Zorluk: KolayMobile Device Wireless and Network Connectivity

A field technician is configuring network security settings on a corporate smartphone for a remote employee. The employee requires encrypted incoming email that synchronizes across all mobile devices, as well as secure web browsing. Which TWO of the following ports must be allowed through the network firewall to support these services?

  1. Port 993 for IMAP over SSL/TLSCevap
  2. Port 443 for HTTPSCevap
  3. C
    Port 80 for encrypted web browsing traffic
  4. D
    Port 110 for multi-device synchronized incoming email
  5. E
    Port 169 for mobile DHCP address assignments

Cevap

The correct options are Port 993 for IMAP over SSL/TLS and Port 443 for HTTPS.
Port 993 handles secure IMAP traffic, which allows users to synchronize incoming email messages and folder statuses across multiple mobile endpoints. Port 443 handles secure HTTPS traffic using SSL/TLS encryption for web browsing.

Adım Adım Çözüm

1
Determine the required secure incoming mail port that supports multi-device status synchronization.
IMAP over SSL/TLS (IMAPS) uses port 993.
IMAP keeps email stored on the server so read/unread flags and folders synchronize seamlessly across multiple mobile clients, while SSL/TLS ensures encryption.
2
Determine the standard network port for secure web communications.
HTTPS uses port 443.
HTTPS encrypts session traffic between the mobile web browser and web servers over transport layer security.
