|
A. |
use a gatekeeper to control allocated bandwidth properly |
|
B. |
use locations CAC with a single location |
|
C. |
use a gatekeeper and Cisco Unified Border Element to provide CAC to sites that use a combination of SIP and MGCP gateways |
|
D. |

QUESTION 189
Which two qualities of PKI key exchange overcome asymmetric cryptography scalability issues? (Choose two.)
|
A. |
the trusted introducer uses the signed certificates of the endpoints that need to communicate |
|
B. |
the introducer digitally signs the public key of the user with the public key of the introducer to generate a signed certificate |
|
C. |
only the public key of the introducer has to be initially known and verified by all other entities |
|
D. |
pki uses only a single trusted introducer |
Correct Answer: CD
Explanation:
Chapter 14: Understanding Cryptographic Fundamentals and PKI pg. 374 A PKI does not eliminate the need for authenticity when you exchange public keys in an asymmetric encryption environment, but it solves the scalability issues associated with that process.
A PKI uses the concept of a single, trusted introducer. Instead of securely exchanging all public keys among all devices, only the public key of the trusted introducer has to be securely distributed to all devices. This exchange is usually done by downloading the public key and then verifying it out of band.
