220-1102 Malware Types and Removal Practice Question
This 220-1202 practice question tests your understanding of malware types and removal. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is investigating a computer that has been sending spam emails from the user's account without their knowledge. The user has not installed any new software recently. The technician finds a process running that matches a known botnet client. Which two steps should the technician take first to mitigate the threat?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "first"
Why it matters: Order matters here. You are being tested on which action comes before the others — not which action is generally useful.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Disconnect the computer from the network and terminate the malicious process.
The immediate priority is to disconnect the computer from the network to stop the botnet communication and prevent further spam. Then, the technician should identify and terminate the malicious process. Scanning without disconnecting may allow continued data exfiltration.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Disconnect the computer from the network and terminate the malicious process.
Why this is correct
Disconnecting stops the botnet's command-and-control communication, and terminating the process halts the spam.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Run a full antivirus scan and then update the firewall rules.
Why it's wrong here
Scanning without disconnecting may allow the botnet to continue sending data or receive commands.
✗
Change the user's email password and run a malware scan.
Why it's wrong here
Changing the password is important later, but the immediate threat is the active botnet process.
✗
Reboot the computer into Safe Mode and then run a scan.
Why it's wrong here
Safe Mode may help, but the first step should be network isolation to prevent further damage.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Trap categories for this question
Command / output trap
Scanning without disconnecting may allow the botnet to continue sending data or receive commands.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
