A company runs a critical database service on a server. The network team wants to automatically switch to a backup path if the database service (TCP port 1521) becomes unavailable. What should be configured?

IP SLA UDP jitter to the server, a tracking object, and a tracked static route

IP SLA ICMP echo to the server, a tracking object, and a tracked static route

IP SLA TCP connect to port 1521, a tracking object, and a tracked static route

Flexible NetFlow to monitor traffic to port 1521 and a tracked static route

An ISP needs to provide customers with detailed traffic statistics, including source/destination IP, ports, and protocol. They want to export this data to a central collector. What should be configured on the edge routers?

Flexible NetFlow with a flow record containing IP, port, and protocol fields, a flow exporter, and a flow monitor

A tracking object for each customer interface

IP SLA ICMP echo to each customer

A simple SNMP poll of interface counters

A network administrator is troubleshooting a performance issue where users report slow access to a cloud application. The router has Flexible NetFlow enabled. What is the most effective way to identify the cause?

Check the tracking object status for the application server

Run an IP SLA UDP jitter operation to the application server

Analyze NetFlow data for high latency flows to the application's IP addresses

Use a tracking list to combine interface states

A network engineer is configuring a dual-homed site with two ISPs. The primary ISP is preferred, but the backup should be used only if the primary ISP's gateway is unreachable AND the primary ISP's DNS server (8.8.8.8) is also unreachable. The engineer has created two IP SLA ICMP echo operations. What is the correct configuration to achieve this?

Create two tracking objects, each referencing one SLA, then a tracking list with boolean AND, and use the list in the static route

Create two tracking objects and use them directly in the static route

Create a single tracking object that references both SLAs

Create two tracking objects, each referencing one SLA, then a tracking list with boolean OR, and use the list in the static route

A VoIP deployment requires failover to a backup link if jitter exceeds 30 ms OR packet loss exceeds 2% on the primary link. The engineer has configured two IP SLA UDP jitter operations. However, the backup link is being used too often. What is the most likely cause and solution?

The tracking object is monitoring the wrong SLA; correct the SLA reference

The tracking list is using boolean OR instead of AND; change it to AND

The tracking list is using boolean AND instead of OR; change it to OR

The IP SLA thresholds are set too low; increase the thresholds
