問題文
At one branch the devices stay online in the dashboard, but saved changes take minutes to reach them, a firmware upgrade never starts, and wireless clients that authenticate against Meraki are turned away. The status page of the appliance reports that the cloud connection is running on the backup path. Which explanation fits every symptom?
選択肢
- The organization is inside the thirty day window after its expiration date, so the cloud holds management back until License Info is green.
- The tunnel fell back to HTTP and HTTPS because UDP 7351 is not permitted outbound, and Meraki authentication never travels over that fallback.
- The uplink monitor is failing its ICMP and HTTPS tests toward 8.8.8.8, so the appliance keeps moving the tunnel to its second uplink.
- The upstream firewall is dropping UDP 53 toward the DNS server on VLAN 20, so the tunnel cannot resolve the names of the Meraki servers.
