Question 11

A user has created an application which sends data to a log file. The server hosting the log files can be unavailable due to any reason. The user wants to make it so that whenever the log server is up it should be receMng the messages. Which of the below mentioned AWS services helps achieve this functionality?

A. AWS Simple Workflow
B. AWS Simple Task Service
C. AWS Simple Notification Service
D. AWS Simple Queue Service

Correct Answer:D
Amazon Simple Queue Service (SQS) is a fast, reliable, scalable, and fully managed message queuing service. SQS provides a simple and cost-effective way to decouple the components of an application. The user can use SQS to transmit any volume of data without losing messages or requiring other services to always be available. Using SQS, the application has to just send the data to SQS and SQS transmits it to the log file whenever it is available.

Question 13

A user is planning to host a web server as well as an app server on a single EC2 instance which is a part of the public subnet of a VPC. How can the user setup to have two separate public IPs and separate security groups for both the application as well as the web server?

A. Launch a VPC instance with two network interface
B. Assign a separate security group to each and AWS will assign a separate public IP to them.
C. Launch VPC with two separate subnets and make the instance a part of both the subnets.
D. Launch a VPC instance with two network interface
E. Assign a separate security group and elastic IP to them.
F. Launch a VPC with ELB such that it redirects requests to separate VPC instances of the public subne

Correct Answer:C
If you need to host multiple websites(with different IPs) on a single EC2 instance, the following is the suggested method from AWS.
Launch a VPC instance with two network interfaces
Assign elastic IPs from VPC EIP pool to those interfaces (Because, when the user has attached more than one network interface with an instance, AWS cannot assign public IPs to them.)
Assign separate Security Groups if separate Security Groups are needed
This scenario also helps for operating network appliances, such as firewalls or load balancers that have multiple private IP addresses for each network interface.

C. Create an IAM policy and define the region in the condition

Question 15

A user has launched one EC2 instance in the US West region. The user wants to access the RDS instance launched in the US East region from that EC2 instance. How can the user configure the access for that EC2 instance?

A. It is not possible to access RDS of the US East region from the US West region
B. Open the security group of the US West region in the RDS security group’s ingress rule
C. Configure the IP range of the US West region instance as the ingress security rule of RDS
D. Create an IAM role which has access to RDS and launch an instance in the US West region with it

Correct Answer:C
The user cannot authorize an Amazon EC2 security group if it is in a different AWS Region than the RDS DB instance. The user can authorize an IP range or specify an Amazon EC2 security group in the same region that refers to an IP address in another region.
