Question 1

Broad network access,measured service,resource pooling,and rapid elasticity are essential characteristics of ___________.

Accepted Answer

Broad network access, measured service, resource pooling, and rapid elasticity are essential characteristics of cloud computing. PaaS (Platform as a Service) is a specific type of cloud computing service that provides a platform for developing, testing, and deploying software applications. Network access control refers to the process of controlling access to a network or specific resources within a network. EAP-TLS (Extensible Authentication Protocol-Transport Layer Security) is a security protocol used in wireless networks for authentication. None of these options fully align with the essential characteristics listed in the question.

Question 2

A _________ is an entity at one end of a point-to-point LAN segment that seeks to be authenticated by an autheticator attached to the other end of that link.

Accepted Answer

The answer of A _________ is an entity at one...

Question 3

_________ enables customers to combine basic computing services,such as number crunching and data storage,to build highly adaptable computer systems.

Accepted Answer

IaaS or Infrastructure as a Service is a model that provides basic computing resources such as processing power, storage, and networking capabilities to customers. Customers can use these resources to build their own customized computer systems, making it highly adaptable to their specific needs. Thus, IaaS enables customers to combine basic computing services for building their own computer systems.

Question 4

A __________ provides a form of NAC by allowing or denying network traffic between an enterprise host and an external user.

Accepted Answer

The answer of A __________ provides a form of NAC...

Question 5

_________ saves the complexity of software installation,maintenance,upgrades,and patches.

Accepted Answer

SaaS (Software as a Service) saves the complexity of software installation, maintenance, upgrades, and patches as all of these tasks are handled by the service provider. IaaS (Infrastructure as a Service) provides virtualized computing resources like storage and networking, but still requires software installation and management by the user. EAP (Extensible Authentication Protocol) is a security protocol used for wireless networks and DHCP (Dynamic Host Configuration Protocol) is a network protocol used for assigning IP addresses to devices on a network.

Question 6

NIST defines three service models,which can be viewed as nested service alternatives: software as a service,platform as a service,and _________ as a service.

Accepted Answer

The answer of NIST defines three service models,which can be...

Question 7

An __________ is a server computer that negotiates the use of a specific EAP method with an EAP peer,validates the EAP peer's credentials,and authorizes access to the network.

Accepted Answer

The answer of An __________ is a server computer that...

Question 8

A _________ in an intermediary that provides connectivity and transport of cloud services from CP's to cloud consumers.

Accepted Answer

The answer of A _________ in an intermediary that provides...

Question 9

In effect,________ is an operating system in the cloud.

Accepted Answer

PaaS stands for Platform-as-a-Service, which is a cloud computing model where a provider offers a platform for customers to develop, run, and manage applications without the complexity of building and maintaining the infrastructure typically associated with developing and launching an application. As such, PaaS can be considered an operating system in the cloud. The other options (IEEE 802.1X, IaaS, and DHCP) relate to networking protocols and infrastructure services, but do not directly relate to an operating system in the cloud.

Question 10

The ___________ functions as an access control point for users in remote locations connecting to an enterprise's internal network.

Accepted Answer

The answer of The ___________ functions as an access control...

Question 11

With a _________ infrastructure,the cloud infrastructure is made available to the general public or a large industry group and is owned by an organization selling cloud services.

Accepted Answer

A public cloud infrastructure is owned by an organization providing cloud services and is available for use by the general public or a large industry group.

Question 12

_________ is the provision of security applications and services via the cloud either to cloud-based infrastructure and software or from the cloud to the customers' on-premise systems.

Accepted Answer

SecaaS (Security-as-a-Service) is the provision of security applications and services via the cloud either to cloud-based infrastructure and software or from the cloud to the customers' on-premise systems. IaaS, PaaS, and SaaS refer to different cloud service models for providing infrastructure, platform, and software respectively, but do not specifically focus on security services.

Question 13

__________ methods are the actions that are applied to ARs to regulate access to the enterprise network.

Accepted Answer

The answer of __________ methods are the actions that are...

Question 14

With a ________ infrastructure,the cloud infrastructure is a composition of two or more clouds that remain unique entities but are bound together by standardized or proprietary technology that enables data and application portability.

Accepted Answer

The answer of With a ________ infrastructure,the cloud infrastructure is...

Question 15

___________ includes people,processes,and systems that are used to manage access to enterprise resources by assuring that the identity of an entity is verified,and then granting the correct level of access based on this assured identity.

Accepted Answer

The answer of ___________ includes people,processes,and systems that are used...

Question 16

_________ is a model for enabling ubiquitous,convenient,on-demand network access to a shared pool of configurable computing resources that can be rapidly provisioned and released with minimal management effort or service provider interaction.

Accepted Answer

The answer of _________ is a model for enabling ubiquitous,convenient,on-demand...

Question 17

A ________ is a person,organization,or entity responsible for making a service available to interested parties.

Accepted Answer

A cloud provider is responsible for providing services to interested parties. They are responsible for maintaining the infrastructure, security, and maintenance of the cloud services they provide. Cloud brokers help organizations select the best cloud services for their needs, but they are not responsible for making the services available. Cloud auditors verify the security and compliance of cloud services, but they do not provide the services themselves. Cloud carriers provide the physical infrastructure for cloud services, but they are not responsible for providing the actual services.

Question 18

With a _________ infrastructure,the cloud infrastructure is shared by several organizations and supports a specific community that has shared concerns.

Accepted Answer

A community cloud infrastructure is shared by several organizations who have shared concerns such as regulatory requirements or security concerns. Therefore, it is the best choice for the given scenario. Public cloud infrastructure is available to the general public, private cloud infrastructure is solely dedicated to one organization, and hybrid cloud infrastructure is a combination of both public and private clouds.

Question 19

A _________ is a person or organization that maintains a business relationship with,and uses service from,cloud providers.

Accepted Answer

A cloud consumer is a person or organization that maintains a business relationship with, and uses service from, cloud providers. Cloud auditors are responsible for auditing and verifying the performance of cloud services. Cloud brokers act as intermediaries between cloud providers and cloud consumers to help consumers find and choose the best services for their needs. Cloud carriers are telecommunications companies that provide the infrastructure and connectivity for cloud services.

Question 20

A ________ is a party that can conduct independent assessment of cloud service,information sytem operations,performance,and security of the cloud implementation.

Accepted Answer

A cloud auditor is specifically responsible for conducting independent assessments of cloud service, information system operations, performance, and security. Cloud carrier refers to the provider that operates the infrastructure and offers cloud services, and cloud broker is an intermediary between cloud service providers and consumers. Therefore, option A is the best choice.
