Network Policy and Access Services Microsoft Server 2008 70-642 Network Infrastructure Configuration

The ____ is the central utility for managing RADIUS clients and remote RADIUS servers, network health and access policies, NAP settings for NAP scenarios, and logging settings.

NPS console

______ protocols encapsulate data packets inside a new packet header.

Tunneling

A(n) ____ is the database used by a RADIUS server to authenticate users.

user account database

_____ provide secure network access for remote clients over the Internet through the use of tunneling protocols.

VPNs (Virtual private networks)

A(n) ____ forwards DHCPDiscover messages for subnets that do not have a DHCP server and that are not connected to a router that supports passing DHCP broadcast messages.

DHCP relay agent

____ works by encapsulating PPP frames before they are transmitted across a network.

Layer Tunneling Protocol

Routing tables can be managed in the RRAS console or from the command line using the route command. T or F

True

____ is a role service used to configure and manage network routing in Windows Server 2008.

Routing and Remote Access Services

RIPvuses ____ in determining the dynamic routes it can use for forwarding packets of data.

RIP neighbors

The ____ is a role service that provides you with a framework for creating and enforcing network access policies for client health, along with policies for authentication and authorization of connection requests. It can also be configured as a RADIUS proxy.

Network Policy Server (NPS)

As a software-based router, RRAS is recommended for use in small networks that require simple routing directions but is not recommended for large and complex environments. T or F

True

The ____ component of RRAS provides support for multicast network traffic by routing multicast traffic to networks that host these services.

IGMP router and proxy

______ allows you to shield internal IP address ranges from public networks by allowing internal clients to access the Internet through a shared IP address.

Network address translation (NAT)

____ provides Dynamic Host Configuration Protocol (DHCP) relay agent functionality for networks. This can also be done in situations where you do not have a RFC 542-compliant router.

RRAS

____ are responsible for forwarding packets between subnets, or networks with differing IP addressing schemes.

Routers

____ is the first component of the RADIUS process in which the identity of a user connecting to a resource is verified.

Authentication

____ is an industry-standard protocol that provides centralized authentication, authorization, and accounting for network access devices such as wireless access points and remote access servers.

RADIUS

____ supports securing VPNs using 28-bit RCencryption.

PPTP

A ____ is any device such as a remote access server, wireless access point, or VPN concentrator, that accepts remote connections from remote access clients. It can be an NPS, which replaces the IAS from previous versions of Windows Server.

RADIUS client

____ route traffic based on information they discover about remote networks from other routers.

Dynamic protocols

With RRAS, network adapters are added and configured to listen for UDP broadcast messages. T or F

False

Demand-dial routing allows a server to initiate a connection only when it receives data traffic bound for a remote network. Prior to the proliferation of broadband Internet connections, DUN was common for connecting remote users to their networks using a standard phone line. Both statements are ______. (True or False)

True

Sent by the RADIUS server in response to the Accounting-Request message.

Accounting-Response

Sent by a RADIUS server in response to an Access-Request message. This message informs the RADIUS client that the connection attempt is authenticated and authorized.

Access-Accept

Sent by a RADIUS client to request authentication and authorization for a network access connection attempt.

Access-Request

Sent by a RADIUS server in response to an Access-Request message.

Access-Challenge

Can be used to securely connect remote networks, such as a branch office network, to its central corporate network.

RAS

Sent by a RADIUS server in response to an Access-Request message. This message informs the RADIUS client that the connection attempt is rejected.

Access-Reject

Column on a routing table that displays the cost of using a specific route.

Metric

Sent by a RADIUS client to specify accounting information for a connection that was accepted.

Accounting-Request

A(n) ____ is a setting used to route RADIUS messages between the access client and the appropriate RADIUS server.

RADIUS proxy

A ____ is responsible for providing network access to remote access clients such as users needing VPN or dial-in network access.

network access server

____ uses PPP to encapsulate traffic for transmission across network using a secure socket layer (SSL) connection.

Secure Socket Tunneling Protocol

____ are used on networks to perform authentication, authorization, and accounting for RADIUS clients, or convey authentication requests to other centralized authenticating systems.

RADIUS servers

A UDP relay agent manages the communication between a network's DHCP server and clients on subnets without a DHCP server. T or F

False
