Question # 13

A solutions architect must implement a monitoring strategy for a new AI/ML data center infrastructure built on Cisco UCS X-Series servers with NVIDIA H100 GPUs, managed by Cisco Intersight. The main objectives are to gain deep visibility into GPU performance, identify resource bottlenecks for AI training workloads, and ensure the overall health and efficiency of the compute environment.

Which Cisco Intersight capability is most critical for effectively monitoring this AI-centric infrastructure?

Options:

A.  

Analyze feature automating the deployment and scaling of AI application containers and their underlying Kubernetes infrastructure, which reduces manual monitoring efforts

B.  

integration with Cisco Nexus Dashboard for advanced network flow analytics and anomaly detection across the data center fabric, which ensures high-speed data transfer between GPU nodes

C.  

basic server health reporting, which is limited to CPU and memory statistics, and requires specialized third-party tools for any GPU-specific performance monitoring or diagnostics

D.  

comprehensive health and performance monitoring, which provides real-time telemetry data for UCS servers, including granular metrics for NVIDIA GPUs, which enables direct insights into AI workload execution

Question # 14

A network team is configuring quality of service (QoS) for RoCEv2 traffic on a VXLAN fabric. The team must ensure that congestion notification packets (CNP) generated by storage targets are never dropped in the network, as these packets are critical for congestion control feedback.

How must CNP packets be handled in the QoS configuration to ensure reliable delivery?

Options:

A.  

Apply traffic shaping to CNP packets to prevent them from causing additional congestion.

B.  

Classify CNP packets to a high-priority queue using their DSCP marking.

C.  

Configure CNP packets to use the same queue as regular RoCEv2 data traffic.

D.  

Enable Priority Flow Control specifically for CNP packets on a dedicated CoS value.

Question # 15

A customer is deploying a new AI fabric with all new NVIDIA GPUs and must verify the performance between the nodes in the network.

Which tool must be used to validate the customer benchmarks?

Options:

A.  

NCCL

B.  

Spirent

C.  

iPerf

D.  

IXIA

Question # 16

How does RAG enhance the capabilities of LLMs?

Options:

A.  

by removing the data preparation and cleaning step

B.  

by removing inherent biases from LLM outputs

C.  

by providing access to proprietary data

D.  

by retaining the LLM by altering its core parameters

Question # 17

An engineer must monitor congestion, flow latency, and traffic drops using Cisco Nexus Dashboard and chooses to use the Traffic Analytics feature.

Which Nexus Dashboard feature is automatically disabled when Traffic Analytics is enabled?

Options:

A.  

Delta Analysis

B.  

Flow Telemetry

C.  

Connectivity Analysis

D.  

SNMP Traps

Question # 18

A network architect designs connectivity for a new Cisco AI POD operating in Intersight Managed Mode. To ensure high availability and aggregate bandwidth for external network traffic, a port channel must be established using multiple 100 GbE uplink ports on the fabric interconnects to connect to the upstream core switch infrastructure.

Which specific policy, applied through the domain profile, must be modified to define and configure this port channel on the fabric interconnects for the desired uplink connectivity?

Options:

A.  

LAN connectivity policy

B.  

port policy

C.  

network connectivity policy

D.  

Ethernet network group
