Where are DHCP database backups stored by default?
DHCP Failover
Which high-availability option for DHCP should you configure if you want a DHCP server to operate in hot standby mode without having to configure shared storage?
Maximum client lead time
Which of the following defines the maximum amount of time that a DHCP server can extend a lease for a DHCP client without the partner server's knowledge?

Which option is NOT configured when you create a DHCPv6 scope?
Stateless autoconfiguration
Which type of IPv6 configuration uses router advertisements for prefix assignment?
Exclusion range
You have created a new DHCP scope with address range 192.168.1.1 to 192.168.1.254. You have five servers configured with static addresses in the range 192.168.1.240 to 192.168.1.244. You plan on configuring as many as ten more servers to use static addresses in the range 192.168.1.245 to 192.168.1.254. What should you configure on your scope?
Superscope
You have expanded your current LAN from about 200 hosts to over 350 hosts. The first 200 hosts were getting IP addresses from a scope configured with the address range 10.1.1.1 to 10.1.1.250 with prefix length 24. You don't want to change the IP addressing scheme for the existing hosts, but you need to accommodate all 350 hosts with DHCP-assigned addresses. You don't have any VLANs or routers configured. What should you configure?
Multicast Scope
You have installed a streaming video service on your network. You want selected hosts to be able to access this service via a dynamically assigned class D IP address. What do you need to configure?
February 11 at 8:00AM
You have just installed a DHCP server and created a new scope with the default options. A DHCP client leases an IP address at 8:00am on Monday, February 3rd. When will the client lease expire if it is never renewed?
Relay agent on Network 2
You have two LANs connected via a router. Network 1 has a DHCP server with a single Ethernet interface. Network 2 does not have a DHCP server. You want the hosts on Network 2 to be able to get IP addresses from the DHCP server on Network 1. What should you configure?
68
A DHCP server sends information back to a client on what UDP port?
5
A DHCPINFORM request sent by a client will receive what message number from a DHCP server as an acknowledgment?
Mac Address
An IP address reservation is made by creating an association between an IP address and what type of client identifier?
When the lease is 50% expired
At what point does a client send a unicast packet to the DHCP server to request a lease renewal for its current IP address?
The server no longer listens to UDP port 67 on the disabled binding
Disabling an interface's binding on a DHCP server has what impact?
By using the name protection option
How can a DHCP server be configured to not register A and PTR records if a DNS record with a different name already exists?
By using the Reconcile All Scopes option
How can an administrator attempt to automatically fix inconsistencies between DHCP summary lease information kept in the Registry and detailed lease information stored in the DHCP database?
The server sends a DHCPNACK
How does a DHCP server respond to an IP request that can not be renewed?
87.5% OF LEASE INTERVAL EXPIRED
If a DHCP server does not respond to a client's first renewal request, how long will the client keep its current address until initiating the next lease renewal request?
Reservation Options
The DHCP options defined at what level take precedence over all other levels?
Option 60
The Vendor Class uses what option field within a DHCPDISCOVER packet?
Configure Reservations
You just got a shipment of 10 network-attached laser printers. You want these printers to always have the same address but you want the addresses to be assigned via DHCP. What should you do?
Split scope
You want to configure two DHCP servers; one is running Windows Server 2012 R2, and the other is running Windows Server 2016. One will be the primary server, and the other should assign addresses to clients only if the primary server doesn't respond within about a second. You don't want replication to be part of the configuration. What should you configure?
