Question 1 of 291

A mission-critical server is connected to site A. Connectivity to this server is lost from site B because the MAC route is missing in the OTV VDC of the Cisco Nexus 7000 in site B due to MAC aging.

Which action allows the flooding of the unknown unicast MAC on the Nexus 7000 in the OTV VDC?

Answer choices
Show answer

Correct answer: C

To allow the flooding of unknown unicast MAC on the Nexus 7000 in the OTV VDC, you should use the otv flood mac command. This command enables selective unicast Overlay Transport Virtualization (OTV) flooding for a given MAC address. The configuration is specifically designed to address scenarios where unknown unicast traffic needs to be selectively flooded based on the MAC address, thus addressing the problem of MAC aging and connectivity loss.

Question 2 of 291

The Cisco Nexus switch is connected to a peer switch that is not running Cisco NX-OS. The switches are connected using port channel and are experiencing packet loss. Which action should be performed on the Cisco Nexus switch ports to resolve this issue?

Answer choices
Show answer

Correct answer: C

When a Cisco Nexus switch is connected to a peer switch that is not running Cisco NX-OS and packet loss occurs over a port channel, the correct action is to turn off LACP graceful-convergence. Disabling LACP graceful-convergence helps ensure compatibility and stability when interfacing with non-NX-OS devices, as LACP graceful-convergence can cause issues with handling port-channel negotiations with such devices that do not fully support NX-OS LACP features.

Question 3 of 291

Cisco UCS Manager raises a critical error message that indicates that the system has overlapping Ethernet and FCoE VLANs. All of the Ethernet traffic on the overlapping VLANs drops. Which action resolves the issue?

Answer choices
Show answer

Correct answer: C

When overlapping VLANs are detected between Ethernet and FCoE, it is essential to modify the FCoE VLAN to avoid conflicts and ensure traffic flows correctly. This action separates the Ethernet VLAN and FCoE VLAN, thus preventing any overlap and resulting in normal traffic flow for both types of traffic.

Question 4 of 291

An upgrade of protected RPMs from the Bash shell does not take effect. Which action resolves this issue?

Answer choices
Show answer

Correct answer: B

To resolve the issue of an upgrade of protected RPMs from the Bash shell not taking effect, it is necessary to reload the switch. Upgrading or downgrading protected RPMs requires a system reload for the changes to take effect. Simply restarting the Bash shell or disabling and re-enabling the Bash feature will not apply the upgrade to protected RPMs.

Question 5 of 291

A network engineer is implementing the Cisco ACI Fabric and notices that the Leaf-1 switch is registered, has an assigned name, but is displayed as inactive in the APIC. After further investigation, it became clear that the leaf switch was recently moved from another Cisco ACI environment. Which action resolves the problem?

Answer choices
Show answer

Correct answer: A

When a Cisco ACI Leaf switch is moved from one environment to another, residual configurations or settings from the previous environment can cause issues in the new setup. A clean reload ensures that any previous configurations, policies, and settings are completely removed, allowing the switch to register correctly and operate as expected in the new environment. This step is crucial to resolve inconsistencies and conflicts that might prevent the switch from becoming active in the APIC.

Stories from the certified

Charles Sirois
Canada
As this was my first certification exam, I was understandably nervous about what to expect. These study materials made the preparation process much easier, and many of the questions closely reflected those on the actual exam.
Lance Chambers
United States
Wasted about a month going through the free dump sites scattered all over reddit, half the answers were wrong and the other half were for a version of the exam that doesn't even exist anymore. Eventually gave in and paid the small fee here, and the difference was night and day.
Alisha Kelly
Italy
Honestly, I had already gone through the official documentation quite thoroughly, but still didn't feel fully confident going in. This helped things finally click for me. I realized I knew the material, but just hadn't connected all the pieces yet.
Casper Claassen
Netherlands
Used this along with Microsoft Learn and the combo worked really well. The practice questions made the stuff I'd read actually stick. Passed first attempt, no complaints from me.
Gabriele Ghesla
Italy
The content is accurate and clearly presented, and it's more affordable than competitors. The team has been incredibly responsive whenever I've had an issue, and they've been open to small changes that improve the platform.
