Discuss Blockchain CBSA Exam Topic 1 Question 2

What is a logic gate in electronics and computer science?

AA logic gate usually takes in 2 inputs and gives out 1 output. The inputs and outputs are binary values, meaning they can be both 1 and 0.

BA logic gate usually takes in 3 inputs and gives out 2 output. The inputs and outputs are binary values, meaning they can be 1 or 0.

CA logic gate usually takes in 2 inputs and gives out 6 output. The inputs and outputs are binary values, meaning they can be both 1 and 0.

DA logic gate usually takes in 2 inputs and gives out 1 output. The inputs and outputs are binary values, meaning they can be 1 or 0.

Suggested Answer: D

A logic gate usually takes in 2 inputs and gives out 1 output. The inputs and outputs are binary values, meaning they can be 1 or 0. A XOR logic gate takes in 2 binary inputs and gives out a high output ONLY when the inputs are different. Meaning, if A and B are inputted to a XOR gate then the out C will be 1 ONLY when A is not equal to B.

I thought some gates could take more than 2 inputs though.

Arlette 12 months ago

Yup, 1 and 0 are the only options!

Wait, can a logic gate really have 6 outputs? Sounds off.

Telma 1 year ago

Totally agree, it's all about binary values!

A logic gate takes 2 inputs and gives 1 output, that's right!

Okay, let me think this through. The Integration Architect is recommending a remote system that will subscribe to a platform event in Salesforce. That sounds like the "Fire and Forget" pattern, where Salesforce publishes the event and the remote system consumes it. I feel pretty confident that's the right integration pattern for this use case.

Hmm, I'm not entirely sure about this one. I'm debating between options B and D. Test management tools could help track the evaluation process, but performance tools do seem more directly relevant to the question. I'll have to think this through a bit more.

Hmm, I'm a bit confused. Do we need to define a DNS record as well, or can the clients just use the IP address directly? I'm not sure if option B is necessary.

I feel like RF Spectrum could be a possibility, but I'm not completely confident that's where I would find mesh info.

Situation C seems straightforward, right? I think it relates to arrangements under Medicare+Choice that are exempt, but I'm not entirely sure how that interacts with the Stark laws.
