So let’s get started!
Hardware
1. You are upgrading RAM in a laptop but notice only one slot is available. What RAM technology is being used here?
- A) DIMM
- B) SODIMM
- C) SIMM
- D) VRAM
Explanation:
Laptops use Small Outline Dual In-line Memory Modules (SODIMMs) that are physically smaller than desktop DIMMs to fit the compact hardware. SIMMs and VRAM are outdated legacy RAM types. So B is correct.
2. Which port uses a 15-pin connector and supports analog video output?
- A) DVI
- B) VGA
- C) HDMI
- D) DisplayPort
Explanation:
VGA (Video Graphics Array) uses a 15-pin DE-15 connector and can transmit analog component RGB video signals. So B is the right choice.
Networking
3. Which wired connectivity standard provides speeds up to 2.5 Gbps using existing CAT5e cabling?
- A) 802.11ac
- B) 802.11ax
- C) 802.3bz
- D) 802.11ay
Explanation:
802.3bz defines 2.5GBASE-T and 5GBASE-T Ethernet standards that enable multi-gigabit speeds over legacy CAT5e cabling. A, B, and D describe wireless protocols. Hence C is correct.
4. Which network troubleshooting tool pings multiple hops to trace the path packets take to reach a destination?
- A) ipconfig
- B) tracert
- C) nslookup
- D) netstat
Explanation:
tracert (traceroute) sends ICMP echo requests and records route hops between the source and destination. So B is the answer.
Mobile Devices
5. Which mobile device authentication method uses your unique physical characteristics?
- A) Password
- B) PIN
- C) Biometrics
- D) Pattern
Explanation:
Biometrics like fingerprints, iris/face recognition, and voice matching authenticate users based on their unique physical traits. So C is the right response.
6. Which protocol helps locate tags and stickers attached to objects using radio waves?
- A) NFC
- B) RFID
- C) Bluetooth
- D) ANT
Explanation:
RFID (Radio Frequency Identification) uses electromagnetic fields to read/write data to tags & stickers for tracking objects. Choice B is correct.
Troubleshooting
7. A user cannot print documents from their laptop connected to a wireless office network. What should you check FIRST?
- A) Default printer
- B) Network connectivity
- C) Printer drivers
- D) Spooler service
Explanation:
Since this issue occurs over Wi-Fi, the network connectivity should be verified first before investigating other print-related problems. So B is the right pick.
8. An end user reports their laptop runs extremely slow when multiple applications are open. What would be the BEST solution?
- A) Increase RAM
- B) Add a Solid State Drive (SSD)
- C) Replace the CPU
- D) Upgrade the graphics card
Explanation:
Adding an SSD will drastically improve read/write speeds and system responsiveness compared to traditional HDDs when multitasking. So choice B is correct.
IT Fundamentals
9. You need to securely erase all data from old hard drives before disposing them. Which method overwrites drive sectors with binary zeros?
- A) Degaussing
- B) Shredding
- C) Sanitizing
- D) Purging
Explanation:
Sanitizing (or clearing) overwrites all addressable locations with zeros to prevent data recovery. Choices A, B and D refer to other drive disposal techniques. Hence C is the answer.
10. Which cloud computing deployment model uses shared public infrastructure resources?
- A) Public Cloud
- B) Private Cloud
- C) Hybrid Cloud
- D) Community Cloud
Explanation:
A Public Cloud platform utilizes shared computing resources available online to the general public. So A is correct.
