QUESTION 31

During an equipment move a Fibre Channel cable from a host to a switch is accidentally plugged into a different switch port on the FC switch. However, the host still sees the storage devices on all its paths. What are two reasons why this is possible? (Choose two.)

 

A.

LUN masking uses switch port numbers and not WWPNs.

B.

The host HBA WWPN is a part of a WWPN zoning scheme.

C.

The Fibre Channel address for the HBA has not changed.

D.

The WWPN Alias was n changed on the NetApp Controllers.

 

Correct Answer: BD

 

 

QUESTION 32

You connect a host to a NetApp storage system through an FC switch. The host has its boot volumes on the NetApp storage system. What is mandatory for you to configure?

 

A.

persistent binding

B.

port zoning

C.

portsets

D.

WWPN zoning

 

Correct Answer: A

 

 

QUESTION 33

A Solaris administrator just noticed that a host has lost connectivity to the company SAN. Which file should the administrator check for SAN connectivity errors?

 

A.

/opt/errorlog.log

B.

/etc/syslog

C.

/var/adm/messages

D.

/etc/sysevent

 

Correct Answer: C

 

 

QUESTION 34

Which NetApp host utility command determines the number of paths per LUN visible to the host?

 

A.

sanlun path show

B.

sanlun lun show -p

C.

sanlun fcp show adapter -p

D.

sanlun fcp show adatper -c

 

Correct Answer: B

 

 

QUESTION 35

You have a Windows 2003 host using the NetApp ONTAP DSM MPIO environment with a FAS6000 high availability configuration running single image cfmode. When you disconnect a cable from the FC switch to a storage target port, how will the I/O fail over?

 

A.

I/O will fail over to any port on the original controller but NOT on the partner controller that is part of the associated portset. Choice of path will be controlled by the host’s MPIO weighting table.

B.

I/O will fail over to any port on either controller that is part of the associated portset. Choice of path will be controlled by the host’s MPIO weighting table.

C.

I/O will fail over to any port on the original controller that is part of the associated portset. Choice of path will be controlled by NetApp storage system igroup settings.

D.

I/O will fail over to any port on either controller that is part of the associated portset. Choice of path will be controlled by NetApp storage system igroup settings.

 

Correct Answer: B

 

 

QUESTION 36

Which host-based tool will enable you to stripe a LUN across multiple NetApp controllers?

 

< tr style="mso-yfti-irow: 1">

A.

multipathing software

B.

host-based file system

C.

host-based volume manager

D.

HBA driver

 

Correct Answer: C

 

 

QUESTION 37

What are two possible impacts to consider when changing the cfmode to single_image?. (Choose two.)

 

A.

There more paths to LUNs.

B.

Target port WWPNs will change on at least one controller.

C.

You must use hard zoning (zoning by ports).

D.

There are fewer paths to LUNs.

E.

hosts running Solaris since it does not support single_image cfmode

 

Correct Answer: AB

 

 

 

 

 

 

 

QUESTION 38

Click the Exhibit button. A Solaris 10 host with VERITAS Storage Foundation 4.1 is FCP attached to a FAS3140 high availability storage system running single image cfmode. Using the diagram shown, which ports will be considered active by VERITAS DMP using the NetApp ASL to a LUN on controller 1 mapped to host 1?

 

clip_image002

 

A.

Port 0b on controller 1 only

B.

Port 0d on controller 1 only

C.

Port 0b and 0d on controller 1 only

D.

Ports 0b and 0d on both controller 1 and controller 2

 

Correct Answer: C

 

 

QUESTION 39

What are two functions of iSCSI access lists? (Choose two.)

 

A.

control the network interfaces on the storage system that an initiator can access

B.

define authentication parameters(CHAP)

C.

limit the number of network interfaces advertised by the storage system

D.

define MPIO behavior

 

Correct Answer: AC

 

 

 

QUESTION 40

What is the significance of using a specific LUN type when creating LUNs manually on a NetApp storage system?

 

A.

The LUNs offset, size of the prefix and suffix is determined by the LUN type, which differs for different operating systems.

B.

The LUN types are merely for administrative ease of use and the LUN types can be changed on the fly after creation.

C.

The LUN types allow the appropriate host operating systems to use the LUN. For example, a VMware type LUN cannot be read from /written to using a Solaris host.

D.

The host operating system will panic when the “wrong” LUN type is selected on the NetApp storage system.

 

Correct Answer: A
