You have configured static NAT for a webserver in your DMZ. Both internal and external users can reach the webserver using the webserver's IP address. However, only internal users can reach the webserver using the webserver's DNS name. When external users attempt to reach the webserver using the webserver's DNS name, an error message is received.

Which action would solve this problem?

Disable Web filtering
Use DNS doctoring
Modify the security policy
Use destination NAT instead of static NAT

You have configured three logical tunnel interfaces in a tenant system on an SRX1500 device. When committing the configuration, the commit fails.

In this scenario, what would cause this problem?

There is no GRE tunnel between the tenant system and master system allowing SSH traffic
There is no VPLS switch on the tenant system containing a peer It-0/0/0 interface
The SRX1500 device does not support more than two logical interfaces per tenant system
The SRX1500 device requires a tunnel PIC to allow for logical tunnel interfaces

Correct answer: B
