  A. It can reroute connectivity in the event of failure.
  B. It is the simplest form of routing.
  C. The routes do not change.
  D. The setup and configuration are done manually.
  A. It can reroute connectivity in the event of failure.

• Question 522:

  A technician replaces a failed router in an office with the same model unit using the default settings. After the installation, the technician reboots all of the PCs and servers. Upon reboot some of the PCs are receiving IP addresses on the same subnet as the new router; other PCs are receiving addresses on the same subnet as the servers.

  Which of the following most likely describes the issue?

  A. The DHCP lease pool was not large enough
  B. DHCP lease times were set too low
  C. The router is not the only DHCP server
  D. DHCP was not enabled on the replacement router
  C. The router is not the only DHCP server

  ---

  This happens when there are multiple DHCP servers in the same LAN subnet. Here some machines are getting ip address from the router while some are getting ip address from another DHCP server present in the same domain.

• Question 523:

  Which of the following wireless router security measures provides access to a network by allowing only devices on an approved physical address list?

  A. Port filtering
  B. MAC filtering
  C. SSID masking
  D. Port forwarding
  B. MAC filtering

• Question 524:

  Which of the following protocols would the network administrator use to protect login credentials when accessing a router terminal session?

  A. SCP
  B. SNMPv3
  C. SSL
  D. SSH
  D. SSH

• Question 525:

  A technician has narrowed down the cause of a problem to two possible sources. Which of the following should the technician do NEXT?

  A. Implement a solution for both causes to be sure all possibilities are covered.
  B. Choose the more likely cause and test to confirm.
  C. Establish a plan of action for each.
  D. Choose the less likely cause and test to eliminate.
  B. Choose the more likely cause and test to confirm.

• Question 526:

  Joe, a network technician, is asked to install a couple new WAP's inside a back warehouse that was added to a main warehouse facility that already has complete wireless coverage on both the 2.4GHz and 5GHz frequencies. Joe already has a complete wireless heat map of the main warehouse.

  Which of the following is the first step that Joe should do before choosing which WAP's to use?

  A. Conduct a wireless survey of the back warehouse.
  B. Ask the vendor that provided the WAP's for the main warehouse for recommendations.
  C. Ask the systems administrator which WAP's are preferred.
  D. Only order WAP's that support 5GHz channels.
  A. Conduct a wireless survey of the back warehouse.

• Question 527:

  Which of the following provides the STRONGEST security for a tunneled connection over the Internet?

  A. RDP
  B. SMTP
  C. RAS
  D. IPSec
  D. IPSec

• Question 528:

  An administrator is attempting to troubleshoot a program that is unable to resolve IP addresses from FQDNs. Which of the following commands is used to check reverse DNS settings?

  A. dig
  B. ifconfig
  C. nbtstat
  D. route
  A. dig

• Question 529:

  A technician needs to restrict access to a SOHO wireless network to specific devices. Which of the following would MOST likely be used with minimal client configuration?

  A. Port filtering
  B. WEP
  C. MAC address filtering
  D. PoE
  C. MAC address filtering

• Question 530:

  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.
