ECMS Network Monitoring and Troubleshooting 2 — Questions and Answers
Question 1: What Meraki feature provides historical data on WAN uplink performance including latency, jitter, and loss over time?
- Real-time packet capture only
- WAN uplink performance history under Security & SD-WAN > Appliance Status (Correct answer)
- Organization > Summary Report
- GSC integration dashboard
Correct answer: WAN uplink performance history under Security & SD-WAN > Appliance Status
The Meraki dashboard graphs WAN uplink performance metrics including latency, jitter, and packet loss over 2 hours to 30 days under the Appliance Status page.
Question 2: In Meraki troubleshooting, what information does the 'ARP Table' Live Tool on an MX appliance provide?
- A list of all firewall rules matching recent traffic
- IP-to-MAC address mappings currently known by the MX from ARP cache (Correct answer)
- The routing table with next-hop information
- DHCP leases currently assigned by the MX
Correct answer: IP-to-MAC address mappings currently known by the MX from ARP cache
The ARP table Live Tool shows the current ARP cache on the MX, revealing which IP addresses have been resolved to MAC addresses, useful for verifying host reachability.
Question 3: What does the Meraki MX 'Flow' data, visible in the traffic analytics section, represent?
- Switch VLAN trunk statistics
- Detailed per-application and per-destination traffic flows through the MX (Correct answer)
- CPU and memory utilization of the MX appliance
- VPN tunnel negotiation logs
Correct answer: Detailed per-application and per-destination traffic flows through the MX
Traffic analytics on the Meraki MX uses deep packet inspection to display per-application, per-client, and per-destination traffic flows, enabling visibility into bandwidth consumption.
Question 4: What Meraki feature enables administrators to generate scheduled summary reports of network activity, clients, and device status?
- Live dashboard auto-export
- Summary Report emailed on a schedule from Organization > Summary Report (Correct answer)
- Syslog export to external server
- Manual CSV download only
Correct answer: Summary Report emailed on a schedule from Organization > Summary Report
Meraki's Summary Report feature generates and emails periodic reports on network usage, top clients, application traffic, and device health on a configurable schedule.
Question 5: When troubleshooting a wireless client that is unable to obtain an IP address via DHCP, which Meraki tool provides the most direct insight?
- Air Marshal WIDS alerts
- Client detail page Event Log showing DHCP request and response events (Correct answer)
- RF profile channel utilization graph
- Organization-level firmware status
Correct answer: Client detail page Event Log showing DHCP request and response events
The client detail page Event Log shows DHCP discover, offer, request, and acknowledge messages, making it easy to identify where the DHCP process is failing.
Question 6: Which Meraki network health feature provides a single score summarizing the overall wireless performance experience for clients?
- Uplink health score
- Wireless Health Score (Correct answer)
- Client satisfaction (CSAT) rating
- Network availability percentage
Correct answer: Wireless Health Score
Meraki Wireless Health calculates a health score based on association failures, DHCP failures, and DNS failures, giving a quick overall picture of wireless client experience.
