Objective 2.6

220-1201

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.

2-6Networking

In DHCP address allocation, which mechanism assigns a permanent IP address to a client that does not expire?

Dynamic allocation: a network address assigned for a limited period of timeDynamic allocation puts a timer on the address and reclaims it when the lease runs out, which is the opposite of what the stem asks for.
BOOTP relay allocation: an address forwarded through an intermediate relay agentA BOOTP relay agent carries requests across a subnet boundary and hands out nothing itself.
Manual allocation: a network address chosen and assigned by an administratorManual allocation is settled by an administrator in advance.
Automatic allocation: a permanent network address assigned to a client hostCorrect · your answerCorrect: automatic allocation is the term for a permanently assigned address.

Correct.

Concept

The three ways a server can issue an IP differ on one axis: who picks the value, and for how long the lease holds. One is picked by the server and never expires, one is picked by the server and runs on a timer, one is picked by a person in advance.

Why D

Automatic allocation is the mechanism defined for assigning a client a permanent IP address that does not expire.

Source

In "automatic allocation", DHCP assigns a permanent IP address to a client.

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?

Sample question 2 of 3

2-6Networking

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 3 of 3

2-6Networking

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?
