QUESTION 62
What is an Overlay Transport Virtualization extended VLAN?
A. the VLAN used to locate other AEDs
B. the VLAN used to access the overlay network by the join interface
C. the user VLAN that exists in multiple sites
D. the VLAN that must contain the overlay interface
Answer: C
Explanation:
Functions of OTV
– Maintains a list of overlays
– Maintains a list of configured overlay parameters such as name, multicast address, encapsulation type, authentication, and OTV feature sets
– Maintains the state of the overlay interface
– Maintains the status of OTV VLAN membership from Ethernet infrastructure and the state of the authoritative edge device (AED) from IS-IS
– Maintains a database of overlay adjacencies as reported by IS-IS
– Maintains IP tunnel information and manages the encapsulation for data sent on the overlay network
– Manages delivery groups (DGs) for each overlay by snooping multicast traffic and monitoring traffic streams for active DGs
– Configures, starts, and stops the OTV IS-IS instance
– Interfaces with IP multicast to join provider multicast groups for each overlay

QUESTION 63
Refer to the exhibit. What is the consequence of configuring peer-gateway on the two vPC peers N7K-1 and N7K-2?
A. Nothing, this is the standard vPC configuration to make the feature work.
B. The downstream device detects only one of the vPC peers as its gateway.
C. The downstream device can use DMAC of N7K-1 on the link to N7K-2, and N7K-2 forwards the packet.
D. This configuration enables the downstream device to use DHCP to obtain its default gateway.
Answer: C
Explanation:
Beginning with Cisco NX-OS 4.2(1), you can configure vPC peer devices to act as the gateway even for packets that are destined to the vPC peer device’s MAC address. Use the peer-gateway command to configure this feature. Some network-attached storage (NAS) devices or load-balancers may have features aimed to optimize the performances of particular applications. Essentially these features avoid performing a routing-table lookup when responding to a request that originated form a host not locally attached to the same subnet. Such devices may reply to traffic using the MAC address of the sender Cisco Nexus 7000 device rather than the common HSRP gateway. Such behavior is non-complaint with some basic Ethernet RFC standards.

A. An emulated switch ID must be unique when the vPC+ feature is used.
B. Switches with FabricPath and vPC+ consume two switch IDs.
C. Emulated switch IDs must be numbered from 1 to 99.
D. Each switch ID must be unique in the FabricPath topology.
E. Switch IDs must be configured manually.
Answer: BDE

QUESTION 65
Which statement about core-edge SAN topology is true?
A. Converged FCoE links connect the core and edge MDS switches.
B. The SAN core connects to the network aggregation layer.
C. Separate links with the same I/O are used for SAN and LAN traffic.
D. Storage devices are accessed via FCoE over the LAN network.
Answer: B
Explanation:
The Aggregation layer of the data center provides connectivity for the Access layer switches in the server farm, an aggregates them into a smaller number of interfaces to be connected into the Core layer. In most data center environments, the Aggregation layer is the transition point between the purely Layer 3 routed Core layer, and the Layer 2-switched Access layer. 802.1Q trunks extend the server farm VLANs between Access and Aggregation layers. The Aggregation layer also provides a common connection point to insert services into the data flows between clients and servers, or between tiers of servers in a multi-tier application.
QUESTION 66
What configuration is required when implementing FCoE?
A. disable LAN traffic on the interface
B. configure PortFast on the access port
C. permit all VLANs on the interface
D. permit all VSANs on the interface
Answer: A
Explanation:
DCBX allows the switch to send a LAN Logical Link Status (LLS) message to a directly-connected CNA. Enter the shutdown lan command to send an LLS-Down message to the CNA. This command causes all VLANs on the interface that are not enabled for FCoE to be brought down. If a VLAN on the interface is enabled for FCoE, it continues to carry SAN traffic without any interruption.

QUESTION 67
Drag and Drop
Drag the network characteristics on the left to the most appropriate design layer on the right.
Answer:
Explanation:
The access layer is the first tier or edge of the campus. It is the place where end devices (PCs, printers, cameras, and the like) attach to the wired portion of the campus network. It is also the place where devices that extend the network out one more level are attached — IP phones and wireless access points (APs) being the prime two key examples of devices that extend the connectivity out one more layer from the actual campus access switch. The wide variety of possible types of devices that can connect and the various services and dynamic configuration mechanisms that are necessary, make the access layer one of the most feature-rich parts of the campus network. You can enable an 802.1X port for port security by using the dot1x multiple-hosts interface configuration command. You must also configure port security on the port by using the switchport port-security interface configuration command. With the multiple-hosts mode enabled, 802.1X authenticates the port, and port security manages network access for all MAC addresses, including that of the client. You can then limit the number or group of clients that can access the network through an 802.1X multiple-host port.

QUESTION 68
Which topology is not supported when using vPC?
A. a single-homed server to a single FEX that is connected to two Cisco Nexus 5500 Series Switches
B. a dual-homed server to two FEXs, each connected to two Cisco Nexus 5500 Series Switches
C. a dual-homed server to two FEXs that are connected to one Cisco Nexus 5500 Series Switch
D. a dual-homed server to a single FEX that is connected to two Cisco Nexus 5500 Series Switches
Answer: C
Explanation:
The figure shows unsupported topology where a vPC is between hosts and two FEXs that are connected to one Cisco Nexus 5500 Series device. This topology does not provide a good high availability solution because the server loses the connectivity to the network when the Cisco Nexus 5000 Series device fails. If you need to connect a multi-homing server to a pair of FEXs when there is only one Cisco Nexus 5000 Series device, you have the option to run active or standby NIC teaming from the server.

QUESTION 69
Which protocol is the foundation for unified fabric as implemented in Cisco NX-OS?
A. Fibre Channel
B. Data Center Bridging
C. Fibre Channel over Ethernet
D. N proxy virtualization
E. N Port identifier virtualization
Answer: C
Explanation:
Fibre Channel over Ethernet (FCoE) is one of the major components of a Unified Fabric. FCoE is a new technology developed by Cisco that is standardized in the Fibre Channel Backbone 5 (FC-BB-5) working group of Technical Committee T11 of the International Committee for Information Technology Standards (INCITS). Most large data centers have huge installed bases of Fibre Channel and want a technology that maintains the Fibre Channel model. FCoE assumes a lossless Ethernet, in which frames are never dropped (as in Fibre Channel) and that therefore does not use IP and TCP.

QUESTION 75
Hotspot
What is effect of the command “fabric path load-balance unicast layer 3”?
A. It configures F2 VDC FabricPath unicast load balancing
B. The command automatically load balances broadcast traffic
C. It configures F1/MI VDC FabricPath unicast load balancing
D. It configures M1 VDC FabricPath unicast load balancing
Answer: C
Explanation:
The F1 cards are complemented by M1 card for routing purposes. When using M1 cards in the same virtual device context (VDC) as the F1 card, routing is offloaded to the M1 cards, and more routing capacity is added to the F1 card by putting more M1 ports into the same VDC as the F1 card.
