IP address management (IPAM) is software that can plan, track, and manage the IP addresses used in a computer network. IPAM integrates Domain Name System (DNS) and Dynamic Host Configuration Protocol (DHCP) so that each is aware of changes in the other; for instance, DNS identifies the IP address of a client via DHCP and updates its database accordingly.
Question 9 of 90 Which of the following technologies can provide a 1000BASE-LX standard connection to the customer premises? Answers A. Metropolitan Ethernet B. DSL C. Dial-up D. Cable broadband
A.
Metropolitan Ethernet
Metropolitan Ethernet, also known as Metro Ethernet is a WAN technology that is based on the Ethernet standard, which traditionally is a LAN technology. It is commonly used to connect subscribers to a larger service network or the Internet. Businesses can also use Metro Ethernet to connect their own offices to each other. Because Ethernet standards are used, a telco may provide an Ethernet based 1000BASE-LX or 10GBASE-LX standard connection to the customer’s premises.

E.
1, 2, 3
C.
1, 2, 5
Internet Protocol (IP) is the principle network layer protocol used on the Internet for relaying datagrams, called packets at the network layer, from source to destination. IP addresses must be globally unique, and the IP protocol is largely responsible for the routing process. IP does not provide error correcting mechanisms, nor does it establish a session. These functionalities are found at higher layers of the OSI model.
Question 13 of 90
What would be the key reason for which Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) is used with Wi-Fi networks? [Choose two that apply.]
Answers
A. Collision detection is impossible in a wireless network. B. Collision Detection is implemented on a wired medium by detecting higher than normal voltages on an Ethernet cable. C. Collision Avoidance cannot be implemented on a wired network. D. Collision Avoidance has less overhead than Collision Detection.
B.
Collision Detection is implemented on a wired medium by detecting higher than normal voltages on an Ethernet cable.
C.
Collision Avoidance cannot be implemented on a wired network.
Collision detection is accomplished on a wired medium by detecting higher than normal voltages on an Ethernet cable that are produced by collisions. The wireless medium does not produce a similar phenomenon when collisions occur. So, collision detection is impossible. Collision avoidance mechanisms however are employed to deal with such occurrences on the wireless medium.

You can either upgrade the wireless network to 802.11a or 802.11n. The 802.11a specification works at 5GHz and the 802.11n specification works at 2.4 and 5 GHz. You will need to make it work at 5 GHz.
Question 28 of 90 A large enterprise is moving to a new complex and is designing the network that will serve its new buildings. The buildings are all within a five-kilometer radius and are built on privately owned grounds. The network will interconnect the buildings using privately owned cabling and network equipment. What type of network is this enterprise developing? Answers A. Campus Area Network (CAN) B. Wide Area Network (WAN) C. Metropolitan Area Network (MAN) D. Enterprise Area Network (EAN) E. Local Area Network (LAN)
A.
Campus Area Network (CAN)
A Campus Area Network (CAN), also known as a Corporate Area Network, is a computer network made up of an interconnection of LANs within a limited geographical area. Networking equipment (switches, routers) as well as transmission media (copper cabling, optical fiber) are almost always entirely owned by the campus tenant o owner. A CAN is generally larger than a LAN and smaller than a MAN.
Question 35 of 90
You are comparing two types of networks:
A network that creates a dedicated communication path between the communicating devices. This path is maintained until the communication ends. A network where data is grouped into packets that are sent individually over a network. Each packet is directed independently based on the addressing information found in its header. Which of the following comparisons are true?
[Choose two that apply.]
Answers
A. (2) requires the initial establishment of a connection while (1) does not B. (2) is more reliable than (1) C. (2) is more efficient and uses fewer network resources than (1) D. Delay between data units is uniform for (1) but not for (2)
C.
(2) is more efficient and uses fewer network resources than (1)
D.
Delay between data units is uniform for (1) but not for (2)
(1) Describes a circuit-switched network which initially establishes a dedicated communication path between the communicating devices which is maintained until the communication ends. The traditional Public Switched Telephone Network (PSTN) is one such network. (2) describes a packet-switched network which is one where data is grouped into packets that are sent individually over a network. Each packet is directed over the network independently based on the addressing information found in its header. Modern IP-based networks are packet-switched networks.
Question 36 of 90 You are provided with a fiber optic link of four kilometers using a single pair of single mode fiber optic strands. Which of the following Ethernet deployment standard would you use to achieve 1 Gbps speeds while keeping costs at a minimum? Answers A. 100BASE-LX B. 1000BASE-TX C. 1000BASE-SX D. 1000BASE-LX
D.
1000BASE-LX
1000BASE-LX is a fiber optic Gigabit Ethernet standard specified in IEEE 802.3. 1000BASE-LX is specified to work over up to 5 km over 10 µm single-mode fiber. Although the 10GBASE-T standard would also suffice for this application, it is by far a more expensive solution, so the best choice would be 1000BASE-LX.
uestion 38 of 90 You are a network administrator for an organization. You are asked to create a shared folder on a Microsoft Windows system so that other users on the same network are able to access its contents. To be able to meet this requirement, which protocol is likely to be used? Answers A. SMBP with port 445 B. NetBIOS with port 445 C. SMB with port 445 D. FTP with port 445
C.
SMB with port 445
Server Message Block (SMB) is an application layer network protocol used primarily for providing shared access to files, printers and serial ports between nodes on a network. It is mostly used on computers running Microsoft Windows although similar versions such as Samba have been developed for Unix-like operating systems as well. SMB uses port 445.
Question 46 of 90 You want to implement a network that provides a data carrying technique to direct traffic from one network node to the next based on short path labels rather than long network addresses. The network should avoid complex lookups in a routing table. Which of the following network should you implement? Answers A. Frame Relay B. ATM C. PPPoE D. MPLS
D.
MPLS
Multiprotocol Label Switching (MPLS) is a type of data-carrying technique for high-performance telecommunications networks. MPLS directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links between distant nodes rather than endpoints. MPLS can encapsulate packets of various network protocols, hence its name multiprotocol.
Question 51 of 90 You are asked to determine which Ethernet deployment standard should be used to interconnect a telecom closet on the 10th floor of a building to the data center found on the first floor. Maximum speeds required are 1000 Mbps while multi-mode fiber is used for this link with a total cable length of no more than 450 meters. What would be the best choice? Answers A. 1000BASE-LX B. 1000BASE-TX C. 100BASE-LX D. 1000BASE-SX
D.
1000BASE-SX
1000BASE-SX is an optical fiber Gigabit Ethernet standard for operation over multi-mode fiber. The standard specifies a maximum length of 550 depending on the type of multi-mode fiber used, however, in practice, with good quality fiber, optics, and terminations, 1000BASE-SX will usually work over significantly longer distances. Although the 10GBASE-T standard would also suffice for this application, it would be considered overkill so the best choice would be 1000BASE-SX.
