Ok here's my next one:

b & c

I just added the first 10 questions to our test engine, you can take them here.

Q 9. You didn't configure your Ethernet interface to automatically start at boot time. How can you start it manually?

a. ping localhost
b. ethereal
c. ipconfig start eth0
d. ifconfig eth0 up

Answer tomorrow...

Exam Objective: 2.8 Select appropriate networking configuration and protocols (e.g., modems, Ethernet, Token-Ring)

answer is d.

With most Linux operating systems, where is the location for the compiled kernel?

a. /bin
b. /root
c. /homes
d. /dev
e. /usr

RussS

Whoops

Objective 4.5 Manage and navigate the Linux hierarchy

Drakonblayde

Hrm, maybe I've been playing with Red Hat too much, but I could have sworn the common directory for the kernel was /boot

copperpot

I say d. as well.

copperpot

I say the answer is e. for the compiled kernel

Answer D. is correct.

(Sorry about the delay, have been caught up by the new test engine, I'll try to pick it up again today.)

RussS

Anybody like to try again?

prolific

The compiled kernel goes in e. /usr ... then usually you copy the bzImage file from /usr/src/linux/arch/i386 to /boot/bzImage...

bin is for binary files like ls, rm, etc... so that makes no sense
root is root's home folder that makes no sense
no such thing as /homes
dev is for device files such as harddrive, cdrom, serial ports, etc

so the only reasonable answer would be e.

RussS

I guess this could be kind of tricky - the answer is /bin. Typically it is /bin or /usr /bin (and occasionally, but not often /usr /sbin), so the answer I was looking for was A. /bin because uven in the /usr directory it is in /bin.

Prolific gets 1/2 points for being on the right track

prolific

which distros put the compiled kernel under /bin ? im using gentoo and it is certainly not in /bin .. but under /usr

RussS

I was thinking most - my source was the Sybex Linux+ book. Of course, I could be wrong, but asking a friend who deals with many distros he assured me that this was the common location.

We always have to be aware that when it comes to Linux that some of the distros do things in slightly different ways. What we must always remember when sitting Linux+ is what Comptia wants Often I completely disagree with them, but if one wants that + certification then we have to put what we know aside and remember what is needed for a pass.

Let's continue this thread

10. Which of the following commands can be used to convert Debian software packages to RPM packages?

a. alien --to-rpm solitair.deb
b. deb -rpm solitair.deb
c. rpm -rebuild solitair.rpm solitair.deb
d. rebuild -deb solitair.rpm
e. convert -rpm solitair.deb

Answer: A. The alien command allows you to convert packages from Debien (.deb), Stampede (.slp), Slackware (.slp), or Red Hat package management (.rpm) to any of those other formats.

Exam objectives:

1.7 Identify strengths and weaknesses of different distributions and their packaging solutions (e.g, tar ball vs. RPM/DEB)

2.17 Install and uninstall applications after installing the operating system (e.g., RPM, tar, gzip)

str8rekt

A?

Webmaster

Indeed, the answer is A.

Here is another one:

11. You have been hired by a medium-sized company to implement hostname resolution, HTTP proxy services on a Linux server. Which of the following should you install? (Choose all that apply.)

a. BIND
b. SQUID
c. APACHE
d. DHCP
e. SAMBA

Correct Answers: a and b. SQUID is a popular proxy server for LINUX, and BIND is similar to DNS as it provides hostname to IP address resolution, and is popular in UNIX/Linux environments.

Exam objective: 1.6 Identify the function of different Linux services (e.g., Apache, Squid, SAMBA, Sendmail, ipchains, BIND)

Lexxdymondz

I would say A and C.

I know that BIND is the DNS server, but would the web server also act as a good http proxy???

Webmaster

Thanks for trying. The answers were Squid (proxy and firewall services), and BIND (DNS).

Here's the next, should be easy for those that passed Net+:

12. Which of the following protocols allow you to encrypt a remote adminstration session to your Linux box?

a. Telnet
b. SSH
c. RPM
d. SSL
e. SNMP
f. FTP

Answer: b. SSH stands for Secure Shell, which allows the user to open an encrypted remote login on remote servers.

Exam objective: 4.11 Use network commands to connect to and manage remote systems (e.g., telnet, ftp, ssh, netstat, transfer files, redirect Xwindow)

jzlvr1

Well, Seeing how no one has answered this question, I will take a stab at it.

I'm going to say B. SSH stands for Secure Shell, which allows the user to open an encrypted remote login on remote servers.

Thanks Daryl, for the answer and the explanation

Here's the next:

13. Which of the following file permissions attributes indicates read and write permissions for group public and owner, but no execute permissions?

a. 600
b. 640
c. 664
d. 666
e. 766
f. 777

jzlvr1

I've seen this question before. I downloaded some sample questions from some where, maybe from this site, maybe from Transcender. But this one tripped me up. There is no comma between the words group and public and I misread the question. The actual answer is: D.

Daryl Rose

Webmaster

I see I posted a question that I already put online in our test engine:

www.techexams.net/coexam/start.php?exam=linux

I'll post a new one soon... thanks for the comma

Webmaster

14. Where are user submitted CRON jobs stored?

a. The /var/spool/cron/username file.
b. The /etc/crontab file.
c. The /etc/cron.d directory.
d. The /etc/cron.hourly, /etc/cron.daily, /etc/cron.weekly, and /etc/cron.monthly directories.

Answer: a.

Explanation: The are four locations where CRON jobs can be stored.

- The /var/spool/cron/username file. This file is controlled by individual users, an example is /var/spool/cron/mary, where mary is the username.
- The /etc/crontab file. This is the system crontab file, and is controlled by root only.
- The /etc/cron.d directory. Files with the same format as the crontab file can be placed in this directory and is controlled by root only.
- The /etc/cron.hourly, /etc/cron.daily, /etc/cron.weekly, and /etc/cron.monthly directories. Scripts in these directories run at times specified in the /etc/crontab file and are controlled by root only.


5.2 Verify user and root cron jobs and understand the function of cron.

shubom

i would say b

Webmaster

The correct answer is A. Please read the explanation above.

I'm not going to continue this post (for those who didn't notice that yet ), instead I'll add some questions to our Linux+ practice exam. I'm planning on adding 10 today, maybe tomorrow.

Feel free to post your own questions as a reply on this post. If their good, we'll add them to our practice exam.

you should create a hard practice quiz all the ones ive found online havnt really helped
