You have recently joined a startup company building sensors to measure street noise and air quality in urban areas.
The company has been running a pilot deployment of around 100 sensors for 3 months Each sensor uploads 1KB of sensor data every minute to a backend hosted on AWS.
During the pilot, you measured a peak or 10 IOPS on the database, and you stored an average of 3GB of sensor data per month in the database
The current deployment consists of a load-balanced auto scaled Ingestion layer using EC2 instances and a PostgreSQL RDS database with 500GB standard storage.

Step -1 To transfer to S3 from global sites : Amazon S3 Transfer Acceleration enables fast, easy, and secure transfers of files over long distances between your client and your Amazon S3 bucket. S3 Transfer Acceleration leverages Amazon CloudFront's globally distributed AWS Edge Locations. Used to accelerate object uploads to S3 over long distances (latency). Transfer acceleration is as secure as a direct upload to S3.
Step -2 : When the application analyze/aggregate the data from S3 and then again upload the results - Multipart upload

NEW QUESTION 38
You have custom Network File System (NFS) client settings for your Amazon Elastic File System (EFS). It takes up to three seconds for an Amazon Elastic Compute Cloud (EC2) instance to see a write operation performed on a file system from another Amazon EC2 instance.
Which of the following actions should you take to solve the custom NFS settings from causing delays in the write operation?
- A. Verify that the IP address of the specified mount target is valid.
- B. Reduce the number of active users that have files open simultaneously on the instances.
- C. Unmount and remount the file system with the noac option to disable attribute caching.
- D. Run the write operation from a different user ID on the same Amazon EC2 instance.
Answer: C
Explanation:
When you set up custom NFS client settings, it takes up to three seconds for an Amazon EC2 instance to see a write operation being performed on a file system from another Amazon EC2 instance. To solve this issue, you must unmount and remount your file system with the noac option to disable attribute caching if the NFS client on the Amazon EC2 instance that is reading the data has attribute caching activated.
Attribute cache can also be cleared on demand by using a programming language that is compatible with the NFS procedures. To do this, you must send an ACCESS procedure request immediately before a read request.

"It probably ends up cheaper because you can take advantage of the CDN element, caching assets like images, css, js etc on CloudFront rather than having all traffic traverse the ALB to retrieve them. If you already use a CDN for these then you may not see any cost benefit adding it into the mix.
We also use CloudFront for SSL termination of 30+ customer sites, with a single ALB serving requests to the back end. We were using a separate CDN provider but we're moving all our assets into CloudFront too because it's going to end up way cheaper."
NEW QUESTION 41
A client of yours has a huge amount of data stored on Amazon S3, but is concerned about someone stealing it while it is in transit. You know that all data is encrypted in transit on AWS, but which of the following is wrong when describing server-side encryption on AWS?
- A. Amazon S3 server-side encryption uses one of the strongest block ciphers available, 256-bit Advanced
Encryption Standard (AES-256), to encrypt your data. - B. Server-side encryption is about data encryption at rest-that is, Amazon S3 encrypts your data as it writes it to disks.
- C. Amazon S3 server-side encryption employs strong multi-factor encryption.
- D. In server-side encryption, you manage encryption/decryption of your data, the encryption keys, and related tools.
Answer: D
Explanation:
Amazon S3 encrypts your object before saving it on disks in its data centers and decrypts it when you download the objects. You have two options depending on how you choose to manage the encryption keys: Server-side encryption and client-side encryption.
Server-side encryption is about data encryption at rest-that is, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it for you when you access it. As long as you authenticate your request and you have access permissions, there is no difference in the way you access encrypted or unencrypted objects. Amazon S3 manages encryption and decryption for you. For example, if you share your objects using a pre-signed URL, that URL works the same way for both encrypted and unencrypted objects.
In client-side encryption, you manage encryption/decryption of your data, the encryption keys, and related tools. Server-side encryption is an alternative to client-side encryption in which Amazon S3 manages the encryption of your data, freeing you from the tasks of managing encryption and encryption keys.
Amazon S3 server-side encryption employs strong multi-factor encryption. Amazon S3 encrypts each object with a unique key. As an additional safeguard, it encrypts the key itself with a master key that it regularly rotates. Amazon S3 server-side encryption uses one of the strongest block ciphers available,
2 56-bit Advanced Encryption Standard (AES-256), to encrypt your data.
