Which of the following were drawbacks to using the Windows failover cluster feature that was available in Windows Server $2008$ and earlier? $($Select two.$)$

answer

The shared storage was a single point of failure.

When the main server went down, devices couldn't keep their current IP configuration.

It was difficult and time consuming to configure.

Backup servers that already had a large number of addresses couldn't handle the additional load.

The servers did not share information on active leases.
