Google Compute Engine

Question 1

GCE

Answer 1

GCE is a purely Infrastructure as a Service (IaaS) solution, therefore, you will need to manage and scale your VM as necessary, but this makes it an ideal solution for lift and shift migration from on-premises into the public cloud.

Question 2

IaaS

Answer 2

Infrastructure as a service (IaaS) is the on-demand availability of highly scalable computing resources as services over the internet. It eliminates the need for enterprises to procure, configure, or manage infrastructure themselves, and they only pay for what they use.

Question 3

RDP

Answer 3

RDP (short for Remote Desktop Protocol) allows us to connect to another Windows server over a network connection.

Question 4

Bastion Host

Answer 4

A bastion host is a special-purpose computer on a network specifically designed and configured to withstand attacks, so named by analogy to the bastion, a military fortification. The computer generally hosts a single application or process, for example, a proxy server or load balancer, and all other services are removed or limited to reduce the threat to the computer. It is hardened in this manner primarily due to its location and purpose, which is either on the outside of a firewall or inside of a demilitarized zone (DMZ) and usually involves access from untrusted networks or computers. These computers are also equipped with special networking interfaces to withstand high-bandwidth attacks through the internet.

Question 5

Terminal Servers

Answer 5

Bastion Host

Question 6

Region

Answer 6

Regions are geographical locations that are made up of one or more zones.

Question 7

Zone

Answer 7

All zones in a region are connected through fast networking—usually below 5 ms for a roundtrip between each zone.

Question 8

IOPS

Answer 8

Input/output operations per second is an input/output performance measurement used to characterize computer storage devices like hard disk drives, solid state drives, and storage area networks. Like benchmarks, IOPS numbers published by storage device manufacturers do not directly relate to real-world application performance.

Question 9

Application Images

Answer 9

Application images can be used if you require, for example, Microsoft SQL Server pre-installed on your Windows Server

Question 10

Custom Images

Answer 10

Custom images are available per project where an image has already been created from a boot disk.

Question 11

Labels

Answer 11

To group related resources, it can be beneficial to label your VM instances. This can help with organizing and filtering for billing and reporting. Labels work with key-value pairs and can be used, for example, to differentiate between projects, environments, and much more.

Question 12

Who can change a deletion protection flag on a VM

Answer 12

Only users who have compute.instance.create permissions can modify this flag to allow a protected VM to be deleted.
