An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
To create a fully redundant connection from your on-premises data center to your Virtual Cloud Network (VCN) in the us-ashburn-1 region, you need to ensure that there are multiple pathways for data to travel, so that if one path fails, the other can continue to function. Here are the options that meet this requirement:
Configure one FastConnect virtual circuit to the us-ashburn-1 region and a Site-to-Site VPN to the us-ashburn-1 region.
FastConnect provides a private, high-bandwidth connection between your on-premises network and the cloud network. By establishing one FastConnect circuit here, you have one reliable, low-latency direct link to the cloud.
A Site-to-Site VPN serves as a secondary path that is secure and encrypted over the public internet. Though it might offer lower performance than FastConnect, it provides redundancy in case the FastConnect circuit fails.
Using both methods ensures that if one connection (either FastConnect or VPN) faces disruption, the other can continue to handle traffic.
Configure two FastConnect virtual circuits to the us-ashburn-1 region and terminate them in diverse hardware on-premises.
By setting up two FastConnect circuits, you create a primary and secondary high-speed, low-latency private connection to the cloud.
The diversity in terminating them in separate hardware on-premises increases the redundancy, as failure in one hardware setup won't affect the other connection.
In the event of a failure on one line or hardware, the second FastConnect link can still provide connectivity.
These configurations offer robust redundancy, ensuring continuous connectivity to your VCN in the event of a failure in one of the connections.
The total charge delivered by a device with a current of 15.0 A for 30 seconds is 450 coulombs. This corresponds to approximately 2.81 x 10^21 electrons flowing through the device. The calculations use the relationship between current, charge, and time along with the charge of an electron.
