Broad network access. Broad network access is the correct answer because it describes the ability to access cloud resources (such as storage and databases) over the network via standard protocols (e.g., HTTP/HTTPS, SMB, NFS) from any device (laptop, smartphone, tablet) with an internet connection, without requiring the customer to manage the underlying physical infrastructure. This characteristic is defined by NIST SP 800-145 as 'capabilities are available over the network and accessed through standard mechanisms that promote use by heterogeneous thin or thick client platforms.'

Question 8

A user is unable to send emails with attachments larger than 25 MB. The organization has Microsoft 365 Business Standard. What should you do to increase the attachment limit?

Accepted Answer

Modify the maximum message size in the Exchange admin center. In Microsoft 365 Business Standard, the default maximum message size for email attachments is 25 MB. To increase this limit, you must modify the maximum message size setting in the Exchange admin center (EAC), which controls the transport limits for the organization. This is the correct administrative action to raise the attachment size threshold beyond the default.

They face new compliance regulations that require automatic data classification and retention policies across all Microsoft 365 workloads. They want to add these capabilities without replacing their existing licenses, and they want to minimize costs. What is the most cost-effective licensing strategy?

Accepted Answer

Add Microsoft 365 E5 Compliance add-on for all users. Microsoft 365 E5 Compliance is an add-on that provides advanced compliance features like automatic data classification and retention policies across all Microsoft 365 workloads. Since the company already has Microsoft 365 Business Standard licenses, adding this add-on is the most cost-effective way to meet the new regulatory requirements without replacing existing licenses.

Question 10

A company uses Infrastructure-as-a-Service (IaaS) from a cloud provider. They have deployed virtual machines running a custom application. The cloud provider supplies the physical hardware, networking, and storage. Who is responsible for patching the operating system of the virtual machines?

Accepted Answer

The customer. In an IaaS model, the cloud provider is responsible for the physical infrastructure (hardware, networking, storage), but the customer retains responsibility for the guest OS and application stack. Patching the operating system of virtual machines is a customer task because the customer controls the OS image and has full administrative access to the VM. This follows the shared responsibility model where the provider secures the hypervisor and physical layer, while the customer secures the OS and applications.

Answer

The cloud provider

Answer

Both the provider and the customer share equally

Answer

A third-party managed security service provider

Question 11

An organization needs to automatically delete Microsoft Teams chat messages after 90 days to comply with a data minimization policy. Which Microsoft Purview feature should they use?

Retention policies. Retention policies in Microsoft Purview are designed to either retain data for a specified period, delete it after that period, or both. For Microsoft Teams chat messages, a retention policy can be configured to automatically delete messages after 90 days, directly supporting a data minimization policy. This is the correct feature because it provides time-based deletion for compliance requirements.
