SCCM Interview Questions
What is SCCM?
System Center Configuration Manager(SCCM) which is also known as ConfigMgr, is used to manage multiple systems of remote locations that use similar OS in order to provide services like software distribution, OS Deployment, Security etc.
1. What is Secondary Site?
Four Main characteristics:
– A Secondary Site does not have access to a Microsoft SQL Database
– Secondary Sites are ALWAYS a Child Site of a Primary Site and can only be administered via a Primary Site
– Secondary Sites cannot have Child Sites of their own
– Clients cannot be assigned directly to the Site
2.What is CENTRAL SITE?
A Central Site is a Configuration Manager Primary Site that resides at the top of the Configuration Manager hierarchy. All Database information rolls from the child to the parent and is collected by the Central Site’s Configuration Manager Database. The Central Site can administer any site below it in the hierarchy and can send data down to those sites as well.
3. What is PRIMARY SITE?
Four key features:
– The Site has access to a Microsoft SQL Server Database
– Can administer or be administered via the Configuration Manager Console
– It can be a child of other Primary Sites and can have Child Sites of its own
– Clients can be assigned directly to the Site
4. How do you create a package for Adobe?
the command line msiexec.exe /q ALLUSERS=2 /m MSIHPSJR /i “AcroRead.msi” TRANSFORMS=mytransform.mst
5. How do you distribute a package?
– create a package in SCCM, pointing it to the installation sources, and in the package create an install program (you may have already done this?)
– assign Distribution Points to your package, so the contents get synched.
– create a Collection containing the objects (users/computers) that are allowed to receive the package.
– create an Advertisement for the distribution, linking the package you created to the collection, decide whether the Advertisement is mandatory (installation enforced) or not (users have to go to the “Run Advertised Programs” dialog in Windows and select to install the program)
6. How SCCM download the patches?
You need to add the Software Update Point site role to the site, configure the software update point as active, configure the products, classifications, sync settings, etc. in the Software Update Point properties. THEN, you can go to the Update Repository node and run the Run Synchronization action from the central primary site. Once synchronization completes, you will see the metadata in the Configuration Manager console.
7. How do you configure the SUP?
In the Configuration Manager console, navigate to System CenterConfiguration Manager / Site Database /Site Management / <site code> – <site name> / Site Settings / Site Systems
Right-click the site system server name, and then click New Roles.
Select Software update point, and then click Next.
Specify whether the site server will use a proxy server when connecting to the software update point, and then click Next.
Select Use this server as the active software update point, and then specify the port settings configured for the WSUS Web site on this site system.
Specify the synchronization source for the active software update point using one of the following settings: like Synchronize from Microsoft Update or Synchronize from an upstream update server
Keep the default setting Do not create WSUS reporting events, and then click Next
Specify whether to synchronize software updates on a schedule by selecting Enable synchronization on a schedule
Specify the update classifications for which the software updates will be synchronized, and then click Next.
Specify the products for which the software updates will be synchronized, and then click Next.
Open SUPSetup.log in <InstallationPath>Logs to monitor the installation progress for the software update point. When the installation completes, Installation was successful is written to the log file.
Open WCM.log in <InstallationPath>Logs to verify that the connection to the WSUS server was successful.

8. How do you Backup SCCM Server?
To create a scheduled backup task, expand the Site Settings node and expand the Site Maintenance node, click on Tasks.
For Manual backup – Start SMS_SITE_BACKUP service
9. What are the client deployments methods?
Client Push Installation, Software update point based installation, Group Policy Installation, Logon Script Installation, Manual Installation, Upgrade Installation(software Distribution)
10. Can you discover clients those are in different AD forest?
Internet-based client management, which supports the following site systems installed in a separate forest to the site server:
Software update point
Fallback status point
11.What are the prerequisites for Software Update Point?
Windows Server Update Services (WSUS) 3.0, WSUS 3.0 Administration Console, Windows Update Agent (WUA) 3.0, Site server communication to the active software update point, Network Load Balancing (NLB), Background Intelligent Transfer Server (BITS) 2.5, Windows Installer
12. What is SMS Provider?
The SMS Provider is a WMI provider that allows both read and write access to the Configuration Manager 2007 site database. The Configuration Manager Console uses the SMS Provider.
The SMS Provider can be installed on the site database server computer, site server computer or another server class third computer during Configuration Manager 2007 Setup. After setup has completed, the current installed location of the SMS Provider is displayed on the site properties general tab.
13. What is ITMU?
SMS 2003 Inventory Tool for Microsoft Updates
14. What is the use of WSUS (Windows Server Update Service)?
It enables administrators to deploy the latest Microsoft product updates to computers that are running the Windows operating system.
15. What is SUP ( Software Update Point)?
This is required a component of software updates, and after it is installed, the SUP is displayed as a site system role in the Configuration Manager console. The software update point site system role must be created on a site system server that has Windows Server Update Services (WSUS) 3.0 installed.
16. What is BITS-Enabled Distribution Points?
Client computer always uses server message blocks (SMB) instead of BITS. Helps control bandwidth throttling between client computers and distribution points.BITS-enabled distribution point and is interrupted, it can resume where it left off.
17. What is Server Locator Point?
SLP is used in an SCCM hierarchy to complete client site assignment on the intranet and help clients find MP when they cannot find that information through AD Domain Services.
18. What is the Fallback status point?
Site system role that helps you manage clients and identify any client-related problems.
SMS 2003 client computers cannot use a fallback status point.
Fallback client support how many clients: 1lack
Identify clients that are unmanaged because they have problems communicating with their MP.
Here you can see that because an FSP was not defined, the state messages (100, 400) from the ccmsetup.log were not forwarded anywhere. The next set of snippets are from the ccmsetup.log where the client is passed the FSP= property during client installation.Notice that the FSP line is no longer blank and contains the FQDN of the server holding the FSP Role.
19. What is MIF?
SCCM can use MIF files to determine the success or failure of an installation.
After a program has finished executing, SCCM will look in the %windir% and %temp% directories for new MIF files (created after the time of the program execution start) and then match them on any or all of the following criteria.
20. Why MOF Files Used by Hardware Inventory?
2 MOF files used by hardware inventory processes are the Configuration.mof and SMS_def.mof MOF files. To enable Asset Intelligence, you need to open the SMS_DEF.MOF file
Unlike the configuration.mof file, the SMS_def.mof file is never directly sent to clients.
Configuration Manager 2007 clients actually compile only the policy generated by the contents of the .SMS_def.mof file defines the reporting classes used by the hardware inventory client agent.
21. What is the differences between Package Refresh & Package Update?
Package Update:- This should be used if you make any changes to the source files themselves. When you update a package, it will create a brand new, fully complete, compressed file (that’s the PCK file located in the SMSPKG folder) and also create a delta compressed package file, which only has the changes made between the old and new compressed files. The delta files are then sent to all the DP’s, and the new PCK file is then used for any new DP’s that are added to the package from then on. This also updates the source version of the package in SQL.
Package Refresh:- I normally use the refresh if either, I get any hash errors on clients trying to use the files to install software (the package has uncompressed but is corrupt) or in conjunction with the preloadpkgonsite.exe tool. No new PCK files are sent, it simply sends another PKG file, which then uses the current PCK file on the server and uncompresses the files again, overwriting the old package files.
22. Why to Extend Schema in SCCM?
Publish the ConfigMgr 2012 site information to AD, ConfigMgr 2012 can publish information to AD.
extadsch.exe tool or the ConfigMgr_ad_schema.ldf file
4 actions are required to enable Configuration Manager Clients to query Active Directory Domain Services to locate site resources
– Extend the Active Directory schema.
– Create the System Management container.
– Set security permissions on the System Management container.
– Enable Active Directory publishing for the Configuration Manager site.
23. What is Senders?
There are two types of senders Standard Sender & Courier Sender
Standard Sender(Pre-stage Content requires Courier sender):- The standard sender is installed and configured by default on all primary and secondary sites. If your site-to-site communications occur over a LAN that uses a supported protocol, you do not need to install another sender
Courier Sender:- The courier sender is installed and configured by default on all primary and secondary sites.When you have large packages that require excessive time or bandwidth to be sent over the network, this sender can be useful. You can use courier sender at the source Configuration Manager 2007 site to create a parcel (that is, a collection of files transferred from one site to another using courier sender); write the parcel to a tape, CD, or another physical medium; and then ship the tape or CD to the destination site by mail or a courier service. At the destination site, you can then use courier sender at that site to receive the parcel and import the package data into the site.
24. What are Discovery Methods?
– Active Directory System Group Discovery
– Active Directory Security Group Discovery
– Active Directory System Discovery
– Active Directory User Discovery
– Network Discovery
– Heartbeat Discovery
25. What are the Site System Roles?
Server Locator Point
Software Update Point
Fallback Status Point
PXE Service Point
State Migration Point
26. What are SCCM BITS Throttling?
Computer Client Agent Properties found within Site Management\Site\Site Settings\Client Agents
Group Policy Preferences to throttle BITS traffic
27. What are Ports used in SCCM?
Client to site system 80(HTTP)and default HTTPS port 443
Site Server to Site Server SMB 445 its bi-directional
TCP 2701 is the port that SCCM 2012 used for remote control
