You are on a protect with an application that has been deployed to Production and is live with users. The client wishes to increase the number of active users.
You need to conduct load testing to ensure Production can handle the increased usage Review the specs for four environments in the following image.

Which environment should you use for load testing7

• A. acmeuat
• B. acmedev
• C. acme
• D. acmetest

Review the following result of an explain statement:

Which two conclusions can you draw from this?

• A. The join between the tables order_detail, order and customer needs to be tine-tuned due to indices.
• B. The join between the tables 0rder_detail and product needs to be fine-tuned due to Indices
• C. The worst join is the one between the table order_detail and order.
• D. The worst join is the one between the table order_detail and customer
• E. The request is good enough to support a high volume of data. but could demonstrate some limitations if the developer queries information related to the product

You are taking your package from the source environment and importing it into the target environment.
Review the errors encountered during inspection:
What is the first action you should take to Investigate the issue?

• A. Check whether the object (UUID ending in 18028821) is included in this package
• B. Check whether the object (UUD ending in 7t00000i4e7a) is included in this package
• C. Check whether the object (UUID ending in 18028931) is included in this package
• D. Check whether the object (UUID ending in 25606) is included in this package

You are asked to design a case management system for a client. In addition to storing some basic metadata about a case, one of the client's requirements is the ability for users to update a case. The client would like any user in their organization of 500 people to be able to make these updates. The users are all based in the company's headquarters, and there will be frequent cases where users are attempting to edit the same case. The client wants to ensure no information is lost when these edits occur and does not want the solution to burden their process administrators with any additional effort. Which data locking approach should you recommend?

• A. Design a process report and query to determine who opened the edit form first.
• B. Add an @Version annotation to the case CDT to manage the locking.
• C. Allow edits without locking the case CDI.
• D. Use the database to implement low-level pessimistic locking.
