Which benefit does ADVPN provide compared to a traditional hub-and-spoke VPN?

It simplifies IPsec configuration by using a single pre-shared key for all devices

It reduces the need for a hub device entirely

It allows spokes to communicate directly without traversing the hub, reducing hub bandwidth usage

It guarantees lower latency for all traffic by always using direct paths

In an ADVPN network, what is the role of the hub device?

To act as a firewall for all spoke-to-spoke traffic

To act as a signaling point and route traffic between spokes

To encrypt all traffic between spokes

To provide a central point for tunnel signaling and route propagation

Which command is used on Junos to verify the status of ADVPN tunnels?

show security ipsec security-associations

show security dynamic-vpn tunnels

Which configuration element is required on a spoke device to enable ADVPN?

A static route to the hub's loopback address

A BGP session with all other spokes

An IPsec VPN configuration with the hub as the peer and the 'auto-discovery' option enabled

Auto Discovery VPNs (ADVPNs) JN0-637 Practice Questions (Page 3)

Part of the Advanced IPsec VPNs domain, which makes up ~20% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–12 in this domain), expect 1–2 from this objective — we provide 15 practice questions to prepare you well beyond it.
