Ques:- What are threads (user/kernel)?
Asked In :-
presidio,
Right Answer:
Threads are the smallest units of processing that can be scheduled by an operating system.
- **User Threads**: Managed by user-level libraries and the operating system kernel is unaware of them. They are lightweight and allow for fast context switching but may not utilize multiple processors effectively.
- **Kernel Threads**: Managed directly by the operating system kernel. They can be scheduled on multiple processors and provide better performance for multi-threaded applications, as the kernel can manage them more efficiently.

Ques:- What are Active Directory sites and how do they improve replication efficiency
Asked In :-
Network Intelligence India, Stellantis, HELLA ELECTRONICS CORPORATION, theITSupportCenter, LLC, nasa, avaya, sri lanka telecom, liberty global, bitdefender, zscaler,
Right Answer:
Active Directory sites are physical locations in a network that represent a set of well-connected IP subnets. They improve replication efficiency by allowing domain controllers within the same site to replicate changes more frequently and quickly, reducing the amount of replication traffic over slower WAN links between different sites. This helps optimize network performance and ensures timely updates across the Active Directory environment.

Ques:- How do you create and manage user accounts in Active Directory
Asked In :-
Umbrella Infocare, Network Intelligence India, Inspirisys Solutions, sri lanka telecom, liberty global, sungard availability services, icn, province of new brunswick, transcom, scom,
Right Answer:
To create and manage user accounts in Active Directory, you can use the Active Directory Users and Computers (ADUC) console. Right-click on the desired organizational unit (OU), select "New," then "User" to create a new account. Fill in the required information, set a password, and configure account properties as needed. To manage existing accounts, right-click on the user account to modify properties, reset passwords, or disable/enable accounts. You can also use PowerShell commands like `New-ADUser` for creating and `Set-ADUser` for managing user accounts.

Ques:- What are the differences between Active Directory Domain Services (AD DS) and Active Directory Lightweight Directory Services (AD LDS)
Asked In :-
Network Intelligence India, Network Labs, Stellantis, iron mountain, liberty global, audiocodes, duo security, nca, telnyx, microsoft licensing,
Right Answer:
Active Directory Domain Services (AD DS) is used for managing domain-based networks, providing authentication, authorization, and directory services for users and computers within a domain. Active Directory Lightweight Directory Services (AD LDS), on the other hand, is a directory service that provides directory capabilities without the need for a domain or domain controller, allowing applications to store and retrieve directory data without the full overhead of AD DS.

Ques:- How do you troubleshoot Active Directory replication issues
Asked In :-
Umbrella Infocare, Renault Nissan, Inspirisys Solutions, infoblox, duo security, nca, telnyx, microsoft licensing, province of new brunswick, a2 hosting,
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**

Ques:- What is Group Policy in Active Directory, and how do you use it
Asked In :-
Renault Nissan, Danske IT and Support Services, Gad-A-Get Computers, HELLA ELECTRONICS CORPORATION, dell emc, iron mountain, samsung sds, brennan it, jumpcloud, scom,
Right Answer:
Group Policy in Active Directory is a feature that allows administrators to manage and configure operating system settings, application settings, and user permissions across multiple computers and users in a network. It is used by creating Group Policy Objects (GPOs) that can be linked to Active Directory containers like sites, domains, or organizational units (OUs). Administrators can use it to enforce security settings, deploy software, and manage user environments consistently across the organization.

Ques:- What is the difference between Jenkins and other CI/CD tools like GitLab CI or CircleCI?
Asked In :-
C E I India, Diya Systems (Mangalore), ANR Software, Payoda, Test Yantra, EvolveWare, Softsuave, Reliance Jio, Slk Software Pvt Ltd, Coforge,
Right Answer:
Jenkins is an open-source automation server that allows for extensive customization and integration with various plugins, making it highly flexible. In contrast, GitLab CI is tightly integrated with GitLab repositories, providing a seamless experience for users within that ecosystem, while CircleCI focuses on cloud-based CI/CD with a user-friendly interface and predefined configurations. Jenkins typically requires more setup and maintenance, while GitLab CI and CircleCI offer more out-of-the-box solutions with less configuration needed.
