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

Refer to the exhibit. Router BRDR-1 is configured to receive the 0.0.0.0/0 and 172.17.1.0/24 network via BGP and advertise them into OSPF are 0. An engineer has noticed that the OSPF domain is receiving only the 172.17.1.0/24 route and default route 0.0.0.0/0 is still missing. Which configurating must engineer apply to resolve the problem?

1. A. Option A
2. B. Option B
3. C. Option C
4. D. Option D

Correct Answer: D

What is a TLOC in a Cisco SD-WAN deployment?

1. A. value that identifies a specific tunnel within the Cisco SD-WAN overlay
2. B. identifier that represents a specific service offered by nodes within the Cisco SD-WAN overlay
3. C. attribute that acts as a next hop for network prefixes
4. D. component set by the administrator to differentiate similar nodes that offer a common service

Correct Answer: D
A TLOC is a Transport Locator that represents an attachment point where a Cisco WAN Edge device connects to a WAN transport. A TLOC is uniquely identified by a tuple of three values - (System-IP address, Color, Encapsulation).
A TLOC route consists of all required information needed by a remote peer in order to establish an overlay tunnel with that TLOC. This includes private and public IP addresses and ports, site-id, preference, weight, status, encapsulation info such as encryption and authentication parameters, and much more.
