Amazon AWS Certified DevOps Engineer - Professional AWS-DevOps-Engineer-Professional Prüfungsfragen mit Lösungen (Q162-Q167):

162. Frage
Company policies require that information about IP traffic going between instances in the production Amazon VPC is captured. The capturing mechanism must always be enabled and the Security team must be notified when any changes in configuration occur.
What should be done to ensure that these requirements are met?

A. Configure a new trail using AWS CloudTrail service. Using the UserData section of an AWS CloudFormation template, install tcpdump on every provisioned Amazon EC2 instance. Connect Amazon Athena to the CloudTrail and write an AWS Lambda function that monitors for a flow log disable event. Once the CloudTrail entry has been spotted, alert the security organization.
B. Create a flow log for the production VPC and assign an Amazon S3 bucket as a destination for delivery.
Using Amazon S3 Event Notification, set up an AWS Lambda function that is triggered when a new log file gets delivered. This Lambda function updates an entry in Amazon DynamoDB, which is periodically checked by scheduling an Amazon CloudWatch Events rule to notify security when logs have not arrived.
C. Create a flow log for the production VPC. Create a new rule using AWS Config that is triggered by configuration changes of resources of type 'EC2:VPC'. As part of configuring the rule, create an AWS Lambda function that looks up flow logs for a given VPC. If the VPC flow logs are not configured, return a 'NON_COMPLIANT' status and notify the security organization.
D. Using the UserData section of an AWS CloudFormation template, install tcpdump on every provisioned Amazon EC2 instance. The output of the tool is sent to Amazon EFS for aggregation and querying. In addition, scheduling an Amazon CloudWatch Events rule calls an AWS Lambda function to check whether tcpdump is up and running and sends an email to the security organization when there is an exception.

Antwort: C

163. Frage
You need the absolute highest possible network performance for a cluster computing application. You
already selected homogeneous instance types supporting 10 gigabit enhanced networking, made sure
that your workload was network bound, and put the instances in a placement group. What is the last
optimization you can make?

A. Use 9001 MTU instead of 1500 for Jumbo Frames, to raise packet body to packet overhead ratios.
B. Segregate the instances into different peered VPCs while keeping them all in a placement group, so
each one has its own Internet Gateway.
C. Turn off SYN/ACK on your TCP stack or begin using UDP for higher throughput.
D. Bake an AMI for the instances and relaunch, so the instances are fresh in the placement group and do
not have noisy neighbors.

Antwort: A

Begründung:
For instances that are collocated inside a placement group, jumbo frames help to achieve the maximum
network throughput possible, and they are recommended in this case. For more information, see
Placement Groups.

164. Frage
A company wants to use Amazon DynamoDB for maintaining metadata on its forums. See the sample data set in the image below.

A DevOps Engineer is required to define the table schema with the partition key, the sort key, the local secondary index, projected attributes, and fetch operations. The schema should support the following example searches using the least provisioned read capacity units to minimize cost.
-Search within ForumName for items where the subject starts with 'a'.
-Search forums within the given LastPostDateTime time frame.
-Return the thread value where LastPostDateTime is within the last three months.
Which schema meets the requirements?

A. Use ForumName as the primary key and Subject as the sort key. Have LSI with Thread as the sort key and the projected attribute LastPostDateTime.
B. Use Subject as the primary key and ForumName as the sort key. Have LSI with LastPostDateTime as the sort key and fetch operations for thread.
C. Use Subject as the primary key and ForumName as the sort key. Have LSI with Thread as the sort key and fetch operations for LastPostDateTime.
D. Use ForumName as the primary key and Subject as the sort key. Have LSI with LastPostDateTime as the sort key and the projected attribute thread.

Antwort: B

165. Frage
A company is deploying a new mobile game on AWS for its customers around the world. The Development team uses AWS Code services and must meet the following requirements:
- Clients need to send/receive real-time playing data from the backend
frequently and with minimal latency
- Game data must meet the data residency requirement
Which strategy can a DevOps Engineer implement to meet their needs?

A. Deploy the backend application to multiple Availability Zones in a single region. Create an Amazon CloudFront distribution to serve the application backend to global customers. Any update to the code repository triggers a two-stage build-and-deployment pipeline. The pipeline deploys the backend application to all Availability Zones.
B. Deploy the backend application to multiple regions. Any update to the code repository triggers a two- stage build and deployment pipeline. A successful deployment in one region invokes an AWS Lambda function to copy the build artifacts to an Amazon S3 bucket in another region. After the artifact is copied, it triggers a deployment pipeline in the new region.
C. Deploy the backend application to multiple regions. Use AWS Direct Connect to serve the application backend to global customers. Any update to the code repository triggers a two-stage build-and- deployment pipeline in the region. After a successful deployment in the region, the pipeline continues to deploy the artifact to another region.
D. Deploy the backend application to multiple regions. Any update to the code repository triggers a two- stage build-and-deployment pipeline in the region. After a successful deployment in the region, the pipeline invokes the pipeline in another region and passes the build artifact location.
The pipeline uses the artifact location and deploys applications in the new region.

Antwort: C

166. Frage
A company is building a solution for storing files containing Personally Identifiable Information (PII) on AWS.
Requirements state:
- All data must be encrypted at rest and in transit.
- Al data must be replicated in at least two locations that are at
least 500 miles apart.
Which solution meets these requirements?

A. Create primary and secondary Amazon S3 buckets in two separate Availability Zones that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS.
Use a bucket policy to enforce Amazon S3 SSE-C on all objects uploaded to the bucket.
Configure cross- region replication between the two buckets.
B. Create primary and secondary Amazon S3 buckets in two separate AWS Regions that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS.
Use a bucket policy to enforce S3-Managed Keys (SSE-S3) on all objects uploaded to the bucket.
Configure cross- region replication between the two buckets.
C. Create primary and secondary Amazon S3 buckets in two separate Availability Zones that are at least 500 miles apart. Use a bucket policy to enforce access to the buckets only through HTTPS.
Use a bucket policy to enforce AWS KMS encryption on all objects uploaded to the bucket.
Configure cross- region replication between the two buckets. Create a KMS Customer Master Key (CMK) in the primary region for encrypting objects.
D. Create primary and secondary Amazon S3 buckets in two separate AWS Regions that are at least 500 miles apart. Use an IAM role to enforce access to the buckets only through HTTPS. Use a bucket policy to enforce Amazon S3-Managed Keys (SSE-S3) on all objects uploaded to the bucket. Configure cross-region replication between the two buckets.

Antwort: B
