QUESTION: 9

In a cloud deployment, SaaS can stand for which of the following? (Select 2)

Stack as a Service '
Security as a Service
Service as a Service
Software as a Service

Answer(s): B,D

Explanation:

Security as a Service and Software as a Service are two examples of SaaS in a cloud deployment. Security as a Service is a model where security services such as firewall, antivirus, encryption, etc. are delivered over the Internet by a cloud provider1. Software as a Service is a model where software applications such as email, CRM, ERP, etc. are hosted and managed by a cloud provider and accessed by users over the Internet2. Stack as a Service and Service as a Service are not valid terms for SaaS in a cloud deployment. Stack as a Service is a typo for Stack Overflow, a popular online platform for developers3. Service as a Service is a redundant and meaningless term that does not describe any cloud service model4.

Cloud Ecosystem, Section 1.3: Cloud Service Models 3: Stack Overflow 4: What is Service as a Service (SaaS)?

SaaS within cloud computing primarily stands for Software as a Service, which delivers software applications over the internet on a subscription basis. It allows users to connect to and use cloud- based apps over the Internet, such as email, calendaring, and office tools (like Microsoft Office 365).

Security as a Service (SECaaS) is an outsourcing model for security management. Typically, businesses utilize this service for functions like anti-virus software, intrusion detection, and authentication. SECaaS is also considered a type of SaaS where security services are delivered remotely via the internet. Therefore, both Software as a Service and Security as a Service are correct answers, emphasizing the diversity of services provided through the SaaS model beyond just software applications.

The public cloud ecosystem is a great value for users that offers many more options and_____than the simple consumption of resources.

constraints
problems
operability
benefits

Answer(s): D

Explanation:

The most appropriate word to complete the sentence is benefits. The public cloud ecosystem offers many benefits to users, such as scalability, flexibility, cost-efficiency, and innovation12. Constraints, problems, and operability are not suitable words to describe the advantages of the public cloud ecosystem over the simple consumption of resources.

QUESTION: 11

Which of the following are AI hardware solutions? (Select 2)

DataLake
Habana
EyeQ
Sparks

Answer(s): B,C

Explanation:

Habana and EyeQ are two examples of AI hardware solutions that are designed to accelerate deep learning and computer vision applications. Habana is a company that produces AI processors for both training and inference workloads1. EyeQ is a family of system-on-chips (SoCs) developed by Mobileye for advanced driver-assistance systems (ADAS) and autonomous driving2. DataLake and Sparks are not AI hardware solutions. DataLake is a term that refers to a large-scale data storage architecture that can store structured, semi-structured, and unstructured data from various sources3. Sparks is a misspelling of Spark, which is an open-source distributed computing framework for large-scale data processing and machine learning4.

QUESTION: 12

Which of the following are characteristics of traditional monolithic services. (Select 2)

Low scalability
Very light weight application
Fixed capacity
Very fast deployment

Answer(s): A,C

Explanation:

The characteristics of traditional monolithic services are low scalability and fixed capacity. Monolithic services are applications that are built as a single unit, where all the components are tightly coupled and run in the same process. This makes them hard to scale, as they require more resources and coordination to handle increased demand. Monolithic services also have fixed capacity, as they are designed for a specific workload and cannot adapt to changing requirements or traffic patterns. Monolithic services are often slow to deploy, as they require updating the entire application for any change or improvement.

QUESTION: 13

Does the technology layer function support automated service delivery?

Yes
No

Answer(s): A

Explanation:

The technology layer function supports automated service delivery by providing the necessary tools and mechanisms to orchestrate, monitor, and optimize the cloud resources and services. The technology layer function consists of four sub-functions: cloud management, cloud orchestration, cloud automation, and cloud analytics. These sub-functions work together to enable the efficient and flexible operation of the cloud ecosystem.

QUESTION: 14

It is possible to run a cloud solution in a Single Node.

True
False

Answer(s): B

Explanation:

It is not possible to run a cloud solution in a Single Node. A cloud solution requires a minimum of three nodes to provide high availability, scalability, and fault tolerance1. A Single Node is a standalone server that does not have any redundancy or load balancing features2. A Single Node can be used for testing or development purposes, but not for production or deployment of cloud applications.

QUESTION: 15

Which of the following are properties related to a public cloud? (Select 2)

For users, there is no cloud infrastructure operation
An In-house solution
Easy scaling
O&A requirement
Very complex management

Answer(s): A,C

Explanation:

The properties related to a public cloud are for users, there is no cloud infrastructure operation and easy scaling. A public cloud is a cloud service that is offered by a third-party provider over the public internet, and is available to anyone who wants to use or purchase it1. Users of public cloud do not need to operate or maintain the cloud infrastructure, as it is the responsibility of the cloud provider2. Public cloud also offers easy scaling, as users can quickly and dynamically provision or release resources according to their needs2. Public cloud is suitable for applications that have unpredictable or variable demand, or that do not require a high level of security or customization3.

QUESTION: 16

Which of the following statements are correct regarding the characteristics of microservices? (Select 2)

Microservices are chained in order to build an application.
All functions are the same in microservices.
Monolithic applications breaks functions in small pieces called microservices.
Microservices are limited to 10 per application.

Answer(s): A,C

Explanation:

Microservices are a design principle for cloud-native applications, where each application is composed of a set of small, independent, and loosely coupled services that communicate with each other through well-defined interfaces1. Microservices have the following characteristics2:
Microservices are chained in order to build an application, meaning that they are connected by a network and exchange messages or data to perform a specific function or task. Microservices are differentiated by function, meaning that each microservice has a single responsibility and performs a distinct function within the application. Microservices are derived from monolithic applications, meaning that they are created by breaking down a large and complex application into smaller and simpler pieces that can be developed, deployed, and scaled independently.
Microservices are scalable and resilient, meaning that they can handle variable workloads and recover from failures without affecting the whole application. Therefore, the correct statements are A and C, while B and D are incorrect.
