Cloud

Question 1

Scalability

Answer 1

Handles the growing workload required to maintain good performance and efficiency for a given software or application

Question 2

Virtual Scaling (Scaling up)

Answer 2

Increasing the power of the existing resources in the working environment

Question 3

Horizontal Scaling (Scaling Out)

Answer 3

Adding additional resources to help handle the extra load being experienced

Question 4

Elasticity

Answer 4

Attempts to match the resources allocated with the actual amount of resources needed at any given point in time

Question 5

Platform as a Service (PaaS)

Answer 5

Somewhere between SaaS and IaaS. A typical PaaS solution would deploy servers and storage network infrastructure (as per IaaS) but also provide a multi-tier web application/database platform on top.

Question 6

Desktop as a Service (Daas)

Answer 6

Means of provisioning virtual desktop infrastructure (VDI) as a cloud service. VDI allows a client browser to operate an OS desktop plus software apps. This removes the need for an organization to deploy and maintain client PCs and software installs.

Question 7

What Is Infrastructure as Code?

Answer 7

Provisioning architecture in which deployment of resources is performed by scripted automation and orchestration. (cloud)

Question 8

Orchestration

Answer 8

Automation of multiple coordinated steps in a deployment process.

Question 9

Examples of host-based hypervisors

Answer 9

VMware Workstation
Oracle® Virtual Box
Parallels® Workstation.

Question 10

Type II hypervisor

Answer 10

Is itself installed onto a host operating system.

Question 11

Type I hypervisor

Answer 11

(bare-metal)
Installed directly onto the computer and manages access to the host hardware without going through a host OS.

Question 13

Network functions virtualization (NFV)

Answer 13

• A way to virtualize routers, firewalls, and load balancers
• Extract network functions from hardware they ran on
• Packaged as virtual machines (VMs)

Question 14

Virtual Network Function (VNF)

Answer 14

• Run as VMs on standard server platforms.
• Less epxensive and more flexible than specialized hardware
• Specifies and deploys instances of each virtual appliance
• Software implimentations of network functions

Question 15

NFV Infrastructure
(Virtual Network Function)

Answer 15

• Harware and virtual resources necessary for deploying, managing, and executing VNFs

Question 16

Management and Orchestration (MANO) vnf

Answer 16

• Oversees the lifecycle management of the VNFs
• Orchestrates the resources across the NFVI

Question 17

Fibre Channel

Answer 17

-High speed communications protocol for SANs.
-1 to 128GFC (Gbps)

Question 18

Channel over Ethernet (FCoE)

Answer 18

-Fibre Channel packets over Ethernet cabling
-Allowing for a mixed use Ethernet network with LAN and SAN
-Requires special 10/40/100G adapters that combine the function of NIC and HBA,
-San

Question 19

Internet Small Computer System Interface (iSCSI)

Answer 19

-SAN
-IP tunneling protocol that enables the transfer of SCSI data over an IP-based network
-Inexpensive alternative to Fibre Channel

Question 20

North-South traffic

Answer 20

Traffic that flows into and out of a data center.

Question 21

East-West traffic

Answer 21

Communication between the different components of a data center.

Question 22

Private Cloud

Answer 22

Systems and users only have access with other devices inside the same private cloud or system

Question 23

Community Cloud

Answer 23

Collaborative effort where infrastructure is shared between several organizations from a specific community with common concerns

Question 24

Virtual Machine (VM) Escape

Answer 24

Occurs when an attacker breaks out of one of the isolated VMs and begins to directly interact with the underlying hypervisor

Question 25

Infrastructure as Code (IaC)

Answer 25

Enables managing and provisioning of infrastructure through code instead of through manual processes

Question 26

Private-Direct Connection

Answer 26

Extends preexisting, on-premise data center into the provider's network to directly connect to your virtual private cloud network.

Question 27

Virtual Network Computing (VNC) Port 5900

Answer 27

*Designed for thin client *Virtual Desktop Infrastructure (VDI)

Question 28

Virtual Desktop Infrastructure (VDI)

Answer 28

Hosts a desktop environment on a centralized server

Question 29

Core Layer

Answer 29

*Cloud Three Tiered Hierarchy *Most powerful equipment *Merge geographically separate networks to one logical *Min of 2 routers in a redundant config

Question 30

Distribution/Aggregation Layer

Answer 30

*Cloud Three Tiered Hierarchy *Implement ACLs and filters *Define policies for network at large *L3 Switches

Question 31

Access/Edge Layer

Answer 31

*Cloud Three Tiered Hierarchy *L2 switches

Question 32

Software-Defined Networking (SDN)

Answer 32

Network centrally controlled, or programed, using software applications

Question 33

Application Layer | SDN

Answer 33

*Rsource request *Info about the network as a whole

Question 34

Control Layer | SDN

Answer 34

*Uses info from the applications and decides how to route a data packet *How traffic is -Prioritized -Secured -Forwarded to | Controls traffic

Question 35

Infrastructure Layer |SDN

Answer 35

*SDN *Contains devices that receive info about where to move the data and then move it *Can be physical and/or virtual

Question 36

Management Plane

Answer 36

*SDN *Monitor traffic and status
