NEW QUESTION 30
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 DF packets 0
- B. DLCI=100
- C. in FECN packets 147
- D. in BECN packets 192
- E. last time PVC status changed 00:25:40
Answer: D
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 32
Refer to the exhibit.
At the end of an RSTP election process, which access layer switch port will assume the discarding role?
- A. Switch3, port fa0/1
- B. Switch3, port Gi0/1
- C. Switch4, port fa0/2
- D. Switch4, port fa0/11
- E. Switch3, port fa0/12
- F. Switch3, port Gi0/2
Answer: D
Explanation:
In this question, we only care about the Access Layer switches (Switch3 & 4). Switch 3 has a lower bridge ID than Switch 4 (because the MAC of Switch3 is smaller than thatof Switch4) so both ports of Switch3 will be in forwarding state. The alternative port will surely belong to Switch4. Switch4 will need to block one of its ports to avoid a bridging loop between the two switches. But how does Switch4 select its blocked port? Well, the answer is based on the BPDUs it receives from Switch3. A BPDU is superior than another if it has:
1. A lower Root Bridge ID2. A lower path cost to the Root3. A lower Sending Bridge ID4. A lower Sending Port ID
These four parameters are examined in order. In this specific case, all the BPDUs sent by Switch3 have the same Root Bridge ID, the same path cost to the Root and the same Sending Bridge ID. The only parameter left to select the best one is the Sending Port ID (Port ID = port priority + port index). In this case the port priorities are equal because they use the default value, so Switch4 will compare port index values, which are unique to each port on the switch, and because Fa0/12 is inferior to Fa0/1, Switch4 will select the port connected with Fa0/1 (of Switch3) as its root port and block the other port -> Port fa0/11 of Switch4 will be blocked (discarding role)

NEW QUESTION 35
Which three statements about RSTP are true? (Choose three.)
- A. RSTP port states are blocking, discarding, learning, or forwarding.
- B. RSTP significantly reduces topology reconverging time after a link failure.
- C. RSTP uses the same timer-based process as STP on point-to-point links.
- D. RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.
- E. RSTP also uses the STP proposal-agreement sequence.
- F. RSTP expands the STP port roles by adding the alternate and backup roles.
Answer: B,D,F
Explanation:
http://www.cisco.com/en/US/tech/tk389/tk621/technologies_white_paper09186a0080094cfa.shtml
Convergence Cisco enhanced the original 802.1D specification with features such as Uplink Fast, Backbone Fast, and Port Fast to speed up the convergence time of a bridged network. The drawback is that these mechanisms are proprietary and need additional configuration.
Alternate and Backup Port Roles These two port roles correspond to the blocking state of 802.1D. A blocked port is defined as not being the designated or root port. A blocked port receives a more useful BPDU than the one it sends out on its segment.
Remember that a port absolutely needs to receive BPDUs in order to stay blocked. RSTP introduces these two roles for this purpose. Rapid Transition to Forwarding State Rapid transition is the most important feature introduced by 802.1w. The legacy STA passively waited for the network to converge before it turned a port into the forwarding state. The achievement of faster convergence was a matter of tuning the conservative default parameters (forward delay and max_age timers) and often put the stability of the network at stake. The new rapid STP is able to actively confirm that a port can safely transition to the forwarding state without having to rely on any timer configuration. There is now a real feedback mechanism that takes place between RSTP-compliant bridges. In order to achieve fast convergence on a port, the protocol relies upon two new variables: edge ports and link type.
NEW QUESTION 36
What information does a router running a link-state protocol use to build and maintain its topological database? (Choose two.)
- A. hello packets
- B. TTL packets from designated routers
- C. SAP messages sent by other routers
- D. routing tables received from other link-state routers
- E. beacons received on point-to-point links
- F. LSAs from other routers
Answer: A,F
NEW QUESTION 37
Refer to the exhibit.
Which statement describes DLCI 17?
- A. DLCI 17 describes a PVC on R2. It cannot be used on R3 or R1.
- B. DLCI 17 describes the ISDN circuit between R2 and R3.
- C. DLCI 17 describes the dial-up circuit from R2 and R3 to the service provider.
- D. DLCI 17 is the Layer 2 address used by R2 to describe a PVC to R3.
Answer: D
Explanation:
DLCI stands for Data Link Connection Identifier. DLCI values are used on Frame Relay interfaces to distinguish between different virtual circuits. DLCIs have local significance because, the identifier references the point between the local router and the local Frame Relay switch to which the DLCI is connected.

NEW QUESTION 39
A spa wants to increase awareness of its package holiday deals internationally. It has been investing heavily in influencer marketing and social media campaigns. Its most popular influencer recently posted a video about the retreat that received 500,000 likes in the first day. The spa gained more than 3,000 new followers on its Instagram account.
Given the outcome of this organic post, the spa decides to pull their paid social media campaigns because this spend generates only a quarter of the engagement compared to influencer posts.
What advice should the analyst share about measuring success in this way?
- A. The spa should review the number of new followers at least one month later before pulling spend from paid campaigns.
- B. It is always better to diversify spend equally across multiple marketing strategies.
- C. Engagement metrics such as likes, comments and followers may not translate into incremental business value such as brand equity or sales.
- D. The spa should review the number of shares that the original post achieved before pulling spend from paid campaigns.

NEW QUESTION 41
An advertiser is running a campaign on a new advertising platform where they will spend $100,000 over the course of four weeks with the goal of driving incremental purchases. The campaign targets men, ages 18-34 and does not hold out any users from seeing the advertiser's ads. Typically, the advertising platform sees that campaigns at this spend level reach about 75% of the target audience. The analytics team at the advertising platform recommends measuring the effect of the campaign by measuring the conversions driven by all users who saw an ad versus all users who did not see an ad.
What is the primary limitation of this approach?
- A. It is not possible to calculate the statistical significance of this test
- B. It can end up with different sample sizes, making the test and control group uncomparable
- C. It can introduce a degree of imbalance across the test and control groups
- D. It does not control for unobservable effects impacting the test group

NEW QUESTION 44
Which type of EIGRP route entry describes a feasible successor?
- A. a primary route, stored in the routing table
- B. a backup route, stored in the routing table
- C. a primary route, stored in the topology table
- D. a backup route, stored in the topology table
Answer: D
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.

Refer to the exhibit.
The network associate is configuring OSPF on the Core router. All the connections to the branches should be participating in OSPF. The link to the ISP should NOT participate in OSPF and should only be advertised as the default route. What set of commands will properly configure the Core router?
- A. Core(config-router)# default-information originate Core(config-router)# network 10.10.2.32 0.0.0.31 area 0 Core(config-router)# exit Core(config)# ip route 0.0.0.0 0.0.0.0 10.10.2.14

Answer: C
Explanation:
There are two ways to inject a default route into a normal area.1. If the ASBR already has the default route in its routing table, you can advertise theexisting 0.0.0.0/0 into the OSPF domain with the default-information originate router configuration command.2. If the ASBR doesn't have a default route, you can add the keyword always to the default-information originate command (default-information originate always).This command will advertise a default route into the OSPF domain, regardless of whether it has a route to 0.0.0.0. Another benefit of adding always keyword is that it can add stability to the internetwork. For example, if the ASBR is learning a default route from another routing domain such as RIP and this route is flapping, then without the always keyword, each time the route flaps, the ASBR will send a new Type 5 LSA into the OSPF domain causing some instability inside the OSPF domain. With the always keyword, the ASBR will advertise the default inside the OSPF domain always,In the example shown here, only choice C is correct as the wildcard mask correctly specifies the 10.10.2.16 0.0.0.15 networks, which include all IP addresses in the 10.10.2.16-10.10.2.31 range. In this question we were told that the ISP link should NOT be configured for OSPF, making choice A incorrect. http://www.cisco.com/en/US/tech/tk365/technologies_configuration_example09186a00801ec9f0.s html
