Q2. Your company has been storing a lot of data in Amazon Glacier and has asked for an inventory of what is in there exactly. So you have decided that you need to download a vault inventory. Which of the following statements is incorrect in relation to Vault Operations in Amazon Glacier?
A. You can use Amazon Simple Notification Service (Amazon SNS) notifications to notify you when the job completes.
B. A vault inventory refers to the list of archives in a vault.
C. You can use Amazon Simple Queue Service (Amazon SQS) notifications to notify you when the job completes.
D. Downloading a vault inventory is an asynchronous operation.
Answer: C
Explanation:
Amazon Glacier supports various vault operations.
A vault inventory refers to the list of archives in a vault. For each archive in the list, the inventory provides archive information such as archive ID, creation date, and size. Amazon Glacier updates the vault inventory approximately once a day, starting on the day the first archive is uploaded to the vault. A vault inventory must exist for you to be able to download it.
Downloading a vault inventory is an asynchronous operation. You must first initiate a job to download the inventory. After receMng the job request, Amazon Glacier prepares your inventory for download. After the job completes, you can download the inventory data.
Given the asynchronous nature of the job, you can use Amazon Simple Notification Service (Amazon SNS) notifications to notify you when the job completes. You can specify an Amazon SNS topic for each indMdual job request or configure your vault to send a notification when specific vault events occur. Amazon Glacier prepares an inventory for each vault periodically, every 24 hours. If there have been no archive additions or deletions to the vault since the last inventory, the inventory date is not updated. When you initiate a job for a vault inventory, Amazon Glacier returns the last inventory it generated, which is a point-in-time snapshot and not real-time data. You might not find it useful to retrieve vault inventory for each archive upload. However, suppose you maintain a database on the client-side associating metadata about the archives you upload to Amazon Glacier. Then, you might find the vault inventory useful to reconcile information in your database with the actual vault inventory.

Q6. Your customer wishes to deploy an enterprise application to AWS which will consist of several web servers, several application servers and a small (50GB) Oracle database information is stored, both in the database and the file systems of the various servers. The backup system must support database recovery whole server and whole disk restores, and indMdual file restores with a recovery time of no more than two hours. They have chosen to use RDS Oracle as the database
Which backup architecture will meet these requirements?
A. Backup RDS using automated daily DB backups Backup the EC2 instances using AMs and
supplement with file-level backup to 53 using traditional enterprise backup software to provide fi Ie level restore
B. Backup RDS using a Multi-AZ Deployment Backup the EC2 instances using Amis, and supplement by copying file system data to 53 to provide file level restore.
C. Backup RDS using automated daily DB backups Backup the EC2 instances using EBS snapshots and supplement with file-level backups to Amazon Glacier using traditional enterprise backup software to provide file level restore
D. Backup RDS database to 53 using Oracle RMAN Backup the EC2 instances using Amis, and supplement with EBS snapshots for indMdual volume restore.
Answer: A
Explanation:
Point-In-Time Recovery
In addition to the daily automated backup, Amazon RDS archives database change logs. This enables you to recover your database to any point in time during the backup retention period, up to the last five minutes of database usage.
Amazon RDS stores multiple copies of your data, but for Single-AZ DB instances these copies are stored in a single availability zone. If for any reason a Single-AZ DB instance becomes unusable, you can use point-in-time recovery to launch a new DB instance with the latest restorable data. For more information on working with point-in-time recovery, go to Restoring a DB Instance to a Specified Time.
Note
Mu|ti-AZ deployments store copies of your data in different Availability Zones for greater levels of data durability. For more information on Multi-AZ deployments, see High Availability (MuIti-AZ).

Q9. A user is storing a large number of objects on AWS S3. The user wants to implement the search functionality among the objects. How can the user achieve this?
A. Use the indexing feature of S3.
B. Tag the objects with the metadata to search on that.
C. Use the query functionality of S3.
D. Make your own DB system which stores the S3 metadata for the search functionality.
Answer: D
Explanation:
In Amazon Web Services, AWS S3 does not provide any query facility. To retrieve a specific object the user needs to know the exact bucket / object key. In this case it is recommended to have an own DB system which manages the S3 metadata and key mapping.

Q13. A user has created photo editing software and hosted it on EC2. The software accepts requests from the user about the photo format and resolution and sends a message to S3 to enhance the picture accordingly. Which of the below mentioned AWS services will help make a scalable software with the AWS infrastructure in this scenario?
A. AWS Simple Notification Service
B. AWS Simple Queue Service
C. AWS Elastic Transcoder
D. AWS Glacier
Answer: B
Explanation:
Amazon Simple Queue Service (SQS) is a fast, reliable, scalable, and fully managed message queuing service. SQS provides a simple and cost-effective way to decouple the components of an application. The user can configure SQS, which will decouple the call between the EC2 application and S3. Thus, the application does not keep waiting for S3 to provide the data.

Q15. You are using Amazon SES as an email solution but are unsure of what its limitations are. Which statement below is correct in regards to that?
A. New Amazon SES users who have received production access can send up to 1,000 emails per 24-hour period, at a maximum rate of 10 emails per second.
B. Every Amazon SES sender has a the same set of sending limits
C. Sending limits are based on messages rather than on recipients
D. Every Amazon SES sender has a unique set of sending limits
Answer: D
Explanation:
Amazon Simple Email Service (Amazon SES) is a highly scalable and cost-effective email-sending
service for businesses and developers. Amazon SES eliminates the complexity and expense of building an in-house email solution or licensing, installing, and operating a third-party email service for this type of email communication.
Every Amazon SES sender has a unique set of sending limits, which are calculated by Amazon SES on an ongoing basis:
Sending quota — the maximum number of emails you can send in a 24-hour period. Maximum send rate — the maximum number of emails you can send per second.
New Amazon SES users who have received production access can send up to 10,000 emails per 24-hour period, at a maximum rate of 5 emails per second. Amazon SES automatically adjusts these limits upward, as long as you send high-quality email. If your existing quota is not adequate for your needs and the system has not automatically increased your quota, you can submit an SES Sending Quota Increase case at any time.
Sending limits are based on recipients ratherthan on messages. You can check your sending limits at any time by using the Amazon SES console.
Note that if your email is detected to be of poor or QUESTION able quality (e.g., high complaint rates, high bounce rates, spam, or abusive content), Amazon SES might temporarily or permanently reduce your permitted send volume, or take other action as AWS deems appropriate.
