Question 1
- A company wants to analyze TCP internet traffic. The traffic originates from Amazon EC2 instances in the companys VPC. The EC2 instances initiate connections through a NAT gateway. The company wants to capture data about the traffic including source and destination IP addresses ports, and the first 8 bytes of the TCP segments of the traffic. The company needs to collect, store, and analyze all the required data points. Which solution will meet these requirements?
  A : Configure the EC2 instances to be VPC traffic mirror sources. Deploy software on the traffic mirror target to forward the data to Amazon CloudWatch Logs. Analyze the data by using CloudWatch Logs Insights
  
  B : Configure the NAT gateway to be a VPC traffic mirror source. Deploy software on the traffic mirror target to forward the data to an Amazon S3 bucket. Analyze the data by using Amazon Athena.
  
  C : Turn on VPC Flow Logs for the EC2 instances. Specify the default format and set Amazon CloudWatch Logs as the log destination. Analyze the flow log data by using CloudWatch Logs Insights.
  
  D : Turn on VPC Flow Logs for the EC2 instances. Specify a custom format and set Amazon S3 as the log destination. Analyze the flow log data by using Amazon Athena.
  
  Answer: A
Question 2
- A company has configured an AWS Cloud WAN core network with edge locations in the us-east-1 Region and the us-west-1 Region. Each edge location has two segments: development and staging. The segments use the default core network policy. The company has attached VPCs to the core network. A development VPC is attached to the development segment in us-east-1 and is configured to use the 10.0.0.0 CIDR block. A staging VPC is attached to the staging segment in us-west-1 and is configured to use the 10.5.0.0 CIDR block. The company has updated the route tables for both VPCs with a route that directs any traffic for 0.0.0.0/0 to the core network. The companys network team needs to establish communication between the two VPCs by using the AWS Cloud WAN core network. The network team is not receiving a response during tests of communication between the VPCs. The network team has verified that security groups and network ACLs are not blocking the traffic. What should the network team do to establish this communication?
  A : Update both VPC route tables to have a new static route. Configure a route on the development VPC to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route on the staging VPC to direct the traffic for 10.5.0.0 to the staging VPC attachment.
  
  B : Update the segment filter to allow traffic on the development and staging segments.
  
  C : Set the isolate-attachments parameter to False for the development and staging segments.
  
  D : Update the core network policy to add a static route for each segment. Configure a route to direct the traffic for 10.0.0.0 to the development VPC attachment. Configure a route to direct the traffic for 10.5.0.0 to the staging VPC attachment.
  
  Answer: D
Question 3
- A company has an on-premises data center in the United States. The data center is connected to AWS by an AWS Direct Connect connection. The data center has a private VIF that is connected to a Direct Connect gateway. Recently, the company opened a new data center in Europe and established a new Direct Connect connection between the Europe data center and AWS. A new private VIF connects to the existing Direct Connect gateway. The company wants to use Direct Connect SiteLink to set up a private network between the data center in the United States and the data center in Europe. Which solution will meet these requirements in the MOST operationally efficient manner?
  A : Create a new public VIF from each data center. Enable SiteLink on the new public VIFs.
  
  B : Create a new transit VIF from each data center. Enable SiteLink on the new transit VIFs.
  
  C : Use the existing VIF from each data center. Enable SiteLink on the existing private VIFs.
  
  D : Create a new AWS Site-to-Site VPN connection between the data centers. Configure the new connection to use SiteLink.
  
  Answer: C
Question 4
- A company wants to implement a distributed architecture on AWS that uses a Gateway Load Balancer (GWLB) and GWLB endpoints. The company has chosen a hub-and-spoke model. The model includes a GWLB and virtual appliances that are deployed into a centralized appliance VPC and GWLB endpoints. The model also includes internet gateways that are configured in spoke VPCs. Which sequence of traffic flow to the internet from the spoke VPC is correct?
  A : 1.An application in a spoke VPC sends traffic to the GWLB endpoint based on the VPC route table configuration.2. Traffic is delivered securely and privately to the GWLB.3. The GWLB sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB endpoint and out to the internet through the internet gateway.
  
  B : 1. An application in a spoke VPC sends traffic to the GWLB endpoint based on the VPC route table configuration.2. Traffic is delivered securely and privately to the GWLB endpoint.3. The GWLB sets the X-Forwarded-For request header and sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB and out to the internet through an internet gateway.
  
  C : 1. An application in a spoke VPC sends traffic to the GWLB endpoint.2. Traffic is delivered securely and privately to the GWLB.3. The GWLB sets the X-Forwarded-For request header and sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB endpoint and out to the internet through the internet gateway.
  
  D : 1. An application in a spoke VPC sends traffic to the GWLB.2. Traffic is delivered securely and privately to the GWLB endpoint.3. The GWLB sends the traffic to a virtual appliance for inspection.4. Return traffic flows back to the GWLB and out to the internet through an internet gateway.
  
  Answer: A
Question 5
- A company deployed an application in two AWS Regions in one AWS account. The company has one VPC in each Region. The VPCs use non-overlapping private CIDR ranges. The company needs to connect both VPCs to a single on-premises data center to test the application. The application requires up to 800 Mbps of throughput. A network engineer needs to establish connectivity between the VPCs and the on-premises data center. Which solution will meet this requirement with the LEAST operational overhead?
  A : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure static routes in the VPC route tables and in the data center router.
  
  B : Order a 2 Gbps Direct Connect connection for the data center. Configure a virtual private gateway in each VPC. Create a private VIF for each virtual private gateway, and associate the virtual private gateways with the Direct Connect connection. Configure Open Shortest Path First (OSPF) routing between the private VIF and the data center.
  
  C : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure static routes in each VPC route table to point to the subnets in the data center.
  
  D : Configure a customer gateway and a virtual private gateway in each VPC. Configure an AWS SitetoSite VPN connection between the data center and each VPC. Configure BGP routing between the VPCs and the data center.
