A) Set the memcache service level to dedicated. Create a key from the hash of the query, and return database values from memcache before issuing a query to Cloud SQL.
B) Set the memcache service level to dedicated. Create a cron task that runs every minute to populate the cache with keys containing query results.
C) Set the memcache service level to shared. Create a cron task that runs every minute to save all expected queries to a key called ''cached-queries''.
D) Set the memcache service level to shared. Create a key called ''cached-queries'', and return database values from the key before using a query to Cloud SQL.

Wait, can we really trust memcache for critical data? Sounds sketchy!

D is a good approach, but shared memcache might have issues with collisions.

C seems a bit risky, what if the queries change often?

I think B is better, cron jobs can keep the cache fresh.

I recall that using a shared memcache might be less efficient, but I can't quite remember the details on when to use dedicated versus shared.

I’m a bit confused about the cron task in option B. I feel like it could lead to stale data if it runs too frequently.

I think option A sounds familiar because it mentions creating a key from the hash of the query, which we practiced in class.

I remember we discussed using memcache to reduce database queries, but I'm not sure if dedicated or shared is better for this scenario.

This seems pretty straightforward. I'll focus on the key requirements like threats and vulnerabilities.

Okay, I think I've got a good handle on this. The key is to focus on the specific details provided in the question. Options A and B seem like they could be true, but I'm not sure about C and D. I'll mark A and B and leave the others unchecked.

Hmm, I'm not entirely sure about this one. I know the Office Deployment Tool has some information on releases, but I'm not confident that's the best choice here. I'll have to think this through a bit more.
