Which two statements are true when comparing the SSH, HTTP, and WebSocket interfaces of a Cisco Collaboration device? (Choose two.)

Question

Options

• AThe SSH interface supports XML payloads only.
• BThe SSH, HTTP, and WebSocket interfaces support JSON and XML payloads.
• CThe HTTP interface supports JSON and XML payloads.
• DCommunications can be encrypted for all SSH, HTTP, and WebSocket interfaces.
• EThe WebSocket interface supports JSON payloads only.

• A
  6% (1)
• B
  88% (15)
• C
  6% (1)

Explanation

All three interfaces on Cisco Collaboration devices (SSH, HTTP, WebSocket) support both JSON and XML payloads, making B correct - there is no restriction to a single format on any interface. D is correct because all three can operate over encrypted channels: SSH is encrypted by design, HTTP upgrades to HTTPS via TLS, and WebSocket upgrades to WSS (WebSocket Secure) via TLS.

Why the distractors are wrong:

• A is false because SSH is not limited to XML - it supports JSON as well.
• C is technically a true statement in isolation, but it is incomplete: it only describes the HTTP interface, whereas B correctly captures all three interfaces together, making C the inferior (and therefore incorrect) choice.
• E is false because WebSocket supports both JSON and XML, not JSON exclusively.

Memory tip: Think "All Equal, All Encrypted" - all three interfaces are equal in payload support (JSON + XML), and all three can be encrypted (SSH natively, HTTP→HTTPS, WebSocket→WSS). Any answer that restricts one interface to a single format or denies encryption is automatically wrong.
