Hardware
Describe trouble shooting (IT Skill) - CORRECT ANSWER Detect and diagnose a
problem, then find a solution. Examples: Poor processor performance, full hard
drive, virus or other malware.
Describe knowledge of OS's (IT Skill) - CORRECT ANSWER Operating system
installation, application software installation, user account creation, system
monitoring. Examples: versions of Windows, Mac OS, Linux, Unix, etc.
Describe system level programming (IT Skill) - CORRECT ANSWER Shell scripts to
automate processes, manipulating configuration files for system services.
Examples: Bash, Csh scripts, Ruby scripts, C/C++ programs
,Describe system security (IT Skill) - CORRECT ANSWER Ensuring proper system
security is in place. Following or drafting policies for users. Monitoring for threats.
Examples: Keeping security patches up to date, configuring a system firewall,
installing anti-malware software, examining log files of evidence of breaches or
attacks.
Describe hardware (IT Skill) - CORRECT ANSWER Installing and configuring new
hardware. Troubleshooting, repairing, or replacing defective hardware. Examples:
replacing CPUs and disk drives, connecting network cables to network hubs,
switches, routers.
What are some System Administrator duties? - CORRECT ANSWER Account
management: creating new user accounts and deleting obsolete user accounts.
Password management: making sure that all users have passwords that agree
with the security policy.
File protection management: making sure that files are appropriately protected
(for instance, making sure that important documents are not writable by the
outside world) and performing timely backups of the file system
Installing and configuring new hardware and troubleshooting hardware including
the network.
Installing and configuring new software including updating new operating system
(OS) patches, and troubleshooting software.
Providing documentation, support, and training for computer users.
Performing system-level programming as necessary (usually through scripting
languages rather than writing large-scale applications or systems software).
Security: installing and maintaining a firewall, examining log files to see if there
are any odd patterns of attempted logins, and examining suspicious processes
that perhaps should not be running.
,What are some Network Administrator duties? - CORRECT ANSWER physically
laying down cable.
making connections.
working with the network hardware (for instance, routers and switches).
like the system administrator, the network administrator will edit configuration
files, install software (related to the network), and so forth.
Troubleshooting the network may combine physical troubleshooting (e.g., is a
cable bad?) and software troubleshooting.
There is also a security aspect to the computer network. Both the system
administrator and network administrator may work on system firewalls. Editing
configuration files, writing shell scripts, and installing software and patches will all
be part of a network administrators tasks.
Describe a Database Administrator's duties. - CORRECT ANSWER Like system
administrators, database administrators have a long list of important
responsibilities, but with a focus on the design, development, and support of
database management systems (DBMSs). Tasks will include installation,
maintenance, performance analysis, and troubleshooting as with the other
administrative areas. There are specific applications, performance tuning
parameters, account creation, and procedures associated with the DBMS that are
separate from those of system administrators and web administrators. The
database administrator may also be involved with the integration of data from
older systems to new ones. As many or most database systems are now available
over the Internet (or at least over local area networks), the administrator must
also ensure proper security measures for remote access.
Describe a Security Administrator's duties. - CORRECT ANSWER Must stay
informed of the many different types of attacks, such as denial of service attacks
on web servers, IP spoofing to intercept messages, and buffer overflow that
allows a hacker to invade computer memory with their own code. Although these
are all known forms of attacks, it does not necessarily mean that a system is
protected against them. And as these attacks are known, newer attacks are being
thought of. It is the responsibility of the security administrator to install,
, configure, and administer appropriate firewall security to protect the
organization's systems and to work proactively against such intrusions.
Describe a Web Administrator's (aka Webmaster) duties. - CORRECT ANSWER The
web administrator, also known as a webmaster, but more precisely referred to as
a web server administrator, is responsible for maintaining websites. This
responsibility differs from the development of websites. Specifically, the web
administrator must install, configure, maintain, secure, and troubleshoot the web
server. The web server is software that runs on one or more computers. The web
administrator may or may not be responsible for the hardware. Typically, the web
administrator is not a system administrator on that or those computers.
Therefore, the web administrator will have to work with the system administrator
on some aspects of installation and configuration. Securing the web server
becomes critical for businesses. Individuals outside and inside the organization
may have reason to access data on the web-server without authorization thus
requiring the need for securing the web server. The web administrator may be
required to set up password files and establish locations where server scripts can
be stored and tested. Security may be implemented directly through the web
server software, or added through the operating system, or some combination.
Security issues may be discovered by analyzing log files that are also used for data
mining.
What are the two most common support IT roles asides from administrators? -
CORRECT ANSWER training, and help desk. Training occurs as needed, but many
help desks are available 24/7.
What is information technology? - CORRECT ANSWER Task of gathering data and
processing it into information.
The ability to disseminate information using technology.
The technology itself that permits these tasks.
The collection of people who are in charge of maintaining the IT infrastructure
(the computers, the networks, the operating system).
