Not sure about A, seems a bit off to me.

I had no idea Expressway-E could do that!

Wait, isn't it C? That sounds more accurate to me.
DA

Totally agree, A makes the most sense!

I think it's A. That's how it usually works.

I thought internal endpoints register with Expressway-C, but I'm confused about how the communication flow works between the two Expressways.

I feel like both Expressway-C and Expressway-E are in the DMZ, but I can't recall which one is responsible for notifying the other about incoming calls.
JO

I remember practicing a question similar to this, and I think Expressway-E is the one that sends the request to Expressway-C for incoming calls.
LA

I think Expressway-C initiates the communication with Expressway-E, but I'm not entirely sure if it's the outgoing request or the other way around.
LY
Lynelle

Based on my understanding, I think the correct answer is A. Expressway-C establishes an outgoing request to Expressway-E to enable the external Expressway-E to notify the internal Expressway-C of an incoming call.

I'm a bit confused by the options. I need to carefully read each one and visualize how the communication would work between the two Expressway components.

Okay, let me think this through. The key is understanding how the two Expressway components communicate to enable secure video calls between internal and external endpoints.

This question seems straightforward, but I want to make sure I understand the relationship between Expressway-C and Expressway-E before selecting an answer.

This question is as clear as mud. Maybe Cisco should consider renaming their products to something more straightforward, like 'Expressway A' and 'Expressway B'.

I'm just going to guess and say Option D. It's the only one that doesn't mention the Expressway-C establishing an outgoing request to Expressway-E.
GW
Gwenn

Yeah, Expressway-E and Expressway-C need to work together to ensure secure communication between internal and external video endpoints.
EL

Expressway-E and Expressway-C must communicate somehow for the internal and external calls to work.
RE

I think Option D is correct. It makes sense that the internal endpoints are registered to Expressway-C in the DMZ.
MO
Mozell

Hmm, this one's tricky. I'm going to go with Option B, since it mentions that internal endpoints are registered to Expressway-E in the DMZ, and Expressway-C will handle the calls on behalf of Expressway-E.
NO

It's great to see how Cisco's media traversal technology enables such secure communication. Option B really highlights the role of Expressway-C and Expressway-E in this process.
JA

Expressway-C and Expressway-E definitely work together to ensure secure communication between internal and external video endpoints. Option B explains that setup perfectly.
LU
Lucia

I agree, Option B seems to be the most logical choice. It's all about how the internal and external endpoints communicate through the Expressways.
MA
Martin

I think Option B is correct. Expressway-C and Expressway-E are in the same network, so it makes sense that Expressway-C will handle the calls for Expressway-E.
BR

I'm not entirely sure, but I think Option C might be the right answer. Expressway-E establishes an outgoing request to Expressway-C, enabling the Expressway-C in the DMZ to notify the internal Expressway-E of an incoming call from an external endpoint.
JO
Jolene

Expressway-C in the DMZ notifies the internal Expressway-E of incoming calls from external endpoints.
OC
Ocie

I believe Expressway-E sends a request to Expressway-C for incoming calls.
SH
Shawna

I think Option C is correct. Expressway-E initiates communication with Expressway-C.
FA

Option A seems to be the correct answer. Expressway-C establishes an outgoing request to Expressway-E, enabling the Expressway-E in the DMZ to notify the internal Expressway-C of an incoming call from an external endpoint.
AN
Annice

It's important for the internal and external endpoints to communicate securely through Expressway-C and Expressway-E.
MA
Ma

Yes, that's right. Expressway-C sets up the connection with Expressway-E in the DMZ.
LA
Laurel

I think option A is correct. Expressway-C initiates the communication with Expressway-E for external calls.
HO

That's an interesting point, Alesia. But I still think A makes more sense in terms of how the communication is established securely.
AL
Alesia

I disagree, I believe the answer is B. Both Expressway-C and Expressway-E are in the DMZ, so they can communicate directly.
HO
Howard

I think the answer is A. Expressway-C initiates the communication with Expressway-E for external calls.
