HOTSPOT
You manage an Azure subscription.
You develop a storage plan with the following requirements:
Database backup files that are generated once per year are retained for ten years. ✑
High performance system telemetry logs are created constantly and processed for analysis
every month.
In the table below, identify the storage redundancy type that must be used. Make only one
selection in each column.

I agree. I have found something similiar here http://ms70533.free-exams.com..
What’s the explanation for this? Why is GRS the option to retain the backup for 10 yrs? Why is it LRS for telemetry?
I think LRS for the telemetry data because it is implying that the data is written constantly. LRS is cheaper per transaction than the other options. See https://azure.microsoft.com/en-gb/pricing/details/storage/. As for the db backups…I’m not sure why GRS, because let’s face it, if you’re only storing a db backup once per year for 10 years it’s not to do restores from, unless you want a vERY out of data database, it’s for auditting reasons. So why GRS? Anyone?
There is this from https://msdn.microsoft.com/en-us/library/jj919148.aspx. But it’s implying the db backups should be stored on geo replicated storage for DR purposes so you can restore them. In the question though 1 backup per year for 10 years is unlikely to be for restoring from.
“Benefits of Using the Microsoft Azure Blob Service for SQL Server Backups
Flexible, reliable, and limitless off-site storage: Storing your backups on Microsoft Azure Blob service can be a convenient, flexible, and easy to access off-site option. Creating off-site storage for your SQL Server backups can be as easy as modifying your existing scripts/jobs. Off-site storage should typically be far enough from the production database location to prevent a single disaster that might impact both the off-site and production database locations. By choosing to geo replicate the Blob storage you have an extra layer of protection in the event of a disaster that could affect the whole region. In addition, backups are available from anywhere and at any time and can easily be accessed for restores.”
