Cisco Implementing Cisco Data Center AI Infrastructure Sample Questions (Q51-Q56):

NEW QUESTION # 51
A Cisco AI environment requires synchronized packet processing timestamps across network devices for analytics accuracy. Which protocol should be deployed?

A. DNS
B. FTP
C. NTP
D. PTP

Answer: D

Explanation:
Precision Time Protocol (PTP) provides highly accurate clock synchronization required for latency-sensitive AI and analytics environments. NTP offers lower precision suitable for general IT systems. FTP and DNS are unrelated to time synchronization.

NEW QUESTION # 52
To support growing AI workload requirements, a regional medical practice is adding new X9516 X-Fabric module, UCS PCI Mezz cards, and UCS X580p PCIe nodes to their existing X-Series chassis. Which two administrative actions must be taken before the X-Fabric module is added to the chassis? (Choose two.)

A. Power down all IFMs in the chassis.
B. Disconnect cabling between IFMs and fabric interconnects.
C. Power down all blades that would connect to the X-Fabric modules.
D. Disconnect device connector.
E. Install UCS PCI Mezzanine cards in X-Series blades.

Answer: C,E

Explanation:
Before adding the X9516 X-Fabric module, the affected X-Series blades must be powered down because the X-Fabric connectivity path requires hardware installation and cannot be safely introduced while the connected compute nodes are running. The UCS PCI Mezzanine cards must also be installed in the blades so they can physically connect through the X-Fabric module to the X580p PCIe nodes for GPU expansion.

NEW QUESTION # 53
A data center administrator for a medium-sized manufacturing facility uses Intersight to perform unattended operating system installation on already discovered X-Series servers with server profiles assigned. Which set of prerequisites must be met for installing an operating system on a server in Cisco Mode?

A. adding an OS image to the software repository
adding a server configuration utility to the software repository
B. configuring a firmware policy
adding an operating system configuration file to the software repository
C. configuring a virtual KVM policy
adding a server configuration utility to the software repository
D. adding an OS image to the software repository
adding an operating system configuration file to the software repository

Answer: D

Explanation:
In Cisco Intersight, unattended operating system installation requires the OS installation image and the operating system configuration file to be available in the software repository. These files allow Intersight to boot the installer and apply the required unattended installation parameters to the assigned server profile.

NEW QUESTION # 54
What is a purpose of Cisco AI PODs?

A. to provide a turnkey, full-stack infrastructure for AI training, fine-tuning, and inferencing
B. to offer a flexible AI infrastructure focused on inferencing workloads with optional training capabilities
C. to enable AI lifecycle management through cloud-native software with hardware support limited to compute servers
D. to deliver modular AI hardware components that can be integrated with third-party software platforms

Answer: A

Explanation:
Cisco AI PODs are designed as integrated, validated full-stack infrastructure solutions that combine compute, networking, storage, and management capabilities to support AI training, fine- tuning, and inferencing workloads with faster deployment and operational consistency.

NEW QUESTION # 55
Refer to the exhibit. Users report delayed response times and network latency when running certain AI workloads on a specific Cisco UCS Intersight Managed Mode Domain. Based on the fault message and reported symptoms, which troubleshooting action must be taken first to address the network latency issues?

A. Examine the UCS fabric interconnect configuration for port-channel 11 on Fabric Interconnect B.
B. Review the pause frame counters for signs of congestion on Fabric Interconnect B Port 11.
C. Check the physical cabling and SFP+ transceivers on port 11 of switch B for potential hardware failures or incorrect configurations.
D. Review the AI workload configuration to optimize resource allocation (CPU, memory, GPU) for the affected applications.

Answer: C

Explanation:
The fault shows a receive error statistics threshold crossing on switch B port 11. Because receive errors on a physical interface commonly indicate cabling, transceiver, or physical-layer issues, the first troubleshooting step is to inspect the physical connection and SFP+ components on the affected port before investigating workload or higher-layer configuration.
