1 / 17

What can a DHCP server set aside using reservations or exclusions?

IP addresses for specific network functions

Temporary IP addresses for devices checking in with the server

Specific devices to receive the same IP address every time

2 / 17

What type of IP addresses does DHCP assign based on MAC address?

"Halfway through" ones for renewal

Dynamic, temporary ones

"Rebind" ones if primary server is unavailable

Static, permanent ones

3 / 17

What does the DHCP server use to assign an IP address to a device?

Randomly generated IP address

IP address based on device hostname

Available address from a pool

Static IP address

4 / 17

What do address leases show in a DHCP server?

Previously assigned IP addresses

Reserved and excluded IP addresses from the range

Pools of IP addresses for assignment

Temporary and permanent IP addresses based on MAC address

5 / 17

When does the device attempt to renew its IP address during the DHCP lease process?

After the T2 timer has completed 50% of the lease time

After the T2 timer has expired

After the T1 timer has completed 50% of the lease time

At the beginning of the lease period

6 / 17

When does the rebinding period occur in the DHCP lease process?

After the T1 timer has expired

At the beginning of the lease period

After the T2 timer has expired

After the T2 timer has completed 50% of the lease time

7 / 17

How do home or small office DHCP servers differ from others?

They are embedded on routers with different configuration values

They specify the scope and pools of IP addresses for assignment

They allow devices to rebind with another DHCP server if the primary one is unavailable

They allocate static, permanent IP addresses based on MAC address

8 / 17

What is the purpose of scope options in a DHCP server?

To exclude IP addresses from the DHCP range

To ensure a specific device gets the same IP address

To specify the scope and pools of IP addresses

To allocate IP addresses for specific network functions

9 / 17

Which setting determines how long a workstation can hold on to the same IP address?

Subnet mask

Default gateway

DNS server settings

Lease duration

10 / 17

What is the purpose of IP reservations in a DHCP server?

To ensure a specific device gets the same IP address

To specify the scope and pools of IP addresses

To allocate IP addresses for specific network functions

To exclude IP addresses from the DHCP range

11 / 17

What is one of the configuration settings needed inside the DHCP server?

Hostname range

MAC address range

IP address range

Domain name range

12 / 17

What does a Windows Server device specify for assignment by a DHCP server?

The halfway point for a device to renew the lease

The timeframe devices keep an IP address before checking in with the DHCP server

The duration before a device can rebind with another DHCP server

The ability to renew or rebind based on server availability

13 / 17

What triggers the restart of the timer during the DHCP lease process?

Unavailability of original DHCP server

Completion of 50% of the lease time

Renewal of IP address with a redundant DHCP server

Expiry of both T1 and T2 timers

14 / 17

Which function does the T1 timer serve in a DHCP server?

Checks in with the DHCP server halfway through the lease time to renew the lease

Assigns dynamic, temporary IP addresses or static, permanent ones based on MAC address

Allows a device to rebind with another DHCP server if the primary one is unavailable

Determines how long a device keeps an IP address before checking in with the DHCP server

15 / 17

What happens if the original DHCP server is no longer available during the second lease process?

The device reverts to a static IP address

The device renews its IP address with the same DHCP server

The lease time is extended automatically

The device attempts to contact a redundant DHCP server

16 / 17

What is usually a very large contiguous range of IP addresses used for DHCP?

/8 subnet pool

/32 subnet pool

/16 subnet pool

/24 subnet pool

17 / 17

In what circumstance does the T2 timer come into play?

When a device keeps an IP address before checking in with the DHCP server

When devices need to rebind with another DHCP server if the primary one is unavailable

When devices need to rebind with another DHCP server after attempting to renew

When devices need to renew their lease halfway through the duration
