NEW QUESTION # 69
You have a database named db1 in an Azure Cosmos DB for NoSQL
You are designing an application that will use dbl.
In db1, you are creating a new container named coll1 that will store in coll1.
The following is a sample of a document that will be stored in coll1.
The application will have the following characteristics:
* New orders will be created frequently by different customers.
* Customers will often view their past order history.
You need to select the partition key value for coll1 to support the application. The solution must minimize costs.
To what should you set the partition key?
Answer: C
Explanation:
Based on the characteristics of the application and the provided document structure, the most suitable partition key value for coll1 in the given scenario would be the customerId, Option B.
The application frequently creates new orders by different customers and customers often view their past order history. Using customerId as the partition key would ensure that all orders associated with a particular customer are stored in the same partition. This enables efficient querying of past order history for a specific customer and reduces cross-partition queries, resulting in lower costs and improved performance.
a partition key is a JSON property (or path) within your documents that is used by Azure Cosmos DB to distribute data among multiple partitions 3 . A partition key should have a high cardinali ty, which means it should have many distinct values, such as hundreds or thousands 1 . A partition key should also align with the most co mmon query patterns of your application, so that you can efficiently retrieve data by using the partition key value 1 .
Based on these criteria, one possible partition key that you could use for coll1 is B. customerId .
This partition key has the following advantages:
* It has a high cardinality, as each customer will have a unique ID 3 .
* It aligns with the query patterns of the application, a s customers will often view their past order history
3 .
* It minimizes costs, as it reduces the number of cross-partition queries and optimizes the storage and throughput utilization 1 .
This partition key also has some limitations, such as:
* It may not be optimal for scenarios where orders need to be queried independently from customers or aggregated by date or other criteria 3 .
* It may result in hot partitions or throttling if som e customers create orders more frequently than others or have more data than others 1 .
* It may not support transactions a cross multiple customers, as transactions are scoped to a single logical partition 2 .
Depending on your specific use case and requirements, you may need to adjust this partition key or choose a different one. For example, you could use a synthetic partition key that conc atenates multiple properties of an item 2 , or you could use a partition key with a random or pre-calculated suffix to distribute the workload more evenly 2 .
NEW QUESTION # 70
Hotspot Question
You have an Azure subscription that contains an Azure Cosmos DB for NoSQL account. The account hosts two containers named Customers and Sale Transactions. The Customers container stores customer data.
Each customer data item includes a field named numberOfSales that must be updated when an item is added to the SaleTransactions container.
You need to ensure referential integrity between the containers. The solution must meet the following requirements:
- Detect changes to the SaleTransactions container.
- Apply a new aggregate count to the related items in the Customers
container.
What should you use to implement each requirement? To answer, select the appropriate options in the answer area.

NEW QUESTION # 71
You have an Azure Cosmos DB Core (SQL) API account named account1.
You have the Azure virtual networks and subnets shown in the following table.
The vnet1 and vnet2 networks are connected by using a virtual network peer.
The Firewall and virtual network settings for account1 are configured as shown in the exhibit.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation:
Box 1: Yes
VM1 is on vnet1.subnet1 which has the Endpoint Status enabled.
Box 2: No
Only virtual network and their subnets added to Azure Cosmos account have access. Their peered VNets cannot access the account until the subnets within peered virtual networks are added to the account.
Box 3: No
Only virtual network and their subnets added to Azure Cosmos account have access.

You configure Azure Cognitive Search to index a container in an Azure Cosmos DB Core (SQL) API account as shown in the following exhibit.
Use the drop-down menus to select the answer choice that completes each statement based on the information presented in the graphic.
NOTE: Each correct selection is worth one point.
Answer:
Explanation:
Explanation
Box 1: country
The country field is filterable.
Note: filterable: Indicates whether to enable the field to be referenced in $filter queries. Filterable differs from searchable in how strings are handled. Fields of type Edm.String or Collection(Edm.String) that are filterable do not undergo lexical analysis, so comparisons are for exact matches only.
Box 2: name
The name field is not Retrievable.
Retrievable: Indicates whether the field can be returned in a search result. Set this attribute to false if you want to use a field (for example, margin) as a filter, sorting, or scoring mechanism but do not want the field to be visible to the end user.
Note: searchable: Indicates whether the field is full-text searchable and can be referenced in search queries.
