Any BLE version won't cut it, only v4.2 has ECDH support.

I feel like any BLE version could potentially support ECDH, but I doubt that's accurate. I should double-check the specifics.

I practiced a similar question where BLE v4.2 was the answer for enhanced security protocols. Maybe that's the one?

I'm feeling pretty confident on this one. The question specifically mentions the ECDH cipher suite as a requirement, so the answer has to be one of the BLE versions that support that. I'll select B to be safe.

Okay, let me think this through. ECDH is an elliptic curve-based key exchange protocol, so it makes sense that the newer Bluetooth versions would support it for secure communications. I'll go with B as my best guess.

Hmm, I'm a bit confused on this one. I know ECDH is a cipher suite, but I'm not sure which Bluetooth versions support it. I'll need to review the Bluetooth specifications to be sure.

I'm pretty sure the answer is B. BLE v4.2 supports ECDH, which is a requirement for this IoT security implementation.

Okay, let me break this down. Periodic testing and revision of contingency plans - that sounds like it's asking about the process of maintaining and updating those plans, so I'm going to go with A. Testing and Revision Procedures.

Bluetooth versions and their cipher suites? Now that's what I call a party trick! B is the answer, but I'm more impressed by your ability to make this sound exciting.

Wait, is ECDH the same as Elliptic Curve Digital Signature Algorithm (ECDSA)? I'm a bit confused, but I think B is the right choice.
