QUESTION: 17

What is represented by the Headroom graph on the SANtricity System Manager performance tab?

the percentage of I/O associated with the backend disk drives
the remaining performance capability of the physical objects in the storage system
the percentage of CPU processing capacity that is being used by the operations on the system
the resources that are being consumed by a defined workload

Answer(s): B

Explanation:

The Headroom graph in SANtricity System Manager shows the remaining performance capability of the physical objects (e.g., disks, SSDs) in the storage system. This helps in understanding how much additional load the system can handle before reaching its performance limits.

Reference:

NetApp SANtricity System Manager User Guide, which explains the performance monitoring features.

QUESTION: 18

To enable one-way authentication in a new iSCSI Linux implementation, which three modifications should you make in the /etc/iscsi/iscsid.conf file on the Linux host? (Choose three.)

the target username and password
the initiator username and password
CHAP
sendtargets discovery
iSCSI

Answer(s): A,B,C

Explanation:

Target username and password: These credentials are used by the initiator to authenticate to the target.
Initiator username and password: These credentials are used by the target to authenticate the initiator.
CHAP: Challenge-Handshake Authentication Protocol is used to set up the authentication mechanism.
Modifications in the /etc/iscsi/iscsid.conf file include setting the appropriate values for these parameters.

Reference:

NetApp iSCSI Configuration Guide for Linux, which details the configuration of CHAP and other authentication methods.

QUESTION: 19

Which two errors would fail a pre-upgrade health check? (Choose two.)

Hot spares are in use
Volumes are reported on a non-preferred path
An excess number of event log events are present
I/O is being processed

Answer(s): B,D

Explanation:

Understand Pre-Upgrade Health Check:
Purpose: The pre-upgrade health check is designed to ensure the system is in a stable state before proceeding with firmware or software upgrades. This helps to avoid disruptions and data loss.
Volumes on Non-Preferred Path (B):
Issue: If volumes are reported on a non-preferred path, it indicates that there might be a pathing issue or an imbalance in the I/O load.
Impact: Non-preferred paths can lead to performance degradation and increased latency, which might cause issues during the upgrade process.
Resolution: Ensure that all volumes are accessible through their preferred paths before initiating the upgrade.

Reference:

NetApp E-Series Upgrade and Health Check Documentation.
I/O Being Processed (D):

Issue: Active I/O during the upgrade process can lead to incomplete or failed upgrades. Impact: Processing I/O during an upgrade can result in data corruption or loss, and may also cause the upgrade to fail.
Resolution: Suspend or stop all I/O operations on the system before starting the upgrade.
