A customer wants to use 2 Gbps B-series (Brocade) fabric switches in an extended fabric configuration with two 35 km single-mode fiber optic ISLs. What is required for the two switches on either end of the link?
A. An extended fabric license must be added to all switches in the SAN.
B. A remote switch license must be added to both switches.
C. Nothing is required, simply connect the ISLs.
D. An extended fabric license must be added to both switches.
A customer is testing storage array replication with two storage systems in their data center. The arrays are connected with fiber optic cables that are a total of 30 meters in length. The replication mode is changed from synchronous to asynchronous. How does this affect replication performance in this case?
A. Asynchronous mode replication is much faster than synchronous mode.
B. Synchronous mode replication is slightly faster than asynchronous mode
C. Synchronous mode replication is much faster than asynchronous mode.
D. Asynchronous mode replication is about the same as synchronous mode.
What are three types of backup topologies? (Choose three.)
A. WAN backup
B. MAN backup
C. local backup
D. SAN backup
E. LAN backup
What is a design property of the Core+Edge+Leaf SAN topology?
A. It allows many devices to share a single ISL.
B. It provides a reasonable bandwidth guarantee to nodes connected to a first- or second-level edge switch.
C. It allows for placingtrunking-capable switches adjacent to each other.
D. It involves simplex I/O, meaning only one path is utilized for I/O.
What happens in the Storage Assessment phase of the SAN architecture approach? (Choose three.)
A. selection and establishment of guidelines models, principles, and standards for the SAN
B. description of the feasibility of an effective solution based on obstacles and constraints
C. an inventory of systems, software, employee skills, and internal processes/documentation
D. analysis and documentation of business requirements, organization, physical environment, networks, and infrastructure management
E. Business data is classified, utilization of data is explored, ownership and usage statistics of application volumes on systems are reported.
What is a best practice for large scale SANs and SAN scaling?
A. implement bandwidth and throughput with support for a cascaded SAN topology
B. implement enough bandwidth and throughput to support the business requirements
C. implement enough bandwidth and throughput to support twice the business growth
D. implement adequate bandwidth and throughput with support for business driven growth over time
You are replicating data over long distances using 1 Gbps B-series (Brocade) fabric switches. Extended fabrics (increased buffer-to-buffer credits) should be used when the minimum distance exceeds _____ km.
A. 15
B. 35
C. 10
D. 20
In IP networks, which two best practices should site planning include? (Choose two.)
A. use only one controller pair per FCIP link to avoid link congestion
B. minimize the amount data transferred over the FCIP link(s)
C. create a design that will accommodate additional storage I/O without impacting normal data traffic
D. merge the FCIP network with your corporate network for better management
A SAN administrator plans to implement fabric wide storage virtualization. The current SAN consists of dual redundant ring topology. Without detailed information about the virtualization, what topology should they plan to migrate to?
A. cascaded topology
B. tree topology
C. meshed topology
D. no change ring topology
