 To create a form that will create a record for a custom object, the developer can use a Dynamic Form, which is a Lightning App Builder component that allows you to customize the fields and sections of a record page layout1. A Dynamic Form can also use visibility rules to display different fields based on the user’s profile, role, or other criteria2. To add the functionality to the Account record page, the developer can use a Dynamic Action, which is a way to configure actions on a record page without code3. A Dynamic Action can also use visibility rules to show or hide actions based on the user’s profile, role, or other criteria4. To restrict the functionality to a small group of users, the developer can create a Custom Permission, which is a way to grant access to custom processes or apps5. A Custom Permission can be assigned to a permission set or a profile, and then assigned to the users who need it. References:

In Apex, if a SOQL query returns more than one row and the result is assigned to a single sObject variable, an exception will be thrown. This is because a single sObject variable can only hold one record. In this case, since myAccount is declared as a single Account object, it cannot hold more than one record. If the SOQL query returns more than one Account, an unhandled exception occurs, and the code terminates. References: The behavior can be understood from the Apex Developer Guide under the section of SOQL Queries 

The provided code snippet is trying to update more than 200 Account records that belong to the ‘Technology’ industry in a single transaction. In Salesforce, there are governor limits that restrict the number of records that can be processed synchronously in a single transaction to prevent overconsumption of resources. If this limit is exceeded, the transaction will fail. This applies to both synchronous (D) and asynchronous (A) transactions.

References: The governor limits are well documented in Salesforce’s developer guide and official documentation. You can refer to these documents for detailed information on various types of governor limits including DML, SOQL, and record processing limits.

• SVG resources, content asset files, and static resources are three Salesforce resources that can be accessed from a Lightning web component. They are used to store and display images, icons, fonts, stylesheets, JavaScript libraries, and other files that are required by the component12.
• SVG resources are Scalable Vector Graphics files that can be used to create and display icons and images in a Lightning web component. They can be referenced by using the @salesforce/resourceUrl import in the JavaScript file of the component12.
• Content asset files are files that are uploaded to the Salesforce Content Library and can be used to store and display images and other media in a Lightning web component. They can be referenced by using the @salesforce/contentAssetUrl import in the JavaScript file of the component12.
• Static resources are files or archives that are uploaded to the Static Resources page in Salesforce Setup and can be used to store and access stylesheets, JavaScript libraries, fonts, and other files in a Lightning web component. They can be referenced by using the @salesforce/resourceUrl import in the JavaScript file of the component12.
• Third-party web components and all external libraries are not Salesforce resources that can be accessed from a Lightning web component. They are not supported or recommended by Salesforce for security and performance reasons12.
• Third-party web components are web components that are created by other vendors or developers and are not part of the Lightning web components framework. They may not follow the same standards, specifications, or best practices as Lightning web components and may introduce security risks or compatibility issues12.
• All external libraries are JavaScript libraries that are hosted on external servers or CDNs and are not part of the Salesforce platform. They may not be compatible with the Lightning web components framework or the Locker Service, which enforces strict security policies and restrictions on the code execution and access12.

A global picklist value set is a collection of values that can be shared across multiple picklist fields on different objects1. By using a global picklist value set, a developer can streamline the maintenance of the picklist and their values, as they only need to define the values once and reuse them across multiple fields. The global picklist value set also restricts the values to the ones defined in the value set, so that users cannot enter or select other values1.

Option B is incorrect, because creating the picklist on each object as a required field and selecting “Display values alphabetically, not in the order entered” does not streamline the maintenance of the picklist and their values, nor does it restrict the values to the ones mentioned above. The developer would still need to create and maintain the picklist values for each object separately, and the users could still enter or select other values that are not ‘High’, ‘Medium’, or ‘Low’.

Option C is incorrect, because creating the picklist on each object and selecting “Restrict picklist to the values defined in the value set” does not streamline the maintenance of the picklist and their values, either. The developer would still need to create and maintain the picklist values for each object separately, even if they use the same value set. The only benefit of this option is that it restricts the values to the ones defined in the value set.

Option D is incorrect, because creating the picklist on each object and adding a validation rule to ensure data integrity is not the best approach to streamline the maintenance of the picklist and their values, while also restricting the values to the ones mentioned above. The developer would need to write and maintain the validation rule for each object, which is more complex and error-prone than using a global picklist value set. The validation rule would also run after the user enters or selects a value, which is less user-friendly than preventing the user from entering or selecting an invalid value in the first place.
