Riverside Towing is redesigning the network that connects its three locations. The administrator
gave the networking team 192 168.45 0 to use for addressing the entire network. After subnetting
the address, the team is ready to assign the addresses. The administrator plans to configure ip
subnet-zero and use RIP v2 as the routing protocol. As a member of the networking team, you
must address the network and at the same time conserve unused addresses for future growth.
With those goals in mind, drag the host addresses on the left to the correct router interface. One of
the routers is partially configured. Move your mouse over a router to view its configuration. Not all
of the host addresses on the left are necessary.

QUESTION NO: 17
What is the advantage of using a multipoint interface instead of point-to-point subinterfaces when
configuring a Frame Relay hub in a hub-and-spoke topology?
A. It avoids split-horizon issues with distance vector routing protocols.
B. IP addresses can be conserved if VLSM is not being used for subnetting.
C. A multipoint interface offers greater security compared to point-to-point subinterface
configurations.
D. The multiple IP network addresses required for a multipoint interface provide greater
addressing flexibility over point-to-point configurations.
Answer: B
Explanation:
Frame Relay supports two types of interfaces: point-to-point and multipoint. The one you choose
determines whether you need to use the configuration commands that ensure IP address to data-
link connection identifier (DLCI) mappings. After configuring the PVC itself, you must tell the router
which PVC to use in order to reach a specific destination.
Let's look at these options:
1. Point-to-point subinterface - With point-to-point subinterfaces, each pair of routers has
its own subnet. If you put the PVC on a point-to-point subinterface, the router assumes that there
is only one point-to-point PVC configured on the subinterface. Therefore, any IP packets with a
destination IP address in the same subnet are forwarded on this VC.
This is the simplest way to configure the mapping and is therefore the recommended method. Use
the frame-relay interface-dlci command to assign a DLCI to a specified Frame Relay subinterface.
2. Multipoint networks - Multipoint networks have three or more routers in the same subnet. If you
put the PVC in a point-to-multipoint subinterface or in the main interface (which is multipoint by
default), you need to either configure a static mapping or enable inverse Address Resolution
Protocol (ARP) for dynamic mapping.

Which two of these statements regarding RSTP are correct? (Choose two.)
A. RSTP cannot operate with PVST+.
B. RSTP defines new port roles.
C. RSTP defines no new port states.
D. RSTP is a proprietary implementation of IEEE 802.1 D STP.
E. RSTP is compatible with the original IEEE 802.1 D STP.
Answer: B,E
Explanation:
When network topology changes, rapid spanning tree protocol (IEEE802.1W, referred to as RSTP)
will speed up significantly the time to re-calculate spanning tree. RSTP not only defines the role of
other ports: alternative port and backup port, but also defines status of 3 ports: discarding status,
learning status, forwarding status.
RSTP is designed to be compatible and interoperable with the STP. However, the advantages of
the fast re-convergence, introduced by the RSTP are lost when it interoperate with STP bridges.
In order to ensure compatibility with STP bridges, each RSTP bridge listens on its ports for
configuration messages having the STP format. When a port receives such configuration message
it starts behaving as a standard 802.1d STP bridge port. Other ports continue to behave according
the RSTP.

Explanation:
Traffic that comes into the router is compared to ACL entries based on the order that the entries
occur in the router. New statements are added to the end of the list. The router continues to look
until it has a match. If no matches are found when the router reaches the end of the list, the traffic
is denied. For this reason, you should have the frequently hit entries at the top of the list. There is
an "implied deny" for traffic that is not permitted. A single-entry ACL with only one "deny" entry has
the effect of denying all traffic. You must have at least one "permit" statement in an ACL or all
traffic is blocked. In this example, since the statement will be added to the end of the access list,
and since there is already an entry that permits all IP traffic, the www traffic will be allowed, all
traffic will never reach this access list entry.

A network administrator wants to ensure that only the server can connect to port Fa0/1 on a
Catalyst switch. The server is plugged into the switch Fa0/1 port and the network administrator is
about to bring the server online. What can the administrator do to ensure that only the MAC
address of the server is allowed by switch port Fa0/1? (Choose two.)
A. Configure an access list on the switch to deny server traffic from entering any port other than
Fa0/1.
B. Configure port security on Fa0/1 to reject traffic with a source MAC address other than that of
the server.
C. Configure port Fa0/1 to accept connections only from the static IP address of the server.
D. Configure the MAC address of the server as a static entry associated with port Fa0/1.
Answer: B,D
Explanation:
You can use port security to block input to an Ethernet, Fast Ethernet, or Gigabit Ethernet port
when the MAC address of the station attempting to access the port is different from any of the
MAC addresses specified for that port.
When a secure port receives a packet, the source MAC address of the packet is compared to the
list of secure source addresses that were manually configured or autoconfigured (learned) on the
port. If a MAC address of a device attached to the port differs from the list of secure addresses,
the port either shuts down permanently (default mode), shuts down for the time you have
specified, or drops incoming packets from the insecure host. The port's behavior depends on how
you configure it to respond to a security violation.
When a security violation occurs, the Link LED for that port turns orange, and a link-down trap is
sent to the Simple Network Management Protocol (SNMP) manager. An SNMP trap is not sent if
you configure the port for restrictive violation mode. A trap is sent only if you configure the port to
shut down during a security violation.

omA. 200.1.1.64 is a default route.
B. The output shows that there are three default routes.
C. The output came from router R2.
D. The output came from a router that has four physical interfaces.
E. EIGRP is in use in this network.
Answer: E
Explanation:
In the routing table the "D" letter marks the route learned from EIGRP routing protocol. Based on
the routing table above, there are 4 directly connected IP interfaces, 2 EIGRP learned routes
(which means that EIGRP is in use on this network) and a static default route was also configured.

omA. the use of summarization for discontiguous networks
B. the use of CIDR with a routing protocol that does not support it
C. the use of VLSM with a routing protocol that does not support it
D. the use of the no auto-summary command with a protocol that does not support summarization
E. the use of the ip route 0.0.0.0 0.0.0.0 command with a routing protocol that does not support it
Answer: A
Explanation:
By default, EIGRP will automatically summarize networks at their network boundary, which can
cause problems with dis-contiguous IP networks. Since the IP routing table does indeed show a
summary route to null 0, the default behavior of EIGRP was not modified. In this network, it would
be best to disable the automatic summarization feature of EIGRP.

B. global NAT
C. dynamic NAT
D. static NAT with ACLs
E. dynamic NAT with overload
Answer: E
Explanation:
NAT overload, also called many to one NAT or Port Address Translation (PAT) allows for many IP
hosts to share a single IP address when connecting to the outside. In this case, the use of
dynamic NAT with overloading will allow for the 25 hosts to use an IP address from the NAT pool,
which will contain the 4 public IP addresses.

C. DLCI 17 describes the ISDN circuit between R2 and R3.
D. DLCI 17 is the Layer 2 address used by R2 to describe a PVC to R3.
Answer: D
Explanation:
DLCI-Data Link Connection Identifier Bits: The DLCI serves to identify the virtual connection so
that the receiving end knows which information connection a frame belongs to. Note that this DLCI
has only local significance. Frame Relay is strictly a Layer 2 protocol suite

A network administrator is trying to add a new router into an established OSPF network. The
networks attached to the new router do not appear in the routing tables of the other OSPF routers.
Given the information in the partial configuration shown below, what configuration error is causing
this problem?
Router (config)# router ospf 1
Router (config-router)# network 10.0.0.0 255.0.0.0 area 0
A. The process id is configured improperly.
B. The OSPF area is configured improperly.
C. The network wildcard mask is configured improperly.
D. The network number is configured improperly.
E. The AS is configured improperly.
F. The network subnet mask is configured improperly.
Answer: C
Explanation:
The network command specifies the IP address (10.10.10.0) followed by the wildcard mask (not
the subnet mask) and the area that is to be associated with the OSPF address range (in this case,
area 0). The wildcard mask indicates in binary how much of the IP address much be matched with
0s indicating that the bits must match and 1 indicating that they may vary. Thus 0.0.0.255 or
00000000.00000000.00000000.11111111 indicates that any bit in the last octet can vary while all
bits in the first 3 octets must match the network address (in other words, 10.10.10.xx)
Incorrect Answers:
A: This is not the problem, assuming that all 10.X.X.X networks are to be configured for OSPF.
D: Here the process ID is 99, which is valid.

Why has the network shown in the exhibit failed to converge?
A. The no auto-summary command needs to be applied to the routers.
B. The network numbers have not been properly configured on the routers.
C. The subnet masks for the network numbers have not been properly configured.
D. The autonomous system number has not been properly configured.
E. The bandwidth values have not been properly configured on the serial interfaces.
Answer: A
Explanation:
To restore the default behavior of automatic summarization of subnet routes into network-level
routes, use the auto-summary command in router configuration mode. To disable this function and
transmit subprefix routing information across classful network boundaries, use the no form of this
command. Without disabling auto summarization, each router will advertise the 192.168.20.0/24
route, and the specific /26 networks will not be known.
