A BGP device receives a route carrying an unknown attribute from a peer but does not know whether other devices need the attribute. In this case, the BGP device retains this attribute when advertising the route to other peers. Which of the following attributes is of this type?
Answer(s): A
Transitive vs. Non-Transitive AttributesThe Community attribute is a transitive optional attribute, meaning that if a router receives a route with this attribute and does not understand its purpose, the router retains and propagates it to other peers.Other options, such as AS_Path and MED, are well-defined mandatory or optional attributes with specific purposes.HCIP-Datacom-Core ReferenceThe behavior of optional transitive attributes is detailed in the BGP protocol and attribute chapters.
When configuring an ACL on a router, you can specify a unique number or name to identify the ACL. Once a named ACL is created, it cannot be modified. You can only delete the named ACL and reconfigure it.
Answer(s): B
ACL ModificationNamed ACLs can be modified after their creation. Unlike numbered ACLs, named ACLs provide greater flexibility for editing individual rules without deleting the entire ACL.Therefore, the statement is incorrect.HCIP-Datacom-Core ReferenceThe flexibility and editability of named ACLs are discussed in the ACL configuration sections.
ACLs are a common tool for matching routes. ACLs are classified into multiple types based on ACLrule functions. An ACL can be identified by a number, and the number range for each type of ACLs is different. Which of the following type of ACLs are numbered from 4000 to 4999?
ACL Number RangesBasic ACLs: Numbered from 2000 to 2999.Advanced ACLs: Numbered from 3000 to 3999.Layer 2 ACLs: Numbered from 5000 to 5999.User-defined ACLs: Numbered from 4000 to 4999.HCIP-Datacom-Core ReferenceACL classifications and their number ranges are covered in the ACL principles and configuration chapters.
ACLs are a common matching tool in routing policies. An ACL can be configured on a router to match routes.
ACL in Routing PoliciesACLs are frequently used in routing policies to match specific routes based on criteria such as sourceIP, destination IP, and more. This allows ACLs to influence route redistribution, filtering, and forwarding decisions.HCIP-Datacom-Core ReferenceACL applications in routing policies are discussed in the routing policy chapters.
Both MQC and PBR can be applied on device interfaces to filter received and sent packets or control packet forwarding paths.
MQC and PBRMQC (Modular QoS Command-Line Interface): Applied to interfaces for classifying and controlling traffic.PBR (Policy-Based Routing): Used to influence packet forwarding based on policies rather than traditional routing tables.Both MQC and PBR can be configured on device interfaces to filter incoming/outgoing packets or control their forwarding paths.HCIP-Datacom-Core ReferenceThe use of MQC and PBR on device interfaces is elaborated in the QoS and routing control chapters.

question 8 - can cloudtrail be used for storing jobs? based on aws - aws cloudtrail is used for governance, compliance and investigating api usage across all of our aws accounts. every action that is taken by a user or script is an api call so this is logged to [aws] cloudtrail. something seems incorrect here.
question 13 tda - c01 answer : quick table calculation -> percentage of total , compute using table down
pls share teh dump
question 44 answer is user risk
please post the questions for preparation
thanks for the questions
please reopen it now ..its really urgent
these practice exam questions were exactly what i needed. the variety of questions and the realistic exam-like environment they created helped me assess my strengths and weaknesses. i felt more confident and well-prepared on exam day, and i owe it to this exam dumps!
