FC/FCoE oversubscription ratios refer to the relationship between the bandwidth provided and the bandwidth required. Common types of oversubscription ratios include port bandwidth to uplink bandwidth (B), which measures the bandwidth available at the access layer compared to the uplink, and host bandwidth to storage bandwidth (D), which relates to the bandwidth demand from servers compared to the available storage bandwidth.

 The device-alias confirm-commit command is used in Cisco MDS 9000 Series Switches to ensure that changes made to device aliases are confirmed before being committed to the database. This command prompts the user for confirmation and displays the pending changes explicitly on the console, which aligns with the requirements stated in the question.

References: For more detailed information, you would typically refer to the Cisco Data Center Core Technologies study guide or the official Cisco documentation for the MDS 9000 Series.

Placing all EPGs in the preferred group within a VRF allows for communication between them without the need for additional contracts. This is because the preferred group feature in Cisco ACI allows EPGs within the same VRF to communicate with each other by default, bypassing the need to provide and consume contracts1. This simplifies the configuration process when new EPGs and bridge domains are added, as they inherit this communication capability by being part of the preferred group1.

References := For more information on the implementation of VRFs and the use of the preferred group feature in Cisco ACI, you can refer to the Cisco documentation on “Use vzAny to Automatically Apply Communication Rules to all EPGs in a VRF” and other related resources1. These documents provide detailed guidance on how to configure VRFs and EPGs to achieve seamless communication within the network infrastructure.

To monitor traffic between leaf switches in a Cisco ACI network and support filtering traffic from a Bridge Domain or VRF, the configuration must allow for specifying the traffic of interest based on tenant, application, and EPG. Option C, filter tenant t1 application app1 epg epg1, meets these requirements by defining a filter that targets traffic from a specific EPG within an application profile in the tenant ‘t1’. This filter can be applied to the monitoring session to capture the relevant traffic.

References := For detailed procedures on implementing monitoring sessions in Cisco ACI, refer to the Cisco Data Center Core Technologies documentation, particularly sections covering ACI traffic monitoring and filtering.

 To connect Cisco UCS Manager directly to an FC storage port, the fabric interconnect must be configured in FC switch mode, which allows it to manage Fibre Channel traffic and zoning. Additionally, creating the required VSAN in the SAN cloud is necessary to define a virtual storage area network that can be associated with the storage ports on the fabric interconnect.

References: Detailed steps for these actions can be found in the Cisco documentation, which outlines the process of configuring direct attached storage and FC zoning with Cisco UCS Manager

The Peer Gateway feature on Cisco Nexus switches is designed to address the exact scenario described. When enabled, it allows the vPC peer switches to forward traffic based on the SVI MAC address, even if it is not the HSRP MAC address. This is particularly useful in cases where end devices do not use the HSRP virtual MAC address for the gateway and instead use the physical MAC address of one of the HSRP routers1. By using the Peer Gateway feature, both N9K_1 and N9K_2 will be able to forward traffic for VLAN 23, ensuring that the packets are not dropped due to the vPC loop prevention mechanism123.

References: = This information is supported by Cisco’s documentation on Nexus 5500 Platform Layer 3 and vPC Operations, which explains the use of the peer-gateway command to allow Layer 3 forwarding in scenarios where the destination MAC of the incoming packet is the MAC of its vPC peer switch1. Additionally, discussions in the Cisco Community confirm the necessity of this feature when certain devices on the network do not properly send traffic to the MAC address specified in the ARP234

The Cisco UCS Python SDK (D) is a set of Python libraries that provide a method for automating the configuration and management of Cisco Unified Computing System (UCS) hardware. It allows network administrators to write custom scripts or develop applications to manage UCS environments programmatically. In the context of creating a Django self-service portal for VLAN automation, the UCS Python SDK would be used to interact with the UCS Manager’s API, enabling the automation of VLAN creation and other tasks1.

References: The use of the Cisco UCS Python SDK for automating tasks in UCS Manager is discussed in Cisco’s official blogs and community forums, where examples and best practices can be found12. The SDK provides a more direct and tailored approach for UCS automation compared to other tools, making it suitable for integration with custom Django applications.

Option C is the correct command to make an XML backup of Cisco UCS Manager. The command creates a backup file named “all-config9.bak” that contains all system and service profiles configuration. The command also specifies the protocol as SCP (Secure Copy Protocol), which transfers the backup file using an authenticated and encrypted tunnel. References:

The command “show install all impact epld bootflash:n9000-epld.6.1.2.13.1.img” is used to display the impact of the EPLD (Electronic Programmable Logic Device) upgrade on the operation of the Cisco Nexus 9000 series switch. This command does not perform the upgrade; instead, it provides a report that shows what the upgrade would affect if it were to be executed. This is useful for planning and ensuring that the upgrade will not disrupt critical services or operations on the switch. References :=
