NEW QUESTION 34 
R1 is configured with the default configuration of OSPF.
From the following list of IP addresses configured on R1, which address will the OSPF process select as the router ID?
- A. 192.168.0.1
- B. 172.16.2.225
- C. 172.16.2.1
- D. 172.16.1.1
Answer: A
Explanation:
The Router ID (RID) is an IP address used to identify the router and is chosen using the following sequence:
+
The highest IP address assigned to a loopback (logical) interface.
+
If a loopback interface is not defined, the highest IP address of all active router's physical interfaces will be chosen.
+
The router ID can be manually assigned
In this case, because a loopback interface is not configured so the highest active IP address
192.168.0.1 is chosen as the router ID.
NEW QUESTION 35
Which two of these statements regarding RSTP are correct? (Choose two.)
- A. RSTP is a proprietary implementation of IEEE 802.1D STP.
- B. RSTP cannot operate with PVST+.
- C. RSTP defines no new port states.
- D. RSTP defines new port roles.
- E. RSTP is compatible with the original IEEE 802.1D STP.
Answer: D,E
Explanation:
http://www.cisco.com/en/US/tech/tk389/tk621/technologies_white_paper09186a0080094cfa.shtml
Port Roles The role is now a variable assigned to a given port. The root port and designated port roles remain, while the blocking port role is split into the backup and alternate port roles. The Spanning Tree Algorithm (STA) determines the role of a port based on Bridge Protocol Data Units (BPDUs). In order to simplify matters, the thing to remember about a BPDU is there is always a method to compare any two of them and decide whether one is more useful than the other. This is based on the value stored in the BPDU and occasionally on the port on which they are received. This considered, the information in this section explains practical approaches to port roles.
Compatibility with 802.1D RSTP is able to interoperate with legacy STP protocols. However, it is important to note that the inherent fast convergence benefits of 802.1w are lost when it interacts with legacy bridges.
NEW QUESTION 36
What occurs on a Frame Relay network when the CIR is exceeded?
- A. All UDP traffic is marked discard eligible and a BECN is sent.
- B. All traffic exceeding the CIR is marked discard eligible.
- C. All TCP traffic is marked discard eligible and a BECN is sent.
- D. All TCP traffic is marked discard eligible.
Answer: B
Explanation:
Committed information rate (CIR): The minimum guaranteed data transfer rate agreed to by the Frame Relay switch. Frames that are sent in excess of the CIR are marked as discard eligible (DE) which means they can be dropped if the congestion occurs within the Frame Relay network. Note: In the Frame Relay frame format, there is a bit called Discard eligible (DE) bit that is used to identify frames that are first to be dropped when the CIR is exceeded.
NEW QUESTION 37

- E. The PVC is not configured on the local switch.
Answer: D
NEW QUESTION 39
Users have been complaining that their Frame Relay connection to the corporate site is very slow. The network administrator suspects that the link is overloaded. Based on the partial output of the Router # show frame relay pvc command shown in the graphic, which output value indicates to the local router that traffic sent to the corporate site is experiencing congestion?
- A. in FECN packets 147
- B. DLCI=100
- C. last time PVC status changed 00:25:40
- D. in DF packets 0
- E. in BECN packets 192
Answer: E
Explanation:
First we should grasp the concept of BECN & FECN through an example:
Suppose Router A wants to send data to Router B through a Frame Relay network. If the network is congested, Switch 1 (a DCE device) will set the FECN bit value of that frame to 1, indicating that frame experienced congestion in the path from source to destination. This frame is forwarded to Switch 2 and to Router B (with the FECN bit = 1). Switch 1 knows that the network is congesting so it also sends frames back to Router A with BECN bit set to 1 to inform that path through the network is congested.
In general, BECN is used on frames traveling away from the congested area to warn source devices that congestion has occurred on that path while FECN is used to alert receiving devices if the frame experiences congestion.
BECN also informs the transmitting devices to slow down the traffic a bit until the network returns to normal state. The question asks "which output value indicates to the local router that traffic sent to the corporate site is experiencing congestion" which means it asks about the returned parameter which indicates congestion ->BECN.
NEW QUESTION 40
A food delivery company launches a campaign to attract new subscribers. An advertiser creates two types of video ads: educational and promotional.
The educational video ads focus on increasing people's awareness of the brand. The video ads reach an audience of people, ages 18-50. Previous purchasers and active subscribers are excluded. The ads are also delivered to a Lookalike Audience based on current customers.
The promotional video ads include promotional codes that encourage new subscriptions and are delivered to people who engaged with the earlier ads. The advertiser launches the ads a few weeks before operating in new markets so the company can develop a pool of customers who are ready to receive the product when operations start.
Which metric should be the primary KPI to determine the causal effectiveness of the Facebook ad campaign?
- A. Number of total subscriptions
- B. Number of incremental subscriptions
- C. Brand favorability lift
- D. Brand awareness lift
Answer: A
NEW QUESTION 41
Which type of EIGRP route entry describes a feasible successor?
- A. a primary route, stored in the topology table
- B. a backup route, stored in the topology table
- C. a backup route, stored in the routing table
- D. a primary route, stored in the routing table
Answer: B
Explanation:
http://www.cisco.com/en/US/tech/tk365/technologies_tech_note09186a0080093f07.shtml
Feasible Successors A destination entry is moved from the topology table to the routing table when there is a feasible successor. All minimum cost paths to the destination form a set. From this set, the neighbors that have an advertised metric less than the current routing table metric are considered feasible successors. Feasible successors are viewed by a router as neighbors that are downstream with respect to the destination. These neighbors and the associated metrics are placed in the forwarding table. When a neighbor changes the metric it has been advertising or a topology change occurs in the network, the set of feasible successors may have to be re-evaluated. However, this is not categorized as a route recomputation. Feasible successor is a route whose Advertised Distance (AD) is less than the Feasible Distance (FD) of the current best path. A feasible successor is a backup route, which is not stored in the routing table but, stored in the topology table.
NEW QUESTION 42
Refer to the exhibit.
Each of these four switches has been configured with a hostname, as well as being configured to run RSTP. No other configuration changes have been made. Which three of these show the correct RSTP port roles for the indicated switches and interfaces? (Choose three.)
- A. SwitchC, Fa0/2, root
- B. SwitchA, Fa0/1, root
- C. SwitchA, Fa0/2, designated
- D. SwitchB, Gi0/2, root
- E. SwitchB, Gi0/1, designated
- F. SwitchD, Gi0/2, root
Answer: B,C,F
Explanation:
The question says "no other configuration changes have been made" so we can understand these
switches have the same bridge priority. SwitchC has lowest MAC address so, it will become root
bridge and 2 of its ports (Fa0/1 & Fa0/2) will be designated ports (DP). Because SwitchC is the
root bridge the 2 ports nearest SwitchC on SwitchA (Fa0/1) and SwitchD (Gi0/2) will be root ports
(RP) -> B and F are correct.
SwitchB must have a root port so which port will it choose? To answer this question we need to
know about STP cost and port cost.
In general, "cost" is calculated based on bandwidth of the link. The higher the bandwidth on a link,
the lower the value of its cost. Below are the cost values you should memorize:
Link speed Cost SwitchB will choose the interface with lower cost to the root bridge as the root
port so we must calculate the cost on interface Gi0/1 & Gi0/2 of SwitchB to the root bridge. This
can be calculated from the "cost to the root bridge" of each switch because a switch always advertises its cost to the root bridge in its BPDU. The receiving switch will add its local port cost value to the cost in the BPDU. SwitchC advertises its cost to the root bridge with a value of 0. Switch D adds 4 (the cost value of 1Gbps link) and advertises this value (4) to SwitchB. SwitchB adds another 4 and learns that it can reach SwitchC via Gi0/1 port with a total cost of 8. The same process happens for SwitchA and SwitchB learns that it can reach SwitchC via Gi0/2 with a total cost of 23 -> Switch B chooses Gi0/1 as its root port. Now our last task is to identify the port roles of the ports between SwitchA & SwitchB. It is rather easy as the MAC address of SwitchA is lower than that of SwitchB so Fa0/2 of SwitchA will be designated port while Gi0/2 of SwitchB will be alternative port.
NEW QUESTION 43
Which parameter or parameters are used to calculate OSPF cost in Cisco routers?
- A. Bandwidth, MTU, Reliability, Delay, and Load
- B. Bandwidth
- C. Bandwidth, Delay, and MTU
- D. Bandwidth and Delay
Answer: B
Explanation:
http://www.cisco.com/en/US/tech/tk365/technologies_white_paper09186a0080094e9e.shtml#t6
OSPF Cost
The cost (also called metric) of an interface in OSPF is an indication of the overhead required to send packets across a certain interface. The cost of an interface is inversely proportional to the bandwidth of that interface. A higher bandwidth indicates a lower cost. There is more overhead (higher cost) and time delays involved in crossing a 56k serial line than crossing a 10M Ethernet line. The formula used to calculate the cost is: Cost= 10000 0000/bandwidth in bps
For example, it will cost 10 EXP8/10 EXP7 = 10 to cross a 10M Ethernet line and will cost 10 EXP8/1544000 =64 to cross a T1 line. By default, the cost of an interface is calculated based on the bandwidth; you can force the cost of an interface with the ip ospf cost <value> interface sub configuration mode command.

NEW QUESTION 45
What are three characteristics of the OSPF routing protocol? (Choose three.)
- A. OSPF routers send the complete routing table to all directly attached routers.
- B. It uses cost to determine the best route.
- C. It uses the DUAL algorithm to determine the best route.
- D. It converges quickly.
- E. OSPF is a classful routing protocol.
- F. OSPF routers discover neighbors before exchanging routing information.
Answer: B,D,F
Explanation:
Open Shortest Path First Reference:
http://docwiki.cisco.com/wiki/Open_Shortest_Path_First
Explanation:
Additional OSPF features include equal-cost, multipath routing, and routing based on upper-layer type-ofservice
(TOS) requests. TOS-based routing supports those upper-layer protocols that can specify particular
types of service. An application, for example, might specify that certain data is urgent. If OSPF has high-priority
links at its disposal, these can be used to transport the urgent datagram.
OSPF supports one or more metrics. If only one metric is used, it is considered to be arbitrary, and TOS is not supported. If more than one metric is used, TOS is optionally supported through the use of a separate metric (and, therefore, a separate routing table) for each of the eight combinations created by the three IP TOS bits (the delay, throughput, and reliability bits). For example, if the IP TOS bits specify low delay, low throughput, and high reliability, OSPF calculates routes to all destinations based on this TOS designation. IP subnet masks are included with each advertised destination, enabling variable-length subnet masks. With variable-length subnet masks, an IP network can be broken into many subnets of various sizes. This provides network administrators with extra network-configuration flexibility.
