Zorluk: KolayFirst Hop Redundancy Protocols (HSRP and VRRP)

Which two statements accurately describe the default operational characteristics of Cisco Hot Standby Router Protocol version 1 (HSRPv1)? (Select two.)

  1. Preemption is disabled by default on HSRP-enabled interfaces.Cevap
  2. The default interface priority assigned to an HSRP group member is 100.Cevap
  3. C
    The virtual IP address can be configured to match the physical IP address of the active router's interface.
  4. D
    When interface priorities are equal, the router with the lowest physical IPv4 address becomes active.

Cevap

Preemption is disabled by default on HSRP-enabled interfaces, and the default interface priority assigned to an HSRP group member is 100.
The correct options accurately identify default HSRP behavior: preemption is disabled by default so a higher-priority router does not automatically assume the active role, and the default interface priority value is 100.

Adım Adım Çözüm

1
Evaluate default HSRP priority settings
Confirm that Cisco IOS assigns a default priority of 100 to HSRP group interfaces.
Priorities range from 0 to 255, with 100 being the baseline default.
2
Evaluate default HSRP preemption behavior
Confirm that preemption is disabled by default in HSRP.
Without the standby preempt command, a newly booted or recovered router with a higher priority remains in Standby state.
3
Verify virtual IP rules and tie-breaking logic
Identify incorrect statements regarding physical IP reuse and tie-breaker rules.
HSRP virtual IPs must not equal physical interface IPs, and tie-breakers favor the highest IP address.
