What makes use of the cloud service concept known as infrastructure as a service (IaaS)?

Correct! Wrong!

IaaS is a service provided by Azure Virtual Machines. The virtual machine's configuration and all operating system configurations are the customer's responsibility. PaaS options include Azure App Services and Azure Cosmos DB. SaaS product Microsoft Office 365 is available.

What are the two most prevalent benefits of cloud computing? Each accurate response offers an entire resolution.

Please select 2 correct answers

Correct! Wrong!

Even when anything goes wrong, cloud-based apps may continue to offer a seamless user experience with no noticeable downtime. Your clients will always experience the greatest performance in their location thanks to the ability to deploy apps and data to regional datacenters all around the world. Applications in the cloud can scale both vertically and horizontally. You do not have physical access to servers in a public cloud architecture since the cloud provider manages them.

What benefit does cloud computing offer over on-premises installations?

Correct! Wrong!

Scaling more fast is made possible by cloud computing. Cloud computing does not include characteristics like owning your own CPUs or having complete access in the event of an internet outage. Unlike an on-premises implementation, working from numerous workstations is not unique to cloud computing.

What do the aspects of data replication, geo-distribution, and cloud-based backup services entail?

Correct! Wrong!

Data and code are kept safe during disaster recovery using services like geo-distribution, data replication, and cloud-based backup.

If you have servers that are physically situated in your company's on-site datacenter but move some of them to the cloud, which cloud deployment model are you using?

Correct! Wrong!

By enabling the sharing of data and applications between a public cloud and a private cloud, a hybrid cloud combines the advantages of both types of clouds.

____________ refers to expanding an application's capacity by adding extra virtual machines

Correct! Wrong!

By increasing instances of resources, such adding virtual machines to the setup, scaling horizontally increases computational capability. By increasing a virtual machine's RAM or CPU count, you can scale vertically to improve computation capacity. The capacity to quickly implement new apps and services is referred to as agility. When something goes wrong, high availability cuts downtime to a minimum.

Virtual networks fall under what category of cloud service?

Correct! Wrong!

You can lessen the expense and difficulty of managing a physical server and the infrastructure of its datacenter with the aid of IaaS. A component of the IaaS cloud service are virtual networks.

Automatically scaling a program to make sure it has the resources required to fulfill user demands is an example of _______.

Correct! Wrong!

Elasticity is the capacity to adjust resources as required, such as increasing them during peak business hours to make sure an application can meet demand and then lowering them during off-peak hours. The capacity to quickly implement new apps and services is referred to as agility. In the event of a failure, a service or application can still be accessed because to high availability. A service or program is made available through geo-distribution in a number of areas, usually close to your users.

What factors affect high availability in a public cloud environment?

Correct! Wrong!

SLAs for different services vary. Sometimes, different service tiers will offer a variety of SLAs, increasing or decreasing the claimed availability.

The Azure deployment and management service is _____________ .

Correct! Wrong!

Azure's deployment and management service is called ARM. You can create, update, and delete resources in an Azure subscription using the management layer it offers. After deployment, you can secure and arrange resources using management tools like access control, resource locks, and resource tags.

Azure SQL Database uses which cloud service model?

Correct! Wrong!

A PaaS database engine is Azure SQL Database.

Choose the response that fully completes the statement.

It's known as ____________ to expand the computing power of an app by adding RAM or CPUs to a virtual machine.

Correct! Wrong!

By increasing a virtual machine's RAM or CPU count, you can scale vertically to improve computation capacity. By increasing instances of resources, such adding virtual machines to the setup, scaling horizontally increases computational capability. In the event of a disaster, disaster recovery safeguards data and other assets. When something goes wrong, high availability cuts downtime to a minimum.

Which two deployment patterns place management of the operating systems that run the applications on the shoulders of the customers? Each accurate response offers an entire resolution.

Please select 2 correct answers

Correct! Wrong!

When using IaaS or an on-premises implementation, clients are responsible for managing the operating systems. In PaaS and SaaS implementations, access to the operating systems is not possible.

Choose the response that fully completes the statement.

An area is matched with another region in the same __________ in a region pair.

Correct! Wrong!

Each Azure region is paired with a neighboring region that is at least 300 miles distant and located in the same geographic area, such as the US, Europe, or Asia.

Choose the response that fully completes the statement.

_____________ is the rapid deployment and configuration of cloud-based resources in response to changing business requirements.

Correct! Wrong!

When you're agile, you can swiftly deploy and adjust cloud-based resources as your app's needs change. Scalability refers to the ability to modify a configuration by adding RAM, CPU, or complete virtual machines. Because cloud-based apps are elastic, you can set them up to use autoscaling so they always have the resources they require. Cloud-based apps with high availability can continue to offer a seamless user experience with no discernible downtime even when anything goes wrong.

Choose the response that fully completes the statement.
__________ is a region of Azure that contains physically distinct data centers.

Correct! Wrong!

Within an Azure region, availability zones are physically distinct datacenters. One or more datacenters with separate power, cooling, and networking make up each availability zone.
