• Question 133:

  A network security technician is designing a solution for a secure remote access scheme with the following requirements:

  1.

  The solution must allow for users at multiple locations to access corporate resources.

  2.

  The on-premises equipment will not handle non-corporate, resource-bound traffic.

  Which of the following should the network security technician consider when designing the solution? (Choose two.)

  A. Clientless VPN

  B. Personal VPN

  C. Full-tunnel VPN

  D. Client-to-site VPN

  E. Site-to-site VPN

  F. Split-tunnel VPN

  Correct Answer: AF

• Question 134:

  Which of the following uses an automated script to make configuration changes when interacting with a web application?

  A. SSH

  B. FTP

  C. API

  D. GUI

  Correct Answer: C

• Question 135:

  Which of the following ports is used for secure email?

  A. 25

  B. 110

  C. 143

  D. 587

  Correct Answer: D

  Port 587 is typically used for secure email submission, specifically for sending emails securely using the SMTP (Simple Mail Transfer Protocol) with TLS (Transport Layer Security) or SSL (Secure Sockets Layer) encryption. It's commonly used as an alternative to port 25 for secure mail submission by mail clients or applications.

• Question 136:

  A network administrator wants to install new VoIP switches in small network closet but is concerned about the current heat level of the room. Which of the following should the administrator take into consideration before installing the new equipment?

  A. The power load of the switches

  B. The humidity in the room

  C. The fire suppression system

  D. The direction of airflow within the switches

  Correct Answer: D

• Question 137:

  Which of the following is the next step to take after successfully testing a root cause theory?

  A. Determine resolution steps.

  B. Duplicate the problem in a lab.

  C. Present the theory for approval.

  D. Implement the solution to the problem.

  Correct Answer: A

  Once a root cause theory has been tested and verified, the next step is to devise a plan for resolving the identified issue or problem. This involves determining the specific steps or actions necessary to implement a solution based on the validated theory. It precedes the actual implementation of the solution to address the problem effectively and prevent its recurrence.

• Question 138:

  A network administrator is configuring a new switch and wants to ensure that only assigned devices can connect to the switch. Which of the following should the administrator do?

  A. Configure ACLs.

  B. Implement a captive portal.

  C. Enable port security.

  D. Disable unnecessary services.

  Correct Answer: C

  Port security is a feature available on network switches that allows the administrator to control which devices are permitted to connect to individual switch ports. It enables the switch to limit and identify the MAC addresses allowed to access the network through specific switch ports.

  By configuring port security, the administrator can define and restrict the number of MAC addresses allowed on a port, specify which MAC addresses are permitted to access the port, and take actions (like shutting down the port) when unauthorized devices attempt to connect. This helps to prevent unauthorized devices from gaining network access via that switch port.

• Question 139:

  Which of the following does OSPF use to communicate routing updates?

  A. Unicast

  B. Anycast

  C. Multicast

  D. Broadcast

  Correct Answer: C

  OSPF uses multicast addresses to communicate routing updates. It sends its updates using the multicast address 224.0.0.5, which is used for all OSPF routers, and the multicast address 224.0.0.6, used for all OSPF designated routers. This method is efficient in terms of network bandwidth, as it allows OSPF routers to receive updates without the need for sending individual updates to each router (unicast) or broadcasting to all devices in the network (broadcast).

• Question 140:

  A user notifies a network administrator about losing access to a remote file server. The network administrator is able to ping the server and verifies the current firewall rules do not block access to the network fileshare. Which of the following tools would help identify which ports are open on the remote file server?

  A. dig

  B. nmap

  C. tracert

  D. nslookup

  Correct Answer: B

  Nmap (Network Mapper) is a powerful network scanning and reconnaissance tool used to discover hosts and services on a network. It can be used to determine what ports are open and what services are running on those ports on the remote file server. This would help in identifying any accessible services or potential issues with specific ports that might be causing the loss of access.
