NEW QUESTION 4
A company is building a two-tier web application to serve dynamic transaction-based content. The data tier is leveraging an Online Transactional Processing (OLTP) database. What services should you leverage to enable an elastic and scalable web tier?

NEW QUESTION 5
Your organization is in the business of architecting complex transactional databases. For a variety of reasons, this has been done on EBS. What is AWS's recommendation for customers who have architected databases using EBS for backups?

• A. Backups to Amazon S3 be performed through the database management system.
• B. Backups to AWS Storage Gateway be performed through the database management system.
• C. If you take regular snapshots no further backups are required.
• D. Backups to Amazon Glacier be performed through the database management syste

Answer: A

Explanation: Data stored in Amazon EBS volumes is redundantly stored in multiple physical locations as part of normal operation of those services and at no additional charge.
However, Amazon EBS replication is stored within the same availability zone, not across multiple zones; therefore, it is highly recommended that you conduct regular snapshots to Amazon S3 for long-term data durability.
For customers who have architected complex transactional databases using EBS, it is recommended that backups to Amazon S3 be performed through the database management system so that distributed transactions and logs can be checkpointed.
AWS does not perform backups of data that are maintained on virtual disks attached to running instances on Amazon EC2.

NEW QUESTION 6
You are using an m1.smaII EC2 Instance with one 300GB EBS volume to host a relational database. You determined that write throughput to the database needs to be increased. Which of the following approaches can help achieve this? Choose 2 answers

• A. Use an array of EBS volumes.
• B. Enable Multi-AZ mode.
• C. Place the instance in an Auto Scaling Groups
• D. Add an EBS volume and place into RAID 5.

Answer: DE

NEW QUESTION 7
When should I choose Provisioned IOPS over Standard RDS storage?

• A. If you use production online transaction processing (OLTP) workloads.
• B. If you have batch-oriented workloads
• C. If you have workloads that are not sensitive to consistent performance

Answer: A

NEW QUESTION 8
Which of the following strategies can be used to control access to your Amazon EC2 instances?

• A. DB security groups
• B. IAM policies
• C. None of these
• D. EC2 security groups

Answer: D

Explanation: IAM policies allow you to specify what actions your IAM users are allowed to perform against your EC2 Instances. However, when it comes to access control, security groups are what you need in order to define and control the way you want your instances to be accessed, and whether or not certain kind of communications are allowed or not.

NEW QUESTION 9
A user is trying to launch a similar EC2 instance from an existing instance with the option "Launch More like this". The AMI ofthe selected instance is deleted. What will happen in this case?

• A. AWS does not need an AMI for the "Launch more like this" option
• B. AWS will launch the instance but will not create a new AMI
• C. AWS will create a new AMI and launch the instance
• D. AWS will throw an error saying that the AMI is deregistered

Answer: D

Explanation: If the user has deregistered the AMI of an EC2 instance and is trying to launch a similar instance with the option "Launch more like this", AWS will throw an error saying that the AMI is deregistered or not available.

NEW QUESTION 13
You are planning and configuring some EBS volumes for an application. In order to get the most performance out of your EBS volumes, you should attach them to an instance with enough to support your volumes.

• A. Redundancy
• B. Storage
• C. Bandwidth
• D. Memory

Answer: C

Explanation: When you plan and configure EBS volumes for your application, it is important to consider the configuration of the instances that you will attach the volumes to. In order to get the most performance out of your EBS volumes, you should attach them to an instance with enough bandwidth to support your volumes, such as an EBS-optimized instance or an instance with 10 Gigabit network connectMty. This is especially important when you use General Purpose (SSD) or Provisioned IOPS (SSD) volumes, or when you stripe multiple volumes together in a RAID configuration.

NEW QUESTION 14
A friend wants you to set up a small BitTorrent storage area for him on Amazon S3. You tell him it is highly unlikely that AWS would allow such a thing in their infrastructure. However you decide to investigate. Which of the following statements best describes using BitTorrent with Amazon S3?

• A. Amazon S3 does not support the BitTorrent protocol because it is used for pirated software.
• B. You can use the BitTorrent protocol but only for objects that are less than 100 GB in size.
• C. You can use the BitTorrent protocol but you need to ask AWS for specific permissions first.
• D. You can use the BitTorrent protocol but only for objects that are less than 5 GB in siz

Answer: D

Explanation: BitTorrent is an open, peer-to-peer protocol for distributing files. You can use the BitTorrent protocol to retrieve any publicly-accessible object in Amazon S3.
Amazon S3 supports the BitTorrent protocol so that developers can save costs when distributing content at high scale. Amazon S3 is useful for simple, reliable storage of any data. The default distribution mechanism for Amazon S3 data is via client/server download. In client/server distribution, the entire object is transferred point-to-point from Amazon S3 to every authorized user who requests that object. While client/server delivery is appropriate for a wide variety of use cases, it is not optimal for everybody. Specifically, the costs of client/server distribution increase linearly as the number of users downloading objects increases. This can make it expensive to distribute popular objects.
BitTorrent addresses this problem by recruiting the very clients that are downloading the object as distributors themselves: Each client downloads some pieces of the object from Amazon S3 and some from other clients, while simultaneously uploading pieces of the same object to other interested "peers." The benefit for publishers is that for large, popular files the amount of data actually supplied by Amazon S3 can be substantially lower than what it would have been sewing the same clients via client/server download. Less data transferred means lower costs for the publisher of the object.
