Wch info not incld in the routg table? (Sc)
Source address
2
If a device discovers the root to 10.0.0.0/30 using both the Dynamic routing ospf and static routing protocol which of the following situations occurs? (sc)
add the routes discovered by ospf to the routing table
3
When a router receives a bracket with the destination address 10.1.1.1, which of the following entries can match the destination address?
0.0.0.0 / 0, 10.1.1.0 / 24, 10.1.1.0 / 30
4
Is a device learns the route with the mask of 10.1.1.0 / 24 through osbf and the route with the mask of 10.1.1.0 / 30 to a static route the route adds the two routes to the routing table
true
5
Ospf n is-is are both internal Gateway protocols and Link state protocols
true
6
How does a router select the optimal route? 1. Compare metric cost 2. Compare longest match route entries 3. compares preferences of routes
2, 3,1
7
The route first compares preferences of routes. The route with the lowest preference value is selected as the optimal route. If the routes have the same preferences the route the compares their metrics. If the route has the same metric they are installed in the IP routing table as equal cost routes.
true
8
Can dynamic rooting protocols automatically adapt to changes in network topology
true
9

10
In the network shown in the figure below communicate with router a and router B's look back zero to static routing, you need to enter the following command on router A? (Sc) RTA 10.0.12.1 / 24 rtb 10.0.12.2 / 24 loop back0 10.0.2.2 / 32
IP routes static 10.0.2.2 255.255.255.255 10.0.12.2
11
Which of the following are the basic parameters for configuring static routes (mc)
destination network, the IP address of the next hope, out interface
12
What are the three sources from which throughout the obtains route entries
static routes, dynamic routing, direct routing
13
The classic network forwarding method is based on routing table forwarding. The forwarding method of one flow switch is based on floor table forwarding, for these two forwarding methods, which is correct (mc)
the routing table is fixed length. a device can have only one common routing table, the the route table is matched by matching the destination c i d r segment route with the longest mask
14
The following description is correct (mc)
routes obtain through different routing protocols have different priorities, the metric defined by different routing protocols are not comparable
15
Which of the following are routing protocols (mc)
bgp, o s p f
16
On the serial interface you can configure static routes by specifying either or next hop address or an outgoing interface
true
17
When you configure static routes on broadcast interface, you must specify the next hop address
true
18
For multiple paths to the same destination network, the router needs to compare the size of the cost value to select and if the cost value is the same, it will be selected according to the size of the preference value
false
19
For multiple pass to the same destination network the route the needs to compare the size of the preference value to make a selection and if the preference is the same select according to the size of the cost value
true
20
Which of the following attributes cannot be used as a parameter to measure cost
sysname
21
Referring to the output shown in the figure you can determine that the routing table of the router consists of direct routes and static routes
true
22
When the router receives a packet with a destination IP address of 9.1.1.1 the router forwards it according to the route of 9.1.0.0 / 16 because the mass length of the route is longer
true
23
Which of the following commands of configuring the default route is correct (sc)
(Huawei) IP routes static 0.0.0.0 0.0.0.0 192.168.1.1
24
Which of the following statements about static routing in Huawei equipment is incorrect (sc)
when the priority of a static route is zero, the route will definitely be preferred
25
On the vrp platform what is the order of the default protocol priorities of direct routes, static routes, RIP, and ospf intra area routes from High to low (sc)
