COC HNS EXAM:
Each computer is connected to every other computer by separate cabling and network offers superior redundancy
and reliability.

A. Star topology
B. Mesh topology
C. Ring topology
D. Bus topology

Answer: B

You have been asked to install a network that will provide the network users with the greatest amount of fault
tolerance. Which of the following network topologies would you choose?

A. Star
B. Ring
C. Bus
D. Mesh

Answer: D

▶️ hybrid topology
➡️Is the combination of two topology is known as hybrid
➡️The interconnection of two topology
➡️Example hybrid topology could be the combination of star and bus topology

✅ Server roles
➡️Printer server: is provided managed access the network printer devices
➡️ A server that control one or more printers and provide printer services to LAN users ➡️Manage printers
➡️Provide printer services to clients
✅File servers:
➡️A Server That provides centralized data storage which will be share among the LAN user
➡️A file storage devices on local area networks that accessible to all users on networks
➡️ Is manage file Is share file

Application server:
➡️server is make the server side of client .
➡️Server application is as well as the data available to client. Extensible mark up Language—XML web service web Application
➡️Application server is include-ASP Website creation ---IIS (Internet Information service) -----NET is manage Application
➡️Email server
A server that are used to manage and control email communication across the networks Email server Operates pop3---pos1 office protocol __SMTP—Simple email transfer protocol
➡️Web server:- A server that store web pages that Will be viewed using brother in the networks
➡️ Data base server:-Server that centrally store data base and provide dat a to the client Application in the LAN.
▶️ Organizational Units (OUs)
➡️Organizes objects within a domain into logical administrative groups
➡️Nesting when an OU is added within another OU (like a subdirectory).
➡️This creates a hierarchical structure Is sub directory of domains
➡️Trees
A group or hierarchy of domains created by adding child domain to a parent Is consist of groups ➡️Forests
A group or hierarchy of independent domain trees Forest functional level provides a way to enable forest-wide Active Directory features ➡️Sites
One or more connected IP subnets Usually has the same performance boundaries Contain only computer and connection objects

➡️Active directory partition
Active Directory is partitioned into four units:
➖Configuration partition
➖Domain Partition
➖Application Directory
➖Schema partition 1. schema partition
describes objects and attributes that can be created in a directory. This data is common to all domains in a forest and is replicated

✔️ Dis advantages of star
topology
📒If central device all work station are break down Need more cable than bus topology

A
48. Each computer is connected to every other computer by separate cabling and network offers superior redundancy
and reliability.

A. Star topology
B. Mesh topology
C. Ring topology
D. Bus topology

Answer: B

Which of the following topologies allow for network expansion with the least Amount of disruption for the
current network users?

A. Ring
B. Hybrid
C. Star
D. Bus

Answer: C

On a star network, each network device uses a separate cable to make a point to point connection to a centralized device
such as a hub. With such a configuration, a new device can be added to the network by attaching the new device to the
hub with its own cable. This process does not disrupt the users who are currently on the network.

What is bus topology? bus topology in bus topology are all computer are connected to the main cable called backbone. Both ends of backbone use terminator in order to prevent reflection of signal. if the terminator is missing or removed the data transmission is disrupted. All data transmission b/n nodes in the network is transmitted over this common transmission is able to be received by all nodes in the work virtually simultaneously. Terminator : is absorbing signal

Star topology ?
