, groups, computers, and other resources. They allow administrators to delegate permissions, apply Group Policies, and structure the directory in a way that reflects the organization’s hierarchy, making management more efficient and organized.

Right Answer:
HTTP methods are standardized request types used in APIs to perform actions on resources. The main methods are:

1. **GET**: Retrieve data from a server.
2. **POST**: Send data to a server to create a new resource.
3. **PUT**: Update an existing resource on the server.
4. **DELETE**: Remove a resource from the server.
5. **PATCH**: Apply partial modifications to a resource.

These methods define the action to be performed on the specified resource in the API.

Right Answer:
Synchronous API calls wait for the response before moving on to the next task, while asynchronous API calls allow the program to continue executing other tasks while waiting for the response.

Right Answer:
RESTful principles include:

1. **Statelessness**: Each API call must contain all the information needed to understand and process the request, with no stored context on the server.
2. **Client-Server Architecture**: The client and server are separate, allowing for independent development and scalability.
3. **Uniform Interface**: A consistent way to interact with resources, typically using standard HTTP methods (GET, POST, PUT, DELETE).
4. **Resource-Based**: APIs should expose resources (data entities) through URIs, and clients interact with these resources.
5. **Representation**: Resources can be represented in various formats (like JSON or XML), and clients can request the format they prefer.
6. **Cacheability**: Responses should indicate whether they can be cached to improve performance and reduce server load.

These principles guide the design of APIs to be scalable, efficient, and easy to use.

Right Answer:
Webhooks are user-defined HTTP callbacks that are triggered by specific events in a web application, allowing real-time data transfer. They differ from APIs in that APIs require a request to be made to receive data, while webhooks automatically send data when an event occurs without needing a request.

Right Answer:
API authentication is the process of verifying the identity of a user or application trying to access an API. Common methods include:

1. **API Keys**: Unique keys provided to users to access the API.
2. **Basic Authentication**: Uses a username and password encoded in Base64.
3. **OAuth**: A token-based authentication method that allows users to grant limited access to their resources without sharing credentials.
4. **JWT (JSON Web Tokens)**: A compact, URL-safe means of representing claims to be transferred between two parties, often used for stateless authentication.
5. **HMAC (Hash-based Message Authentication Code)**: Uses a secret key to create a hash of the request, ensuring data integrity and authenticity.

Right Answer:
Enteric-coated tablets are designed to dissolve in the intestine rather than the stomach, protecting the drug from stomach acid and preventing stomach irritation. Normal-coated tablets dissolve in the stomach.

Right Answer:
I would highlight the benefits of staying with Airtel, such as superior network coverage, better customer service, exclusive offers, and loyalty rewards. I would also address any specific concerns they have and offer solutions to improve their experience with Airtel.

Right Answer:
HR (Human Resources) focuses on managing employee relations, recruitment, and compliance with labor laws, while HRD (Human Resource Development) emphasizes training, development, and improving employee skills for organizational growth.

Right Answer:

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.

Right Answer:

Key metrics to monitor on a server include:

1. CPU Usage
2. Memory Usage
3. Disk I/O
4. Network Traffic
5. Disk Space Utilization
6. System Load Average
7. Process Count
8. Error Rates
9. Temperature and Power Usage
10. Application Performance Metrics

Right Answer:

IT infrastructure monitoring is the process of continuously observing and managing the hardware, software, networks, and services that make up an organization's IT environment. It is important because it helps ensure system performance, identifies issues before they escalate, minimizes downtime, enhances security, and supports efficient resource management.

Right Answer:

The components of IT infrastructure that should be monitored include:

1. Servers
2. Network devices (routers, switches, firewalls)
3. Storage systems
4. Applications and services
5. Databases
6. Virtual machines and containers
7. Cloud resources
8. End-user devices (desktops, laptops, mobile devices)
9. Power and cooling systems
10. Security systems and logs

Right Answer:

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.
