System Administrators (also known as sysadmins) - are information technology (IT) professionals who make sure an organization’s computer systems are functioning and meet the needs of the organization. Sys admins support, troubleshoot, and maintain computer servers and networks. Becoming a system administrator will entail learning some specialized skills. Systems administration is the field of IT that’s responsible for maintaining reliable computers systems in a multi-user environment.
System administrators play a big role and have a lot of responsibility at the organization they are working for. They are responsible for the upkeep and maintenance of the company’s servers that the organization functions on. It’s a big role, which is why companies are only looking to hire professionals who have the right qualifications and educational background. System administration certification training courses give employees the chance to become qualified in the field and become expert system administrators at their enterprise.
Uplatz provides this end-to-end career path consisting of a series of self-paced courses that will help you become a System Administrator.
This course will transition you from working on a single computer to an entire fleet. Earning a certification can bring you needed experience and enhance your resume. There are certain skills that many Systems Administrators have in order to accomplish their responsibilities. By taking a look through resumes, we were able to narrow down the most common skills for a person in this position. We discovered that a lot of resumes listed Analytical skills, Communication skills and Problem-solving skills. In this course, you’ll learn about the infrastructure services that keep all organizations, big and small, up and running.
We’ll deep dive on cloud so that you’ll understand everything from typical cloud infrastructure setups to how to manage cloud resources. You'll also learn how to manage and configure servers and how to use industry tools to manage computers, user information, and user productivity.
A professional certificate in Systems Administration might help you prepare for a job as a system administrator. The subjects covered in this course include network, database, and web management. Shell scripts for system administration chores in all modern server operating systems, as well as user account management, security, printing, disc setup, and backup procedures, are among them. Both Windows and Linux systems are covered in terms of hardware requirements, software compatibility, administrative and technical practises for system security, process management, performance monitoring and tuning, storage management, data backup and restoration, and disaster recovery and prevention.

The System Administrator Certification ensures you know planning, production and measurement techniques needed to stand out from the competition.
Network and computer systems administrators are responsible for the day-to-day operation of these networks. They organize, install, and support an organization's computer systems, including local area networks (LANs), wide area networks (WANs), network segments, intranets, and other data communication systems.
System administration is the field of work in which someone manages one or more systems, be they software, hardware, servers or workstations. Its goal is ensuring the systems are running efficiently and effectively.
A Junior Systems Administrator usually needs to have a technical certificate, like Microsoft MCSE, but many employers prefer that the candidate hold a college degree of some sort, such as a Bachelor's, in a relevant subject like Information Systems, Computer Science, or Information Technology.
Uplatz online training guarantees the participants to successfully go through the System Administrator Certification provided by Uplatz. Uplatz provides appropriate teaching and expertise training to equip the participants for implementing the learnt concepts in an organization.
Course Completion Certificate will be awarded by Uplatz upon successful completion of the System Administrator online course.
The System Administrator draws an average salary of $111.000 per year depending on their knowledge and hands-on experience.
Sysadmins have great earning potential compared to the level of study required as opposed to some of the other disciplines in IT. There is a lot of pressure in some cases, granted, but the potential for earning a decent living is one of the great things about being a sysadmin.
The demand for network and computer systems administrators is expected to grow by as much as 28 percent by 2020. Compared to other occupations, that forecasted growth is faster than average. According to the BLS data, 443,800 jobs will open up for administrators by the year 2020.
Note that salaries are generally higher at large companies rather than small ones. Your salary will also differ based on the market you work in.

Question 1. What Is Active Directory?
Answer :
Active Directory provides a centralised control for network administration and security. Server computers configured with Active Directory are known as domain controllers. Active Directory stores all information and settings for a deployment in a central database, and allows administrators to assign policies and deploy and update software.
Question 2. What Is A Domain?
Answer :
A domain is defined as a logical group of network objects (computers, users, devices) that share the same Active Directory database. A tree can have multiple domains.
Question 3. What Is Domain Controller?
Answer :
A domain controller (DC) or network domain controller is a Windows-based computer system that is used for storing user account data in a central database. It is the centrepiece of the Windows Active Directory service that authenticates users, stores user account information and enforces security policy for a Windows domain.
A domain controller allows system administrators to grant or deny users access to system resources, such as printers, documents, folders, network locations, etc., via a single username and password.
Question 4. What Is Group Policy?
Answer :
Group Policy allows you to implement specific configurations for users and computers. Group Policy settings are contained in Group Policy objects (GPOs), which are linked to the following Active Directory service containers: sites, domains, or organizational units (OUs).
Question 5. What Are Gpos (group Policy Objects)?
Answer :
A Group Policy Object (GPO) is a collection of settings that control the working environment of user accounts and computer accounts. GPOs define registry-based policies, security options, software installation and maintenance options, script options, and folder redirection options.
There are two kinds of Group Policy objects:
- Local Group Policy objects are stored on individual computers.
- Nonlocal Group Policy objects, which are stored on a domain controller, are available only in an Active Directory environment.
Question 6. What Is Ldap?
Answer :
A GLDAP (Light-Weight Directory Access Protocol) determines how an object in an Active Directory should be named. LDAP is the industry standard directory access protocol, making Active Directory widely accessible to management and query applications. Active Directory supports LDAPv2 and LDAPv3.
Question 7. Where Is The Ad Database Stored?
Answer :
The AD database is stored in C:WindowsNTDSNTDS.DIT.
Question 8. What Is The Sysvol Folder?
Answer :
The SYSVOL folder stores the server copy of the domain’s public files that must be shared for common access and replication throughout a domain.
All AD databases are stored in a SYSVOL folder and it’s only created in an NTFS partition. The Active Directory Database is stored in the %SYSTEM ROOT%NDTS folder.
Question 9. What Is Garbage Collection?
Answer :
Garbage collection is the online defragmentation of the Active Directory which happens every 12 hours.
Question 10. When Do We Use Wds?
Answer :
Windows Deployment Services is a server role used to deploy Windows operating systems remotely. WDS is mainly used for network-based OS installations to set up new computers.
Question 11. What Are Main Email Servers And Which Are Their Ports?
Answer :
Email servers can be of two types:
Incoming Mail Server (POP3, IMAP, HTTP): The incoming mail server is the server associated with an email address account. There cannot be more than one incoming mail server for an email account. In order to download your emails, you must have the correct settings configured in your email client program.
Outgoing Mail Server (SMTP): Most outgoing mail servers use SMTP (Simple Mail Transfer Protocol) for sending emails. The outgoing mail server can belong to your ISP or to the server where you setup your email account.
The main email ports are:
POP3 – port 110
IMAP – port 143
SMTP – port 25
HTTP – port 80
Secure SMTP (SSMTP) – port 465
Secure IMAP (IMAP4-SSL) – port 585
IMAP4 over SSL (IMAPS) – port 993
Secure POP3 (SSL-POP) – port 995
Question 12. What Do Forests, Trees, And Domains Mean?
Answer :
Forests, trees, and domains are the logical divisions in an Active Directory network.
A domain is defined as a logical group of network objects (computers, users, devices) that share the same active directory database.
A tree is a collection of one or more domains and domain trees in a contiguous namespace linked in a transitive trust hierarchy.
At the top of the structure is the forest. A forest is a collection of trees that share a common global catalog, directory schema, logical structure, and directory configuration. The forest represents the security boundary within which users, computers, groups, and other objects are accessible.
Question 13. Why Do We Use Dhcp?
Answer :
Dynamic Host Configuration Protocol assigns dynamic IP addresses to network devices allowing them to have a different IP address each time they are connected to the network.
Question 14. What Are Lingering Objects?
Answer :
A lingering object is a deleted AD object that still remains on the restored domain controller in its local copy of Active Directory. They can occur when changes are made to directories after system backups are created.
When restoring a backup file, Active Directory generally requires that the backup file be no more than 180 days old. This can happen if, after the backup was made, the object was deleted on another DC more than 180 days ago.
Question 15. How Can We Remove Lingering Objects?
Answer :
Windows Server 2003 and 2008 have the ability to manually remove lingering objects using the console utility command REPADMIN.EXE.
