Actual Oracle 1Z0-821 Exam Questions

Question 1

Which two capabilities are provided by the OpenBoot PROM?

Aa command to safely shut down the system

Bhardware testing and initialization

Cbooting from a disk or network

Dstarting the GRUB loader

Correct answer: B, C

OpenBoot firmware is executed immediately after you turn on your system. The primary tasks of OpenBoot firmware are to:

* Test and initialize the system hardware (B)

* Determine the hardware configuration

*Boot the operating system from either a mass storage device or from a network (C)

*Provide interactive debugging facilities for testing hardware and software

Question 2

You run the command dlstat show-link -r.

Select the two correct statements regarding the information displayed in the INTRS column.

ANo value is listed for virtual network interfaces.

BA value of 0 is listed for virtual interfaces and ether stubs.

CThe number of Interrupts is listed, which indicates network efficiency.

DA number equal to the number of transmitted Ethernet frames is listed for physical links.

EThe number of packets that were interrupted by a collision is listed, which may indicate hardware problems.

Correct answer: C, E

In this output, the statistics for interrupt (INTRS) are significant. Low interrupt numbers indicate greater efficiency in performance. If the interrupt numbers are high, then you might need to add more resources to the specific link.

Example:

# dlstat -r -i 1

LINK IPKTS RBYTES INTRS POLLS CH<10 CH10-50 CH>50

e1000g0 101.91K 32.86M 87.56K 14.35K 3.70K 205 5

Note: dlstat show-link [-r [-F] | -t] [-i interval] [-a] [-p] [ -o field[, ...]] [-u R|K|M|G|T|P] [link]

Display statistics for a link.

-r

Display receive-side statistics only. Includes bytes and packets received, hardware and software drops, and so forth.

List of supported RX fields:

link

iusedby

ibytes

ipkts

intrs

polls

hdrops: hardware drops

sdrops: software drops (owing to bandwidth enforcement)

ch<10: number of packet chains of length < 10

ch10-50: number of packet chains of length between 10 and 50

ch>50: number of packet chains of length > 50

Question 3

You attempted to reboot a system via the init command, however the system did not perform boot sequence into the Oracle Solaris Operating Environment. You are presented with a prompt from the OpenBoot PROM. Which command would you enter, to boot the system from the default device?

Aboot -net install

Bboot

Cboot --default

Dboot --s0

Correct answer: B

Boot

With this form, boot loads and executes the program specified by the default boot arguments from the default boot device

Note: boot has the following general format:

boot [device-specifier] [arguments]

where device-specifier and arguments are optional.

Question 4

To help with your troubleshooting, you need to determine the version of the OBP. Which two commands will provide you with this information?

Aprintenv

Bbanner

C.version

Dset-env

Eshow-devs

Fvalue version

Correct answer: B, C

B: banner

Displays power-on banner.

The PROM displays the system banner. The following example shows a SPARCstation 2 banner. The banner for your SPARC system may be different.

SPARCstation 2, Type 4 Keyboard

ROM Rev. 2.0, 16MB memory installed, Serial # 289

Ethernet address 8:0:20:d:e2:7b, Host ID: 55000121

C: .version

Displays version and date of the boot PROM.

Note: OBP-OpenBootProm is a firmware which is placed on the sun machine's prom chip.

It is a os independent user interface to deal with the sun machine's hardware components.

The user interface provides one or more commands to display system information.

Question 5

A user brian is configured to use the bash shell. His home directory is /export/home/brian, and contains a .profile and a .bashrc file.

In the -profile, there are these lines:

genius =ritchie

export genius

In the .bashrc us this line:

genius=kernighan

In /etc/profile are these lines:

genius=thompson

export genius

When brian logs in and asks for the value of genius, what will he find, and why?

Agenius will be ritchie, because that was the value exported in .profile.

Bgenius will be kernighan, because .bashrc executes after .profile.

Cgenius will be ritchie because variable settings in .profile take precedence over variable settings in .bashrc.

Dgenius will be ritchie because .profile executes after .bashrc.

Egenius will be thompson because /etc/profile system settings always override local settings.

Correct answer: C
