1. Topic 1, Cisco Data Center Architecture

Which three capabilities make the Cisco Nexus 7010 switch an effective solution for the data center core?

(Choose three.)

A. virtualization

B. unified I/O

C. support for 48-port Gb/s line card

D. support for Data Center Service Modules

E. high performance

F. high availability

Answer: B,E,F

Explanation:

The Cisco Nexus 7000 F2-Series Module also delivers integrated FCoE, greatly simplifying the network

infrastructure and reducing costs by enabling the deployment of unified data center fabrics to consolidate

data center traffic onto a single, general-purpose, high-performance, highly available network. With the

Cisco Nexus 7000 F2-Series Module, FCoE can be deployed in director-class modular platforms for the

access and core of converged networks. In addition to FCoE host and target support, the module provides

virtual expansion port (VE-port) support, allowing creation of FCoE Inter-Switch Links (ISLs) and enabling

scalable, multi-hop FCoE topologies.

Answer: B

Explanation:

Cisco UCS 2200 Series Fabric Extenders bring the unified fabric into the blade server enclosure,

providing multiple 10 Gigabit Ethernet connections between blade servers and the fabric interconnect,

simplifying diagnostics, cabling, and management. It is a second-generation I/O module (IOM) that shares

the same form factor with the first-generation Cisco UCS 2100 Series Fabric Extenders IOM and is

backward-compatible with the shipping Cisco UCS 5108 Blade Server Chassis.

The Cisco UCS 2200 Series extends the I/O fabric between the Cisco UCS 6100 and 6200 Series Fabric

Interconnects and the Cisco UCS 5100 Series Blade Server Chassis, enabling a lossless and

deterministic Fibre Channel over Ethernet (FCoE) fabric to connect all blades and chassis together. Since

the fabric extender is similar to a distributed line card, it does not perform any switching and is managed

as an extension of the fabric interconnects. This approach removes switching from the chassis, reducing

overall infrastructure complexity and enabling Cisco UCS to scale to many chassis without multiplying the

number of switches needed, reducing TCO and allowing all chassis to be managed as a single, highly

available management domain.

The Cisco UCS 2200 Series also manages the chassis environment (the power supply and fans as well

as the blades) in conjunction with the fabric interconnect. Therefore, separate chassis management

modules are not required.

3.FabricPath brings the benefits of routing protocols to layer 2 network Ethernet environments.

What are the advantages of using FabricPath technology? (Choose three.)

A. FabricPath provides MAC address scalability with conversational learning

B. Loop mitigation with TTL in the frame field

C. STP independence

D. 10 Gbps bandwidth

E. Layer 2 extensions between data centers

Answer: A,B,C

Explanation:

The advantages of using FabricPath include:

• MAC address scalability with conversational learning

• Spanning Tree Protocol independence: No reliance on Spanning Tree anymore. Each switch has a

complete view of the Layer 2 topology, and it calculates the Layer 2 forwarding table based a

shortest-path-first calculation.

• Traffic distribution for unicast: Unicast Layer 2 traffic can take multiple equal-cost Layer 2 paths.

• Traffic distribution for multicast on multiple distribution trees: Multicast traffic can be distributed

along two multidestination trees.

• More direct communication paths: Any topology is possible, so cabling two access or edge switches

directly to each other creates a direct communication path, unlike what happens with Spanning Tree.

• Simplicity of configuration: The configuration of FabricPath is very simple. Tuning may still be advised

but by default the switches negotiate switch-ids allocation with a protocol called Dynamic Resource

Allocation Protocol (DRAP).

• Loop mitigation with TTL in the frame field: Layer 2 loops, as they are known of today in

Spanning-Tree-Protocol-based Layer 2 networks, are mitigated by dropping frames that have been

propagated across too many hops. The Layer 2 FabricPath frames include a Time to Live (TTL) field that

is decremented at each hop. The value of the TTL field is 32.

4.Which three concepts influenced the evolution of data centers? (Choose three.)

A. Consolidation

B. Expansion

C. Automation

D. Virtualization

E. Commoditization

F. Economics

Answer: A,C,D

Explanation:

Data center transformation takes a step-by-step approach through integrated projects carried out over

time. This differs from a traditional method of data center upgrades that takes a serial and siloed approach.

[9] The typical projects within a data center transformation initiative include standardization/consolidation,

virtualization, automation and security.

5. Topic 2, Cisco Data Center Infrastructure—Cisco NX-OS

A network administrator has installed an N7K-F248-25XP module into an existing chassis. The module is

powered on, but the interfaces are all in VDC0.

What is the reason for this?

A. The chassis needs an EPLD upgrade to support the new module type.

B. The default VDC cannot support F2 modules.

C. The interfaces must be allocated into a VDC for F2 modules only.

D. The module has failed GOLD diagnostics, and the switch has isolated the ports to protect the integrity

of the system.

Answer: C

Explanation:

The F2-Series Cisco’s VDC feature helps enable the virtualization of a single physical device in one or

more logical devices. Each of the provisioned logical devices is configured and managed as if it were a

separate physical device
