How many distinct states can be stored by a multi-level SSD cell? Two four eight sixteen ----- Which statements correctly describe the use of SAS edge expanders? (Select two.) Server-attached storage configurations typically use edge expanders. x When an edge expander is incorporated into the architecture, up to 128 segments can exist within a SAS domain. X-- Edge expanders can address up to 128 SAS addresses or drives in a segment. X-- There can only be one edge expander per SAS domain. x Each SAS domain must have one primary and one backup edge expander. Which statements correctly describe the Solid State Drives? (Select three.) Multi-Level Cell (MLC) drives cost less and provide higher storage densities. x-- Single-Level Cell (SLC) drives provide faster write performance and greater reliability x-- MLC technology is based on two bit values per cell—either zero or one. x Four distinct states can be stored in each SLC. x Server storage uses predominantly MLC technology x SSDs connect to the host system using an optimized ESDI communication protocol. X-- What are the two types of expanders used in SAS topologies? (Select two. Core x-- Ring Fan out edge x-- cascaded Which connectivity component combines the functions of the host bus adapters, Ethernet network interface cards, the Fibre Channel over Ethernet protocol, and the Converged Enhanced Ethernet protocol? SDN controller multifunction HBA Fibre Channel switch converged network adapter xX
In which situations is NPIV useful? (Select two.) In virtual server environments, where each virtual server must see only its own SAN-based storage In server blade environments, where the administrator must be able to fine-tune the bandwidth of each server blade adapter port. in server blade environments, where the administrator requires simplified configuration and administration of server-to-SAN connections x-- in redundant SAN environments, where transparent and near-instantaneous path failover is required for business-critical applications x-- in complex SAN configurations, where hard and soft zoning must coexist and fabric segmentation is likely to occur Which HPE networking product delivers NPIV-based Fibre Channel connectivity for server blades? FlexFabric Virtual Switches Virtual Connect (VC) modules FlexNetwork Virtual Services Routers (VSRs) x-- Virtual Application Network (VAN) SDN controllers Which addressing scheme is used by the Fibre Channel switch ports to achieve the 16 million address space 16 x-- 24 32 48 Which fabric zoning approach has the following attributes? ● is the minimum required zoning method ● prevents interaction of the HBAs with incompatible operating systems ● allows multiple HBAs with the same operating system to be grouped with the accessed storage port zoning by HBA zoning by OS xX zoning by application zoning by LUN What happens when two or more switches are joined together by ISLs but they do not communicate with each other zone divergence
per-LUN ACLs device-level ACLs operating system-assisted authorization selective LUN presentation based on the WWN Which risk mitigation measure protects both the confidentiality and integrity of SAN data? full backup site replication x-- auditing encryption Review the diagram shown below. In this diagram, label “A” refers to which data protection goal? Recovery Time Objective (RTO) Recovery Point Objective (RPO) Recovery Time Actual (RTA) X-- Recovery Consistency Objective (RCO) You are implementing HPE 3PAR Remote Copy for data protection and disaster recovery involving two sites separated by a great distance. Using the asynchronous periodic mode, when are the write operations acknowledged to the host? when data is written to the cache of two nodes within the target primary storage array when data is written to the cache of at least one node within the target primary storage array when data is written to a permanent medium of at least one node within the target primary storage array when data is written to the cache of at least one node within the target primary storage array and the cache of the secondary or backup storage x--- When using H-series switches, which topology yields the largest number of user ports? single-switch fabric cascaded fabric -- meshed fabric x ring fabric Review the picture below. Which SAN fabric topology is depicted by this picture? Ring
