The series of commands provided in the exhibit are part of the process to update and activate firmware on a Cisco UCS server adapter. Theupdate firmwarecommand is used to update the firmware, while theactivate firmwarecommand, combined with theset-startup-onlyoption, schedules the activation of the firmware upon the next reboot of the adapter. This means that the new firmware will not be active immediately but will take effect after the adapter is rebooted, ensuring that the current operations are not disrupted.

The benefit of adding Cisco HyperFlex Hardware Acceleration Cards to a HyperFlex deployment is increased compression efficiency. These cards are PCIe devices that offload the compression and decompression operations from the CPU, resulting in higher performance and lower latency for most storage workloads. The cards also reduce the CPU utilization and power consumption of the HyperFlex nodes, enabling more resources for other applications. The other options (offline encryption acceleration, increased network throughput, and GPU acceleration) are not benefits of the HyperFlex Hardware Acceleration Cards.Reference: For more information on the HyperFlex Hardware Acceleration Cards, please refer to the following resources:

Cisco HyperFlex is a hyperconverged infrastructure solution that combines compute, storage, and networking in a software-defined platform. Cisco HyperFlex supports two hypervisors: VMware vSphere and RedHat KVM. VMware vSphere is a widely used virtualization platform that provides enterprise-class features and performance. RedHat KVM is an open source hypervisor that is integrated with the Linux kernel and offers scalability and flexibility. Cisco HyperFlex does not support Microsoft Hyper-V, OpenStack, or Citrix XenServer as hypervisors, although it can interoperate with them through other Cisco products or solutions.Reference: For more information on Cisco HyperFlex and its supported hypervisors, please refer to the following resources:

The statement that applies to a Cisco Nexus 5600 Series switch when performing a rollback is that errors are skipped when an atomic rollback type is triggered. An atomic rollback is a type of rollback that implements the checkpoint configuration only if no errors occur during the process. If any errors are encountered, the rollback is aborted and the running configuration is restored to its previous state. This ensures that the switch does not end up in a partially configured or inconsistent state. The other statements are not true because:

A user who is assigned to the network-operator user role cannot perform a rollback. The network-operator user role has read-only access to the switch and cannot modify the configuration. To perform a rollback, the user must have the network-admin or vdc-admin user role.

The configuration rollback functionality is not disabled when FCoE is enabled. The rollback feature is supported on all Cisco Nexus 5600 Series switches regardless of the FCoE configuration. However, some FCoE-related commands may not be rolled back due to dependencies or conflicts with other features.

A system checkpoint is not generated automatically when the running configuration is saved to NVRAM. A system checkpoint is a predefined checkpoint that contains the last saved configuration of the switch. A system checkpoint is created or updated only when the user explicitly saves the running configuration to the startup configuration using the copy running-config startup-config command or its alias, copy run start.Reference: For more details on how to configure and use the rollback feature on a Cisco Nexus 5600 Series switch, please refer to the following resources:

The statement that is true about the impact of a rolling EPLD upgrade on a Cisco MDS 9000 Series Switch is that only the modules that are being upgraded are disrupted. A rolling EPLD upgrade is a type of EPLD upgrade that allows the user to upgrade one or more modules in a switch without affecting the rest of the modules. The rolling EPLD upgrade requires a module reload for each module that is being upgraded, which causes a temporary disruption of traffic and services on that module. However, the other modules in the switch continue to operate normally and do not require a reload. The other statements are not true because:

All modules on the switch are not disrupted. As explained above, only the modules that are being upgraded are disrupted, while the other modules are unaffected by the rolling EPLD upgrade.

An EPLD upgrade is not nondisruptive. An EPLD upgrade is a process that updates the firmware of the electrical programmable logic devices (EPLDs) that provide hardware functionalities in the switch modules. An EPLD upgrade always involves a module reload, which causes a disruption of traffic and services on that module. However, the disruption can be minimized by using the hitless or non-disruptive EPLD upgrade modes, which preserve the forwarding state and configuration of the module during the reload.

The upgrade cannot be performed from the standby supervisor module. The EPLD upgrade process requires the supervisor module to be in active mode before it can be upgraded. The standby supervisor module must be switched to active mode manually or automatically before the upgrade can begin.Reference: For more information on how to perform a rolling EPLD upgrade on a Cisco MDS 9000 Series Switch, please refer to the following resources:

The command that reduces the amount of time it takes to complete the ISSU on a Cisco Nexus 7000 series switch that has dual supervisor modules and two I/O modules is install all kickstart <image>system<image>parallel. This command performs a parallel upgrade of the kickstart and system images on all modules, which reduces the downtime and speeds up the ISSU process. The other commands (install all epld bootflash:<image> and install all kickstart<image>system<image>) do not perform a parallel upgrade and take longer to complete the ISSU.Reference: For more information on how to perform an ISSU on a Cisco Nexus 7000 series switch, please refer to the following resources:

: Two statements that are true about the process of performing an EPLD upgrade on a Cisco MDS 9000 series Switch are:

If an upgrade is interrupted, the upgrade continues after a connection is restored. This means that the EPLD upgrade process is resilient to network or power failures and can resume from where it left off once the connection is reestablished.

The upgrade can be performed from the standby supervisor module. This allows the active supervisor module to continue to provide management and control functions while the EPLD upgrade is in progress. The standby supervisor module can also take over the active role if needed during the upgrade.

The other statements are not true because:

The active supervisor cannot be upgraded. The EPLD upgrade process requires the supervisor module to be in standby mode before it can be upgraded. The active supervisor module must be switched to standby mode manually or automatically before the upgrade can begin.

Modules do not need to be online to be upgraded. The EPLD upgrade process can upgrade modules that are offline or powered down as well as modules that are online. The offline modules are upgraded when they are brought online or powered up.

The upgrade process disrupts all modules that are being upgraded. The EPLD upgrade process requires a module reload for each module that is being upgraded, which causes a temporary disruption of traffic and services on that module. The disruption can be minimized by using hitless or non-disruptive EPLD upgrade modes, which preserve the forwarding state and configuration of the module during the reload.Reference: For more details on how to perform an EPLD upgrade on a Cisco MDS 9000 series Switch, please refer to the following resources:

The statement that is true about the behavior of multiple roles applied to a user on the Cisco MDS 9000 Series Switch is that access to a command takes priority over being denied access to a command. This means that if a user has multiple roles assigned and one of the roles grants access to a command while another role denies access to the same command, the user will be able to execute the command. The access permission overrides the deny permission in case of a conflict. The other statements are not true because:

Any commands that have conflicting settings between roles are not denied. As explained above, the access permission prevails over the deny permission in case of a conflict.

The first role assigned does not take precedence over subsequent roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied.

The last role assigned does not take precedence over previous roles. The order of role assignment does not affect the command authorization. All roles assigned to a user are evaluated together and the most permissive setting is applied.Reference: For more information on how to configure and manage roles on the Cisco MDS 9000 Series Switch, please refer to the following resources:

The backup operation type that does not include the Preserve Identities feature is the logical configuration. This type of backup includes the settings and configurations that are logically defined within the Cisco UCS Manager, such as service profiles, policies, and management settings. However, it does not include the unique identifiers or 'identities' such as MAC addresses, WWN pools, and UUIDs, which are preserved in other types of backups like system configuration and full state.
