SCCM / SMS Interview Questions And Answers

SCCM / SMS Interview Questions

> What is SCCM ?

System Center Configuration Manager (CM12 or CM07 or ConfigMgr or Configuration Manager), formerly Systems Management Server (SMS), is a systems management software product by Microsoft for managing large groups of Windows-based computer systems. Configuration Manager provides remote control, patch management, software distribution, operating system deployment, network access protection, and hardware and software inventory.

> What is SMS provider and what it does ?

The SMS Provider is a WMI provider that allows both read and write access to the Configuration Manager 2007 site database. The SMS Provider is used by the Configuration Manager console, Resource Explorer, tools, and custom scripts used by Configuration Manager 2007 administrators to access site information stored in the site database. The SMS Provider also helps ensure that Configuration Manager 2007 object security is enforced by only returning site information that the user account running the Configuration Manager console is authorized to view.

> What is PRIMARY SITE ?

Manages clients in well-connected networks. Four main characteristics:

- 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

> 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.

> 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

> Can you change a secondary site to a primary site?

No. A secondary site is always a secondary site. It cannot be upgraded, moved, or changed without deleting it and reinstalling it. If you delete and reinstall, you lose all secondary site data.

> 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.

> Can you distribute a package to a computer without making it a member of a collection?

No. To distribute software you must have a package, a program and an advertisement. Advertisements can only be sent to collections, not to computers. If you want to distribute a package to a single computer, you must create a collection for that computer.

> Can a site have more than one default management point?

No. You can configure more than one management points in a site, but only one of those management points can be configured as the default management point to support intranet clients in the site. If you are concerned about performance, you can configure more than one management point, configure them to be part of a Network Load Balancing (NLB) cluster, and them configure the NLB cluster as the default management point.

> Can a secondary site have child sites?

No. A secondary site cannot have a primary or secondary site reporting to it. Secondary sites are always child sites to a primary site.

> Can you install the Configuration Manager client components without discovering the computer first?

Yes. Client Push Installation is the only client installation method that requires clients to be discovered first.

> Does Configuration Manager 2007 mixed mode require a public key infrastructre (PKI)?

No. Configuration Manager 2007 native mode requires a PKI, but Configuration Manager 2007 does not. PKI authentication helps provide a greater level of security, but Configuration Manager 2007 does not help you install or configure the PKI infrastructure. If you do not already have the expertise to install and configure the PKI infrastructure, you can start with mixed mode and then change to native mode later.

> Can computers show up in the Configuration Manager console before they have the Configuration Manager client installed?

Yes. If you use a discovery method, Configuration Manager can find many resources and create data discovery records (DDRs) for them, and those DDRs are stored in the database. However, you cannot use Configuration Manager features such as software distribution, software updates management, and inventory until you install the client components.

> 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

> What are the client deployments methods ?

Client Push Installion, Software update point based installation, Group Policy Installation, Logon Script Installation, Manual Installation, Upgrade Installation(software Distribution).

> What is SUP ( Software Update Point) ?

This is required 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.

> What is ITMU ?

SMS 2003 Inventory Tool for Microsoft Updates.

> What are the prerequisite 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

> 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 SMS Provider is used by the Configuration Manager console. 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.

> Can you assign clients to a secondary site?

No.If you have a secondary site, the client must be assigned to the primary parent of the secondary site. However, Configuration Manager knows how to manage clients at the child secondary site. If there is a distribution point at the secondary site that has the content the clients need, the clients will probably get the content from the local distribution point instead of crossing the WAN link to the primary site.

> Can Configuration Manager 2007 be used to package software for distribution?

No. Configuration Manager 2007 delivers command lines to clients and can force those command lines to run with administrative rights using the Local System account. Configuration Manager 2007 command lines can be batch files, scripts, Windows Installer files with .msi extensions, executable files – any file that the operating system can run, Configuration Manager 2007 can distribute. However, Configuration Manager 2007 does not actually package any software for distribution.

> How many types of sites are there in SCCM 2007 ?

Primary Site: Manages clients in well-connected networks.

Secondary site: Controls content distribution for clients in remote locations across links that have limited network bandwidth.

Parent Site: It is a site at the top level in the hierarchy & it does not come under any other sites.

Child Site: A site which comes under a site in a structure & gets information from that site (Higher Level) known as child site.

> How many types of sites are there in SCCM 2012 ?

1. CAS (Central administration site):- The central administration site coordinates inter site data

replication across the hierarchy by using Configuration Manager Database replication. It also enables

the administration of hierarchy-wide configurations for client agents, discovery, and other operations.

Use this site for all administration and reporting for the hierarchy.

2. Primary Site: Manages clients in well-connected networks.

3. Secondary site: Controls content distribution for clients in remote locations across links that have

limited network bandwidth.

> What is Site server, Site system & Site system Roles ?

Site Server: The site server is the computer on which you install Configuration Manager 2007 or 2012, and it hosts services required for Configuration Manager.

Site System: A site system is any computer running a supported version of Microsoft Windows or a shared folder that hosts one or more site system roles.

Site System Role: A site system role is a function required to be able to use Configuration Manager 2007 or to use a feature of Configuration Manager.

> What is Difference between Native mode and Mixed mode ?

Native Mode: More secure solution than mixed mode because it provides better authentication, encryption, and signing using standard industry security protocols. Supports Internet-based client management and Can integrate with existing PKI deployment.

Mixed Mode: Does not require a PKI deployment, so it has no external dependencies. Supports clients running SMS 2003. Supports WINS for the means by which clients locate their default management point if Active Directory and DNS cannot be used.

> What are the Discovery Methods & DDR available in SCCM 2007 & 2012 ?

Discovery Data Records:-

When Discovery runs, it creates discovery data records (DDRs). The information contained in a DDR varies depending upon the discovered resource. For example, it can include the NetBIOS name of a computer, the IP address and IP subnet of a computer or device, and the computer operating system name.

The approximate size of an individual DDR is 1 KB. Discovery Methods:-

1. Active Directory System Discovery – Discovers computers from the specified locations in Active Directory Domain Services.

2. Active Directory User Discovery - Discovers user accounts from the specified locations in Active Directory Domain Services.

3. Active Directory Security Group Discovery - Discovers security groups, including local, global, and universal groups from the specified locations in Active Directory Domain Services.

4. Active Directory System Group Discovery – Discovers additional information about previously discovered computers from the specified locations in Active Directory Domain Services. This information includes the OU and group membership of the computer. Active Directory System Group Discovery does not discover information about new resources that did not previously exist in the Configuration Manager site database.

5. Heartbeat Discovery – Used by active Configuration Manager clients to update their discovery records in the database. Because it is initiated by an active client, Heartbeat Discovery does not discover new resources.

6. Network Discovery – Searches your network infrastructure for network devices that have an IP address. This allows you to discover devices that might not be found by other discovery methods, including printers, routers, and bridges.

7. Forest Discovery – SCCM 2012 has a new discovery method which discovers other forest in the network.

> What are the Boundaries in SCCM ?

Configuration Manager Boundaries are defined in the Configuration Manager console and are defined by IP subnet, Active Directory site name, IPv6 Prefix, IP ranges. Boundaries are used to assign clients to a specific Configuration Manager 2007 site and should be unique to each site. When defining site boundaries for sites, ensure that you do not define the same boundary for more than one Configuration Manager 2007 site, doing so leads to a situation called overlapping site boundaries.

> What is MP, DP, FSP, Reporting Service Point, Application Catalog web service point, Application Catalog website point ?

MP:- It is a primary point of contact between Configuration Manager Clients and the Configuration Manager Site server.

DP:- It is a point that stores packages for clients to install.

FSP:- A fallback status point helps you monitor client installation and identify the clients that are unmanaged because they cannot communicate with their management point.

Reporting Service Point:- A reporting services point integrates with SQL Server Reporting Services to create and manage reports for Configuration Manager.

Application Catalog web service point:- Application Catalog web service point provides software information to the Application Catalog website from the Software Library.

Application Catalog website point:- Application Catalog website point provides a list of available software to users.

> What is Software metering ?

Software metering in Configuration Manager allows you to monitor and collect software usage data on Configuration Manager Clients.

> What is BDP ?

Branch distribution points provide an option for efficient package distribution to a small office with limited bandwidth, Depends on a standard distribution point from which it receives its content. To function properly, a branch distribution must contact a BITS-enabled standard distribution.

> What is Internet-based client management ?

Internet-based client management allows you to manage Configuration Manager 2007 clients when they are not connected to your company network but have a standard Internet connection.

> What is inventory in SCCM ?

Inventory, gives you system information (such as available disk space, processor type, and operating system, Applications) about each computer. There are two types of inventory: 1. Software Inventory 2. Hardware Inventory

> What are the packages can distribute through ITMU or WSUS ?

All Microsoft package, hot fixes, patches & Software Updates,Service pack, Critical Updates, Update Roll ups.

> What is SMS Executive ?

It is a Executive Service that Host process for thread components. It Monitored Service Component Log file smsexec.log.

> What is Maintenance Window in SCCM ?

Maintenance windows provide administrators with a way to define a period of time that limits when changes can be made on the systems that are members of a collection. These windows restrict the running of operating system advertisements, as well as software update deployments and software distribution advertisements.

When a maintenance window is applied to the collection, configuration changes to collection member systems cannot normally be made outside of this time frame through Configuration Manager. This provides a safety net for administrators to ensure that client configuration changes only occur during periods when little or no impact to the organization will occur.

> Why do we use BITS in SCCM ?

1. with BITS, the data Transfer uses only the available bandwidth and will never choke your network while delivering something to clients or to Sites. 2. With BITS if we have a suspended data to be transferred, it will resume from the same point at which it was suspended.

> What is Content Library ?

The content library is a new concept that was introduced in System Center 2012 Configuration Manager. In a nut-shell, the content library stores all the Configuration Manager content efficiently on the disk. If the same file is part of two different packages, it stores only one copy in the content library. However, references are kept indicating that the file is part of both the packages.

> What is Wake on LAN in SCCM ?

This is the feature of SCCM by which SCCM sends wake up transmission packets to clients for a particular Deployment or a Task Sequence to run.

> What is Asset Intelligence in SCCM ?

The Asset Intelligence Configuration Manager feature allows administrators to inventory and manage software in use throughout the Configuration Manager hierarchy. Asset Intelligence enhances the inventory capabilities of Configuration Manager 2007 and Configuration Manager 2007 SP1 to help manage software in use and software license management in the enterprise. Many additional Asset Intelligence specific inventory classes improve the breadth of information gathered about hardware and software assets.

> What should you choose Primary Site vs Secondary Site vs Distribution Point ?

Primary Site: Choose a Primary Site when you want to manage Clients Directly.

Distribution point: Choose Distribution point at almost most of the time.

Secondary Site: Scenarios where:

- You want to manage the Upwards flow of Data Upwards ,

- You want to have a local SUP ( Software Update Point ) ,

- You want to have a local Management Point so that Clients Pick up policies and report to this Local MP , and your low bandwidth site has more than 400 or 500 Client Machines.

> Determine If You Need a Server Locator Point for Configuration Manager Clients ?

Server locator points are used in a Configuration Manager 2007 hierarchy to complete client site assignment on the intranet and help clients find management points when they cannot find that information through Active Directory Domain Services.

Intranet clients use Active Directory Domain Services as their pref- erred method to complete site assignment and find management points. However, clients must use a server locator point if ,

1. Active Directory schema is not extended for Configuration Manager 2007 or the site is not published to Active Directory Domain Services, or

2. if clients do not belong to the same Active Directory forest as the site server's forest.

> What is Out of Band Management ?

Out of band management in System Center Configuration Manager provides a powerful management control for computers that have the Intel vPro chip set and a version of Intel Active Management Technology (Intel AMT) that Configuration Manager supports.

Out of band management lets an administrative user connect to a computer's AMT management controller when the computer is turned off, in hibernation, or otherwise unresponsive through the operating system. In contrast, in-band management is the classic approach that Configuration Manager and its predecessors use, whereby an agent runs in the full operating system on the managed computer, and the management controller accomplishes tasks by communicating with the management agent.

Out of band management supplements in-band management. While in-band management supports a wider range of operations because its environment is the full operating system, in-band management might not be functional if the operating system is not present or is not operational. In these situations, by using the supplementary capabilities of out of band management, administrative users can manage these computers without requiring local access to the computer.

Out of band management tasks include the following:

1. Powering on one or many computers (for example, for maintenance on computers outside business

hours).

2. Powering off one or many computers (for example, the operating system stops responding).

3. Restarting a non functioning computer or booting from a locally connected device or known good boot

image file.

4. Re-imaging a computer by booting from a boot image file that is located on the network or by using a

PXE server.

5. Reconfiguring the BIOS settings on a selected computer (and bypassing the BIOS password if this is

supported by the BIOS manufacturer).

6. Booting to a command-based operating system to run commands, repair tools, or diagnostic

applications (for example, upgrading the firmware or running a disk repair tool).

7. Configuring scheduled software deployments to wake up computers before the computers are running.
