Question 1

Which two statements about jumbo Ethernet frames are correct? (Choose two.)
A) A jumbo frame is an Ethernet frame with a payload greater than 1500 bytes.
B) Jumbo frames are always a fixed standard length of 9000 bytes.
C) Jumbo frames can increase the latency on a network due to the transmission of larger frames.
D) Jumbo frames enable the transmission of iSCSI packets on the IP network.

Accepted Answer

Many networks use 1500-byte MTU size, but the MTU size can be reduced by encapsulation, tunneling or other overlay network protocols. These situations reduce the end-to-end effective MTU size which reduces throughput and network efficiency and sometimes causes application problems. Many network devices now support larger sizes of Ethernet frames and use of Jumbo Frames is becoming more common. This article covers how to determine if your network is capable of using Jumbo Frames and if you should enable this feature.

Question 2

According to SNIA, what are two valid storage tiering types? (Choose two.)
A) storage cache tiering
B) host tiering
C) application tiering
D) cloud tiering

Accepted Answer

D  Storage cache tiering and cloud tiering are recognized by SNIA as valid types of storage tiering, which involve managing data across different storage media or locations to optimize performance and cost.

Question 3

You want to replace multiple copies of data, at variable levels of granularity, with references to a shared copy to save storage space and/or bandwidth. Which data reduction method would satisfy the requirement?
A) deduplication
B) compression
C) thin provisioning
D) conditioning

Accepted Answer

Deduplication is a data reduction method that eliminates duplicate copies of repeating data, replacing them with references to a single shared copy, thus saving storage space and bandwidth.

Question 4

A) The customer has a zero data loss requirement.
B) The customer has no data at risk.
C) The customer has a zero tolerance policy.
D) The customer has a zero chance of failure.

Question 5

At which level would you apply LUN masking?
A) file system level
B) switch level
C) zone alias level
D) controller level

Accepted Answer

LUN masking is applied at the controller level to restrict access to specific LUNs for certain hosts, ensuring that only authorized systems can access the storage resources.

Question 6

What are two requirements of a server cluster with regards to storage technologies? (Choose two.)
A) a switch fabric
B) a file locking mechanism
C) a back-end storage database
D) shared storage

Accepted Answer

Shared storage and a switch fabric are two requirements of a server cluster with regards to storage technologies. Shared storage allows multiple servers to access the same data, while a switch fabric provides high-speed connectivity between the servers and the storage devices.

Question 7

What would be placed in a Fibre Channel zone?
A) IP address
B) MAC address
C) IQN of an initiator
D) World Wide Port Name (WWPN)

Accepted Answer

Fibre Channel zoning uses World Wide Port Names (WWPN) to control access to storage devices within a SAN.

Question 8

What is another name for a storage volume?
A) Converged Network Adapter (CNA)
B) logical unit number (LUN)
C) storage port
D) Host Bus Adapter (HBA)

Accepted Answer

LUN is a logical unit storage used to identify a device addressed by the SCSI protocol or storage area network protocols which encapsulate SCSI such as Fibre Chanel or iSCSI, etc.

Question 9

Which storage technology uses optics for connectivity?
A) LTO tape
B) SAS
C) SATA
D) Fibre Channel
E) iSCSI

Accepted Answer

Fibre Channel uses optical fiber cables for high-speed data transfer, making it an optical connectivity technology.

Question 10

What are two reasons for using a full backup? (Choose two.)
A) When a host needs to have all of the data available to be restored.
B) When a host restore can be accomplished across multiple jobs and sessions.
C) When a backup requires minimal space consumption.
D) When a backup must be available in one backup image.

Accepted Answer

A full backup is a backup of all the data on a host. It is used when a host needs to have all of the data available to be restored, or when a backup must be available in one backup image.

Question 11

What are two scenarios where using disk replication is a valid risk mitigation strategy? (Choose two.)
A) a primary storage array non-recoverable hardware failure
B) an extended power failure at the primary site
C) information destruction due to a security breach
D) system instability due to a bad OS update

Accepted Answer

Disk replication is a valid risk mitigation strategy for a primary storage array non-recoverable hardware failure and an extended power failure at the primary site because it provides a redundant copy of the data on a separate disk array. In the event of a failure of the primary storage array, the data can be recovered from the replicated disk array.

Question 12

What is an implementation of a secure, multi-tenant cloud environment that is externally available to all users?
A) private
B) public
C) secure
D) hybrid

Accepted Answer

A public cloud environment is externally available to all users.

Question 13

You explain to a customer that storage data compression can be used on most data types. However, there are exceptions. Which file type is an exception?
A) *. txt
B) *. bat
C) * . J pg
D) *. ora

Accepted Answer

The answer of You explain to a customer that storage...

Question 14

Which two technologies use NAND flash memory (non-volatile) technology to store data? (Choose two.)
A) quad-level cell (QLC)
B) single-level cell (SLC)
C) interim-level cell (ILC)
D) multi-level cell (MLC)

Accepted Answer

The answer of Which two technologies use NAND flash memory...

Question 15

What do RAID 5 sets use to rebuild data?
A) Flash memory
B) mirroring
C) parity
D) data quiescing

Accepted Answer

Post-failure replacement takes place when the hard drive breaks unexpectedly before a pre-failure replacement can take place. The data on the failed drive must be rebuilt from the parity data on the remaining active drives and written to a hot spare. Post-failure replacement takes considerably longer due to the calculations that must take place to rebuild the data.

Question 16

Your customer has a Fibre Channel SAN environment and has properly zoned servers for storage with front end controller ports. When an administrator goes to initialize a provisioned volume, it is not seen on the server. What would cause this problem?
A) an unplugged cable
B) a multi-path I/O failure
C) a corrupted volume
D) improper LUN masking

Accepted Answer

The answer of Your customer has a Fibre Channel SAN...

Question 17

What is the function of the Fibre Channel name server?
A) It retrieves all files from a file store by name.
B) It provides service to register Fibre Channel N_Ports.
C) It partitions Logical Unit Numbers (LUNs).
D) It load balances the SAN traffic.

Accepted Answer

The Fibre Channel Name Server provides a way for N_Ports and NL_Ports to register and discover Fibre Channel attributes.  Such attributes include names, addresses, types, features, etc., at various protocol layers, including upper layer protocols specific to Fibre Channel (which are sometimes called "FC-4s").  Communication with the Name Server is via Fibre Channel's CT (Common Transport for Generic Services) using "Information Units" (called CT_IUs) as either requests, responses, or unsolicited.

Question 18

What should a valid iSCSI qualified name include?
A) the iSCSI string
B) date code, in yyyy-mm format
C) the WWN string
D) initials of company name

Accepted Answer

Question 19

Which statement describes an N_Port login?
A) a process by which a server HBA port logs in to a fabric
B) a process by which FC initiators establish sessions with targets
C) a process by which users obtain access to a host
D) a process by which two FC-4 layer processes establish communication

Accepted Answer

An N_Port login is a process by which Fibre Channel (FC) initiators establish sessions with targets, allowing communication between devices in a storage area network.

Question 20

Which software technique reduces the effects of a hardware component failure?
A) volume management
B) multi-pathing
C) LUN masking
D) zoning

Accepted Answer

Multi-pathing provides multiple physical paths to the storage, ensuring that if one path fails, another can be used, thus reducing the effects of hardware component failure.
