Question 8

Which Azure service provides a way to run containerized applications using a managed Kubernetes service without needing to manage the Kubernetes control plane?

Accepted Answer

Azure Kubernetes Service (AKS). Azure Kubernetes Service (AKS) is the correct answer because it provides a managed Kubernetes environment where Microsoft handles the control plane (including the API server, etcd, and scheduler) while you only manage the worker nodes and your containerized applications. This aligns directly with the question's requirement of not needing to manage the Kubernetes control plane.

Answer

Azure Container Instances

Answer

Azure Service Fabric

Answer

Azure Batch

Question 9

Which Azure compute size family is optimized for memory-intensive workloads like large in-memory analytics or SAP HANA?

Accepted Answer

Memory-optimized VMs (M-series, E-series). Memory-optimized VMs, such as the M-series and E-series, are designed with a high memory-to-core ratio and large memory capacities (up to 12 TB for M-series) to handle workloads that require massive amounts of RAM, such as large in-memory analytics and SAP HANA. SAP HANA specifically requires certified VM sizes with sufficient memory to load the entire database into RAM, and Azure's M-series is SAP-certified for this purpose.

Answer

Compute-optimized VMs (Fsv2-series)

Answer

Storage-optimized VMs (Lsv2-series)

Answer

GPU VMs (NC-series)

Question 10

A company wants to move from paying large upfront costs for hardware to a model where they only pay for what they use on a monthly basis. This represents a shift from CapEx to which type of expenditure?

Accepted Answer

Operational expenditure (OpEx). This scenario describes a shift from Capital Expenditure (CapEx), where large upfront costs are incurred for hardware, to Operational Expenditure (OpEx), where costs are based on actual usage and billed monthly. In cloud computing, OpEx aligns with the consumption-based model, where you pay only for resources consumed (e.g., compute hours, storage GB) without upfront commitments. This is a core financial benefit of cloud services like Azure, enabling variable costs instead of fixed capital investments.

Answer

Direct expenditure

Answer

Indirect expenditure

Answer

Capital expenditure

Question 11

Which Azure feature enables organizations to review and recertify privileged role assignments on a scheduled basis?

Accepted Answer

Azure AD Access Reviews. Microsoft Entra ID Access Reviews allow administrators to configure periodic reviews of privileged role assignments, ensuring that only authorized users retain access. This feature directly supports recertification workflows by sending reviewers notifications and automatically removing stale assignments based on policy.

Answer

Azure AD Privileged Identity Management role history

Answer

Azure RBAC audit logs

Answer

Azure Policy RBAC compliance

Question 12

A company wants to enforce that all storage accounts use the 'Standard' performance tier and block creation of any 'Premium' storage accounts. Which Azure Policy effect could achieve this?

Accepted Answer

Deny. The Deny effect is the correct choice because it actively prevents the creation of Azure resources that do not comply with the policy definition. In this scenario, by assigning a policy with the Deny effect that targets storage accounts with the 'Premium' performance tier, Azure Resource Manager will block any request to create a Premium storage account, ensuring only 'Standard' tier accounts are provisioned.

Answer

Append

Answer

Audit

Answer

Disabled

Question 13

A company wants to ensure that all new Azure storage accounts have a specific encryption setting enabled. They also want to automatically remediate any existing non-compliant storage accounts without manual effort. Which Azure Policy effect should they use?

Accepted Answer

DeployIfNotExists. DeployIfNotExists is the correct effect because it not only evaluates the compliance of storage accounts against the encryption policy but also automatically deploys a remediation task (e.g., enabling encryption via a linked ARM template or Azure function) to bring non-compliant resources into compliance without manual intervention. This effect is specifically designed for scenarios where the resource itself needs to be modified or configured to meet the policy requirement.

Answer

Append

Answer

AuditIfNotExists

Answer

Deny

Question 14

Which Azure AI service converts spoken audio into text and text into spoken audio?

Accepted Answer

Azure Speech Service. Azure Speech Service provides both speech-to-text and text-to-speech capabilities, enabling bidirectional conversion between spoken audio and written text. It is the single Azure AI service that combines these two functions, unlike other services that handle only one direction or different tasks.

Answer

Question 15

A company transitions from on-premises IT, where they purchased servers upfront, to Azure, where they pay a monthly subscription for virtual machines. This is an example of moving from capital expenditure (CapEx) to which type of expenditure?

Accepted Answer

Operating expenditure (OpEx). Moving from purchasing servers upfront (CapEx) to paying a monthly subscription for Azure virtual machines shifts costs to an operational expense (OpEx). This is because Azure's pay-as-you-go model charges for compute resources as they are consumed, with no large initial investment, aligning with OpEx accounting where costs are incurred and deducted in the same period.

Answer

Variable expenditure

Answer

Consumption-based expenditure

Answer

Fixed expenditure
