Which three factors should you consider before you install an E2860 in a data center? (Choose three.)
A,B,E
Explanation:
Current Draw: It is important to consider the electrical current draw of the E2860 to ensure that the
data center power infrastructure can support it without overloading circuits.
Heat Dissipation: The heat generated by the E2860 needs to be accounted for in the data center’s
cooling design. Proper heat dissipation mechanisms must be in place to prevent overheating.
Ambient Temperatures: The operating environment’s temperature should be within the specified
range for the E2860 to function correctly and reliably. Ensuring that the ambient temperatures are
controlled is crucial for optimal performance and longevity of the equipment.

You are setting up asynchronous mirroring between two E2860 systems.
In this scenario, which two prerequisites are required to complete the setup? (Choose two.)
B,C
Explanation:
Licensing Requirements: Both the primary and secondary systems must have the same premium
features licensed to ensure compatibility and functionality for asynchronous mirroring.
System Discovery: Both systems need to be discovered by an Enterprise Management Window
(EMW) or SANtricity Unified Manager to facilitate the setup and management of asynchronous
mirroring.
Importance of Matching Features: Ensuring that both systems have the same features licensed avoids
issues with mirroring operations that depend on specific functionalities being available on both ends.
Management Tools: Using EMW or SANtricity Unified Manager helps in configuring, monitoring, and
managing the mirroring process effectively.

A customer wants to manage an E-Series system over a secure connection between the system and a
server. During implementation, you are asked to fulfill this installation requirement.
In this scenario, which three actions are required to complete this task? (Choose three.)
A,C,E
Explanation:
Secure Connection Requirement: To manage the E-Series system over a secure connection, certain
steps need to be taken to ensure encrypted communications.
Disabling Legacy Management Interface: This step ensures that only secure management interfaces
are used, preventing the use of less secure legacy protocols.
Certificate Signing Request (CSR): Completing the CSR on the system is necessary to generate a
public/private key pair. This CSR can then be submitted to a certificate authority (CA) to obtain a
signed certificate.
Importing CA Signed Certificates: Once the CA has signed the certificate, it must be imported into the
E-Series system. This signed certificate ensures that the communication between the server and the
system is encrypted and trusted.

A company has a duplex E-Series system that is operating in a highly tuned environment. Load
distribution between the controllers has been manually set up to achieve a specific distribution
based on unique workload characteristics.
In this scenario, to maintain this load distribution over time, which E-Series feature should be
disabled?
D
Explanation:
Understanding Load Distribution: In a duplex E-Series system, load distribution between controllers
can be manually set up to optimize performance based on specific workload characteristics.
Automatic Load Balancing: This feature automatically redistributes workloads between controllers to
balance the load. However, in a highly tuned environment with manually configured load
distribution, this automatic feature can disrupt the optimized settings.
Disabling Automatic Load Balancing: To maintain the manual load distribution over time, the
Automatic Load Balancing feature should be disabled. This ensures that the workload remains
distributed according to the specific manual configuration without interference from automatic
adjustments.

A company is using the Federal Information Processing Standard (FIPS) on all volume groups.
However, one volume group failed a security audit.
In this scenario what would cause a volume group to fail the security audit?
A
Explanation:
FIPS Compliance: The Federal Information Processing Standard (FIPS) requires all components within
a system to adhere to specific security standards.
FDE Drives: Full Disk Encryption (FDE) drives are used to ensure data security.
Audit Failure: Adding an FDE drive as a spare to a volume group without proper encryption settings
could cause a security audit to fail.
Solution: Ensure all spare drives in a volume group meet the FIPS encryption requirements.

Which two actions must be performed to enable iSCSI multipathing on Windows for NetApp E-Series
systems? (Choose two.)
A,B
Explanation:
iSCSI Multipathing: Enables multiple paths for data to travel between the host and storage, providing
redundancy and increased performance.
Steps to Enable:
iSCSI IP Setup: Configure IP addresses for the iSCSI interfaces on both the E-Series system and the
Windows host to ensure proper network communication.
Host Utilities: Install NetApp E-Series Host Utilities on the Windows host to provide the necessary
drivers and multipathing software.
Reference: NetApp E-Series SANtricity Software and Windows Host Utilities Installation and
Configuration Guide.
A customer is running several EF570 systems and uses the ability of the EF-Series systems to run two
host protocols at the same time. You are installing a new EF570 that uses the NVMe protocol for a
high performance computing application. The controller on-board ports will not connect, but the HIC
ports are working fine.
In this scenario, what is the problem?
C
Explanation:
EF570 Systems: The EF570 supports multiple host protocols simultaneously, including NVMe.
Connection Issue: The controller on-board ports not connecting while HIC ports are working fine
suggests a potential configuration issue.
SFP Mismatch: The most likely cause is that the on-board ports have the wrong Small Form-factor
Pluggable (SFP) modules installed for NVMe protocol.
Solution: Ensure that the correct SFPs for NVMe protocol are installed in the on-board ports.
Reference: NetApp E-Series Hardware Installation Guide, Host Protocol Configuration section.
Which data protection strategy has the most overhead capacity as a percentage of the total capacity?
A
Explanation:
RAID Levels Overview:
RAID 5: Single parity, moderate overhead.
RAID 6: Dual parity, higher overhead than RAID 5.
RAID 10: Mirroring and striping, highest overhead due to 100% redundancy (mirroring).
Dynamic Disk Pools (DDP): Efficient use of capacity but more overhead than RAID 5.
Overhead Calculation:
RAID 10 has the most overhead because it mirrors all data, effectively using twice the storage
capacity.
Capacity Overhead: The overhead in RAID 10 is 50% of the total capacity, meaning if you have 1 TB of
usable storage, you need 2 TB of total storage.
Reference: NetApp E-Series Storage Management Guide, RAID level comparison charts.
An administrator is asked to provision a 1 TB volume to hold non-critical temporary data for a
seismic-analysis application. The volume requires the highest possible IOPS.
In this scenario, which configuration would satisfy this requirement?
C
Explanation:
Understanding the Requirements: The administrator needs to provision a 1 TB volume for non-critical
temporary data that requires the highest possible IOPS.
Non-Critical Data: Since the data is non-critical, redundancy (data protection) is not the primary
concern. Therefore, RAID 0, which does not provide redundancy but maximizes performance, is
suitable.
Highest Possible IOPS: RAID 0 is known for providing the highest IOPS compared to other RAID levels
because it stripes data across multiple disks, allowing simultaneous read/write operations.
Segment Size: A smaller segment size (32 KiB) will result in higher IOPS for small random I/O
operations, which is typical in seismic-analysis applications.

guidelines.
Your company has deployed an E2824 and has decided to change the host protocol from iSCSI to FC.
You use the storage array profile to review the installed SFPs.
In this scenario, which set of supported data rates indicates that you are using dual-purpose SFPs?
B
Explanation:
Dual-purpose SFPs: These are transceivers capable of supporting multiple data rates, allowing for
flexible deployment in different networking environments.
Supported Data Rates: In the scenario where you are reviewing the storage array profile to
determine if dual-purpose SFPs are installed, a set of supported data rates of 32 Gbps, 16 Gbps, 8
Gbps, and 4 Gbps indicates the presence of such SFPs. This enables the switch from iSCSI to FC
without needing to replace the hardware.
Configuration: Once the correct SFPs are identified, the host protocol can be adjusted accordingly
within the SANtricity System Manager to utilize the desired Fibre Channel speeds.
