4.What operations we can perform on a disabled mailbox before it’s purged from the mailbox database?

  • Reconnect it to the same user account;
  • Connect it to a different user account that isn’t mail-enabled;
  • Restore it to a user account that has an existing mailbox;
  • Permanently delete it from the Exchange mailbox database.

10.What are the difference between Switchovers and Failovers?

  • Switchovers: Planned;
  • Failovers: Unplanned.

11.What are the 3 types of switchovers in Exchange Server?

Database switchovers:

A database switchover is the process by which an individual active database is switched over to another database copy (a passive copy), and that database copy is made the new active database copy;

Server switchovers:

A server switchover is the process by which all active databases on a DAG member are activated on one or more other DAG members;

Datacenter switchovers:

In a site resilient configuration, automatic recovery in response to a site-level failure can occur within a DAG, allowing the messaging system to remain in a functional state.

12.What are the 3 types of failovers in Exchange Server?

Database failovers:

A database failover occurs when a database copy that was active is no longer able to remain active;

Server failovers:

A server failover occurs when the DAG member is no longer able to service the MAPI network, or when the Cluster service on a DAG member is no longer able to contact the remaining DAG members;

Datacenter failovers:

Since we can failover the namespace between datacenters, all that is needed to achieve a datacenter failover is a mechanism for failover of the Mailbox role across datacenters.
