Microsoft MTA Networking Fundamentals (98-366 Deutsch Version) - 98-366 Deutsch Exam Practice Test

Explanation:
* Star
In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch.
* Ring
Each device present in Ring Topology is incorporated with a REPEATER.
* Mesh
Fully connected mesh topology:

A fully connected network is a communication network in which each of the nodes is connected to each other.
* Star
In star topology, every node (computer workstation or any other peripheral) is connected to a central node called a hub or switch.
* mesh (full)
The major disadvantage is that the number of connections grows quadratically with the number of nodes,as per the formula: c=n(n-1)/2
* Ring
Ring Topology: In this type of Topology, data is passed from one node to another in a series.
Here each device has dedicated Point-to-Point connection, with only two devices present on either side of it.

Explanation:
NO. No. YES.
In computer security, a DMZ or demilitarized zone (sometimes referred to as a perimeter network) is a physical or logical subnetwork that contains and exposes an organization's external-facing services to a larger and untrusted network, usually the Internet. The purpose of a DMZ is to add an additional layer of security to an organization's local area network (LAN); an external network node only has direct access to equipment in the DMZ, rather than any other part of the network.

Explanation:
* (1) Application layer protocols include:
Remote login to hosts: Telnet
File transfer: File Transfer Protocol (FTP), Trivial File Transfer Protocol (TFTP) Electronic mail transport: Simple Mail Transfer Protocol (SMTP) NTP, Network Time Protocol
* (2) Session Layer
Session-layer services are commonly used in application environments that make use of remote procedure calls (RPCs).
NetBios is also a session layer protocol.
* (3) Network Layer
The network layer is responsible for packet forwarding including routing through intermediate routers. Network Layer protocols include IPX (Internetwork Packet Exchange). / X.25 is one of the oldest packet-switched services available. It was developed before the OSI Reference Model.
The protocol suite is designed as three conceptual layers, which correspond closely to the lower three layers of the seven-layer OSI model. It also supports functionality not found in the OSI network layer. / NetWare Link Services Protocol (NLSP) is a routing protocol for Internetwork Packet Exchange (IPX).
* (4) Data link layer
WAPs (Wireless access points) and wwitches operate on the data link layer.
* (5) Network layer
Network layer protocols include ICMP (Internet Control Message Protocol), RIP (Routing Information Protocol), and ARP (Address Resolution Protocol).
* (6) Data link layer
the data link layer is responsible for media access control, flow control and error checking.
Bridges and network cards are on the data link layer.

Explanation:
T3 lines are a common aggregation of 28 T1 circuits that yields 44.736 Mbps total network bandwidth . Besides being used for long-distance traffic, T3 lines are also often used to build the core of a business network at its headquarters.
