In the ERSPAN configuration provided, Host B is connected to Switch A and is configured as the source of the ERSPAN spanned traffic. This is indicated by the configuration on Switch A, which includes the command monitor session 48 type erspan-source, specifying that it is sending ERSPAN traffic to a destination. The destination IP address for this traffic is set to 10.11.11.2, which corresponds to Host A’s interface VLAN12 IP address. Therefore, Host A, connected to Switch B, is the traffic analyzer, receiving the spanned traffic from Host B.

References := The explanation is based on the standard ERSPAN configuration practices where the source switch is configured with a session type of ‘erspan-source’ and the destination switch with ‘erspan-destination’. This information is typically covered in Cisco’s documentation on ERSPAN configurations and the Cisco Data Center Core Technologies (DCCOR) course materials.

Option D is the recommended method to configure the SAN boot when the storage system maps the source WWPN to a unique LUN. This method creates a SAN boot policy in which every initiator is mapped to a different target LUN, which ensures that each server boots from its own LUN and avoids any conflicts or errors. The other options are either incorrect or incomplete for the task. References:

To deploy a Cisco UCS C-Series Server with a single VIC 1455 integrated into a Cisco UCS Manager cluster without fabric extenders, the system should be reset to factory default settings using Cisco IMC. After the reset, VIC ports 1 and 3 should be attached to the Fabric Interconnects. This process ensures that the server is recognized by the UCS Manager and can be managed accordingly. The VIC 1455 supports multiple Ethernet and Fiber Channel over Ethernet speeds, making it suitable for direct connection to Fabric Interconnects1.

 EPLDs (Electronic Programmable Logic Devices) can be upgraded to enhance hardware functionality or resolve known issues without the need for hardware replacement. The upgrade process is disruptive as it requires the module to power down briefly during the upgrade. However, the system performs EPLD upgrades on one module at a time, minimizing the disruption to traffic through only one module at any given time.
