  A. Ping
  B. Nessus
  C. IMAP
  D. Telnet
  B. Nessus

  B. A successful WPS attack has occurred.
  C. The user is experiencing ARP poisoning.
  D. The user is connected to a botnet.
  B. A successful WPS attack has occurred.

• Question 1313:

  Which of the following OSI model layers is used to order packets which may have arrived out of order?

  A. Transport
  B. Presentation
  C. Network
  D. Session
  A. Transport

• Question 1314:

  Which of the following network protocols is used to resolve FQDNs to IP addresses?

  A. DNS
  B. FTP
  C. DHCP
  D. APIPA
  A. DNS

  ---

  Explanation Explanation/Reference:An Internet service that translates domain names into IP addresses. Because domain names are alphabetic, they're easier to remember. The Internet however, is really based on IP addresses. Every time you use a domain name, therefore, a DNS service must translate the name into the corresponding IP address. For example, the domain name www.example.com might translate to 198.105.232.4.

• Question 1315:

  Which of the following is used to authenticate remote workers who connect from offsite? (Select TWO).

  A. OSPF
  B. VTP trunking
  C. Virtual PBX
  D. RADIUS
  E. 802.1x
  D. RADIUS
  E. 802.1x

  ---

  D: A RADIUS (Remote Authentication Dial-in User Service)server is a server with a database of user accounts and passwords used as a central authentication database for users requiring network access. RADIUS servers are commonly used by ISP's to authenticate their customer's Internet connections. Remote users connect to one or more Remote Access Servers. The remote access servers then forward the authentication requests to the central RADIUS server. E: 802.1X is an IEEE Standard for Port-based Network Access Control (PNAC). It provides an authentication mechanism to devices wishing to attach to a network. 802.1X authentication involves three parties: a supplicant, an authenticator, and an authentication server. The supplicant is a client that wishes to attach to the network. The authenticator is a network device,such as an Ethernet switch, wireless access point or in this case, a remote access server and the authentication server is the RADIUS server.

• Question 1316:

  Which of the following is the control when observing network bandwidth patterns over time?

  A. Network log
  B. Baseline
  C. Flow data
  D. Interface statistics
  B. Baseline

  ---

  To successfully baseline a network it is important to consider two functions; performance at protocol level and performance at application level. There are many significant metrics to consider at the protocol level, but only a few which are critical. The most important is bandwidth utilization compared with bandwidth availability. The most likely cause of poor network performance is insufficient bandwidth. Trending bandwidth utilization allows you to recognize problem areas, provide enough bandwidth to reach performance objectives, and predict future capacity requirements. Changes in bandwidth utilization patterns also provide a clear indication of network usage alterations, such as a change in end-user behavior, or the unauthorized addition of an application.

• Question 1317:

  A technician is trying to configure a previously owned WAP. The technician successfully logs into the administrative console and attempts to input the IP address on the WAP. However, the WAP is not accepting the command. Which of the following is causing the problem?

  A. The WAP antenna is damaged.
  B. The WAP transmitter light is dim.
  C. The terminal emulation software is misconfigured.
  D. The LWAPP image is installed on the WAP
  C. The terminal emulation software is misconfigured.

• Question 1318:

  Users in an official have noted that when they move away from the WAP, their signal drops off very quickly despite being in an open area. To confirm this, a technician performs a site survey and noted the following:

  WAP

  Distance

  from

  WAP

  RSSI

  AP1

  Under

  -45

  AP1

  20ft

  -61

  AP1

  40ft

  -80

  Which of the following would BEST provide better signal coverage in the area around the WAP?

  A. Install an omnidirectional antenna.
  B. Disable legacy standards on the AP.
  C. Disable MIMO on the AP.
  D. Verify the channel configuration.
  A. Install an omnidirectional antenna.

• Question 1319:

  An administrator notices an unused cable behind a cabinet that is terminated with a DB-9 connector. Which of the following protocols was MOST likely used on this cable?

  A. RS-232
  B. 802.3
  C. ATM
  D. Tokenring
  A. RS-232

  ---

  A DB-9 connector is used on serial cables. Serial cables use the RS-232 protocol which defines the functions of the 9 pins in a DB-9 connector. The RS-232 standard was around long before computers. It's rare to see a new computer nowadays with a serial port but they were commonly used for connecting external analog modems, keyboards and mice to computers.

• Question 1320:

  In a home network, all clients are accessing the Internet via a single host. This is an example of which of the following?

  A. Point-to-multipoint
  B. Peer-to-peer
  C. Partial mesh
  D. Hybrid
  A. Point-to-multipoint
