Term
What is Activie Directory?
Definition
Active Directory is the directory service used in Microsoft networks. A directory service (or name service) connects network resources (such as volumes, folders, files, printers, users, groups and devices) with their respective network addresses, and provides that information to entities in the network.
Term
What does Active Directory DO?
Definition
  • Authentication — Ensuring that each security principal is who they say they are, usually by verifying credentials such as a user ID and password during a logon process.
  • Authorization — Ensuring that each security principal can use only the data and services they are permitted to access.
  • Name resolution — Enabling clients and domain controllers to locate and communicate with each other. AD DS uses DNS as its main name resolution method.
  • Centralized management — Controlling a wide variety of settings from a single location via a feature called Group Policy.
Term
What is an Active Directory Object?
Definition
  • User account
  • Computer account
  • Group
  • Printer
  • Share
Term

Organizational units (OUs)

Definition
AD objects within a domain can be grouped into logical containers called organizational units (OUs). OUs are objects too, which allows administrators to create nested OUs. All objects in any given OU must have unique names, and each object can be in only one OU at any given time.
Term
What are AD Groups?
Definition
AD groups. A group is a collection of AD objects, such as users, whose membership in the group grants them certain permissions. A given user can be (and usually is) a member of multiple groups. 
Term
What is a Domain?
Definition

Domains

 

An Active Directory domain is a logical group of objects (users, computers, OUs and so on) that is managed by the same administrative team and is usually located on the same physical network.

 

Term
What are Active Directory Tress?
Definition

Trees

 

Domains are organized into trees. An AD DS tree consists of multiple domains connected by two-way transitive trusts. Each domain in an AD DS tree shares a common schema and global catalog.

 

Term
What are Active Directory Forests?
Definition

Forests

 

The Active Directory forest is the highest level of the hierarchy. While domains represent administrative boundaries, forests are the main security boundary for AD DS; it is assumed that all domain administrators within a forest are trusted to some degree. Objects in separate forests are not able to interact with each other unless the administrators of each of those forests create a trust between them.

 

Term
What are Active Directory Physical Structure
Definition
  • Hosts — Devices connected to the domain network
  • Subnets — Network groups with a specified range of IP addresses and a network mask
  • Sites — Groups of one or more subnets used to optimize bandwidth use by the DC replication service
Term

Term
Do you know what SYSVol folder is?
Definition
System volume folder is a directory that houes a copy of domain files on the local hard drive with in a domain controller. this data is shared for purposes of replaction across domain. For example user logon scripts and users group policy.
Term
What is RAID?
Definition
RAID is an acronym for “redundant array of independent drives (or disks).” Basically, RAID lets you take several hard drives and group them as one unit. This can help you store backups of your data in case a drive fails, or improve the speed and efficiency of your drives, or both.
Term

What Is RAID 0?

Definition

Also called “disk striping,” RAID 0 is all about optimizing the speed of your hard drives. If you have at least two drives, using RAID 0 will combine them and write data on both of them simultaneously or sequentially, depending on your system. This will help with read and write speeds. However, if one drive fails, you will lose all of your data.

When you save a file, RAID 0 breaks the data into segments called striped units. Then it spreads that data across all of the drives in your array. This is called striping, and it helps you access data faster because you have multiple drives working together to read, write, and store data.

Using RAID 0 is faster than getting a large hard drive with the same capacity because you would only have one hard drive processing data instead of multiple drives in an array.

Term

What is RAID 1?

Definition

Otherwise known as “disk mirroring,” RAID 1 is all about backing up data (also known as redundancy). If you have at least two drives, using RAID 1 will duplicate your data and store a copy on each drive. This is called mirroring, and it ensures you won’t lose your files if a drive fails.

Using RAID 1 means that if one drive fails, you’ll still have a copy of all your data on the other drive. Then, you can replace the failed drive with a new one, even while the computer is still running. It will automatically create a new mirror image of all your data on the good drive. This capability in RAID arrays is called hot-swappable.

However, using RAID 1 means that you will only get half the storage capacity that you would get otherwise. This is because every time you save a file to one drive, you save a copy to a second drive.

RAID 1 is best used for storing data that you don’t want to lose, such as crucial banking data or family photos and documents.

Term
What commands would you uses to test network connectivity?
Definition
Ping and IPConfig
Term
What command would you use to show open ports?
Definition

Netstat

To check open portsopen a command prompt (or PowerShell) as administrator and run the netstat command as follows: netstat -aon The command displays lots of information. What you should pay attention to are Local Addresses that are in the LISTENING state. As you can see in the previous screenshot, In my Windows 10 computer, port 22 (SSH) is open.

Term
Explain what group policy is?
Definition
Group policy is used to control users, desktops, and computer configuration by creating defual template for specific members of the group. This makes it easier to control and process larger groups of users.
Term
Name diffferent types of email servers and what ports they use?
Definition

Term
Do you know what a Virtual Machine is?
Definition
A virtual machine (VM) is a digital version of a physical computer. Virtual machine software can run programs and operating systems, store data, connect to networks, and do other computing functions, and requires maintenance such as updates and system monitoring. 
Term
Do you know what Tatooing regestriy means?
Definition
Tattooing was the effect that you saw whenever you applied a registry policy to a computer or user and then removed that policy file. Even though the policy file was gone, those registry values that were set by the policy remained-tattooed into the registry until you explicitly removed them,

Term
Whjat are some best  practices for  performing Windows Patching. 
Definition

Downtime

Downtime is the key factor in entire patching activity. Many of us are experiencing issues while getting downtime for business.  Every organization handles it differently, based on business approval. Few of the methods which can be used mentioned below.!

 

Scheduling

As mentioned above, getting downtime is always a challenging task for all administrators. There are a couple of points, that we need to consider while preparing a schedule to line up it with agreed downtime.

 

Change Management

Change management is also one of the important factors in patching. This gives awareness about the upcoming changes in the environment and also help from an audit point of view. Every organization will have defined process based on business needs. It's recommended using Standard Change Template since patching activity is one of the mandatory activities which will be performed on a monthly basis. Using Standard Template we minimize the change initiator work of drafting the Change Description/Change Task etc.

 

Compliance and Reporting

It’s very important to carry out compliance check post completion of patching. Measuring the implanted work is always beneficial to the organization from the security audit point of view.

It’s recommended to perform patching compliance imitated post completion of patching. For example – if you have four hours of downtime, then perform the patching compliance scan on second of third hours so that you can re-patch the servers within the same downtime under approved change. If you missed checking compliance within the same downtime window, then you may need to request for new downtime for business and also need to raise a separate change ticket.

If your compliance mechanism is giving compliance data after 24/48 hours, then its recommended patching missing servers in upcoming downtime windows. Do not keep a backlog for a longer time. This impact on the overall compliance by end of month cycle.

What are the differenty Types of Windows Server Migration, Install, upgrade, or migrate to Windows Server

Definition

Clean install

Clean install is simplest way to install Win

In-place upgrade

In-place upgrade enables you to keep the same hardware and all the server roles you have set up without wiping and reinstalling the operating system, by which you go from an older operating system to a newer one, keeping your settings, server roles and features, and data intact. For example, if your server is running Windows Server 2019, you can upgrade it to Windows Server 2022. However, not every older operating system has a pathway to every newer one and some roles or features don't support this or need you to take extra steps. In-place upgrade works best in virtual machines where specific OEM hardware drivers are not needed for a successful upgrade.

For step-by-step guidance and more information on upgrading, review the Windows Server upgrade content and Upgrade and migrate roles and features in Windows Server.dows Server, where you install on a blank server or overwrite an existing operating system, but you will need to back up your data first and plan to reinstall your applications. There are a few things to be aware of, such as hardware requirements, so be sure to check the details for Windows Server.

Cluster Operating System rolling upgrade

Cluster Operating System (OS) rolling upgrade gives an administrator the ability to upgrade the operating system of the cluster nodes without stopping the Hyper-V or the Scale-Out File Server workloads. For example, if nodes in your cluster are running Windows Server 2019 you can install Windows Server 2022 on them avoiding downtime to the cluster, which would otherwise impact Service Level Agreements. This feature is discussed in more detail at Cluster OS rolling upgrade.

Migration

Migration of Windows Server is when you move one role or feature at a time from a source computer that is running Windows Server to another destination computer that is running Windows Server, either the same or a newer version. For these purposes, migration is defined as moving one role or feature and its data to a different computer, not upgrading the feature on the same computer.

License conversion

License conversion enables you to convert a particular edition of the release to another edition of the same release in a single step with a simple command and the appropriate license key for some Windows Server releases. For example, if your server is running Windows Server 2022 Standard, you can convert it to Windows Server 2022 Datacenter. Keep in mind that while you can move up from Windows Server 2022 Standard to Windows Server 2022 Datacenter, you are unable to reverse the process and go from Datacenter edition to Standard edition. In some releases of Windows Server, you can also freely convert between OEM, volume-licensed, and retail versions with the same command and the appropriate key.
