NEW QUESTION # 62
Exhibit
Referring to the exhibit, which three statements are correct about route 10 0 0.0/16 when using the default BGP advertisement rules'? (Choose three.)
Answer: A,D,E
NEW QUESTION # 63 
Click the Exhibit button.
You are troubleshooting an issue for a customer site that uses 10.10.0.0/24 in AS 65224, but you see another AS in the AS path.
Referring to the exhibit, what is the cause of the problem?
Answer: C
Explanation:
In the given exhibit, you are observing the BGP routing information for the prefix 10.10.0.0/24. The AS path for this prefix shows `65000 {65137 65224}`. To understand the issue, let's analyze each aspect of the information provided and the options given:
1. **AS Path Analysis**:
- The AS path attribute in BGP is a list of AS numbers that a route advertisement has traversed.
- In this case, the AS path `65000 {65137 65224}` indicates that the route to 10.10.0.0/24 has been advertised through AS 65000, which includes AS 65137 and AS 65224.
2. **Understanding AS Path Prepending**:
- AS path prepending is a technique used by AS administrators to artificially lengthen the AS path.
- By adding their own AS number multiple times into the AS path, they make a route less attractive to others.
- Here, AS 65000 is showing `65137` as part of its AS path, suggesting it might be prepending to manipulate routing decisions.
3. **Options Analysis**:
- **Option A**: "AS 65000 is pre-pending AS 65137 to route advertisements."
- This option suggests that AS 65000 is deliberately adding AS 65137 to the AS path. This matches the observed AS path, where AS 65000 has prepended `65137`.
- Therefore, this is the correct explanation.
- **Option B**: "The local AS is receiving two equal cost routes to 10.10.0.0/24."
- There is no evidence in the exhibit to support the presence of two equal-cost routes.
- **Option C**: "The local AS is in the process of withdrawing the route from AS 65137."
- Route withdrawal would not cause the AS path to include `65000 {65137 65224}`.
- **Option D**: "AS 65137 is advertising the 10.10.0.0/24 prefix."
- While AS 65137 is part of the path, it does not explain the presence of AS 65000 in the path, making this option incorrect.
**Conclusion**:
The AS path `65000 {65137 65224}` is indicative of AS 65000 prepending AS 65137. Therefore, the correct answer is:
**A. AS 65000 is pre-pending AS 65137 to route advertisements.**

NEW QUESTION # 64
Exhibit
user@Rl show configuration interpolated-profile { interpolate {
fill-level [ 50 75 drop-probability [ > }
class-of-service drop-profiles
];
20 60 ];
Which two statements are correct about the class-of-service configuration shown in the exhibit? (Choose two.)
Answer: A,B
Explanation:
class-of-service (CoS) is a feature that allows you to prioritize and manage network traffic based on various criteria, such as application type, user group, or packet loss priority. CoS uses different components to classify, mark, queue, schedule, shape, and drop traffic according to the configured policies.
One of the components of CoS is drop profiles, which define how packets are dropped when a queue is congested. Drop profiles use random early detection (RED) algorithm to drop packets randomly before the queue is full, which helps to avoid global synchronization and improve network performance. Drop profiles can be discrete or interpolated. A discrete drop profile maps a specific fill level of a queue to a specific drop probability. An interpolated drop profile maps a range of fill levels of a queue to a range of drop probabilities and interpolates the values in between.
In the exhibit, we can see that the class-of-service configuration shows an interpolated drop profile with two fill levels (50 and 75) and two drop probabilities (20 and 60). Based on this configuration, we can infer the following statements:
The drop probability jumps immediately from 20% to 60% when the queue level reaches 75% full. This is not correct because the drop profile is interpolated, not discrete. This means that the drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to 75% full. The drop probability for any fill level between 50% and 75% can be calculated by using linear interpolation formula.
The drop probability gradually increases from 20% to 60% as the queue level increases from 50% full to
75% full. This is correct because the drop profile is interpolated and uses linear interpolation formula to calculate the drop probability for any fill level between 50% and 75%. For example, if the fill level is
60%, the drop probability is 28%, which is calculated by using the formula: (60 - 50) / (75 - 50) * (60 -
20) + 20 = 28.
To use this drop profile, you reference it in a scheduler. This is correct because a scheduler is a component of CoS that determines how packets are dequeued from different queues and transmitted on an interface. A scheduler can reference a drop profile by using the random-detect statement under the
[edit class-of-service schedulers] hierarchy level. For example: scheduler test { transmit-rate percent 10; buffer-size percent 10; random-detect test-profile; } To use this drop profile, you apply it directly to an interface. This is not correct because a drop profile cannot be applied directly to an interface. A drop profile can only be referenced by a scheduler, which can be applied to an interface by using the scheduler-map statement under the [edit class-of-service interfaces] hierarchy level. For example: interfaces ge-0/0/0 { unit 0 { scheduler-map test-map; } }
NEW QUESTION # 65
Exhibit
Referring to the exhibit, you are receiving the 192.168 0 0/16 route on both R3 and R4 from your EBGP neighbor You must ensure that R1 and R2 receive both BGP routes from the route reflector In this scenario, which BGP feature should you configure to accomplish this behavior?
Answer: D
Explanation:
BGP add-path is a feature that allows the advertisement of multiple paths through the same peering session for the same prefix without the new paths implicitly replacing any previous paths. This behavior promotes path diversity and reduces multi-exit discriminator (MED) oscillations. BGP add-path is implemented by adding a path identifier to each path in the NLRI. The path identifier can be considered as something similar to a route distinguisher in VPNs, except that a path ID can apply to any address family. Path IDs are unique to a peering session and are generated for each network3. In this question, we have a route reflector (RR) that receives two routes for the same prefix (192.168.0.0/16) from an EBGP neighbor. By default, the RR will only advertise its best path to its clients (R1 and R2). However, we want R1 and R2 to receive both routes from the RR. To achieve this, we need to configure BGP add-path on the RR and enable it to send multiple paths for the same prefix to its clients.
NEW QUESTION # 66 
Click the Exhibit button.
Referring to the exhibit, which two statements are true? (Choose two.)
Answer: A,D
Explanation:
In the exhibit, the output of the `show route protocol bgp` command is shown for the prefix `172.16.20.4/30`.
Let's analyze the provided BGP routing table to determine which statements are correct.
1. **AS Path Analysis**:
- The AS path for the route `172.16.20.4/30` is shown as `2 I`.
- This indicates that the route was learned from AS 2 and it is an internal (iBGP) route within the same AS.
2. **Multiple Paths**:
- The route has two next-hop IP addresses: `10.0.18.2` via interface `ge-1/0/4.0` and `10.0.19.2` via interface
`ge-1/0/5.0`.
- This indicates that BGP multipath is configured, which allows multiple equal-cost paths to be used for load balancing.
- BGP multipath must be explicitly configured to use multiple paths for the same prefix.
3. **Multihop vs. Multipath**:
- **Multihop Configuration**: This is typically used for establishing BGP sessions with peers that are not directly connected. It is not related to load balancing.
- **Multipath Configuration**: This is used to enable load balancing across multiple paths for the same prefix, which is the case here.
**Conclusion**:
Given the above analysis:
- **C. This route is learned from the same AS number**: Correct. The AS path `2 I` indicates the route was learned from the same AS number (AS 2).
- **D. The multipath configuration is used for load balancing**: Correct. The presence of multiple next-hops indicates that BGP multipath is configured for load balancing.
Thus, the correct answers are:
**C. This route is learned from the same AS number.**
**D. The multipath configuration is used for load balancing.**
