Pass the Esri ArcGIS Enterprise EGMP2201 Questions and answers with CertsForce

 Understanding the Scenario:

The request involves creating a view that dynamically combines data from aversioned feature classand anonspatial table.

The data needs to be from achild versionand updated dynamically.

 Key Considerations:

Versioned Feature Class:Standard feature classes in versioned geodatabases store edits in delta tables (adds and deletes). Accessing data from a specific version requires using theversioned view, which includes these edits.

Dynamic Updates:Views created on the versioned view ensure that the data reflects the most current version edits.

 Steps to Create the View:

Identify the versioned view for the feature class (created automatically during versioning).

Create a SQL query to join the versioned view and the nonspatial table on the appropriate key(s).

Save the SQL query as a database view.

 References:

Esri Documentation: Versioned Views.

Creating Views with Versioned Data: Guidelines for joining versioned views with other tables in SQL.

 Why the Correct Answer is C:Using the versioned view ensures that data reflects edits from the specified child version. Joining this view with the nonspatial table meets the requirement for dynamic updates. Options A and B would not provide data from the versioned child version dynamically.

When users cannot edit a traditionally versioned feature dataset after a new feature class is added, the feature dataset must bere-registered as versioned.

1. Why Re-Register as Versioned?

Adding a feature class to a versioned feature dataset requires re-registering the entire feature dataset for versioning.

This step ensures that the new feature class is included in the versioning system and can participate in versioned workflows.

2. Why Other Steps Didn't Resolve the Issue?

Checked Permissions: Correct permissions do not address the need to re-register after adding a feature class.

Checked Connection File: Ensuring the connection file uses traditional versioning does not resolve missing registration.

Rebuilt Indexes and Statistics: While this improves performance, it does not affect versioning.

3. Why Not Other Options?

Connect as Data Owner and Edit Data:

Even as the data owner, edits would not be possible until the feature dataset is re-registered.

Unregister the Feature Dataset as Versioned:

Unregistering would delete the versioning information, potentially causing data loss in the delta tables.

Steps to Re-Register the Feature Dataset as Versioned:

OpenArcGIS Proand connect as the data owner.

Right-click the feature dataset and selectManage > Register As Versioned.

Choose the option toPreserve edits to base tables(if required).

Save and test edits on the feature dataset.

Managing Versioned Feature Datasets

Conclusion:

The administrator shouldre-register the feature dataset as versionedto include the newly added feature class and resolve editing issues in the traditionally versioned environment.

When a database view performs poorly in a map, registering it with the geodatabase can significantly improve performance.

1. Why Register with the Geodatabase?

Registering a database view with the geodatabase integrates it into the geodatabase system, enabling:

Proper use of spatial indexes.

Optimization of queries by the geodatabase.

Improved handling of large datasets by leveraging geodatabase-specific performance enhancements.

2. Why Not Other Options?

Export to Shapefile:

Shapefiles are a flat file format that lacks indexing and performance optimization. Using shapefiles is not suitable for complex queries or large datasets.

Join to Another Feature Class:

Joining data does not address the root cause of performance issues in the view and may further degrade performance if the join adds complexity.

Steps to Register a Database View with the Geodatabase:

OpenArcGIS Proand connect to the database.

Use theRegister with Geodatabasetool, specifying the database view.

Configure the registration to include spatial indexes if the view contains spatial data.

Save and test the performance of the registered view in a map.

Additional Notes:

If the database view includes complex SQL logic, simplify the query if possible to further improve performance.

Ensure that the underlying tables in the view are properly indexed.

Improving Map Performance with Views

Conclusion:

Registering the database view with the geodatabase enables spatial indexing and geodatabase optimization, addressing performance issues and ensuring efficient rendering and querying.

In traditional versioning within an enterprise geodatabase, theDefaultversion often represents the published state of the database. Setting the Default version toprotectedensures that while all users can view it, only the geodatabase administrator or the version owner can edit it directly or post changes to it.

ArcGIS Pro

In the scenario provided, the editor follows these steps:

Default Version Set to Protected:This restricts editing and posting privileges to the geodatabase administrator or the version owner.

Creation of a Child Version from Default:The editor creates a new version branching from Default.

Child Version Set to Protected:This means only the editor (as the owner) or the geodatabase administrator can edit this child version.

Edits Saved to the Child Version:The editor makes and saves changes within this child version.

Attempt to Reconcile and Post to Default:The editor successfully reconciles but encounters an error during the post operation.

The error during the post operation arises because, with the Default version set to protected, the editor lacks the necessary permissions to post changes directly to it. Only the geodatabase administrator or the owner of the Default version possesses the authority to perform this action.

ArcGIS Pro

Analysis of Options:

Option A:Changing the access level of the child version from protected to public does not grant the editor the required permissions to post to the protected Default version.

Option B:Requesting the owner of the Default version (typically the geodatabase administrator) to perform the reconcile and post is appropriate. This individual has the necessary permissions to post changes to the protected Default version.

Option C:Creating a one-way replica and synchronizing is an unnecessary and complex approach for this situation.

Therefore, the editor shouldask the owner of Default to perform the reconcile and postto ensure the changes are integrated into the Default version.

To restrict access to specific fields in a feature class, the GIS data administrator should use adatabase view.

1. What is a Database View?

Adatabase viewis a virtual table created by a SQL query. It displays data from one or more tables or feature classes, but only the specified fields and rows are accessible.

Views allow the administrator to control the fields and records visible to users without altering the underlying data.

2. Why Use a Database View?

Provides fine-grained control over data access by limiting which fields (or rows) are visible to specific users.

Helps enforce data security policies in multi-user environments.

Can be shared as a read-only layer or with restricted update permissions, depending on the use case.

3. Why Not Other Options?

Layer File:

A layer file (*.lyr) only defines how data is symbolized and displayed. It does not restrict field access at the database level. Unauthorized users can still access hidden fields through direct database connections.

Query Layer:

A query layer allows for custom SQL queries when displaying data in ArcGIS but is not a security measure. Users can modify or bypass the query to access all fields.

Steps to Create a Database View:

Use SQL to define the view, specifying only the required fields:

CREATE VIEW restricted_view AS

SELECT field1, field2

FROM feature_class

WHERE ;

Grant permissions to the view for authorized users while restricting access to the base table.

Publish the view in ArcGIS as a read-only layer if needed.

Data Security in Enterprise Geodatabases

Conclusion:

Adatabase viewis the most effective method to restrict access to specific fields in a feature class, ensuring data security while providing flexibility in data sharing.

Scenario Overview:

The GIS data administrator is unable to upgrade the geodatabase because editors have active sessions and are working on editing workflows.

Active connections lock the geodatabase, preventing upgrades or maintenance operations.

Solution:

Editors mustdisconnect from their active sessionto allow the geodatabase upgrade to proceed. Disconnecting ensures no locks are held on the database objects.

The administrator can also useGeodatabase Administration toolsto manually disconnect all users if necessary.(ArcGIS Documentation: Disconnect Users)

Alternative Options:

Option A:Reconcile and post edit versions is unnecessary as the issue is related to active database sessions, not data versioning.

Option C:Saving edits and stopping editing sessions alone does not close the database connection, leaving locks in place.

Therefore, editors mustdisconnect from their active sessionfor the geodatabase upgrade to proceed.

 Understanding the Scenario:

A database exists but lacks the repository owner required for a geodatabase.

The GIS administrator has database administrator credentials to set up the geodatabase.

 Options Overview:

Create Enterprise Geodatabase:This tool creates a geodatabase in a relational database. It sets up the repository owner and adds the required system tables, schema, and configurations.

Enable Geodatabase:This tool enables geodatabase functionality in an existing database that already has the repository owner and structure. Since the repository owner is missing, this tool cannot be used.

Create Workflow Database:This tool is unrelated to creating or enabling geodatabases. It is used for managing workflows in a production environment.

 Steps to Use Create Enterprise Geodatabase:

Open theCreate Enterprise Geodatabasetool in ArcGIS Pro.

Provide the database connection information, including administrator credentials.

Specify the authorization file for geodatabase licensing.

Run the tool to create the geodatabase.

 References:

Esri Documentation: Create Enterprise Geodatabase.

 Why the Correct Answer is A:The Create Enterprise Geodatabase tool is specifically designed for initializing a geodatabase, including creating the repository owner and required system components. The other options are either not applicable or insufficient for the given scenario.

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

1. How This Versioning Method Works

When registering data astraditional 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:

InArcGIS Pro, right-click the dataset or feature class and selectManage > 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.

Traditional Versioning with Move Edits to Base

Versioning Options in Enterprise Geodatabases

Conclusion:

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

 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.

 References:

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.
