EGMP2201 Practice Exam Questions with Answers Enterprise Geodata Management Professional 2201 Certification

To create database connection files that point to a specific edit version for users, theGeodatabase Connection Propertiesoption should be used.

1. What are Geodatabase Connection Properties?

This option allows you to set specific connection details, such as the target version (edit version) within a traditionally versioned geodatabase.

It ensures that each user connects directly to their designated version, isolating edits and preventing conflicts in multi-user environments.

2. Why Use Geodatabase Connection Properties?

Provides control over which version of the geodatabase the user accesses.

Ensures security and consistency by directing users to their designated edit versions rather than the default version.

Allows administrators to pre-configure connection files for distribution to users.

3. Why Not Other Options?

Connection Properties:

Refers to general connection details like username, password, and server but does not allow specifying a particular version.

Database Properties:

Refers to database-level settings but does not configure specific user-level connection details, such as the target version.

Steps to Use Geodatabase Connection Properties:

InArcGIS Pro, go to theCatalog Pane.

Create a new database connection by selectingAdd Database.

In the connection properties dialog, specify:

The user’s credentials.

Thespecific versionthe user will edit under the Geodatabase Connection Properties section.

Save the connection file and distribute it to the user.

Versioned Database Connections

Conclusion:

UsingGeodatabase Connection Propertiesensures that each database connection file is pre-configured to point to the appropriate edit version for the user, enhancing security and workflow efficiency.

Scenario Overview:

The organization hasArcGIS Enterpriseand requires versioned editing.

The project mandates tracking which user deleted a feature from thedefault version.

Why Branch Versioned Editing?

Branch versioningsupports versioned editing workflows and integrates seamlessly witheditor tracking, including operations like tracking who deleted a feature.

It is ideal for web-based workflows inArcGIS Enterpriseand allows for direct interaction with feature services.

The default version remains accessible for analysis while enabling the organization to track user edits, including feature deletions.(ArcGIS Documentation: Branch Versioning)

Alternative Options:

Option B: Traditional versioned editingsupports versioned workflows but does not inherently track who deletes features unless additional workflows are implemented (e.g., custom fields or triggers).

Option C: Nonversioned editingdoes not support versioning workflows or user tracking.

Thus,branch versioned editingis the best workflow to support versioned editing while tracking deleted features.

Scenario Overview:

The wells feature class has one row per well.

The well_inspections table has one row for each inspection of a well.

Inspection dates from the well_inspections table need to be displayed as labels clustered around each well on the map.

The goal is to establish a connection between these two datasets without permanently joining them, as the data is being displayed dynamically (inspection dates are clustered around the wells).

Relates in Geodatabases:

A relate is a type of table association in which tables are linked by a common key field but remain separate.

Relates allow for dynamic queries to retrieve related records without duplicating or permanently associating the data.

Using a relate, you can query all inspection dates for a specific well dynamically, display them on the map as labels, and preserve the integrity of both the wells and inspections datasets.

(ArcGIS Documentation: Relates)

Alternative Options:

Option A: Join

A join merges two tables into one virtual table, based on a shared key. However, this approach is static and inappropriate for displaying dynamically clustered labels since the tables would need to be rejoined after every update.

Option C: Relationship Class

A relationship class is a more permanent association that enforces rules between two datasets. It is ideal for maintaining relationships between data but is unnecessary for dynamically labeling inspection dates on the map.

Thus, a relate is the most efficient and appropriate option for this scenario.

Scenario Overview:

The GIS administrator needs to create asynchronized copyof a branch versioned dataset.

Both copies must allowediting.

Why Geodatabase Replication?

Geodatabase replicationsupports the creation of synchronized copies of datasets while allowing edits in both the parent and child geodatabases.

Forbranch versioned data, replication ensures that edits made in either the parent or child geodatabase can be synchronized using a two-way replica.(ArcGIS Documentation: Geodatabase Replication)

Key Features of Geodatabase Replication for This Scenario:

Two-way replicationenables editing on both sides while synchronizing changes.

Supportsbranch versioning, ensuring versioned workflows remain intact.

Maintains schema consistency across both geodatabases.

Alternative Options:

Option A: Distributed Collaboration

Collaboration is suitable for sharing data across ArcGIS Enterprise environments but does not support active synchronization for editing on both sides.

Option C: DBMS Replication

DBMS-level replication handles raw data replication but does not preserve geodatabase-specific functionalities, such as branch versioning.

Thus,geodatabase replicationis the correct method for synchronizing and editing branch versioned datasets in both geodatabases.

Scenario Overview:

Multiple editors need tocollaboratively editthe same dataset using a web application.

Requirements:

Editors work inisolationuntil 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 inweb-based workflows.

It supportsisolated editingby creating branches for each editor and allows users to reconcile and post changes at their discretion.

Editors canchoose 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 versioningis the optimal solution for the requirements of this collaborative editing workflow in a web application.

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.

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.

References from Esri Documentation and Learning Resources:

Registering Views with a Geodatabase

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.

When users experience performance issues while adding data from child versions in a complex traditional version tree, it often indicates problems with thebase tables. TheAnalyze Base Tables For Selected Datasetsparameter is the most relevant in this case.

1. Role of Base Tables in Traditional Versioning

In traditional versioning, thebase tablestores the original data for the feature class or table. Changes made in child versions are tracked in delta tables (Adds and Deletes).

If the base table is not optimized (e.g., outdated statistics, fragmented indexes), performance can degrade when querying or rendering data.

2. Why Analyze Base Tables?

TheAnalyze Base Tables For Selected Datasetsparameter evaluates and updates the database statistics for the base tables to improve query optimization.

This process ensures the database query optimizer can make efficient decisions when retrieving data.

3. Why Not Other Options?

Include System Tables:

This analyzes geodatabase system tables, which are crucial for administrative tasks but unrelated to performance issues with user datasets.

Analyze Archive Tables For Selected Datasets:

This is specific to datasets with archiving enabled. There is no mention of archiving being used in this scenario.

Steps to Analyze Base Tables:

OpenArcGIS Proor use a Python script with theAnalyze Datasetstool.

Specify the datasets with performance issues.

Select theAnalyze Base Tables For Selected Datasetsparameter.

Run the tool and monitor the updated statistics.

References from Esri Documentation and Learning Resources:

Analyze Datasets Tool

Improving Query Performance

Conclusion:

TheAnalyze Base Tables For Selected Datasetsparameter should be used to update statistics and improve performance when adding data from child versions in traditional versioning.

Scenario Overview:

The administrator needs to store attributes for valves (e.g., color, model, and size).

Pick listsmust display only valid combinations of these attributes.

Why Contingent Values?

Contingent valuesallow geodatabases to enforce specific, dependent attribute combinations.

For example, if certain sizes are only valid for specific models and colors, contingent values ensure only permitted combinations are displayed in pick lists.(ArcGIS Documentation: Contingent Values)

How Contingent Values Work:

Attribute domains are defined for individual fields (e.g., color, model, size).

Contingent value rules are configured to establish relationships between the fields, restricting invalid combinations.

When editing data, pick lists dynamically adjust based on contingent value rules, showing only valid options.

Alternative Options:

Option A: Domains

Attribute domains enforce constraints on individual fields but cannot define dependencies between fields.

Option B: Subtypes with domains

Subtypes group features into categories with distinct domain rules but do not support interdependent attribute combinations.

Thus,contingent valuesare the appropriate geodatabase capability to configure pick lists for valid attribute combinations.

To migrate an enterprise geodatabase to another server while changing its name and repository table owner, creating anew enterprise geodatabaseis the most appropriate workflow.

1. Why Create a New Enterprise Geodatabase?

New Geodatabase Name: Creating a new geodatabase allows specifying a different name for the database.

Change Repository Table Ownership: During the setup of the new geodatabase, the repository tables can be assigned to a new owner (e.g., DBO instead of SDE).

Fresh Configuration: This method provides full control over database settings, structure, and ownership during migration.

2. Why Not Other Options?

Restore a Database Backup:

Restoring a backup would preserve the original database name and ownership settings, which conflicts with the requirement to change these configurations.

Migrate Storage Geoprocessing Tool:

This tool is used for changing the storage type of geodatabase tables (e.g., from binary to XML). It is not designed for migration or renaming geodatabases or altering repository table ownership.

3. Steps to Create a New Enterprise Geodatabase:

Create the New Geodatabase:

Use theCreate Enterprise Geodatabasegeoprocessing tool in ArcGIS Pro or database-specific tools to set up the new geodatabase on the target server.

Configure the repository tables to use the desired owner (e.g., DBO).

Export Data from the Old Geodatabase:

UseGeodatabase replication,Export to File Geodatabase, or other export tools to migrate data to the new geodatabase.

Import Data to the New Geodatabase:

Load the exported data into the new geodatabase using theImport/Load Datatools.

Update Services and Connections:

Update database connection files and any published services to point to the new geodatabase.

References from Esri Documentation and Learning Resources:

Creating an Enterprise Geodatabase

Migrating Enterprise Geodatabases

Conclusion:

Creating anew enterprise geodatabaseis the best method to meet the requirements of renaming the database and changing the repository table owner.

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.

To ensure that the parent geodatabase can be fully compressed, even with unacknowledged data change messages, the replication must be configured toreplicate only the base tables.

1. What Happens with Unacknowledged Messages?

In traditional one-way replication, unacknowledged data change messages in the delta tables (Adds and Deletes) prevent full compression of the parent geodatabase.

By replicating only the base tables, the replication avoids using delta tables entirely, allowing the geodatabase to be fully compressed.

2. Why Replicate Only the Base Tables?

No Dependency on Delta Tables: This configuration ensures that the replication is based directly on the base table contents. As changes are not recorded in delta tables for replication, the parent geodatabase can be fully compressed without any impact.

Read-Only Copies: The replicated data in the child geodatabase will be read-only, which aligns with the requirement for regional offices.

3. Why Not Other Options?

Use the Full Replica Access Type:

Full replica access allows editing in the child geodatabase, which is unnecessary for read-only requirements. It also uses delta tables, preventing full compression.

Use the Archiving Option:

Archiving tracks historical edits and is unrelated to the replication or compression process. It does not solve the problem of unacknowledged messages blocking compression.

Steps to Set Up One-Way Replication with Base Tables:

OpenArcGIS Proand connect to the parent geodatabase.

Use theCreate Replicatool and selectOne-Way Replication.

Choose the option to replicatebase tables onlyduring the configuration process.

Define the datasets to replicate and complete the replication setup.

References from Esri Documentation and Learning Resources:

One-Way Replication Overview

Compressing Enterprise Geodatabases

Conclusion:

Configuring replication toreplicate only the base tablesensures that the parent geodatabase can be fully compressed, even with unacknowledged data change messages.

To minimize the number of rows created in the database while performing versioning workflows (loading, quality checking, reconciling, and posting),Traditional versioning without the archiving optionis the best choice.

1. Traditional Versioning Without Archiving

This method stores edits indelta tables(Adds and Deletes) rather than directly in the base table.

Without the archiving option, the system does not create additional rows to track historical changes, which helps reduce the number of rows.

2. Why It’s Ideal for This Workflow

Load Data: Data is directly inserted into the delta tables, keeping base tables untouched.

Quality Verification: Edits can be reviewed and adjusted without additional overhead.

Reconcile and Post: Only the changes made during the session are pushed to thedefault version, and unnecessary rows are avoided.

3. Why Not Other Options?

Traditional Versioning with Archiving Option:

Archiving tracks historical changes, creating additional rows for each edit in the archive tables. This increases storage and processing overhead.

Branch Versioning:

Branch versioning stores all changes in a single table and is designed for web services workflows. It may not minimize row creation compared to traditional versioning.

Steps for the Workflow:

EnableTraditional Versioningfor the target dataset without enabling archiving.

Load the large dataset into a new version created for this purpose.

Verify the data quality by querying and editing the version.

Reconcile the version with the default version, resolve conflicts, and post changes to default.

Archiving in Enterprise Geodatabases

Branch Versioning vs. Traditional Versioning

Conclusion:

UsingTraditional versioning without the archiving optionensures the creation of the fewest number of rows while maintaining data integrity and supporting the described workflow.

? Understanding the Scenario:

ArcGIS Pro users needUndo/Redo functionality, which is available in versioned workflows.

SQL users also need to edit the dataset, requiring direct access to the database tables.

These requirements point to a need for a versioning method that supports both ArcGIS client workflows and SQL-based edits.

? Versioning Methods Overview:

Nonversioned Editing:Nonversioned editing allows direct editing of the database but does not support Undo/Redo functionality in ArcGIS Pro, making it unsuitable for this scenario.

Traditional Versioning:

Supports Undo/Redo functionality for ArcGIS Pro users.

Stores edits in delta tables (adds and deletes) to manage versions.

SQL users can access and edit the base tables, making it compatible with their needs.

Branch Versioning:Branch versioning supports modern workflows and web services but requires a service-based approach for editing. It does not allow direct SQL edits, making it unsuitable for this scenario.

? Steps to Implement Traditional Versioning:

Enable traditional versioning on the dataset in the enterprise geodatabase.

Ensure appropriate permissions are set for SQL users to access and edit the base tables.

ArcGIS Pro users will work in the versioned environment, allowing Undo/Redo operations during their edits.

? References:
