An IT Consulting company has three separate AWS accounts in different regions with one VPC on each account. The manager instructed you to connect the three VPCs to each other and reminded you that these VPCs have no overlapping IPv4 or IPv6 CIDR blocks.
Which of the following is the most cost-effective connectivity option for this scenario?
Use a VPN connection to connect all 3 VPCs.
Set up a NAT gateway on each VPC to connect to the other VPCs.
Set up a VPC peering connection between the 3 VPCs.
Set up an AWS Direct Connect connection for all three VPCs.
A popular sports website, which provides news, opinions, and videos on various sports events around the world, is hosted in AWS. The website’s architecture has an Auto Scaling group of On-Demand EC2 instances across multiple Availability Zones with an Application Load Balancer (ALB) to evenly distribute the incoming traffic. Lately, online readers have been giving the site a low rating because of the slow loading time of their site. Due to the upcoming FIFA World cup competition, it is expected that the traffic will continue to surge in the coming weeks ahead.
Which of the following services can be used as a cost-effective solution to scale and improve the site’s loading time?
Set up VPC peering
Enable Enhanced Networking
Set up a Network Load Balancer instead of an ALB
Set up a CloudFront distribution
An organization recently deployed a web application in an Amazon VPC with subnets in three Availability Zones. The engineering team decided to launch three EC2 instances from an Auto Scaling Group (ASG) behind an Application Load Balancer (ALB). One of the engineers noticed that two of the instances are deployed in the same AZ and are not distributed evenly across the three availability zones. He confirmed that there are no errors in the ASG’s activity history.
What do you think is the MOST likely reason behind this unexpected placement of instances?
The Auto Scaling group was configured to deploy instances on two Availability Zones only.
The Amazon EC2 Auto Scaling feature is randomly distributing instances on the Availability Zones.
The load balancer was configured to support two Availability Zones only.
The Target Group has Least Outstanding as Routing Algorithm enabled
A SysOps Administrator is managing a web application hosted in an Amazon EC2 instance. The security groups and network ACLs are configured to allow HTTP and HTTPS traffic in your instance. A manager has received a report that a customer cannot access the application. The Administrator is instructed to investigate if the traffic is reaching the instance.
Which of the following is the best approach to satisfy this requirement?
Use Amazon CloudWatch Logs
Use AWS ELB Access Logs
Use AWS CloudTrail Logs
Use Amazon VPC Flow Logs
A SysOps Administrator needs to set up a PostgreSQL database server that runs on a Reserved EC2 instance which will be used by various internal applications within a VPC. To simplify the naming convention of the database server, the Administrator is planning to allocate a custom domain name for the database.
Which of the following should the Administrator do to complete this task?
Set up a publicly hosted zone in Route 53. Create an A or AAAA record, such as db.jumpingbrains.com, and specify the IP address of the database server.
Set up a private hosted zone in Route 53. Create an A or AAAA record, such as db.jumpingbrains.com, and specify the IP address of the database server.
Set up a publicly hosted zone in Route 53. Create a CNAME record, such as db.jumpingbrains.com, and specify the IP address of the database server.
Set up a private hosted zone in Route 53. Create a CNAME record, such as db.jumpingbrains.com, and specify the IP address of the database server.
A media organization recently adopted a hybrid cloud architecture to save costs and to integrate various AWS services. They have a public website which is deployed in two AWS regions: US East (Ohio) and Asia Pacific (Tokyo), to improve their services in Asia.
As a SysOps Administrator, which of the following should you implement to ensure that users are consistently directed to the AWS region nearest to them?
Set up a Route 53 Geoproximity routing policy to direct users in Asia to their website.
Use a third-party geolocation service and redirect the users to the nearest AWS Region based on their country.
Set up the Application Load Balancer of the website to route the incoming traffic to the nearest AWS Region based on its country.
Set up to a Route 53 Latency-based routing for the website.
