Network Appliance Implementation Engineer - SAN ONTAP Exam 認定 NS0-521 試験問題 (Q105-Q110):

質問 # 105
A LUN Is displaying 90% used space in the NetApp ONTAP CLI, but a Windows Server shows only 10% used space. What is the first step to take to address this issue?

正解：C

解説：
When a LUN shows 90% used space in the NetApp ONTAP CLI but a Windows Server shows only 10% used space, the discrepancy is often due to how space allocation is handled between the two systems. Enabling space allocation ensures that the ONTAP system accurately reflects the actual space usage as reported by the host system, in this case, the Windows Server. This adjustment allows ONTAP to reclaim and manage space more effectively, aligning the reported usage between the ONTAP system and the host.


質問 # 106
An administrator installs a new NetApp ONTAP system in a customer's SAN environment. The customer wants to confirm that ALUA correctly changes the path states between Active/Optimized and Active/Nonoptimized.
Which event causes ALUA to change the path states?

正解：C

解説：
ALUA (Asymmetric Logical Unit Access) is a protocol used in SAN environments to manage paths between a host and its storage. It enables the host to recognize and manage paths to the LUNs more efficiently by designating paths as either "Active/Optimized" or "Active/Nonoptimized". A significant event, such as shutting down all FC LIFs on the HA partner node, will trigger ALUA to change the pathstates. This action effectively causes the storage paths to transition from the HA partner node to the local node, switching the path states from Active/Nonoptimized to Active/Optimized on the paths that remain active.
For more information, you can refer to:
* NetApp Community Discussion on ALUA
* NetApp Documentation on ALUA


質問 # 107
What is the minimum number of rack units that are required on each site for a NetApp AFF All San Array (ASA) A800 MetroCluster IP configuration with 72 disks per site and Cisco N9K- C9336C-FX2 backend switches?

正解：B

解説：
A NetApp AFF ASA A800 node requires 4 rack units (RU) each. With two nodes per site, plus Cisco N9K-C9336C-FX2 backend switches (typically 1-2 RU each), the minimum combined rack space per site totals around 8 RU.


質問 # 108
What are two benefits of implementing VLANs for NVMe/TCP configurations? (Choose two.)

正解：A、C

解説：
Implementing VLANs for NVMe/TCP configurations provides several benefits, two of which are increased resiliency and increased security:
* Increased Resiliency: VLANs help segment the network traffic, reducing the risk of a single point of failure. By isolating NVMe/TCP traffic into specific VLANs, network issues can be contained within a VLAN, preventing them from affecting other parts of the network. This isolation ensures that disruptions are minimized and network resiliency is enhanced.
* Increased Security: VLANs provide an added layer of security by segregating traffic. This segregation ensures that NVMe/TCP traffic is isolated from other types of traffic, reducing the risk of unauthorized access or data breaches. VLANs help in enforcing stricter access controls and monitoring, thereby increasing the overall security of the network.
For more information on the benefits of VLANs in NVMe/TCP configurations, you can refer to NetApp's technical resources:
* Implementing and Configuring Modern SANs with NVMe-oF (NetApp).
* SAN Configuration Best Practices (NetApp Community).


質問 # 109
An administrator has a 2-node NetApp ONTAP cluster that is hosting FC LUNs for 90 SAN hosts.
The hosts are experiencing occasional performance problems and receiving QFULL responses from the cluster nodes. Which action would resolve this issue?

正解：B

解説：
Adding more FC target ports on the ONTAP cluster nodes increases available queue resources and paths, reducing queue full (QFULL) responses and improving SAN host performance.
