Discuss Nokia 4A0-F10 Exam Topic 1 Question 4

Why must a managed ONT or residential gateway be reachable before an Auto Configuration Server can provision it using TR-069?

ATR-069 requires an active management session with the device.

BTR-069 writes configuration directly to a passive splitter.

CTR-069 can configure only devices that are physically inside the central office.

DTR-069 communicates exclusively through an OLT serial console.

Suggested Answer: A

TR-069 enables remote management through communication between customer-premises equipment and an Auto Configuration Server. The device must be powered, operational, and able to establish or participate in a management session before configuration parameters, software information, diagnostics, or status data can be exchanged. An ACS cannot provision a device that is completely offline because no active communication path exists. TR-069 does not configure passive splitters, which contain no management processor or configurable service logic. The managed device can be located at the subscriber premises and does not need to be inside the central office. Communication is carried over the device's network connection rather than exclusively through an OLT serial console. Authentication and protected transport help secure management exchanges between the device and the ACS.

B doesn't make sense. A passive splitter can't be managed directly.

Goldie 2 months ago

Agreed! Without an active session, no configuration can happen.

Aileen 2 months ago

I think A is the right answer. The device needs to be reachable for management.

Latia 2 months ago

C is just plain false, devices can be anywhere!

B is definitely wrong, it doesn't write to splitters.

Tandra 2 months ago

Wait, can it really only work if it's online? Sounds fishy.

Totally agree, it needs to be reachable first!

A) TR-069 requires an active management session with the device.

I thought TR-069 could work with devices not in the central office, so C seems off to me.

Lelia 3 months ago

I feel like I've seen a question like this before, and it was definitely about the device being online for configuration.

I'm not entirely sure, but I remember something about TR-069 needing the device to be reachable for provisioning.

Hubert 3 months ago

I think the answer might be A because TR-069 needs an active session to manage the device, right?
