This Exam contains:
-Guarantee passing score -100 Questions and Answers -format set of multiple-choice -Expert-Verified Explanation Question 1: Users are reporting longer delays in authentication and in accessing network resources during certain time periods of the week. What kind of information should network engineers check to find out if this situation is part of a normal network behavior?
Answer:
the network performance baseline Question 2: Refer to the exhibit. If Host1 were to transfer a file to the server, what layers of the TCP/IP model would be used?(no pic)
Answer:
application, transport, Internet, and network access layers Question 3: An IPv6 enabled device sends a data packet with the destination address of FF02::2.What is the target of this packet?
Answer:
all IPv6 configured routers on the local link
Question 4: A client is using SLAAC to obtain an IPv6 address for its interface. After an address has been generated and applied to the interface, what must the client do before it can begin to use this IPv6 address?
Answer:
It must send an ICMPv6 Neighbor Solicitation message to ensure that the address is not already in use on the network.Question 5: A network administrator wants to have the same network mask for all networks at a particular small site. The site has the following networks and number of devices: IP phones - 22 addressesPCs - 20 addresses neededPrinters - 2 addresses neededScanners - 2 addresses needed The network administrator has deemed that 192.168.10.0/24 is to be the network used at this site. Which single subnet mask would make the most efficient use of the available addresses to use for the four subnetworks?
Answer:
255.255.255.224
Question 6: What characteristic describes a Trojan horse?
Answer:
malicious software or code running on an end device Question 7: What three requirements are defined by the protocols used in network communcations to allow message transmission across a network? (Choose three.)
Answer:
-message encoding -delivery options -message size Question 8: Refer to the exhibit. The network administrator has assigned the LAN of LBMISS an address range of 192.168.10.0. This address range has been subnetted using a /29 prefix. In order to accommodate a new building, the technician has decided to use the fifth subnet for configuring the new network (subnet zero is the first subnet). By company policies, the router interface is always assigned the first usable host address and the workgroup server is given the last usable host address. Which configuration should be entered into the properties of the workgroup server to allow connectivity to the Internet?(no pic)
Answer:
IP address: 192.168.10.38 subnet mask: 255.255.255.248, default gateway: 192.168.10.33
Question 9: What is a function of the data link layer?
Answer:
provides for the exchange of frames over a common local media Question 10: A host is trying to send a packet to a device on a remote LAN segment, but there are currently no mappings in its ARP cache. How will the device obtain a destination MAC address?
Answer:
It will send an ARP request for the MAC address of the default gateway.Question 11: Data is being sent from a source PC to a destination server. Which three statements correctly describe the function of TCP or UDP in this situation? (Choose three.)
Answer:
-The source port field identifies the running application or service that will handle data returning to the PC.-UDP segments are encapsulated within IP packets for transport across the network.-The UDP destination port number identifies the application or service on the server which will handle the data.Question 12: What is an advantage to using a protocol that is defined by an open standard?
Answer:
It encourages competition and promotes choices.Question 13: Match each type of frame field to its function. (Not all options are used.)
Answer:
- Question 14: A user is complaining that an external web page is taking longer than normal to load.The web page does eventually load on the user machine. Which tool should the technician use with administrator privileges in order to locate where the issue is in the network?
Answer:
tracert Question 15: Match each description with the corresponding TCP mechanism. (Not all options are used.)
Answer:
-
Question 16: What is the subnet ID associated with the IPv6 address
2001:DA48:FC5:A4:3D1B::1/64?
Answer:
2001:DA48:FC5:A4::/64
Question 17: Refer to the exhibit. The switches are in their default configuration. Host A needs to communicate with host D, but host A does not have the MAC address for its default gateway.Which network hosts will receive the ARP request sent by host A?(no pic)
Answer:
only hosts B, C, and router R1
Question 18: What is one main characteristic of the data link layer?
Answer:
It shields the upper layer protocol from being aware of the physical medium to be used in the communication.Question 19: Refer to the exhibit. The IP address of which device interface should be used as the default gateway setting of host H1?
Answer:
R1: G0/0
Question 20: Refer to the exhibit. An administrator is trying to configure the switch but receives the error message that is displayed in the exhibit. What is the problem?
------------------------------------------------------
Switch> config t ^ % Invalid input detected at '^' marker.
------------------------------------------------------
Answer:
The administrator must first enter privileged EXEC mode before issuing the command.Question 21: Three bank employees are using the corporate network. The first employee uses a web browser to view a company web page in order to read some announcements. The second employee accesses the corporate database to perform some financial transactions. The third employee participates in an important live audio conference with other corporate managers in branch offices. If QoS is implemented on this network, what will be the priorities from highest to lowest of the different data types?
