Question 28

You need to create a database in an Azure Cosmos DB for NoSQL account. The database will contain three containers named coll1, coll2 and coll3. The coll1 container will have unpredictable read and write volumes. The col!2 and coll3 containers will have predictable read and write volumes. The expected maximum throughput for coll1 and coll2 is 50,000 request units per second (RU/s) each.

How should you provision the collection while minimizing costs?

Options:

Create a provisioned throughput account. Set the throughput for coll1 to Manual. Set the throughput for coll2 and coll3 to Autoscale.

Create a provisioned throughput account. Set the throughput for call1 to Autoscale. Set the throughput for call2 and coll3 to Manual.

Create a serverless account.

Discussion

Answer:

Explanation:

Azure Cosmos DB offers two different capacity modes: provisioned through put and serverless 1 . Provisioned throughput mode allows you to configure a certain amount of throughput (expressed in Request Units per second or RU/s) that is provisioned on your databases and containers. You get billed for the amount of throughput you’ve provisioned, regardless of how many RUs were consumed 1 . Serverless mode allows you to run your database operations without having to configure any previously provisioned capacity. You get billed for the number of RUs that were consumed by your database operations and the storage consumed by your data 1 .

To create a database that minimizes costs, you should consider the following factors:

The read and write volumes of your containers

The predictability and variability of your traffic

The latency and throughput requirements of your application

The geo-distribution and availability needs of your data

Based on these factors, one possible option that you could choose is B. Create a provisioned throughput account. Set the throughput for coll1 to Autoscale. Set the throughput for coll2 and coll3 to Manual .

This option has the following advantages:

It allows you to handle unpredictable read and write v olumes for coll1 by using Autoscale, which automatically adjusts the provisioned throughput based on the current load 1 .

It allows you to handle predictable read and write volumes for coll2 and coll3 by using Manual, which le ts you specify a fixe d amount of provisioned throughput that meets your performance needs 1 .

It allo ws you to optimize your costs by paying only for the throughput you need for each container 1 .

It allows you to enable geo-distribution for your account if you need to r eplicate your data across multiple regions 1 .

This option also has some limitations, such as:

It may not be suitable for scenarios where all containers have intermittent or bursty traffic that is hard to forecast or has a low average-to-peak ratio 1 .

It may not be optimal for scenarios where all containers have low or sporadic traffic that does not justify provisioned capacity 1 .

It may not support availability zones or multi-master replication for your account 1 .

Depending on your specific use case and requirements, you may need to choose a different option. F or example, you could use a serverless account if all containers have low or sporadic traffic that does not require predictable performance or geo-distribution 1 . Alternatively, you could use a provisioned t hroughput account with Manual for all c ontainers if all containers have stable and consistent traffic that requires predictable performance or geo-distribution 1 .

Question 29

You have an Azure subscription that contains an Azure Cosmos DB for NoSQL account named account1.

For account 1, you plan to implement an integrated gateway that will use the D4s SKU.

You need to optimize integrated gateway performance for point reads from account1. The solution must meet the following requirements:

• For new point reads, maximize how long returned items remain in the integrated cache.

• For new and repeating point reads, maximize the cost benefits of the integrated cache.

What should you do for each requirement? To answer, select the appropriate options in the answer area.

NOTE: Each correct selection is worth one point.
