Question 1

Which three techniques are used in ONTAP to improve storage efficiencies? (Choose three.)

Accepted Answer

A, C, E

Explanation: NetApp ONTAP employs a suite of storage efficiency technologies to reduce the storage footprint. Compression: Reduces the space required for data by using algorithms to remove redundant data within blocks. ONTAP offers both inline and post-process compression. Compaction: A space-saving feature that combines multiple data blocks that are not full into a single 4KB physical block on the disk, which is particularly effective for files with small I/O operations. Thin Provisioning: Allows volumes and LUNs to be provisioned with more logical space than is physically allocated. Physical storage is consumed only as data is written, improving storage utilization and deferring storage purchases.

Question 2

For security reasons, you must track the access of files of a specific folder. In this scenario, what should you do to accomplish this task from the storage side?

Accepted Answer

D

Explanation: FPolicy is a NetApp ONTAP framework designed for file access monitoring and management. It enables an administrator to create policies that monitor file operations (such as open, read, write, and close) on specific volumes or qtrees (folders). When a monitored event occurs, ONTAP sends a notification to an external FPolicy server. This server can then log the access event, creating a detailed audit trail for security and compliance purposes. This directly addresses the requirement to track file access within a specific folder from the storage system.

Question 3

You observe cyclic redundancy check (CRC) errors on a network port from a node in the cluster.
Which two components would you consider reseating or replacing before you perform actions on the
physical port where the errors are reported from the node? (Choose two.)

Accepted Answer

A, D

Explanation: Cyclic Redundancy Check (CRC) errors are physical layer (Layer 1) issues that indicate data corruption during transmission over a network link. The most common causes for these errors are problems with the physical media. Standard troubleshooting methodology dictates that the most easily replaceable and common points of failure should be addressed first. Therefore, before suspecting a fault with the node's physical port or the switch, it is best practice to reseat or replace the SFP/SFP+ transceiver and the network cable connecting the node to the switch.

Question 4

Your Windows clients were able to access your CIFS SVM yesterday. Today they are no longer able to
access the CIFS SVM on your NetApp cluster. Your IT security team just pushed out a new group
policy to enhance security.
In this scenario, which statement is true?

Accepted Answer

A

Explanation: A common security enhancement deployed via Group Policy is the disabling of legacy name resolution protocols, such as NetBIOS over TCP/IP (NBT-NS) and Link-Local Multicast Name Resolution (LLMNR), to mitigate "man-in-the-middle" attacks. If the Windows clients were previously relying on one of these less secure methods to resolve the CIFS SVM's name, and the SVM was not properly configured with or registered in DNS, the new policy would cause name resolution to fail. This would prevent clients from locating the SVM or its domain controllers, thus breaking access. The security policy did not cause the issue directly but exposed a pre-existing, fundamental misconfiguration.

Question 5

A customer is showing disk utilization is at 100% in Active IQ even though there are low protocol operations on the controller. You review the data shown in the exhibit. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-194/page_24_img_1.jpg In this situation, what should you do?

Accepted Answer

C

Explanation: The exhibit shows performance statistics where the RAID and Disk columns are at 100% utilization, while the CPU and other front-end protocol statistics are very low. This specific pattern indicates that the storage system is busy with a background process at the disk level, rather than serving client requests. A disk reconstruction, which is triggered by a failing or failed disk, is the most common cause for this symptom. The RAID layer is working at maximum capacity to rebuild the data from the failed disk onto a spare disk. Therefore, the correct action is to identify and replace the specific failing disk.

Question 6

After a network card was replaced in an ONTAP node, you see the output shown in the exhibit. https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-194/page_22_img_1.jpg What is the problem?

Accepted Answer

D

Explanation: The exhibit displays a multimodelacp interface group (ifgrp) where one port (e0c) is active (up) and the other (e0d) is inactive (down). In an LACP configuration, both the ONTAP node and the connected switch must be correctly configured for the link aggregation. The fact that one port is up while the other is down strongly suggests that LACP negotiation has failed specifically for the e0d link. This is a classic symptom of the port being cabled to a switch port that is not configured to be part of the same LACP bundle, which constitutes a mis-cabling or switch-side configuration error.

Question 7

A customer receives the message shown below in their EMS logs.
Tue Jun 27 18:34:18 CEST
[netapp-ct1: cp_worker: wafl.cp.toolong:error]: Aggregate AG1_NTAP_PROD experienced a long CP.
Tue Jun 27 18:37:10 CEST
Which two data sources do you use to explain this message? (Choose two.)

Accepted Answer

A, C

Explanation: The EMS message wafl.cp.toolong indicates a performance issue where a WAFL Consistent Point (CP) took longer than the allowed threshold. This is typically caused by a heavy, sustained write workload. To investigate and explain this performance event, an administrator would use NetApp's primary performance monitoring tools. Active IQ Unified Manager is the main tool for historical performance analysis. It collects detailed metrics over time, allowing an administrator to correlate the timestamp of the EMS message with specific workload spikes (IOPS, throughput), latency increases, or high resource utilization (CPU, disk) that caused the long CP. ONTAP System Manager provides real-time and recent historical performance dashboards directly on the cluster. It can be used for an immediate assessment of the current system state and to review performance charts for the time surrounding the event.

Question 8

Several clients are accessing an ONTAP SnapMirror DP destination volume. Some clients frequently
access the newest SnapMirror volume dat
a. Accessing this data is much slower when compared to clients that directly access data on the
source. You use the wafl scan status command against the destination.
What is a symptom of the problem in this scenario?

Accepted Answer

D

Explanation: When data is transferred to a SnapMirror destination volume, it is initially written in a non-optimized format to accelerate the transfer speed. After the transfer completes, a background WAFL (Write Anywhere File Layout) scanner process called "volume deswizzling" runs on the destination. This process reorganizes the newly written data blocks into a read-optimized layout. If clients access this new data before or during the deswizzling process, they will experience significantly slower read performance. The wafl scan status command would show the "deswizzle" scanner as active, which is the primary symptom of this performance issue.

Question 9

A customer has reported an unexplained reboot of an ONTAP node that did not generate a panic
string or a core file.
In this scenario, which two sets of logs do you collect to further diagnosis the issue? (Choose two.)

Accepted Answer

C, D

Explanation: When an ONTAP node reboots without generating a core file or a panic string, the cause is typically not a standard ONTAP software panic. The investigation must focus on hardware-level events or externally initiated reboots. The detailed Service Processor (SP) logs, accessed via sp status -d, are critical as the SP operates independently of ONTAP and records low-level hardware events, environmental alerts, power cycles, and console activity. The system-level event logs, collected with events all, provide a chronological timeline of ONTAP software events, which can reveal warnings or activities that occurred immediately before the unexpected shutdown, helping to correlate events and determine the root cause.

Question 10

While troubleshooting client access issues to a CIFS share, you notice that the issue only occurs when
the data LIF that the clients are accessing is on a specific node in the cluster.
In this scenario, which configuration should you review to determine why this issue is happening?

Accepted Answer

B

Explanation: The problem is isolated to a specific node when it hosts the CIFS data LIF. This indicates a node-specific configuration or state issue rather than a cluster-wide or SVM-wide problem. CIFS authentication, particularly Kerberos, is a primary candidate. Kerberos is time-sensitive and requires that the clock on the storage node be synchronized with the Key Distribution Center (KDC), which is typically a domain controller. If a single node has a significant clock skew or a broken secure channel to the domain controller, Kerberos authentication will fail for any client connections landing on a LIF hosted by that node.

Question 11

The details from within Active IQ Cluster Viewer are downloadable in which three file formats? (Choose three.)

Accepted Answer

A, B, C

Explanation: NetApp Active IQ's Cluster Viewer provides a comprehensive overview of a specific ONTAP cluster's configuration, health, and efficiency. To support offline analysis, reporting, and data integration with other tools, Active IQ allows users to download the detailed information presented in the Cluster Viewer. The platform offers three standard file formats for this purpose: PDF for a printable, formatted report; CSV for raw, comma-separated data suitable for scripting or database import; and XLS for a formatted spreadsheet compatible with Microsoft Excel.

Question 12

https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/NetApp_NS0-194/page_17_img_1.jpg Referring to the exhibit, the UNIX user "prof1" will be looked up in which source first?

Accepted Answer

D

Explanation: The exhibit displays the output of the vserver name-service ns-switch show command, which defines the lookup order for various name service databases. The question asks for the lookup source for a UNIX user, "prof1". In ONTAP, UNIX user information is resolved using the passwd database. According to the configuration shown for the passwd database, the sources are listed in the order they will be queried: files, then ldap. Therefore, ONTAP will first search the local files source for the user "prof1".

Question 13

When using NetApp Volume Encryption (NVE) which type of server is needed to keep encryption keys separate from encrypted data?

Accepted Answer

A

Explanation: NetApp Volume Encryption (NVE) allows for keys to be managed either by an onboard key manager or by an external key management server (KMS). To achieve the security goal of keeping encryption keys separate from the encrypted data, an external KMS must be used. ONTAP systems communicate with these external servers using the industry-standard Key Management Interoperability Protocol (KMIP). Therefore, a KMIP-compliant server is the required type to manage and serve encryption keys for NVE when external key management is implemented.

Question 14

A customer must store physical hard copies of transaction data off site to meet regulatory requirements. Which NetApp technology enables the customer to accomplish this task?

Accepted Answer

B

Explanation: The requirement is to store physical hard copies of data off-site, which in the context of data centers, refers to tape backups. Network Data Management Protocol (NDMP) is an industry-standard protocol used by NetApp ONTAP to enable backup applications to control the backup and restore of data between a storage system and tape devices. This allows for the creation of physical tape media that can be transported and stored at an off-site location, directly fulfilling the customer's regulatory compliance needs for physical, off-site data retention.

Question 15

A customer asks what is the correct way to configure an ONTAP system for multi-tenancy. The
customer wants to serve data and also protect data using SnapMirror from tenant A using network A
and from tenant B using network B.
In this scenario, which statement is correct?

Accepted Answer

C

Explanation: The correct way to achieve complete network isolation for multi-tenancy in ONTAP is by using IPspaces. An IPspace is a logical container that creates a distinct IP network stack, including its own routing table, firewall policies, and set of network interfaces (LIFs). By creating one IPspace for tenant A and another for tenant B, all network traffic for each tenant, including data access and SnapMirror replication, is kept completely separate. This configuration allows for non-overlapping network administration and even permits the use of overlapping IP address ranges between tenants on the same physical cluster.
