This exam have 83 points 1 Which statement is true about
wildcard masks? A wildcard mask must be created by inverting the
subnet mask. A wildcard mask performs the same function as a subnet
mask. A wildcard mask of 0.0.0.0 means the address should match
exactly. A wildcard mask uses a "1" to identify IP address bits
that must be checked. 2
Refer to the exhibit. EIGRP has been configured as a routing
protocol on the network. Users on the 192.168.1.0/24 network should
be able to establish a TFTP connection to the file server on the
192.168.3.0/24 network for file backup. The users complain that
they do not have the required access. What is the possible cause of
the problem? TFTP uses UDP as a transport protocol. UDP is not
allowed by the ACL 120. TFTP uses SMTP as a transport protocol.
SMTP is blocked by statement 10 in the ACL 120. TFTP uses TCP as a
transport protocol. TCP is blocked by statement 20 in the ACL
120.
TFTP uses ICMP as a transport protocol. ICMP is blocked by
statement 30 in the ACL 120. 3 Which three guidelines would help
contribute to creating a strong password policy? (Choose three.)
Once a good password is created, do not change it. Deliberately
misspell words when creating passwords. Create passwords that are
at least 8 characters in length. Use combinations of upper case,
lower case, and special characters. Write passwords in locations
that can be easily retrieved to avoid being locked out. Use long
words found in the dictionary to make passwords that are easy to
remember. An administrator is configuring a dual stack router with
IPv6 and IPv4 using RIPng. The administrator receives an error
message when trying to enter the IPv4 routes into RIPng. What is
the cause of the problem? When IPv4 and IPv6 are configured on the
same interface, all IPv4 addresses are over-written in favor of the
newer technology. Incorrect IPv4 addresses are entered on the
router interfaces. RIPng is incompatible with dual-stack
technology. IPv4 is incompatible with RIPng. Which two protocols in
combination should be used to establish a link with secure
authentication between a Cisco and a non-Cisco router? (Choose
two.) HDLC PPP SLIP PAP CHAP What functionality do access control
lists provide when implementing dynamic NAT on a Cisco router?

which addresses are to be translated 7 Which statement is true
of DSL? It is typically deployed in a mesh topology. The network is
shared using a logical bus topology. Bandwidth is dependent on the
number of concurrent users. Transfer rates are dependent on the
length of the local loop. At what physical location does the
responsibilty for a WAN connection change from the user to the
service provider? demilitarized zone (DMZ) demarcation point local
loop cloud

Refer to the exhibit. Based on the output as shown, which two
statements correctly define how the router will treat Telnet
traffic that comes into interface FastEthernet 0/1? (Choose two).
Telnet to 172.16.10.0/24 is denied.
Telnet to 172.16.20.0/24 is denied. Telnet to 172.16.0.0/24 is
permitted. Telnet to 172.16.10.0/24 is permitted. Telnet to
172.16.20.0/24 is permitted. 10
Refer to the exhibit. Which data transmission technology is
being represented? TDM PPP HDLC SLIP 11 What are two main
components of data confidentiality? (Choose two.) checksum digital
certificates encapsulation encryption
hashing 12 Which characteristic of VPN technology prevents the
contents of data communications from being read by unauthorized
parties? QoS latency reliability confidentiality 13 When
configuring a Frame Relay connection, what is the purpose of
Inverse ARP? to assign a DLCI to a remote peer to disable peer
requests from determining local Layer 3 addresses to negotiate LMI
encapsulations between local and remote Frame Relay peers to create
a mapping of DLCI to Layer 3 addresses that belong to remote peers
14 What are three attributes of a security policy? (Choose three.)
It provides step-by-step procedures to harden routers and other
network devices. It defines acceptable and unacceptable use of
network resources. It focuses primarily on attacks from outside of
the organization. It defines a process for managing security
violations. It should not need to be altered once implemented. It
creates a basis for legal action if necessary. 15
Refer to the exhibit. Branch A has a non-Cisco router that is
using IETF encapsulation and Branch B has a Cisco router. After the
commands that are shown are entered, R1 and R2 fail to establish
the PVC. The R2 LMI is Cisco, and the R1 LMI is ANSI. The LMI is
successfully established at both locations. Why is the PVC failing?
The PVC to R1 must be point-to-point. LMI types must match on each
end of a PVC. The frame relay PVCs cannot be established between
Cisco and non-Cisco routers. The IETF parameter is missing from the
frame-relay map ip 10.10.10.1 201 command.
16 A network administrator has moved the company intranet web
server from a switch port to a dedicated router interface. How can
the administrator determine how this change has affected
performance and availability on the company intranet? Conduct a
performance test and compare with the baseline that was established
previously.
Determine performance on the intranet by monitoring load times
of company web pages from remote sites. Interview departmental
administrative assistants and determine if they think load time for
web pages has improved. Compare the hit counts on the company web
server for the current week to the values that were recorded in
previous weeks. 17 What will be the result of the enable secret
command when added at the global configuration mode on the router?
It will use MD5 encryption to protect the privileged EXEC level
access. It will use type 7 encryption and will encrypt only the
privileged EXEC level passwords. It will use type 7 encryption to
prevent all passwords that are displayed on the screen from being
readable. It will use MD5 encryption to protect the passwords that
are only used in the PAP and CHAP authentication process. 18 Which
Layer 2 access method separates traffic into time slots and is
specified by DOCSIS for use with cable high speed Internet service?
TDMA FDMA CDMA S-CDMA 19 What major benefit does Cisco HDLC provide
that ISO standard HDLC lacks? flow control error control
multiprotocol support cyclic redundancy checks 20
Refer to the exhibit. R1 is performing NAT overload for the
10.1.1.0/24 inside network. Host A has sent a packet to the web
server. What is the destination IP address of the return packet
from the web server? 10.1.1.2:1234 172.30.20.1:1234
172.30.20.1:3333 192.168.1.2:80 21 Which section of a security
policy is used to specify that only authorized individuals should
have access to enterprise data? statement of scope statement of
authority Internet access policy acceptable use policy campus
access policy identification and authentication policy 22
Refer to the exhibit. What happens if the network administrator
issues the commands shown when an ACL called Managers already
exists on the router? The commands overwrite the existing Managers
ACL. The commands are added at the end of the existing Managers
ACL. The network administrator receives an error stating that the
ACL already exists. The commands will create a duplicate Managers
ACL containing only the new commands being entered. 23
Refer to the exhibit. Partial results of the show ip access-list
and show ip interface Fa0/1 commands for router
R3 are shown. There are no other ACLs in effect. Host A is
unable to telnet to host B. Which two actions will correct the
problem but still restrict other traffic between the two networks?
(Choose two.) Apply the ACL in the inbound direction on Fa0/0
interface. Apply the ACL in the outbound direction on Fa0/0
interface. Change the protocol in the access list entries to UDP.
Reverse the order of the TCP protocol statements in the ACL. Modify
the second entry in the list to permit tcp host 192.168.10.10 any
eq telnet . 24 During the initial configuration of a router, the
administrator enters the command no service config. How will the
router behave as a a result of this command? All services will be
disabled. The default configuration will be restored on reboot.
Automatic configuration from the network will be prevented.
Services that are configured on the router will not be allowed to
originate traffic. 25
Refer to the exhibit. A host connected to Fa0/0 is unable to
acquire an IP address from the DHCP server. The output of the debug
ip dhcp server command shows "DHCPD: there is no address pool for
192.168.3.17". What is the problem?
The address 192.168.3.17 address is already in use by Fa0/0. The
pool of addresses for the 192Network pool is configured
incorrectly. The ip helper-address command should be used on the
Fa0/0 interface. The 192.168.3.17 address has not been excluded
from the 192Network pool. 26 An administrator issues the command
confreg 0x2142 at the rommon 1> prompt. What is the effect when
this router is rebooted? Contents in RAM will be erased. Contents
in RAM will be ignored. Contents in NVRAM will be erased. Contents
in NVRAM will be ignored. 27 An administrator learns of an e-mail
that has been received by a number of users in the company. This
e-mail appears to come from the office of the administrator. The
e-mail asks the users to confirm their account and password
information. Which type of security threat does this e-mail
represent? cracking phishing phreaking spamming 28 A technician
wants to configure a host with an IPv6 site-local address. Which
address should be used? FE80::/10 FEC0::/10 2000::/3 FF00::/8 29 A
recently patched application server is experiencing response time
problems. The network on which the application server is located
has been experiencing occasional outages that the network team
believes may be related to recent routing changes. Network and
application teams have been notified to work on their respective
issues. Which statement applies to this situation? Only results
from the software package should be tested as the network is
designed to accommodate the
proposed software platform. Scheduling will be easy if the
network and software teams work independently. It will be difficult
to isolate the problem if two teams are implementing changes
independently. Results from changes will be easier to reconcile and
document if each team works in isolation. 30
Refer to the exhibit. Router1 is not able to communicate with
its peer that is connected to this interface. Based on the output
as shown, what is the most likely cause? interface reset unplugged
cable improper LMI type PPP negotiation failure
31

Refer to the exhibit. The corporate network that is shown has
been assigned network 172.16.128.0/19 for use at branch office
LANs. VLSM is not being used. Which subnet mask will allow the most
efficient utilization of IP addresses? /21 /22 /23 /24 /25 /26
37
Refer to the exhibit. A network administrator is tasked with
completing the Frame Relay topology that interconnects two remote
sites. How should the point-to-point subinterfaces be configured on
HQ to complete the topology? frame-relay interface-dlci 103 on
Serial 0/0/0.1 frame-relay interface-dlci 203 on Serial 0/0/0.2
frame-relay interface-dlci 301 on Serial 0/0/0.1 frame-relay

broadcast on Serial 0/0/0.2 38 Which statement accurately describes
a role that is played in establishing a WAN connection?
ISDN and ATM are circuit-switched technologies that are used to
establish on demand a path through the service provider network.
Data link layer protocols like PPP and HDLC define how data is
encapsulated for transmission across a WAN link. A packet-switching
network establishes a dedicated circuit between nodes for the
duration of the communication session. Frame Relay switches are
normally considered to be customer premises equipment (CPE) and are
maintained by local administrators. 39
Refer to the exhibit. Which statement correctly describes how
Router1 processes an FTP request packet that enters interface
S0/0/0, and is destined for an FTP server at IP address 172.16.1.5?
The router matches the incoming packet to the statement that is
created by access-list 201 permit ip any any command and allows the
packet into the router. The router reaches the end of ACL 101
without matching a condition and drops the packet because there is
no statement that was created by access-list 101 permit ip any any
command.
The router matches the incoming packet to the statement that was
created by the access-list 101 permit ip any 172.16.1.0 0.0.0.255
command, ignores the remaining statements in ACL 101, and allows
the packet into the router. The router matches the incoming packet
to the statement that was created by the access-list 201 deny icmp
172.16.1.0 0.0.0.255 any command, continues comparing the packet to
the remaining statements in ACL 201 to ensure that no subsequent
statements allow FTP, and then the router drops the packet. 40 A
network administrator is tasked with maintaining two remote
locations in the same city. Both locations use the same service
provider and have the same service plan for DSL service. When
comparing download rates, it is noticed that the location on the
East side of town has a faster download rate than the location on
the West side of town. How can this be explained? The West side has
a high volume of POTS traffic. The West side of town is downloading
larger packets. The service provider is closer to the location on
the East side. More clients share a connection to the DSLAM on the
West side. 41 A light manufacturing company wishes to replace its
DSL service with a non-line-of-sight broadband wireless solution
that offers comparable speeds. Which solution should the customer
choose? Wi-Fi satellite WiMAX Metro Ethernet 42
Refer to the exhibit. From the output of the show interfaces and
ping commands, at which layer of the OSI model is a fault
indicated? application transport network data link physical 43
Refer to the exhibit. A network administrator is trying to
configure a router to use SDM. After this configuration shown in
the exhibit is applied, the SDM interface of the router is still
not accessible. What is the cause of the problem? The username and
password are not configured correctly. The authentication method is
not configured correctly. The HTTP timeout policy is not configured
correctly. The vtys are not configured correctly. 44 What is a
characteristic feature of a worm? exploits a known vulnerability
attaches to executable programs masquerades as a legitmate program
lies dormant until triggered by an event, time, or date 45
Refer to the exhibit. EIGRP has been configured as a routing
protocol on the network. Users on the 192.168.1.0/24 network should
have full access to the web server that is connected to
192.168.3.0/24 but should not be allowed to telnet to router R3.
Verifying the configuration, the network administrator realizes
that users on network 192.168.1.0/24 can successfully telnet to the
router. What should be done to remedy the problem? The ACL 101
statements 10 and 20 should be reversed. The ACL 101 should be
applied on R3 VTY lines 0 4 in the inbound direction. The ACL 101
should be applied on R3 VTY lines 0 4 in the outbound direction.
The ACL 101 should be applied on R3 Serial0/0/1 interface in the
outbound direction. The ACL 101 statement 10 should be changed to:
permit ip 192.168.1.0 0.0.0.255 any 46
Refer to the exhibit. A network administrator is creating a
prototype to verify the new WAN design. However, the communication
between the two routers cannot be established. Based on the output
of the commands, what can be done to solve the problem? Replace the
serial cable . Replace the WIC on RA. Configure RA with a clock
rate command. Issue a no shutdown interface command on RB. 47 What
is the result when the command permit tcp 10.25.132.0 0.0.0.255 any
eq smtp is added to a named access control list and applied on the
inbound interface of a router? TCP traffic with a destination to
the 10.25.132.0/24 is permitted. Only Telnet traffic is permitted
to the 10.24.132.0/24 network Ttraffic from 10.25.132.0/24 is
permitted to anywhere on using any port. Traffic using port 25 from
the 10.25.132.0/24 is permitted to all destinations.
48
Refer to the exhibit. This serial interface is not functioning
correctly. Based on the output shown, what is the most likely
cause? improper LMI type interface reset PPP negotiation failure
unplugged cable 49 A technician has been asked to run the Cisco SDM
one-step lockdown on a customer router. What will be the result of
this process? Traffic is only accepted from and forwarded to
SDM-trusted Cisco routers. Security testing is performed and the
results are saved as a text file stored in NVRAM. All traffic that
enters the router is quarantined and checked for viruses before
being forwarded. The router is tested for any potential security
problems and all recommended security-related configuration changes
will be automatically applied. 50
Refer to the exhibit. All devices are configured as shown in the
exhibit. PC1 is unable to ping the default gateway. What is the
cause of the problem? The default gateway is in the wrong subnet.
STP has blocked the port that PC1 is connected to. Port Fa0/2 on S2
is assigned to the wrong VLAN. S2 has the wrong IP address assigned
to the VLAN30 interface. 51 Which statement is true about NCP? Link
termination is the responsibility of NCP. Each network protocol has
a corresponding NCP. NCP establishes the initial link between PPP
devices. NCP tests the link to ensure that the link quality is
sufficient. 52 What can a network administrator do to recover from
a lost router password?
use the copy tftp: flash: command boot the router to bootROM
mode and enter the b command to load the IOS manually telnet from
another router and issue the show running-config command to view
the password boot the router to ROM monitor mode and configure the
router to ignore the startup configuration when it initializes
