An engineer must configure HSRP group 300 on a Cisco IOS router. When the router is functional, it must be the active HSRP router. The peer router has been configured using the default priority value.

Question

Options

• Astandby version 2
• Bstandby 300 priority 110
• Cstandby version 2
• Dstandby 300 priority 90

• A
  94% (31)
• B
  3% (1)
• C

Explanation

HSRP Group 300 Configuration Explanation

Option A is correct because it combines standby version 2 (required to support group numbers above 255, such as group 300) with standby 300 priority 110 (which exceeds the default priority of 100, ensuring this router wins the active role). Without HSRP version 2, group 300 cannot even be configured, since version 1 only supports groups 0–255.

Option B fails because it includes only standby 300 priority 110 without standby version 2 - the router would reject group 300 entirely under version 1. Option D is doubly wrong: it still lacks standby version 2, and a priority of 90 is below the peer's default priority of 100, meaning this router would become standby, not active. Option C (if it appeared as a standalone answer with only standby version 2 and no priority command) would fail because without a priority above 100, this router wouldn't guarantee winning the active election.

Memory Tip: Think "High group = High version" - any HSRP group number over 255 demands version 2, and to win active status you need a priority higher than the default 100 (e.g., 110).
