Selected Answer: D "for the IP address of GigabitEthernet0/0/0"

Selected Answer: D If we're after the destination subnet mask then I pick D 255.255.255.255

I choose Answer B. Because the IP range of the routing path for 172.16.2.0/23 is 172.16.2.0 to 172.16.3.255 The packet destination IP 172.16.3.254 is the last available IP within this range. If the CIDR notation is /23, the subnet mask should be 255.255.254.0

Selected Answer: D Destined for the IP address of GigabitEthernet0/0/0 and the IP address of G0/0/0 is 10.10.10.3/32

Selected Answer: D * destined for the IP address of GigabitEthernet0/0/0 * Ip address of the router /32 local route

When you check the routing table, code C means connected network, the network that the interface is connected to. Code L points to the IP address of the interface that the network is connected to. If the IP address of the interface connected to network 10.10.10.0 is 10.10.10.3, then the subnet of that interface has to be /32. So D.

The answer is C. Mask /32 is for the local address of the router. The destination subnet mask is /24.

Selected Answer: D This test has turned into a grammar test instead of a technical one. The interface gi0/0/0 is directly connected and the subnet mask is /32 so the subnet has to be 255.255.255.255.

Selected Answer: C The packet comes from 172.16.3.254. It is headed to the IP address of GigabitEthernet0/0/0, which maps to the network 10.10.10.0/24, as shown in the routing table: C 10.10.10.0/24 is directly connected, GigabitEthernet0/0/0. L 10.10.10.3/32 is directly connected, GigabitEthernet0/0/0 (the specific IP on that interface). This shows that GigabitEthernet0/0/0 belongs to the 10.10.10.0/24 network. So, the subnet mask of the destination route is: C. 255.255.255.0, which matches a /24 network.

Selected Answer: D It is D because "Note that the router also automatically produces a different kind of route, called a local route. The local routes define a route for the one specific IP address configured on the router interface. Each local route has a /32 prefix length, defining a host route, which defines a route just for that one IP address. For example, the last local route, for 172.16.5.1/32, defines a route that matches only the IP address of 172.16.5.1. Routers use these local routes that list their own local IP addresses to more efficiently forward packets sent to the router itself." (CCNA official Cert, p. 378)

Selected Answer: C C. 255.255.255.0 Here's why the other options are wrong: A. 0.0.0.0: This is the default subnet mask for Class A networks, but it's not relevant here. The routing table shows specific subnet masks for each route. B. 255.255.254.0: This subnet mask could be used on a network, but it doesn't match the subnet mask in the routing table for the destination route. D. 255.255.255.255: This is a /32 subnet mask, which makes a single-host network. It's unlikely to be used for a GigabitEthernet interface connecting to another network.

Selected Answer: C tricky question

C is the right answer because the question asks : What is the subnet mask of the destination? Local is for the local equipment, Connected is for the subnet. The right line to use in the Route Table is where you see 10.10.10.0/24. The mask is 255.255.255.0

You're definitely right because it says "is destined for the lP address of GigabitEthernet0f0f0" so the only mask for one host is /32 so the answer D (255.255.255.255) should be good.

Selected Answer: C Closed mask /32 is not the "connected" subnet (just a "local" host), in this case the interface g0/0/0 has the following configuration: (config-if)# ip add 10.10.10.3 255.255.255.0. Do not be confused, because in the "#show ip route" output, the "Local" ip address (L) will always be shown with a closed mask (255.255.255.255), but the "Connected" network (C) will show the subnet. If asked which host mask would be /32, but the subnet mask is /24.

We don't know if the destination route points to the subnet or the host, but even if the route pointed straight to the host (/32), that's just the configuration, /32 is not viewed as a subnet, just a local host. If 10.10.10.3 /32 were a subnet then what would its broadcast address be?

the correct answer is C after ios 15 : we have both Connected(C) route and Local(L) route. Connected route: network address with network subnet mask Local route: the interface address, so we do not need to use "sh ip int br" to check. The subnet mask is always 32 bit, since it is a host address. In this case, we are asked about the destination route subnet mask, we should check the connected(C) route.

C is correct because, destination is gigabitEthernet 0/0/0 and this interface is configured as /24 , which is 255.255.255.0

After thinking it over the answer should be "D. 255.255.255.255" like I wrote just before for " 593554d "

Selected Answer: C so C is for connected meaning the 10.10.10.0/24 is the NETWORK addresss The is LOCAL 10.10.10.3/32 the IP on the interface and /32 it's a HOST ROUTE . The right answer is 255.255.255.0 C this is the subnet mask for the destination network.
