Exam Associate Cloud Engineer topic 1 question 184 discussion

Mission critical is the keyword here which specifies that we need to have a multi-regional backup of the data to survive any regional failures. So option D is the correct choice here.

Continuous access to data means Standard since all of the other options are for infrequently accessed storage (Nearline, Coldline, Archive). Since no other regions are mentioned, single region is best in this case

Here's why D is the optimal choice: Dual-regional storage: Provides high availability across two regions Ideal for mission-critical workloads Minimizes latency for Boston users by selecting nearby regions Provides geographic redundancy Standard storage class: Optimal for frequently accessed data ("used continually") No additional latency for access No additional retrieval costs Ideal for continuously running analytics pipelines

Mission-critcal

I will go for D

I need a spaceship, but please make it from the cheapest materials, my mission is very critical

I vote for B because of the keywords: miniaml-cost. The question even specified the single region that the use in, dual region wouldnt match the minimal cost requirement.

mission-critical = dual-regional

SLA with dual-region is higher than single region, which sounds normal : https://cloud.google.com/storage/sla So, as this platform is mission-critical, we have to maximize the SLA of the storage, so answer D.

Dual-Regional Storage: While dual-regional storage offers higher availability and redundancy by storing data in two geographic locations, it's typically more expensive than regional storage. For mission-critical applications where users are primarily in one geographic area (Boston), the added cost and complexity of dual-regional storage may not be necessary.

i think C

The correct answer is B. Configure regional storage for the region closest to the users. Configure a Standard storage class. The files are used in a mission-critical analytics pipeline that is used continually. This means that the files need to be available quickly and reliably. Regional storage is the best option for this because it ensures that the files are stored in the same region as the users. This will minimize latency and ensure that the files are available quickly. The Standard storage class is the best option for this because it provides a good balance between cost and performance. Nearline storage is a lower-cost option, but it is also slower. Standard storage is a good option for files that are used frequently, but not constantly. The other options are not as good for this scenario. Dual-regional storage is more expensive than regional storage, and it does not provide any performance benefits. Coldline storage is the lowest-cost option, but it is also the slowest.

I will go with B, as both dual-region and regional has 4 9's availability. https://cloud.google.com/storage/docs/locations

Correct answer is B Requirement is low cost and mission critical. It needs low latency which by using region storage will be achieved. Dual Storage is more expensive then multi regional. There is no need for dual storage in this case. If there will be a zonal failure it can be handled by regional storage. Using Dual storage here will increase cost.

B is correct answer. Cloud storage provides 11 9's durability which is safe for mission critical files. Plus the question provides the users location to be a single region, and minimal cost should be there.

Because Google Cloud Storage is 11 Nines durable (99.999999999%) its pretty safe for mission critical data (ref: https://cloud.google.com/blog/products/storage-data-transfer/understanding-cloud-storage-11-9s-durability-target). BUT the AVAILABILITY SLA on single region is 99.9% and for dual region its 99.95% (ONLY 0.05% better)... For the additional cost - dual region offers MINIMAL additional availability (ref: https://cloud.google.com/storage/docs/storage-classes#standard)
