What is the maximum permissible one-way network delay between Unified CCE servers and ECE servers?

Question

Options

• A80 milliseconds
• B120 milliseconds
• C240 milliseconds
• D300 milliseconds

• A
  90% (27)
• C
  7% (2)
• D
  3% (1)

Explanation

Option A (80 ms) is correct because Cisco's design requirements for Unified Contact Center Enterprise (CCE) and Enterprise Chat and Email (ECE) integration specify a maximum one-way network latency of 80 milliseconds - exceeding this threshold causes degraded real-time communication between components, leading to synchronization failures, dropped sessions, and unreliable agent routing.

Options B (120 ms), C (240 ms), and D (300 ms) are wrong because they exceed Cisco's published ceiling; higher latency values are sometimes associated with other Cisco products or general VoIP tolerances (e.g., 150 ms is a common VoIP one-way threshold), making them plausible distractors - but none apply to the CCE-ECE integration specifically.

Memory tip: Think "8-0 for CCE-ECE" - the two components share the letter E, and the limit is the tightest of the choices (80 ms), reflecting that chat/email real-time sync is stricter than casual browsing but less forgiving than you might assume for a non-voice workload.
