Free 220-1101 / 220-1102 sample questions

1. A technician is replacing the charging cable for a newer Android flagship phone that supports fast charging and high-speed data transfer. Which connector should the replacement cable use?

   • A. USB-C, a reversible connector that supports USB Power Delivery and high-speed data
   • B. Lightning, the proprietary connector Apple uses on iPhone and older iPads
   • C. Mini-USB, the legacy connector found on older digital cameras and MP3 players
   • D. Micro-USB, the connector used on most budget phones manufactured before 2017
   Show answer

   Correct: A. Modern Android flagships use USB-C, which is reversible and supports USB Power Delivery for fast charging plus high data rates. Lightning is incorrect because it is Apple-proprietary, not used on Android. Mini-USB and Micro-USB are older, slower standards that lack Power Delivery and are not found on current flagship devices.

2. An administrator must push email settings, passcode requirements, and remote-wipe capability to hundreds of corporate-owned tablets from a central console. Which solution accomplishes this?

   • A. Mobile device management (MDM) such as Intune or Jamf for centralized policy enrollment
   • B. Asking each user to manually configure the settings from the device Settings menu
   • C. A group policy object linked to the domain that targets the tablet computer accounts
   • D. Distributing a printed instruction sheet that lists the required configuration steps
   Show answer

   Correct: A. MDM platforms like Intune and Jamf enroll devices and push profiles for email, passcodes, and remote wipe from one console. Manual configuration does not scale and is unenforceable. Domain GPOs apply to Windows machines joined to Active Directory, not to iOS/Android tablets. A printed sheet provides no enforcement or remote control whatsoever.

3. A user wants their corporate email, calendar, and contacts to stay synchronized across an iPhone and an Exchange server in real time. Which protocols or services support this synchronization? (Choose TWO)

   • A. Exchange ActiveSync (EAS) for pushing mail, calendar, and contacts
   • B. Microsoft 365 / Exchange Online using the native synchronization service
   • C. SMTP relay configured to forward outbound messages to the mail gateway
   • D. POP3 downloading messages to the device and removing them from the server
   • E. Telnet sessions opened directly to the mail server over TCP port 23
   Show answer

   Correct: A and B. Exchange ActiveSync and Microsoft 365 / Exchange Online both push mail, calendar, and contacts and keep them synced in real time. SMTP only sends outbound mail and never syncs calendar or contacts. POP3 typically downloads and deletes mail, breaking multi-device sync. Telnet is an insecure remote terminal protocol, not a mail synchronization service.

4. While documenting firewall rules, a technician needs the default port numbers for HTTPS, DNS, and SSH respectively. Which set of ports is correct?

   • A. 443 for HTTPS, 53 for DNS, and 22 for SSH
   • B. 80 for HTTPS, 53 for DNS, and 23 for SSH
   • C. 443 for HTTPS, 25 for DNS, and 21 for SSH
   • D. 8080 for HTTPS, 67 for DNS, and 3389 for SSH
   Show answer

   Correct: A. HTTPS uses 443, DNS uses 53, and SSH uses 22 by default. The option with 80 and 23 is wrong because 80 is plain HTTP and 23 is Telnet, not HTTPS or SSH. Port 25 is SMTP and 21 is FTP, not DNS or SSH. Ports 8080, 67, and 3389 map to alternate HTTP, DHCP, and RDP respectively.

5. A customer wants the fastest wireless standard that can use the 6 GHz band to reduce congestion in a crowded apartment building. Which Wi-Fi standard should the technician recommend?

   • A. Wi-Fi 6E (802.11ax extended into the 6 GHz band)
   • B. Wi-Fi 4 (802.11n operating only on 2.4 and 5 GHz)
   • C. Wi-Fi 5 (802.11ac operating only on the 5 GHz band)
   • D. Wi-Fi 3 (802.11g operating only on the 2.4 GHz band)
   Show answer

   Correct: A. Wi-Fi 6E extends 802.11ax into the clean 6 GHz band, ideal for congested environments. Wi-Fi 4 (802.11n) is older and limited to 2.4/5 GHz. Wi-Fi 5 (802.11ac) operates only on 5 GHz and cannot use 6 GHz. The 802.11g standard is much older and runs solely on 2.4 GHz, the most congested band.
