An engineer must upgrade all components in a Cisco UCS domain to the same package version, but the upgrade process fails to complete.
Which set of Auto Install actions resolves the problem?
- A . Install Infrastructure Firmware, then Install Server Firmware.
- B . Install infrastructure Firmware, then Install Hypervisor Firmware.
- C . Install Hypervisor Firmware, then Install Infrastructure Firmware
- D . Install Server Firmware, then Install Infrastructure Firmware
You have an ACI environment with three APICs, two spine switches, and four-leaf switches. You wipe and reboot all APICs first then leaf and spine switches one-by-one and successfully go through the Initial Setuo dialogue on the APIC 1 CIMC KVM console. When you log in to the APIC1 WebGUI, you notice that you do not see any directly connected leaf switches being discovered under Fabric > Inventory > Fabric Membership.
What is the cause of the issue?
- A . The leaf nodes were not erased properly, which caused a fabric parameters mismatch with the APIC1.
- B . Rebooting the APICs and the leaf and spine switches after wiping them is not required.
- C . You forgot to enter the TEP Pool value during the Initial Setup dialogue on APIC1.
- D . The same Fabric Name value should be used before after wiping all devices.
Refer to the exhibit.
An engineer performs a POST operation using REST API on the Cisco Nexus switch to retrieve a managed object, but the operation fails.
Which configuration resolves the issue?
- A . https://172.16.10.1/api/node/mo/uni/tn-Test1.xml? rsp-subtree=full&rsp-prop-include=config-only
- B . icurl -k-v https://172.16.10.1/api/node/mo/uni/tn-Test1.xml? rsp-subtree=modified=config-only
- C . https:/172.16.10.1/api/node/mo/uni/tn-Test1.xml? rsp-subtree=modified=config-only
- D . icurl -k -v https://172.16.10.1/api/mo/uni.xml?rsp-subtree=no<fv Tenant name="Test1" />
Refer to the exhibit.
A certificate is implemented on the security configuration on the Cisco ACI controller. A customer receives a "Connection Not Secure" error in a browser every time the customer logs in to the Cisco APIC GUI.
Which action resolves the issue?
- A . Include a private key with the certificate.
- B . Use a browser that supports keys of 2048 bits.
- C . Configure a corporate certificate authority for the certificate.
- D . Add a 1536-bit key to the APIC GUI.
Refer to the exhibit.
RBAC is configured on the MDS switch for a new SAN administrator engineer to work on the FSPF configuration. However, after the configuration is applied the engineer who was assigned the FSPF_Admin role cannot perform any configuration changes.
Which action resolves the issue?
- A . Write rule 2 before rule 1
- B . Remove rule 1 from the role
- C . Configure the switch license for RBAC
- D . Reload the switch

Which statement about interface Ethernet 1/11 is true?
- A . The interface is working correctly and fully operational, but it is not in use.
- B . The interface policy is misconfigured.
- C . “out-of-service” is the default interface status in ACI.
- D . “out-of-service” indicates that no service graph is in use for this interface.
An engineer is troubleshooting a fabric discovery failure.
Which two requirements must an engineer verify about switch connectivity to solve the problem? (Choose two.)
- A . A Cisco APIC must be attached to a spine node only.
- B . A Cisco APIC must be attached to leaf nodes.
- C . Spine nodes must connect to other spine nodes.
- D . A Cisco APIC must be dual-attached to two separate spine nodes.
- E . Leaf nodes must connect to spine nodes only.
Refer to the exhibit.
The initiator that has FC ID 0x970102 fails to communicate with the target that has FC ID 0x970200.
What action resolves the issue?
- A . Reconfigure the initiator and the target to be in the same zones.
- B . Reactivate the zoneset.
- C . Reset the port for FC ID 0x970102 and FC ID 0x970200 to log in to the fabric.
- D . Reset the port for FC ID 0x970209 and FC ID 0x9700c2 to log in to the fabric.
