REVIEW SET 2026 ANSWERS GUARANTEED
PASS
⫸ host. Answer: Any network device with an IP address
⫸ Advantages of MLPS ( MultiProtocol Label Switch ). Answer:
•Physical layout flexibility/ provide logical links between sites so easy to
add branch office
• Prioritizing voice over data
• Redundancy in case of link failure
• One to many connections
⫸ What are three primary LAN topologies?. Answer: Bus, Ring, Star
⫸ Server. Answer: A device shares its resources with other network
devices
⫸ Star Network Topology. Answer: Star network provides ease of
scalability. It is a hub or switch device and it is common LAN network.
⫸ Advantages of Client-sever over client to client. Answer: • easier
Maintance
• greater organization
,•Tighter security
⫸ Router. Answer: It breaks up broadcast domains and are used to
connect different networks together
⫸ OSI Model. Answer: Open Systems Interconnection Model
1. Physical
2. Data link
3. Network
4. Transportation
5. Sessions
6. Presentation
7. Application
⫸ Physical Layer (Layer 1). Answer: • moves bits between devices
• Specifies voltage, wire speed, pin-out of cables
(Example: physical topology)
( takes frames from the Data Link layer and encodes the 1s and 0s into a
digital signal for transmission on the network medium. responsible for
the electrical and mechanical connections)
⫸ Data Link Layer (Layer 2). Answer: • provides access to media using
MAC address
• Combines packets into bytes and bytes into frames
,• Performs error detection, not correction
( example: LAN, framing)
responsible for the framing of data packets. protocol data units (PDU) at
this layer
⫸ Network Layer (Layer 3). Answer: • provides logical addressing,
which routers use for path determination
(Example: router)
(provides routing through an internetwork and logical addressing.)
⫸ Transport layer ( layer 4) build up a connection. Answer: •provides
reliable or unreliable delivery
• provides errors correction before retransmit
* segments and reassembles data into a data stream
( Example: TCP/ UDP Prost)
⫸ Session Layer (Layer 5). Answer: > Keeps different application's data
separate
(Dialog control)
(sets up, maintains, and terminates sessions between applications.)
⫸ Presentation Layer (Layer 6). Answer: > presents data
> handles processing such as encryption
(data encryption, compression, and translation services)
, (makes sure that data is in a readable format for the Application layer.)
⫸ Application layer(layer 7). Answer: > Provides a user interface
(responsible for finding the network resources broadcast from a server
and adding flow control and error control)
(File, print, message, database, and application services)
⫸ Devices used in an Internetwork at all seven layers. Answer: Network
management station (NMSs)
Web and application servers
Gateways (not default gatways)
Network hosts
⫸ Devices used in an Internetwork at Physical layers. Answer: Network
Interface card (NICs)
Transceivers
Repeaters
Hubs
⫸ What can a router do?. Answer: > by default, won't forward any
broadcast or multicast packets
> use the IP address( logical address) in network layer to forward the
packet to next hop
> use access lists for security control
