You want to extend the Layer 2 fabric of a data center’s network from its Cisco 7000 Series switches without the addition of unnecessary administrative overhead and configuration.
Which of the following devices are you most likely to add to the deployment?
- the Cisco Nexus 2000 Series switch
- the Cisco Nexus 1000v switch
- the Cisco Nexus 5000 Series switch
- the Cisco Nexus 9000 Series switch
Explanation:
Most likely, you will add a Cisco Nexus 2000 Series switch to the deployment if you want to extend the Open Systems Interconnection (OSI) Layer 2 fabric of a data center’s network from its Cisco 7000 Series switches without the addition of unnecessary administrative overhead and configuration. The Cisco Nexus 2000 Series of switches are fabric extenders (FEXs) and cannot operate as standalone switches. By default, Cisco FEX devices are not configured with software. Instead, they depend on parent switches, such as a Cisco Nexus 7000 Series switch, to install and configure software, provide forwarding tables, and provide control plane functionality.
You are not likely to add a Cisco Nexus 1000v to the deployment, because adding that device would create additional administrative overhead and configuration. 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.
You are not likely to add a Cisco Nexus 5000 Series switch to the deployment, because adding that device would create additional administrative overhead and configuration. 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.
You are not likely to add a Cisco Nexus 9000 Series switch to the deployment, because adding that device would create additional administrative overhead and configuration. 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 virtual device contexts (VDCs) or storage protocols.
