Answer 1

6. Disadvantages of static IP Address

The Static IP address is assigned to a partilcular host for a particuar network session . So there needs to be a maintainence of Routing Table at the BOOTP server for every Host in the network.

Also if any of the host becomes inactive for long the Static address assigned to it cannot be reused.

Disadvantages of dynamic IP Address

The dynamic IP address requires more computational tasks because there is a certain lifetime of the IP address assigned to the host and the host has to again request to keep that IP address once the lifetime is over. Overhead for the DHCP server is low but more computing is required.

7.The Global catalog performs two main tasks

The first is providing data that permits network logon and secondly it makes the searching of objects easy without the use of domain name. It is maintained by AD DS replication system.

8.TCP/IP protocols are the network protocols that perform crucial tasks among connection establishement,data transfer,connection termination,packet transfer,error control,congestion control,retransmission in computer network.

The CommandLine Utility to check configuration of TCP/IP is ipconfig which displays information such as IPv4 address,IPv6 address ,the default gateway meaning router to which you are connected.

ping is the command line argument used to check self connectivity or connectivity to another host.If it shows a valid TTL(Time to live) value then it means the device NIC is working correctly and the network is established .

9. Windows Server utility that provides a common interface for tools and utilities and provides access to server roles, services, and monitoring and drive utilities is the Server Manager. It helps us to manage both local and remote server in the windows server utility.

The server utility to get the PowerShell command history is Get-History .One can also use up-down key to see previous commands.

10.The Active Directory Sites are formed by the group of different subnets within a network forming a LAN or connected through a bus.For example A company has two departments within itself and the network is divided into two subnets so the LAN that connects both subnets(i.e the company LAN) consists of computers from both subnets.Their set is called Active Directory Site.
