01. What two advantages does CIDR provide to a network? (Choose two.)
Refer to the exhibit. The network administrator wants to create a
subnet for the point-to-point connection between the two routers. Which
subnetwork mask would provide enough addresses for the point-to-point
link with the least number of wasted addresses?
Refer to the exhibit. A network engineer is summarizing the two groups
of routes on router R1 shown in the exhibit. Which summarization will
work for all the subnets?
Refer to the exhibit. What subnet mask will
be applied by router B when it receives a RIPv1 update for the network 172.16.1.0?
Refer to the exhibit. The network administrator wants to minimize the
number of entries in Router1’s routing table. What should the
administrator implement on the network?
What range of networks are summarized by this route?
In the network shown in the graphic, three bits were borrowed from the
host portion of a Class C address. How many valid host addresses will be
unused on the three point-to-point links combined if VLSM is not used?
An additional subnet is required for a new Ethernet link between
Router1 and Router2 as shown in the diagram. Which of the following
subnet addresses can be configured in this network to provide a maximum
of 14 useable addresses for this link while wasting the fewest
addresses?
Refer to the exhibit. The number of required host addresses for each
subnet in a network is listed in the exhibit. This number includes the
host address requirements for all router ports and hosts on that subnet.
After all device and router port address assignments are determined,
what will be the total number of unused host addresses available?
Refer to the exhibit. In the network that is
shown, the router interfaces are assigned the first address in each subnet. Which IP address would be usable for a host on one of the LANs in this network?
Refer to the exhibit. Which address is a broadcast address for one of the subnets that are shown in the exhibit?
Refer to the exhibit. A network administrator needs to create two
subnetworks from 10.0.0.0/8 for a router running RIPv2. The Admin subnet
requires 120 hosts and the Sales subnet requires 58 hosts. The network
administrator assigned 10.0.1.128/25 to the Admin subnet. The Sales
subnet is given 10.0.1.192/26. What will be the result of this
addressing scheme?
Refer to the exhibit. A network technician enters the static route in
R1 needed to reach network 10.1.1.0/24. A ping from R1 to Host B fails.
The technician begins testing the network and has the following results:
1. pings from R1 to the S0/0/0 interface on R2....successful
2. pings from R1 to the Fa0/0 interface on R2....successful
3. pings from Host B to hosts on the 10.1.1.0/24 network....successful
4. pings from Host B to the Fa0/0 interface on R2....successful
5. pings from R2 to Host B....successful
What is the likely cause of the failure of the ping from R1 to Host B?

administrator assigned 10.0.1.128/25 to the Admin subnet. The Sales
subnet is given 10.0.1.192/26. What will be the result of this
addressing scheme?- Because RIPv2 does not support VLSM, the subnet masks will not be allowed.
- The subnets will not have enough host addresses for the given network requirements.
- The subnets overlap and will be rejected by the router.
- The router will support the addressing scheme.
Refer to the exhibit. A network technician enters the static route in
R1 needed to reach network 10.1.1.0/24. A ping from R1 to Host B fails.
