Question # 61

A company runs an application on Amazon EC2 instances. A network engineer implements a NAT gateway in the application's VPC to replace self-managed NAT instances. After the network engineer shifts traffic from the self-managed NAT instances to the NAT gateway, users begin to report issues.

During troubleshooting, the network engineer discovers that the connection to the application is closing after approximately 6 minutes of inactivity.

What should the network engineer do to resolve this issue?

Check for increases in the Amazon CloudWatch IdleTimeoutCount metric for the NAT gateway. Configure TCP keepalive on the application EC2 instances.

Check for increases in the Amazon CloudWatch ErrorPortAIlocation metric for the NAT gateway. Configure an HTTP timeout value on the application EC2 instances.

Check for increases in the Amazon CloudWatch PacketsDropCount metric for the NAT gateway. Configure an HTTPS timeout value on the application EC2 instances.

Check for decreases in the Amazon CloudWatch ActiveConnectionCount metric for the NAT gateway. Configure UDP keepalive on the application EC2 instances.

Question # 62

You deploy an Amazon EC2 instance that runs a web server into a subnet in a VPC. An Internet gateway is attached, and the main route table has a default route (0.0.0.0/0) configured with a target of the Internet gateway.

The instance has a security group configured to allow as follows:

Protocol: TCP

Port: 80 inbound, nothing outbound

The Network ACL for the subnet is configured to allow as follows:

Protocol: TCP

Port: 80 inbound, nothing outbound

When you try to browse to the web server, you receive no response.

Which additional step should you take to receive a successful response?

Add an entry to the security group outbound rules for Protocol: TCP, Port Range: 80

Add an entry to the security group outbound rules for Protocol: TCP, Port Range: 1024-65535

Add an entry to the Network ACL outbound rules for Protocol: TCP, Port Range: 80

Question # 64

A company uses Amazon Route 53 to register a public domain, example.com, in an AWS account. A central services group manages the account. The company wants to create a subdomain, test.example.com, in another AWS account to offer name services for Amazon EC2 instances that are hosted in the account. The company does not want to migrate the parent domain to the subdomain account.

A network engineer creates a new Route 53 hosted zone for the subdomain in the second account.

Which combination of steps must the network engineer take to complete the task? (Choose two.)

Add records for the hosts of the new subdomain to the new Route 53 hosted zone.

Update the DNS service for the parent domain by adding name server (NS) records for the subdomain.

Update the DNS service for the subdomain by adding name server (NS) records for the parent domain.

Create an alias record from the parent domain that points to the hosted zone for the subdomain in the second account.

Add a start of authority (SOA) record in the parent domain for the subdomain.

Question # 65

A company needs to protect against potential botnet command and control traffic from any Amazon EC2 instances that is in in the company’s AWS Environment.

Which solution will meet these requirements?

Use AWS Shield Advanced. Activate Shield Advanced protections on the EC2 instances to filter and block botnet traffic.

Use Amazon Route 53 Resolver DNS Firewall. Add a rule to a rule group to use the AWSManagedDomainsBotnetCommandandControl managed domain list with an action to block botnet traffic.

Use AWS WAF Bot Control. Configure a managed rule group that uses an AWS managed rule set to block botnet traffic.

Use AWS Systems Manager. Run a Systems Manager Automation runbook on the EC2 instances to configure the instances to block botnet traffic.

Question # 66

A company uses a hybrid architecture and has an AWS Direct Connect connection between its on-premises data center and AWS. The company has production applications that run in the on-premises data center. The company also has production applications that run in a VPC. The applications that run in the on-premises data center need to communicate with the applications that run in the VPC. The company is using corp.example.com as the domain name for the on-premises resources and is using an Amazon Route 53 private hosted zone for aws.example.com to host the VPC resources.

The company is using an open-source recursive DNS resolver in a VPC subnet and is using a DNS resolver in the on-premises data center. The company's on-premises DNS resolver has a forwarder that directs requests for the aws.example.com domain name to the DNS resolver in the VPC. The DNS resolver in the VPC has a forwarder that directs requests for the corp.example.com domain name to the DNS resolver in the on-premises data center. The company has deckled to replace the open-source recursive DNS resolver with Amazon Route 53 Resolver endpoints.

Which combination of steps should a network engineer take to make this replacement? (Choose three.)

Create a Route 53 Resolver rule to forward aws.example.com domain queries to the IP addresses of the outbound endpoint.

Configure the on-premises DNS resolver to forward aws.example.com domain queries to the IP addresses of the inbound endpoint.

Create a Route 53 Resolver inbound endpoint and a Route 53 Resolver outbound endpoint.

Create a Route 53 Resolver rule to forward aws.example.com domain queries to the IP addresses of the inbound endpoint.

Create a Route 53 Resolver rule to forward corp.example.com domain queries to the IP address of the on-premises DNS resolver.

Configure the on-premises DNS resolver to forward aws.example.com queries to the IP addresses of the outbound endpoint.

Question # 67

A company has hundreds of VPCs on AWS. All the VPCs access the public endpoints of Amazon S3 and AWS Systems Manager through NAT gateways. All the traffic from the VPCs to Amazon S3 and Systems Manager travels through the NAT gateways. The company's network engineer must centralize access to these services and must eliminate the need to use public endpoints.

Which solution will meet these requirements with the LEAST operational overhead?

Create a central egress VPC that has private NAT gateways. Connect all the VPCs to the central egress VPC by using AWS Transit Gateway. Use the private NAT gateways to connect to Amazon S3 and Systems Manager by using private IP addresses.

Set the dead peer detection (DPD) timeout action to Clear. Initiate traffic from the VPC to on premises.

Set the dead peer detection (DPD) timeout action to Restart. Initiate traffic from on premises to the VPC.

Set the dead peer detection (DPD) timeout action to None. Initiate traffic from the VPC to on premises.

Set the dead peer detection (DPD) timeout action to Cancel. Initiate traffic from on premises to the VPC.

Question # 69

A logistics company has multiple VPCs in an AWS Region. The company uses a transit gateway to connect the VPCs. The company has several on-premises offices that connect to the transit gateway by using AWS Site-to-Site VPN connections over the internet. The company has configured one transit gateway VPN attachment for each office.

Route propagation is enabled on all route tables. Each Site-to-Site VPN connection uses two tunnels in an active-passive configuration. The company configured each office with appropriate static routes on both the Site-to-Site VPN connection and the office’s customer gateway.

The company wants to use both IPsec tunnels of every office to maximize the overall VPN connection bandwidth.

Which design changes are necessary to meet these requirements?

Create an AWS Transit Gateway Connect attachment for each office Use the existing VPN attachments as the transport for the new Connect attachments. Set up a Generic Routing

Encapsulation (GRE) tunnel on each customer gateway that terminates on the Connect attachment for each office. Move the static routes from the transit gateway VPN attachment to the customer gateway for the transit gateway Connect attachment.
