42
Q

Your manager wants you to determine which computer has obtained the IP address 172.16.16.75. How could you find out using the IPAM console?

A

You could open the IPAM console and select the By IP Address node in the Event Catalog. In the Search box, type the address 172.16.16.75, and click Search. The returned results should indicate which client computer has leased that address.

43
Q

You want to enable DHCP high-availability by using the IPAM console. What DHCP
high-availability option(s) can you configure with the console?

A

You can enable and configure DHCP failover by using the IPAM console.

44
Q

What does the Set Access Scope option do when applied to a DHCP scope?

A

The Set Access Scope option enables you to define the management scope for a
DHCP or DNS object. This determines who can manage the object.

45
Q

The network at A. Datum consists of multiple subnets. You do not want to deploy a
DHCP server into each physical subnet, but want to ensure that all client computers
can obtain an IP configuration via a DHCP server. What could you do to facilitate this?

A

If your routers support BOOTP forwarding, as defined by RFC 1542, you need do noth-
ing more as the DHCP messages are forwarded between subnets by the routers. How-
ever, if your routers do not support this function, you can deploy DHCP Relay Agents
on Windows Server 2016 computer by using the Routing and Remote Access console.

46
Q

You want to deploy the DHCP server role without using the Server Manager console.
How could you achieve this?

A

You can use the Add-WindowsFeature DHCP –IncludeManagementTools Windows
PowerShell command to install the DHCP server role and required management tools.

47
Q

You want to create a scope for an IPv4 subnet with the address
172.16.16.0/255.255.240.0. How many subnet bits must you configure when you create
the scope?

A

A subnet mask of 255.255.240.0 means 20 bits must be assigned when you create the
scope.

48
Q

You want to use a non-Microsoft software deployment package to deploy applications
to client computers. The application uses multicast IP. How could DHCP help with this
scenario?

A

DHCP supports the use of Multicast scopes to support applications and clients that use
multicast communications.

49
Q

You want to be able to assign a shorter lease duration to users of Windows tablets.
How could you achieve this?

A 
You can create a scope in DHCP, and then define a user class for tablet devices. Assign
the tablets to the user class with the IPconfig.exe tool. Finally, create a DHCP scope-
level policy to assign a different lease duration for devices that match the condition of
user class = laptop.
50
Q

Your manager asks you to look into providing DHCP resilience for a branch office.
Currently, the network clients obtain an IPv4 configuration from a DHCP server located
in the regional HQ in London. Whenever there is a network failure, the clients at the
branch are unable to obtain an IPv4 configuration. What possible solutions are avail-
able to mitigate this issue, and which would you recommend to your manager?

A

There are a number of possible solutions. One solution would be to manually assign
IPv4 addresses to all clients in the branch. This would negate the need for DHCP, but it
does make management of the organization’s IP address space more complicated. Us-ing DHCP, possible solutions include placing a DHCP server at the branch and config-
uring it with the required scope for that branch. This is probably the simplest solution,
and requires no failover configuration. If you preferred to allocate IPv4 addresses from
the London offices, then using split scope would work well, with the Delay in DHCP
Offer value set higher on the branch DHCP server so that it does not offer addresses
unless the London DHCP server is unresponsive. You would need to take care to set
this value correctly because obtaining an IP configuration over a wide area network
link is slower than over a local area network link.

51
Q

There was an incident recently when a DHCP server failed, and users in London were
unable to obtain an IP configuration on their laptop computers. Your manager wants
you to ensure that this never happens again. What could you do?

A

This scenario is probably best resolved by using DHCP failover. Configure a DHCP
scope(s) for the London offices on one DHCP server, and then implement DHCP
failover in load sharing mode, distributing the scope 50/50. This optimizes perfor-
mance and helps to ensure high availability.

52
Q

Client computers in one part of the London site are failing to obtain an IP configura-
tion. These computers are located in a separate building across the road from the
main London HQ offices. You investigate the building and discover that it has no DHCP
server locally. What would you do next to start to resolve the problem?

A

Since client computers are unable to obtain an IP configuration from servers located in
the main office, it is the link to the main office that should be investigated. Determine
whether any routers are offline. Verify that if a DHCP relay agent is used, it is online
and configured correctly. Finally, verify that the DHCP server the clients normally use is
online. Also, check that the scope from which they obtain their configurations is active.

53
Q

Your manager wants you to determine which computer has obtained the IP address
172.16.16.75. How could you find out using the IPAM console?

A

You could open the IPAM console and select the By IP Address node in the Event Cata-
log. In the Search box, type the address 172.16.16.75, and click Search. The returned
results should indicate which client computer has leased that address.

54
Q

You have deployed your first IPAM server and performed GPO-based provisioning. You
ran the Invoke-IpamGpoProvisioning cmdlet to complete the provision process. What
comes next?

A

After provisioning, you must configure and complete the server discovery process.

55
Q

You want to enable DHCP high-availability by using the IPAM console. What DHCP
high-availability option(s) can you configure with the console?

A

You can enable and configure DHCP failover by using the IPAM console.

56
Q

What does the Set Access Scope option do when applied to a DHCP scope?

A

The Set Access Scope option enables you to define the management scope for a
DHCP or DNS object. This determines who can manage the object.
