(FAQs) on System Administration and AWS Infrastructure:

What are the key responsibilities of a System Administrator?

System Administrators are responsible for maintaining, configuring, and ensuring the efficient operation of computer systems, servers, and networks. They handle tasks like server installation, patching, troubleshooting, backup management, and system optimization.

What is the difference between a system administrator and a network administrator?

A System Administrator focuses on managing servers, operating systems, and software installations, while a Network Administrator focuses on configuring, maintaining, and securing network infrastructures like routers, switches, and firewalls.

What is Linux, and how does it differ from UNIX?

Linux is an open-source, Unix-like operating system based on the Linux kernel. Unlike UNIX, Linux is freely available for anyone to use, modify, and distribute. UNIX, on the other hand, refers to a family of proprietary operating systems developed in the 1970s. Linux is known for its flexibility, security, and support from a large community

What are the common security measures implemented by a SysAdmin?

Common security practices include setting up firewalls, using encryption protocols, updating software regularly, implementing multi-factor authentication (MFA), setting up intrusion detection systems (IDS), and performing security audits.

What is virtualization, and why is it important for SysAdmins?

Virtualization allows running multiple virtual servers on a single physical machine, which optimizes resource utilization, reduces costs, and provides flexibility. It's important because it enables better system scalability, disaster recovery, and testing environments.

What is AWS?

Amazon Web Services (AWS) is a cloud computing platform that provides on-demand cloud services such as computing power (EC2), storage (S3), databases (RDS), networking, machine learning, and more.
