NEW QUESTION # 390
[Security, Automation, and Policy Integration in Design] What is a key benefit of Infrastructure as Code (IaC)?
Answer: A
Explanation:
#Explanation:
* D: Repeatable deployments are one of the core benefits of IaC. It allows infrastructure to be provisioned consistently every time using version-controlled templates.
Incorrect options:
* A: Declarative pipelines relate more to CI/CD processes than directly to IaC.
* B: IaC helps prevent configuration drift, but drift itself is a problem-not a benefit.
* C: Agent monitoring is a function of monitoring tools, not IaC.
NEW QUESTION # 391
Which issue poses a challenge for security architects who want end-to-end visibility of their networks?
Answer: C
NEW QUESTION # 392
Refer to the exhibit. The network experiences Stuck-in-Active (SIA) problems due to resource contention. An acquisition will further increase routing demands via R3 and R4.
Which solution best mitigates the SIA issue?
Answer: A
Explanation:
# Explanation:
* C: Configuring R5 and R6 as EIGRP stub routers reduces query scope and prevents SIA conditions.
EIGRP stub routers do not forward queries and are ideal for spoke or edge routers.
Other options:
* A: Load balancing doesn't reduce control-plane query overhead.
* B: Route Flap Dampening isn't applicable to EIGRP and won't solve SIA.
* D: Default route advertisement helps simplify routing, but stub configuration is purpose-built to prevent SIA issues.
NEW QUESTION # 393
Which aspect of BGP-LS makes it scalable in large networks when multiarea topology information must be gathered?
Answer: B
Explanation:
BGP-LS (BGP Link-State) distributes IGP topology information using BGP. When used in multi-area or multi-domain networks, BGP-LS allows for a centralized controller to receive topology information in a scalable way. BGP inherently runs over TCP, which provides reliable, ordered delivery using built-in flow control mechanisms.
The use ofTCP-based flow controlensures that even in large-scale networks where significant link-state information is exchanged, the flow of data between BGP peers remains efficient, controlled, and buffered according to the receiver's capacity. This makes it ideal for transporting massive amounts of LS data across wide areas and into SDN controllers for applications like traffic engineering or path computation.
Why other options are incorrect:
* A, B, and C refer to mechanisms that are not implemented or leveraged by BGP.
* TCP-based flow control is the only valid flow-control mechanism used in BGP sessions.
