D.

Dynamic Disk Pools (DDP)

Answers
Suggested answer: 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.

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?

A.

The on-board host ports are disabled

A.

Answers
D.

The switch ports are shut-down

D.

The switch ports are shut-down

Answers
Suggested answer: 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.

D.

Install a Host Channel Adapter (HCA) on the Windows host

Answers
Suggested answer: 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.

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.

An FDE drive was added as a spare in the volume group

A.

Answers
D.

Connectivity to the key server was interrupted

D.

Connectivity to the key server was interrupted

Answers
Suggested answer: 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.

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?

A.

Storage Load Balancer

D.

D.

Automatic Load Balancing

Answers
Suggested answer: 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.

Answers
E.

Complete the certificate signing request on the system

E.

Complete the certificate signing request on the system

Answers
Suggested answer: 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.
