Question 7

Harry is accessing a public cloud portal to add three additional web servers to the load-balanced feet. What type of cloud service enables him to perform this operation?

Answer 7

On-demand

On demand cloud services allow the cloud customer to access a self-service portal and instantly create additional servers, storage, processing power, or any other services as required.

Question 8

Erica created a company account on a public cloud and is configuring a MySQL database. What type of cloud service did she implement?

Answer 8

SaaS

Question 9

For redundancy, what are public clouds divided into?

Answer 9

Regions

Large cloud operations will actually partition operations into regions for fault tolerance and to offer localized performance advantages

Question 10

Liza works for a court recording firm that wants to store its records in the cloud with a specially developed application. A new cloud provider offers this service to all recording companies. What type of cloud model is this?

Answer 10

Community

Question 11

Tip of the Hat coffee company has deployed a custom cloud that is for their exclusive use. What type of delivery model did it deploy?

Answer 11

Private

Question 12

Dawn is a database administrator for her company’s cloud operations. She has created three read replicas in different availability zones and has selected a replication type that does not slow down the primary replica and has eventual consistency. What type of replication did she select?

Answer 12

Asynchronous

Question 13

Chuck wants to migrate an internally developed application the public clouds. The application runs on the Linux operating system. However, Chuck would prefer that the cloud provider take responsibility for all operating system maintenance. What type of cloud service would you recommend?

Answer 13

PaaS

Question 14

When architecting a database server migration, Herb is working to properly size the virtual servers he is implementing. What virtual pool should he focus on to make sure there are no write latencies to the database?

Answer 14

Storage

Question 15

What technology enables the widespread deployment of cloud offerings?

Answer 15

Automation

Question 16

The public cloud provider has ultimate responsibility for the integrity of your storage data. True of false?

Answer 16

False

Question 17

The establishment of average usage over time is the data that gets collected for what type of cloud reporting?

Answer 17

Baseline

Baseline collect data and provide trend analysis and capacity utilization information measured over time to determine average or expected metrics of a service in normal operation. Establishing baselines is helpful when you need to determine the size of the virtual machines required when migrating servers to the cloud.

Question 18

Lynn is documenting the maintenance responsibilities between her company and its public cloud provider. She notices that the cloud provider takes responsibility for all operating system updates and patches, and she needs to assume responsibility for the applications and services running on the operating system. What type of service model is she operating under?

Answer 18

PaaS

Platform as a Service (PaaS) offers the compute and operating system as a service and allows customers to install their applications on the cloud platform

Question 19

Darian is developing a cross-cloud provider migration report as part of his company’s business continuity plan. As he assesses the feasibility of migrating applications from one public cloud provider to another, what does he find is the service model that has the most lock-ins and is the most complex to migrate?

Answer 19

SaaS

The consumer does not manage or control the underlying cloud infrastructure but has control over operating systems, storage, deployed applications; and possibly limited control of select networking components (e.g., host firewalls).

Chapter 1 (page 9)

Question 20

Cloud capacity consumption can be measured by comparing current usage to what?

Answer 20

Baseline

Establishing baselines is helpful when you need to determine the size of the virtual machines required when migrating servers to the cloud. Baseline also are used to determine what is out of normal operations. You can use your baseline statistics as a reference, and if a counter has a variance above or below that value, it will be considered a serious issue.
