Exam Associate Cloud Engineer topic 1 question 6 discussion

Best Answer is " Archive Storage " https://cloud.google.com/storage/docs/storage-classes But as per the given option next best solution is " Coldline Storage"

D is correct, Coldline Storage COLDLINE 90 days 99.95% in multi-regions and dual-regions 99.9% in regions

Answer is D.

Ans is D. Coldline Storage: If the backups are truly for disaster scenarios and you expect very infrequent access (less than once a year). Here's how other option fits into this context: A. Multi-Regional Storage: This is best for data that is frequently accessed and needs to be highly available. It's ideal for serving content to users globally and for data that is accessed more often. B. Regional Storage: This offers high availability and is suited for storing data that is accessed frequently, but within a specific region. It's good for data used in compute operations in the same region. C. Nearline Storage: This is a low-cost option for storing infrequently accessed data. It's ideal for data that is accessed less than once a month. There are costs associated with accessing the data, so it's better for data that you don't expect to access frequently.

honestly, they should've added archive storage because it is better suited for disaster recovery backup. It is also stated in the doc how archive is better choice than 'coldline storage'. Also in terms of latency, archive will take care of that in events of disaster; as stated in the doc, "In the event of a disaster recovery event, recovery time is key. Cloud Storage provides low latency access to data stored as Archive storage." https://cloud.google.com/storage/docs/storage-classes#archive

Correct Answer: D Reference: https://cloud.google.com/storage/docs/storage-classes#nearline

Multi-regional storage = standard storage used only for objects stored in multi-regiones or dual-regions. Regional storage = standard storage used only for objects stored in regions Refer to https://cloud.google.com/storage/docs/storage-classes#legacy Each of the standard, nearline, coldline, and archive storage classes can have any of the location types, i.e., region, dual region, multi-region. Cold-line storage is the ideal option here according to Google's best practices.

Google recommends Archive Storage for disaster recovery, since Archive is not available as an answer, coldline is the nearest possible.

disaster recovery purposes = Multi-Regional Storage https://cloud.google.com/storage/docs/locations#location_recommendations

https://cloud.google.com/docs/geography-and-regions

This talks about disaster recovery and you need to be able to retrieve data according to the RTO, except for Nearline all others only guarantee 99.95 availability and you want to avoid retrieval costs. All the other storage classes have a cost associated with it. With that in mind nearline is the best storage class from a DR perspective.

Best answer is D. Coldline Storage. The choices specifically said Multi-Regional and Regional "Storage". Multi-Regional Storage is equivalent to Standard Storage and is different to Multi-regional location. Check additional classes: https://cloud.google.com/storage/docs/storage-classes#legacy

for disaster recovery multi region is recommended.

Answer should be ARCHIVE STORAGE Archive storage Archive storage is the lowest-cost, highly durable storage service for data archiving, online backup, and disaster recovery. Unlike the "coldest" storage services offered by other Cloud providers, your data is available within milliseconds, not hours or days. https://cloud.google.com/storage/docs/storage-classes#:~:text=Archive%20storage%20is%20the%20lowest,milliseconds%2C%20not%20hours%20or%20days.

The correct answer is D

B is correct following Google best practices

D is correct
