Best Dumps among other dumps providers. I like it so much because of their authenticity.

Kaiden Oct 22, 2026

That's great. I've used other dump providers in the past and they were often outdated or had incorrect information. This time I will try it.

Cecilia

Yes, I passed my certification exam using Cramkey Dumps.

Helena Oct 6, 2026

Great. Yes they are really effective

Nell

Are these dumps reliable?

Ernie Oct 21, 2026

Yes, very much so. Cramkey Dumps are created by experienced and certified professionals who have gone through the exams themselves. They understand the importance of providing accurate and relevant information to help you succeed.

Josie

I just passed my certification exam using their dumps and I must say, I was thoroughly impressed.

You’re right. The dumps were authentic and covered all the important topics. I felt confident going into the exam and it paid off.

Anaya

I found so many of the same questions on the real exam that I had already seen in the Cramkey Dumps. Thank you so much for making exam so easy for me. I passed it successfully!!!

Nina Oct 18, 2026

It's true! I felt so much more confident going into the exam because I had already seen and understood the questions.

Question 17

A Linux administrator provisioned a new web server with custom administrative permissions for certain users. The administrator receives a report that user1 is unable to restart the Apache web service on this server. The administrator reviews the following output:

[ root@server ] # id user1

UID=1011 (user1) gid=1011 (USER1) groups=1011 (user1), 101 (www-data), 1120 (webadmin)

[ root@server ] # cat /etc/sudoers.d/custom.conf

user1 ALL=/usr/sbin/systemctl start httpd, /usr/sbin/systemctl stop httpd

webadmin ALL=NOPASSWD: /etc/init.d.httpd restart, /sbin/service httpd restart, /usr/sbin/apache2ctl restart

#%wheel ALL=(ALL) NOPASSWD: ALL

Which of the following would most likely resolve the issue while maintaining a least privilege security model?

Options:

User1 should be added to the wheel group to manage the service.

User1 should have "NOPASSWD:" after the "ALL=" in the custom. conf.

The wheel line in the custom. conf file should be uncommented.

Webadmin should be listed as a group in the custom. conf file.
