300-115 exam dumps pdf
Mary is sending an instant message to Robert. The message will be broken into a series of
packets that will traverse all network devices. What addresses will populate these packets
as they are forwarded from Router1 to Router2?
300-115 exam dumps pdf
A. Option A
B. Option B
C. Option C
D. Option D
E. Option E
Answer: B
Explanation:
The Source and Destination IP address is not going to change. Host 1 IP address will stay as being the source IP and the Host 2 IP address will stay the destination IP address. Those two are not going to change. For the MAC address it is going to change each time it goes from one hope to another. (Except switches… they don’t change anything) Frame leaving HOST 1 is going to have a source MAC of Host 1 and a destination MAC of Router 1.
Router 1 is going to strip that info off and then will make the source MAC address of
Router1’s exiting interface, and making Router2’s interface as the destination MAC address.
Then the same will happen… Router2 is going to change the source/destination info to the source MAC being the Router2 interface that it is going out, and the destination will be Host2’s MAC address.

300-115 Exam Dumps PDF Question No : 2 – (Topic 1) A workstation has just resolved a browser URL to the IP address of a server. What protocol
will the workstation now use to determine the destination MAC address to be placed into
frames directed toward the server?
A. HTTP
B. DNS
C. DHCP
D. RARP
E. ARP
Answer: E
Explanation:
The RARP protocol is used to translate hardware interface addresses to protocol addresses. The RARP message format is very similar to the ARP format. When the booting computer sends the broadcast ARP request, it places its own hardware address in both the sending and receiving fields in the encapsulated ARP data packet. The RARP server will fill in the correct sending and receiving IP addresses in its response to the message. This way the booting computer will know its IP address when it gets the message from the RARP server

300-115 Exam Dumps PDF Question No : 3 – (Topic 1) Which protocol uses a connection-oriented service to deliver files between end systems?
A. TFTP
B. DNS
C. FTP
D. SNMP
E. RIP

Answer: C
Explanation:
TCP is an example of a connection-oriented protocol. It requires a logical connection to be established between the two processes before data is exchanged. The connection must be maintained during the entire time that communication is taking place, then released afterwards. The process is much like a telephone call, where a virtual circuit is established- the caller must know the person’s telephone number and the phone must be answered– before the message can be delivered. TCP/IP is also a connection-oriented transport with orderly release. With orderly release, any data remaining in the buffer is sent before the connection is terminated. The release is accomplished in a three-way handshake between client and server processes. The
connection-oriented protocols in the OSI protocol suite, on the other hand, do not support orderly release. Applications perform any handshake necessary for ensuring orderly release. Examples of services that use connection-oriented transport services are telnet, rlogin, and ftp.

300-115 Exam Dumps PDF Question No : 4 – (Topic 1) Refer to the exhibit.
If the hubs in the graphic were replaced by switches, what would be virtually eliminated?
A. broadcast domains
B. repeater domains
C. Ethernet collisions
D. signal amplification
E. Ethernet broadcasts
Answer: C
Explanation:
Modern wired networks use a network switch to eliminate collisions. By connecting each
device directly to a port on the switch, either each port on a switch becomes its own
collision domain (in the case of half duplex links) or the possibility of collisions is eliminated
entirely in the case of full duplex links.

300-115 exam dumps pdf
Host A is sending a packet to Host B for the first time. What destination MAC address will
Host A use in the ARP request?
A. 192.168.0.1
B. 172.16.0.50
C. 00-17-94-61-18-b0
D. 00-19-d3-2d-c3-b2
E. ff-ff-ff-ff-ff-ff
F. 255.255.255.255
Answer: E
Explanation:
For the initial communication, Host A will send a broadcast ARP (all F’s) to determine the
correct address to use to reach the destination.
ARP sends an Ethernet frame called an ARP request to every host on the shared link-layer
legmen. The Ethernet header includes the source host MAC address and a destination
address of all Fs representing a broadcast frame. The ARP request contains the sender’s
MAC and IP address and the target (destination) IP address. The target’s MAC address is
set to all 0s.

300-115 exam dumps pdf
What kind of cable should be used to make each connection that is identified by the
numbers shown?
A. 1 – Ethernet Crossover cable
2 – Ethernet straight-through cable
3 – Fiber Optic cable
4 – Rollover cable
B. 1 – Ethernet straight-through cable
2 – Ethernet straight-through cable
3 – Serial cable
4 – Rollover cable
C. 1 – Ethernet rollover cable
2 – Ethernet crossover cable
3 – Serial cable
4 – Null-modem cable
D. 1 – Ethernet straight-through cable
2 – Ethernet Crossover cable
3 – Serial cable
4 – Rollover cable
E. 1 – Ethernet straight-through cable
2 – Ethernet Crossover cable
3 – Serial cable
4 – Ethernet Straight-through cable
Answer: B
Explanation: When connecting a PC to a switch, a standard Ethernet straight through cable should be
used. This same cable should also be used for switch to router connections. Generally speaking, crossover cables are only needed when connecting two like devices (PC-PC,
switch-switch, router-router, etc).
Routers connect to frame relay and other WAN networks using serial cables. Rollover cables are special cables used for connecting to the console ports of Cisco devices.

300-115 Exam Dumps PDF Question No : 7 – (Topic 1) Refer to the exhibit.
SwitchA receives the frame with the addressing shown. According to the command output
also shown in the exhibit, how will SwitchA handle this frame?
A. It will drop the frame.
B. It will forward the frame out port Fa0/6 only.
C. It will flood the frame out all ports.
D. It will flood the frame out all ports except Fa0/3.
Answer: B
Explanation:
Switches keep the learned MAC addresses in a table, so that when a frame comes in with
a destination MAC address that the switch has already learned, it will forward it to that port
only. If a frame comes in with a destination MAC that is not already in the MAC address
table, then the frame will be flooded to all ports except for the one that it came in on. In this
case, Switch A already knows that 00b0.d0da.cb56 resides on port fa0/6, so it will forward
the from out that port.

300-115 Exam Dumps PDF Question No : 8 – (Topic 1) Which statements accurately describe CDP? (Choose three.)
A. CDP is an IEEE standard protocol.
B. CDP is a Cisco proprietary protocol.
C. CDP is a datalink layer protocol.
D. CDP is a network layer protocol.
E. CDP can discover directly connected neighboring Cisco devices.
F. CDP can discover Cisco devices that are not directly connected.
Answer: B,C,E
Explanation:
CDP (Cisco Discovery Protocol) is a proprietary protocol designed by Cisco to help
administrators collect information about both locally attached and remote devices. By using
CDP, you can gather hardware and protocol information about neighbor devices containing
useful info for troubleshooting and documenting the network.
