350-401 Practice Question: Which two statements about IP SLA with object…
Which two statements about IP SLA with object tracking are true? (Choose two.)
⚠ Common exam trap
350-401 often tests the dependency order: the IP SLA operation must be configured before the tracking object, and candidates may mistakenly think the tracking object can be created first.

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A tracking object can monitor the state of an IP SLA operation and change state when the operation fails.
Option A is correct because a track object tied to an IP SLA operation (via 'track 1 ip sla 1 reachability' or 'state') polls that operation's return code and transitions the object between Up and Down when the probe fails or recovers, which is the core purpose of IP SLA object tracking. Option B is correct because the 'track' command creates the tracking object and references the IP SLA operation by its operation number (for example, 'track 1 ip sla 1'), linking the tracker to that specific probe. Option C is wrong because tracked objects can be referenced by static routes, policy-based routing, HSRP/VRRP, and dynamic routing protocols such as EIGRP or OSPF to influence their behavior. Option D is wrong because the tracking object only changes its own Up/Down state and notifies clients; it does not itself edit the routing table, since the referencing route or protocol must be configured to react to the tracker. Option E is wrong because the IP SLA operation must already exist before the tracking object can reference it by number, so the operation cannot be configured afterward.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
A tracking object can monitor the state of an IP SLA operation and change state when the operation fails.
Why this is correct
The tracker polls the referenced IP SLA operation's return code and transitions between up and down accordingly, so downstream features react to probe failure. This satisfies the stem's requirement that a tracking object monitor operation state and change state on failure.
- ✓
The 'track' command is used to create a tracking object that references an IP SLA operation by its operation number.
Why this is correct
The track command instantiates an object whose sole job is to watch something else; pointing it at an IP SLA operation number links that probe's reachability result to the tracker. This satisfies the stem's requirement that tracking reference an operation by its number.
- ✗
Object tracking can only be used with static routes, not with dynamic routing protocols like EIGRP or OSPF.
Why it's wrong here
Object tracking integrates with static routes and with dynamic routing protocols such as EIGRP and OSPF, so restricting it to static routes is false. It is tempting because static route tracking is the most common example, but dynamic protocol tracking is equally supported.
- ✗
The tracking object automatically modifies the routing table when the IP SLA operation fails.
Why it's wrong here
The tracking object reports state changes to the client that references it; it does not itself edit the routing table. It is tempting because tracking influences routing, but the referencing static route or protocol performs the withdrawal, not the tracker.
- ✗
An IP SLA operation can be configured after the tracking object that references it.
Why it's wrong here
Incorrect because the tracking object requires the IP SLA operation to exist first; otherwise, the tracker will be in an error state.

Routing Protocol Comparison
| Protocol | Metric | Max Hops | Algorithm | Type |
|---|---|---|---|---|
| RIP v2 | Hop count | 15 | Bellman-Ford | Distance vector |
| OSPF | Cost (bandwidth) | Unlimited | Dijkstra (SPF) | Link state |
| EIGRP | Composite metric | Unlimited | DUAL | Hybrid |
| IS-IS | Cost | Unlimited | Dijkstra | Link state |
| BGP | Policy / attributes | Unlimited | Path vector | Path vector |
RIP's 15-hop limit makes it unsuitable for large networks. OSPF and EIGRP dominate modern enterprise deployments.

Key term
IP SLA
IP SLA (Service-Level Agreement) is a Cisco feature that actively monitors network performance by generating and measuring synthetic traffic between devices.
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.
