Cisco Certified Design Expert (CCDE) Written Exam 認定 400-007 試験問題 (Q498-Q503):

質問 # 498

Refer to the exhibit. A service provider has a requirement to use Ethernet OAM to detect end-to-end connectivity failures between SP-SW1 and SP-SW2. Which two ways to design this solution are true?
(Choose two)

A. Use upward maintenance endpoints on the SP switches
B. Enable Connectivity Fault Management on the SP switches
C. Forward LLDP PDUs over the VPLS
D. Forward E-LMI PDUs over VPLS
E. Enable unicast heartbeat messages to be periodically exchanged between MEPs

正解：B、E

解説：
In service provider Ethernet transport environments such as VPLS, Ethernet OAM (Operations, Administration, and Maintenance) is used to provide fault detection, monitoring, and troubleshooting capabilities. The two relevant components here are:
A (Unicast heartbeat messages between MEPs): Maintenance End Points (MEPs) are configured at the edges of the OAM domain (SP-SW1 and SP-SW2). Heartbeat messages can be used to proactively monitor and detect loss of continuity between the endpoints.
B (Enable Connectivity Fault Management): CFM (IEEE 802.1ag) provides end-to-end fault detection, continuity check messages (CCMs), loopback, and link trace mechanisms that operate between MEPs at Layer 2. CFM enables proactive detection of failures and service-level assurance across the provider's Ethernet segment.
Other options explained:
C: Upward MEPs are not applicable here since these are typically used for customer-facing or hierarchical maintenance domains.
D: E-LMI (Ethernet Local Management Interface) operates between CE and PE for service activation-not applicable for SP-SW to SP-SW fault detection across VPLS.
E: LLDP (Link Layer Discovery Protocol) is for neighbor discovery on directly connected interfaces-not suitable for end-to-end fault detection across a VPLS domain.
This design solution aligns fully with CCDE v3.1 principles for service provider Layer 2 VPN design and Ethernet OAM integration.

質問 # 500
An existing wireless network was designed to support data traffic only.
You must now install context Aware services for location tracking changes must be applied to the existing wireless network to increase the location accuracy? (Chose two)

A. Fine tune the radio configuration of the access point to have a higher average transmission power to achieve better coverage
B. Install additional access points in monitor mode where the co-channel interference would otherwise be affected
C. Add access points along the perimeter of the coverage area.
D. Increase the access point density to create an average inter-access point distance of less than 40 feet or 12.2 meters
E. Use directional antennas to provide more cell overlapping

正解：B、C

質問 # 501
which two actions must be taken when assessing an existing wireless network implementation for its readliness to support voice traffic? (choose two)

A. Identify frequent TX power changes.
B. Check for high channel utilization
C. Verify that RX level are not above -6WBm.
D. Analyze typical roaming delays.
E. Validate antenna settings on APs

正解：C、D

質問 # 502
Company XYZ asks for design recommendations for Layer 2 redundancy. The company wants to prioritize fast convergence and resiliency elements in the design.
Which two technologies are recommended? (Choose two.)

B. Use BPDU guard.
C. Configure DHCP snooping on the switches.
D. Use root guard.
E. Design MLAG/MC-LAG into the network wherever possible.

正解：A、E
