Storage account creation in Azure - Practice Problems & Coding Challenges

Challenge - 5 Problems

Choosing the right redundancy option for Azure Storage Account

You want to create an Azure Storage Account that ensures your data is safe even if an entire Azure region fails. Which redundancy option should you choose?

A Read-access geo-redundant storage (RA-GRS)

B Geo-redundant storage (GRS)

C Zone-redundant storage (ZRS)

D Locally-redundant storage (LRS)

💡 Hint

Think about which option replicates data across regions, not just within one region.

Read-access geo-redundant storage (RA-GRS) replicates your data to a secondary region hundreds of miles away and provides read access to the secondary region, protecting against regional outages.

❓ Configuration

Correctly configuring Azure Storage Account for secure access

You want to create a Storage Account that only allows secure HTTPS connections. Which configuration setting must you enable?

A Enable 'Large file shares'

B Enable 'Allow Blob public access'

C Disable 'Firewall and virtual networks'

D Set 'Secure transfer required' to true

💡 Hint

Focus on settings that enforce encrypted connections.

Setting 'Secure transfer required' to true forces all requests to use HTTPS, ensuring secure data transfer.

Impact of Storage Account kind on service features

You create a Storage Account with kind set to 'BlobStorage'. Which feature will NOT be available in this account?

A File shares

B Access tiers (Hot, Cool)

C Blob versioning

D Blob lifecycle management

💡 Hint

Consider which storage services are supported by the 'BlobStorage' kind.

'BlobStorage' accounts support blob services only and do not support file shares.

❓ security

Effect of network rules on Storage Account access

You configure your Storage Account to allow access only from selected virtual networks. What will happen if a request comes from a public IP not in the allowed list?

A Request is allowed if it has a valid access key

B Request is denied regardless of authentication

C Request is allowed if it uses HTTPS

D Request is redirected to the nearest allowed network

💡 Hint

Think about how network restrictions affect all incoming traffic.

When network rules restrict access, any request from outside allowed networks is denied even if authentication is valid.

Optimizing Storage Account performance for high throughput workloads

You need to create a Storage Account optimized for high throughput and low latency for large-scale analytics. Which combination of settings is best?

A Standard performance, General-purpose v2, Locally-redundant storage (LRS)

B Standard performance, BlobStorage kind, Geo-redundant storage (GRS)

C Premium performance, BlockBlobStorage kind, Zone-redundant storage (ZRS)

D Premium performance, FileStorage kind, Read-access geo-redundant storage (RA-GRS)

💡 Hint

Consider which performance tier and account kind support high throughput for blobs.

Premium performance with BlockBlobStorage kind and ZRS provides low latency and high throughput optimized for large-scale blob analytics.
