What is a characteristic of Layer 3 MPLS VPNs?

1. A. LSP signaling requires the use of unnumbered IP links for traffic engineering.
2. B. Traffic engineering supports multiple IGP instances
3. C. Traffic engineering capabilities provide QoS and SLAs.
4. D. Authentication is performed by using digital certificates or preshared keys.

Correct Answer: C

MPLS traffic engineering supports only a single IGP process/instance
The MPLS traffic engineering feature does not support routing and signaling of LSPs over unnumbered IP links.

A network administrator performed a Compact Flash Memory upgrade on a Cisco Catalyst 6509 Switch. Everything is functioning normally except SNMP, which was configured to monitor the bandwidth of key interfaces but the interface indexes are changed. Which global configuration resolves the issue?

1. A. snmp-server ifindex permanent
2. B. snmp ifindex permanent
3. C. snmp-server ifindex persist
4. D. snmp ifindex persist

Correct Answer: C
The SNMP ifIndex persistence feature provides an interface index (ifIndex) value that is retained and used when the router reboots. The ifIndex value is a unique identifying number associated with a physical or logical interface. In the following example, SNMP ifIndex persistence is enabled for all interfaces:
router(config)# snmp-server ifindex persist
