T Q u e s t i o n 1: Correct
You are configuring NetFlow on a router. You want to monitor both incoming and outgoing
traffic on an interface.
You've used the interface command to allow you io configure the interface. What commands
should you use next? (Select two. Both responses are part of the complete solution.)
ip flow-import source < fnterface>
y ip flow ing ress
ip flow-export destination <ao'dress> <porf>
7 ip flow egress
ip flow-export source <mferface>
Explanation
Use the ip flow interface configuration command to enable NetFlow monitoring on a router
interace. Specifying ingress with this command configures NetFlow to monitor incoming
packets on the interface. Specifying egress with this command configures NetFlow to monitor
outgoing packets on the interface.
Use the ip f l o w - e x p o r t d e s t i n a t i o n <3ddness> < p o r t > command to configure the router
to export NetFlow records to the NetFlow Collector configured with the IP address and UDF
port specified. Use the ip f l o w - e x p o r t s o u r c e < i n t e r f a c e > command to specify the interface
on the router to use as the source of the packets sent to the NetFlow connector, “he ip f l o w -
i m p o r t s o u r c e < mierface> command is not a valid NetFlow command.

■ Altn BLK Root FWD Desg F'AD Desg FWD Desg FWD
C GiDQ
Root FWD
Explanation
In this example:
■ Switch B is the root bridge because :ts MAC address is the lowest. This means that GKL'1
and GiD/2 are both designated ports (Desg) and are forward ng (FWD).
- Pod Gi0i2 on switch A and GiD/2 on switch C are root ports. Root ports are forwarding.
- For the segment between switch A anc C, GiE/1 on switch C is the designated port. This is
because the MAC address for switch C is tower than the MAC add 'ess far switch A.
■ GiO.'T on switch A is an alternate port (Attn) and is blockirg (BLK). There is only one
designated port per segment, with all other ports being im a blocking slate.
Root ports are in the forwarding (FWD) state, not in backing (BLK) state.

Q u e s t i o n 3: Correct
You have decided to use ACLs on your router to restrict TFTP traffic between networks.
Specifically, you want to allow only the server with an IP address of 172. 17.3.1 to access an
TFTP server on a different network with an IP address of 10.0.3.1. The TFTP protocol runs on
□DP port 60. To accomplish this, you create the following ACL on the router connecting the
two networks:
Routerfccmf gX access-list 100
RoutericonfigX access-list 10D permit udp 172. 17.3.1 C.0.0.255 host 10.C.C-. 1 eq 65
Routericonf gX access-list 103 deny udp any any eq 65
Rcuter(configX access-list 100 permit IP any any
After applying the ACL to inbound traffic on the interface connected to the 172.1 7.8.0/24
network, you find that all hosts on the 172.17.3.0/24 network can still access the TFTP service
on 1D.D.3.1 over port 65.
Which of the following options can be used to fix this issue? (Select two.)
Ada ar aaditioral ACL line of access-list 100 deny I P any any.
Remove the ACL Ifoetbst reads a c c e s s - l i s t 100 deny udp any any eq 69.
■■ / . Modify the first ACL line t o a c c e s s - l i s t 100 permit udp 1 72.17.8.1 0.0. 0.0 host
1 0 . 0 . 0 . 1 eq 69.
J Modify the first ACL ine tc a c c e s s - l i s t 100 permit udp host 172.17.8.1 host
— 1 0 . 0 . 0 . 1 eq 69.
Modify the f rst ACL line t o a c c e s s - l i s t 100 permit udp 1 72.1 7.8.1 0.0.255.255

host 10.0.0.1 eq 69.
Explanation
This ssue is being caused by the ACL lire that reads access-list 100 p e r m i t udp
1 7 2 . 1 7 . 8 . 1 0 . 0 . 0 . 2 5 5 h o s t l O . 0.0.1 eq 69. The 0.0.0.255 mast causes this lire io be
matched by any source host whose IP adcress begins with 172.17.8, which would include sll
hosts on the 172.17.8.0/24 subnet. Ether of the following resolutions will fix this issue:
■ Mocify the first ACL line tc access-list 100 p e r m i t udp 1 7 2 . 1 7 . 8 . 1 D.0.D.0 h o s t
1 0 . 0 . 0 . 1 eq 69. This matches only the source host with an IP address of 172.17.8.1.
■ Modify the f rst ACL line to access-list 100 p e r m i t udp h o s t 172.17.8.1 h o s t 1 0.0. 0.1
eq 69. This also matches only the source host with an IP address of 172.17.8.1.
Modifying the first ACL line to access-list 1 00 permit udp 172.17.8.1 0.0.255.255 host
10. 0.0.1 eq 69 would broacen the number of matches by allowing any source host whose IP
acd ress begins with 172.17, which violates the conditions of the scenario. Removing the ACL
line that reads a c c e s s - l i s t 100 deny udp any any eq 69 would allow all TFTP t-afnc through
by any host that doesn't match the f rst line. Adding an additional ACL line of access-list 100
deny I P any any would duplicate tne effect of the implicit deny and isn't necessary.

▼ Question 4: Cor rect
Your client has acquired several small companies ard would like to connect them together into
one network Not all the routers are Cisco devices and compatibility is a concern. Which WAN
encapsulation method should you recommend ycur client use?
• PPP
Ethernet
PAP
Cisco HDLC
Explanation
The Point-to-Point (PPP} protocol is not proprietary. For this reason, it is the best choice for
connecting dissimilar vendor devices.
Cisco HDLC is the default serial encapsulation method, but is only supported on Cisco devices.
PAP ts a PPP authentication protocol. Ethernet is not a WAN protocol.

▼ Question 5: Correct
This question induces an image to help you answer the question. View Image
You have a small business network with a single subnet connected to the Internet through a
Cisco router (RouterA). IP addresses have been assigned as shown in tne Exhibit
A browser session on the workstation tries to connect to the www.westsim.com weo server

using 16.177.85.116 and port 8D.
What IF address and port number will the Web server use as the destinaton address when
responding to the workstation's request?
IF address 190.57.111.89 and port 80
IP address 172.17.1.1 and port 89
IF ad d'ess 199.67.111.89 and a dynamic port chosen by the web server
IF address 172. 17. 1.55 and port 80
• IP address 1 69.67.111.89 and a dynamic port assigned by RouterA
IF add’ess 172.17.1.55 and a port chosen by Wrk1
Explanation
When the outgoing request passes through RouterA, the router translates the private inside IP
address into a public address and a port number. The public address it uses in this case is its
own public IP address (169.57.111.89). To identify the private host, it generates a random port
number and associates that port number with the private IP address. The outgoing packet
identifies 199.67.111.89 with the random port number as the source address, so the web
server uses this address when responding to the request.

V Question 7: Incorrect
Which can be stored in NVRAM on a Cisco device? (Select two.}
] startup-config file
limited IOS version
running-config file
4 full IOS image
Explanation
The router NVRAM is flash memory that saves data when the router is powered off. NVRAM
holds the startup-config file and can also hold, depending on the device, the full IOS image.
When the router starts, it loads the IOS image into system RAM, then applies the startup-config
file to create the running-config file.
System ROM holds a limited IOS version that has minimal functionality to run the system if the
full IOS image cannot be located in NVRAM at startup.

FF02::2
FE80::1:2
FE30::2
> FF02::1:2
FE80::1
FFQ2::1
Explanation
FFQ2::1:2 is the IPv6 address used to contact a DHCP server. A l addresses with the FFDG::/8
prefix are mu t cast addresses. IPv6 uses mu toasts instead of broadcasts. FFG2::2 is the
multicast address for all route -s on the local link: FF02::1 is for all hosts on the link. FE80::/1G
is the prefix for Ink-local unicast addresses.

Explanation
Use 255.255.255.240 for the subnet mask Th s address s a Class C address. The default
subnet mask is 255.255.255.0. A subnet mask that masks an additional four bits has a binary
value of 11110DOD for the last octet. This converts to 240 decimal (128 + 04 + 32 + 16).

after being in a down state, the router multicasts a hello packet.
■ Attempt - Initially, a router's list of neighbors has a null value. As soon as it receives the
hello packet, it checks the information wthin it such as the subnet mask, area ID, and so
on.
■ I nit - If all of the information in the hello packet matches tne routers sett ng s, the muter
indicates to the neighbor that it is in the Init state. The router begins tc include the new RID

Broaccast traffic doma ns can oe def ned at Layer 2.
It eliminates the need for routing.
Explanation
The following benefits a re offered to an organ zation using network address translation (NAT):
1. NAT eliminates tne need to re-acd'ess hosts that require external netwodc access which
saves time and money.
2. With NAT, internal hosts can share a single reg stered IP add -ess for all external
communications so few external addresses are requ red io support many internal hosts thus
conserving IP adcresses.
2. The internal hosts on the private network do not advertise their addresses or internal
topcogy externally, so NAT is a type of f rewall strategy that protects network security.
NAT does not provde virtual private network (VPN) support to remote hosts, nor does it create
Layer 2 broadcast domains like a VLAN.
To implement NAT requires the use of a router.
