Question 1

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.

Accepted Answer

The Network Policy Server (NPS) is a role service in Windows Server that provides a platform for creating and enforcing network access policies for client health, along with policies for authentication and authorization of connection requests. The other options, IGMP router and DHCP relay agent, are services related to multicasting and IP address assignment, respectively. The network access server is a generic term for a device or software component that provides remote access to a network.

Question 2

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.

Accepted Answer

RRAS is a basic routing tool that is suitable for small and simple networks but may not be able to handle the routing needs of large and complicated ones.

Question 3

____ supports securing VPNs using 128-bit RC4 encryption.

Accepted Answer

PPTP (Point-to-Point Tunneling Protocol) supports securing VPNs using 128-bit RC4 encryption. NAT (Network Address Translation) and NIC (Network Interface Card) are not related to VPN encryption. RADIUS (Remote Authentication Dial-In User Service) is an authentication protocol used for remote access, but it is not directly related to VPN encryption.

Question 4

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

Accepted Answer

The Routing and Remote Access Services role is used to configure and manage network routing in Windows Server 2008. DHCP is used for assigning IP addresses, IGMP is used for multicasting, and RADIUS is used for authentication and authorization.

Question 5

____ 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.

Accepted Answer

RADIUS (Remote Authentication Dial-In User Service) is a protocol that allows centralized management of user authentication, authorization, and accounting for network access devices such as wireless access points and remote access servers. It is an industry-standard protocol widely used in enterprise networks. DHCP (Dynamic Host Configuration Protocol) is used for automatically assigning IP addresses to network devices, UDP (User Datagram Protocol) and TCP/IP (Transmission Control Protocol/Internet Protocol) are protocols used for data transmission over networks but do not provide authentication or authorization services.

Question 6

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

Accepted Answer

RRAS (Routing and Remote Access Service) is a feature in Windows Server that provides routing, NAT, and VPN services. It does not add network adapters or configure them to listen for UDP broadcast messages.

Question 7

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.

Accepted Answer

The NPS console (Network Policy Server) 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. UDP (User Datagram Protocol) is a communication protocol used for transmitting data over the internet, while a supplicant is a client device that requests access to a network. VPN (Virtual Private Network) is a technology used to create a secure and encrypted connection between two or more devices over the internet. None of these options would be the central utility for managing the mentioned settings and policies like the NPS console.

Question 8

____ provides Dynamic Host Configuration Protocol (DHCP) relay agent functionality for networks.

Accepted Answer

RRAS (Routing and Remote Access Service) provides DHCP relay agent functionality for networks by forwarding DHCP messages between DHCP clients and DHCP servers on different subnets.

Question 9

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

Accepted Answer

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

Question 10

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

Accepted Answer

Layer 2 Tunneling Protocol (L2TP) works by encapsulating PPP frames before they are transmitted across a network. This allows for secure communication between two points on a network, and can be used to provide remote access or to connect two networks together.

Question 11

RIPv2 uses ____ in determining the dynamic routes it can use for forwarding packets of data.

Accepted Answer

RIPv2 uses information from its RIP neighbors to determine the dynamic routes it can use for forwarding packets of data. It exchanges routing information with its directly connected neighbors and uses distance-vector algorithms based on hop count to determine the best path to a network. There is no mention of root hints, SIDs, or RADIUS clients being used in this process.

Question 12

____ are composed of routes.

Accepted Answer

Routing tables are composed of routes that specify how network traffic should be directed. Relay agents are used in DHCP to forward messages between DHCP clients and servers. Supplicants are devices that request access to a network through a RADIUS server. RADIUS servers are used for remote authentication and authorization.

Question 13

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

Accepted Answer

The Secure Socket Tunneling Protocol (SSTP) uses PPP to encapsulate traffic for transmission across a network using a secure socket layer (SSL) connection. SSTP is primarily used for remote access VPN connections and is built into Windows Server and some Windows client operating systems. Dial-up networking and TCP/IP are not relevant to this question, and a header is a component of a network packet, but not an appropriate answer choice for this question.

Question 14

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

Accepted Answer

Routers are specifically designed to forward packets between subnets. They can connect networks with different IP addressing schemes by using routing tables to determine the best path for forwarding packets from one network to another. VPNs are used to create a secure network connection over a public network, but they do not specifically deal with forwarding packets between subnets. Databases and DHCP relay agents also do not have the specific function of forwarding packets between subnets.

Question 15

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.

Accepted Answer

A DHCP relay agent forwards DHCPDiscover messages to a DHCP server on behalf of clients on subnets that do not have a DHCP server or are not connected to a router that supports passing DHCP broadcast messages. The DHCP relay agent listens for DHCP broadcast messages and unicasts them to the DHCP server, along with its own IP address.

Question 16

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

Accepted Answer

IGMP (Internet Group Management Protocol) router and proxy is the component of RRAS that provides support for multicast network traffic by routing multicast traffic to networks that host these services. IGMP is used by hosts to inform their local multicast router about the multicast groups they want to receive. The router then uses this information to forward multicast traffic to the specific hosts that have subscribed to the multicast group.

Question 17

In situations where you do not have a RFC 1542-compliant router, you can create a DHCP relay agent using ____.

Accepted Answer

RRAS (Routing and Remote Access Service) can act as a DHCP relay agent, forwarding DHCP requests and responses between DHCP clients and servers on different subnets. It is a convenient solution in situations where a RFC 1542-compliant router is not available. XML, UDP, and TCP/IP are not suitable for creating a DHCP relay agent.

Question 18

A RADIUS client can be an NPS, which replaces the IAS from previous versions of Windows Server.

Accepted Answer

NPS (Network Policy Server) replaced the IAS (Internet Authentication Service) as the RADIUS server in Windows Server 2008. So, NPS can be used as a RADIUS client in Windows Server.

Question 19

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

Accepted Answer

Dynamic protocols, such as OSPF and BGP, are responsible for exchanging information about remote networks with other routers and using that information to dynamically route traffic. Authentication servers verify the identity of clients, supplicants are clients requesting access to a network, and stub zones are a type of DNS zone.

Question 20

A UDP relay agent manages the communication between a network's DHCP server and clients on subnets without a DHCP server.

Accepted Answer

The answer of A UDP relay agent manages the communication...
