    1. The public subnet
    2. The private subnet
    3. Either of them
    4. Not recommended, they should ideally be launched outside VPC
  3. An instance is connected to an ENI (Elastic Network Interface) in one subnet. What happens when you attach an ENI of a different subnet to this instance?
    1. The instance follows the rules of the older subnet
    2. The instance follows the rules of both the subnets
    3. The instance follows the rules of the newer subnet
    4. Not possible cannot be connected to 2 ENIs

    1. A.
    2. AAAA
    3. NS
    4. CNAME

    1. 1/7th of the  time
    2. 3/10th of the time
    3. 3/7th of the time
    4. 1/4th of the time
  6. You have created a Route 53 latency record set from your domain to a machine in Singapore and a similar record to a machine in Oregon. When a user located in India visits your domain he will be routed to:
    1. Singapore
    2. Oregon
    3. Depends on the load on each machine
    4. Both, because 2 requests are made, 1 to each machine
  7. Which of the following can be used as an origin server in CloudFront?(Choose 3)
    1. A webserver running on EC2
    2. A webserver running in your own datacenter
    3. A RDS instance
    4. An Amazon S3 bucket
  8. In CloudFront what happens when content is NOT present at an Edge location and a request is made to it?
    1. An Error 404 not found is returned
    2. CloudFront delivers the content directly from the origin server and stores it in the cache of the edge location
    3. The request is kept on hold till content is delivered to the edge location
    4. The request is routed to the next closest edge location
  9. Which of the following is true with respect to serving private content through CloudFront?
    1. Signed URLs can be created to access objects from CloudFront edge locations
    2. Direct access to S3 URLs can be removed therefore allowing access only through CloudFront URLs
    3. Mark the S3 bucket private and allow access to CloudFront by means of Roles
    4. Mark the S3 bucket private and and create an Origin Access Identity to access the objects
  10. You have written a CloudFormation template that creates 1 elastic load balancer fronting 2 EC2 instances. Which section of the template should you edit so that the DNS of the load balancer is returned upon creation of the stack.
    1. Resources
    2. Parameters
    3. Outputs

    Answer for Q3 is b..reason is for weighted routing policies, 1,2,3 &4, first it will sum up all which is going to be 10 and then distribute by the given weights. So it is going to be like this 1/10,2/10,3/10 and 4/10..So for 3rd record set the traffic is 3/10

    I think the answer for question-1 is not correct, the ec2 instance lauched in public vpc can be accessible via default public IP assign to that instance.

    Answer to 1 is wrong. you need to put elastic ip only if it is launched into a non default VPC. Your default VPC comes with an Internet gateway, and instances launched into a default subnet receive a public IP address by default, unless you specify otherwise during launch, or you modify the subnet’s public IP address attribute. Therefore, instances that you launch into a default subnet can automatically communicate with the Internet… https://docs.aws.amazon.com/AmazonVPC/latest/UserGuide/VPC_Internet_Gateway.html

      Hey Rajesh. Unless the questions says “Default VP” you cannot assume Default VPC. Thus the answer is correct. You are correct if the question said “Default VPC”, then we will not need to attach public IP manually. So the answer is correct 🙂

        I vote for Rajesh on this one. By definition, “Default” would be selected if nothing is specified.

    I’m not sure #6 (a) is correct. It’s most likely that a request from India will be serviced by the Singapore server, but if the Singapore server is always busy or there’s some kind of weird routing (eg a corporate connection via the USA) then it’s possible it will be serviced by the USA server.

      I agree with Tim, If your application is hosted on Amazon EC2 instances in multiple Amazon EC2 regions, you can reduce latency for your users by serving their requests from the Amazon EC2 region for which network latency is lowest. Amazon Route 53 latency-based routing lets you use DNS to route user requests to the Amazon EC2 region that will give your users the fastest response.

      With Geolocation routing lets you choose the resources that serve your traffic based on the geographic location of your users, meaning the location from which DNS queries originate.

    Hello,

    Here is the procedure.
    Forward main domain to www. as subdomain
    and point a CNAME to the subdomain ,use aws elb as CNAME here.
    Aws elb ips are not static…:)

    I don’t see why in question 8 answer C is wrong, even though answer B is correct too. The request is kept on hold till content is delivered to the edge location, even though the delivery happens as soon as the first byte arrives from the origin server

    You cannot create a CNAME for the top level of the domain, thus A record with Alias is correct. AWS will update the alias record when the ELB DNS name changes

    Shaan, you cannot use A record for ELB. As ELB might change its IP address. Thus only CNAME is the right answer.

    CNAME and A with alias are both valid answers

    Daniel, I can understand your confusion, here we are trying to route www subdomain, so Alias will not be useful, we should create CNAME.

    The answer of question 4 was wrong.
    The correct is “A”, and set the option “Alias” to “Yes”.
