Designing Cisco Data Center Infrastructure (DCID) — Question 121

An engineer must implement an iSCSI storage connectivity in the existing Cisco UCS environment. The environment is based on Cisco UCS С-Series rack server, Cisco Nexus 1000V Series Switches, and VMware ESXi hosts. The implementation must meet these requirements:

• Provide multipathing and high availability in the event of a critical path failure.
• Be cost-effective and not require the purchase of new equipment.

Which two components must be selected to meet these requirements? (Choose two.)

Answer options

• A. software iSCSI adapter
• B. storage binding
• C. uplink pinning
• D. system VLAN
• E. hardware iSCSI NIC

Correct answer: A, B

Explanation

The software iSCSI adapter (A) allows for multipathing and does not require additional hardware, making it a cost-effective solution. Storage binding (B) helps to establish a connection between the datastore and the storage system, ensuring high availability. Uplink pinning (C), system VLAN (D), and hardware iSCSI NIC (E) do not address the requirements for multipathing and high availability in a cost-effective manner.
