- A
Puncture the battery to release the pressure, then throw it in the trash.
Why wrong: Puncturing a lithium-ion battery can cause a fire or chemical leak; it is dangerous and not environmentally responsible.
- B
Place it in a fireproof container and contact a hazardous waste disposal service.
This method minimizes fire risk and ensures the battery is disposed of according to environmental regulations.
- C
Put it in a sealed plastic bag and put it in the regular recycling bin.
Why wrong: Regular recycling bins are not designed for hazardous batteries, and they can cause fires at recycling facilities.
- D
Freeze the battery to stop the swelling, then dispose of it in the trash.
Why wrong: Freezing does not neutralize the hazard, and throwing it in the trash is still illegal and unsafe.
Quick Answer
The correct answer is to place the swollen lithium-ion battery in a fireproof container and contact a hazardous waste disposal service. This is the safest and most environmentally sound way to handle a swollen battery because a damaged lithium-ion cell is a severe fire hazard, prone to thermal runaway where internal short circuits generate intense heat and flammable gases. Proper containment prevents ignition, while professional disposal ensures the toxic materials are recycled or neutralized without contaminating the environment. On the CompTIA A+ Core 2 220-1202 exam, this question tests your knowledge of operational procedures for environmental safety and hazard prevention, often appearing in the "Safety" domain. A common trap is choosing to simply recycle it with regular electronics or discharge it first, both of which are dangerous with a swollen battery. Remember the memory tip: "Swollen means call the pro—fireproof it and let them go."

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Place it in a fireproof container and contact a hazardous waste disposal service.
A swollen lithium-ion battery is a fire hazard and must be handled with care. Placing it in a fireproof container and contacting a hazardous waste facility ensures safe disposal. This question emphasizes the importance of proper battery disposal to prevent fires and environmental contamination.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Why it's wrong here
Freezing does not neutralize the hazard, and throwing it in the trash is still illegal and unsafe.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related 220-1202 NAT questions on configuration and troubleshooting.
