QUESTION 81

If you were troubleshooting and wanted to look at SnapMirror log files, what is the path to these files?

 

A.

/vol/vol0/etc/log/snaplog/

B.

/vol/vol0/etc/snapmirror/

C.

/vol/vol0/etc/snaplog/

D.

/vol/vol0/etc/log/

 

Correct Answer: D

Explanation:

https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_snapmirror.1.html

The root volume is always vol0 and etc is contained therein. When exporting the root volume via NFS, thepath is/vol/vol0; so the full path to snapmirror log files is /vol/vol0/etc/log.

/etc/log/snapmirror.

 

This file logs SnapMirror activity. Log file for current week. /etc/log/snapmirror.[0-5]SnapMirror log files for previous weeks.

 

 

QUESTION 82

Which two statements apply to an entry in the /etc/exports file regarding exporting directories/qtrees and volumes? (Choose two.)

 

A.

Each volume must be exported separately.

B.

Exports are accessible only to hosts with names.

C.

User names used in an export must be resolvable.

D.

Exports can access multiple paths on the same volume.

 

Correct Answer: AD

Explanation:

https://library.netapp.com/ecmdocs/ECMP1196890/html/man5/na_exports.5.html

 

IP addresses and wildcards can be used when specifying host targets in exports.

User names are not valid exports options, save for the anon option which utilizes a local system UID or username (i.e. no user name mapping or resolution is performed.)

The highest level in the filesystem that can be specified for an export is the volume level. Implicitly this meansthat each volume must be exported separately.

An export provides access to paths below the export, implying that multiple paths on the same volume can beexported from an export.

 

 

QUESTION 83

Which three attributes would you specify when creating a LUN? (Choose three)

 

A.

The host operating system of the system attached to LUN.

B.

The version of Data ONTAP

C.

The size of the LUN.

D.

The path to the LUN.

 

Correct Answer: ACD

Explanation:

https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_lun.1.html

 

The usage for lun create is shown below. Options not in brackets are mandatory. lun create -s size -t ostype [ -o noreserve ] [ -e space_alloc ] lun_path This usage of the lun create command should be employed to create a new LUN of given size, with initiallyzero contents. The LUN is created at the lun_path given. No file should already exist at the given lun_path. Thedirectory specified in the lun_path must be a qtree root directory.

 

The size is specified in bytes. Optionally, a number followed by a one-character multiplier suffix can be used: c(1), w (2), b (512), k (1024), m (k*k), g (k*m), t (m*m). The size of the created LUN could be larger than the size specified, in order to get an integral number ofcylinders while reporting the geometry using SAN protocols.

 

The size of the LUN actually created is reported if it is different from that specified in the command.

The mandatory ostype argument is one of: solaris (the LUN will be used to store a Solaris raw disk in a singleslicepartition), windows (the LUN will be used to store a raw disk device in a single-partition Windows diskusing the MBR (Master Boot Record) partitioning style), hpux (the LUN will be used to store HP-UX data), aix(the LUN will be used to store AIX data), vld (the LUN contains a SnapManager VLD), linux (the LUN will beused to store a Linux raw disk without any partition table), netware (the LUN will be used to store NetWaredata), vmware (the LUN will be used to store VMware data), windows_gpt (the LUN will be used to storeWindows data using the GPT (GUID Partition Type) partitioning style), windows_2008 (the LUN will be used tostore Windows data for Windows 2008 systems), openvms (the LUN will be used to store Open-VMS data),xen (the LUN will be used to store Xen data), hyper_v (the LUN will be used to store Hyper-V data), solaris_efi(the LUN will be used to store Solaris_EFI data).

 

By default, the LUN is space-reserved. To manage space usage manually, -o noreserve can be specified.

Using this option will create a LUN without any space being reserved. Provisioning threshold events can beenabled by specifying -e space_alloc option. This option has to be used in conjunction with -o noreserve.

 

 

QUESTION 84

An aggregate is composed of twelve 36-Gigabyte disks. A drive fails and only 72-Gigabyte spare disks are available. Data ONTAP will then perform what action.

 

A.

Chooses a 72-Gigabyte disk and use it as is.

B.

Chooses a 72-Gigabyte disk and right-size it.

C.

Halts after 24 hour of running in degraded mode.

D.

Alerts you that there are no 36-Gigabyte disks and wait for one to be inserted.

 

Correct Answer: B

Explanation:

https://library.netapp.com/ecmdocs/ECMP1196986/html/GUID-8A91F6A2-61B8-42C3-AEAB7D5AA9BBE9CF.html

 

If a disk fails and no hot spare disk that exactly matches the failed disk is available, Data ONTAP uses the bestavailable spare. Understanding how Data ONTAP chooses an appropriate spare when there is no matchingspare enables you to optimize your spare allocation for your environment.

 

Data ONTAP picks a non-matching hot spare based on the following criteria (and more; in the link above):

If the available hot spares are not the correct size, Data ONTAP uses one that is the next size up, ifthere is one.

The replacement disk is downsized (aka right sized) to match the size of the disk it is replacing; theextra capacity is not available.

 

 

QUESTION 85

Which command is used to set the configuration of an Ethernet network interface?

 

A.

ifconfig

B.

C.

netstat – i

D.

sysconfig – v

 

Correct Answer: A

Explanation:

https://library.netapp.com/ecmdocs/ECMP1196979/html/man1/na_ifconfig.1.html

ifconfig – Configures network interface parameters.

 

 

QUESTION 86

Using the output below, a co-worker determined that these are types “Solaris” LUNs. What would your destination be?

 

lun show – m LUN patch mapped to LUN ID

 

——————————————————

 

/vol/vol1/lun0 solaris – igroup0 0 /vol/vol1/lun solaris- igroup1

 

0 /vol/vol1/qtree1/lun2 solaris – igroup2 0 /vol/vol1/qtree1/lun3 solaris – igroup3 0

 

A.

These are type “Solaris” LUNs.

B.

Not enough information is given here. Run the lun status command to get the information requested.

C.

Not enough information is given here. Run the lun show -v command to get the information requested.

D.

Correct Answer: C

 

 

QUESTION 87

The root admin on the UNIX box receives an “Access Denied” message when he attempts to access a newly mounted qtree. What’s the most likely cause of this error?

 

A.

The qtree is missing from the /etc/hosts file.

B.

NFS is turned off on the storage system.

C.

The qtree is set to ntfs security style.

D.

The qtree has not been exported.

 

Correct Answer: C

Explanation:

http://hd.kvsconsulting.us/netappdoc/801docs/html/ontap/smg/GUID-866DD79D-D2A6-4FBA-B0BDA63560FECEFF.html

https://library.netapp.com/ecmdocs/ECMP1196891/html/GUID-F6304830-B124-40A5-95D6-C646AA85E9E0.html

 

Only hostnames and IPs are referenced in /etc/hosts, so A is incorrect. Thequestionstates that the qtree wasmounted, and B and D would preclude this so they are incorrect.

You need to set a qtree to mixed or unix security style to support UNIX users.

 

 

QUESTION 88

Which statement is true about ASIS deduplication license with Data ONTAP 8.1?

 

A.

The existing 8.0 license key is used.

QUESTION 90

Which two will allow you to read and analyze a packet trace file generated by the storage system? (Choose two)

 

A.

WireShark

B.

Pktt

C.

Netmon

D.

Eternal View

 

Correct Answer: AC

Explanation:

pktt is part of the Data OnTap command set.

The output of pktt is not very human-readable, but it utilizes the tcpdump format which many traffic analyzerscan read or import. Only two such analyzers have been offered here.

Wireshark is the successor of Etherreal, and available for several platforms. Netmon is a Microsoft project,available for Windows, soon to be deprecated by the Microsoft Message Analyzer project.
