Question 79 (Topic 1)

A company wants to use NAT gateways in its AWS environment. The company's Amazon EC2 instances in private subnets must be able to connect to the public internet through the NAT gateways. Which solution will meet these requirements?

Select an option, then click Submit answer.

○ Create public NAT gateways in the same private subnets as the EC2 instances.
○ Create private NAT gateways in the same private subnets as the EC2 instances.
○ Create public NAT gateways in public subnets in the same VPCs as the EC2 instances.
○ Create private NAT gateways in public subnets in the same VPCs as the EC2 instances.

Reference / correct answer:

Create public NAT gateways in public subnets in the same VPCs as the EC2 instances.

Most accepted answer: C. Create public NAT gateways in public subnets in the same VPCs as the EC2 instances.

Community votes: C=4

Selected Answer: C Should be C: Public NAT GW in Public Subnet to have access to internet. Private NAT GW is used for VPC or on-prem upvoted 16 times

Selected Answer: C I think the correct is C, because D would require more than just private NAT gateway. Private – Instances in private subnets can connect to other VPCs or your on-premises network through a private NAT gateway. You can route traffic from the NAT gateway through a transit gateway or a virtual private gateway. You cannot associate an elastic IP address with a private NAT gateway. You can attach an internet gateway to a VPC with a private NAT gateway, but if you route traffic from the private NAT gateway to the internet gateway, the internet gateway drops the traffic. https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat-gateway.html upvoted 9 times

Question 80 (Topic 1)

A company runs a highly available web application on Amazon EC2 instances behind an Application Load Balancer. The company uses Amazon CloudWatch metrics. As the traffic to the web application increases, some EC2 instances become overloaded with many outstanding requests. The CloudWatch metrics show that the number of requests processed and the time to receive the responses from some EC2 instances are both higher compared to other EC2 instances. The company does not want new requests to be forwarded to the EC2 instances that are already overloaded. Which solution will meet these requirements?

Select an option, then click Submit answer.

○ Use the round robin routing algorithm based on the RequestCountPerTarget and ActiveConnectionCount CloudWatch metrics.
○ Use the least outstanding requests algorithm based on the RequestCountPerTarget and ActiveConnectionCount CloudWatch metrics.
○ Use the round robin routing algorithm based on the RequestCount and TargetResponseTime CloudWatch metrics.
○ Use the least outstanding requests algorithm based on the RequestCount and TargetResponseTime CloudWatch metrics.

Reference / correct answer:

Use the least outstanding requests algorithm based on the RequestCountPerTarget and ActiveConnectionCount CloudWatch metrics.

Most accepted answer: B. Use the least outstanding requests algorithm based on the RequestCountPerTarget and ActiveConnectionCount CloudWatch metrics.

Community votes: B=7, D=4

Selected Answer: B Option B is correct because can use "RequestCountPerTarget" to identify the amount of requests for each EC2 instance. Then use "least outstanding requests algorithm" to route to targets with the lowest number of in progress requests. Option D is wrong because "RequestCount" cannot identify the amount of requests for each EC2 instance. "RequestCount" is for the whole ALB. upvoted 11 times Tatai2015 2 years, 2 months ago https://aws.amazon.com/about-aws/whats-new/2019/11/application-load-balancer-now-supports-least-outstanding-requests-algorithm-for-load-balancing-requests/ upvoted 3 times ...

Option B would be the correct choice upvoted 8 times

Selected Answer: D D is correct. https://docs.aws.amazon.com/elasticloadbalancing/latest/application/load-balancer-cloudwatch-metrics.html ActiveConnectionCount - The total number of concurrent TCP connections active from clients to the load balancer RequestCountPerTarget - The average request count per target, in a target group Both metrics do not show stage of every target. RequestCount - The number of requests processed over IPv4 and IPv6. This metric is only incremented for requests where the load balancer node was able to choose a target. We can say how many requests go to targets. TargetResponseTime - The time elapsed, in seconds, after the request leaves the load balancer until the target starts to send the response headers. We have metric to get statistics for every target/instance. In fact Item D is correct upvoted 1 times

Selected Answer: B Actually ,I now vote for B and not D upvoted 1 times

Question 81 (Topic 1)

A company has a new mobile app. Anywhere in the world, users can see local news on topics they choose. Users also can post photos and videos from inside the app. Users access content often in the first minutes after the content is posted. New content quickly replaces older content, and then the older content disappears. The local nature of the news means that users consume 90% of the content within the AWS Region where it is uploaded. Which solution will optimize the user experience by providing the LOWEST latency for content uploads?

Select an option, then click Submit answer.

○ Upload and store content in Amazon S3. Use Amazon CloudFront for the uploads.
○ Upload and store content in Amazon S3. Use S3 Transfer Acceleration for the uploads.
○ Upload content to Amazon EC2 instances in the Region that is closest to the user. Copy the data to Amazon S3.
○ Upload and store content in Amazon S3 in the Region that is closest to the user. Use multiple distributions of Amazon CloudFront.
