Cisco Implementing Cisco Data Center AI Infrastructure Sample Questions (Q73-Q78):

NEW QUESTION # 73
How does RAG enhance the capabilities of LLMs?

A. by providing access to proprietary data
B. by removing inherent biases from LLM outputs
C. by removing the data preparation and cleaning step
D. by retaining the LLM by altering its core parameters

Answer: A

Explanation:
RAG enhances LLMs by retrieving relevant external or proprietary information at generation time and using that context to produce more accurate, current, and domain-specific responses without changing the model's core parameters.

NEW QUESTION # 74
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 an operating system configuration file 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 a server configuration utility to the software repository

Answer: A

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 # 75
Which function is provided through natural language processing?

A. annotation of data transmission protocols for device authorization
B. automated conversion of spoken or written content into structured data
C. filtration of duplicate entries from transaction records
D. compression of large configuration files for storage efficiency

Answer: B

Explanation:
Natural language processing enables systems to interpret, process, and transform human language from spoken or written inputs into structured data that applications can analyze, search, classify, or use for automation.

NEW QUESTION # 76
An engineer must configure dynamic load balancing (DLB) on a Cisco Nexus 9000 Series Switch AI fabric using a CLI. Which configuration must be implemented for only the odd-numbered interfaces?

A. Exclude the desired interfaces from DLB with the interface level configuration of no dlb-interface.
B. Under the relevant interface-level configuration, add the keyword dlb-interface.
C. Create a DLB hardware profile and include the list of desired interfaces.
D. Create a QoS policy that enables DLB and apply that policy to the relevant interfaces.

Answer: B

Explanation:
Dynamic load balancing is enabled on the selected Cisco Nexus 9000 interfaces by applying the interface-level dlb-interface command. For this deployment requirement, the command is applied only to the odd-numbered interfaces that participate in the DLB configuration.

NEW QUESTION # 77
A network engineer is deploying an AI training fabric using Cisco Nexus switches with RoCEv2 enabled. During testing, packet drops occur when traffic bursts exceed buffer capacity. Which feature should be configured to minimize congestion and improve lossless Ethernet performance for GPU traffic?

A. DHCP Snooping
B. Priority Flow Control
C. BPDU Guard
D. Storm Control

Answer: B

Explanation:
Priority Flow Control (PFC) allows selective pausing of traffic classes during congestion, which is critical for RoCEv2 environments carrying GPU-to-GPU communication. AI workloads are highly sensitive to packet loss and retransmissions. BPDU Guard and DHCP Snooping are security features, while Storm Control only limits broadcast or multicast traffic and does not create lossless behavior for RDMA traffic.

NEW QUESTION # 78
