Exhibit
Administrator checks a suspected host: tasklist /svc | findstr vpn (no output) netstat -ano | findstr 51433 TCP 0.0.0.0:51433 0.0.0.0:0 LISTENING 4 driverquery /v | findstr /i kbdflt2 kbdflt2.sys Unknown C:\Windows\System32\drivers\kbdflt2.sys EDR note: Process enumeration from user mode does not match kernel event telemetry.
Based on the exhibit, which malware type best explains the behavior?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Trojan
A trojan disguises itself as legitimate software, but the key clue here is concealment of system activity from user-mode tools.
B
Best answer
Rootkit
The exhibit shows a hidden listener associated with PID 4, an unsigned driver, and a mismatch between user-mode process enumeration and kernel telemetry. Those are classic rootkit indicators because rootkits operate at a low level to conceal processes, ports, or files from standard tools. The suspicious driver name and kernel-level inconsistency are especially strong clues that the malware is trying to hide itself from the operating system and defenders.
C
Distractor review
Logic bomb
A logic bomb waits for a condition or date before triggering a payload, such as deletion or encryption, which is not the main clue shown here.
D
Distractor review
Spyware
Spyware focuses on stealthy information collection, but the exhibit specifically shows kernel-level concealment and hidden listening services.
Common exam trap
Common exam trap: usable hosts are not the same as total addresses
Subnetting questions often tempt you into counting all addresses. In normal IPv4 subnets, the network and broadcast addresses are not usable host addresses.
Technical deep dive
How to think about this question
Subnetting questions test whether you can identify the network, broadcast address, usable range, mask and correct subnet. Slow down enough to calculate the block size correctly.
KKey Concepts to Remember
- CIDR notation defines the prefix length.
- Block size helps identify subnet boundaries.
- Network and broadcast addresses are not usable hosts in normal IPv4 subnets.
- The required host count determines the smallest suitable subnet.
TExam Day Tips
- Write the block size before choosing the subnet.
- Check whether the question asks for hosts, subnets or a specific address range.
- Do not confuse /24, /25, /26 and /27 host counts.

FAQ
Questions learners often ask
What does this SY0-701 question test?
CIDR notation defines the prefix length.
What is the correct answer to this question?
The correct answer is: Rootkit — The strongest clue is that user-mode tools do not see what the kernel telemetry detects, plus the hidden listener and unsigned driver. That is a classic rootkit pattern because rootkits alter or hide operating system views to evade detection. A rootkit may install a driver or kernel component that masks processes, sockets, or files. The discrepancy between tasklist, netstat, and EDR telemetry is what makes this more than ordinary malware. Why others are wrong: A trojan is malware disguised as something benign, but the exhibit is about stealth and concealment rather than disguise. A logic bomb depends on a trigger event such as a date or condition and would usually show a delayed destructive action. Spyware collects data quietly, but it does not typically create kernel-level hiding behavior or inconsistent system views like the ones shown here.
