Answer : Forests, trees, and domains are the logical divisions in an Active Directory network. A domain is defined as a logical group of network objects computers, users, devices that share the same active directory database. A tree is a collection of one or more domains and domain trees in a contiguous namespace linked in a transitive trust hierarchy. At the top of the structure is the forest. A forest is a collection of trees that share a common global catalog, directory schema, logical structure, and directory configuration.
The forest represents the security boundary within which users, computers, groups, and other objects are accessible. Question Why Do We Use Dhcp? Answer : Dynamic Host Configuration Protocol assigns dynamic IP addresses to network devices allowing them to have a different IP address each time they are connected to the network. What Are Lingering Objects? Answer : A lingering object is a deleted AD object that still remains on the restored domain controller in its local copy of Active Directory.
They can occur when changes are made to directories after system backups are created. When restoring a backup file, Active Directory generally requires that the backup file be no more than days old. This can happen if, after the backup was made, the object was deleted on another DC more than days ago. Answer : When restoring a backup file, Active Directory generally requires that the backup file be no more than days old. If you attempt to restore a backup that is expired, you may face problems due to lingering objects. We need to use the command line to backup Active Directory. When the backup process has finished you should get a message that the backup completed successfully.
If it did not complete properly you will need to troubleshoot. Answer : Installation and replacement are some of the most frequently performed operations with hardware. Sometimes a system administrator might need to rebuild a hardware component. Typical duties include engineering, support and maintenance, and research for the purpose of innovation and upgrading. Answer : System administrators are experts at handling hardware and software. They are quick with both their hands and their head. They can work alone, but they know when and how to communicate with others, whether to report problems, learn information needed to fix problems, or instruct employees regarding technical issues.
Answer : Analytical thinking and problem solving is crucial to be able to analyze software or hardware malfunction. They are also necessary to be able to improve or upgrade systems so that they suit company needs. Assertiveness also plays a role because administrators have to make decisions. They decide on solutions, security measures, and things like system upgrades. Answer : Administrators are typically called in to offer technical support for teams working on a project.
Support might mean technical troubleshooting or the development and explanation of technological strategy with regards to the project goals and means. It offers features like security permissions to limit other users' access to folders , quotas so one user can't fill up the disk , shadowing backing up and many other features that help Windows. What Is Voip? Answer : VOIP :Short for Voice Over Internet Protocol, a category of hardware and software that enables people to use the Internet as the transmission medium for telephone calls by sending voice data in packets using IP rather than by traditional circuit transmissions.
Answer : Just start the domain controller in Directory Services Restore Mode and perform system state restore from backup Question Authoritative Restore Of Active Directory? Answer : An authoritative restore is next step of the non-authoritative restore process. We have do non-authoritative restore before you can perform an authoritative restore. The main difference is that an authoritative restore has the ability to increment the version number of the attributes of all objects or an individual object in an entire directory, this will make it authoritative restore an object in the directory.
In a non-authoritative restore, after a domain controller is back online, it will contact its replication partners to determine any changes since the time of the last backup. However the version number of the object attributes that you want to be authoritative will be higher than the existing version numbers of the attribute, the object on the restored domain controller will appear to be more recent and therefore, restored object will be replicated to other domain controllers in the Domain.
Question Answer : You can authoritatively restore only objects from configuration and domain partition. Authoritative restores of schema-naming contexts are not supported. What Are Group Policies? Answer : Group policies specify how programs, network resources, and the operating system work for users and computers in an organization. They are collections of user and computer configuration settings that are applied on the users and computers not on groups. For better administration of group policies in the Windows environment, the group policy objects GPOs are used. What Is Gpo? Answer : Group policy object GPO is a collection of group policy settings.
It can be created using a Windows utility known as the Group Policy snap-in. GPO affects the user and computer accounts located in sites, domains, and organizational units OUs. The local GPO affects only the computer on which it is stored. By default, only Security Settings nodes are configured. The rest of the settings are either disabled or not enabled. What Is Non-local Policy? The non-local GPOs must be linked to a site, domain, or organizational unit OU to apply group policies to the user or computer objects. Multiple GPOs.
Ans: The active Directory means a service that identifies and handles resources, making them visible for different groups or members that are authorized. It has the role of an object store. The Active directory sees as objects workstations, people, servers devices or documents and they all have their own characteristics and access control list or ACL. The server knows nothing about the personal computers until they make a request for information. Usually the most common information sent is IP address and DHCP is used to make a large network administration easier. The leases come from multiple scopes. These types of networks are also named multinets. Ans: Switching or transferring roles in an Active Directory can be made with the use of Ntdsutil.
It also resolves names for DNS namespaces, thing required when names must be resolved from two different DNS namespaces. Ans: Active Directory backup is made using NTbackup utility. The backup is made once with the system state and they are restored also together because they depend on each other. The system state has different components like: a The registry b Boot files or startup files files required by the operating system to start. Ans: Yes and I can explain how. Ans: There is one difference between these two: the forward lookup means name to IP and reverse lookup means IP to name. Ans: This is a responsibility that any system administrator must have assume as a basic skill. Of course there are many types of backup that can be made but all must be known for a successful career. When the system starts an IP is assigned automatically. The DHCP server has port number 68, while the client has Market research is the key to an up-to —date work. Ans: Yes it is as long as we use a public IP address.
The gateway is required as a router or firewall when using an intranet address. Ans: To do this we must open the DNS then we must select the abc. Ans: Including policies for personal and public lockout, the changes apply immediately. Ans: Files are deleted constantly by end users but the backup can restore them.
Ans: We can find: a the abstract class which can be made to look like a template and create other templates, no matter if they are abstract, auxiliary or structural. They are the only ones that can make Active Directory objects. Ans: Certain companies that have different bases require different trees and separate namespaces. And unique names sometimes give birth to different identities of DNS. Also companies are sometimes acquired and get under other influences but the continuity must be preserved for the names. Ans: I have ten years of experience in this field, I was passionate about computers since childhood and I installed many operating systems at home and inside organizations including these versions of windows: 95, 98, 98 SE, NT, Millenium, , Server, XP, Seven, Vista.
I also managed these systems and performed maintenance, I worked with different applications from the windows environment. Ans: In this situation the application has to be started in the compatibility mode with a previously windows operating system. This is made by right clicking the application icon and choosing another Windows from the compatibility menu. Ans: Repadmin. This tool is used by administrators to see the replication topology from the perspective of every domain controller. The active Directory forest can also be supervised by Repadmin. It has all the advantages for server usage. Windows is a little more professional than XP, but they are both coming with different versions for every user taste. The Home version of XP comes with minimal features because the target clients are beginners. Ans: The code loading runtime of Unix is different from the one that Windows has. We must become aware of how the system exactly works before we make a dynamically loading module.
Unix has the shared objects with the. These function names become the references of those functions in the memory of the program when the file is combined with the program. In Windows the. Unix has just one type of library file, with the. When the link is created for a shared object file the definition of the identifier may not be found, so the object code from the library will be included. Chandanakatta Author Hey there!

You're able to telnet to the port, so how do you resolve the issue? Technical skills matter a lot in systems administrator jobs. Thus, many of your interview questions should deal with assessing candidates' hard skills, and this question covers several areas of required knowledge. Look for: Identifying the problem instead of just telling hardware techs something is wrong Ability to troubleshoot Curiosity to figure out the "why" Example: "Assuming the web page is up, I would investigate what could be wrong with the monitor.
It could be a system overload or flapping, among other issues. Identifying the problem helps me prevent it in the future. What would you do? It is important for systems administrators to be unafraid of failure and experimentation. In fact, it can be rare for a first attempt at fixing a problem to succeed, and your candidates should have logical strategies for coming up with solutions. Look for: A real strategy instead of trying things randomly Recognition that multiple attempts are often necessary A walk through the process Example: "I've learned from experience that a first attempt doesn't always work.

Here's something that happened at my previous job This question lends insight into candidates' self-awareness skills as well as whether their values match those of your business. Look for: Answers that match areas of emphasis in your job description At least one soft skill Attributes that fit your company culture Example: "I'm analytical and curious.
I always dig to find out why a problem occurred. Otherwise, it is liable to happen again and hurt the business. I am also a great communicator, able to share my insight with anyone in jargon-free language. This question gets to candidates' technical knowledge. DC means domain controller, and your candidates should know what it is. Look for: Use of lingo or jargon A mention of lingering objects Knowledge of days Example: "If you back up a DC seven months old, you could encounter lingering objects that lead to inconsistent data. Backup files, as a general rule, shouldn't be over days old. Systems administrators can have a tremendous range of experiences and certifications, so it's important to hire one who can do the specific job your business needs. Look for: Qualifications that match what you're looking for An explanation of how the candidate compensates for any gaps work experience in lieu of schooling, for example Specific certifications Example: "I earned a bachelor's degree in computer science four years ago.
I've developed a reputation for identifying problematic machines early on, and I enjoy customer service and software programs such as Adobe Acrobat. Many systems administrator jobs require interaction with users and knowledge of remote techniques and ticketing systems. This question ensures that the candidate will be able to do the customer service you require. Look for: Ability to help and please clients Specific examples of accomplishments Recognition of the value of a good client experience Example: "I'm particularly proud of the fact that I can effectively identify a problem and the best tools to resolve it.
My clients often refer me to others and talk about how I quickly restore their functionality. Give an example of how you're a self-starter. This question is position-specific and gets to the heart of whether the candidate's personality fits the requirements. Someone who needs a lot of team support might not fare well here. Look for: An actual example from previous work A tie-in to telecommuting or field work for even more insight How the example benefited the worker, client or another party Example: "I was fortunate enough to have a mentor at my first systems administrator job.
He taught me the importance of initiative and preventing problems. So, I make it a point to touch base with clients regularly. In one of these instances last year, a check-in led to a conversation where I was able to identify the early stages of a badly written application. If not for that check-in, the problem could've gotten worse and proven extremely costly for the client.
