NEW QUESTION # 21
If the erasure coding technique used divides data into 12 data segments and 5 coding segments, what is the maximum number of disk drive failures against which data is protected by the configuration?
- A. 0
- B. 1
- C. 2
- D. 3
Answer: A
Explanation:
Erasure coding is a method of data protection in which data is divided into data and coding segments. In this case, the configuration has 12 data segments and 5 coding segments, allowing it to tolerate up to 5 simultaneous disk failures. The coding segments provide redundancy, enabling the reconstruction of data even if up to 5 disks fail.

What type of network connectivity is illustrated in the image below?
- A. Storage to hybrid cloud connectivity
- B. Compute to storage connectivity
- C. Compute to hybrid cloud connectivity
- D. Data center to data center connectivity
Answer: B
Explanation:

NEW QUESTION # 24
A Fibre Channel switch has eight ports and all ports must be operational from 6 AM to 6 PM, Monday through Friday.
However, a failure of Port 4 occurs with the week as follows:
Monday= 11 AM to 1 PM
Wednesday= 5 PM to 10 PM
Thursday= 7 AM to 10 AM
Saturday= 11 AM to 1 PM
What is the availability of Port 4 in that week?
- A. 86.7%
- B. 81 6%
- C. 90%
- D. 80%
Answer: A
Explanation:
To calculate availability, you need to calculate the total number of hours that the port is operational and divide it by the total number of hours in the week, which is 168. The total number of hours that Port 4 is operational in that week is 106.7, so the availability is 106.7/168 = 86.7%.
NEW QUESTION # 25
Which FCIP protocol stack layer supports FC frame encapsulation?
- A. TCP
- B. IP
- C. UDP
- D. FCP
Answer: A
Explanation:
The FCIP (Fibre Channel over IP) protocol stack uses TCP (Transmission Control Protocol) to encapsulate Fibre Channel frames for transmission over IP networks. TCP provides a reliable, connection-oriented transport layer that ensures the ordered delivery of data, making it suitable for encapsulating the FC frames and transporting them across IP networks. This enables the extension of Fibre Channel networks over long distances using existing IP infrastructure.References:

NEW QUESTION # 26
What occurs when a company's IT infrastructure security is breached by a passive attack?
- A. unauthorized system access is obtained
- B. data is altered by an unauthorized user
- C. access to services is denied
- D. availability of data is affected
Answer: A
Explanation:
A passive attack in IT security involves unauthorized monitoring and gaining access to data without altering it.
This type of attack is often used for data gathering and eavesdropping, where the attacker gains access to sensitive information without modifying or disrupting the system's operations.

NEW QUESTION # 27
What accurately describes an object-based storage device (OSD)?
- A. Objects are created based on the name and location of the file
- B. Numerous objects can be stored in a single namespace
- C. One object can be placed inside another object
- D. Objects exist at the same level in the address space
Answer: D
Explanation:
* Object-Based Storage Device (OSD): OSDs manage data as objects, which contain the data itself, metadata, and a globally unique identifier.
* Address Space: In object storage, all objects exist at the same level in a flat address space, meaning there is no hierarchical structure like in traditional file systems.
* Namespace: Object storage systems use a single namespace to manage objects, making it easier to scale and manage large amounts of data.

NEW QUESTION # 28
What is an accurate statement about scale-out NAS?
- A. Pools node resources in a cluster to work as multiple NAS devices
- B. Supports only data replication for protecting data
- C. Creates a different file system for each node in the cluster
- D. Stripes data across nodes with mirror or parity protection
Answer: D
NEW QUESTION # 29
Which is a characteristic of RAID 6?
- A. Double parity
- B. All parity stored on a single disk
- C. Single parity
- D. Parity not used
Answer: A
Explanation:
RAID 6 is characterized by double parity, which means that it uses two parity blocks to protect against data loss. This double parity allows RAID 6 to tolerate the failure of two drives within the RAID array, making it more reliable than RAID 5, which only uses single parity.

NEW QUESTION # 30
What is the functionality of the lock in a cyber recovery process?
- A. Determines if a replication copy contains malware or other anomalies
- B. Synchronizes the latest data and creates restore points
- C. Isolates network and prevent network from establishing an external connection
- D. Restricts overwriting of data to meet both corporate governance and compliance standards
Answer: D
Explanation:
The lock functionality in a cyber recovery process is primarily designed to restrict the overwriting of data to meet both corporate governance and compliance standards. This is crucial for ensuring the integrity and availability of data in the event of a cyber incident. The lock prevents unauthorized changes to the data, ensuring that the recovery point remains pristine and reliable for restoration purposes. This functionality is vital for meeting compliance requirements, which often mandate that data be protected from unauthorized alteration.

NEW QUESTION # 31
What is a benefit of migrating to a modern data center?
- A. Reduce public cloud application development complexity
- B. Reduce the cost of managing data center components by using a self-service catalog
- C. Reduce management complexity by deploying only unified and converged IT resources
- D. Reduce administration complexity and application downtime to consistently meet SLAs
Answer: C
NEW QUESTION # 32
Which intelligent storage system component performs replication and storage management functions?

NEW QUESTION # 33
Which components should be used for interconnecting hosts to storage systems in FC SANs?
- A. FC switches
FC hubs
FC N_Ports - B. FC switches
FC directos
FC E_Ports - C. FC directors
FC hubs
FC FL_Ports - D. FC switches
FC directors
FC FE_Ports
Answer: B
Explanation:
FC SANs components include network adapters, cables, and interconnecting devices. The interconnecting devices can be FC switches or FC directors, which are more scalable and reliable than FC hubs. The ports on these devices can be FC E_Ports, which connect two switches or directors together to form a fabric, or FC F_Ports, which connect to host or storage devices with FC N_Ports.

NEW QUESTION # 36
An organization wants to protect data from accidental deletion, application crashes, data corruption, and disaster.
Which solution should the organization adopt?
- A. Storage tiering
- B. Data backup
- C. Thin provisioning
- D. Data archiving
Answer: B
Explanation:
Data backup is the process of copying data to a secondary location to protect it from accidental deletion, application crashes, data corruption, and disasters. Regular backups ensure that data can be restored to a previous state in case of any data loss events.

NEW QUESTION # 38
Which statement is true regarding virtual provisioning?
- A. Virtual provisioning prevents issues that arise from oversubscription
- B. Multiple shared storage pools can be created while each pool must be allocated to a unique thin LUN
- C. Shared and Thin LUNS can be expanded rapidly with only minor disruptions
- D. Virtual provisioning enables more efficient allocation of storage to compute systems
Answer: D
Explanation:
Virtual provisioning is a storage management technique that enables more efficient allocation of storage to compute systems. It allows storage administrators to create virtual storage resources that are presented to compute systems as if they were physical resources, even if the physical storage capacity does not exist.
Virtual provisioning supports various types of virtual storage, including thin LUNs and thin clones. Thin LUNs enable shared and rapid expansion with only minor disruptions. Multiple shared storage pools can be created, and each pool can be allocated to multiple thin LUNs. However, virtual provisioning does not prevent issues that arise from oversubscription; it is important to monitor and manage capacity utilization to avoid performance degradation or service disruptions. Reference: Section 2.5.1 Virtual Provisioning, page 107.
