The answer is that the motherboard's chipset does not support that CPU generation. Even when the physical socket, such as LGA 1200, matches, the chipset controls power delivery, voltage regulation, and the microcode needed to recognize and run the processor. A motherboard with an older chipset like the H410 may physically accept a newer 11th-gen CPU, but it lacks the necessary firmware and electrical support to operate it. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding that CPU compatibility is a two-part requirement: socket shape and chipset generation. A common trap is assuming any CPU with the same socket will work, but the exam expects you to know that the chipset must explicitly list the CPU in its supported CPU list. For a memory tip, remember “Socket fits, chipset permits”—just because it drops in doesn’t mean it boots in.
220-1101 CPU Practice Question
This 220-1201 practice question tests your understanding of cpu. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 upgrading a workstation and notices that the new CPU is not listed in the motherboard's supported CPU list. The motherboard uses an LGA 1200 socket. What is the most likely issue?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The motherboard's chipset does not support that CPU generation
CPU compatibility depends on both socket and chipset. Even with the correct socket, the chipset may not support the CPU's power delivery or microcode. This question tests deeper knowledge of motherboard-CPU compatibility beyond just the socket.
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.
✗
The CPU is physically too large for the socket
Why it's wrong here
LGA 1200 is a standard size; physical fit is not the issue if the socket matches.
✓
The motherboard's chipset does not support that CPU generation
Why this is correct
The chipset must be compatible with the CPU's generation; otherwise, the system may not boot or may be unstable.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
The CPU requires more power than the motherboard can provide
Why it's wrong here
While possible, the chipset compatibility is the primary reason for not being on the supported list.
✗
The CPU is a server-grade processor not meant for workstations
Why it's wrong here
Server CPUs often use different sockets; an LGA 1200 CPU is typically consumer/workstation grade.
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.
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.
