Difficulty: MediumMobile Device Wireless and Network Connectivity

A network administrator is manually configuring email synchronization and wireless network settings on corporate mobile tablets. The tablets must sync mailbox states across multiple devices seamlessly and connect to a 2.4 GHz Wi-Fi network without co-channel interference near existing access points using Channel 1. Which TWO configurations should the administrator select to fulfill these requirements?

  1. Configure the mobile email client using IMAP (Internet Message Access Protocol) for real-time multi-device mailbox state synchronization.Answer
  2. Set the 2.4 GHz wireless access points to operate on non-overlapping channels such as Channel 6 or 11.Answer
  3. C
    Configure the mobile email client using POP3 (Post Office Protocol 3) to manage multi-device mailbox folder states.
  4. D
    Set the 2.4 GHz wireless access points to operate on Channel 2 to maintain adjacent channel proximity with Channel 1.
  5. E
    Configure the secure IMAP incoming mail service to communicate over standard unencrypted web traffic Port 80.

Answer

The administrator must configure the mobile email clients to use IMAP for multi-device status synchronization and set the 2.4 GHz Wi-Fi access points to non-overlapping channels such as Channel 6 or 11.
IMAP allows email messages to remain stored on the server so that inbox updates, flags, and folder changes synchronize seamlessly across multiple mobile endpoints. Furthermore, selecting 2.4 GHz Wi-Fi Channel 6 or 11 avoids channel overlap with existing access points using Channel 1, ensuring optimal wireless throughput without co-channel interference.

Step-by-Step Solution

1
Evaluate the mail protocol requirement for multi-device synchronization.
Identify that IMAP retains emails on the server and synchronizes folder states across multiple devices, whereas POP3 downloads messages locally to a single endpoint.
Choosing IMAP ensures consistent read, unread, and flagged states regardless of which device the user operates.
2
Evaluate the 2.4 GHz Wi-Fi channel assignment requirement.
Identify non-overlapping channels in the 2.4 GHz spectrum (1, 6, and 11).
Because Channel 1 is in use nearby, configuring Channel 6 or 11 prevents co-channel and adjacent-channel interference, whereas adjacent channels like Channel 2 cause overlapping frequency crosstalk.

Key Concept

Mobile email protocol selection for multi-device synchronization and non-overlapping 2.4 GHz Wi-Fi channel allocation.
