Question: 1 
   
A technician installed a known-good, compatible motherboard on a new laptop. However, the 
motherboard is not working on the laptop. Which of the following should the technician MOST likely 
have done to prevent damage? 
 
A. Removed all jewelry 
B. Completed an inventory of tools before use 
C. Practiced electrical fire safety 
D. Connected a proper ESD strap 
 
Answer: D     
 
Explanation: 
The technician should have connected a proper ESD strap to prevent damage to the motherboard. ESD 
(electrostatic discharge) can cause damage to electronic components, and an ESD strap helps to prevent 
this by grounding the technician and preventing the buildup of static electricity. Removing all jewelry is 
also a good practice, but it is not the most likely solution to this problem. 
 
Question: 2 
   
A technician receives a ticket indicating the user cannot resolve external web pages However, specific IP 
addresses are working. Which of the following does the technician MOST likely need to change on the 
workstation to resolve the issue? 
 
A. Default gateway 
B. Host address 
C. Name server 
D. Subnet mask 
 
Answer: A     
 
Explanation: 
The technician most likely needs to change the default gateway on the workstation to resolve the issue. 
The default gateway is the IP address of the router that connects the workstation to the internet, and it 
is responsible for routing traffic between the workstation and the internet. If the default gateway is 
incorrect, the workstation will not be able to access external web pages.

A technician needs to recommend the best backup method that will mitigate ransomware attacks. Only 
a few files are regularly modified, however, storage space is a concern. Which of the following backup 
methods would BEST address these concerns? 
 
A. Full 
B. Differential 
C. Off-site 
D. Grandfather-father-son 
 
Answer: B     
 
Explanation: 
The differential backup method would best address these concerns. Differential backups only back up 
files that have changed since the last full backup, which means that only a few files would be backed up 
each time. This would help to mitigate the risk of ransomware attacks, as only a few files would be 
affected if an attack occurred. Additionally, differential backups require less storage space than full 
backups. 
 
Question: 4 
   
A change advisory board did not approve a requested change due to the lack of alternative actions if 
implementation failed. Which of the following should be updated before requesting approval again? 
 
A. Scope of change 
B. Risk level 
C. Rollback plan 
D. End user acceptance 
 
Answer: C     
 
Explanation: 
The rollback plan should be updated before requesting approval again. A rollback plan is a plan for 
undoing a change if it causes problems, and it is an important part of any change management process. 
If the change advisory board did not approve the requested change due to the lack of alternative actions 
if implementation failed, then updating the rollback plan would be the best way to address this concern.

A. Reset the phone to factory settings 
B. Uninstall the fraudulent application 
C. Increase the data plan limits 
D. Disable the mobile hotspot. 
 
Answer: B     
 
Explanation: 
Installing applications directly from a vendor's website can be risky, as the application may be malicious 
or fraudulent. Uninstalling the application can help mitigate the issue by removing the source of the 
problem.
