Correct

Incorrect
Question 5 of 8

5. Question
Fill in the blank.
- Virtual Switching Framework (VSF) lets two switches function as a single virtual switch called a VSF fabric.
Correct

Incorrect
Question 6 of 8

6. Question
Fill in the blank.
- VSF fabric looks like a modular switch that has been extended over two chassis, where all switches have:
  - A plane, which provides administrators and management solutions access to management interfaces such as the command line interface (CLI)
  - A plane, which runs protocols and builds routing and MAC forwarding tables
  - A plane, which processes and forwards packets
Correct

Incorrect
Question 7 of 8

7. Question
Which of the following statements best describes VXLAN?
- 1. A technology which allows overlaying a Layer 2 (L2) network over a Layer 3 (L3) underlay with use of any IP routing protocol.
- 2. One logical/virtual switch is distributed physically in two chassis, and two switches can be managed as a single entity.
- 3. Virtual devices eliminate a single point of failure (SPOF) while simplifying router redundancy using a single IP address rather than complex router redundancy protocols.
- 4. Virtualizes the control plane of two aggregation switches to function as one device at Layer 2 and as independent devices at Layer 3
Correct

Incorrect
