Q41. A benefits enrollment company is hosting a 3-tier web application running in a VPC on AWS which includes a NAT (Network Address Translation) instance in the public Web tier. There is enough provisioned capacity for the expected workload tor the new fiscal year benefit enrollment period plus some extra overhead Enrollment proceeds nicely for two days and then the web tier becomes unresponsive, upon investigation using CIoudWatch and other monitoring tools it is discovered that there is an extremely large and unanticipated amount of inbound traffic coming from a set of 15 specific IP addresses over port 80 from a country where the benefits company has no customers. The web tier instances are so overloaded that benefit enrollment administrators cannot even SSH into them. Which actMty would be useful in defending against this attack?
A. Create a custom route table associated with the web tier and block the attacking IP addresses from the IGW (Internet Gateway)
B. Change the EIP (Elastic IP Address) of the NAT instance in the web tier subnet and update the Main Route Table with the new EIP
C. Create 15 Security Group rules to block the attacking IP addresses over port 80
D. Create an inbound NACL (Network Access control list) associated with the web tier subnet with deny rules to block the attacking IP addresses
Answer: D
Explanation:
Use AWS Identity and Access Management (IAM) to control who in your organization has permission to create and manage security groups and network ACLs (NACL). Isolate the responsibilities and roles for
better defense. For example, you can give only your network administrators or security ad min the permission to manage the security groups and restrict other roles.
Q42. Amazon RDS provides high availability and failover support for DB instances using .
A. customized deployments
B. Appstream customizations
C. log events
D. MuIti-AZ deployments
Answer: D
Explanation:
Amazon RDS provides high availability and failover support for DB instances using MuIti-AZ deployments. MuIti-AZ deployments for Oracle, PostgreSQL, MySQL, and MariaDB DB instances use Amazon technology, while SQL Server DB instances use SQL Server Mrroring.

Q43. True or False: Manually created DB Snapshots are deleted after the DB Instance is deleted.
A. TRUE
B. FALSE
Answer: A
Q44. Having set up a website to automatically be redirected to a backup website if it fails, you realize that there are different types of failovers that are possible. You need all your resources to be available the majority of the time. Using Amazon Route 53 which configuration would best suit this requirement?
A. Active-active failover.
B. None. Route 53 can't failover.
C. Active-passive failover.
D. Active-active-passive and other mixed configurations.
Answer: A
Explanation:
You can set up a variety of failover configurations using Amazon Route 53 alias: weighted, latency, geolocation routing, and failover resource record sets.
Active-active failover: Use this failover configuration when you want all of your resources to be available the majority of the time. When a resource becomes unavailable, Amazon Route 53 can detect that it's unhealthy and stop including it when responding to queries.
Active-passive failover: Use this failover configuration when you want a primary group of resources to be available the majority of the time and you want a secondary group of resources to be on standby in case all of the primary resources become unavailable. When responding to queries, Amazon Route 53 includes
only the healthy primary resources. If all of the primary resources are unhealthy, Amazon Route 53 begins to include only the healthy secondary resources in response to DNS queries.
Active-active-passive and other mixed configurations: You can combine alias and non-alias resource record sets to produce a variety of Amazon Route 53 behaviors.

Q45. Select a true statement about Amazon EC2 Security Groups (EC2-Classic).
A. After you launch an instance in EC2-Classic, you can't change its security groups.
B. After you launch an instance in EC2-Classic, you can change its security groups only once.
C. After you launch an instance in EC2-Classic, you can only add rules to a security group.
D. After you launch an instance in EC2-Classic, you cannot add or remove rules from a security group.
Answer: A
Explanation:
After you launch an instance in EC2-Classic, you can't change its security groups. However, you can add rules to or remove rules from a security group, and those changes are automatically applied to all instances that are associated with the security group.

Q46. Your company currently has a 2-tier web application running in an on-premises data center. You have experienced several infrastructure failures in the past two months resu Iting in significant financial losses. Your CIO is strongly agreeing to move the application to AWS. While working on achieving buy-in from the other company executives, he asks you to develop a disaster recovery plan to help improve Business continuity in the short term. He specifies a target Recovery Time Objective (RTO) of 4 hours and a Recovery Point Objective (RPO) of 1 hour or less. He also asks you to implement the solution within 2 weeks. Your database is 200GB in size and you have a 20Mbps Internet connection.
How would you do this while minimizing costs?
A. Create an EBS backed private AMI which includes a fresh install of your application. Develop a CIoudFormation template which includes your AMI and the required EC2, AutoScaIing, and ELB resources to support deploying the application across Multiple- Availability-Zones. Asynchronously replicate transactions from your on-premises database to a database instance in AWS across a secure VPN connection.
B. Deploy your application on EC2 instances within an Auto Scaling group across multiple availability zones. Asynchronously replicate transactions from your on-premises database to a database instance in AWS across a secure VPN connection.
C. Create an EBS backed private AMI which includes a fresh install of your application. Setup a script in your data center to backup the local database every 1 hour and to encrypt and copy the resulting file to an 53 bucket using multi-part upload.
D. Install your application on a compute-optimized EC2 instance capable of supporting the application 's average load. Synchronously replicate transactions from your on-premises database to a database instance in AWS across a secure Direct Connect connection.
Answer: A
Explanation:
Overview of Creating Amazon EBS-Backed AMIs
First, launch an instance from an AMI that's similar to the AMI that you'd like to create. You can connect to your instance and customize it. When the instance is configured correctly, ensure data integrity by
stopping the instance before you create an AMI, then create the image. When you create an Amazon EBS-backed AMI, we automatically register it for you.
Amazon EC2 powers down the instance before creating the AMI to ensure that everything on the instance is stopped and in a consistent state during the creation process. If you're confident that your instance is in a consistent state appropriate for AMI creation, you can tell Amazon EC2 not to power down and reboot the instance. Some file systems, such as XFS, can freeze and unfreeze actMty, making it safe to create the image without rebooting the instance.
During the AMI-creation process, Amazon EC2 creates snapshots of your instance's root volume and any other EBS volumes attached to your instance. If any volumes attached to the instance are encrypted, the new AMI only launches successfully on instances that support Amazon EBS encryption. For more information, see Amazon EBS Encryption.
Depending on the size of the volumes, it can take several minutes for the AMI-creation process to complete (sometimes up to 24 hours).You may find it more efficient to create snapshots of your volumes prior to creating your AMI. This way, only small, incremental snapshots need to be created when the AMI is created, and the process completes more quickly (the total time for snapshot creation remains the same). For more information, see Creating an Amazon EBS Snapshot.
After the process completes, you have a new AMI and snapshot created from the root volume of the instance. When you launch an instance using the new AMI, we create a new EBS volume for its root volume using the snapshot. Both the AMI and the snapshot incur charges to your account until you delete them. For more information, see Deregistering Your AMI.
If you add instance-store volumes or EBS volumes to your instance in addition to the root device volume, the block device mapping for the new AMI contains information for these volumes, and the block device mappings for instances that you launch from the new AMI automatically contain information for these volumes. The instance-store volumes specified in the block device mapping for the new instance are new and don't contain any data from the instance store volumes of the instance you used to create the AMI. The data on EBS volumes persists. For more information, see Block Device Mapping.
Q47. My Read Replica appears "stuck" after a MuIti-AZ failover and is unable to obtain or apply updates from the source DB Instance. What do I do?
A. You will need to delete the Read Replica and create a new one to rep lace it.
B. You will need to disassociate the DB Engine and re associate it.
C. The instance should be deployed to Single AZ and then moved to MuIti- AZ once again
D. You will need to delete the DB Instance and create a new one to replace it.
Answer: A
Q48. A user is hosting a website in the US West-1 region. The website has the highest client base from the Asia-Pacific (Singapore / Japan) region. The application is accessing data from S3 before serving it to client. Which of the below mentioned regions gives a better performance for S3 objects?
A. Japan
B. Singapore
C. US East
D. US West-1
Answer: D
Explanation:
Access to Amazon S3 from within Amazon EC2 in the same region is fast. In this aspect, though the client base is Singapore, the application is being hosted in the US West-1 region. Thus, it is recommended that S3 objects be stored in the US-West-1 region.

D. Just one: MySQL.
Answer: A
Q50. A user comes to you and wants access to Amazon CIoudWatch but only wants to monitor a specific LoadBaIancer. Is it possible to give him access to a specific set of instances or a specific LoadBaIancer?
A. No because you can't use IAM to control access to CIoudWatch data for specific resources.
B. Yes. You can use IAM to control access to CIoudWatch data for specific resources.
C. No because you need to be Sysadmin to access CIoudWatch data.
D. Yes. Any user can see all CIoudWatch data and needs no access rights.
Answer: A
Explanation:
Amazon CIoudWatch integrates with AWS Identity and Access Management (IAM) so that you can
specify which CIoudWatch actions a user in your AWS Account can perform. For example, you could create an IAM policy that gives only certain users in your organization permission to use GetMetricStatistics. They could then use the action to retrieve data about your cloud resources.
You can't use IAM to control access to CIoudWatch data for specific resources. For example, you can't give a user access to CIoudWatch data for only a specific set of instances or a specific LoadBaIancer. Permissions granted using IAM cover all the cloud resources you use with CIoudWatch. In addition, you can't use IAM roles with the Amazon CIoudWatch command line tools.
Using Amazon CIoudWatch with IAM doesn't change how you use CIoudWatch. There are no changes to CIoudWatch actions, and no new CIoudWatch actions related to users and access control.
