Answer: BD
2. Which definition best describes the implementation service component within the implement phase?
A. providing a step-by-step plan that details the installation and service-commission tasks required in order to create a controlled-implementation environment that emulates a customer network
B. assessing the ability of site facilities to accommodate proposed infrastructure changes
C. developing and executing proof-of-concept tests, validating high-level infrastructure design, and identifying any design enhancements
D. installing, configuring, and integrating systems components based on an implementation plan developed in earlier phases
E. improving a customer's infrastructure security system
Answer: D
3. What two types of telephony interfaces are used for PSTN connectivity? (Choose two.)
A. Digital
B. Optical
C. Analog
D. CDMA
Answer: AC
4. Which benefit can be obtained by using the change management service component in the operate phase?
A. reduced operating costs, due to a consistent framework for making necessary changes in an efficient and accountable manner
B. greater accuracy, completeness, and timeliness of network configuration information
C. notification provided to interested parties regarding problems that have been identified, and a system that scales with customer requirements
D. improved system service quality and fewer disruptions
Answer: A
5. Refer to the exhibit. Switches A and C are running PVST+ STP, and Switch B is running 802.1Q STP. If the BPDU of the root in VLAN 1 is better than the BPDU of the root in VLAN 2, then there is no blocking port in the VLAN 2 topology. The BPDU of VLAN 2 never makes a "full circle" around the topology; it is replaced by the VLAN 1 BPDU on the B-C link, because B runs only one STP merged with VLAN 1 STP of PVST+. Thus, there is a forwarding loop.
What does PVST+ do to correct this?
A. Switch A sends PVST+ BPDUs of VLAN 2 (to the SSTP address that is flooded by Switch B) towards Switch C. Switch C will put port C-B into a type-inconsistent state, which prevents the loop.
B. Switch B sends PVST+ BPDUs of VLAN 1 (to the SSTP address that is flooded by Switch A) towards Switch C. Switch C will put port C-B into a type-inconsistent state, which prevents the loop.
C. Switch C sends PVST+ BPDUs of VLAN 2 (to the SSTP address that is flooded by Switch B) towards Switch C. Switch A will put port C-B into a type-inconsistent state, which prevents the loop.
D. Switch A sends PVST+ BPDUs of VLAN 1 (to the SSTP address that is flooded by Switch B) towards Switch B. Switch A will put port C-B into a type-inconsistent state, which prevents the loop.
Answer: A
