Question 1 of 54
1. Question
1 pointsA company is expanding its business to other countries. All branch offices must remain connected to corporate headquarters at all times. Which network technology is required to support this requirement?Correct
Incorrect
A local-area network (LAN) normally connects end users and network resources over a limited geographic area using Ethernet technology. A wireless LAN (WLAN) serves the same purpose as a LAN but uses wireless technologies. A metropolitan-area network (MAN) spans a larger geographic area such as a city, and a wide-area network (WAN) connects networks together over a large geographic area. WANs can span cities, countries, or the globe.

4. Question
1 pointsOn which switch interface would an administrator configure an IP address so that the switch can be managed remotely?Correct
Incorrect
Interface VLAN 1 is a virtual interface on a switch, called SVI (switch virtual interface). Configuring an IP address on the default SVI, interface VLAN 1, will allow a switch to be accessed remotely. The VTY line must also be configured to allow remote access, but an IP address cannot be configured on this line.Hint

Question 6 of 54
6. Question
1 pointsRefer to the exhibit. A network administrator is configuring access control to switch SW1. If the administrator has already logged into a Telnet session on the switch, which password is needed to access privileged EXEC mode?
ITN Final Exam Form C Answers 001 Correct
Incorrect
Telnet accesses a network device through the virtual interface configured with the line VTY command. The password configured under this is required to access the user EXEC mode. The password configured under the line console 0 command is required to gain entry through the console port, and the enable and enable secret passwords are used to allow entry into the privileged EXEC mode.Hint

Question 21 of 54
21. Question
3 pointsWhat are the three primary functions provided by Layer 2 data encapsulation? (Choose three.)Correct
Incorrect
Through the framing process, delimiters are used to identify the start and end of the sequence of bits that make up a frame. Data link layer addressing is added to enable a frame to be delivered to a destination node. A cyclic redundancy check (CRC) field is calculated on every bit and added to the frame. If the CRC value contained in the arriving frame is the same as the one the receiving node creates, the frame will be processed.Hint

Question 24 of 54
24. Question
1 pointsWhat will a host on an Ethernet network do if it receives a frame with a destination MAC address that does not match its own MAC address?Correct
Incorrect
In an Ethernet network, each NIC in the network checks every arriving frame to see if the destination MAC address in the frame matches its own MAC address. If there is no match, the device discards the frame. If there is a match, the NIC passes the frame up to the next OSI layer.Hint

Question 26 of 54
26. Question
1 pointsWhich switching method has the lowest level of latency?Correct
Incorrect
Fast-forward switching begins to forward a frame after reading the destination MAC address, resulting in the lowest latency. Fragment-free reads the first 64 bytes before forwarding. Store-and-forward has the highest latency because it reads the entire frame before beginning to forward it. Both fragment-free and fast-forward are types of cut-through switching.Hint

Question 37 of 54
37. Question
1 pointsA network administrator wants to have the same subnet mask for three subnetworks at a small site. The site has the following networks and numbers of devices:
Subnetwork A: IP phones – 10 addresses
Subnetwork B: PCs – 8 addresses
Subnetwork C: Printers – 2 addressesWhat single subnet mask would be appropriate to use for the three subnetworks?
Correct
Incorrect
If the same mask is to be used, then the network with the most hosts must be examined for number of hosts. Because this is 10 hosts, 4 host bits are needed. The /28 or 255.255.255.240 subnet mask would be appropriate to use for these networks. Hint

Question 39 of 54
39. Question
1 pointsWhat subnet mask is needed if an IPv4 network has 40 devices that need IP addresses and address space is not to be wasted?Correct
Incorrect
In order to accommodate 40 devices, 6 host bits are needed. With 6 bits, 64 addresses are possible, but one address is for the subnet number and one address is for a broadcast. This leaves 62 addresses that can be assigned to network devices. The mask associated with leaving 6 host bits for addressing is 255.255.255.192.Hint

Question 40 of 54
40. Question
2 pointsWhat are two characteristics shared by TCP and UDP? (Choose two.)Correct
Incorrect
Both TCP and UDP use source and destination port numbers to distinguish different data streams and to forward the right data segments to the right applications. Error checking the header and data is done by both protocols by using a checksum calculation to determine the integrity of the data that is received. TCP is connection-oriented and uses a 3-way handshake to establish an initial connection. TCP also uses window to regulate the amount of traffic sent before receiving an acknowledgment. UDP is connectionless and is the best protocol for carry digitized VoIP signals.Hint

Question 45 of 54
45. Question
1 pointsWhat is one difference between the client-server and peer-to-peer network models?Correct
Incorrect
Data transfer speeds depend on a number of factors including the amount of traffic, the quality of service imposed, and the network media. Transfer speeds are not dependent on the network model type. File transfers can occur using the client-server model or the peer-to-peer model. A data transfer between a device acting in the client role and a device acting in the server role can occur in both peer-to-peer and client-server networks.Hint

46. Question
1 pointsWhich networking model is being used when an author uploads one chapter document to a file server of a book publisher?Correct
Incorrect
In the client/server network model, a network device assumes the role of server in order to provide a particular service such as file transfer and storage. In the client/server network model, a dedicated server does not have to be used, but if one is present, the network model being used is the client/server model. In contrast, a peer-to-peer network does not have a dedicated server.Hint

1 pointsA wireless host needs to request an IP address. What protocol would be used to process the request?Correct
Incorrect
The DHCP protocol is used to request, issue, and manage IP addressing information. CSMA/CD is the access method used with wired Ethernet. ICMP is used to test connectivity. SNMP is used with network management and FTP is used for file transfer.Hint

1 pointsWhat network service resolves the URL entered on a PC to the IP address of the destination server?Correct
Incorrect
When a client attempts to connect to a website, the destination URL must be resolved to an IP address. To do this the client queries a Domain Name System (DNS) server.Hint

50. Question
1 pointsWhich firewall feature is used to ensure that packets coming into a network are legitimate responses to requests initiated from internal hosts?Correct
Incorrect
Stateful packet inspection on a firewall checks that incoming packets are actually legitimate responses to requests originating from hosts inside the network. Packet filtering can be used to permit or deny access to resources based on IP or MAC address. Application filtering can permit or deny access based on port number. URL filtering is used to permit or deny access based on URL or on keywords.Hint

1 pointsWhat is one indication that a Windows computer did not receive an IPv4 address from a DHCP server?Correct
Incorrect
When a Windows PC cannot communicate with an IPv4 DHCP server, the computer automatically assigns an IP address in the 169.254.0.0/16 range. Any other device on the same network that receives an address in the same range is reachable.Hint
