Exam AZ-104 topic 3 question 82 discussion

B. The Cool access tier: The Cool access tier is suitable for infrequently accessed data and offers lower storage costs compared to the Hot access tier. C. Geo-redundant storage (GRS): Geo-redundant storage replicates data to a secondary Azure region, providing data redundancy and disaster recovery capabilities. E. Hierarchical namespace: The hierarchical namespace is required for Azure Data Lake Storage, as it enables the storage account to support the data lake's file system structure. So, the correct options are B, C, and E.

Answers B, C, E

To create an Azure Storage account that meets the requirements of supporting **Azure Data Lake Storage**, minimizing costs for **infrequently accessed data**, and **automatically replicating** data to a secondary Azure region, the following options should be configured: 1. **B. the Cool access tier** - The Cool tier is optimized for storing data that is infrequently accessed, which helps minimize costs. 2. **C. geo-redundant storage (GRS)** - GRS replicates data to a secondary Azure region, meeting the requirement of automatic replication to another region for disaster recovery. 3. **E. hierarchical namespace** - A hierarchical namespace is required to enable **Azure Data Lake Storage Gen2** features, which are essential for big data analytics. ### Correct answers: - **B. the Cool access tier** - **C. geo-redundant storage (GRS)** - **E. hierarchical namespace**

BCE are correct

This is the way.

ANSWER: B C E

B, C and E

I think it is BCDE. That is, I think it needs both hot and cold storage. Cold storage is indeed needed for minimising costs for infrequently access data, but you need to have a hot tier for data that is frequently used too. The requirements do not say that there is only infrequently accessed data, it only says that for such data they want to minimise the costs. There will always be some frequently used data so I believe that we need both hot and cold tier here.

Answer; B,C, E

As Sam says below. Its asking for the lowest access cost. From the Learn site: Hot tier - An online tier optimized for storing data that is accessed or modified frequently. The hot tier has the highest storage costs, but the lowest access costs.

Correct answer : B C E

To meet the given requirements for the Azure Storage account named storage1, you should configure the following options: B. The Cool access tier: The Cool access tier is suitable for infrequently accessed data, as it offers lower storage costs compared to the Hot access tier. This option helps minimize costs for infrequently accessed data. C. Geo-redundant storage (GRS): GRS provides data replication to a secondary Azure region, ensuring data durability and availability in case of a regional outage. This option automatically replicates data to a secondary Azure region. E. Hierarchical namespace: Azure Data Lake Storage requires a hierarchical namespace to support its features. By enabling the hierarchical namespace, you can use Azure Data Lake Storage capabilities with the storage account. So, the correct options to configure for storage1 are B. the Cool access tier, C. geo-redundant storage (GRS), and E. hierarchical namespace.

Correct answer : B C E

Answer should be : C. geo-redundant storage (GRS) D. the Hot access tier E. hierarchical namespace it is asking for "Minimize costs for infrequently accessed data." meaning that hot tier will have the minimum cost.Source: Hot tier - An online tier optimized for storing data that is accessed or modified frequently. The hot tier has the highest storage costs, but the lowest access costs. Cool tier - An online tier optimized for storing data that is infrequently accessed or modified. Data in the cool tier should be stored for a minimum of 30 days. The cool tier has lower storage costs and higher access costs compared to the hot tier. https://learn.microsoft.com/en-us/azure/storage/blobs/access-tiers-overview
