QuestionQ14

Implement and manage an on-premises and hybrid networking infrastructure

DRAG DROP -

Your network contains an Active Directory Domain Services (AD DS) domain.

The domain contains three servers named DHCP1, DHCP2, and DHCP3 that run Windows Server and have the DHCP Server role installed. The servers host IPv4 scopes only. Shared storage is unavailable.

Your company has a main datacenter that contains DHCP1 and DHCP2. The company has a disaster-recovery datacenter that contains DHCP3 and connects to the main datacenter by using a WAN link.

You have two scopes named Scope1 and Scope2.

You need to provide DHCP service continuity for the scopes. The solution must meet the following requirements:

Scope1: DHCP3 must provide leases only if a DHCP server in the a main datacenter is unavailable.

Scope2: DHCP1 and DHCP2 must each lease from separate parts of the IP address range. DHCP2 must wait before responding to client computer requests.

How should you configure high availability for each scope? To answer, drag the appropriate configurations to the correct scopes. Each configuration may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.

NOTE: Each correct selection is worth one point.

Explanation

DHCP failover in hot standby mode establishes an active server and a standby partner for a scope; the standby server issues leases only if the active server stops responding, which is exactly the behavior needed for a disaster-recovery server that must remain silent while a main-datacenter DHCP server is reachable. A split scope divides one address range into separate, independently managed portions hosted on two different DHCP servers with no shared storage or state replication required, and configuring it with delayed responses makes the secondary server wait a short interval before answering client broadcast requests, so the primary server's replies are used whenever it is available while the delayed server only responds if the primary does not - matching the requirement that two main-datacenter servers each lease from a separate part of the range while one server (DHCP2) waits before responding.
