1. Your EBS volumes do not seem to be performing as expected and your team leader has requested you look into improving their performance. Which of the following is not a true statement relating to the performance of your EBS volumes?
A. Frequent snapshots provide a higher level of data durability and they will not degrade the performance of your application while the snapshot is in progress.
B. General Purpose (SSD) and Provisioned IOPS (SSD) volumes have a throughput limit of 128 MB/s per volume.
C. There is a relationship between the maximum performance of your EBS volumes, the amount of I/O you are drMng to them, and the amount of time it takes for each transaction to complete.
D. There is a 5 to 50 percent reduction in IOPS when you first access each block of data on a newly created or restored EBS volume
Answer: A
Explanation:
Several factors can affect the performance of Amazon EBS volumes, such as instance configuration,
I/O characteristics, workload demand, and storage configuration.
Frequent snapshots provide a higher level of data durability, but they may slightly degrade the
performance of your application while the snapshot is in progress. This trade off becomes critical when you
have data that changes rapidly. Whenever possible, plan for snapshots to occur during off-peak times in
order to minimize workload impact.
2.You’ve created your first load balancer and have registered your EC2 instances with the load balancer. Elastic Load Balancing routinely performs health checks on all the registered EC2 instances and automatically distributes all incoming requests to the DNS name of your load balancer across your registered, healthy EC2 instances. By default, the load balancer uses the _ protocol for checking the health of your instances.
A. HTTPS
B. HTTP
C. ICMP
D. IPv6
Answer: B
Explanation:
In Elastic Load Balancing a health configuration uses information such as protocol, ping port, ping path (URL), response timeout period, and health check interval to determine the health state of the instances registered with the load balancer.
Currently, HTTP on port 80 is the default health check.
3. A major finance organisation has engaged your company to set up a large data mining application. Using AWS you decide the best service for this is Amazon Elastic MapReduce(EMR) which you know uses Hadoop. Which of the following statements best describes Hadoop?
A. Hadoop is 3rd Party software which can be installed using AMI
B. Hadoop is an open source python web framework
C. Hadoop is an open source Java software framework
D. Hadoop is an open source javascript framework
Answer: C
Explanation:
Amazon EMR uses Apache Hadoop as its distributed data processing engine. Hadoop is an open source, Java software framework that supports data-intensive distributed applications running on large clusters of commodity hardware. Hadoop implements a programming model named “MapReduce,” where the data is dMded into many small fragments of work, each of which may be executed on any node in the cluster.
This framework has been widely used by developers, enterprises and startups and has proven to be a reliable software platform for processing up to petabytes of data on clusters of thousands of commodity machines.
4. In Amazon EC2 Container Service, are other container types supported?
A. Yes, EC2 Container Service supports any container service you need.
B. Yes, EC2 Container Service also supports Microsoft container service.
C. No, Docker is the only container platform supported by EC2 Container Service presently.
D. Yes, EC2 Container Service supports Microsoft container service and Openstack.
Answer: C
Explanation:
In Amazon EC2 Container Service, Docker is the only container platform supported by EC2 Container Service presently.
5. Is a fast, flexible, fully managed push messaging service.
A. Amazon SNS
B. Amazon SES
C. Amazon SQS
D. Amazon FPS
Answer: A
Explanation:
Amazon Simple Notification Service (Amazon SNS) is a fast, filexible, fully managed push messaging service.
