utilize one subnet mask transparent an autonomous system

utilize multiple subnet masks in the same IP attend to space

utilize many routing protocols in ~ an autonomous system

 

7. I beg your pardon three internal routing protocols assistance VLSM? (Choose three.)

8. I beg your pardon of the following difficulties does VLSM assist to alleviate?

the shortage that IP addresses

the difficulty of assigning static IP addresses to hosts in huge enterprises

the intricacy of implementing advanced routing protocols such together OSPF and also EIGRP

Refer to the exhibit. A network technician beginning the static path in R1 essential to reach network 10.1.1.0/24. A ping native the S0/0/0 interface on R1 to hold B fails. The technician starts testing the network and has the complying with results: 1. Pings from R1 to the S0/0/0 user interface on R2....successful 2. Pings native R1 to the Fa0/0 user interface on R2....successful 3. Pings from hold B to hosts on the 10.1.1.0/24 network....successful 4. Pings from organize B to the Fa0/0 interface on R2....successful 5. Pings indigenous R2 to host B....successful. What is the likely reason of the failure of the ping from R1 to hold B?

The default gateway on hold B is not appropriately set.

There are no routes ago to networks connected to R1 native R2.

There is a class 2 problem in between R2 and host B.

Host B has a defective Ethernet card.

(Choose two.)

255.255.255.252 for QA

• 255.255.255.224 for Sales

• 255.255.255.240 because that QA

Refer to the exhibit. A network administrator demands to develop two subnetworks from 10.0.0.0/8 for a router running RIPv2. The Admin subnet needs 120 hosts and also the Sales subnet requires 58 hosts. The network administrator assigned 10.0.1.128/25 to the Admin subnet. The Sales subnet is offered 10.0.1.192/26. What will be the result of this addressing scheme?

Because RIPv2 walk not assistance VLSM, the subnet masks will certainly not be allowed.

The subnets will certainly not have sufficient host addresses because that the provided network requirements.

The subnets overlap and will be rejected by the router.

The router will assistance the addressing scheme.
