Which two statements about HSRP are true? (Choose two.)

Question

Options

• AIts virtual MAC is 0000.0C07.Acxx.
• BIts multicast virtual MAC is 0000.5E00.01xx.
• CIts default configuration allows for pre-emption.
• DIt supports tracking.
• EIt supports unique virtual MAC addresses.

• A
  94% (50)
• C
  4% (2)
• E
  2% (1)

Explanation

HSRP Key Facts Explained

Why A and D are correct: HSRP (Hot Standby Router Protocol) uses the well-known virtual MAC address format 0000.0C07.ACxx, where "xx" represents the HSRP group number in hexadecimal - this is a Cisco proprietary standard you must memorize. HSRP also supports interface tracking, allowing the active router to lower its priority if a tracked interface goes down, enabling a more capable router to take over.

Why the distractors are wrong:

• B is incorrect - 0000.5E00.01xx is the virtual MAC used by VRRP (Virtual Router Redundancy Protocol), not HSRP
• C is incorrect - HSRP does not enable pre-emption by default; it must be manually configured with standby X preempt
• E is incorrect - HSRP uses a fixed/derived virtual MAC based on the group number, not unique arbitrary MAC addresses (that concept is more associated with GLBP)

Memory Tip: Use the phrase "Cisco's Own Creation" to remember that 0000.0C07.AC belongs to HSRP (Cisco proprietary), while VRRP = 5E - think "V for VRRP, V for five-E." For pre-emption, remember: HSRP is passive by default - it won't fight back unless told to!
