Explanation:
Windows Internal Database
Windows Internal Database is a relational data store that can be used only by Windows roles and features.IPAM does not support external databases. Only a Windows Internal Database is supported.
IPAM stores 3 years of forensics data (IP address leases, host MAC addresses, user login/logoff information)
for 100,000 users in a Windows Internal Database. There is no database purge policy provided, and the
administrator must purge data manually as needed.
Incorrect:
Not A. IPAM works even if the Windows Process Activation Service is not running.
Not B. IPAM does not require the Windows Event Collector Service. It need to be running on the managed DC/
DNS/DHCP computers.
Not D. IPAM does not require the Windows Store Service. It provides infrastructure support for Windows
Store.This service is started on demand and if disabled applications bought using Windows Store will not
behave correctly.
