Question 253
An organization is planning to host a web application in the AWS VPC. The organization does not want to host a database in the public cloud due to statutory requirements.
How can the organization setup in this scenario?
A. The organization should plan the app server on the public subnet and database in the organization's data center and connect them with the VPN gateway.
B. The organization should plan the app server on the public subnet and use RDS with the private subnet for a secure data operation.
C. The organization should use the public subnet for the app server and use RDS with a storage gateway to access as well as sync the data securely from the local data center.
D. The organization should plan the app server on the public subnet and database in a private subnet so it will not be in the public cloud.
Question 254
A user is trying to create a PIOPS EBS volume with 4000 IOPS and 100 GB size. AWS does not allow the user to create this volume.
What is the possible root cause for this?
A. PIOPS is supported for EBS higher than 500 GB size
B. The maximum IOPS supported by EBS is 3000
C. The ratio between IOPS and the EBS volume is higher than 30
D. The ratio between IOPS and the EBS volume is lower than 50
Question 255
A user is planning to host a Highly Available system on the AWS VPC. Which of the below mentioned statements is helpful in this scenario?
A. Create VPC subnets in two separate availability zones and launch instances in different subnets.
B. Create VPC with only one public subnet and launch instances in different AZs using that subnet.
C. Create two VPCs in two separate zones and setup failover with ELB such that if one VPC fails it will divert traffic to another VPC.
D. Create VPC with only one private subnet and launch instances in different AZs using that subnet.
Question 256
A user is creating a PIOPS volume. What is the maximum ratio the user should configure between PIOPS and the volume size?
A. 5
B. 10
C. 20
D. 30
Question 257
What is a possible reason you would need to edit claims issued in a SAML token?
A. The NameIdentifier claim cannot be the same as the username stored in AD.
B. Authentication fails consistently.
C. The NameIdentifier claim cannot be the same as the claim URI.
D. The NameIdentifier claim must be the same as the username stored in AD.
Question 258
A government client needs you to set up secure cryptographic key storage for some of their extremely confidential data. You decide that the AWS CloudHSM is the best service for this.
However, there seem to be a few pre-requisites before this can happen, one of those being a security group that has certain ports open.
Which of the following is correct in regards to those security groups?
A. A security group that has no ports open to your network.
B. A security group that has only port 3389 (for RDP) open to your network.
C. A security group that has only port 22 (for SSH) open to your network.
D. A security group that has port 22 (for SSH) or port 3389 (for RDP) open to your network.
Question 259
What is the network performance offered by the c4.
8xlarge instance in Amazon EC2?
A. Very High but variable
B. 20 Gigabit
C. 5 Gigabit
D. 10 Gigabit
Question 260
An organization is setting up a web application with the JEE stack. The application uses the JBoss app server and MySQL DB. The application has a logging module which logs all the activities whenever a business function of the JEE application is called. The logging activity takes some time due to the large size of the log file.
If the application wants to setup a scalable infrastructure which of the below mentioned options will help achieve this setup?
A. Host the log files on EBS with PIOPS which will have higher I/O.
B. Host logging and the app server on separate servers such that they are both in the same zone.
C. Host logging and the app server on the same instance so that the network latency will be shorter.
D. Create a separate module for logging and using SQS compartmentalize the module such that all calls to logging are asynchronous.
