You are a network technician, study the exhibit carefully.

What must be done on router A in order to make EIGRP work effectively in a Frame Relay multipoint environment?
A. Issue the command bandwidth 56 on the physical interface.
B. Issue the command bandwidth 56 on each subinterface.
C. Issue the command bandwidth 224 on each subinterface.
D. Issue the command bandwidth 224 on the physical interface.
Answer: D
Explanation/Reference:
Explanation
In Frame Relay, all neighbors share the same bandwidth, regardless of the actual CIR of each individual PVC. In this case the CIR of each PVC is the same so we can find the bandwidth of the main interface (multipoint connection interface) by 56 x 4 = 224.
Notice that if the bandwidth on each PVC is not equal then we get the lowest bandwidth to multiply.

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.
Answer: E
Explanation/Reference:
Explanation
RIPv1 is a classful routing protocol so the subnet 10.1.1.0/24 will be summarized to 10.0.0.0/8 in the R5 routing table. If we use RIPv2 on R1, R5 and use the no auto-summary command on R1 then the 10.1.1.0 subnet will appear in the routing table of R5. Notice that even if the auto-summary command is configured under router eigrp 1 of R1 but when redistributing into another routing protocol EIGRP still advertises the detailed network.

Which two functions are completely independent when implementing NAT64 over NAT-PT? (Choose two.)
A. DNS
B. NAT
C. port redirection
D. stateless translation
E. session handling
Answer: A,B
Explanation/Reference:
Explanation:
Network Address Translation IPv6 to IPv4, or NAT64, technology facilitates communication between IPv6- only and IPv4-only hosts and networks (whether in a transit, an access, or an edge network). This solution allows both enterprises and ISPs to accelerate IPv6 adoption while simultaneously handling IPv4 address depletion. The DNS64 and NAT64 functions are completely separated, which is essential to the superiority of NAT64 over NAT-PT.

Refer to the exhibit.

A company would prefer all Internet-bound OSPF routed traffic to use ISP ABC with ISP DEF as a backup.
As the network consultant, what three configuration changes should you make? (Choose three.)
A. The default-information originate command should be configured on router B1 and B4.
B. The default-information originate command should be configured on router B2 and B3.
C. If the metric value for ISP ABC is set at the default, the ISP DEF metric value should be set to 1.
D. If the metric value for ISP ABC is set at the default, the ISP DEF metric value should be set to 25.
E. The metric type value should be set to type 1.
F. The metric type value should be set to type 2.
Answer: B,D,F
Explanation/Reference:
Explanation
Routers B2 & B3 need to advertise a default route to the Internet for inside OSPF routers so we should use the default-information originate command with a default route (something like ip route 0.0.0.0 0.0.0.0 ) pointing to the ISP router.
If no metric is specified, OSPF puts a default value of 20 when redistributing routes from all protocols except BGP routes (BGP routes get a metric of 1). We use ISP DEF as a backup so its metric value should be set to a higher value than 20.
There are two types of external routes: external type 1 and external type 2. The difference between the two is in the way the cost (metric) of the route is being calculated:
+ The cost of a type 2 route is always the external cost, irrespective of the interior cost to reach that route.
+ Type 1 cost is the addition of the external cost and the internal cost used to reach that route.
-> We should configure the type 2 external route to make sure the ISP ABC is always referred over ISP DEF because internal routing does not determine the path. Note: E2 is the default external metric, but E1 is preferred over E2 if two equal-cost paths exist.

NEW QUESTION NO: 7
In which state do DR and BDR establish adjacency with each OSPF router in the network?
A. Init State
B. Exstart State
C. Exchange State
D. Loading State
Answer: A
Explanation/Reference:
Explanation: DR and BDR will only establish adjacency with each OSPF router on broadcast multiacacess networks. So Init state is the correct answer.

What is the purpose of configuring the router as a PPPoE client?
A. to provide VPN access over L2TP
B. to enable PPP session from the router to the termination device at the headend for metro Ethernet connectivity
C. for DSL connectivity and removing the need for the end-user PC to run the PPPoE client software
D. for connecting the router to a cable modem, which bridges the Ethernet frames from the router to the cable modem termination system
Answer: C
Explanation/Reference:
DSL Technology used PPPoE protocol (service provide end) and user end required to be used same Protcol running as client to communicate with it
