Thanks for your reply Carlo – that makes perfect sense in that case.

Hi Carlo,

Sorry for delayed reply. A DX connection is not encrypted. To achieve encryption, need to implement a site to site VPN with IPSec tunnels over a public VIF. This would then make it secure. I think really it’s the use of the word “secure”. It’s a dedicated line and if that line was tapped all data would be plaintext. Hence, not secure.

Right?

Thanks,

Claire

Hi Carlo,

Thanks for your reply. I can answer my own question now 🙂

It was Review Mode Set 1 – AWS Certified Developer Associate > Question 19 (see attached)

I understand how the formula in the rationale given is working (I got the answer right; I just didn’t follow the rationale).

It was best for me to consider a timeline: 1s = 10 invocations, 2 = 20, 3 = 30, 4 = 40, … , 10 = 100, and thereafter the formula roughly works out (as this is all averages in any case). Therefore,

= 10 invocations per second * 10 seconds average duration

= 100 concurrent executions (after 10 seconds…)

Thanks,

Claire

Apologies Kenneth 😃 I have been experiencing issues attached images to my posts so I don’t think it went on the first time. Hoping this works…
