Questions # 2:

A Storage Administrator is adding an appliance into an existing Dell PowerStore T cluster.

What is different about the management network configuration for the new appliance compared to configuring an initial appliance for the cluster?

Options:

All the needed management IP addresses for the new appliance must be pre-configured on the cluster

Additional appliance does not require a cluster management IP address

Additional appliance inherits all its management IPs from the existing appliance

All the needed management IP addresses for the new appliance are auto-generated by the cluster

Answer

Explanation

Each appliance must have Management and Storage networks configured. Management networks connect the cluster to management services such as DNS, NTP, and vCenter. The management network also enables external clients to access the cluster. The Storage network connects the cluster to an existing storage network or establishes a new network within the cluster. It also enables external clients to access the storage in the cluster. Both the Management and Storage networks require at least three IP addresses

A Storage Administrator notices two fans in a Dell PowerStore are faulted. What describes the system behavior in this circumstance?

Options:

A five-minute timer starts upon the second fan fault and the system shuts down automatically after the timer expires

CPU clock speed is reduced by 50% to lower internal temperatures and the system continues normal operations

An increased fan speed signal is sent to the surviving fans and the system continues normal operations

Upon the second fan fault, all host I/O is terminated immediately and the PowerStore goes through the halt and vault process and shuts down

Answer

Explanation

1. Run vlt-domain to create a new VLTi domain.

2. Run discovery-interface ethernet chassis/slot/portchassis/slot/port to add the two VLTi ports to the new domain. 3. Run backup destination to set the other switch as VLT backup, which is required for VLT heartbeat. #(conf-range-eth1/1/55-1/1/56) vlt-domain 1 #(conf-vlt-1) discovery-interface ethernet 1/1/55-1/1/56 #(conf-vlt-1) backup destination 172.17.57.30
