S± one po angielsku wiec to dodatkowa trudnosc :-/ jesli by ktos byl w stanie mi pomoc, to bardzo prosze1. Host A send 1000 bytes of Telnet data to host B. What does host B send back if it only received the first 500 bytes?
• Source 23 destination 49321 Seq 1000 Ack 500
• Source 23 destination 49321 Seq 500 Ack 1000
• Source 23 destination 49321 Seq 500 Ack 500
• Source 23 destination 49321 Seq 1000 Ack 501
• Source 23 destination 49321 Seq 501 Ack 1000
• Source 23 destination 49321 Seq 501 Ack 501
2. Refer to the exhibit. Host A is unable to reach the remote network, On the basis of the provided output, what is the cause of the problem?
• Host A is configured with incorrect IP address
• Host A is configured with an incorrect default gateway IP address
• There is no path to the remote network in the routing table of
router R1
• Given that the destination network has a subnet mask of /16, host
A and interface Fa0/1 of R1 are both configured with an incorrect
subnet mask
3. Which topology divides the collision domain and provides full media bandwidth to the hosts in the network?
4. Which physical connector type is used for serial V.35 connection to the CSU/DSU?
5. Refer to the exhibit. Which Layer 2 protocol could be used inside network A and network C?
• IP
• TCP
• UDP
• Ethernet
6. Which statement is true about Layer 3 addresses?
• They are physical addresses
• They are use in routing decision
• They are only used on local network
• They are altered each time a packet crosses a router
7. Refer to the exhibit. A network technician has made several changes to R1 since the configuration has last been saved. The modified configuration did not produce the desired changes. The technician wants to store a backup copy of the saved configuration on a TFTP server before reloading. Which action will cause the unmodified data to be saved on the TFTP server?
ODPOWIEDZI:
8. Which OSI Layer addressing is required to route packets between two networks?
• Layer 1
• Layer2
• Layer 3
• Layer 4
9. A user enters http://www.cisco.com/web1.htm in the address line of browser. Which statement is true about this transaction?
• The “http” portion indicates the protocol that is being used
• The “web1.htm” portion is the specific service name
• The retrieved web page will display in URL code
• The “www.cisco.com” is the name of web pages file that is called
10. Refer to the exhibit. An administrator made several changes to the configuration of the router but did not accomplish the desired result. To undo the changes the reload command was used. What will happen if the administrator answers “yes” to the prompt?
• The changes will be lost and the configuration file in RAM will be loaded
• The changes will be saved and the configuration file in RAM will be loaded
• The changes will be lost and the configuration file in NVRAM will be loaded
• The changes will be saved and the configuration file in NVRAM will be loaded
11. Which topology represent a collision-free environment?
12. Refer to the exhibit. A web browser running on host PC1 sends a request for a web page to the web server with IP address 192.168.1.254/24. What sequence of steps will follow in order to establish the session before data can be exchanged?
ODP:
• The session will be initiated using UDP. No additional acknowledgment will be required to establish the session.
• The session will be initiated using TCP. No additional acknowledgment will be required to establish the session.
• The session will be initiated using UDP. The returned web page will serve as an acknowledgment for session establishment
• The session will be initiated using TCP. A three-way handshake must be successfully completed before the session is established
13. What information is used at each hop to determine where the packet will be forward next?
• the IP packet header
• the incoming interface
• the transport layer PDU
• the source MAC
14. Which physical component is used to access and perform the initial configuration on a new unconfigured router?
15. Which fiber connector support full-duplex Ethernet?
16. If administrator wished to return a router to the default state, what additional step must be taken after issuing the command erase?????????????????????????????????
Tu niestety nie mam mozliwych odpowiedzi, ale moze ktos bedzie wiedzial
17. Refer to the exhibit. How will data files retrieved from the server?
• The clients establishes two-way connection to the serer on port 21for file transfer
• From the perspective of computer A, port 21 is used to signal a push to the server, and port 20 is used to signal a pull from the server
• There is a connection established to send file from the client to the server and a second connection to get file from the server to the client.
• Computer A established a connection to the server on port 21 for control and uses a second connection on port 20 to download and upload files
