Advanced Ingerated System

Here is my responsibility and my experienced The development of a computer-based information system includes a system analysis phase. This helps produce the data model, a precursor to creating or enhancing a database. There are a number of different approaches to system analysis. When a computer-based information system is developed, system analysis (according to the Waterfall model) would constitute the following steps:

The development of a feasibility study: determining whether a project is economically, socially, technologically and organizationally feasible
Fact-finding measures, designed to ascertain the requirements of the system's end-users (typically involving interviews, questionnaires, or visual observations of work on the existing system)
Gauging how the end-users would operate the system (in terms of general experience in using computer hardware or software), what the system would be used for and so on

Another view outlines a phased approach to the process. This approach breaks system analysis into 5 phases:

Scope Definition: denoting an instrument for observing, viewing, or examining
Problem analysis: analyzing the problem that arises
Requirements analysis: determining the conditions that need to be met
Logical design: looking at the logical relationship among the objects
Decision analysis: making a final decision

Here is my duties of a system administrator are wide-ranging, and vary widely from one organization to another. Sysadmins are usually charged with installing, supporting, and maintaining servers or other computer systems, and planning for and responding to service outages and other problems. Other duties may include scripting or light programming, project management for systems-related projects.

I usually responsible for following things:
1. User administration (setup and maintaining account)
2. Maintaining system
3. Verify that peripherals are working properly
4. Quickly arrange repair for hardware in occasion of hardware failure
5. Monitor system performance
6. Create file systems
7. Install software
8. Create a backup and recover policy
9. Monitor network communication
10. Update system as soon as new version of OS and application software comes out
11. Implement the policies for the use of the computer system and network
12. Setup security policies for users. A sysadmin must have a strong grasp of computer security (e.g. firewalls and intrusion detection systems)
13. Documentation in form of internal wiki
14. Password and identity management

My beginning with Cisco products started 8 years ago with the Cisco 2500 routers with the WAN interface card to inter-connect several remote sites with leased lines, and backup with ISDN line, all done with static routing.
i remember i've read every page of it which was very well written and topics explained in a very simple way. I used boson software back then to practice configs and that made memorizing the CLI syntax faster. The summer of that very same year i had an internship opportunity at a VSAT service provider, where i touched the first cisco router ever. They used it as a CPE to termintate vpn tunnels at ATM machines. The field engineer supervising me was surprized how well i know the syntax and encouraged me to take the ccna exam
