What are the two mandatory parameters that must be specified when configuring a GRE tunnel interface on Junos?

Source and destination addresses

What is the role of the Flags field in the GRE header?

It carries the payload's protocol type

It specifies the version of the GRE protocol being used

It indicates whether optional fields such as Checksum, Key, or Sequence Number are present

It contains the source and destination IP addresses of the tunnel endpoints

Which of the following payload protocols can be carried inside a GRE tunnel?

IPv4, IPv6, and other network-layer protocols

You are troubleshooting a GRE tunnel that is not passing traffic. You capture packets on the physical interface and see GRE packets being sent, but the remote router is not responding. You notice that the packets are being sent with a protocol number of 47. What does this indicate?

The packets are being sent with the wrong source IP address.

The packets are correctly identified as GRE by the IP protocol field.

The packets are being sent with the wrong protocol number and will be dropped.

The packets are being sent over TCP, which is incorrect for GRE.

What is a common issue that can cause packet fragmentation in GRE tunnels?

The tunnel uses too many keepalives

The tunnel interface has too high a bandwidth

The GRE header adds overhead, reducing the effective MTU

Generic Routing Encapsulation (GRE) JN0-364 Practice Questions (Page 1)

Part of the Tunnels domain, which makes up ~4% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~1–2 in this domain), expect 1–1 from this objective — we provide 19 practice questions to prepare you well beyond it.
