Networking

A network administrator wants to place the accounting department and the sales department on separate broadcast domains using a single managed switch, without buying additional hardware. Which feature should be configured to accomplish this?

A company wants employees at a remote branch office to securely access resources on the main corporate LAN over the public internet as if they were locally connected. Which technology should the technician implement to meet this requirement?

A user reports that when they visit the company's internal web-based inventory portal, their browser shows a warning that the connection is 'Not Secure' and traffic could be intercepted. The technician confirms the site loads correctly but is served over an unencrypted protocol. Which change should the technician recommend so the portal uses an encrypted connection, and which default port will it then use?

A technician is setting up a small office where the existing 24-port switch is fully occupied, but six more wired workstations must be added. The technician has a second switch available. Which device is designed to interconnect the two switches and forward traffic between all the wired devices on the same local network based on MAC addresses?

A field office is being set up at a remote rural site where no cable, DSL, or fiber service is available from any local provider. The manager needs internet access for email and cloud file storage but has been warned that the chosen connection will have noticeably high latency. Which internet connection type best fits this situation?

A technician is configuring a new workstation on the corporate LAN. The device receives an IPv4 address of 169.254.18.7 and cannot reach any internal servers or the internet, but it can still communicate with a few neighboring devices on the same physical segment. Other workstations on the network are getting addresses in the 10.0.5.x range. What is the MOST likely cause?

A hospital is deploying a group of virtualization hosts that need shared, high-speed block-level access to a centralized disk array. The storage traffic must be isolated from the regular user LAN to guarantee low latency for the virtual machines' disk operations. Which type of network should the technician recommend to meet these requirements?

A technician sets a workstation's TCP/IP properties to 'Obtain an IP address automatically.' After the machine boots and successfully contacts the DHCP server, which set of configuration values does the workstation typically receive as part of a standard DHCP lease?

A technician deploys a new DHCP server in the server VLAN (10.10.1.0/24). Workstations in the accounting VLAN (10.10.5.0/24) are all receiving 169.254.x.x addresses, while devices in the server VLAN get proper leases. The router between the VLANs is functioning and can route traffic once addresses are set manually. What should the technician configure to fix the accounting VLAN?

A technician arrives at a small office where several newly powered-on workstations cannot obtain a network connection, while machines that were already running work fine. On the router's DHCP status page, the technician sees that all addresses in the configured pool are currently leased out. What is the BEST action to restore connectivity for the new workstations?

A user reports they cannot reach any websites by name in their browser, receiving 'server not found' errors. A technician has the user open a command prompt and successfully pings a public website's IP address (142.250.72.14) and receives replies. Pinging the site by its domain name fails with 'could not find host.' Which service is most likely misconfigured or unreachable?

A technician must configure a client application to upload sensitive project files to a company server. Company policy requires the file transfer session, including credentials, to be fully encrypted. Which protocol and port should the technician configure?

A small business wants visitors to have internet access from a wireless network without being able to reach the company's internal servers, printers, or workstations. All devices connect through the same managed switch and a single access point that supports multiple SSIDs. Which configuration BEST achieves this isolation?

A remote employee has a modem from their ISP that provides a single public IP address and one Ethernet port. They need to connect a desktop, a laptop, and a wireless printer to the internet at the same time, with all devices sharing that single public address. Which device should they add to accomplish this?

A technician is setting up a small business network and assigns the LAN the address range 192.168.10.0/24. During setup, a workstation displays the IP address 169.254.18.7 with a subnet mask of 255.255.0.0 and cannot reach any internal or external resources. What is the MOST likely cause?

A technician replaces a workstation's Ethernet cable and reconnects it to the switch. The link comes up, but users report extremely slow file transfers and intermittent connectivity. Checking the switch, the port shows a large number of late collisions and CRC errors, and the port is running at 100 Mbps while the NIC reports 100 Mbps full duplex. Which of the following is the MOST likely cause?

A technician manually configures a workstation with the IP address 192.168.10.50 and a subnet mask of 255.255.255.0. The user can reach other devices on the local network but cannot access the internet. The technician confirms the DNS server is reachable by other clients. Checking the configuration, the technician sees the default gateway is set to 192.168.20.1. What is the MOST likely cause of the internet connectivity failure?

A technician is deploying a shared network printer in a small office. The DHCP server hands out addresses in the range 192.168.1.100 to 192.168.1.200. The office wants the printer to always be reachable at the same address, and the technician decides to assign it a static IP manually on the printer itself. Which address should the technician assign to avoid an IP conflict while keeping the printer on the same subnet?

A company is upgrading its wireless network to reduce congestion in a dense office building where many nearby networks compete on existing channels. The IT manager wants to deploy access points that can operate on a newly available frequency band that offers wide contiguous spectrum and minimal interference from legacy devices. Which wireless standard should the manager select to take advantage of the 6 GHz band?

A technician is installing several wireless access points on the ceiling of a warehouse. There are no electrical outlets near the mounting locations, and running new AC power lines would be costly. The access points and the network switch both support IEEE 802.3af. What is the most efficient way to power the access points?
