You are working on a project that tracks health history information for patients across a region. The number of records handled by the system is in the millions due to the large number of patients in the region. Patient information must be accessible to doctors in offices, hospitals and urgent care facilities. The information should be presented to the requestor within three seconds of request, particularly for patients with critical allergies and preconditions.
You have been asked to write a performance test plan for this project.

Which of the following is the information you will need to deal with the most critical performance objective?

Who can access what data and how often will they do it
How is user access authenticated and authorized
Where will the data be stored and how much storage is available
What is the expected use of the data after it has been presented to the user

accessible to doctors in offices, hospitals and urgent care facilities. The information should be presented to the requestor within three seconds of request, particularly for patients with critical allergies and preconditions.
You have been asked to prepare a presentation for the business stakeholders regarding your plan for performance testing.

Which of the following is an example set of information that should be shared with these stakeholders?

Once configured, the performance test system will require data loading. Once loaded, we will next proceed to running a small set of sample scripts to verify the output. When those succeed we will proceed with the performance test script which ramps up users at a rate of 10 per minute until we reach the target number of concurrent users. This load will then be maintained for 2 hours
The performance test system will cost $240,000 which will include the hardware and setup. This system will allow us to create a test system that is representative of the production system and will allow us to simulate production-like conditions
Because the cost of a performance test system is prohibitive, we will conduct the performance testing in the production environment using live data
The product risks include data contention issues, data access issues, locking issues that will reject concurrent requests, network bandwidth constraints, data seek errors, data seek slowdowns or bottlenecks, and difficulty for the user in processing the returned data

If your performance test is testing the speed of the response of a web service, which protocol is being used?

ODBC
HTTP
REST
SMTP

If your performance test is testing the speed with which database requests are sent and received, which protocol is being used?

ODBC
HTTP
REST
SMTP

If you are testing from the UI and you need to simulate the amount of time it will take a real user to read a prompt and enter data in a field, what should you implement in your test script?

Wait time
Think time
Latency time
Reading time

What is the value of nesting transactions for performance testing?

It supports the concept of parent and child transactions
It allows the tester to measure a series of discrete transactions
It speeds the reporting time for the performance results
It bypasses the network communication time by sending the transaction directly to the server that will process it

accessible to doctors in offices, hospitals and urgent care facilities. The information should be presented to the requestor within three seconds of request, particularly for patients with critical allergies and preconditions.

Which of the following is a technical objective for performance that could be applicable to this project?

The response time must be within three seconds from the time the request is sent when there are 100 concurrent users making similar requests
The system must be able to scale to 10 million patient records with no degradation in the performance
The system must perform at or above the level of the legacy system when handling a similar load and responding to a similar request
The response time must remain the same when the disaster recovery system is in use rather than the primary system and the switchover must cause no discernable downtime
