1. What two advantages does CIDR provide to a network?
(Choose two.)
reduced routing table size
reduced routing update traffic
2. Refer to the exhibit. Which address is a broadcast
address for one of the subnets that are shown in the exhibit?
192.168.4.15/29
3. 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?
84
4. Which of the following are contained in the routing
updates of classless routing protocols? (Choose two.)
32-bit address
subnet mask
5. 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?
255.255.255.252
6. What does VLSM allow a network administrator to do?
utilize multiple subnet masks in the same IP address space
7. Which three interior routing protocols support VLSM?
(Choose three.)
OSPF
RIP v2
EIGRP
8. Which of the following problems does VLSM help to
alleviate?
the shortage of IP addresses
9. 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 the S0/0/0
interface on 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?
The default gateway on host B is not correctly set.
10. A network administrator is tasked with dividing up a
class C network among the QA, Sales, and Administration departments. The QA
department is made up of 10 people, the Sales is made up of 28 people, and the
Administration has 6. Which two subnets masks adequately address the QA and
Sales departments? (Choose two.)
255.255.255.224 for Sales
255.255.255.240 for QA
11. 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?
192.168.0.0/21
12 A Class C address has been assigned for use in the
network shown in the graphic. Using VLSM, which bit mask should be used to
provide for the number of host addresses required on Router A, while wasting
the fewest addresses?
/27
13. 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?
192.168.2.130/25
14. Refer to the exhibit. What subnet mask will be applied
if Router A sends a RIPv1 update for the network 172.16.1.0 to Router B?
24
15. 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?
29
16. 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?
192.1.1.224/28
17. What is a supernet?
a summarization of classful addresses
18. 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?
The subnets overlap and will be rejected by the router.
19. A router has a summary route to network 192.168.32.0/20
installed in its routing table. What range of networks are summarized by this
route?
192.168.32.0 – 192.168.47.0/24
20. 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?
CIDR
