Free Practice Questions for Esri EGMP2201 Exam

When users report that they are unable to connect to the geodatabase after nightly maintenance, and the GIS administrator can connect successfully, the issue is likely due to the geodatabase being set todeny new connectionsduring or after the maintenance process.

1. Geodatabase Maintenance and Connections

During maintenance, administrators often set the geodatabase to deny connections to prevent user interference.

If this setting is not reverted after maintenance, users will be unable to connect, but the administrator may still connect using their direct privileges.

2. Steps to Check if the Geodatabase is Accepting Connections

OpenArcGIS ProorArcGIS Enterprise Manager.

Go to the geodatabase properties.

Check the"Connections"setting:

Ensure the option"Accept Connections"is enabled.

3. Why Not Other Options?

Number of Maximum Connections:

While a connection limit could block users, the administrator would also face this issue if the limit was reached.

Correct Username and Password:

This is unlikely the issue if multiple users suddenly report the same problem after maintenance.

Conclusion:

The GIS administrator should check if thegeodatabase is accepting connectionsto resolve the issue.

For a large government organization requiring an equivalent data presence in a standby data center,database replicationis the ideal solution.

1. What is Database Replication?

Database replication involves duplicating data from a primary database to a secondary database in near real-time or on a scheduled basis.

This ensures that both databases are synchronized and capable of serving data if one fails.

2. Why Database Replication Fits the Requirement

Standby Data Center: Database replication provides a fully equivalent copy of the data in the secondary data center.

High Availability and Disaster Recovery: If the primary database is unavailable, the standby database can immediately take over, ensuring business continuity.

3. Why Not Other Options?

Geodatabase Replication:

While it is designed for replicating geodatabase content, it is typically used for GIS-specific workflows, such as syncing field edits. It does not ensure equivalence for non-spatial components of the database.

It is not ideal for large-scale, organization-wide replication needs.

Disconnected Synchronization:

This is used in offline editing workflows where devices sync their edits with a central database at a later time. It is not suitable for maintaining an equivalent standby database.

4. Types of Database Replication

Asynchronous Replication: Updates are replicated at scheduled intervals, offering flexibility but with slight delays.

Synchronous Replication: Updates occur in real-time, ensuring both databases are always identical.

Steps to Implement Database Replication:

Configure the primary and standby databases in the organization’s DBMS (e.g., SQL Server, PostgreSQL, Oracle).

Use the DBMS's built-in replication tools (e.g., SQL Server's Always On, PostgreSQL’s Streaming Replication).

Set up monitoring to ensure the replication process is functioning correctly.

Disaster Recovery with Database Replication

Conclusion:

Database replicationis the recommended technology to establish an equivalent data presence in a standby data center, ensuring high availability and disaster recovery.

When a database view is registered with the geodatabase, the geometry type, spatial reference, and row ID field are added to the geodatabase system tables. This enables ArcGIS to recognize and use the view effectively.

1. What Happens During Registration?

System Table Updates: Registering the view adds metadata to the geodatabase system tables, including:

The geometry type (e.g., point, polygon).

The spatial reference (coordinate system).

The row ID field used to uniquely identify rows.

This metadata ensures that the database view is treated as a spatial dataset within ArcGIS.

2. Benefits of Registration:

Spatial Functionality: Registered views can be used in ArcGIS for visualization, analysis, and querying.

Geodatabase Tools Compatibility: Tools like attribute editing and symbology work seamlessly with registered views.

3. Why Not Other Options?

Viewers Can Modify Which Fields Are Visible for the Database View:

The visibility of fields in a database view is determined by the SQL query used to create the view, not by the registration process.

The Registration Process Allows the Database Contents View to Be Edited Using ArcGIS Tools:

Registered views remain read-only in ArcGIS, regardless of registration. Registration does not allow editing the view’s contents.

Steps to Register a Database View with the Geodatabase:

OpenArcGIS Proand connect to the database.

Use theRegister With Geodatabasetool.

Specify the database view to be registered.

Confirm that the geometry type, spatial reference, and row ID field are properly recognized.

References from Esri Documentation and Learning Resources:

Registering Views with the Geodatabase

Geodatabase Metadata

Conclusion:

Registering a database view with the geodatabase ensures that thegeometry type, spatial reference, and row ID field are added to the system tables for reference, enabling ArcGIS to treat the view as a spatial dataset.

 Understanding the Scenario:

The enterprise geodatabase receives regular updates through a "push" SQL process from a federated database.

Business rules require transformations or corrections to attribute values during the data insertion process.

The GIS administrator needs a mechanism to ensure that attribute values adhere to these rules.

 Options Overview:

Attribute Rule:

Attribute rules can enforce data integrity by applying calculations or constraints during data editing.

With calculation rules, attribute values can be automatically derived based on specific logic, ensuring that values comply with business rules.

DBMS Trigger:DBMS triggers execute procedures when database events occur (e.g., an insert). However, they are managed outside of the geodatabase environment, making them less integrated with ArcGIS workflows.

Spatial View:A spatial view combines spatial and nonspatial data but does not enforce or modify attribute values during data loading or editing.

 Steps to Configure an Attribute Rule:

Define acalculation attribute ruleon the field requiring transformation.

Specify the logic to derive or validate the attribute value based on the business rules.

Apply the rule to the dataset.

As data is inserted, the rule ensures values are updated or corrected automatically.

 References:

Esri Documentation: Attribute Rules.

Attribute Rule Types: Best practices for using calculation and validation rules in enterprise geodatabases.

 Why the Correct Answer is A:Attribute rules are specifically designed to manage attribute values and ensure compliance withbusiness logic during data editing. DBMS triggers are external and less geodatabase-centric, while spatial views do not support value transformations during insertion.

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.

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.

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.

To track feature class changes while keeping thereconcile, post, and compress processesseparate from thereplica synchronization process, the best approach is tocreate a one-way replica using the archive option on Default.

1. Why Use a One-Way Replica on Default?

One-Way Replication:

Sends data changes from the parent (Default version) to the child geodatabase, ensuring that synchronization does not interfere with the parent geodatabase’s versioning operations.

Archive Option:

Archiving captures all changes to the feature class, providing a history of edits without requiring versioning in the replica.

2. Why Choose the Default Version?

Using the Default version as the parent ensures that all reconciled and posted changes are synchronized to the replica, making the synchronization independent of ongoing versioning workflows in the geodatabase.

3. Why Not Other Options?

Create a One-Way Replica Using the Archive Option on a Child Version of Default:

Replicating from a child version complicates workflows because the child version must be reconciled and posted to Default before updates are reflected in the replica.

Create a Two-Way Replica Using the Archive Option on Default:

Two-way replication synchronizes changes in both directions. This would integrate changes from the child geodatabase into Default, interfering with the reconciliation and posting processes.

Steps to Create the Replica:

Ensure archiving is enabled for the feature classes in the Default version.

Use theCreate Replicatool in ArcGIS Pro and selectOne-Way Replication.

Configure the replica to include the archive option.

Synchronize the replica as needed without affecting versioning processes in the parent geodatabase.

Conclusion:

To track changes while separating reconcile, post, and compress processes from synchronization, the GIS analyst shouldcreate a one-way replica using the archive option on Default.

 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.

 Understanding the Scenario:

The feature class cannot havearchiving enabled.

Archiving tracks changes over time and requires specific configurations in versioned datasets.

 Key Constraints for Enabling Archiving:

Archiving can only be enabled for feature classes registered asversioned without moving edits to base.

Versioned with move edits to base:This configuration directly edits the base table, bypassing the delta tables (adds and deletes) used in traditional versioning. Since archiving relies on delta tables to track changes, this configuration is incompatible with archiving.

Branch Versioned with Editor Tracking:Branch versioning supports editor tracking and web-based workflows but does not currently support archiving.

 Steps to Correct the Configuration:

Re-register the feature class asversioned without moving edits to base.

Enable archiving after re-registration.

 References:

Esri Documentation: Archiving Requirements.

Versioning and Archiving Compatibility: Best practices for configuring datasets for archiving.

 Why the Correct Answer is B:When a feature class is registered asversioned with move edits to base, it does not maintain delta tables, making it incompatible with archiving.
