A network engineer must configure the cabling between a Cisco Secure Firewall Threat Defense appliance and a network so the Secure Firewall Threat Defense appliance performs inline to analyze and tune generated intrusion events before going live. Which Secure Firewall Threat Defense mode must the engineer use?
Answer(s): D
Tap mode (Inline Pair in Tap mode) allows the Cisco Secure Firewall Threat Defense appliance to be physically inline while still operating logically in passive mode, enabling the engineer to analyze and tune intrusion events without affecting live traffic. This is ideal for pre-deployment validation.
Refer to the exhibit. An engineer is configuring an instance of Cisco Secure Firewall Threat Defense with aSecure Firewall Threat Defense interface in IPS Inline Pair mode. What must the engineer configure on interface e1/6?
Answer(s): B
When configuring an Inline Pair mode as shown in the diagram (e1/6 as INSIDE and e1/8 as OUTSIDE), "propagate link state" must be disabled on the interfaces. This ensures that if one link goes down, the other interface doesn't go down as well, which is important during intrusion prevention testing or tuning.
DRAG DROPAn engineer must configure high availability on two Cisco Secure Firewall Threat Defense appliances. Drag and drop the configuration steps from the left into the sequence on the right.Select and Place:
Answer(s): A
An engineer is setting up two new Cisco Secure Firewall Threat Defense appliances as a high-availability pair.The company needs the high-availability pair to detect a failure on the failover link and trigger a failover faster. Which two settings must the engineer decrease? (Choose two.)
Answer(s): A,C
To speed up failover detection in a Cisco Secure Firewall Threat Defense high-availability pair, you decrease:Peer poll time: how frequently a unit checks the peer's health.Peer hold time: how long it waits without receiving a response before declaring the peer failed.Reducing both leads to faster failover detection and switchover.
What is the purpose of the IRB feature in next-generation firewall?
Integrated Routing and Bridging (IRB) allows a next-generation firewall to bridge traffic between Layer 2 interfaces while also supporting routing between VLANs or subnets. This feature is commonly used in transparent (bridge) mode deployments where you want the firewall to act like a bump in the wire, forwarding traffic at Layer 2 but still providing inspection and policy enforcement.
