Salesforce Certified Platform Developer I Sample Questions (Q164-Q169):

NEW QUESTION # 164
Given the following Anonymous block:

What should a developer consider for an environment that has over 10,000 Case records?

A. The transaction will fail due to exceeding the governor limit.
B. The try-catch block will handle exceptions thrown by governor limits.
C. The transaction will succeed and changes will be committed.
D. The try-catch block will handle any DML exceptions thrown,

Answer: A

Explanation:
The code provided processes allCaserecords in a single transaction. Since it attempts to process over 10,000 records, it exceeds the Salesforce governor limit of 50,000 DML rows per transaction, causing the transaction to fail.
Governor Limits on DML Rows (C):Salesforce enforces a governor limit of 50,000 rows for DML operations per transaction. In this case, if theSELECTquery retrieves over 50,000 records, theDatabase.updatecall will hit this limit and throw aSystem.LimitException.
Reference:Apex Governor Limits
Why the Try-Catch Block Fails to Handle Limits (B & D):Governor limit exceptions (System.
LimitException) cannot be caught by try-catch blocks. Therefore, the exception cannot be handled, and the transaction will fail.

NEW QUESTION # 165
Which exception type cannot be caught?

Answer: A

Explanation:
The exception type that cannot be caught is the LimitException. This exception is thrown when some governor limit is exceeded (like SOQL query limits, number of records that can be processed in a transaction, etc.).
Salesforce doesn't allow developers to catch LimitException in order to maintain the multi-tenant environment and ensure that no single tenant consumes excessive resources.

NEW QUESTION # 168
A company's engineering department is conducting a month-long test on the scalability of an in-house- developed software that requires a cluster of 100 or more servers. Which of the following models is the best to use?

A. SaaS
B. PaaS
C. BaaS
D. laaS

Answer: D

Explanation:
Infrastructure as a Service (IaaS)is the best model for the scenario described because it provides on-demand access to compute, storage, and networking resources that are ideal for a scalable server cluster. IaaS allows the engineering team to rent infrastructure resources without having to invest in physical hardware, making it perfect for temporary or fluctuating workloads, such as scalability testing.
Key Characteristics of IaaS:
Full control over the operating systems and applications running on the servers.
Flexible resource allocation to support high scalability.
Ideal for custom software testing where specific server configurations may be needed.
Why not the other options?
PaaS (Platform as a Service):While PaaS is excellent for application development and deployment, it abstracts the infrastructure layer, which would limit the engineering team's control over the cluster's configuration.
SaaS (Software as a Service):SaaS delivers fully managed applications, not infrastructure or testing environments. It's irrelevant for this use case.
BaaS (Backend as a Service):BaaS is tailored to mobile or web application backend development, providing APIs and pre-built services, not infrastructure for a server cluster.
Platform Developer References:
While this question is broader than Salesforce-specific concepts, understandingIaaS vs. PaaSis relevant when working with Salesforce development. For example:
Salesforce operates as aPaaS(e.g., Force.com platform), allowing developers to build and deploy applications without managing underlying servers.
Testing scalability and performance at an infrastructure level (as in the question) would fall underIaaSconcepts, which Salesforce developers might encounter when integrating external services or infrastructure like AWS, Azure, or Google Cloud.
This foundational knowledge complements your understanding of cloud services in the Salesforce ecosystem.
