DMZ
Explanation: Your best option would be to identify DMZ. The demilitarized zone is a small network between the internal network and the Internet that offers a layer of security and privacy. DMZ is thus a method for placing web and other servers that serve the general public outside the firewall isolating them from the internal network access. Incorrect Answers: A: PAP is one of the simplest forms of authentication. Authentication is accomplished by sending usernames and passwords to the server where it is verified. The passwords are sent as clear text. You can easily detect if it is intercepted. B: A Virtual Private Network (VPN) makes use of the public Internet as a backbone for a private interconnection between locations. This technology supports reasonably secure, logical, private network links and insecure public network infrastructure. It reduces the Public Switched Telephone Network (PSTN) costs. VPNs are more secure that the traditional remote access as it can be encrypted. D: Point-to-Point Tunne |

to the email server. Which of the following commands would the user type in at the command prompt to display the MAC address? A. ipconfig B. arp -s C. arp -a D. nbtstat R |
arp -a
Explanation: The Address Resolution Protocol, or ARP, is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol stack; it is used to translate TCP/IP addresses to MAC (media access control) addresses using broadcasts. When a machine running TCP/IP wants to know which machine on an Ethernet network uses a particular IP address, it will send an ARP broadcast that says, in effect, "Hey! Who is IP address xxx.xxx.xxx.xxx ?" The machine that owns the specific address will respond with its own MAC address. The machine that made the inquiry then adds that information to its own ARP table. In addition to the normal usage, the ARP designation refers to a utility in Windows that you can use to manipulate and view the local workstation's ARP table. To display the entire current ARP table, use the Arp command with the -a switch, like this: arp -a Incorrect Answers: A: You should not consider making use of the ipconfig utility because the ipconfig utility cannot be used to solve the proble |

|
Which of the following is a utility that translates the physical network address to its IP address?
A. nslookup B. ping C. rarp D. netstat |
rarp
Explanation: Reverse ARP (RARP) is nothing more than ARP packets with different codes in the header, indicating to devices receiving RARP packets that these are requests by the source device for its own IP configuration, meaning RARP replies should be handled by a RARP server and that any device not fulfilling this role need not process these requests any further. If, however, the receiving device is a RARP server, it is incumbent upon that device to find the requesting device's MAC address in a configured list (RARP is an older, manual process, unlike DHCP). The server sends the IP address it finds associated with the requesting MAC address back to the requesting device. RARP was adequate for diskless workstation initial IP configuration but fell short as a be-all, endall supplier of detailed IP-related information, which is why DHCP has supplanted RARP for supplying network-based IP configuration in most modern networks. Incorrect Answers: A: You should not consider making use of the nslookup utilit |

A. PPP B. HTTPS C. PPTP D. SSH |
PPTP
Explanation: Point-to-Point Tunneling Protocol You can access a private network through the Internet or other public network by using a virtual private network (VPN) connection with the Point-to-Point Tunneling Protocol (PPTP). Developed as an extension of the Point-to-Point Protocol (PPP), PPTP tunnels and/or encapsulates IP, IPX, or NetBEUI protocols inside of PPP datagram's. PPTP does not require a dial-up connection. It does, however, require IP connectivity between your computer and the server. Not B: L2TP is an industry-standard Internet tunneling protocol with roughly the same functionality as the Point-to-Point Tunneling Protocol (PPTP). Like PPTP, L2TP encapsulates Point-to-Point Protocol (PPP) frames, which in turn encapsulate IP, IPX, or NetBEUI protocol.

Replace RIP with alinkstate
routing protocol such as OSPF.

Incorrect Answers: A: In the scenario you should not consider making use of RIPv2 as RIP-2 makes use of distance vector logic; uses hop count for the metric whilst sending full, periodic updates; and still converges relatively slowly. You should additionally remember that RIP-2 does add support for VLSM, as compared with RIP-1, making it a classless routing protocol. B: In the scenario you should not consider BGP as the Border Gateway Protocol (BGP) is designed specifically for use between two different organizations. You should additionally remember that BGP distributes routing information between ISPs worldwide today and be |

Which of the following cable types is typically used to connect a hub to a hub that does not support
MDIX? A. Straight B. Loopback C. Crossover D. Rollover |

Which of the following features from the switch eliminates a delay in acquiring an IP address?
A. Update the SNMP strings. B. Change the duplex mode tohalfduplex. C. Enable spanning tree on the interface. D. Enable trunking |
Enable spanning tree on the interface.
Explanation: Your best option in this scenario would be to enable spanning tree on the interface. The spanningtree algorithm places every bridge or switch port into either a forwarding state or a blocking state. It ensures that only one path is active between two network stations. It also permits redundant paths that are automatically activated when the active path experiences problems. |

Which of the following is the component in a wiring system designed to support legacy phone
systems? A. Fiber conduit B. 66 block C. 110 block D. Patch panels |
66 block
Explanation: Currently, 66 blocks are considered legacy devices. They are large, compared to more contemporary wire terminating devices, and, due to their maximum 16 MHz Category 3 signaling compatibility, are all suited for high speed data circuits greater than 10Base-T. |

|
Which of the following protocols allows usernames and passwords to be transmitted as cleartext?
A. PAP B. RADIUS C. CHAP D. SSH |
PAP
Explanation: Of all the authentication schemes in use today, the Password Authentication Protocol (PAP) is arguably the simplest. In PAP, pairs of usernames and passwords are used. When a client wants to authentication to a server, for example, the client will send the username and password to the server over the network. The username and password are sent in clear text, that is to say, unencrypted. The server receives the username and password and compares them to an encrypted, locally stored table of username-password pairs. If the username and password is a match, the client is authenticated. |

When preparing to place a RJ45
connector on a CAT5 cable, which of the following tools would BEST be used to prepare the cable? A. Polishing kit B. Pliers C. Razor knife D. Snips |

|
Which of the following authentication protocols uses certificates to negotiate access to the
network? A. EAPTLS B. PAP C. CHAP D. Kerberos |
EAPTLS
Incorrect Answers: B: You should not consider making use of the PAP protocol because PAP pairs the usernames and passwords which are used. You should also remember when a client wants to authentication to a server the client will send the username and password to the server over the network. C: You should not consider making use of the Challenge Handshake Authentication Protocol (CHAP) because the protocol requires having both the client and server configured with the same text phrase or known as a shared secret. The server would then compare the hash received from the client with the hash value it calculated when a match is verified the client is authenticated. D: You should not consider making use of the Kerberos protocol as is not just a protocol but an entire security system. Kerberos is used to establish a user's identity when they log on to a system that uses Kerberos. Kerberos then has that identity and its security credentials are then used throughout an entire logon session. Kerberos additio |

A network administrator of a company has many branch locations each using a subnet mask of
255.255.255.224. Which of the following dynamic routing protocols should be used? A. RIPv2 B. IGRP C. ISIS D. BGP |
RIPv2
Explanation: In the scenario you should consider making use of RIPv2 as RIP-2 makes use of distance vector logic; uses hop count for the metric whilst sending full, periodic updates; and still converges relatively slowly. You should additionally remember that RIP-2 does add support for VLSM, as compared with RIP-1, making it a classless routing protocol. |
