Explore key concepts of buckets, disks, and data persistence in cloud storage environments. This quiz assesses your understanding of storage types, use cases, and the best practices for reliable data management in scalable cloud applications.
Which storage option is best suited for storing unstructured data like images, videos, and backups in a highly durable and scalable manner?
Explanation: Object buckets are designed for storing large amounts of unstructured data, such as media files and backup archives, providing scalability and high durability. Persistent disks are used primarily for block-level storage attached to compute instances for applications requiring frequent read/write operations. Local SSDs offer fast, temporary storage tied to a compute instance, which isn’t ideal for persistent or archival data. Block storage is a general term and lacks the inherent scalability and global accessibility of object storage solutions.
A company needs a storage solution that persists even if the virtual machine it is attached to is deleted or restarted. Which option best meets this requirement?
Explanation: Persistent disks maintain stored data independently of the lifecycle of a compute instance, ensuring that information remains intact even after deletion or restart. Local SSD and ephemeral disk are both temporary and data is lost when the instance is stopped or terminated. Temporal block is not a recognized cloud storage type, so it does not fit the scenario.
In a scenario where extremely low latency and high input/output operations per second are required for a running application, which storage type would provide the best performance?
Explanation: Local SSDs deliver the fastest performance for input/output operations and lowest latency, making them ideal for demanding workloads or databases requiring rapid access. Object buckets are not intended for high-frequency access as they have higher latency. Coldline buckets are designed for infrequent access, such as archival data. Standard persistent disks provide good performance but do not match the speed of local SSDs for intensive I/O tasks.
When managing large amounts of archival data that are accessed less than once a year, which storage class is most cost-effective?
Explanation: Coldline buckets are optimized for data accessed infrequently, such as annual backups or archives. They offer the lowest storage costs compared to other classes but charge higher fees for retrievals, making them ideal for rarely accessed data. Standard buckets are priced for frequent access. Nearline buckets are suitable for data accessed about once a month. Premium disk is a misleading option, as it's not suited for long-term, low-access archival storage.
Which storage solution allows users to store files in the cloud and retrieve them from any location via a URL, supporting global access and distribution?
Explanation: Object buckets support storing files accessible via URLs, enabling global distribution and easy retrieval from any location. Block storage volumes and persistent disks are attached to specific compute instances and are not directly accessible over the internet. Linear tape storage is an on-premises archival solution and does not provide cloud-based, globally accessible files via internet URLs.
