Question 75

You plan to collect and analyze event details for five Azure virtual machines. You need to run queries to compare the event details collected from all the virtual machines. Which two tools should you use? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point.

A. Azure Service Health
B. Azure Service Bus
C. Azure Monitor
D. Azure Advisor
E. Log Analytics
Show Answer
Correct Answer: C, E
Explanation:
Azure Monitor collects telemetry and event data from Azure virtual machines, while Log Analytics provides the workspace and Kusto Query Language (KQL) capabilities to query and compare logs across multiple VMs. Azure Service Health reports Azure service incidents, Service Bus is a messaging service, and Advisor provides optimization recommendations rather than log analysis.

Question 79

Which cloud service model minimizes the management responsibility of a customer?

A. infrastructure as a service (IaaS)
B. platform as a service (PaaS)
C. software as a service (SaaS)
Show Answer
Correct Answer: C
Explanation:
Software as a Service (SaaS) minimizes the customer's management responsibility because the provider manages the application, platform, infrastructure, updates, maintenance, and much of the operational overhead. In comparison, PaaS still requires customers to manage their applications and data, while IaaS requires management of the operating system, middleware, runtime, applications, and data.

Correct Answer: locally-redundant storage (LRS)

For Azure exam purposes, premium block blob storage accounts are treated as supporting LRS only. Although newer Azure documentation allows ZRS for premium block blob accounts in certain regions, the word 'only' makes LRS the expected answer.

Question 81

DRAG DROP - Match the Azure storage services to the appropriate descriptions. To answer, drag the appropriate storage service from the column on the left to its description on the right. Each service may be used once, more than once, or not at all. NOTE: Each correct match is worth one point.
