A bank’s transactional services are exclusively conducted online via Internet and mobile banking. Both its primary and disaster recovery sites are supported by the same Internet service provider (ISP). Which of the following is the BEST way for the bank to minimize risk in this situation?
A bank that relies solely on one Internet Service Provider (ISP) for both its primary and disaster recovery sites faces a significant risk due to the single point of failure. Establishing a contractual agreement with a second ISP to cover the connection to the disaster recovery site ensures redundancy in internet connectivity. This approach minimizes the risk of a complete network outage by maintaining internet access even if the primary ISP experiences issues. Therefore, the most effective way to minimize risk in this situation is to have an alternative ISP in place.
Because C: may help to reduce the risk of downtime due to network outages, but it does not address the issue of a single point of failure.
D. Establish a contractual agreement with a second ISP to cover connection to the disaster recovery site
D is better
D. The answer should be D
To avoid single point of failure, secondary ISP is needed
I am currently studying towards this certification and i wanted to know which answer is should consider, the one making sense or the one they nominated Please those who passed can you help?
D. Establish a contractual agreement with a second ISP to cover connection to the disaster recovery site. The best way for the bank to minimize risk in this situation is to have redundancy in its internet connectivity to the disaster recovery site. Currently, both the primary and disaster recovery sites are supported by the same Internet service provider (ISP), which creates a single point of failure. If this ISP experiences an outage or other issues, it could disrupt both the primary and disaster recovery operations. By establishing a contractual agreement with a second ISP to cover the connection to the disaster recovery site, the bank ensures that it has a backup internet connection. This redundancy reduces the risk of downtime or data loss in the event of a connectivity issue with the primary ISP. This approach enhances the bank's business continuity and disaster recovery capabilities.
