Cisco Certified Design Expert (CCDE) Written Exam 認定 400-007 試験問題 (Q366-Q371):

質問 # 366
Company XYZ has a new network based on IPv6. Some of the subnets that they are planning to use will be confidential and need an addressing scheme that confines them to the local campus network. Which type of IPv6 addresses can be used for these networks in the IPv6 addressing design?

正解：C

解説：
* D (Unique Local Addresses - ULA): IPv6 addresses in the FC00::/7 range, used for internal networks only, not routable over the global internet.
* Ideal for campus or enterprise networks requiring internal-only addressability while avoiding conflict with global prefixes.
Why other options are incorrect:
* A & B: Not valid IPv6 address types.
* C: Link-local addresses (FE80::/10) are valid only for single-hop communication and cannot be routed even within the local campus.

質問 # 367
Refer to the exhibit. A customer needs to implement a connectivity model by using one active link for inbound and outbound traffic and a second link for backup. The backup link is low speed and is required only during outages of the primary link. Which design solution should be implemented?

正解：A

解説：
To implement a primary and backup link design, a common approach is to manipulate BGP attributes such as AS PATH and MED (Multi-Exit Discriminator). By advertising a longer AS PATH to ISP 2, the primary link (ISP 1) is preferred due to its shorter AS PATH. Increasing the MED to ISP 2 also helps in making it less preferred unless the primary link fails, thereby making ISP 2 the backup link.


質問 # 368
Refer to the exhibit.

Refer to the exhibit. A new high availability DB server cluster is installed in the network. These two servers require high bandwidth and low latency Layer 2 connectivity for database replication.
Which solution supports these requirements?

正解：B

解説：
To support high-bandwidth, low-latency Layer 2 communication between DB Server 1 and DB Server 2, you must create a direct Layer 2 path between SW1 and SW2. Using REP (Resilient Ethernet Protocol) segments ensures loop-free Layer 2 operation without the drawbacks of STP convergence delays.
* Option C is correct: Adding a third REP segment (Segment 3) directly between SW1 and SW2 isolates the traffic between the two DB servers and ensures deterministic behavior with fast convergence.
* Option A (LACP with STP) introduces STP blocking and doesn't align well with REP's control plane.
* Option B and D: Overloading existing segments or splitting new links into existing REP segments does not offer the same direct path, bandwidth, or deterministic behavior.


質問 # 369
A large enterprise is planning a new WAN connection to headquarters. The current dual-homed setup with static routing is not providing consistent resiliency. Users complain when one specific link fails, while failure of the other causes no issues. The organization wants to improve resiliency and ROI.
Which solution should be recommended?

正解：D

解説：
Comprehensive and Detailed Explanation:
* C: Using dynamic routing protocols (e.g., OSPF, EIGRP, or BGP) provides real-time path selection, automatic failover, and improved resiliency. It eliminates manual reconfiguration delays associated with static routing, directly addressing user experience issues during failure.
Other options:
* A: QoS improves traffic prioritization, not failover/resiliency.
* B: Bandwidth upgrades do not address the failure-handling problem.
* D: Adding a third link increases cost without solving the root issue-ineffective routing response.


質問 # 370
Which design solution reduces the amount of IGMP state in the network?

正解：C
