A global company runs business applications in the us-east-1 Region inside a VPC. One of the company's regional offices in London uses a virtual private gateway for an AWS Site-to-Site VPN connection tom the VPC. The company has configured a transit gateway and has set up peering between the VPC and other VPCs that various departments in the company use.
Employees at the London office are experiencing latency issues when they connect to the business applications.
What should a network engineer do to reduce this latency?
A software-as-a-service (SaaS) company is migrating its private SaaS application to AWS. The company has hundreds of customers that connect to multiple data centers by using VPN tunnels. As the number of customers has grown, the company has experienced more difficulty in its effort to manage routing and segmentation of customers with complex NAT rules.
After the migration to AWS is complete, the company's AWS customers must be able to access the SaaS application directly from their VPCs. Meanwhile, the company's on-premises customers still must be able to connect through IPsec encrypted tunnels.
Which solution will meet these requirements?
A company has multiple AWS Site-to-Site VPN connections between an on-premises environment and multiple VPCs. The Site-to-Site VPN connections use virtual private gateways and are configured with IPv4 addresses. The company hosts several internal applications in the VPCs.
Application users have reported that the applications are performing slowly. A networkengineer notices excessive latency in the network path that the VPN connections use. The network engineer needs to resolve the excessive latency.
Which solution will meet this requirement?
A company runs workloads in multiple VPCs. The company needs to securely access a workload in one of the VPCs, named VPC-A, from an on-premises data center. A network engineer sets up an AWS Site-to-SiteVPN connection to a transit gateway. The network engineer configures dynamic routing for the connection, and communication works properly.
Recently, the owner of VPC-A added another CIDR range to the VPC. The VPC-A owner created workloads that use the additional CIDR range.
The company's on-premises network is unable to reach the new workloads. The network engineer needs to resolve the network connectivity issue and ensure that connectivity will not be affected if additional VPC CIDR ranges are added to the VPC in the future.
Which solution will meet these requirements with the MOST operational efficiency?
A company has two AWS Direct Connect links. One Direct Connect link terminates in the us-east-1 Region, and the other Direct Connect link terminates in the af-south-1 Region. The company is using BGP to exchange routes with AWS.
How should a network engineer configure BGP to ensure that af-south-1 is used as a secondary link to AWS?
A real estate company is using Amazon Workspaces to provide corporate managed desktop service to its real estate agents around the world. These Workspaces are deployed in seven VPCs. Each VPC is in a different AWS Region.
According to a new requirement, the company’s cloud-hosted security information and events management (SIEM) system needs to analyze DNS queries generated by the Workspaces to identify the target domains that are connected to the Workspaces. The SIEM system supports poll and push methods for data and log collection.
Which solution should a network engineer implement to meet these requirements MOST cost-effectively?
A company needs to manage Amazon EC2 instances through command line interfaces for Linux hosts and Windows hosts. The EC2 instances are deployed in an environment in which there is no route to the internet. The company must implement role-based access control for management of the instances. The company has a standalone on-premises environment.
Which approach will meet these requirements with the LEAST maintenance overhead?
A real estate company is building an internal application so that real estate agents can upload photos and videos of various properties. The application will store these photos and videos in an Amazon S3 bucket as objects and will use Amazon DynamoDB to store corresponding metadata. The S3 bucket will be configured to publish all PUT events for new object uploads to an Amazon Simple Queue Service (Amazon SQS) queue.
A compute cluster of Amazon EC2 instances will poll the SQS queue to find out about newly uploaded objects. The cluster will retrieve new objects, perform proprietary image and video recognition and classification update metadata in DynamoDB and replace the objects with new watermarked objects. The company does not want public IP addresses on the EC2 instances.
Which networking design solution will meet these requirements MOST cost-effectively as application usage increases?
A company is growing rapidly. Data transfers between the company's on-premises systems and Amazon EC2 instances that run in VPCs are limited by the throughput of a single AWS Site-to-Site VPN connection between the company's on-premises data center firewall and an AWS Transit Gateway.
A network engineer must resolve the throttling by designing a solution that is highly available and secure. The solution also must scale the VPN throughput from on premises to the VPC resources to support the increase in traffic.
Which solution will meet these requirements?
A company has set up a NAT gateway in a single Availability Zone (AZ1) in a VPC (VPC1) to access the internet from Amazon EC2 workloads in the VPC. The EC2 workloads are running in private subnets in three Availability Zones (AZ1, AZ2, AZ3). The route table for each subnet is configured to use the NAT gateway to access the internet.
Recently during an outage, internet access stopped working for the EC2 workloads because of the NAT gateway's unavailability. A network engineer must implement a solution to remove the single point of failure from the architecture and provide built-in redundancy.
