QUESTION 1
How would you define a fault tolerant device?
A. A backup path exists for every link between the client and the server.
B. Key components can be hot-swapped.
C. A backup device exists for every device between the client and the server.
D. Devices in the network can be hot-swapped without interrupting the network operation.
E. The device provides redundant backup within the device for each of its key components.
Correct Answer: E Section: (none) Explanation
Explanation/Reference: Explanation:
Device fault tolerance and redundancy: This is often the first level of availability in the network. Fault-tolerant devices provide a high level of reliability. Cisco offers options for redundant supervisor engines and dual power supplies, which provide the first backstop against a network failure.
Reference: Arch student guide p.1-13.

QUESTION 3
Which of the following metrics are used to measure performance in the Enterprise Edge module of the Enterprise Composite Network model? (Select three.)
A. Grade of service
B. Response time
C. Throughput
D. Transmit jitter
E. Utilization
Correct Answer: BCE Section: (none) Explanation
Explanation/Reference: Explanation:
Performance might be the least understood term in networking. Typically, performance is defined as
throughput and packets per second (pps). These are easy numbers to gauge and report, but these values
relate to a single switch or router and make no sense when measuring an entire network.
The point is that there is no one metric for determining performance. Instead, gauge network performance
by these three metrics:
1) Responsiveness.
2) Throughput.
3) Utilization.
Reference: Arch student guide p. 1-10.
QUESTION 4
Which of the following is considered part of a Fault Tolerant Device? (Choose three)

Correct Answer: ABC Section: (none) Explanation
Explanation/Reference: Explanation:
This is often the first level of availability in the network. Fault-tolerant devices provide a high level of reliability. Cisco offers options for redundant supervisor engines and dual power supplies, which provide the first backstop against a network failure.
Reference: Arch student guide p.1-13
