3.Alibaba Cloud Network Attached Storage(NAS)is a highly reliable,highly available file storage service featuring a distributed file system with unlimited capacity and performance scaling,with namespace and multiple client access support. NAS support standard file access protocols，so existing applications do not need to be modifiedWhich of the following options are the scenarios that ECS can benefit from by using NAS（3 answers）选项： A:Deploying services using Server Load Balancer and multiple ECS servers same bucket to share data B:Sharing logs for when apps on multiple ECS servers need to write logs to the same bucket to facilitate concentrated log data processing and analysis C:Sharing files where NAS enables you to store your enterprises public files in a centralized manner and share data to multiple business groups, all while maintaining data security D:Making a data pool that all the files can be put in a structured way which can be easily integrated as Maxcompute data source E:Making applications running on the same file system can communicate with each other easier and faster by always reading and writing to the same fie

4. A disaster response team is using drones to collect images of recent storm damage. The response team’s laptops lack the storage and compute capacity to transfer the images and process the data. While the team has Amazon EC2 instances for processing and Amazon S3 buckets for storage, network connectivity is intermittent and unreliable. The images need to be processed to evaluate the damage.What should a solutions architect recommend？选项： A: Use AWS Snowball Edge devices to process and store the images B: Upload the images to Amazon Simple Queue Service（Amazon SQS）during intermittent connectivity to EC2 instances. C: Configure Amazon Kinesis Data Firehose to create multiple delivery streams aimed separately at the S3 buckets for storage and the EC2 instances for processing the images D: Use AWS Storage Gateway pre-Installed on a hardware appliance to cache the images locally for Amazon S3 to process the images when connectivity becomes available
