Q263. You have been asked to build AWS infrastructure for disaster recovery for your local applications and within that you should use an AWS Storage Gateway as part of the solution. Which of the following best describes the function of an AWS Storage Gateway?
A. Accelerates transferring large amounts of data between the AWS cloud and portable storage devices .
B. A web service that speeds up distribution of your static and dynamic web content.
C. Connects an on-premises software appliance with cloud-based storage to provide seamless and secure integration between your on-premises IT environment and AWS's storage infrastructure.
D. Is a storage service optimized for infrequently used data, or "cold data."
Answer: C
Explanation:
AWS Storage Gateway connects an on-premises software appliance with cloud-based storage to provide seamless integration with data security features between your on-premises IT environment and the Amazon Web Services (AWS) storage infrastructure. You can use the service to store data in the AWS cloud for scalable and cost-effective storage that helps maintain data security. AWS Storage Gateway offers both volume-based and tape-based storage solutions:
Volume gateways Gateway-cached volumes Gateway-stored volumes
Gateway-virtual tape library (VTL)

B. Free Storage Space
C. Free Storage Volume
D. Free DB Storage Space
Answer: B
Q265. Just when you thought you knew every possible storage option on AWS you hear someone mention Reduced Redundancy Storage (RRS) within Amazon S3. What is the ideal scenario to use Reduced Redundancy Storage (RRS)?
A. Huge volumes of data
B. Sensitve data
C. Non-critical or reproducible data
D. Critical data
Answer: C
Explanation:
Reduced Redundancy Storage (RRS) is a new storage option within Amazon S3 that enables customers to reduce their costs by storing non-critical, reproducible data at lower levels of redundancy than Amazon S3’s standard storage. RRS provides a lower cost, less durable, highly available storage option that is designed to sustain the loss of data in a single facility.
RRS is ideal for non-critical or reproducible data.
For example, RRS is a cost-effective solution for sharing media content that is durably stored elsewhere. RRS also makes sense if you are storing thumbnails and other resized images that can be easily reproduced from an original image.

Q268. You are building infrastructure for a data warehousing solution and an extra request has come through that there will be a lot of business reporting queries running all the time and you are not sure if your current DB instance will be able to handle it. What would be the best solution for this?
A. DB Parameter Groups
B. Read Replicas
C. Multi-AZ DB Instance deployment
D. Database Snapshots
Answer: B
Explanation:
Read Replicas make it easy to take advantage of MySQL’s built-in replication functionality to elastically scale out beyond the capacity constraints of a single DB Instance for read-heavy database workloads. There are a variety of scenarios where deploying one or more Read Replicas for a given source DB Instance may make sense. Common reasons for deploying a Read Replica include:
Scaling beyond the compute or I/O capacity of a single DB Instance for read-heavy database workloads. This excess read traffic can be directed to one or more Read Replicas.
Serving read traffic while the source DB Instance is unavailable. If your source DB Instance cannot take I/O requests (e.g. due to I/O suspension for backups or scheduled maintenance), you can direct read traffic to your Read RepIica(s). For this use case, keep in mind that the data on the Read Replica may be "staIe" since the source DB Instance is unavailable.
Business reporting or data warehousing scenarios; you may want business reporting queries to run against a Read Replica, rather than your primary, production DB Instance.

Q269. You are building a system to distribute confidential documents to employees. Using CIoudFront, what method could be used to serve content that is stored in S3, but not publically accessible from S3 directly?
A. Add the CIoudFront account security group "amazon-cf/amazon-cf-sg" to the appropriate S3 bucket policy.
B. Create a S3 bucket policy that lists the C|oudFront distribution ID as the Principal and the target bucket as the Amazon Resource Name (ARN).
C. Create an Identity and Access Management (IAM) User for CIoudFront and grant access to the objects in your S3 bucket to that IAM User.
D. Create an Origin Access Identity (OAI) for CIoudFront and grant access to the objects in your S3 bucket to that OAI.
Answer: D
Explanation:
You restrict access to Amazon S3 content by creating an origin access identity, which is a special CIoudFront user. You change Amazon S3 permissions to give the origin access identity permission to access your objects, and to remove permissions from everyone else. When your users access your Amazon S3 objects using CIoudFront URLs, the CIoudFront origin access identity gets the objects on your users' behalf. If your users try to access objects using Amazon S3 URLs, they're denied access. The origin access identity has permission to access objects in your Amazon S3 bucket, but users don't. Reference:

Q270. A user is launching an EC2 instance in the US East region. Which of the below mentioned options is recommended by AWS with respect to the selection of the availability zone?
A. Always select the AZ while launching an instance
B. Always select the US-East-1-a zone for HA
C. Do not select the AZ; instead let AWS select the AZ
D. The user can never select the availability zone while launching an instance
Answer: C
Explanation:
When launching an instance with EC2, AWS recommends not to select the availability zone (AZ). AWS specifies that the default Availability Zone should be accepted. This is because it enables AWS to select the best Availability Zone based on the system health and available capacity. If the user launches additional instances, only then an Availability Zone should be specified. This is to specify the same or different AZ from the running instances.
