AWS X-Ray was recently implemented inside of a service that

you work on. Several weeks later, after a new marketing push,

that service started seeing a large spike in traffic and you've

been tasked with investigating a few issues that have started

coming up but when you review the X-Ray data you can't find

enough information to draw conclusions so you decide to:

A. Start passing in the X-Amzn-Trace-Id: True HTTP header from your upstream requests

B. Refactor the service to include additional calls to the X-Ray API using an AWS SDK

C. Update the sampling algorithm to increase the sample rate and instrument

X-Ray to collect more pertinent information



Correct

D. Update your application to use the custom API Gateway TRACE method to send in data

Using the AWS console you've written a Lambda function that

uses a few 3rd party libraries to make requests to a given URL

and determine if specific text appears on the page. When you

test the function locally it works. However, when you paste it

into the AWS Lambda Console and save it there you get an

error. What is the most likely cause of this?

A. You need to bundle your 3rd party dependencies in with your function -

they are not included by default.



Correct

B. The function is most likely timing out - the default is 3 seconds and most functions like

this take at least five.

C. You need to provide more memory than the default in order to make use of 3rd party

libraries.

D. You need to enable the configuration settings to make 3rd party libraries accessible

from inside your function.

You define the following S3 bucket policy to grant users

access to your bucket, but the S3 bucket policy editor will not

allow you to submit it. Why is this policy not working?

``` { "Id": "Policy1441839160967", "Version": "2012-10-17",

"Statement": [ { "Sid": "Stmt1441839157568", "Action": [

"s3:ListBucket" ], "Effect": "Allow", "Resource": "arn:aws:s3:::

linuxacademy.testbucket.2 " } ] }
