Zorluk: OrtaMobile Device Synchronization and Cloud Integration

A network administrator is provisioning enterprise mobile devices for field employees who require secure, real-time synchronization of corporate email, contacts, and calendar items over public Wi-Fi networks. Which of the following protocols and configurations should the administrator implement on the mobile clients to meet these requirements? (Select TWO.)

  1. Exchange ActiveSync (EAS) operating over secure HTTPS (TCP port 443)Cevap
  2. IMAP over SSL/TLS (IMAPS) operating over TCP port 993Cevap
  3. C
    POP3 operating over TCP port 110 for multi-device email status synchronization
  4. D
    Unencrypted IMAP over TCP port 143 secured using IMSI subscriber payload validation
  5. E
    Full Mobile Device Management (MDM) device wiping triggered over TCP port 80

Cevap

Exchange ActiveSync (EAS) operating over secure HTTPS (TCP port 443) and IMAP over SSL/TLS (IMAPS) operating over TCP port 993.
Exchange ActiveSync (EAS) over port 443 provides comprehensive push synchronization for email, calendar, and contacts over an encrypted SSL/TLS connection. IMAP over SSL/TLS (IMAPS) on port 993 secures incoming mail retrieval while maintaining synchronized mailbox states across multiple mobile devices.

Adım Adım Çözüm

1
Identify the synchronization data types and security constraints required.
The scenario requires multi-device status synchronization of email, contacts, and calendar data over untrusted connections.
Synchronization over public networks must use encrypted protocol channels.
2
Evaluate corporate email and synchronization protocol capabilities.
Exchange ActiveSync natively synchronizes email, contacts, and calendar push items securely via port 443. IMAPS (port 993) securely syncs email folder states across multiple clients.
Both protocols support multi-device synchronization and encrypted transport.
