2.2 Summarize virtualization and cloud computing concepts

Question 1

Performing processing and storage elsewhere, over a network connection, rather than locally. Thought of as internet based computing.

Answer 1

Cloud Computing

Question 2

Cloud deployment models

Answer 2

IaaS
PaaS
SaaS
XaaS
Public
Community
Hybrid

Question 3

The idea of using storage capacity provided by a cloud vendor as a means to host data files for an organization. Can be used as a form of backup or support for online data services.

Answer 3

Cloud storage

Question 4

A cloud provider concept in which security is provided to an organization through or by an online entity.

Answer 4

SECaaS (Security as a service)

Question 5

Cloud service providers (CSPs) are the companies that operate a cloud service.

Answer 5

Cloud Service Provider

Question 6

Managed service provider (MSP) and managed security service provider (MSSP) are services that provide remote oversight and management of on-premises IT or cloud IT.

Answer 6

Manage security service provider (MSP/MSSP)

Question 7

Computing that relies upon sensors, IoT devices, or even edge computing devices to collect data and then transfer it back to a central location for processing.

Answer 7

Fog computing.

Question 8

In edge computing, the intelligence and processing are contained within each device. The architecture of edge computing performs computations closer to the data source, which is at or near the edge of the network.

Answer 8

Edge computing.

Question 9

A thin client is a computer with low to modest capability or a virtual interface that is used to remotely access and control a mainframe, virtual machine, or virtual desktop infrastructure (VDI).

Answer 9

Understand thin client.

Question 10

Application cells or application containers are used to virtualize software so they can be ported to almost any OS.

Answer 10

Understand application cells/containers.

Question 11

Microservices are an emerging feature of web-based solutions and is a derivative of service-oriented architecture (SOA). SOA constructs new applications or functions out of existing but separate and distinct software services.

Answer 11

Understand Microservices./ API

Question 12

Infrastructure as code is a change in how hardware management is perceived and handled. Instead of seeing hardware configuration as a manual, direct, hands-on, one-on-one administration hassle, it is viewed as just another collection of elements to be managed in the same way that software and code are managed under DevOps.

(Page 151).

Answer 12

Understand infrastructure as code.

Question 13

Software-defined networking (SDN) is a unique approach to network operation, design, and management. SDN aims at separating the infrastructure layer (hardware and hardware-based settings) from the control layer (network services of data transmission management).

Answer 13

Understand SDN.

Question 14

Software-defined visibility (SDV) is a framework to automate the processes of network monitoring and response. The goal is to enable the analysis of every packet and make deep intelligence-based decisions on forwarding, dropping, or otherwise responding to threats.

Answer 14

Understand SDV.

Question 15

Serverless architecture is a cloud computing concept where code is managed by the customer and the platform (i.e., supporting hardware and software) or server is managed by the CSP.

Answer 15

Serverless architecture.

Question 16

Services integration, cloud integration, systems integration, and integration platform as a service (iPaas) is the design and architecture of an IT/IS solution that stiches together elements from on-premises and cloud sources into a seamless productive environment.
.

Answer 16

Services integration.

Question 17

Resource policies are used to manage the use of cloud resources, which in turn reduces wasted spending on unnecessary cloud costs. Resource policies can define what resources are provisioned, where that takes place, and who is able to trigger and use those resources.

Answer 17

Resource policies.

Question 18

A transit gateway establishes a simple and seamless integration of virtual private clouds (VPCs) and local systems through a central hub or cloud router.

Answer 18

Transit gateway.

Question 19

Virtualization technology is used to host one or more OSs within the memory of a single host computer. Related issues include snapshots, patch compatibility, host availability/elasticity, security control testing, and sandboxing.

Answer 19

Virtualization.

Question 20

The hypervisor, also known as the virtual machine monitor (VMM), is the component of virtualization that creates, manages, and operates the virtual machines.

Answer 20

Understand hypervisors. (VM)

Question 21

A type I hypervisor is a native or bare-metal hypervisor. In this configuration, there is no host OS; instead, the hypervisor installs directly onto the hardware where the host OS would normally reside.

Answer 21

Type I hypervisor.

Question 22

A type II hypervisor is a hosted hypervisor. In this configuration, a standard regular OS is present on the hardware, and the hypervisor is then installed as another software application.

(Page 152).

Answer 22

Type II hypervisor.

Question 23

VM sprawl occurs when an organization deploys numerous virtual machines without an overarching IT management or security plan in place. To prevent or avoid VM sprawl, a policy must be established and enforced regarding the procedure for developing and deploying VMs.

Answer 23

Comprehend VM sprawl avoidance.

Question 24

VM escaping occurs when software within a guest OS is able to breach the isolation protection provided by the hypervisor to violate the container of other guest OSs or to infiltrate a host OS.

Answer 24

Understand VM escaping.
