Microsoft 365 E5 Security add-on provides advanced anti-phishing and anti-malware protection via Microsoft Defender for Office 365 Plan 2 and includes Microsoft Defender for Endpoint Plan 2 for EDR capabilities.

Microsoft 365 Defender (formerly Microsoft Threat Protection) includes advanced hunting capabilities that allow security teams to run Kusto Query Language (KQL) queries across email, endpoints, identities, and cloud apps.

Add the Microsoft 365 E5 Security add-on for each user.. Option C is correct because the Microsoft 365 E5 Security add-on bundles Microsoft Entra ID Premium P2 and Microsoft Defender for Identity (along with other security features) at a lower per-user cost than purchasing them separately, and it can be added to an existing E3 subscription without upgrading the entire license. This provides the required identity protection capabilities cost-effectively for all 300 users.

Accepted Answer

Microsoft Defender for Cloud Apps. Microsoft Defender for Cloud Apps is a Cloud Access Security Broker (CASB) that provides visibility into shadow IT, controls over user access to SaaS applications, and data protection policies. It is the most cost-effective add-on for this specific requirement because it can be licensed standalone without requiring higher-tier Microsoft 365 or Entra ID plans, and it directly addresses the need to monitor and control SaaS app usage.

A company has 250 users with Microsoft 365 E3 licenses.

They want to keep their existing E3 subscriptions and minimize additional costs. What is the most cost-effective licensing approach?

Accepted Answer

Purchase the Microsoft Defender for Microsoft 365 Plan 2 add-on and the Microsoft 365 E5 eDiscovery and Audit add-on separately.

This avoids the cost of upgrading all users to E5 or purchasing broader suites like E5 Security or E5 Compliance, which include features not required.

A company currently has Microsoft 365 E3 licenses for all 200 users.

They also want to allow dial-in audio conferencing for online meetings. They want to minimize additional costs while keeping existing E3 subscriptions. What is the most cost-effective licensing strategy?

Accepted Answer

Purchase the 'Phone System + Audio Conferencing' add-on for each user. Option C is correct because the 'Phone System + Audio Conferencing' add-on is a bundled SKU specifically designed to provide both PSTN calling capabilities (Phone System and Calling Plan) and dial-in audio conferencing for Microsoft Teams at a lower combined cost than purchasing the two add-ons separately. Since the company already has Microsoft 365 E3 licenses, they only need this single add-on per user to meet all requirements without upgrading to E5 or buying individual add-ons, minimizing additional costs.
