  1. Sean Leans says:

    Hi! I just took the AWS-SysOps exam few days ago and luckily passed with 90% marks (the passing score is 65% now). I had 55 single choice and multiple choice questions in total, most of them were single answer questions. And, questions on Monitoring and Metrics,

    Deployment and Provisioning were not easy to answer, other questions on High Availability and Data Management and Analysis were very easy to get the correct answers.

    I learned valid AWS-SysOps dumps here — https://drive.google.com/open?id=0B-ob6L_QjGLpUWdPWXRHaERYWlU (recommend you to get the full version 310q AWS-SysOps dumps), all actual AWS-SysOps exam questions were from that 310q AWS-SysOps dumps.

    Good Luck, my cool guy!

      My advice is to take an online course like acloudguru (this is for knowledge) AND running through the questions (this is just to pass but you may still know nothing) in this site is enough to ensure a good passing mark

        Advice taken, I’ve been using acloudguru both from Udemy and https://acloud.guru, and running through these questions. I also took a practice exam, and it has the same questions on the real Developer Associate exam, which I hope to pass this time.

    New AWS Certified SysOps Administrator – Associate Exam Questions and Answers Updated Recently (18/Feb/2016):

    NEW QUESTION 315
    Which services allow the customer to retain run administrative privileges or the undertying EC2 instances? (Choose two.)

    A. AWS Elastic Beanstalk
    B. Amazon Elastic Map Reduce
    C. Elastic Load Balancing
    D. Amazon Relational Database Service
    E. Amazon Elasti Cache

    Answer: AB

    NEW QUESTION 316
    When an EC2 instance mat is backed by an S3-Dased AMI is terminated, what happens to the data on the root volume?

    A. Data is automatically deleted
    B. Data is automatically saved as an EBS snapshot
    C. Data is unavailable until the instance is restarted
    D. Data is automatically saved as an EBS volume

    Answer: A

    NEW QUESTION 317
    How can you secure data at rest on an EBS volume?

    A. Encrypt the volume using the S3 server-side encryption service.
    B. Attach the volume to an instance using EC2’s SSL interface.
    C. Create an IAM policy that restricts read and write access to the volume.
    D. Write the data randomly instead of sequentially.
    E. Use an encrypted file system m top of the EBS volume.

    Answer: C

    NEW QUESTION 318
    In order to optimize performance for a compute cluster that requires low inter-node latency, which feature in the following list should you use?

    A. AWS Direct Connect
    B. Placement Groups
    C. VPC private subnets
    D. EC2 Dedicated Instances
    E. Multiple Availability Zones

    Answer: B
    Explanation:
    A placement group is a logical grouping of instances within a single Availability Zone. Using placement groups enables applications to participate in a low-latency, 10 Gigabits per second (Gbps) network. Placement groups are recommended for applications that benefit from low network latency, high network throughput, or both. To provide the lowest latency, and the highest packet-per-second network performance for your placement group, choose an instance type that supports enhanced networking.

    NEW QUESTION 319
    Amazon EBS snapshots have which of the following two characteristics? (Choose two.)

    A. EBS snapshots only save incremental changes from snapshot to snapshot
    B. EBS snapshots can be created in real-time without stopping an EC2 instance
    C. EBS snapshots can only be restored to an EBS volume of the same size or smaller
    D. EBS snapshots can only be restored and mounted to an instance in the same Availability Zone as the original EBS volume

    Answer: AB

    NEW QUESTION 320
    You have a proprietary data store on-premises that must be backed up daily by dumping the data store contents to a single compressed 50GB file and sending the file to AWS. Your SLAs state that any dump file backed up within the past 7 days can be retrieved within 2 hours. Your compliance department has stated that all data must be held indefinitely. The time required to restore the data store from a backup is approximately 1 hour. Your on-premise network connection is capable of sustaining 1gbps to AWS. Which backup methods to AWS would be most cost-effective while still meeting all of your requirements?

    A. Send the daily backup files to Glacier immediately after being generated
    B. Transfer the daily backup files to an EBS volume in AWS and take daily snapshots of the volume
    C. Transfer the daily backup files to S3 and use appropriate bucket lifecycle policies to send to Glacier
    D. Host the backup files on a Storage Gateway with Gateway-Cached Volumes and take daily snapshots

    Answer: C
    Explanation:
    Because in the stored volume mode, you are storing data locally, the binary-compressed format is already available, and the bandwidth of your AWS connection meets the 7days/2hour SLA.

    This is a sure question. I managed to pass with 92% and recollected most of the questions appeared in my test. Not sure if they ask the same questions or shuffle from a set of questions. You may get the questions from various sites, but the challenge is to find the correct answer.

    As per AWS Certification FAQ (https://aws.amazon.com/certification/faqs/), “AWS Certification passing scores are set by using statistical analysis and are subject to change. AWS does not publish exam passing scores because exam questions and passing scores are subject to change without notice”. Some websites forums say it is 65%.

    Total 55 questions from 7 categories (http://awstrainingandcertification.s3.amazonaws.com/production/AWS_certified_sysops_associate_blueprint.pdf). You will get category wise result. This will help you to narrow down the questions which you lost. I guess I lost 4 (Two in analysis one each from security and Deployment). Somehow I have identified the lost questions and found the correct answer (just for my satisfaction 😉 )
