I thought SHA-1 was 128 bits too, but I guess not!

CRC-32 is only 32 bits, not even close!

MD5 is the one that gives you a 128-bit hash!

I think MD5 is the right answer, but I also remember something about its vulnerabilities. It’s tricky!

I recall that SHA-1 and SHA-512 produce longer hashes, but I can't quite remember the exact lengths.

I’m not entirely sure, but I feel like CRC-32 might be related to checksums rather than a proper hash function.

I remember hashing algorithms from our last practice session, and I think MD5 is the one that produces a 128-bit hash.

Okay, let me think this through. CRC-32 is 32 bits, SHA-1 is 160 bits, and SHA-512 is 512 bits. That leaves MD5 as the only 128-bit option. I'm feeling confident about this one.

Hmm, I'm a bit confused on the differences between the hash algorithms. I'll need to review my notes to make sure I understand which one has a 128-bit output.

I'm pretty sure the answer is B. MD5 produces a 128-bit message digest, so that's the one that fits the description in the question.

I know MD5 has had some security issues, but I think that's still the right answer here based on the bit length requirement. I'll double-check my understanding, but I'm leaning towards B.

Ah, I see now. The "secondaryPreferred" tag is the one that specifies the operations to be read from the node with the least network latency. I think I've got it!

Okay, let's think this through. Creating a messaging policy sounds like a good start, but I wonder if there are any other settings or configurations we need to consider.

Hmm, I'm a bit unsure about this one. I know cash-to-cash cycle time and order-fill rate are important, but I'm not sure if they're the most appropriate for gaining a competitive advantage through supply chain reliability.

I've got a good feeling about this one. The electronic expansion valve is the more advanced and efficient option, so that's probably what Huawei is using in their precision air conditioning units.

Ah, I remember learning about this! I'm pretty sure the answer is that the information from the previous block is embedded into the current block through hashing. That's what creates the chain.
