Question

what are three ways that media access control is used in networking? (choose three.) 802.11 utilizes csma/cd. media access control provides placement of data frames onto the media. contention - based access is also known as deterministic. ethernet utilizes csma/cd. networks with controlled access have reduced performance due to data collisions. data link layer protocols define the rules for access to different media.

Explanation:

1. 802.11 uses CSMA/CA, not CSMA/CD, so the first option is incorrect.
2. Media access control indeed places data frames onto the media.
3. Contention - based access is random, not deterministic.
4. Ethernet uses CSMA/CD for media access control.
5. Networks with controlled access reduce data collisions and improve performance, not reduce performance due to collisions.
6. Data link layer protocols define media access rules.

Answer:

B. Media access control provides placement of data frames onto the media.
D. Ethernet utilizes CSMA/CD.
F. Data link layer protocols define the rules for access to different media.
