NEW QUESTION 5
Which technology does Cisco recommend tor connecting a main data center to a remote data center?

• A. LISP

NEW QUESTION 6
Which component is required to run FCoE?

• A. converged network adapter
• B. iSCSI gateway
• C. host bus adapter
• D. Fibre Channel adapter

Answer: A

Explanation: Computers can connect to FCoE with converged network adapters (CNAs), which contain both Fibre Channel host bus adapter (HBA) and Ethernet Network Interface Card (NIC) functionality on the same adapter card. CNAs have one or more physical Ethernet ports. FCoE encapsulation can be done in software with a conventional Ethernet network interface card, however FCoE CNAs offload (from the CPU) the low level frame processing and SCSI protocol functions traditionally performed by Fibre Channel host bus adapters.

NEW QUESTION 12
You have a Cisco Nexus 5500 Series switch. What is the default load-balancing hash mechanism for traffic on FCoE port channels?

• A. the source MAC address
• B. the source IP address and the destination IP address
• C. the source MAC address and the destination MAC address
• D. the source TCP or UDP port and the destination TCP or UDP port

Answer: B

Explanation: On Nexus 5500 the default load balancing mechanism on the LACP port-channel for FCoE traffic is
"source-destination". In this default state, all the FCoE traffic takes the same link in the port-channel when the Nexus 5500 forwards frames over FCoE VE ports. In order to enable all links to be used in the port-channel
for FCoE traffic, enter the port-channel load-balance ethernet source-dest-port command to configure Nexus 5500 "port-channel load balancing" to "source-dest-port". With this configuration "source-destination-oxid" load balancing is used for FCoE traffic.

NEW QUESTION 13
Which option must be enabled to allow line-rate forwarding on a Fibre Channel port?

• A. F port
• B. TEport
• C. dedicated mode
• D. shared mode
• E. E port

Answer: C

NEW QUESTION 14
Which technology can you use to create separate routing tables for different tenants that are hosted on the same Cisco NX-OS platform?

• A. Cisco FabricPath
• B. VLANs
• C. vPC
• D. VRF

Answer: D

Explanation: http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/nx-os/vxlan/configuration/guide/b_NX-OS_VXL

NEW QUESTION 15
Refer to exhibit.

What is the result of the configuration

• A. The interface is disable if aggressive UDLD is configure on neighbor interface
• B. UDLD attempt to reestablish the connection to the neighbor by sending packets every second for 8 seconds before disable
• C. The interface operates a point to multipoint interface
• D. UDLD attempt to reestablish the connection to the neighbor once before disabling the port

Answer: D

NEW QUESTION 16
Which statement accurately describes the configuration requirements for disjoint Layer 2 networks on Cisco UCS?

• A. MPIO
• B. host vPC
• C. VEM
• D. VSS
• E. VSM

Answer: CE

Explanation: When server virtualization is implemented, the edge of the network is pushed from the traditional location in the network access layer, implemented in physical switches, to the virtual network access layer that is implemented in software in the server hypervisor. The Cisco Nexus 1000V Switch is an intelligent virtual network access layer switch that runs Cisco NX-OS Software, Cisco's data center operating system that runs on all Cisco data center products. Operating inside the Microsoft Hyper-V hypervisor, the Cisco Nexus 1000V supports Cisco Virtual Network Link (VN-Link) server virtualization technology to provide:
Policy-based virtual machine connectivity
Mobile virtual machine security and network policy
Nondisruptive operating model for your server virtualization and networking teams
When server virtualization is implemented in the data center, servers and virtual machines are not managed the same way as physical servers. Server virtualization is treated as a special deployment, leading to longer
deployment time, with more coordination needed among server, network, storage, and security administrators. With the Cisco Nexus 1000V, you have a consistent networking feature set and configuration and provisioning model for both the physical and the virtual networks. Virtual machine networks can use the same network configuration, security policy, diagnostic tools, and operating models as physical server deployments that are connected to physical switches. This unified approach provides faster deployment and troubleshooting and makes the administration of virtualization environments essentially the same as for nonvirtualized deployments.
Developed in close collaboration with Microsoft, the Cisco Nexus 1000V Switch is certified by Microsoft and integrates with Microsoft Windows Server and Microsoft System Center Virtual Machine Manager
(SCVMM). You can use the Cisco Nexus 1000V to manage your virtual machine connectivity with confidence
in the integrity of the server virtualization infrastructure.
Cisco Nexus 1000V Switch Components
Cisco Nexus 1000V Switches have two main components:
Virtual supervisor module (VSM)
Virtual Ethernet module (VEM)
The VSM provides the switch control and management plane, and the VEM provides the data plane for the switch (Figure 1). The VSM can run as a virtual machine on any Microsoft Hyper-V host or as a virtual service node on the Cisco Nexus 1010 and 1110. The VEM runs as a plug-in (extension) to the Microsoft Hyper-V switch in the hypervisor kernel, providing switching between virtual machines.
Cisco Nexus 1000V sees the VSMs and VEMs as modules. In the current release, a single VSM can manage up to 64 VEMs. The VSMs are always associated with slot numbers 1 and 2 in the virtual chassis. The VEMs are sequentially assigned to slots 3 through 66 based on the order in which their respective hosts were added to the Cisco Nexus 1000V Switch.

NEW QUESTION 18
