You need to configure Network Policy Server (NPS) to forward authentication requests to fabrikam.com.
What should you configure on the NPS server?

A.    connection request policies
B.    system health validators (SHVs)
C.    health policies
D.    remediation server groups

Answer: A
Explanation:
Connection request policies are sets of conditions and settings that allow network administrators to designate which Remote Authentication Dial-In User Service (RADIUS) servers perform the authentication and authorization of connection requests that the server running Network Policy Server (NPS) receives from RADIUS clients. Connection request policies can be configured to designate which RADIUS servers are used for RADIUS accounting.

QUESTION 333
Your network contains an Active Directory domain named contoso.com.
The domain contains a server named Server3 that has the DHCP Server server role installed.
You need to configure Windows Firewall on Server3 to allow IPv4 client computers access to the DHCP Server service.
Which port or ports should you allow through Windows Firewall?

A.    TCP 53 and UDP 53
B.    TCP 995
C.    TCP 67 and TCP 68
D.    UDP 995
E.    TCP 993
F.    TCP 587 and UDP 587
G.    UDP 993
H.    UDP 546 and UDP 547
I.    TCP 1433
J.    UDP 67 and UDP 68
K.    TCP 546 and TCP 547
L.    TCP 636
M.    UDP 1433

Answer: J
Explanation:
Use of well-known UDP ports for client/server communication
Both BOOTP and DHCP use the same reserved protocol ports for sending and receiving messages between servers and clients. Both BOOTP and DHCP servers use UDP port 67 to listen for and receive client request messages. BOOTP and DHCP clients typically reserve UDP port 68 for accepting message replies from either a BOOTP server or DHCP server.
Because DHCP and BOOTP messages use nearly identical format types and packet structures, and typically use the same well-known service ports, BOOTP or DHCP relay agent programs usually treat BOOTP and DHCP messages as essentially the same message type, without differentiating between them.

QUESTION 334
Your network contains an Active Directory domain named contoso.com.
The domain contains a server named Server2 that has the DNS Server server role installed.

C.    TCP 993
D.    TCP 995
E.    UDP 995
F.    TCP 67 and TCP 68
G.    TCP 636
H.    TCP 587 and UDP 587
I.    TCP 546 and TCP 547
J.    UDP 67 and UDP 68
K.    UDP 1433
L.    TCP 1433
M.    TCP 53 and UDP 53

Answer: M
Explanation:
In general, all DNS queries are sent from a high-numbered source port (above 1023) to destination port 53, and responses are sent from source port 53 to a high-numbered destination port. The following table lists the UDP and TCP ports used for different DNS message types
