2.1 Explain characteristics of routing technologies.
Objective 2.1 sits in Network Implementation, which carries 20% of the Network+ 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.
Which characteristic best describes OSPF, according to RFC 2328?
The concept
OSPF is defined as an interior link-state routing protocol confined to a single Autonomous System.
Why this answer
RFC 2328's abstract states OSPF is a link-state routing protocol designed to run internal to a single Autonomous System, matching option A exactly.
- Correct: matches the abstract's description of OSPF as a link-state, single-AS protocol.
- BThis describes BGP, which exchanges reachability across Autonomous Systems using AS path information.
- CThis describes distance-vector protocols like RIP, not the link-state design OSPF uses.
- DThis mischaracterizes OSPF's transport and mechanism; OSPF is not defined by TCP-based session exchanges in the source.
Now you: objective 2.1 questions
No account needed. The explanation opens when you answer.
Sample question 1 of 3
A network administrator splits a single OSPF Autonomous System into multiple regions to limit the scope of link-state flooding and add another layer of routing protection. Which mechanism does this describe?
Sample question 2 of 3
What is the primary function of a BGP speaking system, as defined in RFC 4271?
Sample question 3 of 3
An ISP combines several customer prefixes into a single advertisement to reduce the number of routes sent to its peers. Which BGP-4 mechanism, described in RFC 4271, supports this behavior?
