   Which of the following needs to be tested to achieve a Cat 6a certification for a company's data cabling?

   • ARJ11
   • BLC ports
   • CPatch panel
   • DF-type connector

   Show answer

   Answer: C

   Explanation

   To achieve a Cat 6a certification for a company's data cabling, the patch panel needs to be tested. A patch panel is a device that allows cables to be terminated and then connected to a switch, router, or other networking device. It is a central location for all of the incoming and outgoing cabling for a network. When certifying a Cat 6a cabling installation, the patch panel needs to be tested to ensure that it meets the standards for Cat 6a performance. Option A, RJ11, is a connector used for telephone cables and is not used in Cat 6a cabling. Option B, LC ports, are fiber optic connectors and are not used in Cat 6a cabling. Option D, F-type connector, is a coaxial connector used for cable TV and is not used in Cat 6a cabling.

   Which of the following would be used to forward requests and replies between a DHCP server and client?

   • ARelay
   • BLease
   • CScope
   • DRange

   Show answer

   Answer: A

   Explanation

   A relay would be used to forward requests and replies between a DHCP (Dynamic Host Configuration Protocol) server and client. In networking, a relay is a device that receives incoming messages and then forwards them to their destination. In the context of DHCP, a relay is a device that receives DHCP requests from clients on one network and then forwards them to the DHCP server on another network. This is useful when the client and server are not on the same network and cannot communicate directly. The relay helps to ensure that the client can still receive a valid IP address and other configuration information from the server.

5. Question 145 · 871 in bank

   Network connectivity in an extensive forest reserve was achieved using fiber optics. A network fault was detected, and now the repair team needs to check the integrity of the fiber cable. Which of the following actions can reduce repair time?

   • AUsing a tone generator and wire map to determine the fault location
   • BUsing a multimeter to locate the fault point
   • CUsing an OTDR in one end of the optic cable to get the fiber length information
   • DUsing a spectrum analyzer and comparing the current wavelength with a working baseline

   Show answer

   Answer: C

   Explanation

   Using an OTDR (Optical Time Domain Reflectometer) is the most effective way to reduce repair time when trying to locate a fault in a fiber optic cable. The OTDR sends a pulse of light down the fiber optic cable and measures the time it takes for the light to be reflected back. By analyzing the reflections, the OTDR can determine the location of any faults or breaks in the cable. This allows the repair team to quickly and accurately locate the fault point, which can significantly reduce the time needed for repairs.

7. Question 147 · 871 in bank

   A small office has a wireless network with several access points that are used by mobile devices. Users occasionally report that the wireless connection drops or becomes very slow. Reports confirm that this only happens when the devices are connected to the office wireless network. Which of the following is MOST likely the cause?

   • AThe configuration of the encryption protocol
   • BInterference from other devices
   • CInsufficient bandwidth capacity
   • DDuplicate SSIDs

   Show answer

   Answer: B

   Explanation

   The correct answer is B. Users may be experiencing RF interference from other devices that are transmitting radio waves in the same frequencies that their personal devices are using to communicate. Answer A is incorrect because encryption mismatch would cause no connectivity. Answer C is incorrect because users are experiencing the issue only on the wireless network. If it was a bandwidth issue, then all users would be experiencing the same issue. Answer D is incorrect because duplicate SSIDs do not cause intermittent or no connectivity. SSIDs are used only to allow users to find an access point and associate with it to connect to the wireless network. In fact, "duplicate SSIDs" in this question may refer to the ESSID broadcasted by the access points in the area.

   A technician performed a manual reconfiguration of a firewall, and network connectivity was reestablished. Some connection events that were previously sent to a syslog server are no longer being generated by the firewall. Which of the following should the technician perform to fix the issue?

   • AAdjust the proper logging level on the new firewall.
   • BTune the filter for logging the severity level on the syslog server.
   • CActivate NetFlow traffic between the syslog server and the firewall.
   • DRestart the SNMP service running on the syslog server.

   Show answer

   Answer: A

   Explanation

   The correct answer is A. Adjust the proper logging level on the new firewall. If the firewall has been manually reconfigured, it's possible that the logging level has been changed or disabled, which could explain why connection events are no longer being generated. The technician should check the logging configuration on the firewall and adjust it as necessary to ensure that the desired events are being logged.

    A company rents out a large event space and includes wireless internet access for each tenant. Tenants reserve a two-hour window from the company each week, which includes a tenant-specific SSID. However, all users share the company's network hardware. The network support team is receiving complaints from tenants that some users are unable to connect to the wireless network. Upon investigation, the support team discovers a pattern indicating that after a tenant with a particularly large attendance ends its sessions, tenants throughout the day are unable to connect. The following settings are common to all network configurations:

    

    Which of the following actions would MOST likely reduce this issue? (Choose two.)

    • AChange to WPA encryption.
    • BChange the DNS server to 10.1.10.1.
    • CChange the default gateway to 10.0.0.1.
    • DChange the DHCP scope end to 10.1.10.250.
    • EDisable AP isolation.
    • FChange the subnet mask to 255.255.255.192.
    • GReduce the DHCP lease time to four hours.

    Show answer

    Answer: DG

    Explanation

    When GPT is asked the correct way, it picks (D) and (G): "The TWO actions that would MOST likely reduce the issue of tenants being unable to connect after a large attendance session are: (D) Change the DHCP scope end to 10.1.10.250 (G) Reduce the DHCP lease time to four hours Explanation: (D) Change the DHCP scope end to 10.1.10.250: By increasing the DHCP scope range to include more available IP addresses, you provide a larger pool of addresses for devices to obtain when connecting. This can help avoid running out of available IP addresses during busy times and prevent connectivity issues. (G) Reduce the DHCP lease time to four hours: Shortening the DHCP lease time means that IP addresses are released and become available for reassignment more frequently. This prevents IP addresses from being tied up for extended periods when devices are not actively connected. A shorter lease time can help ensure that the IP address pool is better utilized and available for tenants' devices.
