Questioned state should come with a little bit of extra information. Check for this under DFM > Device Management > Rediscover/Delete. Typically, a device will be questioned if there is a problem either pinging the device, or querying it via SNMP. Other causes of devices in the questioned state are responses that are sourced from a different IP address from the one queried, or delays in responses.
You should see some errors in the NMSROOT/objects/smarts/local/logs/DFM.log that may give you more of a clue.
Absolutely. DFM uses ping (icmp) to verify reachability. Ideally, you will want to enable ICMP to all IP addresses on all devices, but there is a way to get around this by calling the TAC and referencing bug CSCsb48643.
But to be absolutely clear, ICMP must be permitted to the management IP address of the device.
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
