Why does it matter how close to the home fiber comes?

With copper cable, bandwidth drops precipitously with distance. The most recent expedient, vectored DSL, allows 50 Mbps downstream signals for as far as 1,800 feet under ideal conditions. It won’t work on very old copper wiring, its upstream bandwidth is limited and it requires expensive electronics. However, it is touted as an interim solution for network builders that cannot afford FTTH. In the next few years, a new technology, G.fast, will become available; under ideal conditions and with vectoring (crosstalk cancellation), G.fast is expected to provide 500 Mbps symmetrical bandwidth up to 300 feet from the node. G.fast may prove to be an excellent solution for retrofitting apartment buildings with fiber to the basement (as long as those buildings have good internal wiring), but it requires bringing fiber very close to customer premises and is still limited in comparison with true fiber to the home.

QUESTION 1 You have a server named Server1 that runs Windows Server 2016. You install the Hyper-V server role on Server1. Server1 has eight network adapters that are az-100 dedicated to virtual machines. The network adapters are Remote Direct Memory Access (RDMA)-enabled. You plan to use Software Defined Networking (SDN). You will host the virtual machines for multiple tenants on the Hyper-V host. You need to ensure that the network connections for az-101 the virtual machines are resilient if one or more physical network adapters fail. What should you implement? A. single root I/O virtualization (SR-IOV) B. NIC Teaming on the Hyper-V host C. virtual Receive-side Scaling (vRSS) D. Switch Embedded Teaming (SET) Correct Answer: D QUESTION 2 You have servers named Server1 and DHCP1. az-102 Both servers run Windows Server 2016. DHCP1 contains an IPv4 scope named Scope1. You have 1,000 client computers. You need to configure Server1 to lease IP addresses for Scope1. The solution must ensure that Server1 is used to respond to up to 30 percent of the DHCP client requests only. You install the DHCP Server server role on Server1. What should you do next? A. From the DHCP console, run the Configure Failover wizard. B. From Server Manager, install the Network Load Balancing feature. C. From Server Manager, install the Failover Clustering feature. D. From the DHCP console, create a superscope. Correct Answer: A microsoft.com QUESTION 3 Note: This question is part of a series of az-300 questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. You have a server named Server1 that has the Network Policy and Access Services server role installed. You create a Shared Secret Network Policy Server (NPS) template named Template1. You need to view the shared secret string used for Template1. Solution: From the Network Policy Server console, you az-301 export the templates, and you view the exported XML file. Does this meet the goal? A. Yes B. No Correct Answer: B QUESTION 4 You have a server named Server1 that runs Windows Server 2016. You install the DHCP Server server role on Server1. You need to authorize DHCP on Server1. What should you run? A. dism.exe B. dns.exe C. dnscmd.exe D. netsh.exe E. Set-DhcpServerDatabase F. Set-DhcpServerv4DnsSetting G. Set-DhcpServerv6DnsSetting H. Set-DNSServerSetting Correct Answer: D QUESTION 5 Note: This question is part of a series az-302 of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution. After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen. Your network contains an Active Directory domain named az-900 adatum.com. The domain contains two DHCP servers named Server1 and Server2. Server1 has the following IP configuration. Server2 has the following IP configuration. Some users report that sometimes they cannot access the network because of conflicting IP addresses. You need to configure DHCP to avoid leasing addresses that are in use already. Solution: On Server1, you modify the EndRange IP address of the scope. Does this meet the goal? A. Yes B. No Correct Answer: A QUESTION 6 Your network contains an Active Directory domain named ms-900 contoso.com that contains a domain controller named DC1. All DNS servers for the network run BIND 10. Your perimeter network contains a DHCP server named DHCP1 that runs Windows Server 2016. DHCP1 is a member of a workgroup named WORKGROUP. DHCP1 provides IP address leases to guests accessing the Wi-Fi network. Several engineers access the network remotely by using a VPN connection to a remote access server that runs Windows Server 2016. All of the VPN connections use certificate-based authentication and are subject to access policies in Network Policy Server (NPS). Certificates are issued md-100 by an enterprise certification authority (CA) named CA1. All Windows computers on the network are activated by using Key Management Service (KMS). On-premises users use Remote Desktop Services (RDS). You plan to deploy IP Address Management (IPAM) to the network. Which action can you perform on the network by using IPAM? A. Audit user and device logon event from NPS. B. Audit logon events on the RDS server. C. Audit configuration changes to the remote access server. D. Audit certificate enrollment requests on CA1. Correct Answer: A microsoft.com QUESTION 7 Your network contains an Active Directory domain named contoso.com. The domain contains a DNS server named Server1. Server1 is configured to use a forwarder named Server2 that has an IP address of 10.0.0.10. Server2 can resolve names hosted on the Internet successfully. Server2 hosts a primary DNS zone named adatum.com. On Server1, you have the following zone configuration. The “.” zone contains the following records. For each of the following statements, select Yes if ms-100 the statement is true. Otherwise, select No. Hot Area: Correct Answer: QUESTION 8 You have a Scale-Out File Server that has a share named Share1. Share1 contains a virtual disk file named Disk1.vhd. You plan to create a guest failover cluster. You need to ensure that you can use the virtual disk as a shared virtual disk for the gust failover cluster. Which cmdlet should you use? A. Optimize VHD B. Optimize VHDSet C. Convert-VHD D. Set-VHD Correct Answer: C QUESTION 9 You have a server named Server1 that runs Windows dp-200 Server 2016. Server1 is located on the perimeter network, and only inbound TCP port 443 is allowed to connect Server1 from the Internet. You install the Remote Access server role on Server1. You need to configure Server1 to accept VPN connections over port 443. Which VPN protocol should you use? A. PPTP B. SSTP C. L2TP D. IKEv2 Correct Answer: B microsoft.com QUESTION 10 Your network contains multiple wireless access points (WAPs) that use WPA2-Personal authentication. The network contains an enterprise root certification authority (CA). The security administrator at your company plans to implement WPA2-Enterprise authentication on the WAPs. To support the authentication change, you deploy a ms-500 server that has Network Policy Server (NPS) installed. You need to configure NPS to authenticate the wireless clients. What should you do on the NPS server? A. Add RADIUS clients and configure network policies. B. Create a remote RADIUS server group and configure connection request policies. C. Create a remote RADIUS server group and install a server certificate. D. Add RADIUS clients and configure ms-101 connection request policies.
