Read the first 7 Network Design & Optimization flashcards as text

  1. A telecom engineer observes high packet loss on a fiber link after a storm. Which diagnostic step should be performed FIRST?

    Answer: Run an OTDR test to locate the fault

    An Optical Time Domain Reflectometer (OTDR) test pinpoints the exact location and nature of a fiber fault without requiring physical cable access.

  2. Which network design principle minimizes the blast radius of a failure by dividing large Layer 2 domains?

    Answer: VLAN segmentation

    VLANs create separate broadcast domains, so a broadcast storm or failure in one VLAN does not propagate to others.

  3. A company's WAN link is at 95% utilization. Before purchasing more bandwidth, which optimization should be evaluated first?

    Answer: Implement WAN optimization with data deduplication and compression

    WAN optimization technologies like deduplication and compression can reduce effective traffic volume by 50–80%, often deferring costly bandwidth upgrades.

  4. In BGP, what is the effect of prepending your own AS number multiple times to an advertised prefix?

    Answer: Makes the path appear longer to external peers, discouraging inbound traffic via that path

    AS path prepending artificially lengthens the AS path, causing external BGP peers to prefer shorter paths via other providers.

  5. Which technology is used to aggregate multiple physical links into a single logical high-bandwidth connection between switches?

    Answer: Link Aggregation Control Protocol (LACP)

    LACP (IEEE 802.3ad) dynamically negotiates and maintains link aggregation groups, combining bandwidth and providing redundancy.

  6. A network manager needs to ensure that a mission-critical application receives guaranteed bandwidth regardless of other traffic. Which QoS mechanism is MOST appropriate?

    Answer: Committed information rate (CIR) with guaranteed queuing

    A guaranteed queue backed by a CIR reserves a minimum amount of bandwidth for the application even during periods of network congestion.

  7. What is the purpose of route summarization (route aggregation) in a large enterprise network?

    Answer: To reduce routing table size and control update propagation

    Summarizing multiple specific routes into a single aggregate prefix reduces routing table size, conserves memory, and limits the propagation of topology changes.
