A company uses VoIP between two sites. The network team wants to monitor one-way delay and jitter on the WAN link and automatically switch to a backup link if jitter exceeds a threshold. What should be configured on the router?

Flexible NetFlow with a flow record capturing jitter metrics and a tracked static route

IP SLA TCP connect operation, a tracking object, and a tracked static route

IP SLA ICMP echo operation, a tracking object, and a tracked static route

IP SLA UDP jitter operation, a tracking object with a threshold condition, and a tracked static route

A network engineer is setting up failover for a video conferencing service. The requirement is to use the backup link if the one-way delay exceeds 150 ms OR the jitter exceeds 20 ms. The engineer has configured two IP SLA UDP jitter operations and two tracking objects. However, the backup link is not being used even when both thresholds are exceeded. What is the most likely cause?

The tracking list is using boolean AND instead of OR

The tracking list is using boolean OR instead of AND

The IP SLA operations are not configured with a threshold

The tracking objects are referencing the same SLA operation

An administrator needs to verify that a web server's TCP port 443 is responding and measure how long it takes to establish a connection. The result should be used to influence a route only if the service is down. What should be configured?

IP SLA ICMP echo operation, a tracking object, and a tracked static route

IP SLA TCP connect operation, a tracking object, and a tracked static route

IP SLA UDP jitter operation, a tracking object, and a tracked static route

Flexible NetFlow with a flow record for TCP flags and a tracked static route

A router has an IP SLA ICMP echo operation configured to monitor a remote server. The engineer wants to use the SLA result to influence a static route. What must be configured to link the SLA operation to the route?

A policy-based routing rule that uses the SLA operation

A Flexible NetFlow exporter that sends SLA data to the routing process

A route map that matches the IP SLA operation ID

A tracking object that references the IP SLA operation, then use the tracking object in the static route

A network engineer wants a backup route to be used only if BOTH the primary WAN link (tracked by interface state) AND the ISP gateway (tracked by IP SLA ICMP echo) are down. What should be configured?

Create two tracking objects and a tracking list with boolean AND, then reference the list in the static route

Use a route map with two match clauses and a static route

Create a single tracking object that monitors both conditions using a threshold

Create two tracking objects and a tracking list with boolean OR, then reference the list in the static route

Part of the Infrastructure Security and Services domain, which accounts for 15% of the CCIE-ENTERPRISE-INFRASTRUCTURE exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~8–12 in this domain), expect 1–2 from this objective — we provide 34 practice questions to prepare you well beyond it.
