The number of home users and small businesses that want to use the Internet is ever increasing. The shortage of addresses is becoming a serious problem.A quick solution to this problem is called network address translation(NAT).NAT enables a user to have a large set of addresses（ ）and one address, or a smallset of addresses,externally. The traffic inside can use the large set; the traffic（ ）, the small set. To separate the addresses used inside the home or business and the ones used for the Internet, the Internet authorities have reserved three sets of addresses as（ ）addresses. Any organization can use an address out of this set without permission from the Internet authorities. Everyone knows that these reserved addresses are for private networks.They are（ ）inside the organization, but they are not unique globally. No router will（ ）a packet that has one of these addresses as the destination address.The site must have only one single connection to the global Internet through a router that runs the NAT software.A.absolutelyB.completelyC.internallyD.externallyA.localB.outsideC.middleD.aroundA.privateB.commonC.publicD.externalA.uniqueB.observableC.particularD.ordinaryA.rejectB.receiveC.denyD.forward请帮忙给出每个问题的正确答案和分析，谢谢！

Which three IP multicast related statements are true？ （Choose three.） （）A、 Multicast addresses 224.0.1.0 through 238.255.255.255 are called globally scoped addresses. They are used to multicast data between organizations and across the InternetB、 The multicast address 224.0.0.1 is a globally scoped address that has been reserved for the Network Time Protocol （NTP） by the IANAC、 Multicast addresses 239.0.0.0 through 239.255.255.255 are called limited scope addresses. They are constrained to a local group or organizationD、 Multicast addresses 224.0.0.5 and 224.0.0.6 are limited scoped addresses that have been reserved for OSPFE、 Multicast addresses 224.0.0.0 through 224.0.0.255 are used for network protocols on local LAN segments. Because they are always transmitted with a Time to Live （TTL） of 1， they are never forwarded by a router
