Accepted Answer

Add a Cisco MDS 9148S Fibre Channel switch and connect it to the Fabric Interconnect via FC uplinks.. The Cisco UCS Mini with a single Fabric Interconnect 6324 does not have native Fibre Channel ports; it only supports Ethernet uplinks. To connect to an existing Fibre Channel SAN, an external Fibre Channel switch (such as the Cisco MDS 9148S) must be added, and the Fabric Interconnect connects to it via FC uplinks, which are typically configured as unified ports. This allows the UCS Mini to leverage the MDS switch for Fibre Channel connectivity, as the 6324 itself cannot directly terminate Fibre Channel links.

Answer

Enable NPV mode on the Fabric Interconnect to connect to the SAN.

Answer

Install a Fibre Channel module in the Fabric Interconnect.

Answer

Configure the uplink Ethernet ports as unified ports to support Fibre Channel.

Question 2

Which THREE conditions must be met before a UCS Fabric Interconnect can be part of a port channel? (Select THREE.)

Accepted Answer

All ports must be on the same side of the switch (either all uplink or all server-facing).. To form a port channel on a UCS Fabric Interconnect, three conditions must be met. First, all ports must be on the same side of the switch (all uplink or all server-facing) to ensure consistent forwarding behavior (Option B). Second, ports should be configured as admin down until the port channel is formed to avoid traffic disruption and misconfiguration (Option C). Third, all ports in the port channel must have the same speed and duplex settings (Option E). Option D is incorrect because a vPC domain is not required for a port channel on a single Fabric Interconnect; vPC is used for multi-chassis LAGs across two FIs, not for a simple LAG on one FI.

Answer

Ports should come from different FEX modules for redundancy.

Answer

The ports must belong to the same virtual port channel (vPC) domain.

Question 3

A financial services company operates a Cisco UCS 6454 Fabric Interconnect cluster with two FI-A and FI-B, connected to multiple UCS B-Series blades. The environment uses UCS Manager 4.2(1a). Recently, the company migrated to a new storage array connected via Fibre Channel. The storage team configured 8 virtual SANs (VSANs) and created a new VSAN 400 for a critical application. After the migration, the application server running on a UCS blade cannot discover the storage LUNs. The server's vHBA is configured correctly with the proper WWPN, and the zone set is active on the SAN switches. The engineer checks the UCS Manager and sees that the vHBA is down. Which action should the engineer take to resolve the issue?

Accepted Answer

Verify that the uplink Fibre Channel ports on the fabric interconnects are configured to allow VSAN 400.. A vHBA being down typically indicates no Fibre Channel connectivity. The most likely cause is that the FC uplink ports on the fabric interconnects are not configured to allow VSAN 400. Option A is incorrect because upgrading UCS Manager is not a standard troubleshooting step without evidence of a specific bug. Option C is incorrect because rebooting the server blade does not resolve VSAN configuration or uplink port issues. Option D is incorrect because the vHBA WWPN is already correct, and recreating it would not address the lack of connectivity.

Answer

Upgrade UCS Manager to the latest version to fix a known bug.

Answer

Reboot the server blade to force re-discovery of the storage.

Answer

Recreate the vHBA in the service profile with a different WWPN.

Question 4

An administrator is configuring a UCS service profile for a blade that will run a database workload. The requirements: high network throughput and redundancy. Which TWO vNIC features should be enabled in the service profile?

Accepted Answer

Enable vNIC teaming (active-backup or LACP).. vNIC teaming (e.g., active-backup or LACP) provides redundancy, and MTU jumbo frames increase throughput by reducing overhead.

Answer

Enable VLAN trunking on the vNIC.

Answer

Increase the number of receive queues.

Answer

Enable fabric failover on the vNIC.

Question 5

An engineer is deploying a new UCS chassis with two Fabric Interconnects. The design requires that server traffic can fail over to the secondary FI if the primary FI fails, without requiring any changes to the server's network configuration. Which technology must be enabled on the uplink ports of the Fabric Interconnects to the upstream switches to ensure transparent failover of server traffic?

Accepted Answer

Enable pin groups with 'failover' mode on the server ports.. Pin groups with 'failover' mode enable transparent server traffic failover by pinning server vNICs to a specific Fabric Interconnect (FI) and automatically repinning them to the secondary FI upon primary FI failure, without requiring any changes to the server's network configuration. This ensures that the server's MAC and IP addresses remain active on the secondary FI, maintaining connectivity without manual intervention.

Answer

Configure a virtual PortChannel (vPC) between the Fabric Interconnects and upstream switches.

Answer

Apply QoS policies to prioritize failover traffic.

Answer

Implement Private VLANs on the uplink ports to isolate traffic.

Question 6

A UCS administrator notices that a service profile associated with a vNIC template that uses 'fabric failover' is not failing over to the secondary Fabric Interconnect when the primary link goes down. The vNIC template is set to 'fabric failover' enabled, and both Fabric Interconnects are in the same VLAN. What is the most likely cause?

Accepted Answer

The 'Primary Fabric' setting is not defined in the vNIC template.. When 'fabric failover' is enabled on a vNIC template, the UCS Manager requires the 'Primary Fabric' setting to be explicitly defined to determine which Fabric Interconnect (FI-A or FI-B) should be the active path. Without this setting, the system cannot properly orchestrate the failover behavior, causing the vNIC to remain pinned to the primary FI even when its link goes down. This is a common misconfiguration because the 'fabric failover' checkbox alone does not imply a primary fabric assignment.

Answer

The server is pinned to the primary Fabric Interconnect via a pin group.

Answer

The MTU size on the secondary Fabric Interconnect is set to 1500 instead of 9000.

Answer

The 'MAC Address' policy is set to 'pool-based' instead of 'static'.

Question 7

An engineer is configuring a UCS server profile for a database application that requires low latency. The server will use a Cisco UCS VIC 1340 adapter. Which vNIC placement policy should be selected to minimize latency?

Accepted Answer

Assigned. The Assigned vNIC placement policy binds each vNIC to a specific physical port on the Cisco UCS VIC 1340 adapter, ensuring deterministic traffic flow and predictable latency. For low-latency database applications, this eliminates the variability introduced by dynamic placement, allowing the engineer to align vNICs with the most direct PCIe path to the CPU or memory.

Answer

Any

Answer

Default

Answer

Round-Robin

Question 8

Which TWO statements correctly describe the use of Cisco UCS Manager service profiles for server deployment?

Accepted Answer

Service profiles decouple server identity from hardware, enabling rapid provisioning.. Service profiles decouple the logical server identity (UUID, MAC addresses, WWPNs) from the physical hardware. This allows an administrator to rapidly provision or repurpose a server by simply associating the profile with a different blade or rack server, without reconfiguring the OS or SAN/NIC settings. This abstraction is the core value of Cisco UCS Manager for scalable, stateless computing.

Answer

Service profiles can only be applied to servers of the same model.

Answer

A service profile can be associated with multiple servers simultaneously.

Answer

Service profiles are stored locally on the server's boot drive.

Question 9

Which THREE components are required to configure a Cisco UCS Direct-attached storage environment using SAS expanders?

Accepted Answer

SAS cables connecting the storage enclosure to the server's storage controller.. In a Cisco UCS Direct-attached storage environment using SAS expanders, SAS cables are required to physically connect the storage enclosure to the server's storage controller (typically an LSI-based SAS HBA). This direct cabling enables the SAS protocol to carry SCSI commands and data between the server and the drives without any intervening network fabric.

Answer

Fibre Channel over Ethernet (FCoE) uplinks from the storage enclosure to the Fabric Interconnect.

Answer

Fibre Channel switch for SAN connectivity.

Question 10

Refer to the exhibit. A UCS administrator has configured vNIC templates as shown. Both Fabric Interconnects have identical uplink configurations. The vNIC templates have 'Failover: Enabled'. However, when Fabric Interconnect A fails, servers using vNIC-A do not fail over to Fabric Interconnect B. What is the most likely cause?

Accepted Answer

The server's service profile does not include a secondary vNIC for Fabric B.. The server's service profile must include both a primary vNIC (for Fabric Interconnect A) and a secondary vNIC (for Fabric Interconnect B) to enable failover. The 'Failover: Enabled' setting on the vNIC template only allows the vNIC to use the other fabric's uplink if a secondary vNIC is explicitly defined in the service profile; without it, the vNIC is pinned to its original fabric and cannot fail over.

Answer

A pin group is configured that forces traffic to Fabric Interconnect A.

Answer

The native VLAN (10) is not allowed on Fabric Interconnect B's trunk.

Answer

The uplink interfaces are configured with 'spanning-tree port type edge trunk', which blocks failover traffic.
