Free Cisco CCNP Enterprise core (ENCOR 350-401) practice questions

Sample question 1. An SXP peering between two switches worked until one engineer entered cts sxp default password on switch A only. The connection now fails to come up. What is the most likely cause?

1. The password exceeds the 32-character limit, so switch A rejects the SXP connection entirely
2. SXP supports only TCP-AO, so a plain default password cannot be negotiated with a peer
3. Switch B still has no password, and both peers must use the same one for the SXP connection to authenticate
4. The speaker must hold the password and the listener must have none, so switch B has to clear its value

Sample question 2. In a looped Layer 2 access design, VLAN 30 has its spanning tree root on distribution switch D2, while HSRP active for VLAN 30 is D1. Interface counters show heavy VLAN 30 traffic crossing the D1-D2 link, and the access uplink to D1 is blocking for VLAN 30. Which design change follows best practice?

1. Make one distribution switch both STP root and HSRP active for VLAN 30, along with the PIM DR role
2. Raise the spanning tree cost on the access uplink to D2, so that the uplink to D1 forwards instead
3. Replace HSRP with VRRP, because a VRRP backup router also forwards traffic for the virtual MAC address
4. Enable PortFast on the access uplinks so that both uplinks forward and traffic takes the direct path

Sample question 3. A new team member asks what a YANG module is. Which description is accurate?

1. A transport protocol that carries configuration changes between a management station and a device
2. The structure and constraints of configuration data, state data, RPCs and notifications
3. A scripting language that runs on the device to apply configuration when an event occurs
4. A text format for saving a device startup configuration so that it can be restored later
