Which of the following descriptions of stack topology connection methods is incorrect?

Question

Options

• ADepending on the stack connection method, the stack can form no connection topologies: link and ring.
• BUsing the directly-connected-related stack, it is recommended to use the ring connection method.
• CWhen stacking link utilization requirements are high, it is recommended to use the chain connection method.
• DWhen the stack member switches are far apart, chain connection can be used.

• A
  16% (10)
• B
  5% (3)
• C
  72% (46)
• D
  8% (5)

Explanation

Option C is incorrect because when stacking link utilization requirements are high, the ring connection method is recommended - not chain. Ring topology provides two data paths between any two switches, distributing traffic load and maximizing bandwidth, which is exactly what high-utilization environments need.

Why the other options are correct (and thus not the answer):

• A is correct: the two standard stack connection topologies are indeed link (chain) and ring.
• B is correct: for directly connected stack switches, ring is the recommended topology because it offers redundancy - if one link fails, traffic reroutes the other way around the ring.
• D is correct: when member switches are physically far apart, chain connection is practical because you avoid the cost and complexity of running cable back to complete the ring.

Memory tip: Think of it this way - Ring = Redundancy + high throughput (traffic has two directions to travel), while Chain = Distance + simplicity (easier to cable over long distances). Whenever you see "high utilization," your instinct should be ring, not chain.
