In Amazon SWF, the limit for open activity tasks is up to ______ per workflow execution. 10,000 1000 500 5000 2 / 20 2. A user wants to access RDS from an EC2 instance using IP addresses. Both RDS and EC2 are in the same region, but different Availability Zone. Which of the below-mentioned options help configure that the instance is accessed faster? Configure the Private IP of the Instance in RDS security group Configure the Public IP of the instance in RDS security group Security group of EC2 allowed in the RDS security group Configuring the elastic IP of the instance in RDS security group 3 / 20 3. An ELB is diverting traffic across 5 instances. One of the instances was unhealthy only for 20 minutes. What will happen after 20 minutes when the instance becomes healthy? ELB will not automatically send traffic to the same instance. However, the user can configure to start sending traffic to the same instance ELB will never divert traffic back to the same instance ELB starts sending traffic to the instance once it is healthy ELB terminates the instance once it is unhealthy. Thus, the instance cannot be healthy after 10 minutes 4 / 20 4. DynamoDB does not support increment or decrement atomic operations: True False 5 / 20 5. You have been told by your security officer of KnowledgeHut that you need to give a presentation on encryption on data at rest on AWS to 50 of your co-workers. You feel like you understand this extremely well regarding data stored on AWS S3 so you aren’t too concerned, but you begin to panic a little when you realize you also probably need to talk about encryption on data stored on your databases, namely Amazon RDS. Regarding Amazon RDS encryption, which of the following statements is the truest Encryption can be enabled on RDS instances to encrypt the underlying storage, and this will by default also encrypt snapshots as they are created. No additional configuration needs to be made on the client side for this to work. Encryption cannot be enabled on RDS instances unless the keys are not managed by KMS. Encryption can be enabled on RDS instances to encrypt the underlying storage, and this will by default also encrypt snapshots as they are created. However, some additional configuration needs to be made on the client side for this to work. Encryption can be enabled on RDS instances to encrypt the underlying storage, but you cannot encrypt snapshots as they are created. 6 / 20 6. You have a legacy app running and it uses an m4.large instance size and cannot scale with Auto Scaling, but only has peak performance 5% of the time. This is a huge waste of resources and money so your Senior Technical Solution Architect has set you the task of trying to reduce costs while still keeping the legacy application running as it should. Which of the following would best accomplish the task your manager has set you? Use a C4.large instance with enhanced networking. Use t2.nano instance and add spot instances when they are required. Use two t2.nano instances that have single Root I/O Virtualization Use a T2 burstable performance instance. 7 / 20 7. Which one of the following operations is NOT a DynamoDB operation? DescribeTable BatchDeleteItem BatchWriteItem BatchGetItem 8 / 20 8. True or False: In DynamoDB, Scan operations are always eventually consistent. No because you can optionally request strongly consistent scan. No because scan is strongly consistent by default No because scan is like Query operation Yes 9 / 20 9. Can a user get a notification of each instance start / terminate configured with Auto Scaling? Yes, if configured with the Launch Config No Yes, always Yes, if configured with the Auto Scaling group 10 / 20 10.

One of your colleagues in Knowledge Hut has just left and you have been handed some of the infrastructure he set up. In one of the setups you start looking at, he has created multiple components of a single application and all the components are hosted on a single EC2 instance (without an ELB) in a VPC. You have been told that this needs to be set up with two separate SSLs for each component. Which of the following would best achieve the setting up off the two separate SSLs while using still only using one EC2 instance? Create an EC2 instance with a NAT address. Create an EC2 instance which has multiple subnets attached to it and each will have a separate IP address. Create an EC2 instance which has both an ACL and the security group attached to it and have separate rules for each IP address. Create an EC2 instance which has multiple network interfaces with multiple elastic IP addresses. 13 / 20 13. A developer has created a new EBS volume from an existing snapshot. The snapshot size shows 10 GB. Can he now create a volume of 30 GB from that snapshot? Provided the original volume has set the change size attribute to true Provided the snapshot has the modify size attribute set as true Yes No 14 / 20 14. How many queues and messages can you have per queue for each user in Amazon SQS? 512 10 Unlimited 1000 15 / 20 15. A user has launched an RDS instance. The user has created 3 databases on the same server. What can the maximum size be for each database? The total instance storage size cannot be more than 3 TB The size of each DB cannot be more than 1 TB It is not possible to have more than one DB on a single instance The size of each DB cannot be more than 3 TB 16 / 20 16.
