Questions # 31:

A network engineer needs to provide a list of IP addresses that are sending traffic to an Amazon EC2 instance. VPC flow logs are enabled. The EC2 instance has a single network interface and two assigned IP addresses. However, the flow logs are logging traffic only for the primary IP address. The network engineer needs to determine whether any traffic is being sent to the second IP address of the EC2 instance.

What should the network engineer do to locate the traffic flow for the second IP address?

Options:

A.

Create a new flow log that includes the pkt-dstaddr field to capture the original destination IP address of the traffic.


B.

Create a new flow log that includes the dstaddr field to capture the original destination IP address of the traffic.


C.

Create a new flow log that includes the pkt-srcaddr field to capture the originaldestination IP address of the traffic.


D.

Create a new flow log that includes the srcaddr field to capture the original destination IP address of the traffic.

Questions # 32:

A company runs workloads in multiple VPCs in the us-east-1 Region. The VPCs are connected to a transit gateway. An AWS Direct Connect connection provides private connectivity between a data center that is in the US and the transit gateway. A Direct Connect gateway is associated with the transit gateway.

The company has recently opened a new office location in London. The company plans to launch cloud services in multiple VPCs in the eu-west-2 Region. Users in the new London office must have private access to the workloads that run in us-east-1. Users in the US data center must have access to any workloads that are created in eu-west-2. A network engineer must implement a flexible solution that provides users the required access. The solution must be able to accommodate future growth.

Questions # 33:

A company has two AWS Direct Connect connections between Direct Connect locations and the company's on-premises environment in the US. The company uses the connections to communicate with AWS workloads that run in the us-east-1 Region. Thecompany has a transit gateway that connects several VPCs. The Direct Connect connections terminate at a Direct Connect gateway and the transit VIFs to the transit gateway.

The company recently acquired a smaller company that is based in Europe. The newly acquired company has only on-premises workloads. The newly acquired company does not

expect to run workloads on AWS for the next 3 years. However, the newly acquired company requires connectivity to the parent company's AWS resources in us-east-1 and to the

parent company's on-premises environment in the US. The parent company wants to use two new Direct Connect connections in Europe to provide the required connectivity.

Which solution will meet these requirements with the LEAST operational overhead for the newly acquired company?

Options:

A.

Associate new transit VIFs to the existing Direct Connect gateway. Configure the new transit VIFs to use Direct Connect SiteLink.

Questions # 34:

A company is using Amazon Route 53 Resolver DNS Firewall in a VPC to block all domains except domains that are on an approved list. The company is concerned that if DNS Firewall is unresponsive, resources in the VPC might be affected if the network cannot resolve any DNS queries.

Which change should a network engineer implement to meet these requirements?

Options:

A.

Update the DNS Firewall VPC configuration to disable fail open for the VPC.


B.

Update the DNS Firewall VPC configuration to enable fail open for the VPC.


C.

Create a new DHCP options set with parameter dns_firewall_fail_open=false. Associate the new DHCP options set with the VPC.


D.

Create a new DHCP options set with parameter dns_firewall_fail_open=true. Associate the new DHCP options set with the VPC.

Questions # 35:

A company’s network engineer builds and tests network designs for VPCs in a development account. The company needs to monitor the changes that are made to network resources and must ensure strict compliance with network security policies. The company also needs access to the historical configurations of network resources.

Which solution will meet these requirements?

Options:

A.

Create an Amazon EventBridge (Amazon CloudWatch Events) rule with a custom pattern to monitor the account for changes. Configure the rule to invoke an AWS Lambda function to identify noncompliant resources. Update an Amazon DynamoDB table with the changes that are identified.


B.

Create custom metrics from Amazon CloudWatch logs. Use the metrics to invoke an AWS Lambda function to identify noncompliant resources. Update an Amazon DynamoDB table with the changes that are identified.


C.

Record the current state of network resources by using AWS Config. Create rules that reflect the desired configuration settings. Set remediation for noncompliant resources.


D.

Record the current state of network resources by using AWS Systems Manager Inventory. Use Systems Manager State Manager to enforce the desired configuration settings and to carry out remediation for noncompliant resources.

Questions # 36:

A company has a hybrid environment that connects an on-premises data center to the AWS Cloud. The hybrid environment uses a 10 Gbps AWS Direct Connect dedicated connection. The Direct Connect connection has multiple private VIFs that terminate in multiple VPCs.

To comply with regulations, the company must encrypt all WAN traffic, regardless of the underlying transport. The company needs to implement an encryption solution that will not affect the company's bandwidth capacity.

Which solution will meet these requirements?

Options:

A.

Create a public VIF. Configure a new AWS Site-to-Site VPN connection to use the new public VIF.

Questions # 40:

A security team is performing an audit of a company's AWS deployment. The security team is concerned that two applications might be accessing resources that should be blocked by network ACLs and security groups. The applications are deployed across two Amazon Elastic Kubernetes Service (Amazon EKS) clusters that use the Amazon VPC Container Network Interface (CNI) plugin for Kubernetes. The clusters are in separate subnets within the same VPC and have a Cluster Autoscaler configured.
