Ultimate access to all questions.
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.
