An IT organization wants to deploy four FC switches for compute and storage system connectivity. To meet performance requirements, a maximum of one active ISL and redundant ISLs for their compute to storage traffic.Which FC SAN topology should be recommended?
Answer(s): C
multi-switch topology is the best recommendation for your requirements. With this topology, you can have multiple ISLs connecting the switches, allowing for redundancy and improved performance. You can also configure trunking and load balancing policies on the ISLs to ensure sufficient bandwidth and guarantee the order of delivery.
What is a purpose of the policy engine in a data archiving environment?
Answer(s): B
The purpose of the policy engine in a data archiving environment is to automate the process of moving the appropriate data from primary storage into archive storage. It does this by monitoring data access patterns in primary storage and automatically moving the data that is least accessed into an archive storage device. This process allows for more efficient use of primary storage and also reduces storage costs.
Which management monitoring parameter involves examining the amount of infrastructure resources used?
Capacity is a management monitoring parameter that involves examining the amount of infrastructure resources used. This includes monitoring storage capacity, network bandwidth, CPU utilization, memory usage, and other resources. Capacity management is important for ensuring that the infrastructure has sufficient resources to meet the demands of the business or customers. It involves predicting future resource needs, identifying capacity bottlenecks, and optimizing resource utilization to avoid performance degradation or service disruptions.

A Fibre Channel switch has eight ports and all ports must be operational from 6 AM to 6 PM, Monday through Friday.However, a failure of Port 4 occurs with the week as follows:Monday= 11 AM to 1 PMWednesday= 5 PM to 10 PMThursday= 7 AM to 10 AMSaturday= 11 AM to 1 PMWhat is the availability of Port 4 in that week?
To calculate availability, you need to calculate the total number of hours that the port is operational and divide it by the total number of hours in the week, which is 168. The total number of hours that Port 4 is operational in that week is 106.7, so the availability is 106.7/168 = 86.7%.
