1. What are the improvements in windows server 2016?
Ans: Improvements
in Windows Server 2016
Windows Server 2016 has a variety of
new features, including in below-
1. Nano Server
Microsoft announced a new installation option, Nano
Server, which offers a minimal-footprint headless version of Windows Server. It
excludes the graphical user interface.
2. Storage Services
Storage Replica replicates blocks instead of files;
files can be in use. It's not multi-master, not one-to-many and not transitive.
It periodically replicates snapshots, and the replication direction can be
changed.
3. Even more powerful Hyper-V
Hyper-V Server has allowed us to add virtual hardware
or adjust the allocated RAM to a virtual machine. However, those changes
historically required that we first power down the VM. In Windows Server 2016,
we can now "hot add" virtual hardware while VMs are online and
running. I was able to add an additional virtual network interface card (NIC)
to my running Hyper-V virtual machine.
4. PowerShell 5 is here
Windows Server 2016 comes with the Windows Management
Framework 5.1, and that includes the latest version of PowerShell. Leveraging
the .NET Framework 4.6, PowerShell 5 comes with several new features, including
new cmdlets for managing local users and groups, as well as a new Get-Computer
Info cmdlet which can dump detailed information on the system.
5. Nested Virtualization
Nested virtualization refers to the capability of a
virtual machine to itself host virtual machines. This has historically been a
"no go" in Windows Server Hyper-V, but we finally have that ability
in Windows Server 2016.Nested virtualization makes sense when a business wants
to deploy additional Hyper-V hosts and needs to minimize hardware costs
2. What is Active directory? Discuss the structure of active directory.
Ans: Active Directory is a Directory Service that is used by the Windows
Domain Networks and is developed by Microsoft. Active Directory is available in
all the Windows Server Operating Systems as it is a Service. Active Directory
is a Centralized System that manages computers and other devices on a network.
It is specially designed for distributed networking environments. Active
Directory has all the Information about all the objects - Users, Computers,
Resources like Printers, Shared Folder/ Files, in an organization's network. It
is a software to arrange, store information and provides access and permissions
based on that information. It is used to authenticate/authorize the Users,
computers, resources which is a part of a network.
Active Directory Structure has three
main tires:
Container is a special type of object used to organize Active
Directory. It does not represent anything physical, like a user or a system.
Instead, it is used to group other objects. Container objects can be nested
within other containers.
3. What is DNS? How many types of DNS zone in active directory 2016?
Describes it.
Ans:
DNS: Domain Name Servers (DNS)
are the Internet’s equivalent of a phone book. They maintain a directory of
domain names and translate them to Internet Protocol (IP) addresses. This is
necessary because, although domain names are easy for people to remember,
computers or machines, access websites based on IP addresses. DNS Port Number
is 53
Types of Zones in DNS-
There are three types
of Zone in active directory 2016.
1. Primary Zone.
2. Secondary Zone.
3. Stub Zone.
1. Primary Zone: Primary zone is the read write copy
of zone, this mean that if this zone answers the query then it is an
authoritative answer. There should be only one copy of this zone in network. In
Primary zone the file is saved as normal text file with filename(.dns)
It maintains a read only copy of zone database on another DNS server. Also, its
acts as a backup server to primary server by providing fault tolerance and load
balancing.
To understand stub zone suppose you have users in your network which are continuously accessing your business partner’s network, printer and other resources and this network is not manage by you. Also you don’t have idea about their DNS zone and other network architecture. Then it good to create a stub zone for these queries, which only contain the enough information to send your client to your partner’s DNS so that other DNS resolve your
What is DHCP? How DHCP works? Discuss the conversation of DHCP.
ANS: DHCP Stands for Dynamic Host Configuration Protocol. It’s
an application layer protocol used by hosts or computers to obtaining setup
information. Its goal is to assign unique IP Address to our hosts, it also
provides other network addresses such as the subnet mask, default gateway, and
the DNS Address.
How DHCP Works-
When we turn
our PC on and if it doesn't have any address it looks for DHCP server. The pc
will send a request to the server, called a DHCPDISCOVER request. When a DHCP
server receives a DHCPDISCOVER request from a client PC, which is an IP address
request, the DHCP server reserves an IP address for the client and makes a
lease offer by sending a DHCPOFFER message to the client. Once the offer has been made for the chosen
IP address, the device responds to the DHCP server with a DHCPREQUEST packet to
accept it. If the server decides that the device cannot have the IP address, it
will send a DHCPACK packet to the client. This packet includes the lease
duration and any other configuration information that the client might have
requested. At this point, the IP configuration process is complete.
5. What is IIS? Write down the version of IIS. 1+4=5
What is IIS: IIS stands for Internet
Information Services This is one of the most powerful web servers from
Microsoft that runs on Windows Systems to host requested Web application. You
can Host Web and FTP sites using IIS Server.IIS comes with Microsoft Windows.
The work of IIS web server is to accept requests from the remote system and
returns the proper response.IIS Server has its own process engine to handle the
requests from the client systems.
Versions of IIS Server
IIS 1.0 was initially released for
Windows NT 3.51.IIS 2.0 comes with Windows NT 4.0.
IIS 3.0 - Windows NT 4.0

Windows 10-Includes support for HTTP/2
6.
De-abbreviate
the following: 1x5=5
(a) FQDN =
fully
qualified domain name
(b) IIS =
Internet Information Services
(c)
ADDS = Active Directory Domain Services
(d) OU =
organizational unit
(e)
GPO = Group Policy
Object
7.
Fill
in the gaps:
(a) Linux is 10x times faster than windows.
(b) Windows server 2016 have 03 main product edition.
(c) Minimum 32 GB Disk Space Requirement for installing win server 2016.
(d) Active Directory Structure has 03 main tires.
