Braindumps for "117-101" Exam

General Linux, Part 1

 Question 1.
CORRECT TEXT
Which file holds information about the IRQ channels in use:

Answer: /proc/interrupts
Explanation: 
/proc/interrupts holds IRQ channels. /proc/ioports holds I/O memory addresses.
/proc/dma holds DMA channels.

Question 2.
CORRECT TEXT

Which file holds information about the I/O addresses in use:

Answer: /proc/ioports

Explanation: 
/proc/interrupts holds IRQ channels. /proc/ioports holds I/O memory addresses.
/proc/dma holds DMA channels.

Question 3.
CORRECT TEXT

What is the IO Address of the second serial port

Answer: 02f8
Answer: 02F8
Answer: 02F8h
Answer: 02f8h
Answer: 2f8
Answer: 2F8
Answer: 2f8h
Answer: 2F8h

Question 4.
COM2 normally uses what I/O port and IRQ combination?

A. 03F8 4
B. 02F8 3
C. 03E8 4
D. 02E8 3

Answer: B

Explanation: 
COM 1 uses an IRQ of 4 and a memory address of 03F8. COM 2 is assigned to IRQ 3 and a memory address of 02F8.

Question 5.
CORRECT TEXT
What is the IRQ of COM2?

Answer: 3

Explanation: 
COM 1 uses an IRQ of 4 and a memory address of 03F8. COM 2 is assigned to IRQ 3 and a memory address of 02F8.

Question 6.
You suspect that a new ethernet card might be conflicting with another device. 

Which file should you check within the /proc tree to learn which IRQs are being used by which kernel drives?

Answer: /proc/interrupts

Explanation:
The Linux /proc Directory is a Virtual Filesystem provided by linux kernel. /proc contains files and directories that let system administrators and programmers access system information. The file /proc/interrupts file contains information on interrupts and IRQs. First Ethernet card device name is eth0, second Ethernet card device name is eth1 ..., to identify that dev will conflict or not , see the contains of file. Already eth0 is appeared or not? 
Here is the output of /proc/interrupts CPU0
0: 380893 XT-PIC timer
1: 843 XT-PIC i8042
2: 0 XT-PIC cascade
5: 0 XT-PIC uhci_hcd
8: 1 XT-PIC rtc
11: 48 XT-PIC Intel 82801AA-ICH, eth0
14: 6086 XT-PIC ide0
NMI: 0
ERR: 0
For a multi-processor machine, this _le may look slightly different:
CPU0 CPU1
0: 1366814704 0 XT-PIC timer
1: 128 340 IO-APIC-edge keyboard
2: 0 0 XT-PIC cascade
8: 0 1 IO-APIC-edge rtc
12: 5323 5793 IO-APIC-edge PS/2 Mouse
13: 1 0 XT-PIC fpu
16: 11184294 15940594 IO-APIC-level Intel EtherExpress Pro
10/100 Ethernet
20: 8450043 11120093 IO-APIC-level megaraid
30: 10432 10722 IO-APIC-level aic7xxx
31: 23 22 IO-APIC-level aic7xxx
NMI: 0
ERR: 0
Appeared Number of CPU, Number of Ethernet card.

Question 7.
The command cat /proc/dma will show you what?

A. Whether DMA is enabled
B. Which DMA channels are in use
C. Which DMA mode is in use
D. General information about DMA on the machine

Answer: A

Explanation:
/proc/dma
This file contains a list of the registered ISA direct memory access (DMA) channels in use. A sample
/proc/dma files looks like the following:
4: cascade
It shows whether DMA is enabled or not.

Question 8.
In the BIOS, what setting should you disable so that your devices have the best chance of being recognized on boot-up?

A. AGP Fast Write
B. PnPOS
C. ACPI Support
D. Power Management/APM

Answer: C

Explanation:
ACPI (Advanced Configuration and Power Interface) is an open industry specification co-developed by Hewlett-Packard, Intel, Microsoft, Phoenix, and Toshiba. ACPI establishes industry-standard interfaces enabling OS-directed configuration, power management, and thermal management of mobile, desktop, and server platforms.

Question 9.
To set up a connection to your ISP via your modem, what should you do (choose all that apply):

A. configure the dialer
B. configure the PPP settings
C. configure the pppd daemon
D. configure the PPTP settings

Answer: A, B, C

Explanation: 
As described in Debian's support document, there are actually two parts to setting up a connection to your ISP. You have to configure the dialer (the chat program), and the PPP (Point-to-Point Protocol) settings (the pppd daemon). PPP is the protocol that modems use to communicate over a serial link. (PPP is a powerful protocol that is also often used when connecting distant routers over dedicated leased lines.)

Question 10.
The modem speed setting of _________ may be too high only if your computer doesn't have a 16550 UART chip.

A. 115200
B. 56700
C. 38400
D. 28800

Answer: A

Explanation: 
As described in Debian's support document, the speed setting of 115200 may be too high only if you have a 486 computer that doesn't have a 16550 UART chip. If you're using a 486 and not sure of the UART, play it safe and set the speed to 56700 instead. Exit the ee editor saving the file.
