✍️ Sample Cisco ENCOR Questions & Answers
1. What command parameter can be changed to encrypt data traffic?
The security model command set can be configured to enable data traffic encryption.
2. In SNMPv3, which security level provides both authentication and encryption?
The authPriv security level uses HMAC for authentication and DES/AES for privacy (encryption) of SNMP messages.
3. (3) instructions to clear the NVRAM's data.
All three commands—`write erase`, `erase startup-config`, and `erase nvram:`—effectively clear the startup configuration stored in Non-Volatile RAM (NVRAM) on a Cisco device. `write erase` is a legacy command, while `erase startup-config` is a more explicit and modern command for the same purpose. `erase nvram:` directly targets the NVRAM file system to remove the startup configuration, often done to reset a device to its factory default settings.
4. What does the BGP `neighbor next-hop-self` command accomplish?
`next-hop-self` causes the router to substitute its own IP address as the BGP next-hop when advertising routes to iBGP neighbors, resolving next-hop reachability issues common in iBGP.
5. Which LSA type is generated by an ASBR to advertise external routes into the OSPF domain?
Type 5 AS External LSAs are originated by ASBRs and flooded throughout the entire OSPF domain except into stub areas.
6. ______ handles label swapping and transfers data based on L3 or L2 information.
The data plane, also known as the forwarding plane, is responsible for the actual forwarding of packets based on the information established by the control plane. In MPLS, the data plane performs label swapping and transfers data packets using the Label Forwarding Information Base (LFIB), which maps incoming labels to outgoing labels and interfaces, enabling high-speed packet delivery.
