Module 14 - Planning for Disaster

What does AWS Storage Gateway enable you to do? (Select Three)

1. Use Sever Message Block (SMB) or NFS to connect to Amazon S3 2. Transfer backup jobs from tape or Virtual Tape Library (VTL) systems to the cloud 3. Present cloud-bases internet Small Computer Systems Interface (iSCSI) block storage volumes to on-premises applications

What is the difference between the pilot light and warm standby disaster recovery (DR) patterns? (Select TWO)

1. Warm standby has scaled-down version of all infrastructure that runs until a disaster occurs 2. Pilot light has minimal infrastructure that always runs. The rest does not run until a disaster occurs

Which service provides automatic failover between multiple endpoints in support of a geographic disaster recovery (DR) strategy?

Amazon Route 53

What does the multi-site disaster recovery (DR) pattern involve?

Automatic failover to a second fully functional, constantly operation, system that is in another site.

A company stores data in an Amazon Simple Storage Service (Amazon S3) bucket. Which solution provides the most efficient way to ensure that all new and existing objects and metadata are copied to another Region for disaster recovery (DR)?

Enable cross-region replication on the bucket and copy existing objects onto themselves.

Which statement about the backup and restore disaster recovery (DR) pattern is true?

Most cost-effective, but highest RTO

What are Recovery Point Objective (RPO) and Recovery Time Objective (RTO)?

RPO is the maximum acceptable data loss measured in time. RTO is the maximum acceptable time until recovery.

Which strategy is the most efficient for Amazon Elastic Compute Cloud (Amazon EC2) disaster recovery (DR)?

Store essential data off the instance and develop rapid rebuild processes for compute instances.

What can you do to quickly replicate or redeploy environments in a disaster?

Use AWS CloudFormation templates to deploy duplicate environments in the same Region.

A company requires a disaster recovery (DR) solution for a business-critical application that provides a Recovery Time Objective (RTO) and Recovery Point Objective (RPO) in minutes. However, they do not want to pay for more than what they need. Which DR pattern would most likely meet these requirements?

Warm Standby
