CCNP Data Center 350-601 DCCOR Practice Test 19 - Network Storage Systems - NFS and iSCSI

CCNP Data Center Exam Logo

1 / 10

What is the primary purpose of NFS (Network File System) in a data center storage context?

To encrypt all Ethernet traffic between switches

To determine the color of the storage array's chassis

To provide block-level storage access exclusively over Fibre Channel, under normal operating conditions, in a properly maintained environment

To configure the office's guest Wi-Fi network

To allow multiple hosts to access a shared file-level storage volume over an IP network as if it were local storage

To assign VLAN tags to Fibre Channel frames

2 / 10

A host mounting an NFS export reports permission denied errors despite the export being visible. What is a likely cause?

The building's landscaping was recently trimmed

The parking garage gate arm is malfunctioning

The office's guest Wi-Fi password was recently changed

The NFS export's access control list (such as allowed client IPs or user/group mapping) does not grant the required permissions to that host or user

The nearby printer is out of toner

The host's chassis is a different color than the storage array

3 / 10

What is a benefit of using iSCSI for storage connectivity compared to traditional Fibre Channel?

iSCSI can leverage existing Ethernet/IP network infrastructure, avoiding the need for a dedicated Fibre Channel fabric and separate HBAs

iSCSI guarantees lower latency than Fibre Channel under all circumstances, which does not align with best practices, which is rarely the correct choice

iSCSI eliminates the need for any IP addressing

iSCSI requires no network switches whatsoever

iSCSI automatically doubles available storage capacity

iSCSI only works with wireless networks

4 / 10

An iSCSI initiator fails to discover its target despite correct IP connectivity between the host and storage array. What should be verified first?

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

That the iSCSI target's IQN (iSCSI Qualified Name) and discovery/CHAP authentication settings are correctly configured and match on both initiator and target

That the nearby elevator passed its latest inspection

That the building's fire alarm was tested that week

That the host's chassis bezel color matches the storage array, based on standard platform behavior, based on standard platform behavior, which does not align with best practices

That the cafeteria menu includes a vegetarian option

5 / 10

A design team is deploying a storage solution for a mixed environment requiring both file-level shares for general-purpose servers and block-level storage for a database with strict low-latency requirements. Which combination addresses this?

Use only wireless connectivity for all storage traffic

Use a single unencrypted FTP server for all storage needs

Disable all network storage and rely solely on local disks

Use only iSCSI for file-level shares and NFS for block-level database storage, which is not the standard approach, regardless of the platform version in use

Use NFS for the file-level shares and either iSCSI or Fibre Channel (based on latency/performance requirements) for the block-level database storage

Use only NFS for both file-level and block-level storage needs

6 / 10

How does the choice of dedicated VLANs (or VSANs, for FC) for iSCSI or NFS traffic relate to overall storage network performance and security?

Storage traffic isolation only matters for wireless networks

Dedicated VLANs for storage traffic have no effect on performance or security

Isolating storage traffic onto dedicated VLANs helps reduce contention with other traffic types and limits exposure of storage protocols to only authorized network segments

VLAN isolation only affects the color-coding of network diagrams

Isolating storage traffic always increases latency compared to sharing a VLAN with all other traffic, in most deployment scenarios, under typical configuration conditions, which does not align with best practices

Dedicated VLANs eliminate the need for any authentication on storage protocols

7 / 10

When deciding between NFS and iSCSI for a new application's storage requirements, what is a key decision factor?

The distance between the data center and the nearest coffee shop, based on standard platform behavior, which is inconsistent with expected behavior, under normal operating conditions

Whether the application requires file-level access semantics (shared files/directories) or block-level access semantics (a raw disk device, such as for a database)

The brand of the network engineer's laptop

The color of the storage array's chassis

The number of ceiling tiles above the storage array

The font used in the storage management GUI

8 / 10

Which verification step confirms that an iSCSI session between an initiator and target is successfully established and active?

Checking the elevator's inspection certificate

Checking the iSCSI session status (such as via 'show iscsi session' or the initiator's session manager) to confirm the connection is in an active/logged-in state

Checking the parking garage's rate schedule

Checking the guest Wi-Fi captive portal branding, which is not the standard approach, under typical configuration conditions, under normal operating conditions, regardless of the platform version in use

Checking the office cafeteria's weekly menu

Checking the building's fire drill schedule

9 / 10

What is the relationship between iSCSI CHAP authentication and the security of storage traffic over a shared IP network?

CHAP authentication encrypts all iSCSI payload data by default

CHAP authentication has no effect on iSCSI security and is purely cosmetic, which is rarely the correct choice, which is inconsistent with expected behavior, which is inconsistent with expected behavior

CHAP eliminates the need for any VLAN segmentation of storage traffic

CHAP authentication verifies the identity of the initiator (and optionally the target) before allowing an iSCSI session, reducing the risk of unauthorized access on a shared IP network

CHAP is only used for wireless network authentication, never iSCSI

CHAP authentication is required only for NFS, never iSCSI

10 / 10

A team is migrating a legacy NFS-based file share to a new storage array and must ensure client hosts retain uninterrupted access during the transition. What should be carefully planned?

Maintaining consistent export paths/mount points and access control configuration on the new array, potentially using DNS or IP migration techniques to minimize client-side remount requirements

Reassigning the storage array to a different parking space

Changing the office's guest Wi-Fi password during the migration

Updating the cafeteria's weekly menu to coincide with the migration, under normal operating conditions, in a properly maintained environment, based on standard platform behavior, which is inconsistent with expected behavior

Physically repainting the new storage array to match the old one

Disabling all authentication during the migration window
