ServiceNow Certified Technical Architect CTA Exam Practice Test

Answer : A

In the context of ServiceNow technical governance, environmental management primarily focuses on defining the instance structure. This includes:

Instance Segmentation: Determining how many instances are needed (e.g., separate instances for development, test, and production) and how they relate to each other.

Instance Upgrades: Establishing policies and procedures for managing instance upgrades, including scheduling, testing, and communication.

Instance Maintenance: Defining guidelines for ongoing maintenance activities, such as patching, backups, and performance monitoring.

Why not the other options?

B . Data ownership: Data ownership is typically addressed within data governance policies, not specifically environmental management.

C . User access policies: User access policies are part of security governance and are handled through roles, permissions, and access control lists.

D . Application customization: Application customization is governed by development and configuration standards, not directly by environmental management.

Answer : B

The Identification and Reconciliation (I&R) module uses identification rules to uniquely identify CIs. These rules help the system determine if a CI discovered or imported from a data source already exists in the CMDB or if it's a new CI.

Here's how it works:

Identification Rules: These rules define criteria for matching CIs based on their attributes (e.g., serial number, MAC address, hostname).

Matching and Reconciliation: When new data comes in, the I&R engine applies the rules to find potential matches. If a match is found, the system can either update the existing CI with new information or flag it as a potential duplicate for review.

Why not the other options?

A: While the I&R engine can facilitate merging duplicates, it doesn't automatically merge them without human review and approval.

C: Data source validation is important, but it's not the primary function of the I&R engine in duplicate reduction.

D: Assigning unique identifiers is a function of the CMDB itself, not specifically the I&R engine.

Answer : A

In the final planning stage of a ServiceNow integration, the CTA should prioritize assessing network and system communication needs. This involves:

Connectivity: Verifying network connectivity between ServiceNow and the external system. This includes checking firewalls, ports, and any required network configurations.

Protocols: Determining the communication protocols to be used (e.g., REST, SOAP, JDBC).

Security: Ensuring secure communication channels, including authentication and encryption requirements.

Performance: Considering bandwidth requirements and potential performance impacts on both systems.

Why not the other options?

B . Determining the color scheme for integration UI: While UI considerations are important, they are not the primary focus during the technical details gathering stage.

C . Planning the communication for the integration go-live: Communication planning is important but separate from the technical details of the integration itself.

D . Estimating the projected integration data metrics: Data volume estimates are useful, but the primary focus is on ensuring successful communication between the systems.

Answer : B

In this scenario, the Executive Steering Board is the most appropriate group to consult. Here's why:

Portfolio Realignment: This implies significant changes to the overall IT portfolio, which falls under the purview of the Executive Steering Board. They have the authority to make strategic decisions about the IT portfolio and prioritize initiatives based on business goals and overall impact.

Why not the other options?

A . Demand Board: The Demand Board typically focuses on evaluating and prioritizing individual demands or requests, but they may not have the authority to make decisions about portfolio realignment.

C . Program Steering Committee: This committee focuses on the governance and oversight of specific programs, not on overall portfolio strategy.

D . Technical Governance Board: This board focuses on technical standards, architecture, and security, not on strategic portfolio decisions.

Answer : B, C, E

Effective error handling is crucial for maintaining the reliability and stability of ServiceNow integrations. Recommended strategies include:

B . Establish a process to review and monitor errors: Regularly review integration logs and error reports to identify trends, potential issues, and areas for improvement.

C . Classify errors into specific categories: Categorizing errors (e.g., data errors, connection errors, authorization errors) helps with troubleshooting and identifying root causes.

E . Log all errors to a centralized location: Maintain a centralized log of all integration errors for analysis and troubleshooting. This provides a comprehensive view of integration health.

Why not the other options?

A . Ignore minor errors to reduce system load: Ignoring errors can lead to data inconsistencies and integration failures. All errors should be addressed appropriately.

D . Create email notifications for all integration errors: While notifications can be useful for critical errors, sending emails for all errors can lead to alert fatigue and may not be the most efficient way to manage errors.

Answer : C

IP address access control is considered part of the network layer because it restricts access to the instance based on IP address ranges.

Here's why:

Network Layer Functionality: IP address filtering operates at the network level by controlling which IP addresses are allowed to connect to the ServiceNow instance. This is similar to firewall rules that control network traffic.

Application Layer Implementation: While the filtering might be implemented within the ServiceNow application (application layer), the underlying functionality is related to network access control.

Why not the other options?

A . It performs data tokenization and substitution for security: This is a data security technique, not related to network layer access control.

B . It uses encryption to protect data at rest in the ServiceNow instance: This is a data security measure, not network access control.

D . It manages user authentication to the ServiceNow platform: Authentication is a separate security layer (usually application layer) that verifies user identities.

Answer : B

To effectively manage risks during a go-live, it's essential to have a back-out plan and mitigation plan for unforeseen circumstances. This includes:

Back-out Plan: A detailed procedure for reverting to the previous system or version if the go-live encounters critical issues.

Mitigation Plans: Prepared responses for anticipated risks (e.g., data migration errors, performance issues, user resistance). These plans outline steps to address these risks if they occur.

Risk Assessment: A thorough risk assessment should be conducted before the go-live to identify potential risks and their likelihood.

Why not the other options?

A . A list of key performance metrics to track the performance: While performance monitoring is important, it's not the primary element for managing risks.

C . A detailed communication plan for all stakeholders: Communication is crucial, but it's a separate component of the go-live plan.

D . A schedule for user training and support sessions: User training and support are important but not directly related to risk management.
