   A network administrator is getting reports of some internal users who cannot connect to network resources. The users state they were able to connect last week, but not today. No changes have been configured on the network devices or server during the last few weeks. Which of the following is the MOST likely cause of the issue?

   • AThe client DHCP scope is fully utilized.
   • BThe wired network is experiencing electrical interference.
   • CThe captive portal is down and needs to be restarted.
   • DSNMP traps are being received.
   • EThe packet counter on the router interface is high.

   Show answer

   Answer: A

   Explanation

   Answer A is the most likely cause of the issue because if the DHCP scope is fully utilized, it means there are no more available IP addresses for new devices to receive and connect to the network. This could prevent internal users from connecting to network resources. B. The wired network experiencing electrical interference is a possible issue but is unlikely the main cause in this scenario as it only affects wired connections. C. The captive portal being down may prevent users from accessing the Internet, but it would not prevent them from connecting to internal network resources. D. SNMP traps being received may indicate network activity, but it would not prevent users from connecting to network resources. E. A high packet counter on the router interface may indicate network activity, but it would not prevent users from connecting to network resources.

2. Question 252 · 871 in bank

   A network administrator needs to provide evidence to confirm that recent network outages were caused by increased traffic generated by a recently released application. Which of the following actions will BEST support the administrator's response?

   • AGenerate a network baseline report for comparison.
   • BExport the firewall traffic logs.
   • CCollect the router's NetFlow data.
   • DPlot interface statistics for dropped packets.

   Show answer

   Answer: C

   Explanation

   C. Collect the router's NetFlow data will BEST support the administrator's response to confirm that recent network outages were caused by increased traffic generated by a recently released application. NetFlow is a network protocol that provides detailed information about network traffic flows. By collecting NetFlow data on the router, the administrator can analyze the traffic patterns and determine if the increased traffic generated by the new application is the root cause of the network outages.

   Which of the following must be functioning properly in order for a network administrator to create an accurate timeline during a troubleshooting process?

   • ANTP
   • BIP helper
   • CSyslog
   • DMySQL

   Show answer

   Answer: A

   Explanation

   The function that must be functioning properly in order for a network administrator to create an accurate timeline during a troubleshooting process is A. NTP (Network Time Protocol). NTP is a networking protocol that is used to synchronize the clocks of network devices to a reference time source. An accurate and synchronized clock is essential for creating an accurate timeline during a troubleshooting process. If the clocks of network devices are not synchronized, it can be difficult to correlate events and identify the sequence of events that led to a network issue. The other options, B. IP helper, C. Syslog, and D. MySQL, are not directly related to creating an accurate timeline during a troubleshooting process. IP helper is used to forward DHCP and other broadcast traffic between subnets, Syslog is used for event logging and monitoring, and MySQL is a database This jake guy just giving wrong answers be carefull, admin should do something

7. Question 257 · 871 in bank

   An IT director is setting up new disaster and HA policies for a company. Limited downtime is critical to operations. To meet corporate requirements, the director set up two different datacenters across the country that will stay current on data and applications. In the event of an outage, the company can immediately switch from one datacenter to another. Which of the following does this BEST describe?

   • AA warm site
   • BData mirroring
   • CMultipathing
   • DLoad balancing
   • EA hot site

   Show answer

   Answer: E

   Explanation

   A hot site is a leased facility that contains all the resources needed for full operation. This environment includes computers, raised flooring, full utilities, electrical and communications wiring, networking equipment, and uninterruptible power supplies (UPSs). The only resource that must be restored at a hot site is the organization’s data, usually only partially. It should only take a few minutes to bring a hot site to full operation. Although a hot site provides the quickest recovery, it is the most expensive to maintain. In addition, it can be administratively hard to manage if the organization requires proprietary hardware or software. A hot site requires the same security controls as the primary facility and full redundancy, including hardware, software, and communication wiring.

10. Question 260 · 871 in bank

    A network client is trying to connect to the wrong TCP port. Which of the following responses would the client MOST likely receive?

    • ARST
    • BFIN
    • CICMP Time Exceeded
    • DRedirect

    Show answer

    Answer: A

    Explanation

    A. RST (Reset) is the most likely response that the client would receive if it is trying to connect to the wrong TCP port. TCP (Transmission Control Protocol) is a connection-oriented protocol, which means that a connection needs to be established between the client and the server before data can be exchanged. During the connection establishment process, the client sends a SYN (Synchronize) packet to the server, and the server responds with a SYN-ACK (Synchronize-Acknowledge) packet. If the client is trying to connect to the wrong TCP port, the server will not respond with a SYN-ACK packet, and instead, it will send a RST packet to terminate the connection attempt.
