PostgreSQL certification (status: passed)

You can now get postgresql certification online for the associate and then the advanced for $200 each. I am not sure of the process.

Mongo certification (status: passed one test, will do the other someday)

UPDATE: Got the mongo dba certifcation. Now I want to get the dev one too.

I will be doing two things here. Listing the urls for sample tests and good reading material. And, setup step by step example of stuff to do to learn it.

NOTE: The mongodb certification exams are once a month. I highly recommend taking the free courses at https://university.mongodb.com/courses/catalog which will help with certification. Here's also a trick. The certification exams are $150. A class is thousands of dollars. Take it, fail it, learn what you were weak on, take it again. That's what I did for the MySQL certifications, but I usually passed them the first time. Out of 6 MySQL exams, I barely didn't pass one, studied it, and took it again. Much cheaper than thousands of dollars on courses. I will do the same for Mongo certifications, so we will see how I do on the exams. I have lots of previous Mongo experience, so that helps.

I will rate these links when I get done with them.

  • Mongo study guides (need to rate these two --- the videos and such)
    • https://university.mongodb.com/exam/C100DEV/2016_March/guide
    • https://university.mongodb.com/exam/C100DBA/2016_March/guide
  • http://www.brainmeasures.com/online/tests/2718/mongodb-test.aspx#qqq
    • http://www.menprojects.com/class_notes/EXAMS/brainmeasures_notes.txt
    • They try to get you to pay $50 for a lot of questions that were taken from the manual. But to give them credit the test is free and good practice. 
    • Register first. 
    • Take test, copy the image locally, copy the webpage of the test results locally. 
      • Don't buy certificate. I don't think $50 is worth. Good free test but not a great certification test. 
  • http://www.tutorialspoint.com/mongodb/mongodb_overview.htm
    • Good basic review. Go through and do all their examples. 
  • http://www.sanfoundry.com/1000-mongodb-questions-answers/
    • Good questions. I suggest to go over the questions and focus on topics you are weak at.
  • https://quizlet.com/32272213/mongo-flash-cards/
    • These aren't that great. 
  • Cheating -- not sure which tests these are for. Study what you don't know

----------------------------------------------
All of these steps below will be linked to a file. I havent started it yet as I am looking at the links above, but I will note when I start them and put in the link. 
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv EA312927
echo "deb http://repo.mongodb.org/apt/ubuntu trusty/mongodb-org/3.2 multiverse"\
 | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list
sudo apt-get update
#sudo apt-get install -y mongodb-org
sudo apt-get install -y mongodb-org=3.2.4 mongodb-org-server=3.2.4 mongodb-org-\
shell=3.2.4 mongodb-org-mongos=3.2.4 mongodb-org-tools=3.2.4
Step 1. Setup a standalone mongo on port 3000. 

Step 2. Setup 5 mongo node cluster on same machine. 3 config servers. 1 mongos. 

Step 3. Start practice stuff.

Other stuff
