A user wants to disable connection draining on an existing ELB. Which of the below mentioned statements helps the user disable connection draining on the ELB?
A. The user can only disable connection draining from CLI
B. It is not possible to disable the connection draining feature once enabled
C. The user can disable the connection draining feature from EC2 -> ELB console or from CLI
D. The user needs to stop all instances before disabling connection draining
The Elastic Load Balancer connection draining feature causes the load balancer to stop sending new requests to the back-end instances when the instances are deregistering or become unhealthy, while ensuring that inflight requests continue to be served. The user can enable or disable connection draining from the AWS EC2 console -> ELB or using CLI.

A user has setup a CloudWatch alarm on the EC2 instance for CPU utilization. The user has setup to receive a notification on email when the CPU utilization is higher than 60%. The user is running a virus scan on the same instance at a particular time. The user wants to avoid receiving an email at this time. What should the user do?
A. Remove the alarm
B. Disable the alarm for a while using CLI
C. Modify the CPU utilization by removing the email alert
D. Disable the alarm for a while using the console
Amazon CloudWatch alarm watches a single metric over a time period that the user specifies and performs one or more actions based on the value of the metric relative to a given threshold over a number of time periods. When the user has setup an alarm and it is know that for some unavoidable event the status may change to Alarm, the user can disable the alarm using the DisableAlarmActions API or from the command line mon-disable-alarm-actions.

The compliance department within your multi-national organization requires that all data for your customers that reside in the European Union (EU) must not leave the EU and also
data for customers that reside in the US must not leave the US without explicit authorization.
What must you do to comply with this requirement for a web based profile management application running on EC2?
A. Run EC2 instances in multiple AWS Availability Zones in single Region and leverage an Elastic Load Balancer with session stickiness to route traffic to the appropriate zone to create their profile
B. Run EC2 instances in multiple Regions and leverage Route 53's Latency Based Routing capabilities to route traffic to the appropriate region to create their profile
C. Run EC2 instances in multiple Regions and leverage a third party data provider to determine if a user needs to be redirect to the appropriate region to create their profile
D. Run EC2 instances in multiple AWS Availability Zones in a single Region and leverage a third party data provider to determine if a user needs to be redirect to the appropriate zone to create their profile
Q4. - (Topic 1)
What would happen to an RDS (Relational Database Service) multi-Availability Zone deployment of the primary OB instance fails?
A. The IP of the primary DB instance is switched to the standby OB instance
B. The RDS (Relational Database Service) DB instance reboots
C. A new DB instance is created in the standby availability zone
D. The canonical name record (CNAME) is changed from primary to standby
Q5. - (Topic 3)
A user has launched an EC2 instance store backed instance in the US-East-1a zone. The user created AMI #1 and copied it to the Europe region. After that, the user made a few updates to the application running in the US-East-1a zone. The user makes an AMI#2 after the changes. If the user launches a new instance in Europe from the AMI #1 copy, which of the below mentioned statements is true?
A. The new instance will have the changes made after the AMI copy as AWS just copies the reference of the original AMI during the copying. Thus, the copied AMI will have all the updated data
B. The new instance will have the changes made after the AMI copy since AWS keeps updating the AMI
C. It is not possible to copy the instance store backed AMI from one region to another
D. The new instance in the EU region will not have the changes made after the AMI copy
Within EC2, when the user copies an AMI, the new AMI is fully independent of the source AMI; there is no link to the original (source. AMI. The user can modify the source AMI without affecting the new AMI and vice a versa. Therefore, in this case even if the source AMI is modified, the copied AMI of the EU region will not have the changes. Thus, after copy the user needs to copy the new source AMI to the destination region to get those changes.
Q6. - (Topic 2)
A user has created a VPC with CIDR 188.8.131.52/16. The user has created public and VPN only subnets along with hardware VPN access to connect to the user’s datacenter. The user wants to make so that all traffic coming to the public subnet follows the organization’s proxy policy. How can the user make this happen?
A. Setting up a NAT with the proxy protocol and configure that the public subnet receives traffic from NAT
B. Settin up a proxy policy in the internet gateway connected with the public subnet
C. It is not possible to setup the proxy policy for a public subnet
D. Setting the route table and security group of the public subnet which receives traffic from a virtual private gateway
The user can create subnets within a VPC. If the user wants to connect to VPC from his own data centre, he can setup public and VPN only subnets which uses hardware VPN access to connect with his data centre. When the user has configured this setup, it will update the main route table used with the VPN-only subnet, create a custom route table and associate it with the public subnet. It also creates an internet gateway for the public subnet. By default the internet traffic of the VPN subnet is routed to a virtual private gateway while the internet traffic of the public subnet is routed through the internet gateway. The user can set up the route and security group rules. These rules enable the traffic to come from the organization’s network over the virtual private gateway to the public subnet to allow proxy settings on that public subnet.
Q7. - (Topic 3)
A user has configured ELB with SSL using a security policy for secure negotiation between the client and load balancer. Which of the below mentioned SSL protocols is not supported by the security policy?
A. TLS 1.3
B. TLS 1.2
C. SSL 2.0
D. SSL 3.0
Elastic Load Balancing uses a Secure Socket Layer (SSL. negotiation configuration which is known as a Security Policy. It is used to negotiate the SSL connections between a client and the load balancer. Elastic Load Balancing supports the following versions of the SSL protocol: TLS 1.2 TLS 1.1 TLS 1.0 SSL 3.0 SSL 2.0
Q8. - (Topic 2)
An organization wants to move to Cloud. They are looking for a secure encrypted database storage option. Which of the below mentioned AWS functionalities helps them to achieve this?
A. AWS MFA with EBS
B. AWS EBS encryption
C. Multi-tier encryption with Redshift
D. AWS S3 server side storage
AWS EBS supports encryption of the volume while creating new volumes. It also supports creating volumes from existing snapshots provided the snapshots are created from encrypted volumes. The data at rest, the I/O as well as all the snapshots of EBS will be encrypted. The encryption occurs on the servers that host the EC2 instances, providing encryption of data as it moves between the EC2 instances and EBS storage. EBS encryption is based on the AES-256 cryptographic algorithm, which is the industry standard

An AWS account wants to be part of the consolidated billing of his organization’s payee account. How can the owner of that account achieve this?
A. The payee account has to request AWS support to link the other accounts with his account
B. The owner of the linked account should add the payee account to his master account list from the billing console
C. The payee account will send a request to the linked account to be a part of consolidated billing
D. The owner of the linked account requests the payee account to add his account to consolidated billing
AWS consolidated billing enables the organization to consolidate payments for multiple Amazon Web Services (AWS. accounts within a single organization by making a single paying account. To add a particular account (linked. to the master (payee. account, the payee account has to request the linked account to join consolidated billing. Once the linked account accepts the request henceforth all charges incurred by the linked account will be paid by the payee account.

A user has created a subnet with VPC and launched an EC2 instance in that subnet with only default settings.Which of the below mentioned options is ready to use on the EC2
instance as soon as it is launched?
A. Elastic IP
B. Private IP
C. Public IP
D. I nternet gateway
A Virtual Private Cloud (VPC. is a virtual network dedicated to a user’s AWS account. A subnet is a range of IP addresses in the VPC. The user can launch the AWS resources into a subnet. There are two supported platforms into which a user can launch instances: EC2-Classic and EC2-VPC. When the user launches an instance which is not a part of the non-default subnet, it will only have a private IP assigned to it. The instances part of a subnet can communicate with each other but cannot communicate over the internet or to the AWS services, such as RDS / S3.
