  • Centralized Administration
  • Easier Management
  • Better Scalability
19
Q

Drawbacks of Client/Server

A
  • Cost
  • Dedicated hardware/software

20
Q

Benefits of Peer-to-Peer

A
  • low cost
  • No specialized OS
  • No dedicated resources
21
Q

Drawbacks of Peer-to-Peer

A
  • Decentralized management
  • Inefficient for large networks
  • Poor Scalability
22
Q

PAN

A

Personal Area Network
- Smallest type of wired or wireless network.
- covers about 10ft or less

23
Q

LAN

A

Local Area Network
- Connects components in a limited distance
- covers about 100m/300ft

24
Q

Wi-Fi Standard

A

IEEE 802.11

25
Q

Ethernet Standard

A

IEEE 802.3

26
Q

CAN

A

Campus Area Network
- A building-centric LAN that is spread across numerous buildings in a certain area

27
Q

MAN

A

Metropolitan Area Network
- Connects locations that are scattered across the city
- covers more/less 25mi

28
Q

What does a Physical Network Topology display?

A

represents how the devices & components are physically cabled and connected together, as well as their location.

29
Q

What does a Logical Topology Display?

A

Represents how data traffic actually flows through the network

30
Q

Point - to - Point

A

Direct Connection between 2 devices

31
Q

Ring Topology

A

Each device is connected to 2 other devices forming a circular path.

32
Q

what is FDDI?

A

Conducts data transmissions on fiber optic lines in a LAN
- covers about 125mi
- Operates on a dual ring structure for redundancy

33
Q

Bus Topology

A

All devices are connected to a single central cable (Backbone)

34
Q

Star Topology

A

Each node is connected back to a central point devices (switch).

35
Q

Hub and Spoke

A

Central node (hub) is connected to other hubs via multiple nodes (spokes)

36
Q

Mesh

A

Point to point connection between every single device on the network.

37
Q

What is Infrastructure mode?

A

most common type of wireless network that features a WAP as it’s central node.

38
Q

Ad Hoc Mode

A

Decentralized wireless network that creates peer to peer connections without a need for a router/AP.

39
Q

Wireless Mesh

A

An interconnection of different types of nodes, devices and radios

40
Q

Datacenter

A

A facility that is used to Organize, process, store and disseminate large amounts of data.

41
Q

Three-Tiered Hierarchy

A

Core
-consists of 2 or more routers
- used to combine 2 separate networks into 1

Aggregation/Distribution
- consists of layer 3 switches
- creates boundary definition through access lists & filters.

Access/edge
- connects all endpoint devices
- uses regular switches

42
Q

Collapsed Core

A

Network topology where the Core and Distribution layers are merged.

43
Q

Spine and Leaf

A

2- tiered Network topology that focuses on the communication within the datacenter itself.

  • Spine layer connects leaf layer switches in a full mesh
  • leaf layer switches connect directly to access layer devices
  • can give faster speeds and lower latency
44
Q

North- South traffic

A

Northbound traffic leaving data center
Southbound traffic entering the datacenter

45
Q

East - West traffic

A

Data moving within the Data center
