Accepted Answer

RF3. Replication Factor 3 (RF3) stores three copies of data across the cluster, offering protection against two concurrent node failures.

Answer

RF1

Answer

RF2

Answer

RF4

Question 3

Which command is used on a Cisco Nexus switch to display the VXLAN network identifier (VNI) associated with a specific VLAN?

Accepted Answer

show vxlan vni. The 'show vxlan vni' command on Cisco Nexus switches displays the VXLAN network identifier (VNI) and its mapping to VLANs, including the associated VLAN ID and segment state. This command directly answers the question by showing the VNI-to-VLAN binding, which is essential for verifying VXLAN overlay configurations.

Answer

show vlan id 100

Answer

show interface nve 1

Answer

show running-config vxlan

Question 4

Answer

SSH to the server's OS

Answer

Vic CLI

Answer

UCS Manager GUI

Question 5

A data center network uses Cisco Nexus 9000 switches running NX-OS. The operations team notices that the CPU utilization on the supervisor module spikes intermittently, causing BGP session flaps. Analysis shows that the CPU spikes coincide with traceroute probes from external networks, which generate ICMP TTL exceeded messages that are process-switched. The engineer must implement a solution to protect the control plane without affecting normal ICMP functionality. The goal is to rate-limit ICMP traffic to a maximum of 1000 packets per second with a burst of 200 bytes, while allowing other control plane traffic without restriction. Which configuration should be applied?

Accepted Answer

class-map type control-plane match-all COPP-ICMP
  match protocol icmp
policy-map type control-plane COPP
  class COPP-ICMP
    police 1000 pps 200 byte burst
control-plane
  service-policy type control-plane COPP. It uses a Control Plane Policing (CoPP) policy with a class-map that matches ICMP protocol traffic in the control plane, then applies a police rate of 1000 pps with a 200-byte burst. This configuration rate-limits ICMP TTL-exceeded messages that are process-switched, protecting the supervisor CPU from spikes while allowing other control plane traffic unrestricted. The 'service-policy type control-plane' command applies the policy to the control plane, which is the proper method for NX-OS CoPP.

Answer

Use the 'hardware rate-limiter' feature to limit ICMP globally.

Answer

class-map type control-plane match-any COPP-ICMP
  match access-group name ICMP-ACL
policy-map type control-plane COPP
  class COPP-ICMP
    police rate 1000 pps burst 200
control-plane
  service-policy input COPP

Answer

Apply a QoS policy on the management interface to drop excess ICMP.

Question 8

A company is designing a HyperFlex cluster with 4 nodes and wants to tolerate the failure of any two nodes simultaneously while maintaining data availability. Which replication factor and cluster configuration should be used?

Accepted Answer

RF3 with 4 nodes. HyperFlex HXDP uses replication factor (RF) to determine data copies. RF3 replicates data three times, allowing the cluster to survive up to two concurrent node failures (if the cluster has at least 3 nodes). With 4 nodes, RF3 meets the requirement.

Answer

RF3 with 3 nodes

Answer

RF2 with 5 nodes

Answer

RF2 with 4 nodes

Question 9

During a UCS service profile configuration, an engineer needs to specify that the server should boot from a SAN LUN. Which boot policy type should be configured?

Accepted Answer

SAN boot policy. A SAN boot policy specifies the WWPN of the target and LUN ID to boot from a SAN LUN.

Answer

Local disk boot policy

Answer

PXE boot policy

Answer

Virtual media boot policy

Question 10

A financial services firm has deployed Cisco UCS C-Series rack servers running VMware vSphere 7.0. They use Cisco Intersight for management. Recently, a critical application server (Server-A) became unresponsive. The Intersight dashboard shows the server's health status as 'Warning' with a firmware compliance alert: the server's Cisco Integrated Management Controller (CIMC) firmware version is 4.0(1a), while the Intersight firmware baseline is 4.2(1c). The server is running ESXi 7.0u2 on a local datastore. The storage is provided by a Cisco MDS switch via Fibre Channel. The server has two 10GbE uplinks to the fabric interconnect. The engineer notices that the vCenter Server cannot communicate with Server-A, and all VMs on that host are isolated. The engineer suspects the issue is related to the firmware mismatch. What is the most appropriate first step to resolve this issue while minimizing downtime?

Accepted Answer

Upgrade the CIMC firmware on Server-A from 4.0(1a) to 4.2(1c) using Intersight's firmware update capability.. The CIMC firmware mismatch (4.0(1a) vs. baseline 4.2(1c)) is a known cause of management-plane instability in Cisco UCS C-Series servers managed by Intersight. Upgrading the CIMC firmware to match the Intersight baseline using Intersight's built-in firmware update capability directly addresses the root cause, restoring proper communication between the server, Intersight, and vCenter, while minimizing downtime by avoiding disruptive OS-level changes.

Answer

Check vCenter logs to determine why communication failed.

Answer

Reinstall ESXi on Server-A to ensure a clean operating system.

Answer

Change the Intersight firmware baseline to match the current CIMC version (4.0(1a)).

Question 11

An engineer receives an error 'XML namespace mismatch' when using NETCONF to configure a Nexus switch. The YANG model used is from the Cisco NX-OS openconfig model. What is the most likely cause?

Accepted Answer

The namespace in the XML payload does not match the YANG model. The 'XML namespace mismatch' error occurs when the namespace URI declared in the XML payload does not match the namespace defined in the YANG module. NETCONF uses the namespace to identify the correct YANG model for parsing the configuration data. If the namespace in the XML does not exactly match the one in the Cisco NX-OS openconfig YANG model, the switch rejects the operation with this specific error.

Answer

The switch is running in VM mode

Answer

The YANG model is not supported on this switch version

Answer

The NETCONF session is not authenticated

Question 12

Which type of I/O module (IOM) is installed in a UCS 5108 blade chassis to provide connectivity between blade servers and the fabric interconnects?

Accepted Answer

FEX (Fabric Extender). The IOMs in a 5108 chassis connect the blade midplane to the fabric interconnects via server ports. There are typically two IOMs for redundancy.

Answer

MDS switch

Answer

CIMC

Answer

Nexus 2000

Question 13

Accepted Answer

UCS Central. UCS Central provides global policy management across multiple UCS domains, including QoS policies.

Answer

UCS Manager

Answer

CIMC

Answer

HyperFlex Connect

Question 14

A network engineer notices that when a host sends a packet to a destination on a different VTEP, the packet is flooded to all VTEPs even though the destination MAC is known. What is the most likely cause?

Accepted Answer

The BGP EVPN route table is missing the MAC/IP route for the destination.. In a BGP EVPN VXLAN fabric, when a host sends a packet to a known destination MAC on a different VTEP, the ingress VTEP should perform MAC/IP route lookup in the BGP EVPN route table to determine the correct remote VTEP. If the MAC/IP route for the destination is missing (e.g., not advertised or withdrawn), the ingress VTEP has no mapping to a remote VTEP and must flood the packet to all VTEPs in the VNI, causing unnecessary broadcast traffic. This is the most likely cause of the described behavior.

Answer

The VNI is misconfigured.

Answer

The MTU exceeds 1500 bytes.

Answer

ARP suppression is disabled.

Question 15
