Q

Zones

A

Each cloud region can have multiple zones (also known as availability zones or AZ) which are typically distinct data centers with their own power, cooling, and networking resources.

Q

Data center

A

A huge warehouse or room containing cloud infrastructure equipment. These data centers contain pods and racks or standardized containers of computing resources such as servers plus storage and networking equipment.

Q

Serverless

A

Serverless computing resources are also available for users to run their workloads. They are considered an abstraction layer on top of VMs.

Q

Hypervisor

A
  • Software that runs above the physical server or host.

- They essentially pull the resources from the physical server and allocate them to a virtual environment.

Q

Dedicated Hosts

A

offer single tenant isolation

17
Q

Bare metal Server

A

It is a single tenant, dedicated physical server.
-The cloud provider takes the physical server and plugs it into a rack in a data center for customers. They manage the server up to the operating system. The provider is responsible for fixing hardware or rack connections.

18
Q

What are containers?

A

Containers are an executable unit of software in which application code is packaged, along with its libraries and dependencies, in common ways so that it can be run anywhere, whether it be on desktop, traditional IT, or the cloud.

19
Q

Reserved VMs

A

allow you to reserve capacity and guarantee resources for future Deployments.

20
Q

Which one of the following layers is considered the foundation of the cloud?

A

Infrastructure layer

21
Q

Which of the following isknown as distinct data centers with their own power, cooling, and networking resources?

A

Zones

22
Q

Which of the following are characteristics ofa region? Identify all that apply.

A

Has a name such as NA South or US East.
Is isolated from other regions, so if one was impacted by a natural disaster, the cloud operations in others would continue to function.
A geographic area or location where a cloud provider’s infrastructure is clustered.

23
Q

Which one of the following is a characteristic of both a bare metal server and a virtual server?

A

Provisioned with default storage in local drives.

24
Q

What is the function of a hypervisor?

A

Pulls resources from the physical server and allocate them to a virtual environment.

25
Q

What is another name given to a Type 2 hypervisor?

A

Hosted

26
Q

Virtual servers and virtual instances are two terms used synonymously in the IBM Cloud with which of the following?

A

Virtual Machines

27
Q

What type of server satisfies workload examples such as ERP, CRM, AI, deep learning and virtualization?

A

Bare metal

28
Q

VMware, ESXi, Microsoft Hyper-v, and open-source KVM are some examples of which Type of hypervisor?

A

1

29
Q

Which of the following is added to the network to enable users’ access to the application in the internet tier?

A

Public gateaway

30
Q

What is the main difference between deploying a network in an on-premises data center and deploying a cloud network?

A

Physical devices

31
Q

Portability, scalability, streamlined development and deployment of cloud-native applications and architectures are some of the advantages of which one of the following components?

A

Containers
