Identify a true statement about the statement ID (Sid) in IAM.

1. A. You cannot expose the Sid in the IAM API.
2. B. You cannot use a Sid value as a sub-ID for a policy document's ID for services provided by SQS and SNS.
3. C. You can expose the Sid in the IAM API.
4. D. You cannot assign a Sid value to each statement in a statement arra

Correct Answer: A
The Sid(statement ID) is an optional identifier that you provide for the policy statement. You can assign a Sid a value to each statement in a statement array. In IAM, the Sid is not exposed in the IAM API. You can't retrieve a particular statement based on this ID.

Refer to the architecture diagram above of a batch processing solution using Simple Queue Service (SQS) to set up a message queue between EC2 instances which are used as batch processors Cloud Watch monitors the number of Job requests (queued messages) and an Auto Scaling group adds or deletes batch sewers automatically based on parameters set in Cloud Watch alarms. You can use this architecture to implement which of the following features in a cost effective and efficient manner?

1. A. Reduce the overall lime for executing jobs through parallel processing by allowing a busy EC2 instance that receives a message to pass it to the next instance in a daisy-chain setup.
2. B. Implement fault tolerance against EC2 instance failure since messages would remain in SQS and worn can continue with recovery of EC2 instances implement fault tolerance against SQS failure by backing up messages to S3.
3. C. Implement message passing between EC2 instances within a batch by exchanging messages throughSQS.
4. D. Coordinate number of EC2 instances with number of job requests automatically thus Improving cost effectiveness.
5. E. Handle high priority jobs before lower priority jobs by assigning a priority metadata field to SQS messages.

Correct Answer: D

An organization has created 5 IAM users. The organization wants to give them the same login ID but different passwords. How can the organization achieve this?

1. A. The organization should create each user in a separate region so that they have their own URL to login
2. B. The organization should create a separate login ID but give the IAM users the same alias so that each one can login with their alias
3. C. It is not possible to have the same login ID for multiple IAM users of the same account
4. D. The organization should create various groups and add each user with the same login ID to different group
5. E. The user can login with their own group ID

Correct Answer: C
AWS Identity and Access Management is a web service which allows organizations to manage users and user permissions for various AWS services. Whenever the organization is creating an IAM user, there should be a unique ID for each user. It is not possible to have the same login ID for multiple users. The names of users, groups, roles, instance profiles must be alphanumeric, including the following common characters: plus (+), equal (=), comma (,), period (.), at (@), and dash (-).

True or False: In Amazon EIastiCache replication groups of Redis, for performance tuning reasons, you can change the roles of the cache nodes within the replication group, with the primary and one of the replicas exchanging roles.

1. A. True, however, you get lower performance.
2. B. FALSE
3. C. TRUE
4. D. False, you must recreate the replication group to improve performance tunin

Correct Answer: C
In Amazon EIastiCache, a replication group is a collection of Redis Cache Clusters, with one primary read-write cluster and up to five secondary, read-only clusters, which are called read replicas. You can change the roles of the cache clusters within the replication group, with the primary cluster and one of the replicas exchanging roles. You might decide to do this for performance tuning reasons.

Your company is in the process of developing a next generation pet collar that collects biometric information to assist families with promoting healthy lifestyles for their pets Each collar will push 30kb of biometric data In JSON format every 2 seconds to a collection platform that will process and analyze the data providing health trending information back to the pet owners and veterinarians via a web portal Nlanagement has tasked you to architect the collection platform ensuring the following requirements are met.
Provide the ability for real-time analytics of the inbound biometric data Ensure processing of the biometric data is highly durable. Elastic and parallel The results of the analytic processing should be persisted for data mining
Which architecture outlined below win meet the initial requirements for the collection platform?

1. A. Utilize S3 to collect the inbound sensor data analyze the data from S3 with a daily scheduled Data Pipeline and save the results to a Redshift Cluster.
2. B. Utilize Amazon Kinesis to collect the inbound sensor data, analyze the data with Kinesis clients and save the results to a Redshift cluster using EMR.
3. C. Utilize SQS to collect the inbound sensor data analyze the data from SQS with Amazon Kinesis and save the results to a Microsoft SQL Server RDS instance.
4. D. Utilize EMR to collect the inbound sensor data, analyze the data from EUR with Amazon Kinesis and save me results to DynamoDB.

Correct Answer: B
