CCNA Routing and Switching (legacy) — Question 133

What are three benefits of implementing VLANs? (Choose three.)

Answer options

• A. A higher level of network security can be reached by separating sensitive data traffic from other network traffic.
• B. A more efficient use of bandwidth can be achieved allowing many physical groups to use the same network infrastructure.
• C. A more efficient use of bandwidth can be achieved allowing many logical networks to use the same network infrastructure.
• D. Broadcast storms can be mitigated by decreasing the number of broadcast domains, thus increasing their size.
• E. Port-based VLANs increase switch-port use efficiency, thanks to 802.1Q trunks.
• F. VLANs make it easier for IT staff to configure new logical groups, because the VLANs all belong to the same broadcast domain.
• G. Broadcast storms can be mitigated by increasing the number of broadcast domains, thus reducing their size.

Correct answer: A, C, G

Explanation

The correct answers, A, C, and G, highlight the benefits of VLANs in terms of security, bandwidth efficiency, and managing broadcast domains. Option A emphasizes improved security through traffic separation, option C points out efficient bandwidth usage for logical networks, and option G correctly states that increasing broadcast domains helps reduce broadcast storms. Options B, D, E, and F are either incorrect or do not accurately describe the benefits of VLANs.
