Zorluk: OrtaMobile Device Wireless and Network Connectivity

A systems administrator is deploying cellular-enabled tablets to field service technicians. The tablets must maintain consistent email folder states and read status across multiple mobile devices while connecting to the corporate 2.4 GHz wireless network in warehouses without experiencing co-channel interference. Which TWO of the following configuration choices or procedures should the administrator implement?

  1. Configure mobile email accounts using IMAP over SSL/TLS to enable multi-device mailbox synchronization.Cevap
  2. Configure the 2.4 GHz wireless access points to use non-overlapping channels 1, 6, and 11.Cevap
  3. C
    Configure corporate email using POP3 over port 110 so messages are removed from the server after download.
  4. D
    Assign adjacent 2.4 GHz wireless channels 2, 3, and 4 across neighboring access points to maximize coverage.
  5. E
    Provide the cellular service provider with each tablet's IMSI to register the physical hardware on the mobile network.

Cevap

The administrator should configure mobile email accounts using IMAP over secure ports to maintain multi-device state synchronization, and set 2.4 GHz wireless access points to non-overlapping channels 1, 6, and 11 to eliminate co-channel interference.
IMAP is designed specifically for multi-device email synchronization because it maintains all messages and folder flags directly on the central mail server. Additionally, configuring 2.4 GHz Wi-Fi networks on channels 1, 6, and 11 prevents wireless frequency overlap and signal degradation.

Adım Adım Çözüm

1
Evaluate the email synchronization requirement across multiple devices.
IMAP (Internet Message Access Protocol) leaves messages on the mail server and synchronizes status (read, unread, deleted) across all user devices. POP3 downloads messages locally to a single device and breaks multi-device access.
Field technicians need access to consistent email status on all their mobile devices.
2
Evaluate the 2.4 GHz wireless channel deployment requirement.
The 2.4 GHz Wi-Fi band consists of 11 channels in North America (13 globally), but only channels 1, 6, and 11 do not overlap with one another. Using adjacent channels like 2, 3, or 4 causes destructive channel overlap.
Non-overlapping channels ensure stable wireless network connectivity for mobile devices in high-density warehouse environments.
