How Many Questions Of NS0-520 Testing Bible

NEW QUESTION 1

You install an ASA AFF A400 system with 32 GB FC SFP+ modules in port 0e and 0f. After creating the SVM and configuring the FCP protocol, the physical port stays offline. Referring to the exhibit which statement is correct?

• A. The current type of the ports must be configured as an initiator
• B. The current mode to the ports must be configured as an FC port
• C. The current mode for the ports must be set as an NVMe/FC port
• D. The admin status is manually set to down

Answer: B

Explanation:
Before using your UTA ports on a FC infraestructure, you need to modify the current mode from CNA to FC. You need to set the ports offline before you modify that parameter.

NEW QUESTION 2

What are two benefits of implementing VLANs for ISCSI configuration? (choose two)

• A. Reduced number of broadcast domains
• B. Increased performance
• C. Increased security
• D. Increased resiliency

Answer: AC

Explanation:
When you implement VLANs in large IP network infrastructures, you derive the following benefits: Increased security.
VLANs enable you to leverage existing infrastructure while still providing enhanced security because they limit access between different nodes of an Ethernet network or an IP SAN.

NEW QUESTION 4

While changing the network connections on your ONTAP cluster from twinax to fiber, the ports experience network connectivity issues. You want to verify which speeds the ports support and ensure that you
have supported transceivers. In this scenario which two actions would accomplish this task (choose two)

• A. Use hardware universe to determine the supported transceivers
• B. Use the interoperability matrix tool to determine the supported port speeds
• C. Use hardware universe to determine the supported port speeds
• D. Use the interoperability matrix tool to determine the supported transceivers

Answer: AC

Explanation:
Hardware universe will show information about port speeds and transceiver compatbility You can find more information on this link: https://hwu.netapp.com/Resources/hwu_ug.pdf (page 73)

NEW QUESTION 5

You have finished deploying a Netapp AFF All SAN Array Cluster and want to test the persistent ports feature. In this scenario, how would you accomplish this task?

• A. Perform a takeover of a node
• B. Disconnect an FCP initiator port
• C. Disconnect an FCP target port
• D. Disable a SAN LIF

Answer: A

Explanation:
If we don't have OnCommand Insight, then we should not pull out a cable as test because it won't be detected properly.
Doing a planned takeover will meet the requirements asked. Table Description automatically generated

Which NetApp tool provides a detailed inventory of SAN components?

• A. Active IQ OneCollect
• B. Interoperabilty Matrix Tool
• C. Active IQ config advisor
• D. Hardware Universe

Answer: A

Explanation:
ActiveIQ OneCollect is a tool from NetApp that will create an inventory of your environment that will include hosts, switches and storage and validate it against the IMT (Interoperability Matrix Tool).

NEW QUESTION 7

An administrator wants to implement FCoE for connectivity of an AFF A200 using VLAN 3011 for fabric traffic across VSAN 11. When configuring the Nexus switches for FCoE connectivity, which two actions are required? (Choose two.)

• A. Create a new virtual FC interface and bind the physical interface to it.
• B. Add the virtual interface to the VSAN.
• C. Create a port channel and add all of the physical network ports that will have FCoE LIFs.
• D. Add the adapter MAC address to the network port configuration where the node is connected.

Answer: BC

NEW QUESTION 8

You want to connect a NetApp AFF A700 to a 32 Gb FC switch. The ports need to connect at 32 Gb speed. In this scenario, which statement is correct?

• A. The AFF A700 includes FC ports natively on the controller.
• B. The AFF A700 includes an additional FC I/O module that is already populated in each controller.
• C. You need to purchase a two-port or four-port unified I/O module that enables FC and Ethernet connectivity.
• D. You need to purchase a two-port or four-port FC I/O module.

Answer: C
