MS Switching and Network Segmentation Flashcards

What Meraki MS capability provides automatic VLAN assignment based on 802.1X authentication results from a RADIUS server?

Answer: Dynamic VLAN assignment via RADIUS attributes

When 802.1X authentication succeeds, the RADIUS server can return a VLAN ID attribute that Meraki MS uses to dynamically place the port into the appropriate VLAN.

What is the function of 'Link Aggregation (LAG)' on Meraki MS switches?

Answer: It combines multiple physical ports into a single logical link for increased bandwidth and redundancy

Link aggregation (IEEE 802.3ad LACP) combines multiple physical switch ports into one logical link, increasing bandwidth capacity and providing fault tolerance if one member link fails.

Which Meraki dashboard feature provides a topology view showing how MS switches are interconnected with other Meraki devices?

Answer: Monitor > Topology

The Meraki Monitor > Topology view automatically discovers and displays the physical connections between Meraki switches, APs, and MX appliances using LLDP data.

What Meraki MS feature helps prevent rogue DHCP servers from distributing addresses on the network?

Answer: DHCP snooping

DHCP snooping on Meraki MS switches validates DHCP messages and only forwards DHCP offers/acknowledgments received on trusted (uplink) ports, blocking unauthorized DHCP servers.

In Meraki switching, what does 'Dynamic ARP Inspection (DAI)' protect against?

Answer: ARP poisoning/spoofing attacks where a malicious device sends falsified ARP replies

DAI intercepts ARP packets and validates them against the DHCP snooping binding table, dropping ARP packets with IP-to-MAC mappings that don't match the binding database.

What Meraki MS feature allows administrators to disable or enable switch ports on a time schedule?

Answer: Port scheduling (access control by time)

Meraki port scheduling allows administrators to define time-based schedules that automatically enable or disable switch ports during specified hours or days.
