A network technician is testing a new SSID for a branch office. They are able to connect, get an IP address, and resolve DNS names. However, they are not able to browse the internet.
On the existing SSID at the branch, connectivity to the internet works as expected on the same VLAN as the new SSID. The wireless client should have received a new role to allow internet access.
What should the network technician verify to ensure both SSIDs function in a similar way?
When a network technician encounters an issue where a new SSID does not allow internet access despite successful connectivity and DNS resolution, they should verify the firewall policies associated with the new SSID. The firewall policies must include rules that permit traffic to and from the internet and should be correctly ordered to ensure that they are applied as intended. Since the existing SSID functions correctly, comparing the firewall rules between the two can be a useful method of troubleshooting.
When does the 802.1x authentication process begin when connecting to a secured enterprise mode WLAN?
The 802.1x authentication process begins after the client device completes the 802.11 association with the access point but before the WPA 4-Way Handshake. This is part of the EAP (Extensible Authentication Protocol) process, which authenticates the device before allowing full network access.
You have been asked to troubleshoot failed connectivity between a local subnet in the HQ Office and a remote subnet in the Branch Office. PC1 is unable to ping PC2.
Use the provided topology and show command output to identify the reason for the failure:
Using the provided topology and show command output, it can be determined that L3-SW-2 in the Branch Office does not have a route to reach the subnet where PC1 resides (192.168.1.0/24 in the HQ Office). L3-SW-1 in the HQ Office has a route to the Branch Office subnet (172.16.1.0/24), but without the reciprocal route on L3-SW-2, traffic from the Branch Office will not be able to reach the HQ Office subnet, hence PC1 cannot ping PC2.
What is indicated by a flashing amber global status indicator LED on an Aruba CX6200M?
A flashing amber global status indicator LED on an Aruba CX6200M switch typically indicates that the switch has encountered a fault, but it is recoverable. This LED behavior serves as an alert to the network administrator that an issue needs to be addressed, but it does not necessarily mean that the switch is inoperable.
You have physical access to an Aruba CX-Switch with unknown/lost credentials. What are the possible steps to rebuild the credentials? (Select two.)
To regain access to an Aruba CX switch when credentials are unknown or lost, one can press and hold the clear button, then power cycle the switch to reset the password. Additionally, using the boot profile 0 at the boot loader menu can be used to bypass the current startup configuration, which may include the unknown credentials.
