Following a DNS migration, an NFS client can still mount a PowerScale export by using a node's data IP address. From that same client, a DNS query sent directly to the configured SmartConnect service IP returns a valid pool address. A query for the same SmartConnect name through the client's usual DNS resolver returns NXDOMAIN. Where is the fault most likely located?
Correct answer: C - The upstream DNS delegation for the SmartConnect zone
An eight-node PowerScale cluster has one node pool. Before an incident, the files under review had achieved +2d:1n protection. Two nodes then lose power together; the other six remain healthy and can communicate over the internal network. What can the engineer conclude about quorum and the protection level?
Correct answer: D - Five nodes are required for quorum; this protection level does not guarantee recovery from two node failures.
A customer is adding three F710 nodes to an F600 cluster and wants to retain one OneFS namespace. Software and network compatibility for the expansion have been confirmed. The proposed design places the F600 and F710 nodes in a single node pool because both platforms are all-flash. How should the hardware be organized instead?
Correct answer: B - Retain one cluster and place the three F710 nodes in a separate node pool.
A replacement request was opened when a PowerScale data drive entered SMARTFAIL. Before the replacement arrives, the technician checks the same drive with the CLI and finds that its state is now REPLACE. No one has exchanged the physical drive. This transition means that:
Correct answer: A - Smartfail processing has completed, and the drive is ready for replacement.
One PSU has failed in an F600 node. The other PSU is healthy, has a verified independent power source, and can sustain the node. No other hardware faults are present. An authorized customer technician has the approved replacement and the model-specific live-replacement procedure. The objective is to restore power redundancy without taking a serviceable node out of the cluster. Select the appropriate repair plan.
Correct answer: C - Replace the failed PSU online, wait 15 seconds, then check its green indicator and isi_hw_status.
An approved F600 DIMM-replacement request identifies a physical node serial number and DIMM slot A3. The request recorded that node as logical node number (LNN) 4. A subsequent, documented LNN change moved the same serial number to LNN 7; current LNN 4 belongs to a different physical node. The fault history still identifies the serial number on the request. Which service target is correct?
Correct answer: C - DIMM A3 on current LNN 7, after matching the physical serial number to the request.
Four F710 nodes will use independent A and B power feeds. Each feed must support all four nodes if the other feed fails and has 3,300 W of usable capacity remaining after other equipment is accounted for. At 200-240 V, the planning data gives a maximum of 769 W per node at 25 degrees C and 887 W at 35 degrees C; each node has dual 1,400-W PSUs. The design condition is 35 degrees C. Which assessment is correct?
Correct answer: D - 3,548 W on the surviving feed; the proposed feeds do not meet the failover requirement.
At rack installation, a 22.5-kg F710 node fits the available 1U opening. The rack itself is within its total load rating, but the only spare rail kit is rated for 20 kg and has not been approved for the F710. Its mounting holes appear to align. What must change before the node is mounted?
Correct answer: A - Fit the approved F710 rail kit, verified for the node's mounting points and loaded weight.
During an expansion of a OneFS 9.8 cluster, an incoming node appears in the unconfigured-node inventory. Its hardware compatibility, software release, and available internal addresses have been verified. The cluster uses secure join mode, and the serial-console option to join an existing cluster is unavailable. Site policy requires secure join mode to remain enabled. How can the administrator admit the node?
Correct answer: B - Authorize its serial number through the existing cluster's web administration interface.
The commissioning plan for three unconfigured PowerScale nodes calls for SmartLock Compliance mode. A draft sequence would first create an ordinary cluster, ingest the archive, and then activate a SmartLock license to enable Compliance mode. Which correction is necessary?
Correct answer: A - Select Compliance mode during initial cluster configuration, before activating the SmartLock license.
