SAA Whizlabs Test 7 - Githubissues

Answer:

The answer I selected ended up being correct. The reason I chose this answer out of the other 4 was for a few reasons. The first being that the scenario required that the architecture wanted the components in the scenario to be highly available. The answer I selected met that crucial criteria. The first part was the 2 public subnet; that will allow access to the services and whatever they may be hosting for the clients in this scenario. They are most likely Class A Subnets to allow the most public access. The EC2 instances are placed across 2 AZ's, this will ensure that should one go down, the other will continue to provide the services needed to the clients should one go down. The same logic can be applied to the RDS and the NAT Gateway portion of the Architecture. All combined meet and slightly exceed the expectation of maintaining High Availability.

I genuinely misread this question. I first though CloudTrail, but there was no mention of "auditing" or "logging" so that ruled out CloudTrail. Next I though CloudWatch because of the word "resources" and assumed that the question was referring to CPU,RAM, bandwidth etc. The answer was clearly AWS Config. I don't know Config that well and it finally got me. I'll review AWS Config.

I go this one wrong. I didn't fully understand the full concept and the question. I chose answer B mostly out of desperation. I understood what AWS SSO was from the context of the question and knowing what "SSO" meant from previous experience with the acronym. So I guess I'll need to go over the question again.

I really though that this was a no brainer. I didn't fully acknowledge the presence of the MySQL DBS being mentioned or really think that it was relevant. Some more work on MySQL is needed; back to Linux Academy. I know that redundancy is crucial for all Cloud services; so chose that more as my "default answer." I have to stop doing that.

I got this one wrong strictly because of the wording of the question. It mentioned " even after the instances are terminated, the EBS volumes are critical to retain." So to me that meant that they are going to get deleted at some point regardless. I was hoping and thinking this would be an AMI solution since the data is "so important." So naturally I wanted to make a copy of this "crucial data" and clearly it was wrong. After reading the explanation I'm starting to understand more of why it was the wrong answer.

wdemp commented 5 years ago

This one was a real no brainer. There was really no other option on here that could have been correct if it didn't involve "logging." And the other options were obviously wrong. So no further analysis required on this one.

wdemp commented 5 years ago

I didn't think this one was going to be much of a challenge so I'm a little surprised that I got it wrong. I didn't really know about "context aware" or what it really meant. This was bad to miss considering I have had to use verification codes and they always go to email.

wdemp commented 5 years ago

I;m completely second guessing myself now with all the questions that I have been getting wrong. There is no valid excuse for missing this one; considering that I mentioned multi AZ or anything involving data redundancy is my default answer. I should have stuck to the default.

wdemp commented 5 years ago

This was bad because I haven't fully memorized the different EBS volumes. I'll write out the chart by hand this weekend.

wdemp commented 5 years ago

This one took a while to figure out; personally I feel lucky getting this one correct. But even with my limited knowledge and understanding of NAT I still felt this was the only answer that fit. Establishing a NAT Gateway would be the only way to make sure that the performance is increased.

wdemp commented 5 years ago

I'm actaully proud that I got this one right. I remembered details from our last session that helped. I might have chosen EC2 but couldn't remember a time when API was involved with it. I'll look more into that.

wdemp commented 5 years ago

There really is no explanantion needed here. I just needed to read the question and understand what was being asked.

wdemp commented 5 years ago

I'm pretty agitated that I missed this one considering how many times we went these types of scenarios. I kinda knew that A sounded too good to be true, but at the same time I thought D was going to work. I didn't even consider B an option.

wdemp commented 5 years ago

This was pretty bad. I looked at A and for some reason didn't choose it. It was obviously A and I know just enough about Security groups that it was correct.

wdemp commented 5 years ago

This was really bad, considering I was scrolling over A and didn't choose it. I think there is both over and under thinking going on today.

wdemp commented 5 years ago

You would have lost it if I didn't get this one correct.

wdemp commented 5 years ago

This one required a good amount of re-reading. The key to this was knowing that it was all about making sure that Aurora could communicate with Lambda and vice versa. Even though IAM was not mentioned in the question I knew that it was the only way that these 2 services were going to be able to communicate with each other and work properly.

wdemp commented 5 years ago

This was disappointing to get wrong. This should have been a no brainer, but it clearly wasn't. A was the only answer that involved S3 in the answer and that's the real reason I picked A. I assumed that it was important that S3 was involved in the answer.

wdemp commented 5 years ago

This one took more thought than it should have. I keep thinking these are trick questions. This one wasn't elaborate enough to be considered a trick question. The answer was in the question.

ravsau commented 5 years ago

Good! Keep on going. Maybe open an issue per question that you found difficult or challenging.

wdemp commented 5 years ago

This was a misreading and I should have read this one more throughly.

wdemp commented 5 years ago

I'm going to review what partition keys are. Can't remember at this time.

wdemp commented 5 years ago

It took me a second to remember from one of our sessions that the answer couldn't be 24 hours. This was due to getting a question like this one wrong a while back.

wdemp commented 5 years ago

It would have been really bad if I got this one wrong.

wdemp commented 5 years ago

I read this one too fast. The key words were: latency, read, requests, were a dead give away.
