What are three key benefits of Cisco’s collapsed-core switch configuration? (Choose three.)
A. higher effective port count
B. ease of management
C. reduction in equipment and installation cost
D. reduction in total disk space requirements
E. increased port channel utilization
In the design of an iSCSI implementation in conjunction with a Cisco MDS-based SAN, which
technology provides for diverse connections into multiple SAN switches and is used to provide
automatic failover using a single target IP address?
What are three key benefits of implementing a SAN using iSCSI? (Choose three.)
A. significant capital cost reduction by substitutingiSCSI as a transport technology
B. uses existing IP networking, monitoring, and management infrastructure
C. maintains consistent performance over IP networks of varying distances
D. is more efficient than FC since it requires fewer encapsulations
E. extends existing FC SAN to IP connected hosts
What are two reasons that remote backup (remote vaulting) is a core application of FCIP?
A. FCIP is very reliable because it always uses host-based synchronous replication.
B. FCIP is very reliable because it always uses disk-based asynchronous replication.
C. Applications are often sensitive to high latency, but in a properly designed FCIP backup
implementation, the application can be protected from problems with the backup process by using
techniques such as snapshots and split mirrors.
D. FCIP is relatively inexpensive when compared with optical storage networking.
E. Enterprises and storage service providers (SSPs) can provide remote-vaulting services by
using existing FCIP WAN infrastructures.
A customer is designing a SAN for each of two data centers. The two data centers are connected
by dark fiber, which is owned by the customer. Cisco ONS platforms terminate the fiber and
provide service aggregation. The customer requirements include that the SAN in each data center
meet or exceed five nines of availability and be interconnected using 16 separate lambdas. The
customer has four storage devices in each data center, and each storage device has four Fibre
Channel interfaces. Each data center has 32 servers, and each server has two host bus adapters.
The majority of the servers require only 20 to 30MBps of throughput on average, but four of the
servers require 150 MBps of throughput on average. What will provide the most cost-effective
design to satisfy these requirements?
A. two Cisco MDS 9216 Fabric Switches in each data center, each MDS 9216 with an additional
16-portFibre Channel line card
B. two Cisco MDS 9509 Multilayer Directors with one in each data center, each MDS 9509 with
two 16-portFibre Channel line cards and three 32-port Fibre Channel line cards
C. two Cisco MDS 9216 Fabric Switches in each data center, each MDS 9216 with an additional
32-portFibre Channel line card
D. two Cisco MDS 9506 Multilayer Directors with one in each data center, each MDS 9506 with
two 16-portFibre Channel line cards and two 32-port Fibre Channel line cards
