Question
Scenario 1:
A large publicity-traded motion picture exhibitor that is a leader In digital and 3D cinema deployments orepates 233 theaters and more than 2,200 screens in small to mid-sized communities in 35 states around 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 7TB 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 dally work. The company currently relies on an aging robotic tape library and a process that takes the nightly backup tapes of site 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 re-run could take p to 10 hours, even if just one job failed. The company has deployed an virtualized server infra structure which runs VmWare VSphere 5 on HP Blade system c7000 enclosures and BL46Oc servers interconnected with HP virtual Connect Flex-10 10Gb Ethernet modules as well as several HP ProLiant DL380 servers. The company top four IT improvements goal 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 thee business benefit goals are as follows:
- increased confidence in disaster recovery
- Minimal disruption by backup 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. Refer to the scenario. Which additional information do you require to validate the customer DR strategy? (Select two.)

Why each option
The scenario describes a company's current backup and disaster recovery strategy involving large data volumes, lengthy backup times, and physical tape transport, which highlights the importance of recovery objectives and data dynamics.
RTO (Recovery Time Objective) and RPO (Recovery Point Objective) are crucial metrics that define the acceptable downtime and data loss respectively, directly impacted by the 72-hour full backup duration and the time required for tape transport to the disaster recovery site. These metrics are fundamental to evaluating the effectiveness of any disaster recovery solution in the given scenario.
Data structure describes how data is organized, which is a technical detail, but not a primary business or operational factor impacting the described backup and DR challenges like RTO/RPO or data change rate.
The data change rate significantly influences the size and frequency of incremental backups and the overall volume of data that needs to be protected, directly impacting the 7TB backup size and the 72-hour backup window described. Understanding how quickly data changes is critical for designing an efficient and timely backup and recovery strategy.
The number of hosts is a factor in infrastructure scaling but is not directly identified in the scenario as a primary challenge or consideration regarding the 7TB data volume, 72-hour backup, or tape transport.
While the 150-mile distance between data centers is mentioned and impacts tape transport time, RTO and RPO encapsulate the business impact of this distance, making A a more comprehensive and directly relevant answer to the overall DR strategy.
