Finding another job can be so cumbersome that it can turn into a job itself. Prepare well for the job interviews to get your dream job. Here's our recommendation on the important things to need to prepare for the job interview to achieve your career goals in an easy way. Wintel Administrator performs the admin related duties of Wintel. Wintel is the term used of computers with intel processor. Administrator is called as sysadmin and their work changes from company to company. Installation, support and maintaining servers are the duties. Problem solving skills are must for the admin role. Follow our Wisdomjobs page for Wintel Administrator job interview questions and answers page to get through your job interview successfully in first attempt.
Both do the same thing like forwarding the requests to appropriate name servers who are authoritative for the domains in the queries. However, there is difference in both, Stub Zone are Dynamic and Conditional forwarder are static.
Conditional Forwarding – Where you want DNS clients in separate networks to resolve each others’ names without having to query DNS servers on the Internet, such as in the case of a company merger, you should configure the DNS servers in each network to forward queries for names in the other network. DNS servers in one network will forward names for clients in the other network to a specific DNS server that will build up a large cache of information about the other network. When forwarding in this way, you create a direct point of contact between two networks’ DNS servers, reducing the need for recursion.
Stub Zone– Stub-Zones are dynamic -A stub zone is like a secondary zone in that it obtains its resource records from other name servers (one or more master name servers). A stub zone is also read-only like a secondary zone, so administrators can’t manually add, remove, or modify resource records on it. But the differences end here, as stub zones are quite different from secondary zones in a couple of significant ways.First, while secondary zones contain copies of all the resource records in the corresponding zone on the master name server, stub zones contain only three kinds of resource records:
A GPO (Group Policy Object) is a collection of Group Policy settings, it consists of GPC and GPT.
GPC (Group Policy Container): Contains the information of property of GPO like Security Filtering, GPO Status, GPO GUID etc.
GPT (Group Policy Template): Contains the data of GPO in Sysvol folder that can be checked after the configuration of the GPO that what settings have been configured to the client.
A majority node set is a single quorum resource, from a server cluster perspective; however, the data is actually stored on multiple disks across the cluster. Each cluster node stores the configuration on a local disk it can have access to when it starts up. By default, the location is pointed to %systemroot%clusterResourceGUID

If the configuration of the cluster changes, that change is replicated across the different disks
NLB (Network Load Balance) is a Microsoft implementation of clustering and load balancing that is intended to provide high availability and high reliability, as well as high scalability.
Unicast is a one-to one connection between the client and the server. Unicast uses IP delivery methods such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP), which are session-based protocols. When a Windows Media Player client connects using unicast to a Windows Media server, that client has a direct relationship to the server. Each unicast client that connects to the server takes up additional bandwidth. For example, if you have 10 clients all playing 100-kilobits per second (Kbps) streams, those clients as a group are taking up 1,000 Kbps. If you have only one client playing the 100 Kbps stream, only 100 Kbps is being used.
Multicast is a true broadcast. The multicast source relies on multicast-enabled routers to forward the packets to all client subnets that have clients listening. There is no direct relationship between the clients and Windows Media server. The Windows Media server generates an .nsc (NetShow channel) file when the multicast station is first created. Typically, the .nsc file is delivered to the client from a Web server. This file contains information that the Windows Media Player needs to listen for the multicast. This is similar to tuning into a station on a radio. Each client that listens to the multicast adds no additional overhead on the server. In fact, the server sends out only one stream per multicast station. The same load is experienced on the server whether only one client or 1,000 clients are listening
Strict Replication is a mechanism developed by Microsoft developers for Active Directory Replication. If a domain controller has the Strict Replication enabled then that domain controller will not get “Lingering Objects” from a domain controller which was isolated for more than the TombStone Life Time. TSL is 180 days by default on a Forest created with Windows Server 2003 SP1. A domain controller shouldn’t be outof sync for more than this period. Lingering Objects may appear on other domain controllers if replication happens with the outdated domain controllers. These domain controllers will not replicate with the outdated domain controllers if you have set the below mentioned registry key.You must set the following registry setting on all the domain controllers to enable the Strict Replication:
Registry Entry: Strict Replication Consistency
Value: 1 (enabled), 0 (disabled)
A superscope is an administrative feature of Dynamic Host Configuration Protocol (DHCP) servers running Windows Server 2008 that you can create and manage by using the DHCP Microsoft Management Console (MMC) snap-in. By using a superscope, you can group multiple scopes as a single administrative entity. With this feature, a DHCP server can:
In multinet configurations, you can use DHCP superscopes to group and activate individual scope ranges of IP addresses used on your network. In this way, the DHCP server can activate and provide leases from more than one scope to clients on a single physical network.
To generate a complete memory dump file:
Host A records of replication partners (Domain Controllers), Srv Records to find out the Domain Controllers GUID in _msdcs zone (DC Locator)
Windows Debugger (WinDbg.exe) tool
You can use AD inbuilt features to troubleshoot group policy issue like RSOP.msc or can run RSOP by selecting users in Active Directory users and computers, gpresult -v, gpt.ini in sysvol under Group Policy GUID folder can be checked to find out the GPO settings configured.
It can be troubleshooted by repmon command that generates the error result in eventvwr. DNS can be checked between two destination. Network/Firewall issue
Here’s the brief description of Windows Server 2008 Boot process:
Firstly, schmmgmt.dll has to be registered. Then ADSI Edit tool can be used to edit schema.
Windows 2003 Boot Process:
Windows Server 2008 Boot process.
FCInfo utility or Storage Explorer (windows 2008) can be used to check the same.
dnscmd command can be used for creating a Resource Record on DNS server.
Below is the command:
dnscmd [<ServerName>] /recordadd <ZoneName> <NodeName> <RRType> <RRData>
Name servers in delegations are identified by name, rather than by IP address. This means that a resolving name server must issue another DNS request to find out the IP address of the server to which it has been referred. If the name given in the delegation is a subdomain of the domain for which the delegation is being provided, there is a circular dependency. In this case the name server providing the delegation must also provide one or more IP addresses for the authoritative name server mentioned in the delegation. This information is called glue. The delegating name server provides this glue in the form of records in the additional section of the DNS response, and provides the delegation in the answer section of the response.
For example, if the authoritative name server for example.org is ns1.example.org, a computer trying to resolve www.example.org first resolves ns1.example.org. Since ns1 is contained in example.org, this requires resolving example.org first, which presents a circular dependency. To break the dependency, the name server for the top level domain org includes glue along with the delegation for example.org. The glue records are address records that provide IP addresses for ns1.example.org. The resolver uses one or more of these IP addresses to query one of the domain’s authoritative servers, which allows it to complete the DNS query.
Group Policy applies to the user or computer in a manner that depends on where both the user and the computer objects are located in Active Directory. However, in some cases, users may need policy applied to them based on the location of the computer object alone. You can use the Group Policy loopback feature to apply Group Policy Objects (GPOs) that depend only on which computer the user logs on to.
