Refer to the exhibit. Which route type does the routing protocol Code D represent in the output?
Answer: B
That's a good way to recognize it, but the proper answer would be: because EIGRP uses the DUAL (D) algorithm to perform its calculations.

Using direct sequence spread spectrum, which three 2.4-GHz channels are used to limit collisions?
Answer: C
In the 2.4 GHz frequency band, the three channels that are commonly used to limit collisions when using direct sequence spread spectrum (DSSS) are channels 1, 6, and 11. These channels are spaced far enough apart in the spectrum to minimize the likelihood of interference between devices operating on different channels. DSSS is a spread spectrum technique that is used to reduce the impact of interference on wireless communication. It involves spreading the data signal over a wide frequency band by modulating the data with a high-frequency code, or "chipping" code. This chipping code is used to spread the signal over a wide frequency range, making it less vulnerable to interference and more resistant to noise. By using DSSS and selecting channels 1, 6, and 11, it is possible to limit collisions and improve the performance of the wireless network. It's important to note, however, that other factors, such as the number of devices on the network, the type of devices, and the distance between devices, can also impact the performance of the network and may require additional strategies to optimize network performance.

An engineer must configure an OSPF neighbor relationship between router R1 and R3. The authentication configuration has been configured and the connecting interfaces are in the same 192.168.1.0/30 subnet. What are the next two steps to complete the configuration? (Choose two.)
Answer: AB
Ospf isn't active on the interfaces until you configure both interfaces to be inside of area 0 which you do with the network xxxx xxxx area 0 statement inside the ospf process or by using "ip ospf area 0" inside the interface configuration

Refer to the exhibit. A packet is being sent across router R1 to host 172.16.0.14. What is the destination route for the packet?
Answer: D
D is Right, it’s use the default route since there is no entry for the destination address/subnet entry in the routine table.

Refer to the exhibit. A packet is being sent across router R1 to host 172.16.3.14. To which destination does the router send the packet?
Answer: D
Routers prefer routes with the "longest match". Meaning the smallest prefix that contains the host's IP address. /28 is a longer match than /24. D is correct.

Refer to the exhibit. Router R2 is configured with multiple routes to reach network 10.1.1.0/24 from router R1. Which path is chosen by router R2 to reach the destination network 10.1.1.0/24?
Answer: A
Admin Distance: Connected - 0 Static - 1 eBGP - 5 iEIGRP - 90 OSPF - 110 IS-IS - 115 RIP - 120 So yeah answer is correct based from AD of a statically configured route.

Refer to the exhibit. What is the next hop address for traffic that is destined to host 10.0.1.5?
Answer: D
Correct Answer D. Question asks what is the next hop address. Multiple routes are inserted into the router already, so now we look for the highest prefix. A /32 prefix represents a host, and this is the highest you can get with ipv4. The next hop is 10.0.1.50 as you can see where it says 'via 10.0.1.50'.

Refer to the exhibit. A network administrator assumes a task to complete the connectivity between PC A and the File Server. Switch A and Switch B have been partially configured with VLANs 10, 11, 12, and 13. What is the next step in the configuration?
Answer: B
They are not on different subnets. Subnet 192.168.0.0 /23 has 2^9 = 512 hosts, which spans an IP range of 192.168.0.0 - 192.168.1.255. Addresses 192.168.0.10 and 192.168.1.20 are on the same range and their respective interfaces are on the same VLAN. The only problem here is that the trunk link on Switch A doesn't allow VLAN 13, so "B" is correct.

DRAG DROP - A network engineer is configuring an OSPFv2 neighbor adjacency. Drag and drop the parameters from the left onto their required categories on the right. Not all parameters are used. Select and Place:
This is an interactive task on the real exam — a drag-and-drop, hotspot or ordering question. There is nothing to select here, so the answer is shown below for reference.
Answer: See figure below
From the perspective of OSPF, there are a couple of things that must match for a OSPF neighborship to establish; these include: The devices must be in the same area The devices must have the same authentication configuration The devices must be on the same subnet The devices hello and dead intervals must match The devices must have matching stub flags https://www.expertnetworkconsultant.com/configuring/ospf-neighbor-adjacency/ So: Must Match: Area ID, NetMask, Timers Must have Unique: IP Address, Router ID "The OSPF process-id is a numeric value local to the router. It does not have to match process-ids on other routers." http://cisco2960.over-blog.com/2014/01/cisco-ospf-process-id.html

R1 has learned route 192.168.12.0/24 via IS-IS, OSPF, RIP, and Internal EIGRP. Under normal operating conditions, which routing protocol is installed in the routing table?
Answer: B
With the same route (prefix), the router will choose the routing protocol with lowest Administrative Distance (AD) to install into the routing table. The AD of Internal EIGRP (90) is lowest so it would be chosen. The table below lists the ADs of popular routing protocols. Note: The AD of IS-IS is 115. The ג€EIGRPג€ in the table above is ג€Internal EIGRPג€. The AD of ג€External EIGRPג€ is 170. An EIGRP external route is a route that was redistributed into EIGRP.
