Answer : A Topic 17, Scenario 30 Refer to the Exhibit.

An investment bank has 1,000 employees in three regional offices. The bank wants to expand operations and grow its customer base and product offerings. To meet the anticipated demand of its expanded customer base, the bank needs an updated Fibre Channel SAN infrastructure. The SAN will support all of its operations, including file servers, accounting applications, web servers, and home banking applications. ? Enterprise reliability ? High performance ? Seamless scalability ? Flexibility ? Security ? Minimized installation costs ? Reduced maintenance costs There are multiple challenges for this project. It must support planned growth, an optimized infrastructure, centralized management and data access, and maintain 99.999% availability. Finally, it must comply with governmental regulations. The bank has invested heavily in the RSA Data Loss Prevention (DLP) Suite and Data Protection Management (DPM) for its PCI security and compliance needs. ROI and TCO are critical to the acceptance of the proposal. The solution must provide capacity to accommodate at least 20% growth per year without requiring additional hardware for 3 years.

Answer : A Topic 18, Scenario 28 Refer to the Exhibit.

A telecommunications company has implemented a disaster recovery solution for their data center using RecoverPoint. The company has installed two RPAs in each site and configured CLR for file server storage and CRR for their Microsoft Exchange systems. All hosts are running Microsoft Windows Server 2003; however, they are migrating to Microsoft Windows Server 2008 over the next six months. The customer will also be consolidating some of these servers to VMware virtual machines as part of their upgrade process. The storage arrays are all CLARiiON CX4 systems. The SANs use B-Series switches for connectivity configured in a mirrored, full-mesh fabric. The company implemented the KDriver splitter at all sites to limit the splitting and traffic to the host level. The disaster recovery site is located 25 km away from the production site. A leased dark fiber line, running at 1 Gb/s, was put in place to handle the replication traffic. Additional WAN links exist for intersite communications and management. To support the actual replication needs, 70 consistency groups were created, pushing 100 MB/s throughput. The policy for these consistency groups was set to an RPO of 2 hours and the company would like to operationally recover with an RTO of 3 hours.

The company will be adding new virtual machines associated with the replicated datastores and is concerned that adding new virtual machines will affect the current performance load of their RPA replication cycles.
How would you address this concern before the VMware servers are brought online?

  • A. Add RPAs to the cluster at each site and balance the load across the consistency groups
  • B. Add RPAs to the source site and balance the load across the consistency groups
  • C. Add a redundant WAN link to the replication infrastructure
  • D. Lay out all of the current consistency groups as distributed consistency groups across the existing RPAs

Answer : A

The company plans to consolidate 30 of the physical servers to virtual machines running on several large datastores, but is concerned with how to protect them for DR.
What should you suggest as the optimal solution?

  • A. Implement SRM to protect the virtual machines and provide for DR with RecoverPoint
  • B. Implement host splitters for Windows Server 2008 on the virtual machines to provide for DR with RecoverPoint
  • C. Protect the virtual machines with VMware HA across the sites to provide for DR with RecoverPoint
  • D. Use VMware storage vMotion across the sites to provide for DR

Answer : A

The company is concerned about the level of availability of the existing replication environment. What should the company do to minimize cost and improve availability?

  • A. Add an RPA to each site to handle consistency group failover for all replicating consistency groups
  • B. Migrate the SAN to MDS directors to support online upgrades of the connectivity layer
  • C. Purchase an additional dark fiber connection and configure WAN redundancy for the replication paths in case of link failure
  • D. Migrate the existing CLARiiON arrays to new Symmetrix VMAX arrays for a back-end refresh

Answer : A

The company is concerned about the server maintenance overhead expenses due to the splitters when performing RecoverPoint upgrades. What should the company do to reduce maintenance costs?

  • A. Migrate the splitters to CLARiiON splitters to consolidate splitting to the storage arrays for replication
  • B. Use the existing splitter drivers on the hosts and upgrade their host splitter protocol to Windows Server 2008
  • C. Migrate the splitters to the Brocade SAN splitters and consolidate splitting to the fabric
  • D. Use a combination of SAN and CLARiiON splitters to balance the splitter operations in the RecoverPoint implementation

Answer : A

The company wants to reduce the total cost of ownership of the replication environment.
Which option should you suggest as the most efficient use of the IT budget to address this concern?
A. Consolidate the SAN switches into a single high-performance director for each fabric at each site
B. Migrate the CLARiiON storage to several Symmetrix VMAX SE storage systems
C. Add Brocade 7600s to the existing fabrics and use FAP splitters instead of host splitters
D. Increase the WAN bandwidth between the sites to a full 4 Gb link

Answer : A Topic 19, Scenario 49 A customer currently stores the data of three critical applications on non-EMC arrays and wants to migrate to Symmetrix VMAX arrays and implement a DR solution with the ? Zero RPO in the case of a production site failure ? Five-minute RPO in the case of a regional disaster ? Production at an out-of-region site (1,000 km away) in case of a regional disaster ? Use of the customer’s lights-out regional data center site (within 200 km of the production site) ? Minimal RTO

The customer is researching options for decreasing overhead at their bunker site facility by using less personnel and hardware. However, the original protection requirements must be kept in place with lower costs.
How can they accomplish both of these requirements?

  • A. Implement SRDF/EDP with Star solution for remote replication
  • B. Implement SRDF/AR for regional protection for remote replication
  • C. Implement concurrent SRDF/Star with SATA drives at the target for remote replication
  • D. Implement a combination of SRDF/S with TimeFinder for remote replication

Answer : A

Which type of device should exist on the Symmetrix array at the out-of-region site after fully implementing SRDF/Star?

  • A. R1
  • B. R11
  • C. R21
  • D. R22

Answer : D

The customer currently has concurrent SRDF/Star in place. They suffered an outage and had to bring the workload site up at site B. They now want to convert from a concurrent
Star setup to a cascaded Star setup.
What must be reconfigured to achieve this?

  • A. Perform an R1/R2 swap between the devices at Site A and Site B
  • B. Switch the workload site to the secondary Site A and Star will automatically be cascaded
  • C. Delete the SRDF pairs across all three sites and set up new SRDF pairings between Site A and Site C
  • D. Switch the workload site to Site C and the resulting action will automatically set up reverse replication in a cascaded Star setup

Answer : A

Why would you recommend SRDF/Star as a possible solution for this customer's requirements?
A. Incremental resynchronization of data between surviving sites when the production site fails
B. Zero RPO at the out-of-region site after a regional disaster
C. Zero RPO at the out-of-region site after a rolling disaster (regional remote site failure followed by production site failure)
D. Zero RPO at the surviving remote site in case of any remote site failure

Answer : A Topic 20, Scenario 55 Refer to the Exhibit.

The customer has asked you to provide a three-year TCO analysis, comparing two solutions. Various cost elements associated with the solutions are provided in the exhibit. All operating costs are annual amounts.
