HPE Aruba Certified Network Security Professional (ACNSP) — Question 11

What are two primary concerns regarding layer two loops in a redundant topology? (Choose two.)

Answer options

• A. routing loops
• B. costs associated with upgrading from copper to fiber
• C. multiple frame copies leading to instability of the MAC address table
• D. security issues with a redundant loop indicating to hackers that a back-door exists
• E. broadcast storms

Correct answer: C, E

Explanation

The correct answers, C and E, address the problems that arise from layer two loops, such as multiple copies of frames causing the MAC address table to become unstable and broadcast storms overwhelming the network. Options A, B, and D are not primary concerns in this context; routing loops pertain to layer three, upgrading costs are unrelated to loop stability, and security issues, while relevant, are not as critical as the instability and broadcast storms caused by layer two loops.
