The answer is to recommend adding a SO-DIMM module of the same type and speed as the soldered RAM. This is correct because the laptop has an empty SO-DIMM slot, allowing a capacity upgrade that will improve multitasking performance, even though mixing soldered and modular RAM may force single-channel memory operation—the capacity gain outweighs the slight performance loss from single-channel mode. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of laptop memory upgrade constraints, specifically that soldered RAM cannot be removed, so you must match the SO-DIMM’s DDR generation and speed to the existing soldered memory. A common trap is assuming you must replace the soldered RAM or that dual-channel operation is mandatory; in reality, adding a mismatched or slower module can cause instability or reduced performance. Remember the mnemonic “Match the batch, slot the slot” to recall that the new SO-DIMM should match the soldered RAM’s type and speed for best compatibility.
220-1101 RAM Practice Question
This 220-1201 practice question tests your understanding of ram. 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 user complains that their laptop, which has 8 GB of RAM soldered on the motherboard, is running slowly when multitasking. They ask if they can add more RAM. The laptop has one empty SO-DIMM slot. What is the best recommendation?

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Recommend adding a SO-DIMM module of the same type and speed as the soldered RAM.
The laptop has a single empty slot, so adding a SO-DIMM module will increase total RAM. However, mixing a soldered module with a SO-DIMM may force single-channel operation, but the capacity gain outweighs this. The technician should recommend adding a compatible DDR4 or DDR5 SO-DIMM (depending on laptop) to improve performance.
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.
✗
Advise the user to replace the laptop because soldered RAM cannot be upgraded.
Why it's wrong here
While soldered RAM cannot be replaced, an empty slot allows adding more RAM, so an upgrade is possible.
✓
Recommend adding a SO-DIMM module of the same type and speed as the soldered RAM.
Why this is correct
Adding a matching SO-DIMM will increase total RAM and likely improve multitasking performance.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Suggest removing the soldered RAM and replacing it with a larger module.
Why it's wrong here
Soldered RAM is not removable; it is permanently attached to the motherboard.
✗
Tell the user to install two SO-DIMM modules for dual-channel.
Why it's wrong here
There is only one empty slot, so only one module can be added; dual-channel may not be possible.
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.

Variation 1. A technician is tasked with upgrading the RAM in a laptop that uses SO-DIMM modules. The laptop currently has 4 GB of RAM soldered on the motherboard and one empty SO-DIMM slot. The technician installs an 8 GB SO-DIMM, but the system only reports 8 GB total. What is the most likely reason?
hard
A.The SO-DIMM module is incompatible with the laptop's chipset.
B.The soldered RAM is faulty and has been disabled.
✓ C.The laptop's BIOS is configured to use only the SO-DIMM slot when populated.
D.The SO-DIMM is not seated properly in the slot.
Why C: Some laptops with soldered RAM have a limitation where the SO-DIMM slot cannot be used simultaneously with the onboard memory, or the system may disable the onboard RAM when a module is installed. This is a design constraint, not a hardware failure.
