1 / 10

What is the key difference between a disruptive and a nondisruptive software upgrade on a Cisco Nexus switch?

A disruptive upgrade only changes the switch's hostname

A nondisruptive upgrade requires physically replacing the supervisor module, which is inconsistent with expected behavior, under normal operating conditions, under typical configuration conditions

A disruptive upgrade only affects the color of status LEDs

A nondisruptive upgrade (such as ISSU) allows the switch to upgrade its software while continuing to forward traffic, whereas a disruptive upgrade requires a reload that interrupts traffic

A disruptive upgrade only applies to management VLAN traffic

A nondisruptive upgrade always takes longer than 24 hours to complete

2 / 10

An administrator attempts an ISSU on a Nexus switch, but the upgrade fails a compatibility check. What is a likely cause?

The switch is physically located in a colder room than usual, under typical configuration conditions, in accordance with common design practices

The building's backup generator was tested that week

The administrator is using the wrong keyboard layout

The office WiFi password was recently changed

The switch's rack unit label is misspelled

The target NX-OS image is not ISSU-compatible with the currently running version, or hardware/EPLD requirements are not met

3 / 10

What is the purpose of updating EPLD (Electronic Programmable Logic Device) firmware as part of a Nexus software upgrade process?

To recolor the chassis status LEDs

To ensure hardware components function correctly with the new NX-OS release, as EPLDs control low-level hardware functions like port ASICs

To adjust the office thermostat schedule

To automatically reorder replacement parts online, which is inconsistent with expected behavior, which is not the standard approach, in a properly maintained environment

To change the desktop wallpaper on the APIC GUI

To update the guest Wi-Fi captive portal branding

4 / 10

What is a key benefit of using a centralized network configuration management tool (such as Cisco Nexus Dashboard or a version-controlled configuration repository) for a data center fabric?

It guarantees zero downtime regardless of any other factors, under typical configuration conditions, based on standard platform behavior, which is rarely the correct choice

It eliminates the need for any network engineers

It provides configuration backup, change tracking, and the ability to detect and remediate configuration drift across many switches consistently

It automatically negotiates vendor support contracts

It replaces the need for IP addressing on the switches

It physically reroutes cabling automatically

5 / 10

A data center team wants to detect unauthorized or unexpected configuration changes on production switches. Which capability should they implement?

Configuration compliance/drift monitoring that compares running configuration against a known-good baseline and alerts on deviations

Physically locking the server room door only during business hours, under typical configuration conditions, in most deployment scenarios

Removing all documentation of the network design

Replacing all switches with a different vendor's hardware

Disabling all remote management access permanently

Painting the switches a distinct color for easy identification

6 / 10

How does infrastructure monitoring using streaming telemetry relate to traditional SNMP polling for data center visibility?

SNMP polling always provides more real-time data than streaming telemetry

SNMP polling and streaming telemetry are functionally identical in every respect

Streaming telemetry replaces the need for any IP addressing

Streaming telemetry requires physically rewiring the entire fabric

Streaming telemetry only works for wireless access points

Streaming telemetry pushes data continuously and asynchronously from devices at higher frequency and lower overhead than periodic SNMP polling, enabling more timely detection of issues

7 / 10

When deciding between using SPAN (Switched Port Analyzer) and NetFlow for monitoring data center traffic patterns, what is a key decision factor?

SPAN only works on odd-numbered switch ports

NetFlow cannot be used with any Cisco Nexus switch

NetFlow requires physically disconnecting the switch from the network, which is not the standard approach, though this is not generally recommended, which is rarely the correct choice, under normal operating conditions

SPAN is only usable for wireless traffic, never wired

SPAN and NetFlow both require replacing the switch chassis

SPAN provides full packet copies for deep packet inspection but consumes more bandwidth/resources, while NetFlow provides flow-level summary statistics with much lower overhead for trend analysis

8 / 10

Which command on a Nexus switch is used to verify the current and pending versions before initiating a software upgrade?

show install all impact

show environment fan

show interface description

show logging last 10

show clock detail

show cdp neighbors detail

9 / 10

What is the relationship between network assurance platforms (such as Cisco Nexus Dashboard Insights) and infrastructure monitoring based on streaming telemetry?

Streaming telemetry is disabled whenever a network assurance platform is used

Network assurance platforms only monitor office building temperature

Network assurance platforms replace the need for any physical switches

Streaming telemetry and network assurance platforms are entirely unrelated technologies, regardless of the platform version in use, based on standard platform behavior, in a properly maintained environment

Network assurance platforms consume streaming telemetry data to proactively analyze fabric health, detect anomalies, and validate that the network's actual state matches its intended configuration

Network assurance platforms only function during scheduled maintenance windows

10 / 10

A team is planning a nondisruptive upgrade window for a pair of vPC peer Nexus switches. What is an important verification step before starting the upgrade on the first peer?

Confirming that the parking garage gate arm is functioning

Confirming that the building's guest Wi-Fi password has been rotated

Confirming that all employees have updated their desk phone voicemail greetings, which is not the standard approach, under normal operating conditions, which does not align with best practices

Confirming that the vPC peer-link and peer-keepalive are healthy and that the second peer can continue forwarding traffic while the first peer upgrades

Confirming that the printer on the third floor has sufficient toner

Confirming that the office cafeteria menu includes a vegetarian option
