HP Architecting Multi-site HP Storage Solutions Sample Questions:

1. Your customer asks you to assist in designing a new cost effective storage solution. The solution will be used to store archive data. It must be able to replicate point-in-time copy of data at the primary site to a remote site.
The solution must provide block-level access and support Fibre Channel. There is very little rack space available at the primary site.
Which solution meets the customer requirements?

A) HP Storevirtual
B) HP MSA
C) HP EVA
D) HP 3PAR StoreServ

2. 2 DataCenters, FC network was grown -> more than 200 ports per Fabric, FC Switches 8-40 ports, Each in dual redundant layout.
The Goals are:
A) Customer should consolidate to latest technology
B) FC Connection between DC needs to be encrypted, scale beyond 300 ports, with least Management

A) HP SN8000C Director
B) HP DC SAN Director
C) HP SN 9500C Director
D) HP SN8000B SAN Director

3. Refer to the scenario. Items to

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 Flex10 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 follow-up meeting with your customer, you learn that there is an additional business requirement to limit the total downtime of data center systems to 72 hours, and no more than 24 hours of data can be lost. The IT department indicates that they have an existing 2-hour response time SLA with their business users for critical systems.
What should you use for their RTO and RPO when designing a new backup solution?

A) RTO - 72
B) RPO - 24

4. You are designing a storage solution for a customer who has three data centers on a campus and a 10Gb/s network infrastructure. The business requirements state that a complete site failure must be tolerated. You propose six HP Storevirtual 4530 nodes split evenly between the sites.
Which Network RAID level should you recommend to the customer to meet their business availability needs?

A) Network RAID 6
B) Network RAID 10+1
C) Network RAID 10+2
D) Network RAID 5

5. You are tuning a customer HP StoreOnce Backup System and notice they are running backups 20 hours a day. As a result, backup jobs are running during the same time as replication jobs. What can you do to limit the available bandwidth and not saturate the link with replication traffic?

A) Map multiple source libraries into a single target library.
B) Enable concurrency control.
C) Enable multiplexing and set concurrency to 1.
D) Enable compression.
