Your organization uses a time-keeping application that only runs on Windows 2000 and does not run on newer OS versions. Because of this, there are several Windows 2000 workstations on your network. Last week, you noticed unusual activity on your network coming from the workstations. After further examination, you discover that they were victims of a malicious attack and were being used to infiltrate the network. You find out that the attackers were able to gain access to the workstations because of the legacy operating system being used. Your organization still needs to use the Windows 2000 workstations (which need to be connected to the internet) but you want to make sure that the network is protected from future attacks. Which solution should you implement to protect the network while also allowing operations to continue as normal? Create a dedicated network for the Windows 2000 workstations that's completely isolated from the rest of the network, including a separate internet connection. Configure VLAN membership so that the Windows 2000 workstations are on their own VLAN. Implement a host-based firewall on each Windows 2000 workstation, and configure them to automatically download and install updates. Install antivirus software on the Windows 2000 workstations, and configure them to automatically download and install updates.

Configure VLAN membership so that the Windows 2000 workstations are on their own VLAN.

You manage your company's website, which uses a cluster of two servers with a single shared storage device. The shared storage device uses a RAID 1 configuration. Each server has a single connection to the shared storage and a single connection to your ISP. You want to provide redundancy so that a failure on a single component doesn't cause the website to become unavailable. What should you add to your configuration to accomplish this? Connect one server to the internet through a different ISP. Reconfigure the disk array in a RAID 1+0 configuration. On each server, add a second network connection to connect the server to the shared storage device. On each server, add a second network connection to the internet.

You are an application developer. You use a hypervisor with multiple virtual machines installed to test your applications on various operating system versions and editions. Currently, all of your test virtual machines are connected to the production network through the hypervisor's network interface. You are concerned that the latest application you are working on could adversely impact other network hosts if errors exist in the code. To prevent problems, you decide to isolate the virtual machines from the production network. However, they still need to be able to communicate directly with each other. What should you do? (Select two. Each response is one part of the complete solution.) Disconnect the network cable from the hypervisor's network interface. Create a new virtual switch configured for host-only (internal) networking. Disable the switch port that the hypervisor's network interface is connected to. Create MAC address filters on the network switch that block each virtual machine's virtual network interfaces. Connect the virtual network interfaces in the virtual machines to the virtual switch. Create a new virtual switch configured for bridged (external) networking.

You are adding a new rack to your data center, which will house two new blade servers and a new switch. The new servers will be used for virtualization. The only space you have available in the data center is on the opposite side of the room from your existing rack, which already houses several servers, a switch, and a router. You plan to configure a trunk port on each switch and connect them with a straight-through UTP cable that will run across the floor of the data center. To protect equipment from power failures, you also plan to install a UPS on the rack along with redundant power supplies for the server. Will this configuration work? Yes, this configuration complies with data center best practices. No, you should not use blade servers for virtualization. No, you must implement the UPS and power supplies on the rack externally. No, you should not run a cable across the data center floor. No, you must use a cross-over cable to connect the two switches together.

You are adding a new rack to your data center, which will house two new blade servers and a new switch. The new servers will be used for file storage and a database server. The only space you have available in the data center is on the opposite side of the room from your existing rack, which already houses several servers, a switch, and a router. You plan to configure a trunk port on each switch and connect them with a crossover UTP plenum cable that will run through the suspended tile ceiling in the data center. To provide power for the new devices, you had an electrician install several new 20-amp wall outlets near the new rack. Each device on the rack will be plugged directly into one of these new wall outlets. What is wrong with this configuration? (Select two.) You should not run a plenum cable through a suspended tile ceiling. You should not connect networking equipment to a 20-amp wall circuit. You should implement a UPS between the wall outlet and the network devices. You must use a straight-through cable to connect the two switches together. You should implement redundant power supplies for the network devices.
