The question specifies "users in the West US region can READ data". Geo redundancy should cut it and Multi region writes are unnecessary.

There is no need for multi-region writes only geo-redundancy. See https://docs.microsoft.com/en-us/azure/azure-sql/database/active-geo-replication-overview You can create the secondary across the country where it would have low latency for someone nearby and it would be readable.

The question is asking the Azure Cosmos DB, not Azure SQL Database in your link.

I am also now wondering why they suggested using the availability zones feature. The way the question is worded, "ensure that users in the West region can read..." makes me wonder if "ensure" is the key word here and that's why they are also enabling the availability zones which I would not have done if I was only interested in saving money.

It make sense to enable the "Availability Zones" as part of the requirement since there is a chance the replicated server could go down.

You're right. Sorry about that. In this link (https://docs.microsoft.com/en-us/azure/cosmos-db/high-availability) look at the section on multi-region accounts with a single write region. There is no need given the stated objectives to enable multi-region writes. Thanks for the catch.
