A company hosts several applications in the AWS Cloud across multiple VPCs that are connected to a transit gateway Redundant AWS Direct Connect connections and a Direct Connect gateway provide private network connectivity lo the company's on-premises environment
During a maintenance window, the networking team adds eight VPCs The application management team notices that there is no reachability between the newly created VPCs and the on-premises environment Connectivity between all VPCs through the transit gateway is working as expected.
Which of the following are possible causes of the connectivity issues? (Choose TWO)

A company's developers wrote an AWS Lambda function to modify existing private route tables in response to a security appliance's auto scaling events. The Lambda function will be invoked on lifecycle hooks for an Auto Scaling group and Is configured to run in a VPC The developers are unsure if the following 1AM policy provides sufficient permissions to be used as an execution role for this Lambda function.

A customer is using ABC Telecom as a network provider. The customer has 10 different offices connected to ABC Telecom’s MPLS backbone. The customer is setting up an AWS Direct Connect connection to AWS and has provided the LOA-CFA to ABC Telecom. ABC Telecom has terminated the Direct Connect circuit into their MPLS backbone. To uniquely identify the customer’s traffic over the MPLS backbone, the customer must encapsulate all traffic with VLAN tag 100. The customer wants to send traffic to multiple VPCs.
Which two steps should be taken to meet the customer’s requirement? (Select two.)
A manufacturing company has a hybrid environment that includes an AWS Direct Connect gateway that is associated with an AWS Transit Gateway The company wants to extend a third-party application that is hosted in its on-premises data center into one of its VPCs
The application vendor has stated that It must use an overlay IP address to meet the company's requirement for high availability. The DHCP administrator has assigned a non-overlapping RFC1918 private address for use as the overlay IP address The security team requires connectivity to remain private
Which solution meets these requirements with the LEAST management overhead''
An organization has created a web application inside a VPC and wants to make it available to 200 client VPCs. The client VPCs are in the same region but are owned by other business units within the organization.
What is the best way to meet this requirement, without making the application publicly available?
A company uses AWS Direct Connect lo connect its corporate network to multiple VPCs in the same AWS account and the same AVVS Region Each VPC uses its own private VIF and its own virtual LAN on the Direct Connect connection The company has grown and will soon surpass the limit of VPCs and private VIFs for each connection
What is the MOST scalable way to add VPCs with on-premises connectivity?
