350-401 Practice Question: Which two statements about network design for…
Which two statements about network design for high availability are true? (Choose two.)
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
HSRP allows two or more routers to share a virtual IP address, providing default gateway redundancy.
High availability design aims to minimize downtime through redundancy and fast convergence. First Hop Redundancy Protocols (FHRP) like HSRP, VRRP, or GLBP provide default gateway redundancy. StackWise Virtual allows switches to operate as a single logical device, improving redundancy and simplifying management. Option A is correct because HSRP provides active/standby gateway redundancy. Option C is correct because StackWise Virtual virtualizes two switches into one, reducing complexity and improving resilience. Option B is incorrect because HSRP does not provide load balancing by default (GLBP does). Option D is incorrect because a single uplink is a single point of failure; high availability requires redundant links. Option E is incorrect because redundant links without STP or loop prevention would cause broadcast storms; STP is essential.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
HSRP allows two or more routers to share a virtual IP address, providing default gateway redundancy.
Why this is correct
Correct because HSRP enables a group of routers to present a single virtual gateway, with one active and one standby.
- ✗
HSRP automatically load-balances traffic across all routers in the group.
Why it's wrong here
Incorrect because HSRP uses active/standby; load balancing requires multiple groups or GLBP.
- ✓
StackWise Virtual allows two physical switches to operate as a single logical switch for redundancy.
Why this is correct
Correct because StackWise Virtual combines two switches into one control plane, simplifying management and providing link redundancy.
- ✗
A single uplink from an access switch to the distribution layer is sufficient for high availability.
Why it's wrong here
Incorrect because a single uplink is a single point of failure; high availability requires redundant links.
- ✗
Redundant links between switches do not require Spanning Tree Protocol to prevent loops.
Why it's wrong here
Incorrect because redundant links create physical loops; STP is essential to block redundant paths and prevent broadcast storms.

Key term
HSRP vs VRRP vs GLBP
HSRP, VRRP, and GLBP are network protocols that provide high availability by allowing multiple routers to work together as a single virtual router, ensuring that if one router fails, another automatically takes over without disrupting the network.
Key term
First Hop Redundancy Protocol
A First Hop Redundancy Protocol provides automatic backup for the default gateway router on a network so that devices keep working if the primary router fails.
