15. When connectionless protocols are implemented at the lower layers of the OSI model, what is usually used to acknowledge that the data was received and to request the retransmission of missing data?

IP

UDP

Ethernet

A connectionless acknowledgement

An upper-layer, connection-oriented protocol or service

16. What information can be gathered by using the command netstat?

The default gateway

The routing protocol

Active TCP connections

The locally configured subnet mask

17. What happens when a node on an Ethernet network is creating a frame and it does not have the destination MAC address?

The node drops the frame.

The node sends out a Layer 3 broadcast message.

The node sends a message directly to the router for the address.

The node sends out an ARP request with the destination IP address.

18. What is the correct order for PDU encapsulation?

19. What is the protocol data unit that is associated with the data link layer of the OSI reference model?

Data

Frame

Packet

Segment

20. Which identifier is contained in the header of the Layer 2 Ethernet frame?

Timing and synchronization of bits

Source and destination port numbers

Logical source and destination addresses

Physical source and destination addresses

21. Which option shows how a router will route packets to a remote network?

22. An administrator makes changes to the default configuration of a router and saves them to NVRAM. After testing, it is discovered that the configurations did not have the desired effect and must be removed. What steps must be taken to remove the changes and return the router to the default configuration?

Reboot the router.

Use no version of the commands that are issued.

Issue the erase startup-config command, and then reboot the router.

Issue the erase running-config command, and then reboot the router.

23. Refer to the exhibit. Host C is able to ping 127.0.0.1 successfully, but is unable to communicate with hosts A and B in the organization. What is the likely cause of the problem?

Hosts A and B are not on the same subnet as host C.

The IP addresses on the router serial interfaces are wrong.

The subnet mask on host C is improperly configured.

The FastEthernet interface fa0/0 of router 1 is wrongly configured.

24. Which statement identifies the DNS protocol?

It transmits information using TCP port 25.

It transfers and conveys information using HTML pages.

It matches a resource name with the required network address.

It requests and assigns an IP address, default gateway, and server addresses to hosts.

25. What purpose does a hostname serve on a router?

Uniquely identifies a router on the internet

Used by routing protocols to identify peer routers

Provides device identification to users logging on remotely

Determines the hosts that are allowed to connect to the device

26. Which subnet mask will allow 2040 hosts per subnet on the IP network 10.0.0.0?

255.255.0.0

255.255.254.0

255.255.252.0

29. Which statement accurately describes file sharing in a peer-to-peer network?

A dedicated server is required.

Access control is decentralized.

Files are typically stored on the most powerful peer in the network.

Peers can either make requests, or respond to requests, but not both.

30. Two routers are connected via their serial ports in a lab environment. The routers are configured with valid IP addresses, but they cannot ping each other. The show interface serial0/0 command shows that the serial0/0 interface is up but the line protocol is down. What could be the cause of this problem?

The no shutdown command has not been applied to the interfaces.

The clock rate command has not been entered on the DCE interface.

The interface timers are not cleared.

The FastEthernet interface is emulating a serial interface by assigning it a timing signal.
