NEW QUESTION # 428
Refer to the exhibit.
An architect must design an IGP solution for an enterprise customer. The design must support:
Physical link flaps should have minimal impact.
Access routers should converge quickly after a link failure.
Which two ISIS solutions should the architect include in the design? (Choose two.)
Answer: C,D
Explanation:
The correct IS-IS design combines tuned SPF/PRC behavior with a proper Level 1 and Level 2 hierarchy.
Reducing SPF and PRC intervals, within platform and stability limits, helps routers react more quickly to topology changes after a link failure. However, fast timers alone are not enough; the hierarchy must contain instability so physical link flaps in the access layer have limited impact on the rest of the network. Access routers should form Level 1 adjacencies inside their local area, while aggregation routers should operate as Level 1/Level 2 routers to connect the access area to the Level 2 backbone. This design gives access routers a simple local view and uses aggregation as the interarea boundary. Running all access and aggregation routers as L1/L2 across the network increases the size of the backbone and exposes more routers to wider flooding, which is the opposite of the requirement. Redistributing Internet routes into Level 1 is also poor design because it bloats the access area. Therefore, the right choices are C and E. Reference topics: IS-IS hierarchy, L1/L2 design, SPF and PRC tuning, access-layer convergence, fault containment.
NEW QUESTION # 429
Company A recently acquired another company. Users of the newly acquired company must be able to access a server that exists on Company A's network, both companies use overlapping IP address ranges. Which action conserves IP address space and provides access to the server?
Answer: A
Explanation:
The best answer is to use a single IP address for a static NAT entry that represents the server with a nonoverlapping address. When two companies use overlapping private address space, routing directly between the networks can fail because each side may already have a local route for the same prefix. The requirement is narrow: users in the acquired company need access to one server in Company A, and the design must conserve address space. A static NAT mapping for the server solves the destination overlap problem with one translated address, giving remote users a unique reachable address for that server without renumbering either company. Overload NAT is normally used to translate many inside clients behind one address for outbound access; it is not the most precise solution for publishing one overlapping server. One-to- one NAT for every user wastes addresses and adds operational overhead. Readdressing the acquired company would solve the overlap permanently, but it does not conserve effort or address space. Therefore, a single static NAT entry for the server is the most efficient design.

Answer: B
NEW QUESTION # 432
An organization is designing a detailed QoS plan that limits bandwidth to specific rates. Which two parameters are supported be the traffic policing feature? (Choose two.)
Answer: C,E
Explanation:
Cisco traffic policing evaluates packets against a configured traffic contract and classifies them into action states such as conforming, exceeding, and violating. The policy then applies configured actions to those states, such as transmit, drop, or remark. In a two-rate or three-color policing design, conforming traffic is within the committed rate, exceeding traffic is above the committed rate but may still be within an excess burst allowance, and violating traffic is outside the permitted profile. Therefore, conforming and violating are valid policing parameters or state/action categories in the context of the question. Shaping is not a policing parameter; it is a different QoS mechanism that buffers excess traffic and sends it later. Marking can be an action applied by policing, but the listed policing state that directly corresponds to Cisco class-based policing syntax is conform or violate. Bursting is related to token bucket sizing, but the answer choices specifically align to policing state categories. The correct pair is violating and conforming.
