問題 #273
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. Increase the access point density to create an average inter-access point distance of less than 40 feet or 12.2 meters
  • B. Use directional antennas to provide more cell overlapping
  • C. Install additional access points in monitor mode where the co-channel interference would otherwise be affected
  • D. Add access points along the perimeter of the coverage area.
  • E. Fine tune the radio configuration of the access point to have a higher average transmission power to achieve better coverage

答案：C,D


問題 #274
Which Interconnectivity method offers the fastest convergence in the event of a unidirectional issue between three Layer 3 switches connected together with routed links in the same rack in a data center?

  • A. Copper Ethernet connectivity with BFD enabled
  • B. Fiber Ethernet connectivity with UDLD enabled
  • C. Fiber Ethernet connectivity with BFD enabled
  • D. Copper Ethernet connectivity with UDLD enabled

答案：C

解題說明：
* BFD (Bidirectional Forwarding Detection) provides sub-second failure detection at the control plane level, making it the fastest convergence mechanism for Layer 3 routing protocols.
* Fiber Ethernet typically offers higher reliability and lower latency than copper.
* When combined, Fiber with BFD provides the most robust and quickest convergence for unidirectional failures in a routed data center environment.
Why other options are incorrect:
* A & B: Copper adds more physical susceptibility to errors.
* B & D: UDLD is a Layer 2 unidirectional detection mechanism, not optimized for Layer 3 convergence.

問題 #275
Refer to the exhibit.

The network 10.10.0.0/16 has been redistributed to OSPF processes and the best path to the destination from R1 has been chosen as R1-R2-R3. A failure occurred on the link between R2 and R3 and the path was changed to R1-R4-R5-R3. What happens when the link between R2 and R3 is restored?

  • A. The path R1-R4-R5-R3 continues to be the best path because OSPF does not compare the metrics between two domains
  • B. The path R1-R4-R5-R3 continues to be the best path because the metric is better
  • C. The path reverts to R1-R2-R3 because this was the previous best path
  • D. The path reverts back to R1-R2-R3 because the route type is E1

答案：D

解題說明：
In the topology shown, the 10.10.0.0/16 network is redistributed into two different OSPF processes-OSPF 1 and OSPF 2-from router R3. The redistribution uses the external route types:
* Into OSPF 1 as an E1 route with a metric of 100
* Into OSPF 2 as an E2 route with a metric of 100
When redistribution occurs in OSPF, two types of external routes can be injected:
* Type E1: Adds the internal OSPF cost to the external cost (total path cost = external metric + internal OSPF path)
* Type E2: Considers only the external cost and ignores internal path cost (default behavior) In this case:
* The path via R2-R3 (E1) includes both the external cost and the internal cost from R1 to R2 to R3. That is: 10 (R1-R2) + 10 (R2-R3) + 100 (external) = 120.
* The path via R4-R5-R3 (E2) will show a constant metric of 100 regardless of the internal OSPF path (10 + 10 = ignored).
So when the link between R2 and R3 fails, the path R1-R4-R5-R3 (E2 route with constant metric 100) becomes the preferred route.
However, when the link between R2 and R3 is restored, the E1 route will be recalculated as:
* Internal cost (R1-R2-R3) = 10 + 10 = 20
* External metric = 100
* Total = 120
OSPF always prefers E1 routes over E2 routes when both are available, even if the E2 route appears to have a better metric. This is because E1 routes provide more accurate end-to-end cost calculation.
Therefore, upon restoration, the routing table reverts to the E1 route via R1-R2-R3.
This behavior is aligned with OSPF protocol standards and is emphasized in CCDE v3.1 under the "Protocol Design Implications" domain, which focuses on redistribution behaviors, route-type preferences, and convergence consistency in multi-domain IGP designs.


問題 #276
Company XYZ wants to redesign the Layer 2 part of their network and wants to use all available uplinks for increased performance. They also want to have end host reachability supporting conversational learning.
However, due to design constraints, they cannot implement port-channel on the uplinks. Which other technique can be used to make sure the uplinks are in active/active state?

  • A. switch stack
  • B. LISP
  • C. MSTP
  • D. TRILL

答案：B


問題 #277
A Tier-3 Service Provider is evolving into a Tier-2 Service Provider due to the amount of Enterprise business it is receiving. The network engineers are re-evaluating their IP/MPLS design considerations in order to support duplicate/overlapping IP addressing from their Enterprise customers within each Layer3 VPN. Which concept would need to be reviewed to ensure stability in their network?

  • A. Assigning unique IP address space for the Enterprise NAT/Firewalls
  • B. Assigning unique Route Distinguishers
  • C. Assigning unique VRF IDs to each L3VPN
  • D. Assigning unique Route Target IDs

答案：B

解題說明：
Route Distinguishers (RDs) are fundamental to MPLS Layer 3 VPN architecture (RFC 4364). They allow the service provider to distinguish identical IP prefixes from different VPN customers by adding a unique identifier to each VPN route, preventing conflicts from overlapping IP spaces.
* Unique RDs ensure that the VPNv4 address family maintains separation of identical customer prefixes.
Why other options are incorrect:
* B: Route Targets control route import/export policy but do not differentiate overlapping prefixes.
* C: NAT is not required inside MPLS VPN for overlapping IPs.
* D: VRF IDs are local identifiers on routers; not relevant for prefix uniqueness in control plane.
