In the Cisco UCCE with CVP centralized deployment with single data center, which statement about how to increase the CVP availability is true?

Question

Options

• AMust have SIP Proxy server to pass messages between the gateways and the CVP servers.
• BDeploy CVP with N+M redundancy.
• CDeploy CVP with N-1 redundancy.
• DDeploy CVP standalone to handle downtime.

• A
  4% (1)
• C
  88% (21)
• D
  8% (2)

Explanation

In a Cisco CVP centralized deployment, N-1 redundancy means you deploy enough CVP servers so that if any single server fails, the remaining N-1 servers can still carry the full call load - all servers are active and load-balanced, with no wasted standby capacity. This is Cisco's documented model for achieving CVP high availability within a single data center.

Why the distractors are wrong:

• A - A SIP Proxy assists with SIP message routing and scalability but is not a requirement for CVP availability; you can have high availability without one.
• B - N+M is not a standard Cisco CVP redundancy term; Cisco's model is N+1 (one hot standby) or N-1 (all-active with enough headroom), making N+M a fabricated distractor.
• D - Standalone deployment is the opposite of high availability - it creates a single point of failure, maximizing downtime risk rather than reducing it.

Memory tip: Think of N-1 as "Minus One, Still Done" - your CVP farm is sized so that dropping any one server still leaves enough active servers to finish every call.
