What is a protection policy in ECS?

A set of rules that define replication and erasure coding settings

An organization is designing a three-site ECS federation for geo-redundancy. They want to ensure that if one site becomes completely unavailable, the remaining two sites can still serve reads and writes without manual intervention. Which federation topology meets this requirement?

A single active site with two passive sites that only receive replicas

Two active sites and one passive site

One active site and two sites that are active only for reads

Three active sites with synchronous replication between all pairs

A global e-commerce company uses a multi-site ECS federation. They need to ensure that a write to one site is visible to reads at another site within a few seconds, but they can tolerate occasional brief inconsistencies during network partitions. Which consistency model and replication type should they choose?

Eventual consistency with synchronous replication

Strong consistency with synchronous replication

Strong consistency with asynchronous replication

Eventual consistency with asynchronous replication

A logistics company uses a two-site ECS federation. They need to ensure that a shipment tracking update is not lost even if the primary site fails immediately after the write is acknowledged. They are considering synchronous replication. What is the primary trade-off they must accept?

Lower availability because the primary site cannot accept writes during a network partition

Increased write latency due to waiting for the remote site acknowledgment

Increased read latency because reads must be served from the remote site

Reduced storage capacity because synchronous replication requires more copies

A government agency runs a single-site ECS cluster and must protect against the failure of an entire rack. The cluster spans three racks, and the administrator wants to configure a protection policy that ensures data survives a full rack loss. Which approach should be used?

Erasure coding with chunks distributed across all three racks

Replication factor of 3 with all copies on the same node

Replication factor of 2 with copies placed on different nodes within the same rack

Erasure coding with all chunks stored on a single rack
