C imo, symmetric encryption usually happens after the session keys are securely shared, not out-of-band.

B imo, because symmetric cryptography is way faster for encrypting large amounts of data, while asymmetric handles the initial secure handshake and key exchange. The combo balances speed and security.

Maybe B makes the most sense since asymmetric is too slow for data but great for exchanging keys securely, which symmetric then uses for fast encryption. Options A, C, and D don’t really fit how SSL/TLS typically works.

Option B also stands out because asymmetric is too slow for bulk data, so it’s mainly for key exchange.

It’s B. The question is about the advantage of using both types, and asymmetric crypto is definitely slower but perfect for securely exchanging keys, which then lets symmetric crypto handle the fast data encryption. Option A is off because symmetric algorithms don’t act as a fallback for asymmetric failures. C is wrong since symmetric keys aren’t sent out-of-band, they’re established through the handshake. D doesn’t quite fit either because it’s about performance, not device support specifically. So B nails the key point: asymmetric handles secure key exchange despite being costly compared to

True, asymmetric cryptography is slower but essential for secure key exchange without prior secrets. So option B fits well since it highlights the cost and key negotiation role. B

B symmetric is way faster for data encryption, asymmetric just for secure key exchange.

Totally agree, B fits best here. Asymmetric crypto is way slower, so it’s not practical for bulk data encryption. But it’s great for safely exchanging keys that symmetric encryption then uses to handle the rest quickly. The other options don’t really match how SSL/TLS works in practice.

B/C? B makes sense for key exchange speed, but C seems off since symmetric keys aren’t really sent out-of-band, they’re usually established during the handshake. So B feels more accurate here.

B tbh, asymmetric is slower but perfect for the initial key exchange, while symmetric handles the heavy lifting fast during the actual data transfer. Makes the whole process efficient.

Probably B since asymmetric is known to be slower but good for key exchange.
