Cloud Storage Flashcards
What are the three popular storage solutions in computing environments?
Block, File, and Object storage
Which storage solution operates at the operating system kernel level, stores and organizes data as an array of unrelated blocks?
Block Storage
Which storage solution operates at the operating system user level, stores data as data blocks which are managed by a file system?
File storage
Which storage solution operates at the application level, stores the data as objects?
Object storage
Which Amazon service is an online cloud-based data storage infrastructure for storing and retrieving any amount of data?
Amazon Simple Storage Service (S3)
Which Amazon service provides a highly scalable, available, and durable file storage which can be used with EC2 instances?
Amazon Elastic File System (EFS)
Which Amazon service provides block level storage volumes for use with EC2 instances?
Amazon Elastic Block Store (EBS)
Which Amazon service connects an on-premises software appliance with cloud-based storage to provide seamless and secure integration between an organization’s on-premises IT environment and AWS’s storage infrastructure?
AWS Storage Gateway
What service is used for providing cloud storage solutions for on-premises servers?
AWS Storage Gateway
You can use _________________ to automate the creation, retention, and deletion of snapshots taken to back up your Amazon EBS Volumes.
Amazon Data Lifecycle Manager (Amazon DLM)
What service is used for creating backup of data from your on-premises server and not from the Amazon Virtual Private cloud?
Amazon Storage Gateway
What service offers a simple encryption solution for your EBS volumes without the need to build, maintain, and secure your own key management infrastructure?
EBS encryption
In Amazon S3 how do you protect data in transit?
By using SSL or by using client-side encryption.
In Amazon S3, what are your options for protecting data at rest?
- Server-Side Encryption - You request Amazon S3 to encrypt your object before saving it on disks in its data centers and decrypt it when you download the objects.
- Client-Side Encryption - You can encrypt data client-side and upload the encrypted data to Amazon S3. In this case, you manage the encryption process, the encryption keys, and related tools.
What are the 3 volume types provided by Amazon EBS?
General Purpose (SSD)
Provisioned IOPS (SSD)
Magnetic
Which EBS volume types provided is suitable for a broad range of workloads, including small to medium-sized databases, development and test environments, and boot volumes? This volume types is recommended as the default choice for customers?
General Purpose (SSD)
Which EBS volume types provided offer storage with consistent and low-latency performance and are designed for I/O intensive applications such as large relational or NoSQL databases?
Provisioned IOPS (SSD)
Which volume type provides the lowest cost per gigabyte of all EBS volume types?
Magnetic
Which EBS volume types are ideal for workloads where data are accessed infrequently, and applications where the lowest storage cost is important?
Magnetic Volumes
Which EBS volume type allows you to use the multi-attach feature?
Provisioned IOPS io2 or io1 volumes.
The EBS multi attach feature only allows an EBS volume to be attached on multiple instances within ____________
1 Availability Zone
____________ is an easy-to-use, high-performance block storage service designed for use with Amazon Elastic Compute Cloud (EC2) for both throughput and transaction-intensive workloads at any scale.
Amazon Elastic Block Store (EBS)
__________________ is an object storage service that offers industry-leading scalability, data availability, security, and performance.
Amazon Simple Storage Service (S3)
In an __________________, you can define rules to transition objects from one storage class to another to save on storage costs.
S3 Lifecycle configuration.
A ____________ is simply a temporary block-level storage for EC2 instances.
Instance Store Volume
You can specify the instance store volumes for your instance only when?
You launch it.
Encryption by default is a _______________ setting. If you enable it for a ______________, you can not disable it for individual volumes or snapshots in that __________.
Region
Does Amazon EBS support asymmetric KMS keys?
No, to encrypt an EBS snapshot, you need to use symmetric encryption KMS keys.
A company is using an On-Demand EC2 instance to host a legacy web application that uses an Amazon Instance Store-Backed AMI. The web application should be decommissioned as soon as possible and hence, you need to terminate the EC2 instance. When the instance is terminated, what happens to the data on the root volume?
Data is automatically deleted.
EBS volumes support _________________ while in production which means that you can modify the volume type, volume size, and IOPS capacity without service interruptions.
Live configuration changes
When you create an EBS volume in an Availability Zone, it is ______________ within that zone to prevent data loss due to a failure of any single hardware component.
Automatically replicated
After you create an EBS volume, you can attach it to any instance where?
In the same availability zone
EBS encryption enables data at rest security by encrypting your data using _______________, or ________________.
Amazon-managed keys or keys you create using the AWS Key Management Service (KMS)
___________________ provides simple, scalable, elastic file storage for use with AWS Cloud services and on-premises resources.
Amazon Elastic File System (EFS)
When mounted on Amazon EC2 instances, an ________________ provides a standard file system interface and file system access semantics, allowing you to seamlessly integrate this service with your existing applications and tools.
Amazon Elastic File System
_____________ is an in-memory data store that improves the performance of your applications.
Amazon ElastiCache
When you see the phrase “allow concurrent connections from multiple EC2 instances” which AWS storage option should you think of?
Amazon Elastic File Storage
Which AWS storage solution is more suitable for scenarios where it is required to have a POSIX-compatible file system or if you are storing rapidly changing data?
Amazon EFS
Which storage solution makes data available through an Internet API that can be accessed anywhere?
Amazon S3
Which storage solution can deliver performance for workloads that require the lowest-latency access to data from a single EC2 instance?
Amazon EBS
You can use ______________ with Amazon ECS to access file system data across your fleet of Amazon ECS tasks. That way, your tasks have access to the same persistent storage, no matter the infrastructure or container instance on which they land.
Amazon EFS file systems
With _____________ mode, a file system’s throughput scales as the amount of data stored in the EFS standard or One Zone storage class grows.
Bursting Throughput mode
__________________ mode for Amazon EFS is available for applications with high throughput to storage (MiB/s per TiB) ratios.
Provisioned Throughput Mode
