2.2 Summarize virtualization and cloud computing concepts.

Question 1

separates data and control planes in a network. It uses virtualization to route traffic to its intended destination, instead of using proprietary hardware.

Answer 1

Software Defined Network (SDN)

Question 2

offers a company configurable operating systems and applications to use in a cloud environment.

Answer 2

Platform as a Service (PaaS)

Question 3

full-service product and is pay as you go. It is accessed directly over the internet.

Answer 3

Software as a Service (SaaS)

Question 4

an environment that uses a mix of public, community, and private cloud concepts with a single management platform.

Answer 4

Hybrid Cloud

Question 5

provides companies the ability to “rent” hardware and services in a cloud environment

Answer 5

Infrastructure as a Service (IaaS)

Question 6

computing services offered either over the internet or within a private internal network.

Answer 6

Private cloud

Question 7

SECaaS

Answer 7

Security as a Service part of the Software as a Service (SaaS) platform. Any security services provided in the cloud are a subset of SaaS cloud-based technologies.

Question 8

vulnerability that enables a user to gain access to the primary hypervisor and associated virtual machines.

Answer 8

Virtual machine escape

Question 9

Virtualization sprawl

Answer 9

a phenomenon that occurs when the number of virtual machines (VMs) on a network reaches a point where the administrator can no longer manage them effectively. This can happen by patch mismanagement or simply too many virtual machines.

Question 10

What are the benefits of edge computing

Answer 10

Edge computing provides minimal latency due to the early processing of data closer to the data source versus the center of the network. This allows for faster data processing and content delivery to mobile devices.

Edge computing allows for Internet of Things (IoT) applications to use less bandwidth and operate normally under limited connectivity in order to meet 5G requirements.

Edge computing layers are high-value targets for cyber security events and data exfiltration attacks such as distributed denial of service attacks (DDOS), malware injection, and authentication.

Edge computing can become complex and expensive as demand and need grow.
