CCNP Switch FAQ: Monitoring Performance with IP SLA
Q1. Is the following statement true or false? To use the IP SLA feature, a third-party network management platform must be used.
Q2. Which of the following are valid types of IP SLA tests? (Choose all that apply.)
a. ICMP echo
b. ICMP time exceeded
c. UDP jitter
d. UDP connect
e. TCP jitter
f. TCP connect
Q3. Which one of the following commands will enable a switch to participate in all types of IP SLA tests?
a. ip sla enable
b. ip sla all
c. ip sla reflector
d. ip sla responder
e. ip sla reply all
Q4. Suppose the following configuration commands have been entered on Switch A, which has IP address 10.1.1.1. Which one of the answers correctly identifies the configuration that is needed on the target switch so it can participate in the UDP jitter tests?
ip sla 40132
udp-jitter 10.9.1.100 17000 source-ip 10.1.1.1 num-packets 100
ip sla schedule 40132 life forever start-time now ageout 3600
a. Enter the same set of commands on the target switch.
b. Enter theip sla responder command on the target switch.
c. Do nothing; the target switch will automatically participate.
d. Do nothing; UDP jitter is not a valid IP SLA test.
Q5. To verify that an IP SLA test operation 123 has been configured and is scheduled to run, which one of the following commands should you use?
a. show ip sla status 123
b. show ip sla configuration 123
c. show ip sla operation 123
d. show ip sla 123
Q6. According to the following output, how many IP SLA tests have run and gotten
results? (Choose one answer.)
