Remote replication

______________is the process of creating replicas of information

assets at remote sites

• Remote replication

• Local replication

• Both

• None

Remote replicas help organizations mitigate the risks associated with regionally driven outages resulting

from natural or human-made disasters.

• True

• False

_____________________can also be used for other business operations

• local replicas

• remote replicas

• both

• none

________________writes must be committed to the source and the target, prior to acknowledging “write complete” to the host

• synchronous remote replication

• asynchronous remote replication

• both

• none

__________________a write is committed to the source and

immediately acknowledged to the host.

• synchronous remote replication

• asynchronous remote replication

• both

• none

Which option is used for Synchronous replication

• -Host writes data to source

  -Data from source is replicated to target at remote site

  -Target acknowledges back to source

  -Source acknowledges write complete to host

• -Host writes data to source

  -Write is immediately acknowledged to host

  -Data is transmitted to the target at remote site later

  -Target acknowledges back to source

• None

Which option is used for asynchronous replication

• -Host writes data to source

  -Data from source is replicated to target at remote site

  -Target acknowledges back to source

  -Source acknowledges write complete to host

• -Host writes data to source

  -Write is immediately acknowledged to host

  -Data is transmitted to the target at remote site later

  -Target acknowledges back to source

• None

_________________uses one or more components of the host to perform and manage the replication operation

• Local replication

• remote replication

• Host-based remote replication

• none

what are the basic approaches to host-based remote replication?

• LVM-based replication

• database replication via log shipping

• Synchronous Replication Mode

• Asynchronous Replication Mode

_____________________ is performed and managed at the volume group level.

• database replication via log shipping

• LVM-based replication

• both

• none
