Understanding the Scenario:

A two-way replica exists between a parent geodatabase and a child geodatabase to share edits.

A schema change (adding the legal_area field) occurs in the parent geodatabase but is not applied to the child geodatabase.

The parent synchronizes the replica, attempting to push changes that include edits to the new field.

Replica Synchronization Behavior:

Schema Changes and Replication: Replication does not automatically synchronize schema changes such as adding new fields. Schema updates need to be manually applied to both parent and child geodatabases before synchronization.

Conflict during Synchronization: If schema changes (like adding a field) are made in the parent geodatabase but not replicated in the child geodatabase, synchronization attempts to apply edits referencing the missing field. This results in an error because the child geodatabase does not recognize the new field.

Reference:

Esri Documentation: Schema Changes and Replication.

Error Handling in Synchronization: Guidance on managing synchronization issues due to schema mismatches.

Why the Correct Answer is A: During synchronization, an error occurs because the legal_area field does not exist in the child geodatabase. Synchronization cannot succeed unless both replicas have compatible schemas.

To allow editors to see changes made to the default version in their child versions without reconciling, the dataset must be registered as traditional versioned with the option to move edits to base.

1. How This Versioning Method Works

When registering data as traditional versioned with the option to move edits to base, changes made in the default version are immediately visible to all child versions without requiring reconciliation.

This method directly updates the base table for default version edits, bypassing the delta tables used in standard traditional versioning workflows.

2. Why Use This Method?

Immediate Visibility: Editors can see default version updates in their child versions without the need for reconciliation or posting.

Simplified Workflow: Reduces the overhead of managing version reconciliation and posting for users who only need to view updates.

3. Why Not Other Options?

Branch Versioned with Global IDs and Editor Tracking Enabled:

Branch versioning is designed for feature services and web-based editing workflows. It does not allow direct visibility of default version changes in child versions.

Traditional Versioned with Archiving and Editor Tracking Enabled:

This method tracks historical changes but does not allow child versions to see updates in the default version without reconciliation.

Steps to Register Data with Move Edits to Base Option:

In ArcGIS Pro, right-click the dataset or feature class and select Manage > Register as Versioned.

Check the option 'Move edits to base' during registration.

Save the changes and verify that editors can view default version changes without reconciliation.

Reference from Esri Documentation and Learning Resources:

Traditional Versioning with Move Edits to Base

Conclusion:

Registering the dataset as traditional versioned with the option to move edits to base ensures that editors can see changes made to the default version in their child versions without requiring reconciliation.

Scenario Overview:

An editor updates 500,000 records in a child version of the Default version using a field calculation.

Another editor updates the Default version, and the child version is reconciled with Default.

What Happens During Reconciliation?

In traditional versioning, edits to feature classes are stored in the Adds and Deletes tables.

During reconciliation:

Changes in the child version that differ from the Default version are duplicated in the Adds and Deletes tables to track the differences.

This allows conflicts to be detected and resolved while preserving all edits. (ArcGIS Documentation: Traditional Versioning Workflow)

Alternative Options:

Option B: They will be migrated to the Base table

Migration to the base table occurs only when changes are posted and the geodatabase is compressed.

Option C: They will be removed from the States repository table

The States repository table tracks state transitions and is unaffected during reconciliation.

Thus, during reconciliation, the 500,000 records are duplicated in the Adds and Deletes tables to manage and detect conflicts.

Scenario Overview:

The analyst creates a join between a large dataset and a nonspatial table to calculate an attribute field.

An error occurs, indicating that the join field is not indexed.

Cause of the Problem:

Joins between datasets rely on indexed fields to optimize the join operation. Without an index, the system must perform a full table scan, which can lead to errors or slow performance when working with large datasets.

Solution:

Running the Add Attribute Index tool creates an index on the join field, enabling efficient joining operations. (ArcGIS Documentation: Attribute Indexes)

Steps to Resolve:

Open the Add Attribute Index tool in ArcGIS Pro.

Select the nonspatial table as the input dataset.

Choose the field used in the join operation as the field to index.

Run the tool to create the attribute index.

Alternative Options:

Option A: Add Spatial Index is irrelevant for nonspatial data.

Option C: Rebuild Indexes reorganizes existing indexes but cannot create new ones, which is required here.

Thus, the analyst should run the Add Attribute Index tool to resolve the error.

Scenario Overview:

Multiple editors need to collaboratively edit the same dataset using a web application.

Requirements:

Editors work in isolation until they reach a stopping point.

Edits are shared with others at the stopping point.

Editors can view shared edits without sharing their own.

Branch Versioning in Enterprise Geodatabases:

Branch versioning is specifically designed for collaborative editing in web-based workflows.

It supports isolated editing by creating branches for each editor and allows users to reconcile and post changes at their discretion.

Editors can choose to reconcile shared changes without posting their own edits, fulfilling the requirement to view shared edits without sharing their own. (ArcGIS Documentation: Branch Versioning)

Key Features of Branch Versioning:

Supports Web Applications: Designed to work seamlessly with feature services, enabling real-time collaborative editing.

Isolation: Each editor can edit independently in their branch.

Reconciliation: Editors can reconcile and view changes made by others without posting their edits.

Flexible Sharing: Editors control when to post edits.

Alternative Options:

Option B: Traditional versioned with editor tracking enabled:

Traditional versioning supports isolated editing, but it does not provide the flexibility to view shared changes without posting your own edits.

It is also not as well-suited for web-based collaborative workflows.

Option C: Traditional versioned with the option to move edits to base:

Moving edits to base bypasses versioning workflows entirely and is not designed for collaborative editing.

Thus, branch versioning is the optimal solution for the requirements of this collaborative editing workflow in a web application.
