問題 #152
You have an Azure Cosmos DB for NoSQL account that has multiple write regions.
You need to receive an alert when requests that target the database exceed the available request units per second (RU/s).
Which Azure Monitor signal should you use?
答案：B
解題說明：
The recommended signal in Azure Monitor is Provisioned Throughput.
To receive an alert when requests target the database and exceed the available request units per second (RU/s), the Provisioned Throughput metric is used to track the number of request units (RUs) assigned to your resources.
Signal Selection Explained
When requests exceed the provisioned RU/s, Azure Cosmos DB returns a 429 (Too Many Requests) status code. Monitoring throughput helps you proactively manage capacity and costs.
Provisioned Throughput: This metric monitors the RU/s currently configured for a container or database. Using this signal allows you to set alert thresholds based on the maximum RUs your account can handle.
Total Requests (Alternative): While not one of the options, a common way to alert on throttling is to use the Total Requests metric and filter by the 429 status code.
Incorrect:
[Not A]
Document Count tracks the number of items stored; it does not reflect request traffic or RU usage.
[Not B]
Metadata Requests monitors operations like creating or listing containers, which are separate from standard data requests.
[Not D]
Region Removed is a control-plane event related to high availability and global distribution, not throughput consumption.

問題 #153
You have three containers in an Azure Cosmos DB Core (SQL) API account as shown in the following table.
You have the following Azure functions:
A function named Fn1 that reads the change feed of cn1
A function named Fn2 that reads the change feed of cn2
A function named Fn3 that reads the change feed of cn3
You perform the following actions:
Delete an item named item1 from cn1.
Update an item named item2 in cn2.
For an item named item3 in cn3, update the item time to live to 3,600 seconds.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
NOTE: Each correct selection is worth one point.
答案：

問題 #154
You have an Azure Cosmos DB for NoSQL account.
The change feed is enabled on a container named invoice.
You create an Azure function that has a trigger on the change feed.
What is received by the Azure function?
答案：C
解題說明：
According to the Azure Cosmos DB documentation12, the change feed is a persistent record of changes to a container in the order they occur. The change feed outputs the sorted list of documents that were changed in the order in which they were modified.
The Azure function that has a trigger on the change feed receives all the properties of the updated items2. The change feed does not include the original items or only the changed properties. The change feed also includes some system-defined properties such as _ts (the last modified timestamp) and _lsn (the logical sequence number)3.
Therefore, the correct answer is:
A: all the properties of the updated items
問題 #155
You have the following Azure Resource Manager (ARM) template.
You plan to deploy the template in incremental mode.
For each of the following statements, select Yes if the statement is true. Otherwise, select No.
答案：
解題說明：
Explanation:
問題 #156
You have an Azure Cosmos DB for NoSQL account named account1 that has a single read-write region and one additional read region. Account1 uses the strong default consistency level.
You have an application that uses the eventual consistency level when submitting requests to account1.
How will writes from the application be handled?
答案：B
解題說明：
Overriding the default consistency level only applies to reads within the SDK client. An account configured for strong consistency by default will still write and replicate data synchronously to every region in the account. When the SDK client instance or request overrides this with Session or weaker consistency, reads will be performed using a single replica.
