Answer: Review the Amazon CloudWatch metrics for VirtualInterfaceBpsEgress and VirtualInterfaceBpsIngress to determine which VIF is sending the highest throughput during the period in which slowness is observed. Create a new 10 Gbps dedicated connection. Shift traffic from the existing dedicated connection to the new dedicated connection.
To address the issue of sudden increases in throughput causing the Direct Connect connection to become saturated, the network engineer needs to identify which VIF (Virtual Interface) is responsible for the high throughput during the problematic period. This can be achieved by reviewing the Amazon CloudWatch metrics for VirtualInterfaceBpsEgress and VirtualInterfaceBpsIngress, which provide data on the throughput for each VIF. Once the problematic VIF is identified, the next step is to resolve the saturation issue. Option A suggests creating a new 10 Gbps dedicated connection and shifting traffic from the existing connection to the new one, which would effectively increase the available bandwidth and alleviate the saturation issue. Option B suggests upgrading the bandwidth of the existing dedicated connection to 10 Gbps, which would also increase the available bandwidth but does not involve creating a new connection. Both options A and B correctly identify the need to review the specific CloudWatch metrics to find the problematic VIF and propose viable solutions to increase bandwidth. However, since the question asks for one correct answer when four options are provided, and both A and B are correct, the most comprehensive solution that involves creating a new dedicated connection (Option A) is selected as the best answer. Options C and D are incorrect because they suggest reviewing the wrong CloudWatch metrics (ConnectionBpsIngress and ConnectionPpsEgress) which do not provide the necessary information to identify the problematic VIF.

A company has a 4 Gbps AWS Direct Connect dedicated connection with a LAG bundle connecting to five VPCs in the us-east-1 Region, each serving a different business unit with its own private VIF for on-premises connectivity. Users report slow access to AWS-hosted resources, and a network engineer observes sudden throughput spikes saturating the Direct Connect connection for about an hour daily. The company needs to identify which business unit is causing the throughput surge and implement a solution to address the issue. What solution meets these requirements?
A
Review the Amazon CloudWatch metrics for VirtualInterfaceBpsEgress and VirtualInterfaceBpsIngress to determine which VIF is sending the highest throughput during the period in which slowness is observed. Create a new 10 Gbps dedicated connection. Shift traffic from the existing dedicated connection to the new dedicated connection.
B
Review the Amazon CloudWatch metrics for VirtualInterfaceBpsEgress and VirtualInterfaceBpsIngress to determine which VIF is sending the highest throughput during the period in which slowness is observed. Upgrade the bandwidth of the existing dedicated connection to 10 Gbps.
C
Review the Amazon CloudWatch metrics for ConnectionBpsIngress and ConnectionPpsEgress to determine which VIF is sending the highest throughput during the period in which slowness is observed. Upgrade the existing dedicated connection to a 5 Gbps hosted connection.
D
Review the Amazon CloudWatch metrics for ConnectionBpsIngress and ConnectionPpsEgress to determine which VIF is sending the highest throughput during the period in which slowness is observed. Create a new 10 Gbps dedicated connection. Shift traffic from the existing dedicated connection to the new dedicated connection.
