QUESTION 132

Which of the following statements regarding the IDS Sensor communications is valid?

A. RDEP makes use of SSL for secured internal communications.

B. RDEP makes use of SSH for secure external communications.

C. PostOffice protocol makes use of IPSec for secured external communications.

D. IDAPI makes use of HTTPS for secured internal communications.

E. cidCU makes use of SSH for secured external communications.

Answer: A

RDEP uses HTTP and TLS/SSL to securely pass XML documents.

Cisco Courseware 4-35

RDEP mismatches the keyword "internal", but SSH (B) is definitely incorrect.

As REDP is even used to communicate between Sensors (Blocking Forwarding Sensor to Blocking Master

Sensor), perhaps "internal" matches Cisco's definition?

QUESTION 133

Which of the following statements regarding the Master Blocking Sensor communications is valid? (Choose

three.)

A. A Master Blocking Sensor can use Telnet to communicate with a PIX Firewall.

B. A Blocking Forwarding Sensor uses SSH to communicate with a Master Blocking Sensor.

C. An IDS v4.0 Sensor can server as a Master Blocking Sensor for IDS v3.x and IDS v4.0 Sensors.

D. A Master Blocking Sensor can communicate block requests to another Master Blocking Sensor.

E. A Blocking Forwarding Sensor can communicate block requests to another Blocking Forwarding Sensor.

F. A Master Blocking Sensor uses RDEP to communicate with a Blocking Forwarding Sensor.

Answer: A D, F

A: Cisco Courseware 15-7

D: Cisco Courseware 15-31

F: Although the direction "Master to Forwarding" is a little confused.

NOT B: Cisco Courseware 15-30: RDEP is used to communicate between Sensors, and

RDEP uses SSL, not SSH!

NOT C: 4.0 Sensors only support RDEP, 3.x Sensors only PostOffice -> They can't

communicate.

NOT E: Blocking Forwarding Sensors can only communicate to Masters.

QUESTION 134

You are the Certkiller administrator and have been requested to permit communications with a Blocking

Forward Sensor using encryption. Which of the following will you configure on the Master Blocking Sensor in

order to accomplish communications as requested?
