What protocols are used in remote access?
The primary remote access protocols in use today are the Serial Line Internet Protocol (SLIP), Point-to-Point Protocol (PPP), Point-to-Point Protocol over Ethernet (PPPoE), Point-to-Point Tunneling Protocol (PPTP), Remote Access Services (RAS), and Remote Desktop Protocol (RDP).
What protocol is used when connecting remotely to a Cisco router?

What is the difference between HTTPS and SSH?
Any time someone uses a website with a URL that starts with HTTPS, he is on a site with SSL/TLS. SSH is for securely executing commands on a server. SSL is used for securely communicating personal information. SSH uses a username/password authentication system to establish a secure connection.
Who is more secure protocol for remote login?
While Remote Desktop is more secure than remote administration tools such as VNC that do not encrypt the entire session, any time Administrator access to a system is granted remotely there are risks. The following tips will help to secure Remote Desktop access to both desktops and servers that you support.
What are Switching protocols?
101 Switching Protocols is a status code that's used for a server to indicate that the TCP conncection is about to be used for a different protocol. The best example of this is in the WebSocket protocol. WebSocket uses a HTTP handshake when creating the connection, mainly for security reasons.
How many protocols are there in CCNA?
Two main types of routing protocols exist - distance vector and link state.
What are the three routing protocols?
Routing protocols are mechansims by which routing information is exchanged between routers so that routing decisions can be made. In the Internet, there are three types of routing protocols commonly used. They are: distance vector, link state, and path vector.
Which protocol is not supported by Cisco anymore?
End of Life for TLS 1.0/1.1. As of March 31, 2020**, Transport Layer Security (TLS) 1.0 and 1.1 will no longer be supported by Cisco Umbrella servers and services.
Which interface connects to external networks usually over a large distance?
Serial WAN interfacesSerial WAN interfaces - Used for connecting routers to external networks, usually over a larger geographical distance.
Which three types of traffic is the router service plane responsible for processing?
In general, routers handle transit, receive, and exception packets in different ways. As you may imagine, routers are optimized to process transit traffic with the most efficiency and speed.
How do switches and routers work in a network?
Just as a switch connects multiple devices to create a network, a router connects multiple switches, and their respective networks, to form an even larger network. These networks may be in a single location or across multiple locations.

What is VTY Access?
An efficient way to manage remote devices is to use VTY access, which is CLI-based remote access using Telnet or SSH.
Can Cisco routers use SSH?
Cisco routers and Catalyst switches can also provide VTY access to other devices as an SSH client. use the following commands in user EXEC or privileged EXEC mode to remotely log in to other devices as an SSH client.
Can you enable SSH on VTY?
