A network administrator is configuring secure mobile email client settings and troubleshooting wireless network connectivity for company-issued smartphones. Users report that when connected to the corporate guest Wi-Fi network, their mail applications fail to send outgoing messages and their devices display an IP address of 169.254.11.45. Which of the following actions should the administrator perform to resolve these issues? (Select TWO.)
- Reconfigure the outgoing mail server settings to use SMTP over TLS on port 587 instead of unencrypted port 25.Answer
- Investigate the local DHCP server connectivity and pool scope on the guest Wi-Fi network to resolve the self-assigned address allocation.Answer
- CReassign the 2.4 GHz Wi-Fi access points from channel 6 to channel 4 to minimize channel overlap on the guest network.
- DUpdate the International Mobile Equipment Identity (IMEI) number in the mail client account configuration settings.
- ESwitch the email protocol configuration from IMAP to POP3 to maintain multi-device folder state synchronization.
Answer
The administrator must reconfigure the outgoing mail server settings to use SMTP over TLS on port 587 and investigate the local DHCP server and scope availability on the guest Wi-Fi network.
The correct actions are updating the outgoing mail configuration to secure SMTP port 587 (which avoids guest network port 25 blocks) and checking DHCP server connectivity because the 169.254.x.x address signifies an APIPA failure caused by missing DHCP leases.
Step-by-Step Solution
Key Concept
Mobile network troubleshooting involves recognizing APIPA IP ranges as DHCP reachability failures and using standard secure mail ports (SMTP/TLS port 587) for mobile messaging client configuration.
