質問 1：
An administrator is configuring an ION 2000 device for a deployment where high availability is required, but the site has only a single internet circuit. The administrator configures a Bypass Pair (Fail-to-Wire) on ports 1 and 2 connecting the ISP modem to the legacy firewall.
If the ION device loses power, what is the resulting behavior of the traffic flowing through this Bypass Pair?
A. The internal relay closes, physically bridging Port 1 and Port 2, allowing traffic to flow transparently between the modem and firewall.
B. The device reboots into "Safe Mode" and acts as a Layer 2 switch.
C. Traffic is rerouted to the LTE modem automatically.
D. Traffic is blocked to prevent uninspected packets from entering the network (Fail-to-Block).

For the time duration shown in the graph, what are two inferences about the site's traffic that can be made?
(Choose two.)
A. Using Carrier-1 as the WAN path may have switched over to Carrier-2.
B. Using Carrier-2 as the WAN path may have experienced some performance degradation.
C. Using Carrier-2 as the WAN path may have switched over to Carrier-1.

質問 5：
When troubleshooting an issue at a site that is running on two cellular links from two carriers, the operations team shared some evidence shown in the graph below:
(SNR Graph showing Carrier-1 in blue dropping to near 0 dB and Carrier-2 in green staying relatively stable between 4.5 dB and 6.5 dB)

For the time duration shown in the graph, what are two inferences about the site's traffic that can be made?
(Choose two.)
A. Using Carrier-1 as the WAN path may have switched over to Carrier-2.
B. Using Carrier-2 as the WAN path may have experienced some performance degradation.
C. Using Carrier-2 as the WAN path may have switched over to Carrier-1.
D. Using Carrier-1 as the WAN path may have experienced some performance degradation.

質問 7：
A network installer is attempting to claim a new ION device using the "Claim Code" method. The device is connected to the internet, but the status in the portal remains stuck at "Claimed" and does not transition to
"Online". The installer connects a laptop to the LAN port of the ION and can successfully browse the internet, confirming the uplink is active.
What is the most likely cause of the device failing to reach the "Online" state?
A. The "Circuit Label" has not been applied to the WAN interface.
B. The device is missing the "Site" assignment in the portal.
C. The upstream firewall is blocking outbound TCP port 443 or UDP port 123 (NTP).
D. The device has not yet downloaded the latest software image.
