Which of the following are the characteristics of Block Storage?(Select Three)
- A. Highly available and resilient and will often include data encryption at rest and in transit
- B. Block storage is suitable for workloads where there needs to be some level of disk sharing between compute nodes
- C. Block Storage normally mounted onto only one compute node at a time
- D. Block storage is suitable for applications where disk speed is important
正解：A、C、D
解説：
Block storage is economical than the other types of storage
Explanation:
Block storage is used to store data files on Storage Area Networks (SANs) or cloud-based storage environments. It can be attached to compute instance. Block Storage normally mounted onto only one compute node at a time. With block storage, you specify the size of the storage and pay a fee based on the size you provisioned. Use Cases: Block storage suitable for low latency workloads where consistently high speeds required. Features: -Offer volume size from 20 GB to 12 TB, -Provide encryption for data at rest -Provide IOPS upto 48,000 IOPS -Highly available and resilient.
質問 # 106
What tier of Object Storage class should be used where data is accessed only a few times per year?
- A. Standard
- B. Vault
- C. Hot Tier
- D. Cold vault
正解：D
解説：
Cold Vault (for cold data): Use this option for data accessed only a few times a year. A larger retrieval charge applies for reading data. Common use cases include long-term backup, large data set preservation, or older media content. Cold Vault includes a threshold for object size and storage period with a minimum billable object size of 256 KB and a minimum storage duration of 90 days. Objects smaller than the minimum size will incur a charge for the minimum billable object size. In-Correct Answers : Standard (for active data) : Use this level for active data that's accessed multiple times a month. Your data is immediately available when needed. Common use cases include streaming mobile and web content, DevOps, analytics, collaboration and active content repositories. There are no retrieval charges, no minimum object size and no minimum duration requirement. Vault (for less active data): Use this level for less active data that's accessed once a month or less. Data is immediately available when needed. A low retrieval charge applies for reading data. Common use cases include backup and digital asset retention. Vault includes a threshold for object size and storage period with a minimum billable object size of 128 KB and a minimum storage duration of 30 days. Hot Tier : Hot tier is built in tier type of Smart tier.With Smart Tier, you no longer have to worry about selecting the right storage class for your workloads. Smart Tier will track your monthly activity and bill you one monthly capacity rate from three built-in pricing tiers: hot, cool, or cold. Smart Tier: Smart Tier employs automatic cost optimization to ensure that you get the lowest storage cost each month. This is valuable for all workloads, especially ones with variable or unpredictable data access patterns and ones that change over time.

- B. Region
- C. Zone
- D. Datacenter
- E. Resource Group
正解：A
解説：
Resource : A resource is an instance of a service like Cloudant, a Cloud Foundry application, Virtual Machine, Container. Resources are provisioned globally in an account scope. Resource Group : Resource group is a collection of resources like Virtual Machine, each resource group belongs to an account. all resources are created within a resource group. if a resource group is deleted then all the resources of that particular resource group also deleted. Region : Regions is a physical location with multiple availability zones, Regions are completely independent of each other, They're connected through a dedicated regional low-latency network. each region is located in separate geographic area. Zones : Zones are physically separate locations within each region, that are engineered to be isolated from failures. if we deploy application across two Availability Zones than It increases the availability of an application compared to running in a single Availability Zone. Datacenter : Within an availability zone, We can have multiple data centers. It can simply be a building where infrastructure is managed for a cloud.

Horizontal pod autoscaler enables customers to determine the minimum or the maximum number of pods to run the CPU and memory utilization the pods should utilize. The HPA automatically scales the workload to match the demand. When there is an increased workload, it deploys more pods. When there is a decrease in the workload, it communicates to the workload resource to scale back down.

What is a key feature of Virtual Private Cloud?
- A. Applications are automatically deployed across 3 zones
- B. To run an isolated environment within a public cloud
- C. Network traffic between VSIs on the private network
- D. It is deploy on-premises for increased security
正解：B
解説：
Virtual Private Cloud used to run an isolated environment within a public cloud. A VPC is a public cloud offering that lets an enterprise establish its own private cloud-like computing environment on shared public cloud infrastructure. A VPC gives an enterprise the ability to define and control a virtual network that is logically isolated from all other public cloud tenants, creating a private, secure place on the public cloud. - VPC provides security in two ways. At the instance level protection is provided through security groups. At the subnet level, protection is provided by access control lists. Site-to-site virtual private networks (VPN) can be configured. A public gateway is used to enable egress to the internet for all virtual server instances on the attached subnet. - VPC provides flexibility when customers securely connect to on premises or remote infrastructure. VPCs can be created in various regions around the world. Customers can select a private IP address or bring their own IP address for cloud applications. Using Direct Link helps create a dedicated connection between the cloud and on premises resources. This allows an organization to extend its network and provide a consistent connection without using the public internet. - Responsiveness VPC makes it possible to create responsive cloud applications. Instance profiles with elasticity are used when creating applications for workloads, horizontal scaling, performance monitoring, and load balancing services.
