Question

Looking at the existing error, you suspect that most of the issues could be resolved with different repositories. Assuming the repositories will be able to accomplish much higher throughput, what new issue might come up?

Options

AThe bandwidth between sites might not be sufficient.
BThe repository space consumption could decrease
CThe production firewall could become a bottleneck
DThe increased backup speed could completely bring down production storage.

Explanation

If the repositories are able to accomplish much higher throughput, a new issue that might come up is that the bandwidth between sites might not be sufficient to support the backup copy jobs that need to run daily between Fresno and Carson City. This could cause the backup copy jobs to fail, take longer than expected, or consume too much network resources. Therefore, it is important to measure the available bandwidth between the sites and compare it with the backup copy data size and window. If the bandwidth is not sufficient, some possible solutions are to use compression, deduplication, or WAN acceleration to reduce the backup copy traffic.
