Question 8

Refer to the exhibit. A SAN engineer connected two Cisco MDS 9000 Series Switches using the fc1/1 interface. The interface is a trunk for VSANs 10 and 11. After the port was connected and configured, a syslog message was displayed stating that VSAN 11 is isolated because of a zone merge failure, but VSAN 10 was working as expected. Because VSAN 10 is used for the production network, its traffic must be uninterrupted by maintenance activities. Additionally, the SAN fabric is expected to grow in the future, so the available TCAM space on the switches must be saved. Which command set resolves the issue and preserves the available TCAM space?

A. MDS-2# zoneset export interface fc1/1 vsan 11
MDS-2(config)# int fc1/1 ; no switchport trunk allowed vsan 11
MDS-2(config-if)# switchport trunk allowed vsan add 11 B. MDS-2(config)# zone smart-zoning enable vsan 11
MDS-2# zoneset export interface fc1/1 vsan 11
B,
MDS-1(config)# zone smart-zoning enable vsan 11
MDS-1# zoneset import interface fc1/1 vsan 11 C. MDS-1# zoneset import interface fc1/1 vsan 11
MDS-1(config)# zoneset distribute full vsan 11
MDS-1(config)# int fc1/1 ; shutdown ; no shutdown

Question 12

An engineer is troubleshooting issues in Cisco UCS Director. Drag and drop the possible causes from the left onto the correct issues on the right.

Discussion 0

Correct Answer:

Explanation:
the drag-and-drop mapping shown in the answer key is the appropriate UCS remediation because the symptom maps to a specific managed object rather than a generic server failure. Cisco UCS abstracts hardware through service profiles and policies; therefore, issues involving UCS must be corrected where UCS Manager programs the adapter, boot target, firmware, management certificate, pool qualification, or fabric interconnect state. The selected answer restores that programming path. The other options may appear plausible, but they do not correct the object that UCS uses to derive operational state. For example, boot failures require the correct vHBA/iSCSI target and LUN policy, discovery issues require the proper physical and management path, and firmware failures require the documented recovery action for the failed FSM stage. The correct validation is to inspect the associated fault, confirm inventory acknowledgment, verify the policy under the service profile or equipment tree, and then recheck boot or connectivity behavior after the FSM completes.

Question 13

The VXLAN fabric is deployed with this configuration:
#The VLAN 50 interface has no IP address on VTEP1 and VTEP4.
#The VLAN 100 interface has no IP address on VTEP2 and VTEP3.
# nve1 interface is configured on all VTEPs.
Host A experiences timeouts when attempting to ping host B. Which set of actions allows host A to reach host B7

A. On VTEP1, associate VNI 50000 to Test Telco VRFOn VTEP4, associate VNI 50000 to Test Telco VRF. B. On VTEP2, associate VNI 55000 to Test Telco VRF.
On VTEP4, associate VNI 50000 to Test Telco VRF. C. On VTEP2, associate VNI 30000 to Test Telco VRF
On VTEP4, associate VNI 20000 to Test Telco VRF D. On VTEP1, associate VNI 30000 to Test_ Telco VRF.
