Question 1

For full authentication, which of the following might require both a password and a security question?

Accepted Answer

Multi-Factor Authentication

Answer

Multi-Factor Authentication (MFA) is a security system that requires more than one method of verification to grant access. It typically combines something the user knows (like a password), something the user has (like a phone for a code), or something the user is (like a fingerprint). Requiring both a password and a security question adds an extra layer of security, making it a form of MFA.

Question 2

When you try to create several managed Microsoft SQL Server instances in an Azure environment, you get a notice telling you that your Azure subscription limitations need to be increased.
What should you do to increase the limits?

Accepted Answer

Create a new support request

Answer

Azure subscriptions have default service limits to manage resource consumption and prevent abuse. If you encounter a message indicating that your subscription limits need to be increased for a specific service, the standard procedure is to submit a new support request to Microsoft Azure. The Azure support team will then review your request and adjust the limits if appropriate.

Question 3

In Azure, a platform as a service (PaaS) solution that hosts web apps gives you complete control over the operating systems that host applications. Is the statement correct?

Accepted Answer

No

Answer

Platform as a Service (PaaS) solutions, such as Azure Web Apps, provide a managed environment for deploying and running applications. While PaaS gives developers control over their applications and data, it abstracts away the underlying infrastructure, including the operating system. Microsoft manages the operating system, patching, and scaling, meaning users do not have complete control over the OS.

Question 4

_________ refers to a system's capacity to scale dynamically.

Accepted Answer

Elasticity

Answer

Elasticity refers to a system's capacity to automatically and dynamically scale resources up or down in response to changing demand. This means resources can be provisioned or de-provisioned quickly and automatically to match workload fluctuations, ensuring optimal performance and cost efficiency. Scalability is a broader concept, but elasticity specifically emphasizes this dynamic, automatic adjustment.

Question 5

By changing the pricing tier, a Platform as a Service (PaaS) solution that runs web apps in Azure can be provided additional memory. Is the statement correct or incorrect?

Accepted Answer

Yes

Answer

In Azure, many Platform as a Service (PaaS) solutions, including web apps, offer different pricing tiers that correspond to varying levels of resources like CPU, memory, and storage. By changing the pricing tier (e.g., from Basic to Standard or Premium), you can easily scale up the underlying resources, including providing additional memory, without needing to reconfigure the application or infrastructure.
