CCNA sampleQuestion 1 of 10
IP ConnectivityYou see the following entry in a router's routing table: 'O 192.168.10.0/24 [110/20] via 10.1.1.2, 00:00:12, FastEthernet0/0'. What does the 'O' signify in this routing table entry?
How this CCNA practice works
Every question is written against the current 200-301 blueprint and reviewed before it enters the bank. The explanation tells you why the correct answer wins and why the distractors fail, which is the part that actually moves your score — knowing an answer is right is less useful than knowing why the other three are wrong.
