उत्तर :
व्याख्या :
Loop back or diagnostics

प्र: What is the Classs A Private IP address space? 1394 0

उत्तर :
व्याख्या :
10.0.0.0 through 10.255.255.255

प्र: What is the Class B private IP address space? 1218 0

उत्तर :
व्याख्या :
172.16.0.0 through 172.31.255.255

प्र: What is the Class C private IP address space? 1349 0

उत्तर :
व्याख्या :
192.168.0.0 through 192.168.255.255

प्र: Differentiate the DoD and the OSI network models? 1273 0

उत्तर :
व्याख्या :
The DoD model is a condensed version of the OSI model, composed of four layers instead of seven, but is nonetheless like the OSI model in that it can be used to describe packet creation and devices and protocols can be mapped to its layers.

प्र: Describe the functions of DNS and DHCP in the network? 845 0

उत्तर :
व्याख्या :
Dynamic Host Configuration protocol (DHCP) provides network configuration information (including IP address) to hosts, eliminating the need to perform the configurations manually. Domain Name Service (DNS)resolves hostnames - both internet names such as www.routersim.com and device names such as workstation 2 to IP addresses, eliminating the need to know the IP address of a device for connection purposes.

प्र: If a host on a network has the address 172.16.45.14/30, what is the subnetwork this host belongs to? 3443 0

उत्तर : 4. "172.16.45.12"
व्याख्या :
Answer: D) 172.16.45.12 Explanation: A/30, regardless of the class of address, has a 252 in the fourth octet. This means we have a block size of 4 and our subnets are o,4,8,12,16, etc. Address 14 is obviously in the 12 subnet.

प्र: The network address of 172.16.0.0/19 provides how many subnets and hosts? 1324 0

उत्तर : 4. "8 subnets, 8190 hosts each"
व्याख्या :
Answer: D) 8 subnets, 8190 hosts each Explanation: A CIDR address of/19 is 255.255.224.0. This is a Class B address, so that is only 3 subnet bits, but it provides 13 host bits, or 8 subnets, each with 8,190 hosts.
