What are the three primary functions provided by Layer 2 data encapsulation? (Choose three.)
error correction through a collision detection method
Conversion of bits into data signals
Delimiting groups of bits into frames
Detection of errors through CRC calculations
Placement and removal of frames from the media
Data link layer addressing
Session control using port numbers
What information is added during encapsulation at OSI Layer 3?
Source and destination IP address
Source and destination port number
Source and destination application protocol
Source and destination MAC
Why does a Layer 3 device perform the ANDing process on a destination IP address and subnet mask?
To identify the network address of the destination network
To identify faulty frames
To identify the host address of the destination host
To identify the broadcast address of the destination network
Why are port numbers included in the TCP header of a segment?
To indicate the correct router interface that should be used to forward a segment
To identify which switch ports should receive or forward the segment
To determine which Layer 3 protocol should be used to encapsulate the data
To enable a receiving host to forward the data to the appropriate application
To allow the receiving host to assemble the packet in the proper order
What important information is added to the TCP/IP transport layer header to ensure communication and connectivity with a remote network device?
Timing and synchronization
Destination and source port numbers
Destination and source physical addresses
Destination and source logical network addresses
What are two ways that TCP uses the sequence numbers in a segment?(Choose two.)
To specify the order in which the segments travel from source to destination
To reassemble the segments at the remote location
To identify missing segments at the destination
To limit the number of segments that can be sent out of an interface at one time
To determine if the packet changed during transit
Which three statements characterize UDP? (Choose three.)
UDP provides basic connectionless transport layer functions.
UDP provides connection-oriented, fast transport of data at Layer 3.
UDP relies on application layer protocols for error detection.
UDP is a low overhead protocol that does not provide sequencing or flow control mechanisms
UDP relies on IP for error detection and recovery.
UDP provides sophisticated flow control mechanisms.
Refer to the exhibit. An administrator is testing connectivity to a remote device with the IP address 10.1.1.1. What does the output of this command indicate?
Connectivity to the remote device was successful.
A router along the path did not have a route to the destination.
A ping packet is being blocked by a security device along the path.
The connection timed out while waiting for a reply from the remote device.
Under which two circumstances will a switch flood a frame out of every port except the port that the frame was received on? (Choose two.)
The frame has the broadcast address as the destination address.
The destination address is unknown to the switch.
The source address in the frame header is the broadcast address.
The source address in the frame is a multicast address.
The destination address in the frame is a known unicast address.
What is the purpose of the command ping ::1?
It tests the internal configuration of an IPv6 host.
It tests the broadcast capability of all hosts on the subnet
It tests the multicast connectivity to all hosts on the subnet.
It tests the reachability of the default gateway for the network.
What is one difference between the client-server and peer-to-peer network models?
Only in the client-server model can file transfers occur.
Every device in a peer-to-peer network can function as a client or a server.
A peer-to-peer network transfers data faster than a transfer using a client-server network.
A data transfer that uses a device serving in a client role requires that a dedicated server be present.
A network engineer is analyzing reports from a recently performed network baseline. Which situation would depict a possible latency issue?
A change in the bandwidth according to the show interfaces output
A next-hop timeout from a traceroute
An increase in host-to-host ping response times
A change in the amount of RAM according to the show version output
What are three characteristics of an SVI? (Choose three.)
It is designed as a security protocol to protect switch ports
It is not associated with any physical interface on a switch
It is a special interface that allows connectivity by different types of media
It is required to allow connectivity by any device at any location.
It provides a means to remotely manage a switch
It is associated with VLAN1 by default.
A DHCP server is used to IP addresses dynamically to the hosts on a network. The address pool is configured with 10.29.244.0/25. There are 19 printers on this network that need to use reserve static IP addresses from the pool. How many IP address in the pool are left to be assign to other hosts?
