Question 5

A developer has identified a method in an Apex class that performs resource intensive actions in memory by iterating over the result set of a SOQL statement on the account. The method also performs a DML statement to save the changes to the database.

Which two techniques should the developer implement as a best practice to ensure transaction control and avoid exceeding governor limits'*

Choose 2 answers

AUse the @ReadOnly annotation to bypass the number of rows returned by a SOQL.

BUse partial DML statements to ensure only valid data is committed.

CUse the System.limit class to monitor the current CPU governor limit consumption.

DUse the Database.Savepoint method to enforce database integrity.

Answer : C, D

Question 6

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?

APaaS

BSaaS

CBaaS

DlaaS

Answer : D

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 Reference: While this question is broader than Salesforce-specific concepts, understanding IaaS vs. PaaS is relevant when working with Salesforce development. For example:

Salesforce operates as a PaaS (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 under IaaS concepts, 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.

Question 7

DDev Hub
