Which mechanism is used to create a floating static route?
administrative distance
cost
hop count
passive interface
2
IPSec operates at which layer of the OSI model?
application
network
datalink
transport
3
Which is true regarding Frame Relay LMI?
There are three LMI types standardized by ANSI, ITU-T, and Cisco.
Routers at each end of a Frame Relay virtual circuit must always use the same LMI
type.
The LMI type must be manually configured.
The only function of LMI is to verify the connection between the router and the
Frame
Relay switch.
4
Which statement identifies the IP address design for subinterfaces that
are configured for a Frame Relay network?
Multipoint configurations require the IP address of each subinterface on each router to
be

in its own subnet.
Multipoint configurations require IP addresses for each subinterface on each router to
be
a part of the same subnet.
Point-to-point configurations require IP addresses for each subinterface on each router
to
be a part of the same subnet.
Point-to-point configurations do not require IP addresses on each subinterface on each
router.
Multipoint configurations do not require IP addresses on each subinterface on each
router.
5
Which three algorithms can be used to encrypt user data in an IPSec VPN framework?
(Choose three.)
3DES
AES
Diffie-Hellman
DES
ESP
SHA
6
Which flag is set by a Frame Relay switch to inform the receiving station that
congestion was experienced?

DE
FECN
FCS
7

Refer to the exhibit. The complete configuration of a Frame Relay interface on the
Chicago router
is shown. How does the Chicago router know which DLCI is mapped to the IP
address of the
remote router?
DE
CIR
FECN
Inverse ARP
8
What statement correctly defines the purpose of the split horizon rule?
marks the route unreachable in a routing update that is sent to other routers
prevents routers from advertising a network through the interface from which the
update came
prevents routers from accepting higher cost routes to networks previously marked as
inaccessible before the timer expires
limits the number of hops a packet can traverse through the network before it should
be discarded
9
Which PVC status suggests that the router recognizes the DLCI configured on its
interface as
being present on the Frame Relay switch, but the PVC associated with the DLCI is
not capable of
end-to-end communication?
active
deleted
inactive
idle
10
Refer to the exhibit. Which router command is used to associate a Layer 2 address

4. CCNA Discovery 4.1 - CCNA Discovery Answers
http://ccna-discovery-4.blogspot.com/
with the
corresponding Layer 3 address?
Miller(config-if)#frame-relay map ip 172.16.150.1 110
Miller(config-if)#frame-relay map ip 172.16.150.1 112
Miller(config-if)#frame-relay map ip 172.16.150.2 110
Miller(config-if)#frame-relay map ip 172.16.150.2 112
11
A network administrator issued the command show frame-relay pvc. The response
from the
router shows the status of a PVC as deleted. What is the reason for this status?
The DLCI is using the wrong LMI type.
The DLCI is usable but has little activity.
The DLCI is programmed in the switch but the circuit is not usable.
The DLCI configured on the CPE device does not match the DLCI.
12
What is one benefit of using a network simulation software package?
The network design can be tested before it is actually implemented.
Simulation software packages are quickly updated to support new network
technologies
and devices.
Simulated devices have the same features as actual devices, allowing for detection of
all
potential problems.
Software packages can simulate all possible network traffic conditions, giving an
accurate
prediction of network performance.
13
What are two components a network designer considers when planning a VPN?
(Choose two.)

5. CCNA Discovery 4.1 - CCNA Discovery Answers
http://ccna-discovery-4.blogspot.com/
encryption algorithm for privacy and security
encapsulation protocol to use when creating the VPN tunnel
switching technology to optimize VPN WAN throughput
tunneling technology for guarding against data corruption
routing protocol on the gateway for optimum performance
14
When identifying VPN requirements for endpoint users, what care must be taken to
protect the
network when remote users log in from unsecured public locations?
Ensure that the user has VPN client software that allows access to all internal
resources.
Ensure that the VPN user traffic does not slow down internally sourced traffic on the
network.
Ensure that there are no obstacles to hamper the users from accessing all internal
resources.
Ensure that remote users can only access network resources that are appropriate to
their
job function.
15
Which two components are key elements when implementing a VPN? (Choose two.)
concentration
encryption
prioritization
compression
encapsulation
16

Cisco Adaptive Security Appliances
17
What is used to identify the path to the next frame-relay switch in a Frame Relay
network?
CIR
DLCI
FECN
BECN
18
Which two statements are true regarding VPN security? (Choose two.)
Users may only establish a VPN connection from secure locations and never from
public areas.
Users that connect to a network through a VPN do not have to log in to resources on
the network.
Users that connect to a network through a VPN are are considered trusted users on the
network.
Users may establish a VPN connection from unsecure locations such as airports and
hotel lobbies.
Users that connect to a network through a VPN should have access to all the resources
on the network.
