What is the default IP range of Sync network (with no increment)?

Question

Options

• AThe same as Management network
• B198.51.100.0
• C192.0.2.0
• D192.168.1.0

• A
  5% (3)
• B
  2% (1)
• C
  89% (49)
• D
  4% (2)

Explanation

Option C (192.0.2.0) is the correct default IP range for the Sync network because this address block (192.0.2.0/24, known as TEST-NET-1 per RFC 5737) is the vendor-designated default for the Sync interface when no address increment is applied - meaning it uses the base network address without any automatic offset added to differentiate multiple sync networks.

Option A is wrong because the Management network occupies its own separate default range (typically 192.168.1.0/24); Sync and Management networks are intentionally distinct to isolate synchronization traffic from administrative traffic. Option B (198.51.100.0) is TEST-NET-2 per RFC 5737 - a plausible-looking distractor since it shares the same "documentation reserved" category as the correct answer, but it is not the default for this interface. Option D (192.168.1.0) is the common Management network default, making it a strong distractor - test-takers who confuse the two networks will choose this.

Memory tip: Think "C for ConfigSync, C for the first Class of documentation addresses" - 192.0.2.0 is TEST-NET-1, the first (lowest) reserved documentation block, matching Sync as the primary inter-device communication channel.
