3: You are consulting for a finance company that has specific backup and archiving policies. This company's RTO for all financial documents created in the past 6 months is 1 hour. The second requirement is to configure a setup that allows for all documents that are 6 months or older to be sent automatically for archiving in a lower-cost but highly durable archive environment. Given that the company is using the storage gateway, gateway-stored configuration, which of the following would be the best setup to reach the objectives?
4: Your company is concerned with EBS volume backup on Amazon EC2 and wants to ensure they have proper backups and that the data is durable. What solution would you implement and why?
5: You are working for a startup company that is building an application that receives large amounts of data. Unfortunately, current funding has left the start-up short on cash, cannot afford to purchase thousands of dollars of storage hardware, and has opted to use AWS. Which services would you implement in order to store a virtually unlimited amount of data without any effort to scale when demand unexpectedly increases?
S3
7: Which of the following relational database servers are NOT available on Amazon RDS?
DB2
9: True or False: Data stored on EBS volumes are automatically and redundantly stored in multiple physical volumes in the same availability zone as part of the normal operations of the EBS service at no additional charge.
True
11: You've been tasked with building out a duplicate environment in another region for disaster recovery purposes. Part of your environment relies on EC2 instances with preconfigured software. What steps would you take to configure the instances in another region?
Create AMI of instance and copy to the region
13: You are a consultant tasked with migrating an on-premise application architecture to AWS. During your design process you have to give consideration to current on-premise security and determine which security attributes you are responsible for on AWS. Which of the following does AWS provide for you as part of the shared responsibility model?
Physical Network Infrastructure
15: You're building out an application on AWS that is running within a single region. However, you're designing with disaster recovery in mind. Your intention is to build the application so that if the current region becomes unavailable, you can failover to another region. Part of your application relies heavily on pre-built AMIs. In order to share those AMIs with the region you're using as a backup, what process would you take?
17: After building an application that makes use of an Elastic Load Balancer over port 80, you notice that your instances, even though they are healthy as part of the health check, are not serving traffic when you go to the ELB DNS cname. What might be the cause of this issue?
18: If an instance that belongs to an Elastic Load Balancer's health check fails, what occurs to the instance that fails?
ELB will deregister an not send the traffic
20: Amazon Glacier is designed for:
Data archives
21: In the basic monitoring package for EC2, Amazon CloudWatch provides the following metrics:
CPU Utilization
24: Company B provides an online image recognition service and utilizes SQS to decouple system components for scaleability. The SQS consumer's readers poll the image queue as often as possible to keep end-to-end throughput as high as possible. However, Company B is realizing that polling in tight loops is burning CPU cycles and increasing costs with empty responses. How can company B reduce the number of empty responses?
Enable long polling
26: True or False: Amazon SQS (Simple Queue Service) guarantees the delivery of a message AT LEAST once, but cannot guarantee it will not create duplicates.
True
28: While implementing a disaster recovery strategy in another region, you are attempting to move the data from one EBS volume to another in a separate region. What is the best way to do this? Keep in mind this is not a live production replication copy.
Take snapshot and copy to region
30: One of your instances is reporting an unhealthy system status check. However, this is not something you should have to monitor and repair on your own. How might you automate the repair of the system status check failure in an AWS environment?
Use cloudwatch
32: An AWS VPC (Virtual Private Cloud) allows you to _______.
34: What URL might you query on an EC2 instance to find the public AND private IP address of an instance?
36: Your company has an application that requires access to a NoSQL database. Your IT department has no desire to manage the NoSQL servers. Which Amazon service provides a fully-managed and highly available NoSQL service?
DynamoDB
38: True of False: Amazon Auto Scaling is not meant to handle instant load spikes but is built to grow with a gradual increase in usage over a short time period.
true
40: You own an image manipulation application. Your users take a picture, upload it to your app, and request filters to be added to the image. You need to decouple the application so your users are not waiting for the image processing to take place. How would you go about doing this?
SQS
42: As part of your application architecture requirements, the company you are working for has requested the ability to run analytics against all combined log files from the Elastic Load Balancer. Which services are used together to collect logs and process log file analysis in an AWS environment?
EC2 and EMR
44: Your company requires that all the data on your EBS-backed EC2 volumes be encrypted. How would you go about doing this?
Enable it
46: Your company is moving their entire 20 TB data warehouse to the cloud. With your current bandwidth it would take 2 months to transfer the data. Which service would allow you to quickly get your data into AWS?
Amazon Import Export
48: When a snapshot is being taken against an EBS volume, the volume becomes unavailable and the instance no longer has the ability to communicate with the EBS volume until the snapshot is complete.
False
50: You are planning on creating an EC2 instance that will create S3 objects and modify CloudWatch alarms. What is the best way to deploy this instance?
52: You recently purchased four reserved EC2 instances in the US-East-1 region’s Availability Zone 1. Your supervisor just informed you that she would like the instances distributed equally across US-East-1 region Availability Zones 1 and 2. Can you use the reserved instances you just purchased to deploy EC2 instances in Availability Zone 2?
54: Which of the following is not a legitimate concern?
56: Your supervisor asks you to create a highly available, decoupled web application. Which of the following does not help you accomplish this goal?
Elastic Load Balancers, Auto Scaling, and SQS can all play a part in a highly available, decoupled web application. IAM user credentials should not be stored on a EC2 instance.
58: Your supervisor calls you wanting to know why an SWF workflow you created has not made any progress in the last three weeks. What is the most likely explanation for the workflow’s behavior?
SWF task and workflow execution can last up to one year, and can include tasks to be performed by on-premises servers and humans.
60: You are using IOT sensors to monitor the movement of a group of hikers on a three day trek and send the information into an Kinesis Stream. They each have a sensor in their shoe and you know for certain that there is no problem with mobile coverage so all the data is getting back to the stream. You have used default settings for the stream. At the end of the third day the data is sent to an S3 bucket. When you go to interpret the data in S3 there is only data for the last day and nothing for the first 2 days. Which of the following is the most probable cause of this?
