Key Concepts in Systems and Network Administration

Administrator's account

Recommended account for system or network administrators to use for all tasks.

Systems Administration

Role responsible for managing all resources in an organization's IT, encompassing various administrative tasks.

Network Administrator

Individual responsible for configuring infrastructure devices like routers, switches, and firewalls.

EIA-TIA Wiring Standards

Standards specifying maximum segment lengths for cables, such as 90 meters for UTP horizontal cables.

Telecommunication Closet

Location holding switches for distribution, following a hierarchical model, also known as MDF.

Patch cable

Cable type in EIA-TIA standards connecting end-user workstations to the network.

Entrance Facility

Point where the ISP's network meets the organization's network, managed by the Systems Administrator.

Hierarchical Network Design

Model focusing on core, distribution, and access layer implementation and deployment.

LLDP

Protocol recommended for supporting Cisco, HP, and Dell products to generate network topological maps.

Needs Analysis

Phase involving determining network usage programs and areas for system administrators.

Geographic Scope

Phase subcomponent covering network coverage and span.

Traditional Network Design

Methodology using a structured systems analysis and design process similar to software development.

Categorizing network needs

Process of identifying network requirements as mandatory, desirable, or wish-list.

Building Block Process

Concept emphasizing the cost-effectiveness of using standard components throughout a network.

Technology Design

Deliverable of the building block approach model, including developed physical network topologies.

Debug AAA Authentication

IOS command useful for troubleshooting AAA problems, providing a high-level view of the login process.

Accounting

Example of tracking user activities and resource consumption, such as user access to the domain controller.

Authorization

Restricting user access to specific resources, like end-users being restricted from the control panel.

TACACS+

Protocol separating authentication and authorization processes.

4

Number of ports used by RADIUS for AAA functions:

Authentication

Process of identifying a user to grant access to a system.

ICMP

ICMP : Ping <==> ____ : tracert

NO SHUT

____ : polling <=> interface g0/0/p0 changed to up : event-reporting

LOS

manager : putty <=> agent : ___

International Organization for Standardization

TCP/IP : Institute of Electronics and Electrical Engineers <=> OSI :_______________________

SGMP

___ : SNMP <=> IGRP : EIGRP

AD LDS

A structured information store based on the structure of AD DS.

AD DS

Allows system admin to manage essentially as many objects, users, computers, printers, shares as we can cram into it given that we have the hardware to support it in a centralized manner.

partitions

Domain directory, schema directory, application directory, configuration directory, and global catalog are all examples of ____________ in an Active Directory Domain Services.

schema

It defines an attribute list which all objects in the Active Directory Domain Services can have.

authentication

A passport is a good analogy for _____________________________.

Masquerade

In general, a ______________ is a disguise. In terms of network security matters, it is a type of attack where the intruders pretends to be an authorized user of a system.

CyberSecurity

It is the use of safeguarding your company's networks, computers and data from prohibited digital access, attack or destruction by performing different procedures, technologies and execution.

Modification

If an attackers or intruders not only accesses but meddle with an asset, the threat is a _____________________.

Network security

The role of __________________ is to protect the company's Information Technology infrastructure from all forms of cyber menaces.

Logical network topology

It demonstrates, at a higher level, how data moves within a network.

LDAP

Provides the link that applications use to communicate with other directory services or servers.

Efficiency Oriented

Throughput and utilization is an example of.

False

A non-elimination of single point of failure is one of the multi-master replication advantages.

Trust Relationships

It is a secure communication paths that allow security principals in one domain to be authenticated and accepted in other domains.

FCAPS

An FCAPS level where inventory of equipment and programs is kept and updated regularly.

fabrication

The intruder may add spurious transactions to a network communication system or add records to an existing database. This statement is best describe by the what security threats?

Distributed Management System

A set of tools used available on the Windows Server to administer and manage the entire network.

System Properties

To change the computer name of the workstations or Clients running Windows 7, you need to access the ________________ where Computer Name tab is available.

Session

Which layer establishes, maintains, and terminates communications between applications located on different devices?

Forests

It pertains to one or more domains that share a common schema, common configuration, automatic transitive trust relationships, and common global catalog.

Polling

Monitoring method where information flow is initiated from the agent to manager.

controlling complexity

A NM user requirement where there were continued growth of devices, users, applications & protocols.

Transitive Trusts

Forest-to-forest ________________ can be created between Windows Server 2003 forests only (ie not between Windows 2000 forests).
