Which two types of tunnels are able to be created on all Junos devices? (Choose two.)

Show Suggested Answer Hide Answer
Suggested Answer: B, D

Junos devices support various types of tunnels for different purposes12.

Option B is correct.Generic Routing Encapsulation (GRE) is a tunneling protocol that can encapsulate a wide variety of network layer protocols inside virtual point-to-point links over an Internet Protocol network1.Junos devices support GRE tunnels1.

Option D is correct.IPsec (Internet Protocol Security) is a protocol suite for securing Internet Protocol (IP) communications by authenticating and encrypting each IP packet of a communication session1.Junos devices support IPsec tunnels1.

Option A is incorrect. Spanning Tree Protocol (STP) is not a type of tunnel.It's a network protocol designed to prevent loops in a bridged Ethernet local area network2.

Option C is incorrect.While Junos devices do support IP-IP (also known as IP tunneling), it's not supported on all Junos devices1.

I remember practicing a question like this, and I think GRE is definitely one of the answers. Not sure about the second one though.

I'm a little confused on this one. I know Junos has support for various tunneling technologies, but I'm not sure which ones are available on all Junos devices. I'll have to review my notes to refresh my memory.

Okay, let me think this through step-by-step. GRE and IP-IP tunnels are common on Junos, so those are likely the two correct answers. I'll double-check the options to confirm.

Hmm, I'm a bit unsure about this one. I know Junos supports some tunneling protocols, but I can't recall which ones off the top of my head. I'll have to think this through carefully.

I'm a little confused by the getter function syntax here. Is it possible to access the fullName property directly, or do we need to call it as a method? I'll have to review my notes on object getters and setters.

All of the above, obviously. Junos can do anything, including turning your router into a time machine. Now, where did I put that flux capacitor?

B and D, no doubt. GRE and IPsec are the bread and butter of Junos tunneling. I'd be shocked if they couldn't do those on any device.
