• Question 256:

  Company A has merged with Company B. Company A is currently using the Class A RFC1918 IP address range and OSPF as its IGP. Company B is using the Class B RFC1918 private IP address space and EIGRP as its IGP. To keep costs down, initially the two companies decided to interconnect with one another via a dedicated Ethernet link using OSPF. This link connects R1 at Company A and R2 at Company B. Clients and servers with Company A must be able to route packets to and from the clients and servers of their new colleagues in Company B.

  Which step is the most efficient way to achieve this goal?

  A. Configure OSPF on R2 and EIGRP on R1
  B. Configure iBGP between R1 and R2 and then redistribute OSPF into iBGP on R1 and redistribute EIGRP into iBGP on R2
  C. Configure mutual route redistribution between OSPF and EIGRP on R2
  D. Configure mutual route redistribution between OSPF and EIGRP on R1 and R2
  D. Configure mutual route redistribution between OSPF and EIGRP on R1 and R2

• Question 257:

  Which three statements correctly describe DSL-based Internet services for residential users? (Choose three.)

  A. Most residential deployments use PPPoE encapsulation where the end user PC or the DSL CPE will require a PPP username and password configuration.
  B. Most residential deployments use PPPoA encapsulation where the DSL CPE device needs to provide Layer 3 routing functions.
  C. The most commonly installed DSL variant for residential deployments is ADSL.
  D. The most commonly installed DSL variant for residential deployments is SDSL.
  E. The most commonly installed DSL variant for residential deployments is HDSL.
  F. At the DSL service provider location, a DSLAM typically is used to terminate all the PPP connections of the DSL subscribers.
  G. At the DSL service provider location, a DSLAM is used to terminate and then aggregate the DSL connections over an ATM network.
