Which measurement is used from a post wireless survey to depict the cell edge of the access points?

1. A. SNR
2. B. Noise
3. C. RSSI
4. D. CCI

Correct Answer: A
Coverage defines the ability of wireless clients to connect to a wireless AP with a signal strength and quality high enough to overcome the effects of RF interference. The edge of the coverage for an AP is based on the signal strength and SNR measured as the client device moves away from the AP.
The signal strength required for good coverage varies dependent on the specific type of client devices and applications on the network.
To accommodate the requirement to support wireless Voice over IP (VoIP), refer to the RF guidelines specified in the Cisco 7925G Wireless IP Phone Deployment Guide. The minimum recommended wireless signal strength for voice applications is -67 dBm and the minimum SNR is 25 dB.
The first step in the analysis of a post site survey is to verify the ‘Signal Coverage’. The signal coverage is measured in dBm. You can adjust the color-coded signal gauge to your minimum-allowed signal level to view areas where there are sufficient and insufficient coverage. The example in Figure 8 shows blue, green, and yellow areas in the map have signal coverage at -67 dBm or better. The areas in grey on the coverage maps have deficient coverage. Source from Cisco

Which function does a fabric edge node perform in an SD-Access deployment?

1. A. Connects the SD-Access fabric to another fabric or external Layer 3 networks
2. B. Connects endpoints to the fabric and forwards their traffic
3. C. Provides reachability border nodes in the fabric underlay
4. D. Encapsulates end-user data traffic into LISP.

Correct Answer: B
There are five basic device roles in the fabric overlay:
+ Control plane node: This node contains the settings, protocols, and mapping tables to provide
the endpoint-to-location (EID-to-RLOC) mapping system for the fabric overlay.
+ Fabric border node: This fabric device (for example, core layer device) connects external Layer
3 networks to the SDA fabric.
+ Fabric edge node: This fabric device (for example, access or distribution layer device) connects
wired endpoints to the SDA fabric.
+ Fabric WLAN controller (WLC): This fabric device connects APs and wireless endpoints to the
SDA fabric.
+ Intermediate nodes: These are intermediate routers or extended switches that do not provide
any sort of SD-Access fabric role other than underlay services.
