Storage redundancy (LRS, ZRS, GRS) in Azure - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to set the storage account redundancy to locally-redundant storage (LRS).

Azure

storage_account = StorageAccount(redundancy=[1])

Drag options to blanks, or click blank then click option'

Common Mistakes

Choosing GRS or ZRS which replicate data across regions or zones.

Using RA-GRS which includes read access to secondary region.

LRS keeps three copies of your data within a single data center for high durability.

Complete the code to configure zone-redundant storage (ZRS) for higher availability.

Azure

storage_account = StorageAccount(redundancy=[1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Confusing ZRS with GRS which replicates across regions.

Using LRS which only replicates within one data center.

ZRS replicates data synchronously across multiple availability zones in the same region.

Fix the error in the code to enable geo-redundant storage (GRS).

Azure

storage_account = StorageAccount(redundancy=[1])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using ZRS which only replicates within zones of one region.

Using LRS which does not replicate outside the data center.

GRS replicates data asynchronously to a secondary region for disaster recovery.

4fill in blank

hard

Fill both blanks to create a storage account with read-access geo-redundant storage (RA-GRS).

Azure

storage_account = StorageAccount(redundancy=[1], access_tier=[2])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Choosing GRS instead of RA-GRS for read access.

Selecting Cool tier which is for infrequent access.

RA-GRS allows read access to the secondary region. Hot access tier is for frequently accessed data.

5fill in blank

hard

Fill all three blanks to define a storage account with zone-redundant storage and cool access tier.

Azure

storage_account = StorageAccount(redundancy=[1], access_tier=[2], enable_https_traffic_only=[3])

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using LRS instead of ZRS for zone redundancy.

Not enabling HTTPS traffic only, which is a security best practice.

ZRS replicates across zones, Cool tier is for infrequent access, and enabling HTTPS only secures traffic.
