practice test

Question 1

cloud computing

Answer 1

the on-demand delivery of it resources and applications via the internet

Question 2

difference before and after aws

Answer 2

build data centers based on guessing what our maximum peaks might be

Question 3

benefit aws

Answer 3

access servers, databases, storage, and higher level app components in seconds
temporary, and disposable resources , free from inflexibility and constraints of a fixed and finite architecture

Question 4

how aws can make your work agile to learn and adapt

Answer 4

test often, patch quickly and respond to incidents at lightning speed are a large part of aws security
elastically to
changing market conditions. facilitates scalability, agility, and innovation
predeveloped services that can bequickly assembled as building blocks,
automate software delivery , and create security and compliance guardrails

Question 5

scalability

Answer 5

resize resources as necessary means scale down
, shrink and adapt consumption of services , and accomodate new strategic directions
scalable for high availability and dependability, providing tools to help wide range application

Question 6

three factor of influence agility :

Answer 6

• increasing speed
  
  • the ease of experimentation
  • cultivating a culture of innovation

Question 7

cost prohibitive

Answer 7

is like you have some data centers where your customers are in globe
aws have a global reach and new resources just by one click to develop in one minutes

Question 8

less time infrastructure means:

Answer 8

spin up servers in minute and shutdown servers when no need them or put them work for another means

Question 9

virtual and automatable resources means

Answer 9

quickly carry out comparative testing
means : different testing , storage, instance, and configuration
means : consistent template in develop, test, and productions with increasing levels of operational control

Question 10

agility ,

Answer 10

elastically also powerful force to scale resources
: quickly develop new apps, instantly scale up as workload grows, instant shutdown resources are no required
AWS flexible with few hours or 24/7
AWS auto scaling and balancing tools to scale up and down based on demand

Question 11

reliability means

Answer 11

architecture must have a well planned foundation that handles changes in demand , detect failures and automatically heals itself
acuire resources based on demang and mitigate disruptions.

Question 12

why aws can mitigate disruptions

Answer 12

aws place their datacenter locate to some and multiple isolated locations
every one datacenters comes with each redundant power, networking and connectivity, housed in separate facilities
in aws you can place resources like in multiple locations so one die other locations will not fails resources will still be available

Question 13

security aws is world class why ?

Answer 13

because they use state of art electronic surveillance and multi factor access control systems and staffed by trained security guards 24/7

Question 14

why aws trusted by many company

Answer 14

a broad set of gloval cloud services like IOT, tols, security, enterprise app
service hlp faster lower it costs and scalability

Question 15

availability zone

Answer 15

operate production application and database more
highly available tolerant, and scalable than one data center
fault tolerant means a system can remain operational even some component fails, high availability keep system functioning
and accessible , and downtime minimized without human intervention

Question 16

secutrity

Answer 16

they handle ownership including region and encryption and data residency requirements up to you
before it takes time for infrastructure security , now aws provides monitorign any wehere any time
