Answer 1

Header(Algorithms Token Type)
Payload(Data)
Verify

Question 2

IDaaS

Answer 2

identity as a service a cloud based authentication built and operated by a third-party provider
companies supply cloud based authentication or identity
feature being delivered or served to a company through remote connection from a third-party provider
examples (google, facebook, linkedin , are all identity providers
ensure users are who they claim to be

Question 3

openAPI

Answer 3

ex: Swagger

Question 4

SDLC

Answer 4

Software Development Life Cycle
1  Gather Requirements
2 Analysis
3 Design
4 Development
5 Testing 
6 user acceptance testing
7 Release
8 Maintenance

Question 5

Waterfall

Answer 5

Pros: clear well defined steps
intuitive, doesn’t require specialized knowledge
clear and concrete end goal
allows for clean transfer of information from step to step

Cons: makes changes difficult always moving forward
excludes the client beyond the initial gather requirements phase
delays testing until completion, leaving potential problems unnoticed until the latter half of the project

Question 6

Agile

Answer 6

more of a concept that an actual methodology
You consistently communicate with the client and stakeholders about what they want in the project (little to no documentation)

Question 7

Scrum

Answer 7

Implementation of Agile concept
framework that helps teams work together
collaboration and helping each other to solve problems one person might have during a sprint
It consists of a series of sprints where each team has specific user stories to tackle

Question 8

KanBan

Answer 8

Event driven instead of time
KanBan boards involved
Allows use of specialist

Question 9

Scrumban

Answer 9

agile framework of Scrum and KanBan

Question 10

User Epics

Answer 10

Identify unique
~sets of users stories and combine them into epics
if multiple stories/use cases relate to a ‘manager’ user then they should be collected into the manager epic

ex : Revaturepro : user, trainer, and admin/manager account
user epic: creation of quiz, assigning quiz, taking quiz» all one user epic ‘Quiz’
scoring could be another example

Question 11

paired programming

Answer 11

process where paired programming is the process of two developer working on a specific piece of code or feature together
PILOT: the pilot is focused on the immediate needs of the code and is the one who writes it
approach falls into category of SDLC, (ex: waterfall, big bang, agile extreme programming)
NAVIGATOR: focuses on the bigger picture how it will fit in the greater project

Question 12

Velocity

Answer 12

rate in which your team is able to complete task
used in hand with story points; Velocity is “the number of story points completed in a sprint.” makes better long term planning for out projects

“Story points per hour”

Question 13

DevOp Methodologies

Answer 13

strategies for software development big bang waterfall and Agile

Question 14

Framework

Answer 14

specific implementations of methodologies

ex: scrum, kanban, and xp

Question 15

Difference ceremonies in scrum

Answer 15

standups, sprint review, and sprint retrospective

Question 16

PaaS

Answer 16

Platform As A service

Question 17

Saas

Answer 17

software as a service

Question 18

Docker

Answer 18

Package software into standardized units for development, shipment and deployment
pros: run on most things physical or virtual machine, data center, cloud providers, you can scale up or tear down application as business dictates(based on demand)
cons:

Question 19

Containerization

Answer 19

involved bundling an application together with the configuration files, libraries, and dependencies required (components to run)
when creating a container the allocation of resource is dynamic
uses as much resources need to run app

Question 20

Virtualization

Answer 20

creation of a virtual machine that stimulates a real computer with an operating system: the virtual machine, the allocation of resource is static. will only use whats needed gb of ram

Question 21

purpose of Docker

Answer 21

allows developers to work in standardized environments using containers
they can work with various development environment Java, .Net, Ruby etc with whatever OS; windows, Linux, Mac and still give app to everyone as long as they have a docker engine
perfect for CI/CD workflows and for scaling

Question 22

Docker Images

Answer 22

standalone packages that include everything for the application to run (code itself, dependencies, configuration etc
immutable(cant change) file and represents an application and its virtual environment at a specific point in time

Question 23

Docker container

Answer 23

image cant run on its own it needs a docker container to run the image

Question 24

Docker containers

Answer 24

Containers:
STANDARD Docker created the industry software standard for containers portability
LIGHTWEIGHT share the machines OS system kernel and don’t require an OS per system driving higher server efficiencies and reducing server and licensing cost
SECURE Applications are safer in containers and Docker provides the strongest default isolation capabilities in the industry

Question 25

Docker registry

Answer 25

server side or cloud application where you store your images and make it easy to distribute to everyone else
docker is like a GitHub for docker images

Question 26

Docker Ignore

Answer 26

like gitignore will ignore certain files in your application to not put inside of image

Question 27

Docker configuration

Answer 27

extra information to tell the docker container how to run the image we will only use default “its above my pay grade :)!”
