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
3.
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.
4.
You define the following S3 bucket policy to grant users

using a command line utility from a machine that doesn't
have any AWS credentials setup. What might be the issue?
A. The website requires an IAM role that allows it to access the objects in the bucket.
B. The ACLs are misconfigured and are blocking other websites from making requests to
the objects.
C. The S3 Bucket policy is blocking other websites from making requests to the bucket.

You have created an Elastic Load Balancer with Duration-
Based sticky sessions enabled in front of your six EC2 web
application instances in US-West-2. For High Availability,
there are three web application instances in Availability Zone
1 and three web application instances in Availability Zone 2.
To load test, you set up a software-based load tester in
Availability Zone 2 to send traffic to the Elastic Load Balancer,
as well as letting several hundred users browse to the ELB’s
hostname. After a while, you notice that the users’ sessions
are spread evenly across the EC2 instances in both AZ’s, but
the software-based load tester’s traffic is hitting only the
instances in Availability Zone 2. What steps can you take to
resolve this problem?
A. Switch to Application-Controlled sticky sessions
B. Create a software-based load tester in US-East-1 and test from there
C. Force the software-based load tester to re-resolve DNS before every request
Correct
D. Use a third party load-testing service to send requests from globally
Correct
