You are implementing a new route-based IPsec VPN on an SRX Series device and the
tunnel will not establish.
What needs to be modified in the configuration shown in the exhibit?

You have created an IPsec VPN on an SRX Series device. You believe the tunnel is
configured correctly, but traffic from a host with the IP address of 10.12.1.10 cannot reach a
remote device over the tunnel with an IP address of 10.128.64.132. The ge-0/0/1.0 interface
is in the trust zone and the st0.0 interface is in the vpn zone. The output of four show
commands is shown in the exhibit.
What is the configuration problem with the tunnel?

The exhibit shows output from two show commands.
What are two conclusions about the VPN tunnel from the output? (Choose two.)

Click the Exhibit button.
Server A is communicating with Server B directly over the Internet. The servers now must
begin exchanging additional information through an unencrypted protocol. To protect this
new data exchange, you want to establish a VPN tunnel between the two sites that will
encrypt just the unencrypted data while leaving the existing communications directly over the
Internet.
Which statement would achieve the desired results?

Click the Exhibit button.
Referring to the exhibit, you have built a chassis cluster, set up a reth, and put interfaces into
the reth. However, when you try to commit the configuration, you receive the error shown in
the exhibit.
Which configuration command will correct this error?

Click the Exhibit button.
Referring to the exhibit, failover to Node 0 occurred for Redundancy Group 2 because of an
interface failure. The interface has since been restored, but Node 0 is still the primary node
for Redundancy Group 2.
Which two actions will restore Node 1 as the primary node for Redundancy Group 2?
(Choose two.)

Referring to the exhibit, you have two SRX Series devices in a chassis cluster, and Node 0
is currently the primary node. You want to ensure that traffic using those interfaces fails over
to Node 1 if one interface goes down.
Which configuration change should be made to ensure failover to Node 1?

Referring to the exhibit, you have two SRX Series devices in a chassis cluster, and Node 0
is currently the primary node. You want to ensure that traffic, using those interfaces, fails
over to Node 1 when all interfaces go down.
Which configuration change should be made to ensure failover to Node 1?

Click the Exhibit button.
Referring to the exhibit, with Node 0 as primary for Redundancy Group (RG) 1, which action
will the Junos OS chassis cluster take if interface ge-1/0/0 goes down?

Click the Exhibit button.
You have configured antispam on your SRX Series device as shown in the exhibit.
Assuming the antispam profile has been properly applied, what happens when an e-mail
message arrives at the SRX device from bob@domain-xyz.net at IP address 150.10.10.10?
