Section1 – Implement an EIGRP based solution, given a network design and a set of requirements
QUESTION NO: 26
Refer to the exhibit. EIGRP has been configured on all routers in the network. The command metric weights 0 0 1 0 0 has been added to the EIGRP process so that only the delay metric is used in the path calculations. Which router will R1 select as the successor and feasible successor for Network A?
A. R4 becomes the successor for Network A and will be placed in the routing table. R2 becomes the feasible successor for Network A.
B. R4 becomes the successor for Network A and will be included in the routing table. No feasible successor will be selected as the advertised distance from R2 is higher than the feasible distance.
C. R2 becomes the successor and will be placed in the routing table. R4 becomes the feasible successor for Network A.
D. R2 becomes the successor and will be placed in the routing table. No feasible successor will be selected as the reported distance from R4 is lower than the feasible distance.
QUESTION NO: 27
Which three statements are true about EIGRP route summarization? (Choose three.)
A. When manual summarization is configured, the router immediately creates a route that points to null0 interface.
B. Manual route summarization is configured in router configuration mode when the router is configured for EIGRP routing.
C. Manual route summarization is configured on the interface.
D. The ip summary-address eigrp command generates a default route with an administrative distance of 5.
E. When manual summarization is configured, the summary route will use the metric of the largest
specific metric of the summary routes.
F. The ip summary-address eigrp command generates a default route with an administrative
distance of 90.
The purpose of route summarization is small routing tables, smaller updates. On major network boundaries, subnetworks are summarized to a single classful network and automatic route summarization is enabled by default. Manual route summarization can be configured on per interface basis. When summarization is configured on an interface, the router immediately creates a route pointing to null0.
Route summarization works in conjunction with the ip summary-address eigrp interface configuration command, in which additional summarization can be performed. If automatic summarization is in effect, there usually is no need to configure network level summaries using the ip summary-address eigrp command. You can configure a summary aggregate address for a specified interface. If there are any more specific routes in the routing table, EIGRP will advertise the summary address out the interface with a metric equal to the minimum of all more specific routes.
QUESTION NO: 28
Refer to the exhibit. The network administrator is trying to configure mutual redistribution between EIGRP and OSPF. Autosummarization in EIGRP 100 AS is disabled. After adding OSPF configuration to router B1, the network administrator checked the routing table of router B2, but none of the EIGRP routes appeared there.
To redistribute the EIGRP AS 100 routes into OSPF, which command should be added, or edited, on router B1 under router ospf 10?
A. redistribute eigrp 100 metric-type 1
B. redistribute eigrp 100 subnets
C. no auto-summary 10.0.0.0 255.0.0.0
D. area 0 range 10.10.0.0 255.255.0.0
QUESTION NO: 29
Refer to the exhibit. Looking at the topology diagram and the partial router configurations shown, which statement is true?
A. A routing loop will occur due to mutual route redistribution occurring on R1 and R2.
B. Suboptimal routing will occur due to mutual route redistribution occurring on R1 and R2.
C. Additional route filtering configurations using route maps and ACLs are required on the R1 and R2 routers to prevent routing loops.
D. R2 will not be able to redistribute the EIGRP subnets into OSPF, because R2 is missing the default seed metric for OSPF.
E. The 10.1.1.0/24 subnet will appear as 10.0.0.0/8 in the R5 routing table.
QUESTION NO: 30
Based on the exhibited output, which three statements are true? (Choose three.)
A. R1 is in AS 200.
B. R1 will load balance between three paths to reach the 192.168.1.48/28 prefix because all three paths have the same advertised distance (AD) of 40512000.
C. The best path for R1 to reach the 192.168.1.48/28 prefix is via 192.168.1.66.
D. 40512000 is the advertised distance (AD) via 192.168.1.66 to reach the 192.168.1.48/28 prefix.
E. All the routes are in the passive mode because these routes are in the hold-down state.
F. All the routes are in the passive mode because R1 is in the query process for those routes.
It can be determined that AS 200 is used, from the fact that the IS-IS process ID is labeled as 200.
The best path to reach the network 192.168.1.48/28 is the first one displayed in the routing table.
This can be further demonstrated by the fact that the metric is less than the alternative route, via serial 0. Finally, the AD can be found by viewing the second number within the parentheses, which in this case is 40512000.
