Pass the ServiceNow Certified Technical Architect CTA Questions and answers with CertsForce

Application layer security in ServiceNow focuses on protecting data and functionality within the ServiceNow application itself. The following components contribute to this:

A. Multi-Factor Authentication (MFA): MFA adds an extra layer of security by requiring users to provide multiple forms of authentication (e.g., password, security token, biometric verification) to access the application.

C. Access Control Lists (ACLs): ACLs define which users or roles have permission to access, modify, or delete specific data and functionality within the application.

E. IP address access control: While technically a network layer control, IP address access control is often implemented and managed within the ServiceNow application. It restricts access to the instance based on IP address ranges.

Why not the other options?

B. Platform Encryption (PE): This is a broader encryption solution that protects data at rest across the platform, not specifically at the application layer.

D. Full Disk Encryption (FDE): This encrypts the entire hard drive of the server where the ServiceNow instance is hosted, providing protection at the infrastructure level, not the application layer.

To control access to sensitive data at the field level, the system administrator should use Column Level Encryption (CLE).

Here's how CLE works:

Field-Level Encryption: CLE allows you to encrypt specific fields within a table, ensuring that only authorized users with the necessary decryption keys can access the data.

Granular Control: You can define different encryption keys for different fields or groups of fields, providing fine-grained control over data access.

Role-Based Access: You can grant access to decryption keys based on user roles, ensuring that only authorized personnel can view sensitive information.

Why not the other options?

A. PI1 Encryption: This is not a standard ServiceNow encryption feature.

C. Cloud Encryption: This is a broader term for encryption solutions provided by cloud providers, not a specific ServiceNow feature.

D. Full Disk Encryption (FDE): This encrypts the entire hard drive, not individual fields within the application.

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.

The primary purpose of analyzing an organization's existing architecture as a Certified Technical Architect (CTA) is to identify issues and gaps in the system. This analysis helps to:

Understand the Current State: Gain a clear picture of the current architecture, including its components, integrations, and limitations.

Identify Pain Points: Pinpoint areas where the architecture is not meeting business needs or causing challenges.

Assess Risks: Evaluate potential risks and vulnerabilities within the architecture.

Inform Recommendations: Provide a basis for making recommendations for improvements and future architecture planning.

Why not the other options?

A. To evaluate existing system performance: While performance is important, it's one aspect of the broader architectural analysis.

C. To recommend a product roadmap: A product roadmap might be an outcome of the analysis, but the primary purpose is to understand the current state and identify areas for improvement.

D. To evaluate existing testing practices: Testing practices are important, but they are not the primary focus of architectural analysis.
