Which of the following connections require a username, password, and SMTP server? (Select the two best answers.)
Image A. Bluetooth connection
Image B. Wi-Fi connection
Image C. POP3 connection
Image D. Exchange connection
Image E. IMAP connection
C and E. POP3 and IMAP e-mail connections require an incoming mail server (either POP3 or IMAP) and an outgoing mail server (SMTP). Bluetooth and Wi-Fi connections do not require a username or SMTP server. Bluetooth might require a PIN, and Wi-Fi will almost always require a passcode. Exchange connections require a username and password, but no SMTP server. The Exchange Server acts as the incoming and outgoing mail server.
When manually configuring a Wi-Fi connection, which step occurs after successfully entering the SSID?
Image A. Select POP3.
Image B. Check whether the device is within range of the WAP.
Image C. Enter a passcode for the network.
Image D. Scan for networks.
C. After you enter the SSID (if it’s correct) you would enter the passcode for the network. POP3 has to do with configuring an e-mail account. If you have already entered the SSID, then you should be within range of the wireless access point (WAP). Scanning for networks is the first thing you do when setting up a Wi-Fi connection.
Which of the following allows other mobile devices to wirelessly share your mobile device’s Internet connection?
Image A. NFC
Image B. Airplane mode
Image C. IMAP
Image D. Mobile hotspot
D. Mobile hotspot technology (sometimes referred to as Wi-Fi tethering) allows a mobile device to share its Internet connection with other Wi-Fi-capable devices. Another possibility would be USB tethering, but that is done in a wired fashion. NFC stands for near field communication—a technology that allows two mobile devices to send information to each other when they are in close proximity. Airplane mode will disable all wireless connectivity including (but not limited to) cellular, Wi-Fi, and Bluetooth. IMAP is another e-mail protocol similar to POP3.
Which of the following identifies the user of the device?
Image A. IMSI ID
Image B. IMEI ID
Image C. S/MIME
Image D. VPN
A. International Mobile Subscriber Identity (IMSI) or IMSI ID is used to identify the user of the device. IMEI stands for International Mobile Equipment Identity and identifies the phone used. In other words, the IMEI ID identifies the device itself. S/MIME (Secure/Multipurpose Internet Mail Extensions) is used for authentication and message integrity and is built into some e-mail clients. In other words, it is used to encrypt e-mail. Virtual private networking (VPN) technology is used to make secure connections—tunneling though the provider’s radio network.
