EIGRP (CCNP) Practice Questions

EIGRP DUAL, feasibility condition, stub routing, and named mode at CCNP depth.

One solved question, so you can see how these are marked

In EIGRP, what condition must an advertised path meet to satisfy the Feasibility Condition and become a Feasible Successor?

Its Reported Distance (RD) must be strictly less than the route's stored Feasible Distance (FD).

To guarantee a loop-free path, EIGRP requires that a neighbor's Reported Distance (RD, also called Advertised Distance) be strictly smaller than the local Feasible Distance (FD), the lowest metric the router has had to the destination since the route last went passive.

Every question in the set below is marked like this. The answers stay hidden until you pick one.

All 13 EIGRP (CCNP) questions in this set

Answers and explanations appear when you work through the set above.

  1. What are the default K-values enabled in EIGRP for metric computation?

    • K1=1, K2=1, K3=1, K4=0, K5=0
    • K1=1, K2=0, K3=1, K4=0, K5=0
    • K1=0, K2=1, K3=0, K4=1, K5=1
    • K1=1, K2=1, K3=0, K4=0, K5=0

  2. A remote branch router is configured with eigrp stub connected summary. Which routes will this router advertise to its EIGRP neighbors?

    • Only directly connected networks and summarized routes.
    • Connected, redistributed static, and summary routes.
    • All routes in its routing table, including EIGRP-learned routes.
    • Only summary routes.

  3. What enhanced capability does EIGRP Named Configuration Mode introduce over traditional autonomous-system configuration mode?

    • Wide 64-bit metrics and one hierarchy for IPv4, IPv6 and VRF address families.
    • Replacement of the DUAL algorithm with the Bellman-Ford algorithm for faster convergence.
    • Elimination of dynamic neighbor discovery in favor of statically defined neighbor statements.
    • Mandatory IPsec protection of all EIGRP packets exchanged between neighbors.

  4. What IP address source is automatically utilized as the Next-Hop address for dynamic routing protocols (OSPFv3, EIGRP for IPv6) operating over an IPv6 network interface?

    • Global Unicast Address (GUA)
    • Unique Local Address (ULA)
    • Link-Local Address (FE80::/10)
    • All-EIGRP-routers multicast (FF02::A)

  5. What formula defines the Feasibility Condition in EIGRP for selecting a Feasible Successor?

    • Reported Distance (RD) must be strictly less than the Feasible Distance (FD).
    • Reported Distance (RD) must be equal to or greater than the Feasible Distance (FD).
    • Feasible Distance (FD) must equal 0.
    • Calculated Metric must be less than 100.

  6. What command configures an EIGRP router to advertise only directly connected networks while suppressing all internal EIGRP routes?

    • eigrp stub receive-only
    • eigrp stub connected
    • eigrp stub static
    • eigrp stub summary

  7. Which two composite metric components are enabled by default (K1=1, K3=1) in EIGRP path cost calculation?

    • Bandwidth and Delay
    • Load and Reliability
    • MTU and Hop Count
    • Delay and Jitter

  8. What routing table entry is automatically created on a router performing manual EIGRP route summarization to prevent routing loops for unassigned subnets within the summary block?

    • A default route pointing out the router's local WAN interface.
    • A local discard route to Null0 for the summary prefix.
    • A static route pointing to the configured default gateway.
    • An IP SLA probe that monitors the summarizing egress interface.

  9. Which two path attributes are used by default in the EIGRP metric calculation (K1=1, K2=0, K3=1, K4=0, K5=0)?

    • Minimum Bandwidth and Cumulative Delay
    • Hop Count and Interface MTU
    • Link Reliability and Average Interface Load
    • Interface Packet Loss and Jitter

  10. Under what mathematical condition does an EIGRP neighbor qualify as a Feasible Successor for a destination prefix?

    • Its Reported Distance (RD) is strictly less than the route's current Feasible Distance (FD).
    • Its Feasible Distance (FD) equals the local router's administrative distance for internal EIGRP (90).
    • Its Reported Distance (RD) is equal to its hop count to the destination network.
    • Its path metric is higher than the successor's, proving the path is a different route.

  11. Which EIGRP stub option configures a branch router to advertise only directly attached connected networks while suppressing summary and internal EIGRP routes?

    • eigrp stub receive-only
    • eigrp stub connected
    • eigrp stub summary
    • eigrp stub static

  12. Which subconfiguration mode block is used in EIGRP Named Mode to configure interface-level parameters like hello intervals or authentication keys?

    • af-interface <interface-id>, inside the address-family block
    • topology base, inside the address-family block
    • line vty 0 4, under global configuration
    • ip authentication mode eigrp <as> md5, under the physical interface

  13. Which multicast IP address is used by EIGRP for IPv4 to send Hello and Update packets to neighboring routers?

    • 224.0.0.5
    • 224.0.0.9
    • 224.0.0.10
    • 224.0.0.102
