Networks can be interconnected by different devices. In the physical layer, networks can be connected by(66)or hubs, which just move the bits from one network to an identical network. One layer up we find bridges and switches, which operate at data link layer. They can accept(67), examine the MAC address, and forward the frames to a different network while doing minor protocol translation in the process. In the network layer, we have routers that can connect two networks. If two networks have(68)network layer, the router may be able to translate between the packet formats. In the transport layer we fmd transport gateway, which can interface between two transport connections. Finally, in the application layer, application gateways translate message(69). As an example, gateways between Internet e-mail and X.400 e-mail must(70)the e-mail message and change various header fields.A．repeatersB．relaysC．connectorsD．modems

Refer to the exhibit. A Boston company bought th e assets of a New York company and is trying to route traffic between the two data networks using EIGRP. The show command output shows that traffic will not flow between the networks. As a network consultant, you were asked to modify the configuration a nd certify the interoperability of the two networks. For traffic to flow from subnet 172.16.8.0/24 to the 172.16.16.0/24 subnet, which configuration change do you recommend?（）A. Turn off autosummarization on routers N1 and B1.B. Add IP summary addre sses to the Internet - pointing interfaces of routers N1 and B1.C. Turn off autosummarization on routers N2 and B2.D. Add wildcard masks to the network commands on routers N2 and B2.
● Networks can be interconnected by different devices. In the physical layer，networks can be connected by（1）or hubs，which just move the bits from one network to an identical network. One layer up we find bridges and switches，which operate at data link layer. They can accept（2）,examine the MAC address，and forward the frames to a different network while doing minor protocol translation in the process. In the network layer，we have routers that can connect two networks. If two networks have（3）network layer， the router may be able to translate between the packet formats. In the transport layer we find transport gateway， which can interface between two transport connections.

IPsec, also known as the internet Protocol ( ) , defines the architecture for security services for IP network traffic IPsec describes the framework for providing security a the IP layer, as well as the suite of protocols designed to provide that security: through_ ( )_ and encryption of IP network packets. IPec can be used 10 protect network data, for example, by setting up circuits using IPsec ( ), in which all data being sent between two endpoints is encrypted, as with a Virtual (请作答此空) Network connection ;for encrypting application layer data ;and for providing security for routers sending routing data across the public internet. Internet traffic can also be secured from host to host without the use of IPsec, for example by encryption at the ( ) layer with HTTP Secure (TTPS)or an the transport layer wit the Transport Layer Security (TLS)protocol.A.pubic]B.private]C.personalD.proper
A virtual (71) network, or VPN, is an encrypted connection over the Internet from a device to a network. The encrypted connection helps ensure that sensitive data is safely (72). It prevents (73) people fromeavesdropping on the traffic and allows the user to conduct work remotely. Traffic on the virtual network is sent securely by establishing an encrypted connection across the Internet known as a (74).A remote access VPN securely connects a device outside the corporate office. A site-to-site VPN connects the corporate office to branch offices over the Internet. Site-to-site VPNs are used when distance makes it impractical to have direct network connections between these offices. Think of site-to-site access as (75) to network.
