NEW QUESTION: 2
MACsec, which is defined in 802.1AE, provides MAC-layer encryption over wired networks. Which two statements about MACsec are true? (Choose two.)
A. MACsec manages the encryption keys that the MKA protocol uses.
B. Only links between network access devices and endpoint devices can be secured by using MACsec.
C. MACsec is designed to support communications between network devices only.
D. A switch that uses MACsec accepts either MACsec or non-MACsec frames, depending on the policy that is associated with the client.
Answer: B,D
Explanation:
MACsec, defined in 802.1AE, provides MAC-layer encryption over wired networks by using out-of-band methods for encryption keying. The MACsec Key Agreement (MKA) Protocol provides the required session keys and manages the required encryption keys. MKA and MACsec are implemented after successful authentication using the 802.1x Extensible Authentication Protocol (EAP) framework. Only host facing links (links between network access devices and endpoint devices such as a PC or IP phone) can be secured using MACsec.
A switch using MACsec accepts either MACsec or non-MACsec frames, depending on the policy associated with the client. MACsec frames are encrypted and protected with an integrity check value (ICV). When the switch receives frames from the client, it decrypts them and calculates the correct ICV by using session keys provided by MKA. The switch compares that ICV to the ICV within the frame. If they are not identical, the frame is dropped. The switch also encrypts and adds an ICV to any frames sent over the secured port (the access point used to provide the secure MAC service to a client) using the current session key.

A. Excessive levels of folic acid might accumulate, causing toxicity.
B. Erythropoiesis is inhibited.
C. The symptoms of pernicious anemia might be masked, delaying treatment.
D. Intrinsic factor is destroyed.
Answer: C

The nature of the anemia must be confirmed to ensure that the proper drug regimen is being used.Physiological Adaptation
