1. What is PRIMARY 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.
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
2. 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
3. What is CENTRAL SITE?
4. 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.
5. What is SMS Provider ?
WMI provider that allows both read and write access to the SCCM DB. SMS Provider computer is offline, all Configuration Manager 2007 consoles for the site will not function. MS Provider is used by the Configuration Manager console, Resource Explorer.
6. What is Server Locator Point ?
SLP are used in a 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.
7. What is 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 client’s: 1lack
Identify clients that are unmanaged because they have problems communicating with their MP.
Here you can see that because a 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.
8. 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.
9. 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.
Only the policy generated by the contents of the SMS_def.mof is actually compiled by Configuration Manager 2007 clients.SMS_def.mof file defines the reporting classes used by the hardware inventory client agent.
10. 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 (thats 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.
11. 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.
12. 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 other 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.
13. 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
14. What are the Site System Roles ?
Management Point
Server locator Point
Distribution Point
Software Update Point
Reporting Point
Fallback Status Point
PXE Service Point
State Migration Point
15. SCCM BITS Throttling ?
Computer Client Agent Properties found within Site Management\Site\Site Settings\Client Agents
Group Policy Preferences to throttle BITS traffic
13. 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.
16. SCCM Design questions ?
The following is a list of questions that should be considered as part of any SCCM Design.
15. In case of acquiring a new SCCM Infrastructure question to be probed ?
Network Design
Who owns the network?
How many users are there at each physical site?
What is the physical and logical layout of the underlying network?
What is the speed of network links between sites?
What is the bandwidth utilization of the network links?
Is a network map available showing the various sites, how the sites are interconnected and the speed of links between sites?
Will network links be upgraded if recommended by the SCCM Design? Are any ports closed on any firewalls or other network infrastructure that SCCM will need to use?
Which subnets are used?
Does each subnet relate to a single physical location or are subnets split across physical locations?
What types of traffic are carried over the network links?
Will SCCM activities be limited to certain times of the day?
Is any compression used on the network infrastructure such as routers?
Backups
Are backups performed across the network? When?
Are backups done on SCCM Primary Site? When? Software Distribution
How many applications are used at each site and what are the usage patterns for each application?
What is the estimated number of packages deployed in each month? 1 per month, 12 per year
Are there any business critical applications?
Are there any in-house developed applications?
Are all new application requests going to use SMS as the delivery mechanism once a request has been approved?
How often are applications updated?
Security
Are there any specific security requirements?
What IT Administration model is used for each site and overall?Support Model
What are the roles and responsibilities for implementation, usage and ongoing support of SCCM?
Which users/ groups will require access to SCCM and which tasks will they need to perform?
Are the any Service Level Agreements that may affect the overall design for SCCM?
Is there anyone/ a group with SQL skills already in the customer?
Is there anyone/ a group with IIS skills already in the customer?Clients
What languages are used on the machines to be managed by SCCM?
Are there any other projects currently in progress or planned that could either have an impact on SMS or be impacted by SCCM?
Are there any pre-requisites/ dependencies that may impact the SCCM project? Are there any “remote” users that dial into the network?
Are there any users that never connect to the LAN (for example mobile users that never connect via the LAN but only via Dialup or VPN)?
SMS ImplementationAre the Site servers dedicated to SCCM are shared with other functions/ applications such as acting as a Domain Controller, File and Print Server, hosting SQL, IIS, etc?
Who owns the servers that will be used in SCCM roles?
Which Client Agents are to be enabled?
What settings are going to be used for each Client Agent?
