Implementing Cisco Data Center Unified Fabric
Question No: 61 – (Topic 6)
Which two items are features that are available in VN-Link in software? (Choose two.)
-
VM snapshot
-
NetFlow
-
ERSPAN
-
high availability
-
resource reservations
Answer: B,C Explanation:
NetFlow is a feature that was introduced on Cisco routers that provides the ability to collect IP network traffic as it enters or exits an interface. By analyzing the data provided by NetFlow, a network administrator can determine things such as the source and destination of traffic, class of service, and the causes of congestion. A typical flow monitoring setup
(using NetFlow) consists of three main components:
->Flow exporter: aggregates packets into flows and exports flow records towards one or more flow collectors.
->Flow collector: responsible for reception, storage and pre-processing of flow data received from a flow exporter.
->Analysis application: analyzes received flow data in the context of intrusion detection or traffic profiling,
This module describes how to configure Encapsulated Remote Switched Port Analyzer (ERSPAN). The Cisco ERSPAN feature allows you to monitor traffic on one or more ports or VLANs and send the monitored traffic to one or more destination ports.

Which three VDC resources can be constrained with a resource template? (Choose three.)
-
ACLs
-
NAT entries
-
IPv4 routes
-
IPv6 routes
-
SPAN sessions
-
RBAC users
Answer: C,D,E Explanation:
VDC resource templates set the minimum and maximum limits for shared physical device resources when you create the VDC. The Cisco NX-OS software reserves the minimum limit for the resource to the VDC. Any resources allocated to the VDC beyond the minimum are based on the maximum limit and availability on the device.
You can explicitly specify a VDC resource template, or you can use the default VDC template provided by the Cisco NX-OS software. VDC templates set limits on the following resources:
->IPv4 multicast route memory
->IPv6 multicast route memory
->IPv4 unicast route memory
->IPv6 unicast route memory
->Port channels
->Switch Port Analyzer (SPAN) sessions
->VLANs
->Virtual routing and forwarding instances (VRFs)

Question No: 69 – (Topic 7)
Which FCoE component is responsible for the encapsulation and de-encapsulation of Fibre Channel frames in Ethernet?
-
distributed FCF
-
FCoE node
-
FCoE logical endpoint
-
Fibre Channel forwarder
-
FCoE forwarder
Answer: C Explanation:
The FCoE Logical Endpoint (FCoE_LEP) is responsible for the encapsulation and deencapsulation functions of the FCoE traffic. FCoE_LEP has the standard Fibre Channel layers, starting with FC-2 and continuing up the Fibre Channel Protocol stack.
