Question 20

In a Cisco Unified Communications Manager (CUCM) environment, you are tasked with configuring partitions to manage call routing effectively. You have three departments: Sales, Support, and Administration. Each department should only be able to call specific numbers within their own partition and should not have access to the numbers in the other departments\' partitions. If a user in the Sales department attempts to call a number in the Support partition, what is the expected behavior of the CUCM system, assuming the partitions are correctly configured and the calling search space is set up appropriately?

Accepted Answer

The call will be blocked, and the user will receive a busy signal.

Question 21

A company is designing a numbering plan for its new VoIP system, which will support multiple branches across different regions. The company has decided to implement a 4-digit extension numbering scheme. Each branch will have a unique prefix to distinguish its extensions. If the company has 5 branches and wants to allocate 100 extensions per branch, what is the maximum number of unique extensions that can be created using this numbering plan, and how should the prefixes be structured to ensure no overlap?

Accepted Answer

500 unique extensions with prefixes ranging from 1000 to 5000

Question 22

In a corporate environment, a security analyst is tasked with evaluating the effectiveness of endpoint security solutions across various devices. The organization has deployed a combination of antivirus software, endpoint detection and response (EDR) systems, and mobile device management (MDM) solutions. The analyst notices that while the antivirus software is effective against known malware, it fails to detect sophisticated threats that exploit zero-day vulnerabilities. The EDR system, however, provides real-time monitoring and can respond to suspicious activities. Given this scenario, which approach should the analyst recommend to enhance the overall security posture of the organization?

Accepted Answer

Implement a layered security strategy that combines antivirus, EDR, and MDM with regular updates and threat intelligence feeds.
