Is this possible? A.    No. However if you have 2 AWS accounts this can be doneB.    No. AWS Elastic Beanstalk is not designed to support multiple running environmentsC.    Yes. AWS Elastic Beanstalk is designed to support a number of multiple running environmentsD.    Yes. However AWS Elastic Beanstalk is designed to support only 2 multiple running environments Answer: CExplanation:AWS Elastic Beanstalk is designed to support multiple running environments. As an example you could have one for integration testing, one for pre-production, and one for production, with each environment independently configured and running on its own separate AWS resources.https://aws.amazon.com/elasticbeanstalk/faqs/ QUESTION 22A user has launched an EBS backed Linux instance. How can a user detach the root device and attach it to another instance as a secondary volume? A.    Unmount the root volume first and then detach itB.    It is not possible to mount the root volume to some other instanceC.    Stop the first instance and then attach instance's root volume as a new volume to the other instanceD.    It is not possible to mount the root device as a secondary volume on the other instance Answer: CExplanation:If an Amazon EBS volume is the root device of an instance, it cannot be detached unless the instance is in the stopped state.http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-detaching-volume.html QUESTION 23When using Amazon SQS how much data can you store in a message? A.    8 KBB.    2 KBC.    16 KBD.    4 KB Answer: AExplanation:With Amazon SQS version 2008-01-01, the maximum message size for both SOAP and Query requests is 8KB. If you need to send messages to the queue that are larger than 8 KB, AWS recommends that you split the information into separate messages. Alternatively, you could use Amazon S3 or Amazon SimpleDB to hold the information and include the pointer to that information in the Amazon SQS message. If you send a message that is larger than 8KB to the queue, you will receive a MessageTooLong error with HTTP code 400.https://aws.amazon.com/items/1343?externalID=1343 QUESTION 24A 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 regionB.    Open the security group of the US West region in the RDS security group's ingress ruleC.    Configure the IP range of the US West region instance as the ingress security rule of RDSD.    Create an IAM role which has access to RDS and launch an instance in the US West region with it Answer: CExplanation: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.http://docs.aws.amazon.com/AmazonRDS/latest/UserGuide/USER_WorkingWithSecurityGroups.html QUESTION 25In regard to AWS CloudFormation, what is a stack? A.    The set of AWS templates that are created and managed as a templateB.    The set of AWS resources that are created and managed as a templateC.    The set of AWS resources that are created and managed as a single unitD.    The set of AWS templates that are created and managed as a single unit Answer: CExplanation:A stack is the set of AWS resources that are created and managed as a single unit when AWS CloudFormation initiates a template.http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/concept-stack.html QUESTION 26In regard to DynamoDB, what is the Global secondary index? A.    An index with a hash and range key that can be different from those on the tableB.    An index that has the same range key as the table, but a different hash keyC.    An index that has the same hash key and range key as the tableD.    An index that has the same hash key as the table, but a different range key Answer: AExplanation:Global secondary index -- an index with a hash and range key that can be different from those on the table.http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/DataModel.html QUESTION 27Which of the below mentioned options is not a best practice to securely manage the AWS access credentials? A.    Enable MFA for privileged usersB.    Create individual IAM usersC.    Keep rotating your secure access credentials at regular intervalsD.    Create strong access key and secret access key and attach to the root account Answer: DExplanation:It is a recommended approach to avoid using the access and secret access keys of the root account. Thus, do not download or delete it. Instead make the IAM user as powerful as the root account and use its credentials. The user cannot generate their own access and secret access keys as they are always generated by AWS.http://docs.aws.amazon.com/IAM/latest/UserGuide/IAMBestPractices.html QUESTION 28You have been given a scope to deploy some AWS infrastructure for a large organisation. The requirements are that you will have a lot of EC2 instances but may need to add more when the average utilization of your Amazon EC2 fleet is high and conversely remove them when CPU utilization is low. Which AWS services would be best to use to accomplish this? A.    Amazon CloudFront, Amazon CloudWatch and Elastic Load Balancing.B.    Auto Scaling, Amazon CloudWatch and AWS CloudTrail.C.    Auto Scaling, Amazon CloudWatch and Elastic Load Balancing.D.    Auto Scaling, Amazon CloudWatch and AWS Elastic Beanstalk. Answer: CExplanation:Auto Scaling enables you to follow the demand curve for your applications closely, reducing the need to manually provision Amazon EC2 capacity in advance. For example, you can set a condition to add new Amazon EC2 instances in increments to the Auto Scaling group when the average utilization of your Amazon EC2 fleet is high; and similarly, you can set a condition to remove instances in the same increments when CPU utilization is low. If you have predictable load changes, you can set a schedule through Auto Scaling to plan your scaling activities. You can use Amazon CloudWatch to send alarms to trigger scaling activities and Elastic Load Balancing to help distribute traffic to your instances within Auto Scaling groups. Auto Scaling enables you to run your Amazon EC2 fleet at optimal utilization.http://aws.amazon.com/autoscaling/ QUESTION 29You are building an online store on AWS that uses SQS to process your customer orders. Your backend system needs those messages in the same sequence the customer orders have been put in. How can you achieve that? A.    You can do this with SQS but you also need to use SWFB.    Messages will arrive in the same order by defaultC.    You can use sequencing information on each messageD.    It is not possible to do this with SQS Answer: CExplanation:Amazon SQS is engineered to always be available and deliver messages. One of the resulting tradeoffs is that SQS does not guarantee first in, first out delivery of messages. For many distributed applications, each message can stand on its own, and as long as all messages are delivered, the order is not important. If your system requires that order be preserved, you can place sequencing information in each message, so that you can reorder the messages when the queue returns them.http://docs.aws.amazon.com/AWSSimpleQueueService/latest/SQSDeveloperGuide/Welcome.html QUESTION 30A user has launched an EC2 instance and installed a website with the Apache webserver. The webserver is running but the user is not able to access the website from the internet. What can be the possible reason for this failure? A.    The security group of the instance is not configured properly.B.    The instance is not configured with the proper key-pairs.C.    The Apache website cannot be accessed from the internet.D.    Instance is not configured with an elastic IP. Answer: AExplanation:In Amazon Web Services, when a user has configured an instance with Apache, the user needs to ensure that the ports in the security group are opened as configured in Apache config. E.g. If Apache is running on port 80, the user should open port 80 in the security group.http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-network-security.html QUESTION 31When you use the AWS Elastic Beanstalk console to deploy a new application you'll need to upload a source bundle and it should ____. A.    Consist of a single .zip fileB.    Consist of a single .war fileC.    Consist of a single .zip file or .war fileD.    Consist of a folder with all files Answer: CExplanation:When you use the AWS Elastic Beanstalk console to deploy a new application or an application version, you'll need to upload a source bundle. Your source bundle must meet the following requirements:Consist of a single .zip file or .war fileNot exceed 512 MBNot include a parent folder or top-level directory (subdirectories are fine)http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/using-features.deployment.source.html QUESTION 32A user had defined an IAM policy similar to the one given below on a bucket:{"Version": "2012-10-17","Statement": [{"Effect": "Allow","Principal": {"AWS": "arn:aws:iam::12112112:user/test"},"Action": ["s3:GetBucketLocation","s3:ListBucket","s3:GetObject"],"Resource": ["arn:aws:s3:::passleader"]}]}What will this do? A.    It will result in an error saying invalid policy statementB.    It will create an IAM policy for the user testC.    Allows the user test of the AWS account ID 12112112 to perform GetBucketLocation, ListBucket and GetObject on the bucket passleaderD.    It will allow all the IAM users of the account ID 12112112 to perform GetBucketLocation, ListBucket and GetObject on bucket passleader Answer: CExplanation:The IAM policy allows to test a user in the account 12112112 to perform:s3:GetBucketLocations3:ListBuckets3:GetObjectAmazon S3 permissions on the passleader bucket.http://docs.aws.amazon.com/AmazonS3/latest/dev/access-policy-language-overview.html QUESTION 33A user has configured a bucket S3 to host a static website. What difference will there be when static website hosting is enabled? A.    It will help the user identify this bucket as the website root to map with the domainB.    It will create a new version of the bucketC.    It will not make any difference, but will help the user to configure the error pageD.    It will provide the region specific website endpoint Answer: DExplanation:To host a static website, the user needs to configure an Amazon S3 bucket for website hosting and then upload the website contents to the bucket. The website is then available at the region-specific website endpoint of the bucket.http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteHosting.html QUESTION 34How does Amazon SQS allow multiple readers to access the same message queue without losing messages or processing them many times? A.    By identifying a user by his unique idB.    By using unique cryptographyC.    Amazon SQS queue has a configurable visibility timeoutD.    Multiple readers can't access the same message queue Answer: CExplanation:Every Amazon SQS queue has a configurable visibility timeout. For the designated amount of time after a message is read from a queue, it will not be visible to any other reader. As long as the amount of time that it takes to process the message is less than the visibility timeout, every message will be processed and deleted. In the event that the component processing the message fails or becomes unavailable, the message will again become visible to any component reading the queue once the visibility timeout ends. This allows you to have many components all reading messages from the same queue, with each working to process different messages.https://aws.amazon.com/sqs/faqs/ QUESTION 35In DynamoDB, a secondary index is a data structure that contains a subset of attributes from a table, along with an alternate key to support ____ operations. A.    None of the aboveB.    BothC.    QueryD.    Scan Answer: CExplanation:In DynamoDB, a secondary index is a data structure that contains a subset of attributes from a table, along with an alternate key to support Query operations.http://docs.aws.amazon.com/amazondynamodb/latest/developerguide/SecondaryIndexes.html QUESTION 36A user is trying to understand AWS SNS. To which of the below mentioned end points is SNS unable to send a notification? A.    AWS SESB.    Email JSONC.    AWS SQSD.    HTTP Answer: AExplanation:Amazon Simple Notification Service (Amazon SNS) is a fast, flexible, and fully managed push messaging service. Amazon SNS can deliver notifications by SMS text message or email to the Amazon Simple Queue Service (SQS) queues or to any HTTP endpoint. The user can select one the following transports as part of the subscription requests: "HTTP", "HTTPS","Email", "Email-JSON", "SQS", "and SMS".http://aws.amazon.com/sns/faqs/ QUESTION 37Which of the following device names is recommended for an EBS volume that can be attached to an Amazon EC2 Instance running Windows? A.    xvd[a-e]B.    /mnt/sd[b-e]C.    xvd[f-p]D.    /dev/sda1 Answer: CExplanation:The xvd[f-p] is the recommended device name for EBS volumes that can be attached to the Amazon EC2 Instances running on Windows.http://docs.aws.amazon.com/AWSEC2/latest/WindowsGuide/device_naming.html QUESTION 38Can one instance be registered with two ELBs in the same region? A.    NoB.    Yes, provided both ELBs have the same health check configurationC.    Yes, alwaysD.    Yes, provided both ELBs are in the same AZ Answer: CExplanation:Yes, it is possible to have one instance part of two separate ELBs, though both ELBs have different configurations. ELBs are never launched in specific zones.http://docs.aws.amazon.com/ElasticLoadBalancing/latest/DeveloperGuide/enable-disable-az.html QUESTION 39What does Amazon SQS provide? A.    An asynchronous message queue service.B.    A Simple Query Server, managed directly by Amazon Web Services.C.    None of these.D.    A synchronous message queue service. Answer: AExplanation:Amazon SQS stands for Simple Queue Services, and provides a cost-effective way to decouple the components of your application through an asynchronous message queue service.http://aws.amazon.com/sqs/ QUESTION 40A user is trying to create a list of IAM users with the AWS console. When the IAM users are created which of the below mentioned credentials will be enabled by default for the user? A.    IAM access key and secret access keyB.    IAM X.509 certificatesC.    Nothing. Everything is disabled by defaultD.    IAM passwords Answer: CExplanation:Newly created IAM users have no password and no access key (access key ID and secret access key). If the user needs to administer your AWS resources using the AWS Management Console, you can create a password for the user. If the user needs to interact with AWS programmatically (using the command line interface (CLI), the AWS SDK, or service-specific APIs), you can create an access key for that user. The credentials you create for users are what they use to uniquely identify themselves to AWS.http://docs.aws.amazon.com/IAM/latest/UserGuide/Using_WorkingWithGroupsAndUsers.html Download the newest PassLeader AWS Certified Developer – Associate dumps from passleader.com now! 100% Pass Guarantee!
