0:00 Introduction
0:29 ] A technician needs to connect multiple PCs in a home office to share files and printers. Which device should be used?
1:13 C Firewall: Firewalls are used for security purposes, such as filtering and monitoring network traffic, not for connecting devices.
1:21 D Access point: Access points are used to extend the wireless network coverage, not for connecting wired devices within the same network.
1:50 Correct Answer: A Router A router is a network device that separates broadcast domains. Routers operate at Layer 3 of the OSI model and can break up
2:32 ] An administrator needs to implement access control policies for interVLAN routing. Which type of switch should be used?
3:07 A Unmanaged: Unmanaged switches do not offer the advanced features required for implementing access control policies for interVLAN routing.
3:40 ] A company is installing new PoE security cameras. Which device supplies power through the Ethernet cable?
4:37 ] A technician needs to terminate CAT6 cable runs in a server room. Which component should be used?
4:56 Correct Answer: C Patch panel A patch panel should be used to terminate CAT6 cable runs in a server room. Patch panels provide a centralized location for connecting and organizing Ethernet cables, making it easier to manage and maintain the network.
5:10 A Hub: Hubs are simple devices that connect multiple devices in a network but are not used for terminating cable runs.
5:37 ] A network technician needs to capture and analyze traffic from the local LAN. Which network appliance allows this?
6:14 A IDS: Intrusion Detection Systems (IDS) are used to monitor network traffic for malicious activity, not for capturing and analyzing all traffic.
6:47 ] Which networking device uses IGMP snooping to optimize multicast traffic?
7:52 ] Which component allows connecting wired devices to a wireless network?
8:42 C Modem: Modems are used to connect a network to the internet, not for connecting wired devices to a wireless network.
8:54 ] A company needs to implement a network access policy for BYOD clients. Which component helps enforce this?
9:30 A Switch: Switches are used to connect devices within the same network, but they do not enforce network access
10:50 C Firewall: Firewalls are used for security purposes, such as filtering and monitoring network traffic, and are not used for terminating fiber optic connections.

10:59 D Access point: Access points are used to extend the wireless network coverage and do not terminate fiber optic connections.
11:13 ] A home user needs wireless internet throughout their house. Which networking device provides this functionality?
12:08 C Router: Routers are used to connect different networks and route traffic between them. While some routers have builtin wireless access points, not all routers provide wireless functionality.
12:25 ] A company is migrating physical servers to a cloud environment. Which technology enables this?
12:47 Correct Answer: A SDN SoftwareDefined Networking (SDN) enables the migration of physical servers to a cloud environment. SDN allows for the virtualization and centralized management of network resources, making it easier to move servers and their associated applications to the cloud.
13:36 ] A technician needs to crimp CAT6 cable onto RJ45 connectors. Which tool is needed?
13:57 Correct Answer: B Punchdown tool A punchdown tool is needed to crimp CAT6 cable onto RJ45 connectors. The tool is used to insert the individual wires of the
14:12 A Loopback plug: A loopback plug is used for testing network connections and devices, not for crimping cables.
14:19 C Protocol analyzer: A protocol analyzer is used to capture and analyze network traffic, not for crimping cables.
14:27 D Cable tester: A cable tester is used to test the integrity and functionality of network cables, not for crimping cables.
14:41 ] Which device uses CSMA/CD to manage collisions?
15:25 C Switch: Switches are used to connect devices within the same network, but they do not use CSMA/CD to manage
15:33 D Firewall: Firewalls are used for security purposes, such as filtering and monitoring network traffic, not for managing
15:45 ] A network switch at a small office keeps losing power. Which standard should be implemented?
16:06 Correct Answer: B STP Spanning Tree Protocol (STP) should be implemented to prevent network issues caused by a switch losing power. STP is a network protocol that prevents loops and provides redundancy, ensuring that the network remains functional even if a switch loses power.
