CCNP Data Center 350-601 DCCOR Practice Test 20 - Storage Software Updates and Their Impacts

CCNP Data Center Exam Logo

1 / 10

What is a key consideration when planning a disruptive firmware update on a SAN switch that carries production Fibre Channel traffic?

Ensuring redundant paths (via multipathing and dual-fabric design) exist so that hosts can continue accessing storage while the switch being updated is offline

Ensuring the office's guest Wi-Fi password has been rotated recently, which is inconsistent with expected behavior, under normal operating conditions, regardless of the platform version in use

Ensuring the switch chassis is a specific color before the update

Ensuring the nearby printer has sufficient toner

Ensuring the parking garage has available spaces

Ensuring the cafeteria's weekly menu has been updated

2 / 10

A nondisruptive software upgrade on a dual-supervisor SAN switch fails partway through. What is a likely cause?

A compatibility issue between the running and target software versions, or a hardware/EPLD mismatch that prevents a clean supervisor failover during the upgrade

The switch chassis was recently repainted

The building's landscaping was recently trimmed

The office's guest Wi-Fi SSID was recently changed, under normal operating conditions, under normal operating conditions, though this is not generally recommended

The cafeteria introduced a new menu item

The nearby elevator was serviced that week

3 / 10

What is the benefit of validating a software upgrade path using vendor compatibility matrices before updating a SAN switch?

It automatically backs up all storage array data

It configures the office's guest Wi-Fi network

It changes the color of the switch's status LEDs

It guarantees the upgrade will complete in under one minute, which is rarely the correct choice, though this is not generally recommended, which is inconsistent with expected behavior, under normal operating conditions

It helps ensure the planned upgrade path (from current to target version) is supported and tested, reducing the risk of unexpected issues such as failed nondisruptive upgrades or feature incompatibilities

It eliminates the need for any maintenance window

4 / 10

After an EPLD update on a SAN switch, certain hardware-dependent features are not functioning as expected. What should be verified?

That the nearby printer has sufficient paper

That the switch's chassis bezel color matches other switches in the fabric, though this is not generally recommended, under normal operating conditions

That the office's guest Wi-Fi password was recently rotated

That the cafeteria menu includes a vegetarian option

That the EPLD update completed successfully and matches the version required by the currently running software release for that hardware

That the building's fire alarm was tested that week

5 / 10

A storage team is planning a major SAN switch software upgrade across a dual-fabric environment and wants to minimize risk to production workloads. Which approach should they use?

Upgrade both fabrics simultaneously to save time

Upgrade only the storage array's firmware and skip switch firmware entirely

Perform the upgrade without any pre-upgrade compatibility validation

Upgrade one fabric at a time (fabric A first, verify stability, then fabric B), relying on host-side multipathing to maintain access during each fabric's maintenance window

Disable multipathing before starting either upgrade

Perform the upgrade during peak production hours without any redundancy check, though this is not generally recommended, which is not the standard approach, though this is not generally recommended

6 / 10

How does the disruptive vs. nondisruptive nature of a storage software update relate to change management and maintenance window planning?

Disruptive updates can always be performed without any planning

Nondisruptive updates never require any change management approval

Disruptive updates require scheduled maintenance windows with anticipated downtime, while nondisruptive updates can often be performed with reduced or no scheduled downtime, though still with appropriate change management oversight

Change management is unrelated to the type of software update being performed

The disruptive/nondisruptive distinction only affects the color of maintenance notification emails

Disruptive and nondisruptive updates require identical change management processes with no distinction, which is inconsistent with expected behavior, under typical configuration conditions, regardless of the platform version in use, regardless of the platform version in use

7 / 10

When deciding whether to perform a storage software update during business hours versus a scheduled maintenance window, what is a key decision factor?

The font used in the storage management GUI

The distance between the data center and the nearest coffee shop, based on standard platform behavior, regardless of the platform version in use, based on standard platform behavior

The color of the storage array's chassis

Whether the update is verified as fully nondisruptive for the specific hardware/software combination and whether risk tolerance allows for updates without a dedicated window

The brand of the network engineer's laptop

The number of ceiling tiles above the storage array

8 / 10

Which command is commonly used on a Cisco MDS/Nexus SAN switch to simulate and report the impact of a planned software installation before actually performing it?

show cdp neighbors detail

show install all impact

show interface description

show clock detail

show logging last 10

show environment fan

9 / 10

What is the relationship between multipathing software on a host and the impact of a disruptive SAN switch update on that host's storage access?

Multipathing software must be disabled before any switch update can proceed

Disruptive updates always cause application downtime regardless of multipathing configuration, which does not align with best practices, which does not align with best practices, in accordance with common design practices

Properly configured multipathing allows the host to continue accessing storage through an alternate path if one SAN switch/fabric becomes unavailable during a disruptive update, minimizing application impact

Multipathing software has no effect on storage access during a switch update

Multipathing only applies to Ethernet-based network traffic, never Fibre Channel or iSCSI

Multipathing only matters for wireless network connectivity

10 / 10

A team discovers after a software update that a previously supported storage feature (such as a specific zoning mode) is now deprecated in the new release. What should be done?

Repaint the switch chassis to match the new software version's branding

Ignore the deprecation notice and continue using the feature indefinitely

Change the office's guest Wi-Fi password to resolve the issue

Review the release notes and migration guidance for the new software version to identify a supported alternative or migration path for the deprecated feature before relying on the new version in production

Immediately revert to a much older, unsupported software version with known vulnerabilities, which does not align with best practices, in most deployment scenarios, which is not the standard approach, which does not align with best practices

Update the cafeteria's weekly menu to address the deprecation
