A company has two on-premises data center locations. There is a company-managed router at each data center. Each data center has a dedicated flaws Direct Connect connection to a Direct Connect gateway through a private virtual interface. The router for the first location is advertising 110 routes to the Direct Connect gateway by using BGP, and the router for the second location is advertising 60 routes to the Direct Connect gateway by using BGP. The Direct Connect gateway is attached to a company VPC through a virtual private gateway.A network engineer receives reports that resources in the VPC are not reachable from various locations in either data center. The network engineer checks the VPC route table and sees that the routes from the first data center location are not being populated into the route table. The network engineer must resolve this issue in the most operationally efficient manner.What should the network engineer do to meet these requirements?

A company has expanded its network to the flaws Cloud by using a hybrid architecture with multiple flaws accounts. The company has set up a shared flaws account for the connection to its on-premises data centers and the company offices. The workloads consist of private web-based services for internal use. These services run in different flaws accounts. Office-based employees consume these services by using a DNS name in an on-premises DNS zone that is named example.internal.The process to register a new service that runs on flaws requires a manual and complicated change request to the internal DNS. The process involves many teams.The company wants to update the DNS registration process by giving the service creators access that will allow them to register their DNS records. A network engineer must design a solution that will achieve this goal. The solution must maximize cost-effectiveness and must require the least possible number of configuration changes.Which combination of steps should the network engineer take to meet these requirements? (Choose three.)

A company has multiple flaws accounts. Each account contains one or more VPCs. A new security guideline requires the inspection of all traffic between VPCs.The company has deployed a transit gateway that provides connectivity between all VPCs. The company also has deployed a shared services VPC with Amazon EC2 instances that include IDS services for stateful inspection. The EC2 instances are deployed across three Availability Zones. The company has set up VPC associations and routing on the transit gateway. The company has migrated a few test VPCs to the new solution for traffic inspection.Soon after the configuration of routing, the company receives reports of intermittent connections for traffic that crosses Availability Zones.What should a network engineer do to resolve this issue?

A company operates its IT services through a multi-site hybrid infrastructure. The company deploys resources on flaws in the us-east-1 Region and in the eu-west-2 Region. The company also deploys resources in its own data centers that are located in the United States (US) and in the United Kingdom (UK). In both flaws Regions, the company uses a transit gateway to connect 15 VPCs to each other. The company has created a transit gateway peering connection between the two transit gateways. The VPC CIDR blocks do not overlap with each other or with IP addresses used within the data centers. The VPC CIDR prefixes can also be aggregated either on a Regional level or for the company’s entire flaws environment.The data centers are connected to each other by a private WAN connection. IP routing information is exchanged dynamically through Interior BGP (iBGP) sessions. The data centers maintain connectivity to flaws through one flaws Direct Connect connection in the US and one Direct Connect connection in the UK. Each Direct Connect connection is terminated on a Direct Connect gateway and is associated with a local transit gateway through a transit VIF.Traffic follows the shortest geographical path from source to destination. For example, packets from the UK data center that are targeted to resources in eu-west-2 travel across the local Direct Connect connection. In cases of cross-Region data transfers, such as from the UK data center to VPCs in us-east-1, the private WAN connection must be used to minimize costs on flaws. A network engineer has configured each transit gateway association on the Direct Connect gateway to advertise VPC-specific CIDR IP prefixes only from the local Region. The routes toward the other Region must be learned through BGP from the routers in the other data center in the original, non-aggregated form.The company recently experienced a problem with cross-Region data transfers because of issues with its private WAN connection. The network engineer needs to modify the routing setup to prevent similar interruptions in the future. The solution cannot modify the original traffic routing goal when the network is operating normally.Which modifications will meet these requirements? (Choose two.)

A company uses a 4 Gbps flaws Direct Connect dedicated connection with a link aggregation group (LAG) bundle to connect to five VPCs that are deployed in the us-east-1 Region. Each VPC serves a different business unit and uses its own private VIF for connectivity to the on-premises environment. Users are reporting slowness when they access resources that are hosted on flaws.A network engineer finds that there are sudden increases in throughput and that the Direct Connect connection becomes saturated at the same time for about an hour each business day. The company wants to know which business unit is causing the sudden increase in throughput. The network engineer must find out this information and implement a solution to resolve the problem.Which solution will meet these requirements?

All of the provider’s customers also have their environments in the flaws Cloud.A recent design meeting revealed that the customers have IP address overlap with the provider’s flaws deployment. The customers have stated that they will not share their internal IP addresses and that they do not want to connect to the provider’s SaaS service over the internet.Which combination of steps is part of a solution that meets these requirements? (Choose two.)

A company is using custom DNS servers that run BIND for name resolution in its VPCs. The VPCs are deployed across multiple flaws accounts that are part of the same organization in flaws Organizations. All the VPCs are connected to a transit gateway. The BIND servers are running in a central VPC and are configured to forward all queries for an on-premises DNS domain to DNS servers that are hosted in an on-premises data center. To ensure that all the VPCs use the custom DNS servers, a network engineer has configured a VPC DHCP options set in all the VPCs that specifies the custom DNS servers to be used as domain name servers.Multiple development teams in the company want to use Amazon Elastic File System (Amazon EFS). A development team has created a new EFS file system but cannot mount the file system to one of its Amazon EC2 instances. The network engineer discovers that the EC2 instance cannot resolve the IP address for the EFS mount point fs-33444567d.efs.us-east-1.amazonaws.com. The network engineer needs to implement a solution so that development teams throughout the organization can mount EFS file systems.Which combination of steps will meet these requirements? (Choose two.)
