Which of the following statements about IPv6 anycast addresses are true? (Choose three.)
Which of the following statements about IPv6 anycast addresses are true? (Choose three.)
IPv6 anycast addresses are used to route packets to the nearest interface based on routing distance, which means packets are sent to the nearest destination (statement A). Anycast and unicast addresses do use the same address space, as anycast addresses are simply a special use of unicast addresses (statement B). IPv6 anycast addresses provide redundancy functions for services because they allow multiple devices to provide the same service and if one fails, another can take over (statement C). However, IPv6 anycast addresses do not inherently implement load balancing for services, making statement D incorrect.
La afirmación D es falsa porque las direcciones anycast de IPv6 no implementan el equilibrio de carga para los servicios.
As declarações corretas sobre endereços IPv6 anycast são: (A), (C),(D)
A, B, C: a unicast address used on more than one interface automatically becomes an anycast address. Thus, both types occupy the same address space.
correct answer is ACD
answer is ACD
A,B and C. The format of an anycast address is the same as that of a unicast address. A device, however, can send packets to multiple devices with the same anycast address. Anycast addresses have the following advantages: 1. Provide service redundancy. For example, a user can obtain the same service (for example, a web service) from multiple servers that use the same anycast address. These servers are all responders of anycast packets. If no anycast address is used and one server fails, the user needs to obtain the address of another server to establish communication again. If an anycast IPv6 Basics Page 16 address is used and one server fails, the user can automatically communicate with another server that uses the same address, implementing service redundancy.
