Salesforce Certified Development Lifecycle and Deployment Architect 認定 Development-Lifecycle-and-Deployment-Architect 試験問題 (Q133-Q138):

質問 # 133
Universal Containers has written several validation rules and workflow rules for the lead object. Which two test types should an Architect suggest to ensure that a large inbound call center does not experience platform slowdowns under high call volume for the Lead object? Choose 2 answers

A. Unit Test
B. Stress Test
C. Performance Test
D. Load Test

正解：C、D

解説：
C and D are the correct answers, as Load Test and Performance Test are the test types that should be suggested to ensure that a large inbound call center does not experience platform slowdowns under high call volume for the Lead object. A load test is a test that measures the performance and behavior of the system under a specific load, such as a large number of concurrent users or requests. A performance test is a test that measures the speed, responsiveness, and stability of the system under various conditions, such as different configurations or environments. These tests can help to identify and prevent any potential issues or bottlenecks that could affect the user experience or the system functionality. A is incorrect, as Unit Test is not a test type that should be suggested for this scenario, as it is a test that verifies the functionality and logic of a single unit of code, such as a method or a class, but not the performance or behavior of the system as a whole.
B is incorrect, as Stress Test is not a test type that should be suggested for this scenario, as it is a test that measures the performance and behavior of the system under extreme or abnormal conditions, such as exceeding the capacity or resources of the system, but not the performance or behavior of the system under normal or expected conditions. You can learn more about these tests in the Testing Strategies module on Trailhead.

質問 # 134
When replacing an old legacy system with Salesforce, which two strategies should the plan consider to mitigate the risks associated with migrating data from the legacy system to Salesforec? Choose 2 answers?

A. Identify the data relevant to the new system, including dependencies, and develop a plan/scripts for verification of data integrity.
B. Migrate users in phases based on their functions, requiring parallel use of legacy system and Salesforce for certain period of time.
C. Use a full sandbox environment for all the systems involved, a full deployment plan with test data generation scripts, and full testing including integrations.
D. Use a full sandbox environment and perform test runs of data migration scripts/processes with real data from the legacy system.

正解：B、D

質問 # 135
Universal Containers is about to begin the release of a major project. To facilitate this, they have several sandboxes to make their deployment train. These sandboxes are a mix of preview and non-preview instances.
What should the architect recommend?

A. No advice needed, mixing instance types is important for regression testing.
B. Contact support to roll back the release when Salesforce upgrades the sandboxes,
C. Refresh all non-preview sandboxes during the release preview window.
D. Refresh all non-preview sandboxes when the release management team has time.

正解：C

解説：
Explanation
Refreshing all non-preview sandboxes during the release preview window is the best way to handle the situation of having a mix of preview and non-preview instances for the release of a major project. A release preview window is a period of time before a Salesforce seasonal release, where the customers can test their applications and integrations in a sandbox that has the same version as the upcoming release. By refreshing all non-preview sandboxes during this window, the architect can ensure that all the sandboxes are aligned with the same version and avoid any conflicts or errors during the deployment. Refreshing the sandboxes when the release management team has time, mixing instance types, or contacting support to rollback the release are not good practices, as they can cause inconsistency, confusion, or disruption in the release process.

質問 # 136
Universal Containers wants to introduce data volume testing to resolve ongoing performance defects earlier in the lifecycle. Regulations prohibit the use of production data in non-production environments.
Which two options can the architect recommend?
Choose 2 answers

A. Perform data masking on full sandbox after a refresh.
B. Generate mock data that mimics production data shape and volume.
C. Request a partial Sandbox copy after the next Salesforce release.
D. Use Query Analyzer in production.

正解：A、B

解説：
Explanation
The architect should recommend generating mock data that mimics production data shape and volume, and performing data masking on full sandbox after a refresh. These options allow the team to create realistic data sets for testing without violating the regulations that prohibit the use of production data in non-production environments. Requesting a partial sandbox copy after the next Salesforce release is not a valid option, as partial sandboxes are refreshed on demand and not tied to Salesforce releases. Using Query Analyzer in production is not a way to perform data volume testing, as it only analyzes the performance of SOQL queries.

質問 # 137
A team of developers at Universal Containers has developed Apex Triggers and Apex Classes in a sandbox. The team has also written test classes to unit test these triggers and classes. When executed in the sandbox, all the test methods pass and all the classes meet the minimum code coverage requirement. But when they tried deploying these components to production, a few of these test methods failed What should an architect recommend?

A. Set SeeAllData to True to use the data in production.
B. Create test data in production before deploying the test classes
C. Explicitly set SeeAllData to True and generate data in test methods.
D. Do not use SeeAllData and generate data in the test methods

正解：D

解説：
Explanation
The best practice for writing test classes is to not use SeeAllData and generate data in the test methods. This ensures that the test classes are independent of the data in the org and can run successfully in any environment.
Creating test data in production or setting SeeAllData to True can cause unexpected failures or data conflicts.
