2.6 Given a scenario, configure basic wired/wireless small office/home office (SOHO) networks.
Objective 2.6 sits in Networking, which carries 23% of the A+ Core 1 exam. The questions below are original, written from the official objective title above, and each explanation cites the CompTIA page it rests on.

A worked example
Shown solved, with the whole explanation open: this is what every question here carries.
A SOHO user's laptop cannot resolve a website's domain name to an address. The technician checks the setting that tells the laptop which server to contact for name lookups. Which setting is the technician checking?
The concept
A resolver on a client host must know the address of a name server to contact in order to resolve domain names.
Why this answer
The DNS server address is the setting that tells the client's resolver which name server to query for domain name lookups.
- AThe default gateway routes traffic off the local subnet but is not used for name resolution.
- Correct: the DNS server address is what the resolver uses to contact a known name server.
- CThe subnet mask defines the local network boundary and has no role in name resolution.
- DThe DHCP server address is used to obtain leased configuration, not to resolve domain names.
Now you: objective 2.6 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 2
A home office router's DHCP settings assign each device an address that expires after a set lease time and returns to the pool. Which allocation mechanism does this describe?
Sample question 2 of 2
Users on a small office network intermittently receive IP configurations from an unexpected subnet, causing connectivity failures. A technician finds an employee's personal router is plugged into the switch and also offering leases. What is the most likely cause?
