Reinforce 100-150 concepts with active-recall study cards covering all 6 blueprint domains. Each card shows the question on the front and the correct answer with a full explanation on the back.
Flashcards work through active recall — the process of retrieving information from memory rather than passively re-reading it. Research consistently shows that active recall produces stronger, longer-lasting memory than re-reading study guides. For 100-150 preparation, this means flashcards are one of the highest-return study tools available.
Attempt recall first
Read the 100-150 question on each card, pause, and attempt to formulate the answer in your own words before revealing. This retrieval attempt — even if wrong — dramatically strengthens memory compared to immediately reading the answer.
Review wrong cards again
When you get a card wrong, note it and add it back to your review pile. Spaced repetition — seeing difficult cards more frequently — is the mechanism that makes flashcard study far more efficient than linear reading.
Study by domain
Group your 100-150 flashcard sessions by domain for the first 3–4 weeks. Master one domain before moving to the next. In the final week, shuffle all cards together to test cross-domain recall — which is what the real 100-150 exam requires.
Short sessions beat marathon reviews
20–30 flashcard cards per session, done daily, produces better retention than a single 200-card marathon session. Five short daily sessions per week over 4 weeks gives you over 400 total card reviews — enough to reliably pass 100-150.
Sample cards from the 100-150 flashcard bank. Read the question, think of the answer, then read the explanation below.
A network technician is troubleshooting a connectivity issue where a workstation can communicate with local devices but cannot access any resources on a different subnet. After verifying the IP address and subnet mask, which component should be investigated next to ensure the packet can leave the local segment?
The default gateway address configured on the workstation.
The default gateway is the router interface that forwards packets destined for remote subnets. If the workstation's default gateway is missing, incorrect, or unreachable, the packet cannot leave the local segment even though local communication works. Since IP and subnet mask are verified, the next logical check is the gateway configuration.
An administrator needs to subnet the 192.168.10.0/24 network into subnets that support at least 25 hosts each. Which CIDR mask provides the most efficient use of addresses while meeting the requirement?
/27
To support 25 hosts, the subnetwork must provide at least 27 usable IP addresses, accounting for network and broadcast IDs. The formula 2^n - 2 >= 25 indicates n=5 host bits are required, leaving 27 bits for the network portion. Using a /27 mask results in 30 usable hosts per subnet, which is the most efficient configuration compared to larger allocations that would waste addresses.
A network administrator observes that a workstation cannot ping its default gateway. The physical link light is active, and the local IP configuration appears correct. Which diagnostic step should be performed first to isolate the layer 2 connectivity issue?
Check the ARP table for the gateway IP address.
Verifying the ARP table is the most effective initial step when IP connectivity fails despite physical link status. It confirms whether the device can successfully resolve the MAC address of the default gateway, which is a prerequisite for layer 3 communication. If the ARP request fails, the issue is likely within the local broadcast domain, such as an incorrect VLAN assignment or a misconfigured trunk port on the connected switch.
A network administrator needs to connect a workstation to a Cisco switch. Which cabling standard and medium should be utilized to ensure full-duplex communication while preventing collision domains?
Category 6 twisted-pair cable with full-duplex settings
Category 6 twisted-pair cable with full-duplex settings is the correct combination because modern Ethernet switches support full-duplex on twisted-pair, which eliminates collisions by providing separate transmit and receive paths on different wire pairs. Cat 6 supports gigabit speeds at 100 meters and is the appropriate medium for a workstation-to-switch connection. Full-duplex operation removes the collision domain entirely on that link.
A network administrator needs to prevent unauthorized devices from connecting to switch ports. Which feature provides the most effective Layer 2 security by verifying the MAC address of the connected device against a database?
Port Security
Port Security allows administrators to secure access to ports by locking a specific MAC address to that port. This prevents unauthorized devices from gaining network access. In a Cisco enterprise environment, this is a fundamental defense-in-depth measure against unauthorized physical access. By restricting the number and identity of MAC addresses, the network remains resilient against simple spoofing or unauthorized hardware insertions, ensuring that only trusted endpoints communicate through the designated access layer infrastructure.
A network technician is tasked with connecting two distribution switches located in separate buildings 500 meters apart. Which media type should be selected to ensure reliable connectivity and high bandwidth without the need for repeaters?
Single-mode fiber optic cabling
Optical fiber provides the necessary distance capabilities for a 500-meter run, which significantly exceeds the 100-meter limit of standard copper UTP cabling. In an industrial or outdoor environment, fiber is also immune to electromagnetic interference from heavy machinery or power lines. Understanding media limitations ensures that network technicians select the appropriate physical layer components to maintain signal integrity.
The 100-150 flashcard bank covers all 6 official blueprint domains published by Cisco. Cards are distributed proportionally, so domains with higher exam weight have more cards.

Both flashcards and practice questions are evidence-based study tools. The difference is in what they train:
Flashcards — concept retention
Best for memorising definitions, acronyms, protocol behaviours, command syntax, and conceptual distinctions. Use flashcards to build the foundational vocabulary that 100-150 questions assume you know.
Best in: weeks 1–3
Practice tests — application
Best for applying concepts to realistic scenarios, eliminating distractors, and building exam stamina.100-150 questions test scenario reasoning — not just recall — so practice tests are essential.
Best in: weeks 3–6
The most effective 100-150 study plan combines both: use flashcards for the first 2–3 weeks to build conceptual foundations, then shift to practice tests and mock exams in the final 2–3 weeks to apply and benchmark that knowledge. Most candidates who pass on their first attempt use both tools.
Yes. Courseiva provides free 100-150 flashcards across all official exam domains. Every card includes the correct answer and a full explanation of why it is right and why the distractors are wrong. The platform also includes topic-based practice, mock exams, and readiness tracking — no account required.
Courseiva has 297+ original 100-150 flashcards across all 6 exam blueprint domains. New cards are added regularly as the question bank grows. All cards are checked against the official Cisco exam objectives, with editorial oversight from an experienced network and security engineer.
Courseiva flashcards are purpose-built for IT certification exams. Unlike generic flashcard platforms where content quality varies, every Courseiva card is mapped to the official 100-150 exam blueprint, written by engineers who hold the certification, and includes a full explanation of the correct answer and why the distractors are wrong. This explanation quality is what separates genuine learning from rote memorisation.
Courseiva is a web platform — an internet connection is required. For offline study, we recommend creating free Courseiva account, using the platform in your browser, and using your device's offline capabilities if your browser supports offline web apps.
