When using IAM to control access to your RDS resources, the key names that can be used are case sensitive. For example, aws:CurrentTime is NOT equivalent to Aws:CurrentTime
Explanation: Key names are case-insensitive. For example, aws:CurrentTime is equivalent to AWS: currenttime
QUESTION: What will be the status of the snapshot until the snapshot is complete?
QUESTION: Can we attach an EBS volume to more than one EC2 instance at the same time?
- Only EC2-optimized EBS volumes
- Only in read mode
QUESTION: True or False:
Automated backups are enabled by default for a new DB Instance?

- A direct encrypted connection to Amazon S3
- It's a backup solution that provides an on-premises Cloud storage
- It provides an encrypted SSL endpoint for backups in the Cloud

- Just two: MySQL and Oracle
- Six: Amazon Aurora, Oracle, Microsoft SQL Server, PostgreSQL, MySQL and MariaDB
- Just one: MySQL
Answer: Three: MySQL, Oracle and Microsoft SQL Server
QUESTION: Fill in the blanks:
The base URI for all requests for instance metadata is __________________.
QUESTION: While creating the snapshots using the command line tools, which command should I be using?
QUESTION: Typically, you want your application to check whether a request generated an error before you spend any time processing results. The easiest way to find out if an error occurred is to look for a node in the response from the Amazon RDS API?
QUESTION: What are the two types of licensing options available for using Amazon RDS for Oracle?
- BYOL and Enterprise License
- BYOL and License Included
- Enterprise License and License Included

QUESTION: What does a "Domain" refer to in Amazon SWF?
- A security group in which only tasks inside can communicate with each other
- A special type of worker
- A collection of related Workflows
- The DNS record for the Amazon SWF service
Answer: A collection of related Workflows
Explanation: Domains provide a way of scoping Amazon SWF resources within your AWS account. All the components of a workflow, such as the workflow type and activity types, must be specified to be in a domain. It is possible to have more than one workflow in a domain; however, workflows in different domains cannot interact with each other.
QUESTION: EBS Snapshots occur
Explanation: Snapshots occur asynchronously; the point-in-time snapshot is created immediately, but the status of the snapshot is pending until the snapshot is complete (when all of the modified blocks have been transferred to Amazon S3), which can take several hours for large initial snapshots or subsequent snapshots where many blocks have changed.
QUESTION: Disabling automated backups ___________disable the point-in-time recovery.
- if configured to can
- will never
QUESTION: Out of the stripping options available for the EBS volumes, which one has the following disadvantage: 'Doubles the amount of I/O required from the instance to EBS compared to RAID 0, because you're mirroring all writes to a pair of volumes, limiting how much you can stripe.'?
- Raid 0
- RAID 1+0 (RAID 10)
- Raid 1
Answer: Raid 1
Explanation: raid 0 and 1 are the common types. Raid 5 and 6 are not recommended because of the extended stripe. If you encounter this question on the exam, I suspect the answer options will be different.
Raid 1 Disadvantage: Does not provide a write performance improvement; requires more Amazon EC2 to Amazon EBS bandwidth than non- RAID configurations because the data is written to multiple volumes simultaneously.
Raid 0 Disadvantage: Performance of the stripe is limited to the worst performing volume in the set. Loss of a single volume results in a complete data loss for the array.
Raid 5 and 6 notes: RAID 5 and RAID 6 are not recommended for Amazon EBS because the parity write operations of these RAID modes consume some of the IOPS available to your volumes. Depending on the configuration of your RAID array, these RAID modes provide 20-30% fewer usable IOPS than a RAID 0 configuration. Increased cost is a factor with these RAID modes as well; when using identical volume sizes and speeds, a 2-volume RAID 0 array can outperform a 4-volume RAID 6 array that costs twice as much.
QUESTION: Is creating a Read Replica of another Read Replica supported?
- Only in certain regions
- Only with MSSQL based RDS
- Only for Oracle RDS types
Answer: Only with MSSQL based RDS
QUESTION: Can I create a Read Replica of another Read Replica?
Amazon RDS for MySQL: You can create a second-tier Read Replica from an existing first-tier Read Replica. By creating a second-tier Read Replica, you may be able to move some of the replication load from the master database instance to a first-tier Read Replica. Please note that a second-tier Read Replica may lag further behind the master because of additional replication latency introduced as transactions are replicated from the master to the first-tier replica and then to the second-tier replica.
Amazon RDS for PostgreSQL: Read Replicas of Read Replicas are not currently supported.
QUESTION: Can Amazon S3 uploads resume on failure or do they need to restart?

QUESTION: What is the maximum write throughput I can provision for a single Dynamic DB table?
- 1,000 write capacity units

- Dynamic DB is designed to scale without limits, but if you go beyond 10,000 you have to contact AWS first
- 10,000 write capacity units
Answer: Dynamic DB is designed to scale without limits, but if you go beyond 10,000 you have to contact AWS first

- Removes one or more rules from a security group
- Removes a security group from our account

QUESTION: Can a 'user' be associated with multiple AWS accounts?
QUESTION: True or False:
Manually created DB Snapshots are deleted after the DB Instance is deleted?
Explanation: If you choose not to create a final DB snapshot, you will not be able to later restore the DB instance to its final state. When you delete a DB instance, all automated backups are deleted and cannot be recovered. Manual DB snapshots of the instance are not deleted.
QUESTION: What happens to the data on an instance if the instance reboots (intentionally or unintentionally)?
- Data will be lost
- Data persists
- Data may persist however cannot be sure
Answer: Data persists
Explanation: “Instance Store Lifetime” You can specify instance store volumes for an instance only when you launch it. The data in an instance store persists only during the lifetime of its associated instance. If an instance reboots (intentionally or unintentionally), data in the instance store persists. However, data in the instance store is lost under the following circumstances: The underlying disk drive fails the instance stops the instance terminates.
