200-301 Question #685: Real Exam Question with Answer & Explanation

Question

Lab Simulation 3 Guidelines This is a lab item in which tasks will be performed on virtual devices. - Refer to the Tasks tab to view the tasks for this lab item. - Refer to the Topology tab to access the device console(s) and perform the tasks. - Console access is available for all required devices by clicking the device icon or using the tab(s) above the console window. - All necessary preconfigurations have been applied. - Do not change the enable password or hostname for any device. - Save your configurations to NVRAM before moving to the next item. - Click Next at the bottom of the screen to submit this lab and move to the next question. - When Next is clicked, the lab closes and cannot be reopened. Topology Tasks Configure IPv4 and IPv6 connectivity between two routers. For IPv4, use a /28 network from the 192.168.180.0/24 private range. For IPv6, use the first /64 subnet from the 2001:0db8:acca::/48 subnet. 1. Using Ethernet0/1 on routers R1 and R2, configure the next usable /28 from the 192.168.180.0/24 range. The network 192.168.180.0/28 is unavailable. 2. For the IPv4 /28 subnet, router R1 must be configured with the first usable host address. 3. For the IPv4 /28 subnet, router R2 must be configured with the last usable host address. 4. For the IPv6 /64 subnet, configure the routers with the IP addressing provided from the topology. 5. A ping must work between the routers on the IPv4 and IPv6 address ranges.

Options

• taskConfigure IPv4 and IPv6 connectivity between two routers (R1 and R2). For IPv4, use a /28 network from the 192.168.180.0/24 private range (excluding 192.168.180.0/28). For IPv6, use the first /64 subnet from the 2001:db8:acca::/48 subnet.
• prerequisitesConsole access is available for all required devices (R1 and R2) by clicking the device icon or using the tab(s) above the console window. All necessary preconfigurations have been applied.
