Which of the following are not capable of operating as a standalone physical switch? (Choose two.)
- Nexus 5000 Series
- Nexus 2000 Series
- Nexus 7000 Series
- Nexus 9000 Series
- Nexus 1000v Series
Of the available choices, neither the Cisco Nexus 1000v Series nor the Cisco Nexus 2000 Series are capable of operating as a standalone physical switch. The Cisco Nexus 1000v is a virtual switch that is capable of connecting to upstream physical switches in order to provide connectivity for a virtual machine (VM) network environment. Although the Cisco Nexus 1000v operates similar to a standard switch, it exists only as software in a virtual environment and is therefore not a physical switch.
The Cisco Nexus 2000 Series of switches are fabric extenders (FEXs) and cannot operate as standalone switches. FEX technologies depend on parent switches, such as a Cisco Nexus 5500 Series switch or a Cisco Nexus 7000 Series switch, to provide forwarding tables and control plane functionality. FEX technologies are intended to extend the network to edge devices. Typically, FEX devices in the Cisco Nexus 2000 Series are managed by first connecting to the parent device using either Telnet or Secure
Shell (SSH) and then configuring the FEX.
Cisco Nexus 5000 Series switches operate as standalone physical switches. Cisco Nexus 5000 Series switches are data center access layer switches that can support 10-gigabit-per-second (Gbps) or 40-Gbps Ethernet, depending on the model. Native Fibre Channel (FC) and FC over Ethernet (FCoE) are also supported by Cisco Nexus 5000 Series switches.
Cisco Nexus 7000 Series switches operate as standalone physical switches. Cisco Nexus 7000 Series switches are typically used as an end-to-end data center solution, which means that the series is capable of supporting all three layers of the data center architecture: core layer, aggregation layer, and access layer. In addition, the Cisco Nexus 7000 Series supports virtual device contexts (VDCs). The Cisco Nexus 7000 Series can support up to 100-Gbps Ethernet.
Cisco Nexus 9000 Series switches operate as standalone physical switches. Cisco Nexus 9000 Series switches can operate either as traditional NX-OS switches or in an Application Centric Infrastructure (ACI) mode. Unlike Cisco Nexus 7000 Series, Cisco Nexus 9000 Series switches do not support VDCs or storage protocols.
