11. What is a Management Point (MP)?
The management point (MP) stands as the main communication channel between an SCCM site and its clients. It hands out policies, tells machines where to find software, and collects their status reports and inventory in return.
12. What is a Distribution Point (DP)?
Applications, packages, and OS images that clients download are all stored in a DP. It minimizes WAN bandwidth consumption by geographically locating content closer to clients.
13. What is the Content Library?
On every DP sits the Content Library, a single-instance store that keeps SCCM updates in one tidy, space-efficient place.
14. What is an Application Detection Method?
This technique determines whether the client already has the same version of the app installed before installing a new one. This prevents duplicate installations and maintains the integrity of compliance reports.
15. What is the role of the SMS Provider?
The SMS Provider is a WMI provider enabling the SCCM console and third-party applications to send queries to the SCCM database for management, reporting, and automation.
16. What is the purpose of a Fallback Status Point?
Fallback Status Point is utilized to collect state messages from clients who are unable to communicate with the main management point. It’s essential for the early detection of communication loss.
17. How do you deploy software using SCCM?
