Study Notes

Question Results Summary

Image-based Backup Advantage: Backup performance improves with agents running on virtual machines, eliminating proxy servers and deduplication needs. Backup processing is offloaded from the production virtual machine.
Virtual Tape Library Statement: Regular maintenance tasks are required for physical tape drives. Legacy backup software often doesn't require additional modules or changes, but only sequential data access for backup and recovery is usually supported. Portability of physical tapes to offsite locations isn't guaranteed.
Component 1 Failure Time: The mean time between failures for Component 1 during the week was 37 hours.
Infrastructure Discovery Statement: Infrastructure discovery creates an inventory of infrastructure components, provides information, and assesses risks. It also classifies, organizes, and analyzes all infrastructure management best practices. Infrastructure discovery can also detect potential storage infrastructure security attacks and deploy tools to eliminate them.
FCoE Environment Statement: FC Forwarder splits FC frames into FCoE frames based on Ethertype. FCoE controllers send RSCNs to all nodes to provide access control. FCoE ASIC encapsulates FCoE frames into FC frames. FCoE networks must be configured to support jumbo frames for optimal performance.
Storage Infrastructure Availability Monitoring: Monitoring storage infrastructure availability evaluates component utilization, detects potential failures leading to unavailability, tracks unauthorized access, and ensures adequate resources to prevent service interruptions.
Dell EMC Product: RecoverPoint enables continuous protection for any PIT recovery and offers multi-site support.
Hypervisor-Based CDP: Write splitter is embedded in the hypervisor. The journal and replicas use the same storage volume. A virtual appliance runs on a storage system.
CDP Solution Recovery Points: The amount of space configured for the journal determines the limit of past recovery points in a CDP solution.
Cloud Computing Characteristic: Resource pooling enables multi-tenancy and obscures the location of resources.
Converged Network Adapter: Physical adapters can provide functionality of both a standard NIC and an FC HBA in a single device.
Object-Based Storage Elements: Metadata, object ID, attributes, file path, and Object ID, data, and attributes are characteristics associated with an object.
LUN Masking Management: Security Management configures LUN masking to restrict host access to specific LUNs within a data centre environment.
Business Continuity Planning: The analyzing stage of business continuity planning involves identifying critical business processes and assigning recovery priorities.
Defense-in-Depth Strategy: Defense-in-depth is a benefit of data center security strategy which enhances and improves security.
Source-Based Deduplication Benefit: Backup data can be retained longer; unique data is sent over the network to be backed up. Backup processing is offloaded from the backup client, resulting in less backup data stored on the backup server.
Link Aggregation in FC SAN: Network traffic is distributed across ISLs, ensuring even ISL utilization. Higher throughput results from combining two parallel ISLs into one physical ISL. Bandwidth is saved by restricting traffic to specific potentially congested ISLs. ISL utilization improves by increasing network traffic on specific ISLs.
Data Protection Type: Archive data to lower cost storage and to improve compliance requirements.
RAID 6 Characteristic: All parity is stored on a single disk.
Cyberattack Type: A phishing attack involves sending a spoofing e-mail to redirect a user to a false website.
RAID 5 Stripe Size: Stripe size is 120KB for a 5-disk RAID 5 group with a 32KB stripe size.
Storage System Data Integrity Features: Deduplication and checksums are essential for data integrity in storage systems.
Fibre Channel Port Availability: Availability of Port 8 throughout the week is 92.8%.
iSCSI Initiator Target Discovery: iSCSI initiators query iSNS servers for lists of available targets.
iSCSI Address Components: IP address, TCP port number, and iSCSI name are components of an iSCSI address.
Intrusion Detection System Technique: Signature-based techniques in an IDPS scan and analyze intrusion events using a database that contains known attack patterns.
Backup Type Advantage: Incremental backups compared to cumulative backups significantly reduce the backup window to almost zero.
Write Operation on SSDs: Requested pages are written into available empty pages within an SSD.
EMC RecoverPoint Product: The EMC RecoverPoint product enables data restoration, data storage in object-based form, and source-based deduplication.
Software-Defined Storage Platform: VIPR Controller abstracts, pools, and automates data center's physical storage infrastructure.
IP SAN Block Type: Storage block I/O data is transported over a LAN in an IP SAN.
Cloud Service: VMware vCloud Air provides Infrastructure as a Service.
Software-Based Object Storage Implementation Advantage: Software-based object storage is flexible enough to reuse existing infrastructure, requiring less storage capacity to store many objects, while allowing the creation of multiple object IDs for one object.
File-Level Storage Tiering Technique for Data Movement: Archiving is a file-level storage tiering technique used to perform policy-based data movement.
Intrusion Detection Method: Anomaly-based methods in an intrusion detection system analyze events to identify differences from normal events. This is done via scanning and analyzing.
Cloud Model for Self-Service Portal: A Software as a Service cloud model allows organizations to consume compute, network, and storage resources through a self-service portal.
