2) A number of users are unable to access some resources on the file server. Upon your review, you got these
Network information and settings:
Name: World Wide Technology
IP: 192.100.200.30
Mask :255.255.255.0
Gateway: 192.100.200.1
DNS : 8.8.8.8
and
4.2.2.1
Open Ports :
25, 80, 110, 443, 3306
Which of the following is the most likely explanation?
a) the route was removed from the routing table
b) the server lost power and was not able to power on.
c) the gateway is wrong
d) some ports were closed during routine hardening.
Instructor’s Notes:
Choices a, b and c will produce no network connection at all. Whereas choice “d” means no connection
Other than those apps using the givem open ports. The users can browse the internet (ports 80 and 443), can send
and receive email messages (ports 25 and 110) and can use SQL (port 3306). However, it cannot to ftp (port 21),
SSH (port 22), remote desktop (port 3389), etc.
3) The blade server is experiencing performance degradation

Your application server is experiencing poor performance. Click on Server 1 and server 2 and evaluate the
given information to determine which drives need to be replaced.
Then identify the appropriate replacement drive that should be used for the least performance degradation
to the server.

Instructor’s Notes:
1. You need to click server 1 and 2. one a a time to see their corresponding information
2. Watch out for the words – Failed, offline, Failure predicted.
3. Whichever drives have these keywords, you need to click them one at a time
4. Look for drop down that shows the replacement drives.
5. Be sure the values you will select match its original specifications. For example, since it is RAID5,
the replacement HDD should be of the same type and size of the original. i.e. SAS, 2 TB
• Disk 2
• Disk 3
• Disk 4
• Disk 5

Therefore:
1) Replace disk 5
2) With 2TB SAS hard drive

4) Investigate the network settings. Define the source of network connectivity problem.
Then indicate/select/implement our resolution
For example:
server 2

FAILED (or Predicted to Fail, bad, not working)
Then you resolution will be:
1) change disk 5 in server 2
2) drive type is SAS
3) HD size is 2TB
You are reviewing the settings of a workstation which cannot access the internet.
IP: 192.168.100.10
SM: 255.255.255.0
Gateway: 192.168.1.1
Which of the following is causing the problem?
a) It is using DCHP
b) The subnet mask is configured incorrectly
c) It has incorrect gateway
d) IPv6 should be used
Instructor’s Notes:
If “incorrect gateway is not in the choices, but you see incorrect IP address.
then select incorrect IP address as your answer.
