A technician needs to move a workstation to a different logical network segment. Which of the following technologies should the technician use?
Correct Answer:
B
Comprehensive and Detailed In-Depth Explanation:
AVLAN (Virtual LAN)is used to logically segment a network without requiring physical separation. It enables grouping devices based on function or department regardless of their physical location.
✑ Option A (DHCP):Assigns IP addresses dynamically but doesn??t create network
segments.
✑ Option C (DNS):Resolves domain names to IP addresses, not used for network segmentation.
✑ Option D (VPN):Provides secure remote access but does not relate to logical segmentation within a local network.
CompTIA A+ Core 1 Exam Objective Reference:
✑ Objective 2.3: Explain common logical networking concepts.

A technician needs to ensure all data communications on all network devices are encrypted when logging in to the console. Which of the following protocols should the technician enable?
Correct Answer:
A
SSH (Secure Shell) encrypts data communications for secure remote login and management of network devices, ensuring all console connections are encrypted.
Why Not B (LDAP): LDAP is used for directory services and does not encrypt by default. Why Not C (FTPS): FTPS encrypts file transfers, not console communications.
Why Not D (SMTP): SMTP is used for email transmission, not for securing login sessions. CompTIA A+ Exam Reference: Core 1 (220-1201), Section 2.7, network security protocols.

A user connects their laptop to a projector in a conference room. Once connected, the userreports the screen is smaller at the bottom than at the top. The user tries restarting the laptop and then disconnecting and reconnecting the cable to the projector. Which of the
following should a technician do to resolve the issue?
Correct Answer:
C
Comprehensive and Detailed Explanation From Exact Extract:
A distorted image where the screen is not symmetrical (wider at the top or bottom) is typically due to keystone distortion. Adjusting the projector's keystone settings corrects this trapezoidal effect caused by an angled projection.

A user is unable to access secure applications on their tablet when working from home a couple days per week, but the applications work when in the office. Which of the following services most likely needs to be reconfigured to allow for remote work?
Correct Answer:
B
Comprehensive and Detailed In-Depth Explanation:
Mobile Device Management (MDM)software often controls access to corporate resources based onlocation, network, or VPN status. If the MDM is not configured to allow access from outside the office or via home networks, the apps may be blocked. This is the most probable cause if apps work only on-premises.
✑ Option A:GPS is used for location services, not access control.
✑ Option C:WPA is a Wi-Fi security protocol, not related to access restrictions.
✑ Option D:NFC enables close-range communication — irrelevant to app access. CompTIA A+ Core 1 Exam Objective Reference:
✑ Objective 1.6: Given a scenario, configure basic mobile device network connectivity and application support.
