Question 1hardmultiple choice

A company has a VPC with a public subnet and a private subnet. An Amazon EC2 instance in the private subnet needs to download security patches from the internet, but the instance must not be directly accessible from the internet. The SysOps administrator configured a NAT gateway in the public subnet and added a route in the private subnet's route table pointing 0.0.0.0/0 to the NAT gateway. The instance's security group allows all outbound traffic. However, the instance still cannot reach the internet. What is the most likely missing configuration?

A company has two Amazon VPCs in the same AWS Region with non-overlapping CIDR blocks. The SysOps administrator needs to establish private connectivity between the two VPCs with high throughput and minimal cost. Which solution should the administrator implement?

Question 3hardmultiple choice

Full question →

A company has three VPCs in the same AWS region: VPC A (production), VPC B (development), and VPC C (shared services). The VPCs have overlapping CIDR blocks (e.g., VPC A: 10.0.0.0/16, VPC B: 10.0.0.0/16, VPC C: 10.1.0.0/16). The SysOps administrator needs to enable private IP communication between VPC A and VPC C, and between VPC B and VPC C, but not between VPC A and VPC B. The solution must also support a growing number of VPCs in the future. Which AWS service should be used?

Question 4hardmultiple choice

Full question →

A company has two VPCs in different AWS regions (us-east-1 and eu-west-1) that are peered. Applications in both VPCs need to communicate using private IP addresses. The ping tests are successful, but the latency is significantly higher than expected. Which change is most likely to improve the latency between the VPCs?

Question 5hardmultiple choice

Full question →

A company has multiple VPCs in the same AWS account and Region, each with overlapping CIDR blocks (10.0.0.0/16). The SysOps administrator needs to establish connectivity between all VPCs and the on-premises network via AWS Transit Gateway. Additionally, certain VPCs must be isolated from each other while still reaching on-premises. How should the administrator configure the Transit Gateway to meet these requirements?

Question 7mediummultiple choice

Full question →

A SysOps administrator deploys a web application using AWS Elastic Beanstalk. The administrator wants to deploy a new application version with zero downtime and minimize the risk of failure by launching a completely new set of instances before swapping traffic. Which deployment policy should the administrator choose?

Question 8hardmultiple choice

Full question →

A SysOps administrator is troubleshooting connectivity issues between Amazon EC2 instances in two different VPCs that are connected via a VPC peering connection. The instances can successfully send ICMP (ping) traffic, but TCP connections on port 443 (HTTPS) fail. The security groups of both instances allow all inbound and outbound traffic. What is the most likely cause of the issue?
