(Choose three.)Select one or more:failure to design for reliabilityfailure to identify management issuesfailure to detect errors as they occurfailure to prevent security incidentssingle points of failurefailure to protect against poor maintenance
Question
A user is asked to evaluate the data center to improve availability for customers. The user notices that there is only one ISP connection, some of the equipment is out of warranty, there are no spare parts, and no one was monitoring the UPS which was tripped twice in one month. Which three deficiencies in high availability has the user identified? (Choose three.)Select one or more:failure to design for reliabilityfailure to identify management issuesfailure to detect errors as they occurfailure to prevent security incidentssingle points of failurefailure to protect against poor maintenance
Solution
The three deficiencies in high availability that the user has identified are:
-
Single points of failure: This is evident from the fact that there is only one ISP connection. If this connection fails, the entire data center would lose internet connectivity, causing a significant disruption in service.
-
Failure to design for reliability: The equipment being out of warranty and the lack of spare parts indicates a lack of planning for reliability. Equipment can fail, and without warranty or spare parts, it can take a significant amount of time to repair or replace, leading to downtime.
-
Failure to protect against poor maintenance: The fact that no one was monitoring the UPS, which was tripped twice in one month, shows a lack of proper maintenance. Regular monitoring and maintenance of equipment is crucial for high availability.
