✍️ 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 Cisco's three-tier campus network model, which layer provides high-speed packet switching between distribution blocks?
The core layer provides fast, reliable transport between distribution layer blocks and should not perform packet manipulation to maintain speed.
3. Which EtherChannel negotiation protocol is Cisco proprietary?
Port Aggregation Protocol (PAgP) is Cisco's proprietary protocol for negotiating EtherChannel link bundles, whereas LACP is the IEEE 802.3ad standard.
4. 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.
5. What does the 'ip helper-address' command accomplish on a Cisco router?
The ip helper-address command converts UDP broadcasts (including DHCP discover packets) into unicast packets forwarded to the specified server address.
6. (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.
