Question #16
A customer requires a hub-and-spoke Auto VPN deployment with two NAT-mode hubs with dual uplink connections and 50 remote sites with a single uplink connection.
How many tunnels does each hub need to support?
How many tunnels does each hub need to support?
- A52
- B54
- C100
- D104
Correct Answer:
C
C
GPT-4o - Answer
The user provided calculation in comment 1 reflects the logic for the proper tunnel configuration but incorrectly sums the total to 104. The correct formula and execution would lead to an answer of 100, not 104, which aligns with the assumed correct answer (C). Each NAT-mode hub forms two tunnels with the other hub due to dual uplink connections and creates two tunnels to each of the 50 remote sites, one for each of its two links. Hence, the formula correctly captures the VPN tunnel requirements, making (C) 100 the right choice.
Question #17
How is high-availability supported for Cisco Meraki devices?
- AOnly the MX Security Appliances that use VRRP support high availability.
- BAn active/active high-availability pair is recommended for MX Security Appliances.
- CThe MX Security Appliances and MS Series Switches that use VRRP support an active/passive high-availability pair.
- DThe MX Security Appliances and MS Series Switches that use HSRP support an active/passive high-availability pair.
Correct Answer:
A
A
GPT-4o - Answer
Alright, here’s the deal: High availability in Cisco Meraki devices, particularly the MX Security Appliances, is anchored on using the Virtual Router Redundancy Protocol (VRRP). This supports a high-availability configuration that’s specifically active/passive rather than active/active. So, the MX lines up with VRRP for that seamless failover when the primary unit kicks the bucket, ensuring minimal disruption. Super important for keeping your network reliable and ready to bounce back!
Question #18
Which Cisco Meraki product must be deployed in addition to Systems Manager so that Systems Manager Sentry enrollment can be used?
- AMS Switch
- BMeraki Insight
- CMR Access Point
- DMV Smart Camera
Correct Answer:
C
C
GPT-4o - Answer
The MR Access Point is essential when configuring Systems Manager Sentry enrollment. It allows seamless and secure onboarding of devices to a network through the configuration on the Access control page in a MR network's settings. By utilizing Sentry enrollment, devices like Android, iOS, macOS, and Windows can easily be managed and provided with necessary configurations, enhancing both security and efficiency in managing BYOD environments. This capability isn't supported by other devices listed like MS Switch, Meraki Insight, or MV Smart Camera, making the MR Access Point the correct and only option.
Question #19
Which information do the MXs in a High Availability pair share?
- Aspanning-tree state
- Btime synchronization state
- CDHCP association database
- Dstateful firewall database
Correct Answer:
A -
A -
GPT-4o - Answer
The correct answer is indeed A, focusing on the Spanning Tree Protocol (STP) state. In a high availability (HA) configuration, MX devices share STP states to prevent loops and ensure proper network topology after a failover event occurs. This enables the secondary MX to seamlessly take over in the event of a primary device failure, maintaining consistency in traffic flow and network configuration without requiring re-computation of the existing spanning tree topology.
