Correct Answer: D. D. All of the mentioned
Explanation: PING (Packet Internet Groper) command is the best way to test connectivity between two nodes, whether it is Local Area Network (LAN) or Wide Area Network (WAN). Ping uses ICMP (Internet Control Message Protocol) to communicate to other devices.

Correct Answer: B. B. Nmap
Explanation: A ping sweep is a method that can establish a range of IP addresses which map to live hosts and are mostly used by network scanning tools like nmap. A ping sweep is basically a collective ping command execution on a range of IP addresses.

Correct Answer: D. D. Both ping & traceroute
Explanation: ICMP stands for Internet Control Message Protocol. ICMP operates over the IP packet to provide error reporting functionality, so in case the node is not active or there is no route, ICMP will be used to report the specific errors for Ping and Traceroute.

Correct Answer: A. A. Route
Explanation: The route command is used to view and manipulate the TCP/IP routing table in Windows OS. The manipulations done in the routing table with the help of this command will count as static routes.

Correct Answer: D. D. Traceroute
Explanation: Traceroute command is available on Linux OS to find the path i.e. the number of the routers that the packet has to go through to reach the destination. In Windows, Tracert command is used to perform the function.

Correct Answer: D. D. Trace the routers in the path to destination
Explanation: The Tracert command is available on Microsoft Windows to find the path i.e. the number of the routers that the packet has to go through to reach its destination.

Correct Answer: A. A. Domain check
Explanation: There are billions of domains available for registration on the World Wide Web, and many of them are already registered. So when one wants to register a domain, they need to check whether the domain is available through a domain check.

Correct Answer: C. C. Pathping combines the functionality of ping with that of route
Explanation: Pathping combines the functionality of ping with that of traceroute (tracert). The Ping command is used to test connectivity between two nodes and the Tracert/Traceroute command is used to find the path i.e. the number of the routers that the packet has to go through to reach its destination.

Correct Answer: A. A. Scatternet
Explanation: Piconet is the basic unit of a bluetooth system having a master node and upto seven active slave nodes. A collection of piconets is called scatternet and a slave node of a piconet may act as a master in a piconet that is part of the scatternet.
