Explanation:
In engineering, system integration is process of bringing various component subsystems together into one single system and also ensuring that these subsystems function as one system together.
In information technology, it is process of linking together various computing systems and various software applications functionally or physically, to act as coordinated whole.
System integrator integrates various discrete systems utilizing variety of techniques.

Answer:
Advantages of Wide Area Network as opposed to the Local Area Network:
Because of wide area network (WANs) connections are available from house to house, city to city, country to country. For ex: Internet.
WAN is connecting the devices with various wireless technologies such as: cell phone towers or satellites. All these are much harder to setup with LANs.
Local Area Network (LANs) connections can only operate in a local area, not bigger than a house or a floor in a office building and also you cannot buy a ethernet cable that can reach throughout entire building and Wi-Fi connection rapidly disconnected as you get further then few meters away.
Answer:
The answer is the point - to -point protocol, which allows user to set a secure VPN connection for client and server connectivity.
Explanation:
A virtual private network is a private-public network because of encryption and tunneling to ensure the integrity of the data. VPN requires a tunnel to work and encryption.
In VPNs, there are different protocols can be used, such as point- to - Point Tunneling Protocol (PPTP), IPSec, and L2TP.
Point to Point Protocol is a Microsoft protocol which allows user to set a connection and secure VPN destination. Point to point protocol is designed for client and server connectivity. It developed a connection between two computers. The data link layer that transmits over IP networks is used for point to point tunneling.
Such as option A is not correct because it is distracter and IPSecis primary tunneling protocol. It supports only IP networks. L2TP is not a VPN but extend VPN over the various network.
