300-610試験無料問題集「Cisco Designing Cisco Data Center Infrastructure 認定」
A customer asks an engineer to develop a framework to configure Cisco services that will be used to replace process of manual device configuration. The engineer plans to use a programmatic interface and must keep these considerations in mind:
- The customer's environment requires the script to authenticate before executing further actions.
- The customer's security requirements mandate the use of HTTPS
transport.
- The support stall has limited shell scripting knowledge, so the
scripts should be easy to read and write and be serf-documenting.
Which two solutions should be used to meet these requirements? (Choose two.)

A Cisco engineer is analyzing a customer environment where dozens of VMs are running on a physical server and UCS chassis are cascaded. The setup uses two ISLs in a port channel to the SAN switch (per fabric). The oversubscription from VM to physical SAN port is often 20 (VMs/host) x 72 (9 UCS chassis cascaded = 72 hosts):
2 ISLs from fabric interconnect to SAN switch port on the NPV core (NPIV enabled switch) This results to 20 x 72 2 per single ISL = 720 VMs per ISL 20 (VMs per host) x 8 (hosts per chassis) x 9 (chassis per port channel to SAN switch) / 2 (ISLs per port channel) = 20 x 8 x 9 / 2 =
720 VMs per SAN F-port
What is the best way to resolve possible IOPS bottleneck?

An engineer must logically partition two Cisco Nexus 7000 Series Switches into two environments called Test_39919596 and Production_59423879. The environments must use only F2-Series line cards and be limited to a maximum of 265 port-channels.
Which Cisco Nexus feature must be used?

Drag and Drop Question
Drag and drop the feature descriptions from the left onto the correct UCS Fabric Interconnect modes on the right.
Drag and drop the feature descriptions from the left onto the correct UCS Fabric Interconnect modes on the right.
正解：
Explanation:
End-host mode features include:
- Spanning Tree Protocol is not run on both the uplink ports and the server ports.
- MAC address learning occurs only on the server ports; MAC address movement is fully supported.
- Links are active-active regardless of the number of uplink switches.
- The system is highly scalable because the control plane is not occupied.
Ethernet switching mode features include:
- Spanning Tree Protocol is run on the uplink ports per VLAN as defined by Cisco Per-VLAN Spanning Tree Plus (PVST+)
- Configuration of Spanning Tree Protocol parameters (bridge priority, hello timers, etc.) is not supported.
- VLAN Trunk Protocol (VTP) is not supported.
- MAC address learning and aging occur on both the server and uplink ports as in a typical Layer 2 switch.
- Upstream links are blocked according to Spanning Tree Protocol rules.
Refer to the exhibit. A high-availability setup for iSCSI is designed with the host running iSCSI multipath software. Each IP storage port on the MDS switch exports the same two Fibre Channel target ports with different iSCSI target names.
In this design, how many iSCSI sessions are created from the host so that recovery occurs if any component fails?

Refer to the exhibit. The Cisco Nexus Series Switch with hostname Nexus1 is the default gateway for server A and server B.
Both servers must have reachability to the internet, however, server A internet traffic must pass through the firewall for deep packet inspection. Also, the firewall must inspect any communication between server A and server B. Which solution must be applied to separate the data plane path for server A and server B?

Refer to the exhibit. A Cisco engineer is configuring a PBR in a Cisco ACI data center scenario and plans to insert a transparent firewall. The APIC release is 4.1, the Cisco ACI fabric is configured to be the gateway for the servers and for the PBR node, and the Layer 4/ Layer 7 devices are deployed as Layer 1/ Layer 2 mode in the physical domain. Layer 1/Layer 2 PBR node interfaces are also configured to be in a bridge domain and not in an L3Out. What is required for the consumer and provider connectors of the Layer 1/Layer 2 device for this scenario to work?
