NEW QUESTION # 39
Which type of memory stores the decompressed form of Cisco IOS Software and the running configuration?
Answer: A
Explanation:
The decompressed form of Cisco IOS Software and the running configuration are stored in DRAM (Dynamic Random-Access Memory) on Cisco devices. DRAM is used as the main memory for the device, where the operating system runs and the running configuration is stored. When a Cisco device boots up, the IOS image is decompressed and loaded into DRAM, and the running configuration is also held in this memory type. It's important to note that DRAM is volatile memory, which means its contents are lost when the device is powered off or restarted12.

NEW QUESTION # 40
ESD is the sudden and momentary electric current that flows between two objects at different electrical potentials, caused by direct contact or induced by an electrostatic field. Which three tools are used to avoid ESD? (Choose three.)
Answer: C,D,F
Explanation:
Electrostatic Discharge (ESD) poses a significant risk to delicate electronic components. Here's why the correct answers are essential tools for ESD protection:
Antistatic Mat: Provides a grounded surface to work on, dissipating static buildup from your body and the components you're handling.
ESD Wrist Strap: When connected to a grounding point (often on the antistatic mat), this strap creates an electrical path to safely discharge static electricity from your body.
Antistatic Bag: These special bags are designed to shield sensitive components from static charge, crucial for storing and transporting electronic parts.
Why other options are incorrect:
Negative static bag, negative static mat: These terms don't exist in standard ESD protection practices. The focus is on creating a grounded environment to neutralize static charges.
Latex gloves: While they offer insulation, they can actually generate static electricity, increasing the risk of ESD damage.
