NEW QUESTION 57
A data center provider has designed a network using these requirements:
* Two data center sites are connected to the public Internet.
* Both data centers are connected to different Internet providers.
* Both data centers are also directly connected with a private connection for the internal traffic, and public Internet traffic can also be routed at this direct connection.
* The data center provider has only one /19 public IP address block.
Under normal conditions, Internet traffic should be routed directly to the data center where the services are located. When one Internet connection fails, the complete traffic for both data centers should be routed by using the remaining Internet connection. In which two ways can this routing be achieved? (Choose two.)
- A. The data center provider must have an additional public IP address block for this routing.
- B. BGP will always load-balance the traffic to both data center sites.
- C. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out without path prepending and the /20 block from the remote data center is sent out with path prepending at both sites.
- D. One /20 block is used for the first data center and the second /20 block is used for the second data center. Each /20 block is only sent out locally. The /19 block is sent out at both
Internet connections for the backup case to reroute the traffic through the remaining
Internet connection. - E. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP weight and the /20 block from the remote data center is sent out with a higher BGP weight at both sites.
- F. One /20 block is used for the first data center and the second /20 block is used for the second data center. The /20 block from the local data center is sent out with a low BGP local preference and the /20 block from the remote data center is sent out with a higher
BGP local preference at both sites.
