Salesforce Certified Platform Developer II (PDII) exam is a challenging certification that measures your ability to design and develop custom solutions using Apex and Visualforce. Platform Developer II certification is intended for experienced developers who have a deep understanding of Salesforce's architecture and API capabilities. Passing the PDII Exam demonstrates your proficiency in developing complex business solutions on the Salesforce platform and can help you advance your career as a Salesforce developer.
Salesforce Platform Developer II Sample Questions (Q157-Q162):NEW QUESTION # 157
A Visualforce page loads slowly due to the large amount of data it displays. Which strategy can a developer use to improve the performance?
Answer: A
Explanation:
When a Visualforce page is slow because it attempts to load a massive dataset all at once, the bottleneck is often the time taken by the controller constructor to query and process those records before the page can even begin to render. Lazy Loading (Option B) is a strategy where the developer avoids loading all data during the initial page initialization.
Instead of querying 10,000 records in the constructor, the developer can load only the structural elements of the page first. Then, using an action method (triggered by <apex:actionFunction> or a window.onload script), the data is fetched in the background. This allows the user to see the page layout immediately while the data
"populates" shortly after. This significantly improves the Time to First Byte (TTFB) and the perceived performance of the page.
Option A (transient) is excellent for reducing the View State size and speeding up postbacks (button clicks), but it does not inherently speed up the initial load time of a large dataset. Option C (JavaScript processing) can help but doesn't solve the data retrieval bottleneck. Option D (actionPoller) is used for periodic updates and is not an efficient way to load an initial large dataset. Lazy loading ensures that the "heavy lifting" is decoupled from the initial page load, providing a more responsive experience.

NEW QUESTION # 158
The Account edit button must be overridden in an org where a subset of users still use Salesforce Classic. The org already has a Lightning Component that will do the work necessary for the override, and the client wants to be able to reuse it.
How should a developer implement this?
Answer: C

NEW QUESTION # 159
Given the following containment hierarchy:
What is the correct way to communicate the new value of a property named ''passthrough'' to my-parent-component if the property is defined within my-child-component?
Answer: D
Explanation:
To communicate a property change up a containment hierarchy in Lightning Web Components (LWC), the child component should dispatch a custom event with the detail of the change. The parent component listens for this event and handles it accordingly.
Option A is the correct method because it creates a new custom event with the detail property containing the new value of passthrough. This event is then dispatched, and the parent component can listen for this event to handle the updated value.
Options B, C, and D are incorrect because they either don't pass any data with the event or they don't use the detail object which is the standard way to pass data with custom events in LWC.

NEW QUESTION # 160
Which two best practices should the developer implement to optimize this code? Choose 2 answers
Answer: A,B
Explanation:
To optimize the code in question, it's important to follow best practices that reduce the number of SOQL queries and DML statements within loops, as these can quickly consume governor limits and lead to inefficiencies. Option C is correct because using a collection to hold records and performing a single DML operation outside of loops reduces the number of DML operations, which is a best practice for bulkifying code in Salesforce. Option D is also correct because querying records outside of a loop prevents hitting SOQL governor limits and makes the code more efficient. Options A and B are not correct in the context provided, as there isn't enough information to determine if changing the trigger context is necessary, and removing the DML statement altogether may not be feasible if the logic requires data to be persisted.

NEW QUESTION # 161
A developer is writing a Visualforce page that queries accounts in the system and presents a data table with the results. The users want to be able to filter the results based on up to five fields. However, the users want to pick the five fields to use as filter fields when they run the page. Which Apex code feature is required to facilitate this solution?
Answer: A
Explanation:
The requirement is to allow users to select which fields they want to filter by at runtime. In standard (static) SOQL, the fields in the WHERE clause must be defined at compile time (e.g., WHERE Name = :val).
Because the fields themselves are not known until the user interacts with the page, the developer cannot write a static query.
Dynamic SOQL is the required feature. It allows the developer to construct the SOQL query string as a text string at runtime, incorporating the specific field names selected by the user, and then execute that string using Database.query(queryString). This provides the flexibility to build queries on the fly based on user input. Metadata API is for configuration changes, Streaming API is for push notifications, and Variable binding (:var) is used in both static and dynamic SOQL but does not solve the issue of changing the field names themselves.
