Question

Try to make it as simple as you can. Please provide the answers with some examples as fast as you can.

1-The technology that make up the core functionality of Windows Server 2012 include Active Directory, the Microsoft Server Manager, DHCP and IIS. Explain, in your own words, the nature and function of these technologies.

Answer:

2-Windows Server Core is a new installation option in Standard, Enterprise, and Datacenter editions. The traditional Windows GUI is not available in Server Core. Initial configuration tasks, such as changing the server name and setting IP address information, must be done from command line. What is the command ? and What are the advantages of using Windows Server Core?

3-What role does DNS play in relation to Active Directory (AD)?

4-Briefly explain, in your own words, the nature and function of a domain, tree and forest in windows networking.

5-What term is used for transferring Active Directory information among domain controllers? Explain.

Answer 1

1)This section contains information to design, deploy, manage, and troubleshoot technologies in Windows Server 2012 R2 and Windows Server 2012.

Active Directory Certificate Services Overview

This content provides an overview of Active Directory Certificate Services (AD CS) in Windows Server 2012. AD CS is the server role that allows you to build a public key infrastructure (PKI) and provide public key cryptography, digital certificates, and digital signature capabilities for your organization.

By using the Active Directory Domain Services (AD DS) server role, you can create a scalable, secure, and manageable infrastructure for user and resource management, and provide support for directory-enabled applications such as Microsoft Exchange Server.

2) Greater stability: Because a Server Core installation has fewer running processes and services than a Full installation, the overall stability of Server Core is greater. Fewer things can go wrong, and fewer settings can be configured incorrectly.

• Simplified management:Because there are fewer things to manage on a Server Core installation, it's easier to configure and support a Server Core installation than a Full one—once you get the hang of it.
• Reduced maintenance:Because Server Core has fewer binaries than a Full installation, there's less to maintain.
• Reduced memory and disk requirements:A Server Core installation on x86 architecture, with no roles or optional components installed and running at idle, has a memory footprint of about 180 megabytes (MB), compared to about 310 MB for a similarly equipped Full installation of the same edition.
• Disk space needs differ even more—a base Server Core installation needs only about 1.6 gigabytes (GB) of disk space compared to 7.6 GB for an equivalent Full installation.
• Reduced attack surface:Because Server Core has fewer system services running on it than Full installation does, there's less attack surface (that is, fewer possible vectors for malicious attacks on the server). This means that a Server Core installation is more secure than a similarly configured Full installation.
• 3)Active Directory Domain Services (AD DS) uses Domain Name System (DNS) name resolution services to make it possible for clients to locate domain controllers and for the domain controllers that host the directory service to communicate with each other.
• 4) The forest-and-tree model is a logical structure for interconnecting multiple network domains in Windows 2000 and later operating systems. A tree is a set of domains sharing a common network configuration, schema and global catalog. A forest consists of one or more trees that do not form a contiguous namespace.

In the forest-and-tree model, each tree has a unique name. Forests do not have to be named. All the trees in a forest are interconnected by trust relationships that are bi-directional (they can function in either direction) and transitive (they can be cascaded one after another in chains). In a forest, the trees form a hierarchy for the purposes of the trust relationships. It is possible for a single tree to constitute a forest in this model.

The forest-and-tree model can be useful when it is necessary to operate multiple units under separate domain name system (DNS) namespaces. Each tree within a forest can be autonomous, that is, independent of the others.

5) A logically structured organization of objects, such as users, computers, groups, and printers, that are part of a network and share a common directory database. They are defined by an administrator and administered as a unit with common rules and procedures
