When sizing a solution involving deduplication, how does the rate of changed blocks between backups affect the deduplication ratio?

• A. The rate of changed blocks does not affect deduplication efficiency.
• B. Deduplication ratio is only affected by the backup software.
• C. The lower the block change rate, the higher the deduplication ratio.
• D. No changed blocks between backups result in a deduplication ratio of 0%.

A company with a first-generation deduplication appliance is migrating to an HP StoreOnce 6200 Backup System. After migration, what will be the size of the deduplication block?

• A. 32 kb
• B. 4 kb
• C. 8 kb
• D. 16 kb

Refer to the scenario.
A large publicly-traded motion picture exhibitor that is a leader in digital and 3D cinema deployments operates 233 theaters and more than 2,200 screens in small to mid-sized communities in 35 states around the United States. They rely on MS Exchange Server 2010 for email. MS SQL Server 2010 for analyzing data about movies and theater-goers, and MS Excel 2010 for crunching numbers.
The company runs nightly incremental backups and a full weekly backup that consists of close to 7 TB of data which takes up 72 hours to complete. The quarterly backups add an additional 7 TB of data. Tapes are inventoried and transported from the main data center to the disaster recovery site 150 miles away. The process of transporting tape cartridges to and from the Disaster Recovery site requires hours of daily work.
The company currently relies on an aging robotic tape library and a process that takes the nightly backup tapes offsite every morning. Additionally, the company keeps an inventory, and if a restore is necessary they have to retrieve the tapes from the DR site and transport them to the main data center site They have a 7 year data retention plan, and the tapes are expensive and not always reliable. Given the company's current system, if a full weekly backup fails over a weekend, the rerun could take up to 10 hours, even if just one job failed.
The company has deployed a virtualized server infrastructure which runs VMware vSphere 5 on HP BladeSystem c7000 enclosures and BL460c servers interconnected with HP Virtual Connect Flex-10 10Gb Ethernet Modules as well as several HP ProLiant DL380 servers.
The company's top four IT improvements goals are as follows:
-replacing the aging robotic tape library
-enabling replication of backed up data from the main data center to the disaster recovery site (150 miles)
-retaining more backup data in smaller disk space
-increasing efficiency reliability, and ease of system administration Moreover the company's top three business benefit goals are as follows:
-increased confidence in disaster recovery
-minimal disruption by backups during regular business hours
-improved management of external audits
The company has asked that you create multiple solution proposals and prioritize one when you return for a presentation.
During a design workshop, you become aware that the customer is adding a number of application servers into the virtualized environment to be included in the backup environment. What is the minimum number of stores you need to create in order to achieve optimal deduplication performance?

• A. 3
• B. 8
• C. 1
• D. 4

Refer to the scenario.
A university provides liberal arts training to 2,500 students in 68 classrooms and provides a growing suite of IT services that encompass dorm rooms and classrooms. All 2,500 students are provisioned an HP EliteBook Tablet PC to access these services. Students use these tablet PCs for taking notes, handling documents, communicating with each other and with instructors, and participating in distance-education classes.
Additionally, by using their tablet PCs as thin clients, science and engineering students leverage virtual desktop infrastructure (VDI) and HP Remote Graphics Software to access applications that run on high-powered HP blade servers. All 68 classrooms are multi-media equipped, enabling instructors to record lectures for the college s closed circuit TV system.
The university has implemented enterprise content management (ECM) applications, including Microsoft SharePoint for document imaging and workflow for staff and faculty, as well as for external accrediting bodies.
Additionally, a recent initiative to implement voice-over-IP telephone communications on campus has started.
The compute environment is based on VMware vSphere using HP BL460c and BL680c G7 server blades in c7000 enclosures within two data centers.
The university needs to develop computing solutions to address the following problems and current initiatives:
-The current backup-to-tape environment creates downtime for backups of 6 to 12 hours.
-Each incoming class of 600 floods the registration system within the first hours after it opens. The server and network gridlock caused by this high workload prolongs the registration process by as much as one hour per student.
-Proof of concept is necessary for distance education involving large volumes of video and major bandwidth requirements.
-Top tier data must be replicated between two data centers over a 10 Gbps network Disaster recovery has a recovery time objective (RTO) of 120 minutes and network utilization should be minimized.
-Seven TB of first tier data needs to be migrated from the current fibre channel storage solution to nearline storage.
-Second tier data requires deployment of a separate storage solution. The university's top four IT improvements goals are as follows:
-Provide a robust replication capability between data centers.
-Reduce server downtime with faster backups.
-Retain more backup data in smaller disk space.
-Increase efficiency, reliability, and ease of system administration. Moreover the college's top three business benefit goals are as follows:
-Reduce student registration time.
-Increase number of servers while minimizing the need for additional staff to support them.
-Utilize IT resources and staff as efficiently as possible.
