Question 1: A Communication Manager duplex pair is operating normally. What is the expected server role relationship?
Choices:
1) Both servers process calls actively at the same time 2) One server is active and the other is standby 3) Both servers remain standby until Session Manager requests service 4) One server handles signaling while the other handles media
Correct Answer: One server is active and the other is standby
Explanation: Communication Manager duplex high availability uses an active/standby server pair. The standby maintains synchronized state so it can assume the active role during a server interchange.Page 1
Question 2: What event best describes a Communication Manager server
interchange in a duplex con�guration?
Choices:
1) The active server changes its SIP domain 2) Session Manager moves all SIP users to System Manager 3) The media gateway changes its �rmware source 4) The standby server assumes the active role
Correct Answer: The standby server assumes the active role
Explanation: A server interchange occurs when the standby Communication Manager becomes active, typically because the active server is less healthy or unavailable.
Question 3: Why must the duplication link between Communication Manager duplex
servers be highly reliable?
Choices:
1) It keeps the standby server synchronized with the active server 2) It carries endpoint RTP media for every call 3) It distributes �rmware to all SIP phones 4) It replaces DNS resolution for the Aura core
Correct Answer: It keeps the standby server synchronized with the active server
Explanation: The duplication link is used to maintain synchronization between the active and standby Communication Manager instances so the standby can take over with minimal service impact.Page 2
Question 4: An engineer is designing a Communication Manager duplex deployment.
Which network characteristic is most important for the duplication connection?
Choices:
1) Public Internet reachability 2) A di�erent IP subnet for each duplication interface 3) Low packet loss and predictable latency 4) NAT between the two duplication interfaces
Correct Answer: Low packet loss and predictable latency
Explanation: Duplex synchronization depends on a stable, low-loss, low-latency path. Unreliable transport can impair synchronization and high-availability behavior.
Question 5: Which statement best distinguishes Communication Manager duplex
redundancy from an Enterprise Survivable Server design?
Choices:
1) Duplex redundancy is used only for SIP endpoints, while a survivable server is used only for H.323 endpoints 2) Duplex redundancy provides an active/standby core pair, while a survivable server provides alternate call control when the main core is unreachable 3) Duplex redundancy requires System Manager to process calls, while a survivable server does not 4) Duplex redundancy replaces Session Manager, while a survivable server replaces System Manager Correct Answer: Duplex redundancy provides an active/standby core pair, while a survivable server provides alternate call control when the main core is unreachable Explanation: A duplex pair protects the primary Communication Manager service with active/ standby redundancy. A survivable server is a separate call-control resource intended to maintain service when the main core cannot be reached.Page 3
