Hi,
The whole scenario is only talking about uploading:
“An advertisement company has a NodeJS application that is hosted across multiple EC2 instances and has incoming traffic balanced by an Application Load Balancer. The web application allows the clients to upload their high-resolution advertising media files which are stored to EC2 instances. Each instance stores the files and a background task synchronizes the data between other EC2 instances. Due to the growth of the company, the synchronization task can no longer cope with the high number of files being uploaded.”

Hi,
you also need to visit the instructions ‘test’ (first one in the lesson) to get a strike-through of the complete section

Hi Kenneth,
Seems the scenario is not yet updated in your question bank rite?
As I just came across it again.

In the answer there is also mention of a read replica
“start the replication from the Amazon RDS Read Replica.”
Where is the read replica involved?

I understood the setup is like:
– create the IPSec VPN between AWS and on-premise
– configure an on-premise MySQL instance
– create mysqldump on AWS RDS MySQL QDB Instance
– import mysqldump into on-premise MySQL instance (as ‘initial load’)
– start replication from AWS RDS MySQL DB Instance to on-premise MySQL instance via the IPSec VPN

Please confirm my understanding is correct.
Thanks,
Robert

Same issue here, but in review mode of a timed test (SA pro test 1), right after I finished the test.
For some incorrect answers (#5,64 and 73), no details are shown, that is no explanation, and it is also not indicated which is the correct answer….
Also in the dashboard there’s no statistics shown (yet).
I can provide screenshot.

Hi Farris-Kerai,
Just did the AWS $40 practice exam (I still had a voucher!).
You get 20 questions with a time limit of 90 minutes. It’s like the real exam (interface wise) but without proctor of course. Good if you have never done an AWS exam I guess, to experience the interface and a little bit of time pressure.
The complexity level of questions is similar to Dojo I would say. Not overly complex, only 2-3 long worded questions, mostly as Jon mentioned it’s about picking a combination of services.
I had some questions were I was in doubt, and I just scored 80%, but you only get a breakdown over the categories in your result score, not on the individual questions, and there’s also no explanation….so the learning effect is rather limited I would say…

Cheers,
Robert

Hi Farris-Kerai,

Yes I used ACG also. The study material is OK and reasonably up-to-date (contrary to some of their associate level course material), but high-level only, quizzes are OK, the exam I tried yesterday was very very though…I only scored 56%…
Partly there were some subjects I didn’t know about, so that was fine, partly due to time pressure I made some stupid mistakes (ouch), but also some of the questions seem rather not-up-to-date, so the as correct marked answer was a bit doubtful. Also with some of the (very brief) explanations I didn’t agree, plus there were quite a few (way too) long worded questions, which are very hard to answer correctly anyway in a few minutes in an exam setting.

Cheers,
Robert

Congratulations!
Yes, will soon do the timed mode tests.
I was doing the review mode already with a timer on my mobile phone set at 02:10 per question. I requested the ESL accommodation also, which is another 24 sec extra per question!
As long as the question are not all the long worded once type, it should be fine though.
Best regards,
Robert

@james
For the Review mode tests I scored 76%, 90% and 2x 80%.

Review mode is not my ideal mode, as I drop out of ‘the zone’ all the time, so made some stupid mistakes. I.e. score should be better…and I have some questions/feedback/different opinions on some questions…some forum posts coming up soon (@jon!)

I however choose this mode first, as I did some timed test from another vendor end of last year (I bought those tests), and there I only scored 65% (due to a lot of detail questions)…this was the trigger for me to do my ‘missing’ associate + security exams first, as this should give me a better basis for the SA pro tests. So I’m curious how much better I will do those other vendor tests in the rerun.

You might consider to additionally take some questions that you can find online -albeit without proper explanations as done here @ tutorials dojo, and sometimes the right/best option is undecided/no consensus-; I personally find them more difficult.

Next week I’m planning to do an exam from another vendor, which I heard is more difficult then the real exam, so let’s see how that goes.

I didn’t book my SA pro exam yet, as I want to have more confidence first in my capabilities. But I also plan todo it next month.

Cheers,
Robert

Hi Jon,

Thanks for your elaborate answer.

Maybe I should have given a bit more background.

I have read the SA pro exam ‘is the most difficult AWS exam’/’really need to prepare’/blablabla, and now I’m doing your tests -which for the associate exams I did recently were indeed a very good preparation/reflection of the real exam-, but now find the SA pro questions relatively ‘easy’ (that’s what I mean with ‘not challenging’ (to me), nothing negative about your tests, don’t get me wrong please).

So I’m a bit surprised, but at the same time also (a lot) relieved!

Good to hear you feel that your tests are not too far off to the topics on the real exam, and that there will also be short worded questions; I was also very worried about the time management…a long question easily takes you 4 minutes if you read everything fully, but if you just scan it, you might miss important details….

Nevertheless, other preparation tests I have taken/are taking, I feel are more of a challenge to me. Partly this has maybe to do with the (lack of proper) wording, so that in the end it’s not clear which (often of 2 left options) is the right/best choice. I will continue with these tests also, as it also fun and you always learn something new; it just takes more time.

I didn’t do SAP-C00.
300 unique questions, no problem (I thought 4 tests + final test each @75 questions, so in total 375 questions, but not all unique then)

Best regards,

Robert

Just tagging along here.
I’m using Chrome, and use the extension ‘The Great Suspender’, which reduces Chrome’s memory footprint in case you open up many tabs (by ‘moving’ a tab to disk thus freeing memory I assume).
If this happens when I left the browser tab unused in Quiz Review Mode for a while, upon the Reload (‘activate’ the tab again) from The Great Suspender, I loose the Review Mode status -at which question I was-, and end up at the beginning ‘Start quiz’ again.
Not a bug at tutorials dojo, just a note! Might be related to what Rodrigo was experiencing.
I whitelisted this url/domain already from suspending, so shouldn’t happen anymore.
Cheers,

Hi,
With limited I meant I encountered only 1 scenario regarding ACM-PCA in Tutorials Dojo, but in one Whizlabs test exam there were 5 or 6, which were more challenging as well (which forced me to read up about it!). But then as mentioned, in the actual exam there was no question about it at all. I suggest to check it out a bit though, just in case.
BR,
Robert

[kung]

forgot to mention that I used ACG for the theory (also did their quizzes and their exam simulator [crashed once after submitting the test…]), whizlabs tests (half of them had very bad English and half of the questions only have very limited explanations, but they did address some areas which were limited in dojo, like ACM-PCA and more complicated AD/SAML)

Hello Jon,

Thanks for the exhaustive reply.

They key sentence in your reply to me is

“RDS Encryption is using KMS to manage the encryption keys. The data must be written to storage first before RDS can do start the encryption. Hence, it encrypts the data AFTER it is written to storage, which is the exact opposite of what TDE is doing.”

As this is answering my question “Does this mean the data is first written unencrypted to storage, and then at a later time only encrypted while it is already on the storage (and this all transparently of course)?”

Apparently it is, although I could very well image that it would be a kind of streaming (in-memory) operation: the API call to write/put data to the database, which would then be streamed to an encryption API call, after which it would be written to storage.

Do you have any AWS documentation links about these technical details?
Would be interesting. I couldn’t find anything (yet).

Thanks,
Robert

ah indeed, overlooked that. thanks!
