NEW QUESTION # 27
An upgrade of protected RPMs from the Bash shell did not take effect. Which action is required for the changes to take effect?
- A. Restart the Bash shell.
- B. Reload the switch.
- C. Upgrade the RPMs from the Guest shell.
- D. Disable and reenable the Bash feature.
Answer: B
NEW QUESTION # 28
Refer to the exhibit.
The script fails to bring up Ethernet 1/2 when Ethernet 1/1 goes down. Which change enables the script to run as intended?
- A. Set the port VLAN
- B. Add an action to configure the terminal
- C. Configure an enable action
- D. Include an action to manually shut down Ethernet 1/1
Answer: B
Explanation:
Add an action to configure the terminal is the required fix because the automation failure is caused by execution context, syntax, or resource state around The, Ethernet, Set. On Cisco Nexus switches, automation is not a single feature; EEM policies, CLI actions, Guest Shell Linux commands, REST payloads, and scheduled jobs are evaluated by different subsystems. A script can fail even while the switch itself has connectivity or the command works interactively. The selected answer supplies the missing requirement, such as the correct event/action, DNS or resource setting, API URI, payload format, feature enablement, or reboot needed for a Guest Shell change to take effect. The other choices address adjacent features but do not satisfy the failing subsystem. After applying the fix, the engineer should verify the policy registration, job result, API response code, or Guest Shell runtime state and confirm that the intended command is no longer blocked or silently ignored.
NEW QUESTION # 29
Refer to the exhibit.
A network engineer configures an EEM script to get a syslog notification after a configuration change. This message appears when the engineer must make a new configuration to this switch. Which configuration did the engineer neglect to apply in the script for it to function properly?

NEW QUESTION # 32
The script fails to convert a JSON variable into a Python dictionary. Which action resolves the issue?
- A. Fix the JSON syntax by modifying "attribures" to "attribures":
- B. Define a json_output as a YAML object, yaml json_output
- C. Invoke a function yaml.loads(json._output ,decoder_"json")
- D. Use a json.dumps(json_output) function
Answer: A
Explanation:
Fix the JSON syntax by modifying "attribures" to "attribures": is the required fix because the automation failure is caused by execution context, syntax, or resource state around The, JSON, Python, Use. On Cisco Nexus switches, automation is not a single feature; EEM policies, CLI actions, Guest Shell Linux commands, REST payloads, and scheduled jobs are evaluated by different subsystems. A script can fail even while the switch itself has connectivity or the command works interactively. The selected answer supplies the missing requirement, such as the correct event/action, DNS or resource setting, API URI, payload format, feature enablement, or reboot needed for a Guest Shell change to take effect. The other choices address adjacent features but do not satisfy the failing subsystem. After applying the fix, the engineer should verify the policy registration, job result, API response code, or Guest Shell runtime state and confirm that the intended command is no longer blocked or silently ignored.

NEW QUESTION # 39
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. Reset the port for FC ID 0x970209 and FC ID 0x9700c2 to log in to the fabric.
- B. Reactivate the zoneset.
- C. Reconfigure the initiator and the target to be in the same zones.
- D. Reset the port for FC ID 0x970102 and FC ID 0x970200 to log in to the fabric.
Answer: C
NEW QUESTION # 40
A request to activate the port security database is rejected. Which action do you perform to investigate the cause of the issue?
- A. Enable the auto-learning feature.
- B. Find conflicting entries between the active and configuration databases.
- C. Use the force option to identify rejected devices.
- D. Verify that devices are fully attached to the active database.
Answer: C
Explanation:
Use the force option to identify rejected devices is the required SAN-side correction. In Cisco storage fabrics, symptoms such as isolated ports, missing targets, failed zone merges, vFC down state, or inaccessible LUNs are rarely solved by changing a random endpoint setting. The engineer must validate the FC control-plane dependency associated with port security: VSAN assignment, trunk allowance, FSPF parameters, fcdomain uniqueness, NPIV support, NPV uplink behavior, DCBX/LLDP negotiation, and active zoning. The selected answer is the one that restores that dependency. Other choices may be valid operational commands in a different failure, but they do not address the precise point where fabric membership or access control is broken. Cisco guidance is to verify the active database and the operational database separately because a configured object is not necessarily active in the fabric. Post-remediation checks should include interface state, VSAN status, FLOGI/PLOGI, zoneset membership, and target visibility from the initiator.
NEW QUESTION # 41
Refer to the exhibit.
An EEM applet must be used to run a Python file called " Config " that enables all administratively disabled interfaces. The script fails to run as expected. Which command resolves the issue?
- A. action 1.0 cli local python Script_1.py
- B. action 1.0 cli local tclsh Config
- C. action 1.0 cli local tclsh Script_1
- D. action 1.0 cli local python Config.py
Answer: D
Explanation:
The selected option, action 1.0 cli local python Config.py, is correct for the automation path described. Cisco NX-OS requires precision in EEM applets, scheduler jobs, Guest Shell operations, and REST/NX-API syntax.
The affected element is EEM; therefore, the fix must be applied to the component that actually executes the action. For EEM, that means a valid event detector and explicit actions, with event-default when the matched CLI command should continue. For Guest Shell and Bash, DNS, proxy, resource allocation, and reboot behavior are local to the Linux container. For REST calls, the class name, method, authentication, and XML
/JSON structure must match the APIC or NX-OS object model. The distractors usually change the switch globally or alter an unrelated command. Cisco DCIT automation troubleshooting confirms the fix by checking the returned error, then rerunning the exact job, script, or API operation in the same context.

NEW QUESTION # 47 
Refer to the exhibits. An engineer is implementing the SAN based on the Cisco MDS 9000 Series Switches.
When operating the environment, the engineer encounters the error shown. Which action resolves the issue?
- A. Enable VSAN 101 on the peer MDS 2 switch fabric interconnect
- B. Configure the port security feature on the MDS-1 switch
- C. Copy VSAN 101 to the fabric binding database on the MDS-1 switch
- D. Add the World Wide Name of the neighboring switch to the MDS-1 switch
Answer: D
Explanation:
The selected resolution is Add the World Wide Name of the neighboring switch to the MDS-1 switch because the failure is in the Fibre Channel/FCoE control path around MDS, VSAN, fabric interconnect, port security, fabric binding. Cisco MDS and Nexus platforms separate configuration from operational state: a VSAN, zone, vFC binding, device alias, or port-security entry can exist in configuration but still fail if it is not active, correctly merged, or allowed on the link. The correct option addresses the fabric condition that prevents communication. The incorrect options are technically adjacent but would not repair the specific dependency; for example, changing unrelated databases or resetting ports without correcting policy leaves the same failure to recur. Cisco SAN troubleshooting therefore starts with port role and VSAN checks, then confirms fabric services such as fcdomain, FSPF, zoning, fabric binding, and name-server information. The expected validation is that the port becomes operational, the initiator and target appear in the appropriate databases, and permitted zone members can communicate.
NEW QUESTION # 48 
Refer to the exhibit. An engineer discovered a VFC interface in a down state on a Cisco Nexus Switch. Which action resolves the problem?
- A. Change the cable between the switch and the server
- B. Update the CNA firmware and driver versions
- C. Reset the Cisco Nexus port toward the file server
- D. Modify the fip keepalive message time to 30 seconds
Answer: B
Explanation:
The correct answer is Update the CNA firmware and driver versions. Cisco MDS and Nexus SAN troubleshooting is driven by fabric state: the host and target must be in the correct VSAN, must complete FLOGI/PLOGI where applicable, and must be permitted by active zoning, fcdomain, FSPF, NPV/NPIV, or port-security policy. This question focuses on firmware, Cisco Nexus, so the selected action fixes the dependency that prevents the initiator, target, or inter-switch link from becoming usable. Cisco documentation emphasizes checking VSAN membership, active zonesets, correct port mode, fabric binding, device-alias consistency, and the relevant FC databases before changing unrelated server settings. The distractors either target a different database, use the wrong port role, or would not cause the observed Fibre Channel state to change. After the fix, the engineer should confirm the interface state, FLOGI database, name-server entries, zoneset activation, and successful initiator-to-target reachability with tools such as fcping or fabric show commands.
