NEW QUESTION # 114
What is a key consideration when configuring network tests using Thousand Eyes and Meraki Insights?
Answer: B
Explanation:
A key consideration when configuring network tests is minimizing latency to ensure accurate performance measurement and analysis in network assurance.
NEW QUESTION # 115
Considering the observed network behavior and the information in the exhibits, which action would be the most appropriate next step for the network administrator to take?
Answer: A
Explanation:
TheDesigning and Implementing Enterprise Network Assurance (300-445 ENNA)framework emphasizes that the goal of internet intelligence is to enable rapid and accurate escalation to the party responsible for a service degradation. Based on the evidence of a BGP Hijack identified in the previous question, the issue is occurring entirely within the public internet ecosystem.
The most appropriate next step is toreach out to the Internet Service Provider (ISP) to report the suspected BGP hijacking incident(Option B). Since the traffic is being misdirected by an external Autonomous System (AS 10297) before it reaches the intended destination (AS 16509), the fix must occur at the routing policy level of the major transit providers. The network administrator should provide the ISP with the ThousandEyes "Share Link" or screenshots showing the path change and the unauthorized AS announcement, as this data serves as proof to accelerate the ISP's mitigation efforts, such as implementing prefix filters or contacting the offending network.
Other options are ineffective for this specific scenario:
* Option A:The path visualization shows that traffic is successfully leaving the local network and reaching the public internet; the problem is many hops away from the internal routers.
* Option C:Blocking trafficfromAS 10297 does not solve the problem of your traffic beingattractedto it.
The hijack affects how the rest of the world (including your ISP) sees the route to your destination.
* Option D:DNS is not the issue; the agent successfully resolved the hostname to the correct IP, but the BGP layer misdirected the packets at the routing level.
By identifying the issue as an external routing event, the administrator avoids wasting internal resources and directly triggers the necessary external remediation.
NEW QUESTION # 116
The alert shown in the exhibit is designed to detect which of the following network security issues?
Answer: A
Explanation:
As shown in Exhibit 4.1-1 (image_6e19fb.png), the alert rule is configured for the BGP layer with the name " AS origin AS 1234 " . The critical logic is defined in the Alert Conditions section, which specifies: BGP Origin meets all of: ASN not in 1234.
This specific configuration is the standard method used in ThousandEyes to detect BGP hijacking (Option C). BGP hijacking occurs when an unauthorized Autonomous System (AS) announces a network prefix that it does not own, effectively stealing the traffic meant for the legitimate owner. By setting an alert that triggers when a monitored prefix is seen originating from an Autonomous System Number (ASN) that is not the expected authorized ASN (in this case, AS 1234), ThousandEyes provides immediate notification of a routing takeover.
Identifying this via BGP Origin alerts is superior to simple connectivity checks because it catches the issue at the routing control plane.
* DNS Issues (Options B and D): These involve the translation of names to IPs and would be detected via DNS-specific tests rather than BGP Origin checks.
* Route Poisoning (Option A): This is a generic term often referring to the manipulation of distance- vector protocol metrics to make a route unreachable; while related to routing, BGP Origin checks are the specific tool for detecting external prefix hijacks.
By monitoring the ASN origin, network engineers can quickly distinguish between a local ISP outage and a global security event where their traffic is being misdirected to an illegitimate network.
