  • How profiles and permission sets work together to grant object permissions.
  • Why a user's effective object access is always the union (most permissive) of all assigned profiles and permission sets.
  • How permission set groups aggregate multiple permission sets.
  • Difference between 'View All' and 'Read' object permissions and when each is the correct choice for a user who should see all records regardless of OWD.
  • 'View All Data' and 'Modify All Data' system permissions: what they override and which objects they apply to.
  • Why assigning 'View All Data' or 'Modify All Data' is architecturally equivalent to bypassing all record-level sharing.
  • How 'Modify All' object permission interacts with record-level sharing rules and OWD settings when a user must manage all records regardless of ownership.
  • Which object permission combination (Read, Create, Edit, Delete, View All, Modify All) is appropriate given a business role that needs to update existing records but never delete them?
  • Which permission set or profile configuration allows a user to create and edit Contacts but not delete them, while still viewing all related Accounts?
  • Selecting the minimum necessary object permissions for a read-only integration user that must access all Opportunity records without opening up record sharing broadly.
  • How muting permission sets within a permission set group can restrict specific permissions that member permission sets would otherwise grant.
  • How field-level security (FLS) interacts with page layouts to control field visibility and the authoritative control mechanism when both are configured differently.
  • Impact of setting a field to 'Read-Only' in FLS versus removing it from the page layout on API access and programmatic SOQL queries.
  • Which approach grants field-level read access to a subset of users without modifying the profile shared by all users in that role?
  • How to enforce that a sensitive custom field on Case is visible only to support managers using permission sets while keeping the field accessible to automation.
  • Given a scenario where a user can see a field on the page layout but not through the API, which FLS configuration is the cause and how to resolve it.
  • How record types in conjunction with profiles control which picklist values and page layouts a user sees.
  • When record types alone are insufficient for access control.
  • Choosing between page layout removal, FLS hidden, and record type restrictions to hide a set of fields from a specific user population in the UI.
  • Limitations of hiding data only at the UI layer when the data is still accessible via SOQL, API, or reports — and the recommended architectural fix.
  • How Salesforce Shield Platform Encryption differs from Classic Encryption.
  • Which encryption (Shield vs Classic) should be used to satisfy HIPAA requirements for a health data field.
  • Which combination of Platform Encryption, FLS, and object permissions is appropriate to protect PII fields from being viewed by support agents while allowing billing users access?
  • Given PCI compliance requirements, which access control mechanisms must be layered to prevent unauthorized users from viewing cardholder data fields in Salesforce?
  • Audit trail and event monitoring capabilities in Salesforce used to detect and report on unauthorized access attempts to sensitive data.
  • When should an architect recommend data masking via a custom solution versus native Salesforce field encryption for protecting PII in a multi-cloud integration?
  • Difference between 'with sharing', 'without sharing', and 'inherited sharing' in Apex and when each keyword is correct for a class that processes sensitive Contact records.
  • How SOQL in an Apex trigger enforces (or bypasses) record-level sharing depending on the class-level sharing declaration.
  • The correct approach when an Apex trigger must respect row visibility for non-admin users.
  • How WITH SECURITY_ENFORCED or stripInaccessible() in Apex enforces FLS and object-level permissions for programmatically queried data.
  • How the Security.stripInaccessible() method behaves when applied before DML operations to prevent unauthorized field writes.
  • A developer's Apex class runs in system mode and bypasses FLS. Which code-level changes enforce field security without breaking existing functionality?
  • How Visualforce and Lightning Web Components differ in enforcing FLS automatically, and what developers must do to avoid FLS bypass in each.
  • When a batch Apex job must access all records regardless of sharing but must still respect FLS, which class-level sharing keyword and SOQL approach is appropriate?

Given a set of conditions, recommend the appropriate organization-wide defaults to restrict access to records.

  • How OWD settings for a given object establish the baseline record access and why setting OWD to 'Public Read/Write' makes all sharing rules redundant.
  • When is 'Private' OWD appropriate versus 'Public Read Only', given a business requirement where managers should see all subordinate records but reps should only see their own?
  • The 'Controlled by Parent' OWD setting for a custom object and how it governs record access relative to the Lookup or Master-Detail parent relationship.

  • How external OWD settings differ from internal OWD settings and why they can be set independently for each object.
  • When setting a lower external OWD is architecturally required.
  • A company has internal OWD of Public Read Only for Accounts but needs portal users to see only their own account data. Which external OWD setting achieves this without additional sharing rules?

0/10

  • How super user access for partner portal users works.
  • When super user access should be used to grant broader record access within an account hierarchy.
  • A customer community user should see only their own Cases and Cases shared explicitly by a support agent. Which combination of OWD and sharing mechanism achieves this?
  • Guest user record access limitations (no role, no manual sharing).
  • Restrictions on the types of sharing rules that apply to guest users.
  • How to compensate for guest user limitations using public groups and criteria-based sharing rules for unauthenticated users.

Given a set of conditions, determine how record access overrides support the record access requirements.

0/8

  • How manual sharing allows record owners and administrators to grant one-time access and the limitations of manual shares when ownership changes.
  • When is manual sharing the appropriate override mechanism versus a permanent sharing rule, given a one-time cross-team collaboration requirement?
  • How 'View All' and 'Modify All' object permissions override all record-level sharing mechanisms, including OWD, sharing rules, and manual shares.
  • System Administrator profile access: why admins can see all records regardless of OWD and sharing rules, and how to model a scenario where even admins should be restricted.
  • How to use the 'Why can I see this record?' (Sharing Hierarchy / Record Access) tool in Salesforce to diagnose unexpected record visibility.
  • How the Sharing Debugger (Setup > Sharing Settings > Debug) works and what information it surfaces about a user's access to a specific record.

A junction object connects two objects in a many-to-many relationship using two master-detail relationships. Access to the junction record is determined by the user's access to the related master records rather than a standard sharing model.

Core information
  • A junction object is a custom object with two master-detail relationships connecting two other objects.
More details and nuances
  • The Sharing Setting attribute on the master-detail relationship field determines the access users must have to the master record to create or edit the junction record.
