질문 # 225 
Refer to the exhibit. An architect is designing a network that requires route redistribution. The design must prevent route feedback and the creation of routing loops. The OSPF domain is using default metrics, and the IS-IS domain is using narrow metrics. Which solution must the architect select?
정답：D
설명：
Route tagging with a route map is the correct redistribution loop-prevention method. In a design with mutual redistribution between OSPF and IS-IS, a route learned from one domain can be redistributed into the other domain and then fed back into the original domain at another redistribution point. This creates route feedback, suboptimal routing, or loops. Cisco routing design commonly prevents this by tagging routes at the point of redistribution and then filtering or denying routes with that tag when they are seen again at another redistribution boundary. A route map can set the tag during redistribution and match the tag on the reverse redistribution direction. Changing administrative distance may influence local route selection, but it does not reliably prevent feedback throughout the network. Stub areas reduce external LSA scope in OSPF, but they do not solve a multipoint redistribution loop between OSPF and IS-IS. Prefix filtering can work, but tagging scales better and preserves route identity across redistribution points. Reference topics: route redistribution, route tagging, route maps, OSPF, IS-IS, loop prevention.
질문 # 226

질문 # 227
Refer to the exhibit.
An architect is designing an EIGRP solution based on these requirements:
* Traffic forwarding should use the best two paths while all links are available
* Single path failure must not impact traffic between branch and HQ
Which solution must the architect select?
정답：B
설명：
ENSLD cert guide page 113. shortest path = 900, next 1700 and finally 3300 for the worst path. Witch variance 2, all routes under 1800 (900x2) become active.
질문 # 228
An architect is designing a network solution for a customer The network is IPv6-only with 1000 hosts. The design must provide external access to up to 10 concurrent IPv6 hosts to allow communication with legacy IPv4 devices on an adjacent network. The customer set aside 10 IPv4 addresses to allow for one-to-one communication between hosts. Which solution must the architect select?
정답：C
질문 # 229
A company requires a private WAN design that allows remote sites to connect to HQ. The design must ensure that:
* traffic is always encrypted
* forwarding overhead is reduced
* management of security Is centralized
* multicast traffic is supported
Which technology must the company select?
정답：C
설명：
GET VPN is the correct private WAN encryption technology when traffic must always be encrypted, multicast must be supported, forwarding overhead must be reduced, and security management must be centralized. Cisco Group Encrypted Transport VPN protects traffic over a private WAN without building traditional point-to-point or multipoint tunnel overlays. Because it preserves the original IP header, the provider or enterprise routing core can still make normal forwarding decisions, and multicast, QoS, and routing behavior are easier to preserve than with heavy tunnel overlays. GET VPN uses a key server model to centralize group policy and distribute encryption keys to group members. This reduces the operational burden of maintaining many permanent tunnels. DMVPN supports multicast through GRE and provides dynamic tunnels, but it adds tunnel encapsulation overhead and does not meet the reduced-overhead private WAN requirement as cleanly. Plain mGRE lacks the full centralized group encryption model. Reference topics: GET VPN, group encryption, private WAN security, multicast support, key server, tunnel-less IPsec.
