Module 2.3 Azure

What are some factors that determine which redundancy should be used?

• How the data is replicated in the primary region
• Whether your data is replicated to a second region that is geographically distant to the primary region
• Whether your application requires read access to the replicated data in the secondary region if the primary region becomes unavailable
• If the storage account is created or not

True or False: Azure Storage always stores multiple copies of your data?

• True
• False

Redundancy ensures your account meets its _______ and _______ targets despite failures

• Availability, Shareability
• Durability, Availability
• Availability, Durability
• Availability, Availability

If redundancy is in the primary region, which storage account can it be used on? (Select all that apply)

• Zone-redundant storage (ZRS)
• Geo-redundant storage
• Geo-zone redundancy storage
• Locally-redundance storage (LRS)

If a failure affects the primary region, this may result in data loss if the primary region cannot be recovered

• True
• False

True or False: in the primary region, data is always replicated 4 times

• True
• False

In Locally Redundant Storage (LRS), data is replicated _____ times within a single datacenter in the _____ region

• 4, Primary
• 2, Secondary
• 3, Secondary
• 3, Primary

Which storage service has the lowest cost?

• Zone-redundant storage (ZRS)
• Locally-redundant storage (LRS)
• Geo-zone redundancy storage
• Geo-redundancy storage

If I require high availability, which storage service should I use for the primary region?

• Geo-redundant storage
• Geo-zone redundant storage
• Locally-redundant storage (LRS)
• Zone-redundant storage (ZRS)

If I want max capacity, durability, and availability, I will use a Geo-redundant storage plan

• True
• False
