-
A.
-
B.
-
C.
-
D.
Answer : B
Question 14
Refer to the exhibit.
An engineer is setting up a new WLC in a branch office. The IT security policy states that all management access must use encrypted protocols, administrators will connect remotely, and network scans will be run to check for any noncompliant management protocol exposure.
Which action must the engineer take to achieve the required management access policy?
- A. Permit only HTTP, Telnet, and SSH across all VLANs for 10.10.1.0/24.
- B. Enable Telnet, SSH, and HTTPS across the management and guest interfaces.
- C. Permit console access for 10.10.1.0/24 only with HTTP disabled.
- D. Enable HTTPS and SSH, and disable HTTP and Telnet on the WLC.
Answer : D
Question 15
Refer to the exhibit.
