A global e-commerce company uses Dell ECS to store product catalogs. They have a primary site that must replicate data to three regional sites for disaster recovery. Each regional site needs a full copy of the data, and the network links have varying bandwidth. Which replication topology should the architect implement?

Many-to-one replication from the regional sites to the primary site

Cascaded replication from the primary to one regional site, then to the others

Active-active replication between all four sites

One-to-many replication from the primary site to all three regional sites

Which trade-off is typically associated with replication compared to erasure coding?

Higher performance but lower durability

Higher storage overhead but simpler data reconstruction

Lower storage overhead but more complex reconstruction
