QUESTION 1
List the syntax supported by the Cluster Verification Utility (CVU). (select all that apply)
A. comp – To show valid components with description
B. stage – To list pre and post checks of stages
C. asm – To list valid disks available
D. dbstat – To list number of instances available online
Answer: AB
Explanation:
A: To verify the minimal system requirements on the nodes prior to installing Oracle Clusterware
or Oracle RAC, use the sys component verification command as follows:
cluvfy comp sys [ -n node_list ] -p { crs | database } } [-r { 10gR1 |
10gR2 | 11gR1} ] [ -osdba osdba_group ] [ -orainv orainventory_group ]
[-verbose]
B: To verify whether your system meets all of the criteria for an Oracle Clusterware installation,
use the -pre crsinst command for the Oracle Clusterware installation stage as follows:
cluvfy stage -pre crsinst -n node_list
[ -c ocr_location ] [-r { 10gR1 | 10gR2 | 11gR1} ][ -q voting_disk ]
[ -osdba osdba_group ]
[ -orainv orainventory_group ] [-verbose]

QUESTION 4
Which tool can be used to specify network interfaces and to retrieve component configuration
information?
A. CVU
B. SRVCTL
C. CRSCTL
D. OIFCFG
Answer: D
Explanation:
The Oracle Interface Configuration (OIFCFG) command-line interface helps you to define and
administer network interfaces. You can issue OIFCFG commands in single-instance and Oracle
Clusterware environments to:
Allocate and deallocate network interfaces to components Direct components to use specific
network interfaces Retrieve component configuration information

QUESTION 5
You want to set full debugging for the communications and resource management components
for the CRS module on nodes host01 and host03. How can you accomplish this?
A. crsctl set log CRS “CRSCTL: 5, CRSCOMM: 5” -nodelist host01, host03
B. crsctl lsmodules crs set log CRSCTL: 5, CRSCOMM: 5 -nodelist host01, host03
C. srvctl set log -m CRSCTL5, CRSCOMM 5 -n host01, host03
D. ocrconfig set log CRS “CRSCTL, CRSCOMM: 5” -nodelist host 01, host03
Answer: A
Explanation:
To set log levels for the CRSRTI and CRSCOMM components of the CRS module:
$ crsctl set log crs “CRSRTI=1,CRSCOMM=2”

QUESTION 6
What would be the total space required for Clusterware files when stopping them in the ASM
Diskgroup configured with NORMAL redundancy? (Assume each OCR and voting Disk files uses
300 MB.)
A. 1.5 GB
B. 2.4 GB
C. 600 MB
D. 900 MB
Answer: A
Explanation:
