Implementing Cisco Data Center Infrastructure

Question No: 1 – (Topic 1)

Which GLBP load-balancing algorithm ensures that a client is always mapped to the same VMAC address?

  1. vmac-weighted

  2. dedicated-vmac-mode

  3. shortest-path and weighting

  4. host-dependent

Answer: D Explanation:

Host dependent-GLBP uses the MAC address of the host to determine which virtual MAC address to direct the host to use. This algorithm guarantees that a host gets the same virtual MAC address if the number of virtual forwarders does not change.

Question No: 2 – (Topic 1)

Which statement about RADIUS configuration distribution using Cisco Fabric Services on a Cisco Nexus 7000 Series Switch is true?

  1. Cisco Fabric Services does not distribute the RADIUS server group configuration or server and global keys.

  2. Enabling Cisco Fabric Services causes the existing RADIUS configuration on your Cisco NX-OS device to be immediately distributed.

  3. When the RADIUS configuration is being simultaneously changed on more than one device in a Cisco Fabric Services region, the most recent changes will take precedence.

  4. Only the Cisco NX-OS device with the lowest IP address in the Cisco Fabric Services region can lock the RADIUS configuration.

Answer: A Explanation:

CFS does not distribute the RADIUS server group configuration or server and global keys.

The keys are unique to the Cisco NX-OS device and are not shared with other Cisco NX- OS devices.

Question No: 3 – (Topic 1)

Which statement explains why a Cisco UCS 6200 Fabric Interconnect that is configured in end-host mode is beneficial to the unified fabric network?

  1. There is support for multiple (power of 2) uplinks.

  2. Upstream Layer 2 disjoint networks will remain separated.

  3. The 6200 can connect directly via vPC to a Layer 3 aggregation device.

  4. STP is not required on the uplink ports from the 6200.

Answer: D Explanation:

In Cisco Unified Computing System environments, two Ethernet switching modes determine the way that the fabric interconnects behave as switching devices between the servers and the network. In end-host mode, the fabric interconnects appear to the upstream devices as end hosts with multiple links. In end-host mode, the switch does not run Spanning Tree Protocol and avoids loops by following a set of rules for traffic forwarding. In switch mode, the switch runs Spanning Tree Protocol to avoid loops, and broadcast and multicast packets are handled in the traditional way.

Question No: 4 – (Topic 1)

Refer to the command below. When configuring an SVS connection on the Cisco Nexus

5000 Series Switch, which device is being referenced as the remote IP address? nexus5500-2(config-svs-conn)# remote ip address port 80 vrf management

  1. ESX or ESXi host

  2. vCenter

  3. vPC peer switch

  4. Cisco IMC management

Answer: B Explanation:

This command specifies the hostname or IP address for the vCenter Server. Optionally, specifies the port number and VRF.

Question No: 5 – (Topic 1)

Which protocol is the foundation for unified fabric as implemented in Cisco NX-OS?

  1. Fibre Channel

  2. Data Center Bridging

  3. Fibre Channel over Ethernet

  4. N proxy virtualization

  5. 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 No: 6 – (Topic 1)

On a Cisco Nexus 7000 Series router, which statement about HSRP and VRRP is true?

  1. When VDCs are in use, only VRRP is supported.

  2. HSRP and VRRP both use the same multicast IP address with different port numbers.

  3. HSRP has shorter default hold and hello times.

  4. The VRRP group IP address can be the same as the router-specific IP address.

Answer: D Explanation:

VRRP allows for transparent failover at the first-hop IP router by configuring a group of routers to share a virtual IP address. VRRP selects a master router in that group to handle all packets for the virtual IP address. The remaining routers are in standby and take over if the master router fails.

Question No: 7 – (Topic 1)

Which statement about SNMP support on Cisco Nexus switches is true?

  1. Cisco NX-OS only supports SNMP over IPv4.

  2. Cisco NX-OS supports one instance of the SNMP per VDC.

  3. SNMP is not VRF-aware.

  4. SNMP requires the LAN_ENTERPRISE_SERVICES_PKG license.

  5. Only users belonging to the network operator RBAC role can assign SNMP groups.

Answer: B Explanation:

Cisco NX-OS supports one instance of the SNMP per virtual device context (VDC). By default, Cisco NX-OS places you in the default VDC. SNMP supports multiple MIB module instances and maps them to logical network entities. SNMP is also VRF aware. You can configure SNMP to use a particular VRF to reach the SNMP notification host receiver. You can also configure SNMP to filter notifications to an SNMP host receiver based on the VRF where the notification occurred.

Question No: 8 – (Topic 1)

Which statement about the Layer 3 card on the Cisco Nexus 5500 Series Switch is true?

  1. BGP support is not provided, but RIP, EIGRP, and OSPF support is provided.

  2. Up to two 4-port cards are supported with up to 160 Gb/s of Layer 3 forwarding capability.

  3. Up to 16 FEX connections are supported.

  4. Port channels cannot be configured as Layer 3 interfaces.

Answer: C Explanation:

From the Cisco NX-OS 5.1(3)N1(1) release and later releases, each Cisco Nexus 5500 Series device can manage and support up to 24 FEXs without Layer 3. With Layer 3, the number of FEXs supported per Cisco Nexus 5500 Series device is 8. With Enhanced vPC and a dual-homed FEX topology each FEX is managed by both Cisco Nexus 5000 Series devices. As a result, one pair of Cisco Nexus 5500 Series devices can support up to 24 FEXs and 16 FEXs for Layer 2 and Layer 3.

Question No: 9 – (Topic 1)

Which two statements about Cisco Nexus 7000 line cards are true? (Choose two.)

  1. M1, M2, and F1 cards are allowed in the same VDC.

  2. M line cards are service-oriented and likely face the access layer and provide Layer 2 connectivity.

  3. F line cards are performance-oriented and likely connect northbound to the core layer for Layer 3 connectivity.

  4. M line cards support Layer 2, Layer 3, and Layer 4 with large forwarding tables and a rich feature set.

  5. The F2 line card must reside in the admin VDC.

Answer: A,D Explanation:

Cisco is introducing a new line card called as F3 Module which has rich feature set and offers high performance 40G/100G port density to the Nexus 7000 product family. Cisco also introduced a new feature in NX-OS 6.2(2) where the F2e line card can be in the same VDC as M1 or M2 Line Card. The objective of this session is to cover detailed steps and methodology of migrating Nexus 7000 with VDC types prior to NX-OS 6.2 to the newer F3 or M/F2e VDC types. The session also covers the effect of VDC migration with commonly used Network features, firewall and load balancer services.

M-Series XL modules support larger forwarding tables. M-Series modules are frequently required at network core, peering, and aggregation points. When used with the F1-Series, the M-Series modules provide inter-VLAN services and form a pool of Layer 3 resources for the system.

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.
