Troubleshooting Intermittent Network Outages

A network administrator gets a call regarding intermittent network outages across the country.

Which of the following should be used to connect to the network so the administrator can troubleshoot this issue from home? (Choose two.)

A.

FTP

B.

SMTP

C.

VPN

D.

SSH

E.

SNMP.

CD.

The correct answers are C. VPN and D. SSH.

Explanation: To troubleshoot the network issue from home, the network administrator needs to remotely connect to the network. The two best options for remote connectivity are VPN and SSH.

VPN (Virtual Private Network) is a secure and encrypted network connection that allows remote users to securely access the corporate network over the public Internet. By using VPN, the administrator can connect to the network as if they were physically present in the office. This allows them to troubleshoot network outages across the country from their home.

SSH (Secure Shell) is a secure network protocol that allows remote access to network devices. SSH provides encrypted communication between the client and server and allows the administrator to securely access network devices remotely. SSH can be used to remotely log in to servers, routers, switches, and other network devices to troubleshoot network issues.

FTP (File Transfer Protocol) is a protocol used to transfer files between a client and a server. FTP is not a secure protocol and should not be used for remote connectivity.

SMTP (Simple Mail Transfer Protocol) is a protocol used for email transmission. SMTP is not a secure protocol and should not be used for remote connectivity.

SNMP (Simple Network Management Protocol) is a protocol used to manage and monitor network devices. SNMP is not a remote access protocol and should not be used for remote connectivity.

In summary, VPN and SSH are the best options for remotely connecting to the network to troubleshoot network outages.
