Amazon ANS-C00 Certification Practice Questions & Answers

Question 6 of 377

Your organization uses a VPN to connect to your VPC but must upgrade to a 1-G AWS Direct Connect connection for stability and performance. Your telecommunications provider has provisioned the circuit from your data center to an AWS Direct Connect facility and needs information on how to cross-connect
(e.g., which rack/port to connect).
What is the AWS-recommended procedure for providing this information?

A.

Create a support ticket. Provide your AWS account number and telecommunications company's name and where you need the Direct Connect connection to terminate.

B.

Create a new connection through your AWS Management Console and wait for an email from AWS with information.

C.

Ask your telecommunications provider to contact AWS through an AWS Partner Channel. Provide your AWS account number.

D.

Contact an AWS Account Manager and provide your AWS account number, telecommunications company's name, and where you need the Direct Connect connection to terminate.

Question 7 of 377

You manage a web service that is used by client applications deployed in 300 offices worldwide. The web service architecture is an Elastic Load Balancer (ELB) distributing traffic across four application servers deployed in an Auto Scaling group across two Availability Zones.
The ELB is configured to use round robin, and sticky sessions are disabled. You have configured the NACLs and security groups to allow port 22 from your bastion host, and port 80 from 0.0.0.0/0. The client configuration is managed by each regional IT team.
Upon inspection you find that a large amount of requests from incorrectly configured sites are causing a single application server to degrade. The remainder of the requests are equally distributed across all servers with no negative effects.
What should you do to remedy the situation and prevent future occurrences?

A.

Mark the affected instance as degraded in the ELB and raise it with the client application team.

B.

Update the NACL to only allow port 80 to the application servers from the ELB servers.

C.

Update the Security Groups to only allow port 80 to the application servers from the ELB.

D.

Terminate the affected instance and allow Auto Scaling to create a new instance.

Question 8 of 377

A multinational organization has applications deployed in three different AWS regions. These applications must securely communicate with each other by VPN.
According to the organization's security team, the VPN must meet the following requirements:
✑ AES 128-bit encryption
✑ SHA-1 hashing
✑ User access via SSL VPN
✑ PFS using DH Group 2
✑ Ability to maintain/rotate keys and passwords
✑ Certificate-based authentication
Which solution should you recommend so that the organization meets the requirements?

A.

AWS hardware VPN between the virtual private gateway and customer gateway

B.

A third-party VPN solution deployed from AWS Marketplace

C.

A private MPLS solution from an international carrier

D.

AWS hardware VPN between the virtual private gateways in each region

Question 9 of 377

Refer to the image.
Exam ANS-C00: Question 9 - Image 1

You have three VPCs: A, B, and C. VPCs A and C are both peered with VPC B. The IP address ranges are as follows:
✑ VPC A: 10.0.0.0/16
✑ VPC B: 192.168.0.0/16
✑ VPC C: 10.0.0.0/16
Instance i-1 in VPC A has the IP address 10.0.0.10. Instance i-2 in VPC C has the IP address 10.0.0.10. Instances i-3 and i-4 in VPC B have the IP addresses
192.168.1.10 and 192.168.1.20, respectively, i-3 and i-4 are in the subnet 192.168.1.0/24.
✑ i-3 must be able to communicate with i-1
✑ i-4 must be able to communicate with i-2
✑ i-3 and i-4 are able to communicate with i-1, but not with i-2.
Which two steps will fix this problem? (Choose two.)

A.

Create subnets 192.168.1.0/28 and 192.168.1.16/28. Move i-3 and i-4 to these subnets, respectively.

B.

Create subnets 192.168.1.0/27 and 192.168.1.16/27. Move i-3 and i-4 to these subnets, respectively.

C.

Change the IP address of i-2 to 10.0.0.100. Assign it an elastic IP address.

D.

Create a new route table for VPC B, with unique route entries for destination VPC A and destination VPC C.

E.

Create two route tables: one with a route for destination VPC A, and another for destination VPC C.

Question 10 of 377

A legacy, on-premises web application cannot be load balanced effectively. There are both planned and unplanned events that cause usage spikes to millions of concurrent users. The existing infrastructure cannot handle the usage spikes. The CIO has mandated that the application be moved to the cloud to avoid further disruptions, with the additional requirement that source IP addresses be unaltered to support network traffic-monitoring needs. Which of the following designs will meet these requirements?

A.

Use an Auto Scaling group of Amazon EC2 instances behind a Classic Load Balancer.

B.

Use an Auto Scaling group of EC2 instances in a target group behind an Application Load Balancer.

C.

Use an Auto Scaling group of EC2 instances in a target group behind a Classic Load Balancer.

D.

Use an Auto Scaling group of EC2 instances in a target group behind a Network Load Balancer.
