An orders table is keyed by order_id. A new access pattern needs recent orders for one customer and should return status and total directly from the index. Which design choices meet the requirement? Select 2 answers.

1. Use customer_id as the GSI partition key and an ordered order timestamp, with a tie-breaker if needed, as its sort key.
2. Use one constant customer partition key and filter out every other customer after the query.
3. Project status and total into the GSI using an appropriate projection and account for its eventual consistency.
4. Request strongly consistent reads from the GSI to guarantee immediate visibility after every write.
5. Leave status and total unprojected and assume the GSI query always returns all base-table attributes.
