8 real 220-1101 flashcards, sampled across every domain the exam tests. Each concept card is paired with the misconception card built from the tempting wrong answer - the trap most decks skip. No account, no card.
The full deck has 488 flashcards. For a domain-by-domain breakdown and a study plan, read the 220-1101 study guide.
A phone's battery suddenly drains far faster with no change in usage. What is the first diagnostic step, before touching hardware?
Check the built-in battery usage statistics, which attribute power draw to specific apps and services. This identifies the true cause first, matching the identify-the-problem step. Replacing the battery or resetting the device acts before the problem is known and can be both unnecessary and destructive.
A sudden change in runtime always means the cell has reached its charge-cycle limit, so replace the battery straight away.
Tempting because an ageing cell is a real cause of drain, but swapping hardware before any diagnosis skips the identify-the-problem step, and the absolute claim that it is always the cell ignores common software causes.
Terminating a 1 Gbps twisted-pair Ethernet drop: which modular plug lands all the conductors the link needs, and why?
The 8P8C RJ-45. Gigabit Ethernet transmits over all four twisted pairs, and only the eight-position RJ-45 lands all eight conductors. The six-position RJ-11 exposes just the centre positions used for telephony.
RJ-11, the six-position plug, is fine for terminating a copper run feeding a desktop network adapter.
Tempting because RJ-11 looks like a smaller Ethernet plug and uses the same crimp tooling, but it is a six-position telephone connector and will not carry a Gigabit Ethernet link.
How do TCP and UDP differ as transport-layer protocols?
TCP is connection-oriented: it runs a three-way handshake and uses sequence numbers, acknowledgements, and retransmission to deliver an ordered, reliable byte stream. UDP is connectionless, sending independent datagrams with lower overhead but no acknowledgement or delivery guarantee.
UDP opens a session with a three-way handshake and retransmits lost segments, while TCP just fires off datagrams with no acknowledgement.
The attributes are reversed. The handshake, acknowledgements, and retransmission belong to TCP, not UDP. UDP is the lightweight connectionless protocol that sends datagrams without acknowledgement.
How many pins does a standard DDR4 SODIMM have, and how does that set it apart from DDR3 SODIMM?
A DDR4 SODIMM has 260 pins. JEDEC assigns each memory generation a distinct pin count so incompatible modules cannot seat; DDR3 SODIMM is 204 pins by comparison.
A DDR4 SODIMM uses 204 pins, the same as a laptop DDR3 module.
204 is a genuine SODIMM pin count, but it belongs to DDR3 SODIMM, not DDR4. DDR4 SODIMM is standardised at 260 pins, so 204 is the wrong generation.
