Question: 95
A developer encounters an error that states that the Apex heap size is exceeded . Which technique may reduce heap size?
Add the transient keyword to the variable definition
Move the variable definition inside the scope of the function
Use static variables instead of instance variables
Use SOQL for loops instead of standard SOQL queries
A customer has a single Visualforce page that allows each user to input up to 1500 sales forecasts and instantly view pivoted forecast calculations. Users are complaining that the page is loading slowly, and they are seeing error messages regarding heap and view state limits.
What are three recommendations to optimize page performance? (Choose three.)

Implement pagination and reduce records per page
Create formula fields to compute pivoted forecast calculations
Use JavaScript Remoting instead of controller actions

Which two statements are true regarding these issues and resolution? Choose 2 answers
A sandbox should be created to use as a unified testing environment instead of deploying Change Sets directly to production.
Page Layouts should never be deployed via Change Sets, as this causes Workflows and Field-level Security to be reset and fields to disappear.
The administrators are deploying their own Change Sets, thus deleting each other’s fields from the objects in production.
The administrators are deploying their own Change Sets over each other, thus replacing entire Page Layouts and Workflows in Production
Question: 101
A developer is writing code that requires making callouts to an external web service . Which scenario necessitates that the callout be made in an @future method?
