• Question 445:

  Two new network switches located in different buildings are connected together with single-mode fiber. However, no link exists between the two switches. Which of the following steps should the technician perform FIRST to troubleshoot the issue?

  A. Reverse TX/RX on the fiber patch cord at one building.

  B. Replace the fiber patch cords in both buildings.

  C. Clean the fiber patch cord connectors in both buildings.

  D. Connect the fiber patch cord to an OTDR at one building.

  Correct Answer: C

  The FIRST step the technician should perform to troubleshoot the issue is C. Clean the fiber patch cord connectors in both buildings.

  Dirty or contaminated fiber patch cord connectors can cause signal loss and poor network performance, and may even prevent a link from being established. Before trying any other troubleshooting steps, it is important to ensure that the fiber patch cord connectors are clean and free of debris.

• Question 446:

  Which of the following is the MOST secure connection used to inspect and provide controlled internet access when remote employees are connected to the corporate network?

  A. Site-to-site VPN

  B. Full-tunnel VPN

  C. Split-tunnel VPN

  D. SSH

  Correct Answer: B

  The MOST secure connection used to inspect and provide controlled internet access when remote employees are connected to the corporate network is Full-tunnel VPN. In a full-tunnel VPN, all traffic from the remote user's device is routed through the VPN tunnel to the corporate network. This provides the highest level of security because all traffic is encrypted and inspected by the corporate network's security devices.

• Question 447:

  Which of the following BEST describes a split-tunnel client-to-server VPN connection?

  A. The client sends all network traffic down the VPN tunnel.

  B. The client has two different IP addresses that can be connected to a remote site from two different ISPs to ensure availability.

  C. The client sends some network traffic down the VPN tunnel and other traffic to the local gateway.

  D. The client connects to multiple remote sites at the same time.

  Correct Answer: C

• Question 448:

  An organization requires the ability to send encrypted email messages to a partner from an email server that is hosted on premises. The organization prefers to use the standard default ports when creating firewall rules. Which of the following ports should be open to satisfy the requirements?

  A. 110

  B. 143

  C. 587

  D. 636

  Correct Answer: C

  Port 587 is used for email message submission, typically by clients to an email server.
