Cisco Designing Cisco Enterprise Networks 300-420 Prüfungsfragen mit Lösungen (Q142-Q147):

142. Frage
Refer to the exhibit. The full EIGRP routing table is advertised throughout the network. Currently, users experience data loss when any one link in the network fails. An architect optimizes the network to reduce the impact when a link fails. Which solution should the architect include in the design?

A. Reduce the default EIGRP hello interval and hold time
B. Summarize the access layer networks from each access layer switch toward the aggregation layer
C. Run BFD on the inter links between EIGRP neighbors.

Antwort: C

143. Frage
Refer to the exhibit. An architect must design an IPv6 migration solution for an enterprise customer to support these requirements:
- Clients will transition to the new IPv6 network, which provides NAT64 and IPv6 DNS resolution services, using the same DNS name that points to the IPv4 address.
- The service provider will create a client-facing IPv6 interface with
a new IPv6 virtual address that points to the same IPv4 DNS server.
- The service provider will support clients that use global IPv6
addresses and encapsulate IPv4 packets into IPv6 tunnels.
Which two migration solutions must the architect choose? (Choose two.)

A. Use dual-stack lite from the devices to the core MPLS network.
B. Use IPv6 tunneling from the devices to the core MPLS network.
C. Use dual-stack lite from the MPLS network to the IGR.
D. Use NAT44/64 from the devices to the core MPLS network.
E. Use NAT44/64 from the MPLS network to the IGR.

Antwort: A,E

144. Frage

Refer to the exhibit. All routers currently reside in OSPF area 0. The network manager recently used R1 and R2 as aggregation routers for remote branch locations and R3 and R4 for aggregation routers for remote office locations. The network has since been suffering from outages, which are causing frequent SPF runs. To enhance stability and introduce areas to the OSPF network with the minimal number of ABRs possible, which two solutions should the network manager recommend? (Choose two.)

A. a new OSPF area for R3 and R4 connections,with R5 and R6as ABRs
B. a new OSPF area for R1 and R2 connections,with R1 and R2as ABRs
C. a new OSPF area for R1 and R2 connections, with R5 and R6 as ABRs
D. a new OSPF area for R1, R2, R3, and R4 connections, with R1, R2, R3, and R4 as ABRs
E. a new OSPF area for R3 and R4 connections,with R3 and R4as ABRs

Antwort: A,C

145. Frage
Which nonproprietary mechanism can be used to automate rendezvous point distribution in a large PIM domain?

A. Embedded RP
B. BSR
C. Static RP
D. Auto-RP

Antwort: B

Begründung:
The standards-based mechanism for dynamic rendezvous point distribution in a large PIM domain is Bootstrap Router. BSR allows candidate RPs and candidate BSRs to participate in a standards-based election and advertisement process so PIM routers can learn the RP set dynamically. This avoids configuring every router manually with static RP information and avoids depending on a Cisco-proprietary mechanism. Auto- RP can also distribute RP information dynamically, but Auto-RP is Cisco proprietary and therefore does not meet the nonproprietary requirement. Embedded RP is associated with IPv6 multicast group addressing and is not the general-purpose answer for automating RP discovery in a large IPv4 PIM domain. Static RP configuration is simple and deterministic, but it does not automate RP distribution and becomes operationally fragile as the multicast domain grows. In Cisco multicast design, BSR is the correct choice when the network requires dynamic RP discovery, vendor-neutral behavior, and scalable PIM-SM operation across a large domain.

146. Frage
A customer is discussing QoS requirements with a network consultant. The customer has specified that endto-end path verification is a requirement. Which QoS solution meets this requirement?

A. marking traffic at the access layer with DSCP to support the traffic flows
B. IntServ model with RSVP to support the traffic flows
C. DiffServ model with PHB to support the traffic flows
D. marking traffic at the access layer with CoS to support the traffic flows

Antwort: B
