An administrator discusses a permanent site outage on an ECS system with the technology architect. What are the two expected behaviors from the ECS system under these circumstances? (Select 2)
The correct answer is A. A person must assess the circumstances to determine a permanent site outage. D. The VDC's objects and ownership are synchronized when network connectivity is restored. In Dell EMC ECS geo-federation, declaring an outage as permanent is a deliberate administrative action - ECS has no mechanism to automatically distinguish a temporary network disruption from a true permanent failure, so human judgment (option A) is always required…
Question
An administrator discusses a permanent site outage on an ECS system with the technology architect. What are the two expected behaviors from the ECS system under these circumstances? (Select 2)
Options
- AA person must assess the circumstances to determine a permanent site outage.
- BThe failed permanent site outage VDC can be added back to the cluster later.
- CNamespaces, buckets, and objects that are owned by the VDC are transferred to another VDC.
- DThe VDC's objects and ownership are synchronized when network connectivity is restored.

Explanation
In Dell EMC ECS geo-federation, declaring an outage as permanent is a deliberate administrative action - ECS has no mechanism to automatically distinguish a temporary network disruption from a true permanent failure, so human judgment (option A) is always required. Additionally, ECS's design is to synchronize the affected VDC's objects and ownership when network connectivity is restored (option D), meaning the system does not prematurely destroy or reassign data; it waits for the VDC to become reachable again before reconciling state.
Why B is wrong: A VDC declared as permanently failed is removed from the geo-federation cluster and cannot simply be re-added later - the permanent designation is terminal for that VDC's membership.
Why C is wrong: ECS does not automatically transfer namespaces, buckets, and object ownership to another VDC during a permanent outage. Data replicated to surviving VDCs remains accessible there, but ownership transfer is not an automatic behavior triggered by the outage declaration.
Memory tip: Think of it as "A.D. - Admin Decides" - the Administrator Decides it's permanent (A), and if the site somehow reconnects, Data synchronizes (D). The system never acts unilaterally on ownership (C is wrong) and never lets the failed VDC rejoin (B is wrong).
