DELL-EMC D-ZT-DS-23 Zero Trust Design 2023 Free Practice Test — 30 Questions

Question 1

In a corporate environment, a company implements Multi-Factor Authentication (MFA) to enhance its security posture. Employees are required to use a combination of something they know (a password), something they have (a smartphone app that generates a time-based one-time password), and something they are (biometric verification). If an employee\'s password is compromised but they still have their smartphone and their biometric data is intact, what is the likelihood of unauthorized access to their account, assuming the MFA system is correctly configured and operational?

Accepted Answer

The likelihood of unauthorized access is significantly reduced.

Question 2

In a corporate environment implementing a Zero Trust architecture, the evaluation of potential solutions must consider various criteria to ensure that they align with the organization\'s security objectives. If a company is assessing a new identity management solution, which of the following criteria should be prioritized to effectively evaluate its capability to support Zero Trust principles?

Accepted Answer

The solution's ability to enforce least privilege access and continuous authentication based on user behavior analytics.

Question 3

A company is evaluating the cost implications of implementing a Zero Trust security model across its infrastructure. The initial investment for the technology and training is estimated to be $500,000. Additionally, the company anticipates annual operational costs of $150,000 for maintenance and updates. If the company expects to reduce security breaches by 80%, which previously cost them $1,000,000 annually, what is the total cost savings over a 5-year period, considering the initial investment and ongoing costs?

Accepted Answer

$1,250,000

Question 4

A retail company is undergoing a PCI DSS compliance assessment. They have implemented a new payment processing system that encrypts cardholder data both in transit and at rest. However, during the assessment, it was discovered that the encryption keys used for this system are stored on the same server as the payment application. Considering the PCI DSS requirements, particularly those related to key management and data protection, which of the following statements best describes the compliance implications of this setup?

Accepted Answer

The setup is non-compliant because encryption keys must be stored securely and separately from the encrypted data to prevent unauthorized access.

Question 5

In a corporate environment, a security analyst is tasked with evaluating the effectiveness of the Endpoint Detection and Response (EDR) system after a recent malware attack. The EDR system reported 150 alerts over a 24-hour period, with 30 of those alerts being classified as high severity. The analyst needs to determine the percentage of high-severity alerts relative to the total alerts generated. Additionally, the analyst must assess the response time of the EDR system, which took an average of 5 minutes to respond to high-severity alerts. If the organization aims to reduce the response time to under 3 minutes, what percentage of alerts were high severity, and what implications does the current response time have on the overall security posture of the organization?

Accepted Answer

20% high severity alerts; the current response time indicates a need for improvement in incident response capabilities.
