Question 2mediummultiple choice
Full question →A workstation is connected to a managed switch. It obtains a valid IP address (192.168.10.50) from the DHCP server, but it cannot ping the default gateway (192.168.10.1). The link light on both the workstation NIC and the switch port are solid green. Other workstations on the same switch CAN ping the default gateway successfully. The technician accesses the switch management interface and finds that the workstation's port is configured as an access port on VLAN 10. The default gateway is located on VLAN 20. An inter-VLAN router is configured but not explicitly allowing VLAN 10 access to VLAN 20. Which of the following is the MOST likely cause of the problem?
Question 3mediummultiple choice
Full question →A company has a router with four Ethernet ports. They need to connect 12 wired devices in the same LAN segment. All devices must receive IP addresses from the same DHCP server running on the router. Which device should the technician add?
Question 4hardmultiple choice
Full question →A company hosts multiple VMs on a Type 1 hypervisor. The physical host has two NICs configured in a teamed pair for redundancy and load balancing. The administrator creates a new VM and attaches it to a virtual switch that is bound to the NIC team. The VM can communicate with other VMs on the same host but cannot communicate with any devices on the physical LAN. Other VMs on the same host can reach the physical LAN. Which of the following is the most likely cause?
Question 5mediummultiple choice
Full question →A company uses a cloud platform where users can provision virtual servers and storage through a web portal without any human interaction with the IT staff. This capability is an example of which cloud computing characteristic?
Question 6mediummultiple choice
Full question →A company replaces an unmanaged network switch with a new managed switch in a small office. After reconnecting all devices, some workstations can access the internet, but others cannot. The workstations that cannot access the internet are all connected to ports 1-8 of the new switch, while workstations on ports 9-16 work normally. The router is connected to port 24. The technician checks the switch configuration and finds that all ports are in the default VLAN 1, but ports 1-8 have been accidentally reassigned to VLAN 2. Which of the following is the MOST likely reason the workstations on ports 1-8 cannot access the internet?
Question 7mediummultiple choice
Full question →A company uses a managed PoE switch to power IP phones. A new IP phone is connected to a wall jack that is patched to the switch. The switch port shows 'not powered' in the management interface, even though PoE is enabled globally and the phone is known to work. Which of the following is the MOST likely cause?
Question 8mediummultiple choice
Full question →A network administrator is setting up a new wireless network for a small business. The administrator configures a wireless access point with WPA2-PSK and a strong passphrase. Several users on different floors report intermittent connectivity and slow speeds. The administrator checks the access point and finds that the signal strength is excellent in the area. The access point is dual-band (2.4GHz and 5GHz) and broadcasts a single SSID. Which of the following is the MOST likely cause of the issue?
Question 9hardmultiple choice
Full question →A network administrator configures a router with VLANs. Devices on VLAN 10 can successfully ping a web server (IP 192.168.20.10) on VLAN 20. However, when users on VLAN 10 attempt to access the web server via a browser using its IP address, the connection times out. The router's ACLs permit ICMP and TCP/80 traffic between VLANs. Which of the following should the administrator check NEXT?
Question 10hardmultiple choice
Full question →A network administrator configures a new managed switch with 24 ports. All ports are in the same VLAN (VLAN 1) by default. The administrator then changes ports 1-12 to VLAN 10 and ports 13-24 to VLAN 20. Computers connected to ports in different VLANs are assigned IP addresses from the same DHCP server. Which of the following is a direct consequence of this configuration?
Question 11hardmultiple choice
Full question →A network administrator is setting up a wired network for a small office that has 25 workstations, 2 file servers, and a router with 4 LAN ports. The office uses IP-based printers and VoIP phones. The administrator wants to minimize broadcast traffic and improve network performance by separating the workstations from the servers and printers. Which of the following is the BEST solution?
Question 12mediummultiple choice
Full question →A network technician connects two switches together using a straight-through Cat6 Ethernet cable. Both switches are managed and are known to be working. After connecting, the link LED on Switch A is off, and the link LED on Switch B is also off. The technician has verified that both switch ports are enabled and not administratively shut down. Which of the following is the MOST likely cause of the problem?
Question 13easymultiple choice
Full question →A network technician changes the company's subnet mask from 255.255.255.0 to 255.255.0.0 to accommodate network growth. All workstations use DHCP except one file server that has a static IP address of 192.168.1.50 with subnet mask 255.255.255.0 and default gateway 192.168.1.1. After the change, a user reports that they cannot access the file server. The user's workstation obtains its IP via DHCP and can access the internet. Which of the following is the most likely cause of the issue?
Question 14mediummultiple choice
Full question →A network technician is configuring a managed switch for a small office. The security policy requires that only specific authorized devices should be allowed to connect to the network via the switch ports. The technician wants the switch to automatically learn the MAC addresses of the first device that connects to each port and then lock that port to only that MAC address. Any other device connecting to the same port should be blocked. Which switch feature should be configured to accomplish this?
Question 15mediummultiple choice
Full question →A network technician is setting up a small office with 15 workstations. The ISP provides a single public IPv4 address. The technician configures the router to assign private IP addresses (192.168.1.x) to the workstations via DHCP. Which technology allows all 15 workstations to share the single public IP address to access the internet?
Question 16mediummultiple choice
Full question →A network technician is configuring a managed switch for a small office. The security requirement is that only specific authorized devices should be allowed to connect to the network via the switch ports. The technician wants to automatically learn the MAC addresses of devices as they connect and lock them to the port to prevent unauthorized devices from using the same port. Which switch feature should be configured to accomplish this?
Question 17hardmultiple choice
Full question →A network technician is tasked with providing secure remote access for employees who work from home. The solution must encrypt all traffic between the remote devices and the corporate network and must allow the remote devices to access internal resources (e.g., file servers, intranet) as if they were directly connected to the office LAN. Which of the following technologies should the technician implement?
Question 18mediummultiple choice
Full question →A network technician is configuring a small office network with one router and one managed switch. The network has two VLANs: VLAN 10 (Sales) and VLAN 20 (Engineering). Both VLANs need internet access, and inter-VLAN routing is not required. The technician configures the router's single physical interface with IP 192.168.1.1/24 and creates subinterfaces for VLAN 10 (192.168.10.1/24) and VLAN 20 (192.168.20.1/24). The switch port connecting to the router is configured as an access port in VLAN 10. Which of the following is the MOST likely result?
Question 19mediummultiple choice
Full question →A small business has a 24-port PoE+ switch powering 12 IP cameras (each requiring 15W) and 8 VoIP phones (each requiring 6W). The switch has a PoE budget of 240W. A technician installs two additional IP cameras (each 15W) but they do not power on. The existing cameras and phones continue to work normally. The technician has verified the Ethernet cables are good and the ports are enabled. Which of the following is the MOST likely cause?
Question 20easymultiple choice
Full question →A network technician is connecting two network switches in a small office to extend the wired network. The technician uses two cables between the switches for redundancy, but the network becomes unstable and devices experience intermittent connectivity. Which of the following protocols should the technician implement to prevent network loops while allowing the redundant links?
