Free Isaca Cybersecurity Audit Certificate Actual Exam Questions - Question 9 Discussion

Makes sense to pick C here. Asymmetric encryption is pretty slow compared to symmetric, so it's usually reserved for things like securely sharing symmetric keys rather than encrypting data directly. Options A and B would involve lots of data, which isn’t practical with asymmetric. D doesn't seem right either since symmetric keys—not asymmetric keys—are what get distributed using asymmetric encryption. So C fits best.

Actually, going with C makes the most sense here. Asymmetric algorithms are too slow for encrypting large amounts of data, so they’re mostly used to securely exchange symmetric keys, which then handle the bulk encryption. Options A and B don’t fit since these tasks rely on faster symmetric ciphers. And D is off because asymmetric keys don’t need distributing the way symmetric ones do. So C stands out as the practical use in real-world applications.

C, because asymmetric keys are too slow for bulk encryption tasks.

Probably C. Asymmetric algorithms are mainly for safely exchanging symmetric keys, not for encrypting large amounts of data or distributing their own keys. That’s the common use case.

Option C seems right because asymmetric methods handle key exchange securely, while symmetric algorithms take over for the heavy lifting in data encryption. It’s all about efficiency.

Makes sense to pick C since asymmetric algorithms are slower and usually not for bulk data, so their main job is getting symmetric keys to the right place safely. So yeah, C.

It’s C, mostly for distributing symmetric keys securely.
