Question 561
You have an accounting application named App1 that uses a legacy database.
You plan to move App1 to the cloud.
Which service model should you use?
A. platform as a service (PaaS)
*B. infrastructure as a service (IaaS)
C. software as a service (SaaS)
Explanation
Cloud Infrastructure-based Applications – It moves your existing on-premises apps to the Infrastructure as a Service (IaaS) platform or re-hosts them. Lift & Shift is a common term for this type of relocation. The programs will be nearly identical to what they were before, but they will now be able to run on cloud VMs.
Question 562
Which cloud computing model includes on-premises and cloud-based resources?
*A. hybrid
B. public
C. private
Explanation
A hybrid cloud sometimes called a cloud hybrid is a computing environment that combines an on-premises datacenter (also called a private cloud) with a public cloud, allowing data and applications to be shared between them. Some people define hybrid cloud to include “multicloud” configurations where an organization uses more than one public cloud in addition to their on-premises datacenter.
Question 563
Autoscaling is an example of __________________.
A. agility
*B. elasticity
C. Geo-distribution
D. predictability
Explanation
An Azure virtual machine scale set can automatically increase or decrease the number of VM instances that run your application. This automated and elastic behavior reduces the management overhead to monitor and optimize the performance of your application.
Also: Azure elasticity as a service is referred to a cloud service that enables in automatically scaling Azure hosted resources in par with the demand and configured parameters. It provides Azure Administrators with the ability to auto scale Azure infrastructure and resources as and when needed.
Question 564
Azure virtual networks deployed to the same Azure region are connected by default.
A. Yes
*B. No
Explanation
You would need to setup the VNET connections, for example with peering.
Note: You can connect virtual networks to each other with virtual network peering. These virtual networks can be in the same region or different regions (also known as Global VNet peering). Once virtual networks are peered, resources in both virtual networks can communicate with each other.
Question 565
Each Azure virtual network in a single resource group must have a unique name.
*A. Yes
B. No
Explanation
All Azure resource types have a scope that defines the level that resource names must be unique. A resource must have a unique name within its scope.
For example, a virtual network has a resource group scope, which means that there can be only one network named vnet-prod-westus-001 in a given resource group.
Question 566
The Azure virtual network’s address space must be unique within a subscription.
*A. Yes
B. No
Explanation
As you build your network in Azure, it is important to keep in mind the following universal design principles:
Ensure non-overlapping address spaces. Make sure your VNet address space (CIDR block) does not overlap with your organization’s other network ranges.
Question 567
Which term represents the ability to increase the computing capacity of a virtual machine by adding memory or CPUs?
A. agility
*B. vertical scaling
C. horizontal scaling
D. elasticity
Explanation
Vertical scaling, also known as scale up and scale down, means increasing or decreasing virtual machine (VM) sizes in response to a workload. Compare this behavior with horizontal scaling, also referred to as scale out and scale in, where the number of VMs is altered depending on the workload.
Question 568
What are two benefits of cloud computing? Each correct answer presents a complete solution.
NOTE: Each correct selection is worth one point.
*A. enables the rapid provisioning of resources
B. has increased administrative complexity
C. has the same configuration options as on-premises
*D. shifts capital expenditures (CAPEX) to operating expenditures (OPEX)
Explanation
Azure allows you to build, deploy, and manage apps more quickly and easily without having to buy and/or maintain the underlying infrastructure.
Azure provides flexibility between CapEx and OpEx
Capital expenditures generate benefits over a long period. These expenditures are generally nonrecurring and result in the acquisition of permanent assets.
Building an application could qualify as a capital expenditure. Example, Azure Reserved Instances (Azure RI) help Azure’s most active customers save on long- term VM usage reserving VMs in advance at a discounted price by committing to a one or three-year benefits.
Operating expenditures are ongoing costs of doing business. Consuming cloud services in a pay-as-you-go model could qualify as an operating expenditure.
Example, you pay for a service or product as you use it i.e. pay-as-you-go pricing.
Question 569
What is a feature of an Azure virtual network?
A. resource cost analysis
B. packet inspection
C. geo-redundancy
*D. isolation and segmentation
Explanation
Implement network segmentation patterns on Azure.
A unified enterprise segmentation strategy guides technical teams to consistently segment access using networking, applications, identity, and any other access controls. Create segmentation in your network footprint by defining perimeters.
The main reasons for segmentation are:
- The ability to group related assets that are a part of (or support) workload operations.
- Isolation of resources.
- Governance policies set by the organization.
Question 570
Select the answer that correctly completes the sentence.
________________ enables Azure resources to be deployed close to users.
A. Elasticity
*B. Geo-distribution
C. High availability
D. Scalability
Explanation
Because of geo-distribution you can deploy apps and data to regional datacenters around the globe, thereby ensuring that your customers always have the best performance in their region.
