Exam DES-1D12 topic 1 question 43 discussion

System bond PowerStore systems ensure that there is no single point of failure throughout the system. For a PowerStore T model appliance, it is recommended to cable the first two ports of the 4-port card to a top-of-rack switch as shown in Figure 24. For the PowerStore T model, these ports are internally referred to as the system bond. This interface is created to ensure that there is no single point of failure and data services and production data are always available. Below shows a list of different types of traffic that flows through the system bond if the data services are leveraged on the PowerStore system: • Management traffic (for PowerStore X models) • Cluster communication • iSCSI host traffic • Replication traffic • NAS traffic (for PowerStore T models) Dell EMC PowerStore: Introduction to the Platform | H18149.6

NAS Network Heartbeat enables data service high availability (HA) which results in NAS server failover when a threshold is reached. The heartbeat is conducted at fixed intervals of 1 second A is correct

I disagree. Read the question. It's more general. The thing that makes PowerStore so HA is all the redundant components built into the platform including networking and bonding. If you check out the Powerstore Cluster and HA white paper https://www.delltechnologies.com/en-us/collaterals/unauth/white-papers/products/storage/h18157-dell-emc-powerstore-clustering-high-availability.pdf there is no mention of heartbeat which is important for NAS i will grant you but it's the redundancy of components which is the heart of HA in PowerStore (since it does both block and NAS)

A is correct
