Question ID 12872

Which two statements about the Peer Firmware Sharing option for IP phone firmware
distribution are true? (Choose two.)

Option A

This option uses a parent-child hierarchy in which a firmware image is downloaded by a parent phone to up to three directly associated child phones.

Option B

This option must be enabled on Cisco Unified Communications Manager service parameters for Cisco TFTP.

Option C

This option mandates that the parent phone and child phones be identical, selected phone models.

Option D

This option allows firmware transfers between phones in different subnets, as long as the round-trip delay is less than 5 milliseconds.

Option E

This option uses a parent-child hierarchy that must be manually defined by the Cisco Unified Communications Manager administrator.

Option F

This option allows falling back to the TFTP server in the Cisco Unified Communications Manager cluster.

Correct Answer C,F
Explanation Explanation: Peer Firmware Sharing works by setting up a parent-child hierarchy of the phones in which a firmware image is downloaded by the parent phone to a child phone. The advantage of using Peer Firmware Sharing is that instead of all phones individually retrieving a software image, they pass the image along from one phone to another phone on the same subnet. Advantage of PFS: ✑ Hierarchy is automatic ✑ One download per phone model on a subnet ✑ Uses TCP ✑ Fails back to TFTP ✑ Speeds up LAN upgrades ✑ Reduces TFTP CPU load during upgrade
