Cisco Implementing Cisco Enterprise Network Core Technologies (350-401 ENCOR) Sample Questions (Q225-Q230):

NEW QUESTION # 225
Refer to the Exhibit.

An engineer is installing a new pair of routers in a redundant configuration. When checking on the standby status of each router the engineer notices that the routers are not functioning as expected. Which action will resolve the configuration error?

Answer: B

Explanation:
Explanation
From the output exhibit, we notice that the key-string of R1 is Cisco123! (letter C is in capital) while that of R2 is cisco123!. This causes a mismatch in the authentication so we have to fix their key-strings.
key-string [encryption-type] text-string: Configures the text string for the key. The text-string argument is alphanumeric, case-sensitive, and supports special characters.

NEW QUESTION # 228
A wireless client roams from one Access Point to another Access Point using a different switch in a Cisco SD-Access network. If only a single Wireless Lan Controller in involved, what roaming methods is being used?

Answer: A

Explanation:
SDA RoamingSDA supports two additional types of roaming, which are Intra-xTR and Inter-xTR.
In SDA, xTR stands for an access-switch that is a fabric edge node. It serves both as an ingress tunnel router as well as an egress tunnel router.
Intra-xTR
When a client on a fabric enabled WLAN, roams from an access point to another access point on the same access-switch, it is called Intra-xTR. Here, the local client database and client history table are updated with the information of the newly associated access point.
Inter-xTR.
When a client on a fabric enabled WLAN, roams from an access point to another access point on a different access-switch, it is called Inter-xTR.

NEW QUESTION # 229
In a wireless Cisco SD-Access deployment, which roaming method is used when a user moves from one access point to another on a different access switch using a single WLC?

Answer: A

Explanation:
A fabric edge node provides onboarding and mobility services for wired users and devices (including fabric-enabled WLCs and APs) connected to the fabric. It is a LISP tunnel router (xTR) that also provides the anycast gateway, endpoint authentication, and assignment to overlay host pools (static or DHCP), as well as group-based policy enforcement (for traffic to fabric endpoints).
From Cisco's guide, under SDA roaming - When a client on a fabric enabled WLAN, roams from an access point to another access point on a different access-switch, it is called Inter-xTR, like a highway. Intra is within intra is between. Like interstate highways. That's how I remember.
