Ein Netzwerkadministrator muss ein Netzwerk der Klasse B in vier gleich große Subnetze aufteilen, von denen jedes einen Hostbereich von
1.000 Hosts. Welche der folgenden Subnetzmasken sollte der Administrator verwenden?
Correct Answer: A 🗳️
Explanation: Only visible for TroytecDumps members. You can sign-up / login (it's free).
Ein Netzwerktechniker erhält ein Ticket von einem Mitarbeiter, der an PC 1 arbeitet, aber keine Verbindung zum Datenbankserver herstellen kann. Der Techniker versucht, den Datenbankserver von PC 1 aus anzupingen, jedoch tritt ein Timeout auf. Nach Überprüfung der Auslastung von Switch 1 und Switch 2 stellt der Techniker eine hohe CPU-Auslastung fest und beobachtet, dass sich die MAC-Tabelle ständig ändert.
ANWEISUNGEN
Konfigurieren Sie Switch 1 und Switch 2, um das Problem des Mitarbeiters zu beheben. Überprüfen Sie anschließend die Verbindung zwischen den PCs.
1 und dem Datenbankserver.
Switch 1 und Switch 2 befinden sich bereits im Konfigurationsmodus. Geben Sie „help“ ein, um eine Liste der verfügbaren Befehle anzuzeigen.





Correct Answer:
See the solution in Explanation below.
Explanation:
Switch 1
spanning-tree vlan 10 root primary
spanning-tree vlan 20 root secondary
Switch 2
spanning-tree vlan 20 root primary
spanning-tree vlan 10 root secondary
This PBQ is pointing to a switching loop / MAC flapping problem. The biggest clues are the high CPU utilization and the fact that the MAC table is continuously changing. That behavior is classic for a Layer 2 loop when redundant links exist between switches and no proper spanning-tree root role has been established.
The available commands shown in the screenshots are limited to spanning-tree vlan, so this is not an interface shutdown question. The fix is to use STP per VLAN and make one switch the preferred root for one VLAN and the other switch the preferred root for the other VLAN. That prevents both uplinks from forwarding in an uncontrolled loop while still giving redundancy.
A clean design is:
Switch 1 root primary for VLAN 10
Switch 2 root primary for VLAN 20
Make each opposite switch root secondary for failover
That stabilizes Layer 2 forwarding, stops MAC address flapping, reduces CPU load, and restores normal connectivity. After applying the STP root settings, the user should be able to ping 192.168.1.31 from PC 1 successfully. If your simulator asks for validation, run the ping again from PC 1 to the database server.

Correct Answer:
See the solution in Explanation.
Explanation:
To validate routing between networks hosting Workstation A and File Server 2, follow these steps:
Review Routing Tables:
Check the routing tables of Router A, Router B, and Router C to identify any missing routes.
Identify Missing Routes:
Ensure that each router has routes to the networks on which Workstation A and File Server 2 are located.
Add Static Routes:
If a route is missing, add a static route to the relevant destination network via the correct interface.
Routing Table:
Gateway of last resort is 0.0.0.0 to network 0.0.0.0
S* 0.0.0.0/0 is directly connected, GigabitEthernet3
10.0.0.0/8 is variably subnetted, 4 subnets, 2 masks
C 10.0.4.0/22 is directly connected, GigabitEthernet2
C 10.0.6.0/24 is directly connected, GigabitEthernet2
L 10.0.6.1/32 is directly connected, GigabitEthernet2
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.16.27.0/30 is directly connected, GigabitEthernet3
L 172.16.27.1/32 is directly connected, GigabitEthernet3
Routing Table:

S 10.0.0.0/22 [1/0] via GigabitEthernet1
S 10.0.4.0/22 [1/0] via GigabitEthernet2
172.16.0.0/16 is variably subnetted, 2 subnets, 2 masks
C 172.16.27.0/30 is directly connected, GigabitEthernet2
L 172.16.27.2/32 is directly connected, GigabitEthernet2
C 172.16.27.4/30 is directly connected, GigabitEthernet1

Install Static Route to 10.0.0.0/22 via 172.16.27.1 (assuming Router C ' s IP is 172.16.27.1):
Destination Prefix: 10.0.0.0
Destination Prefix Mask: 255.255.252.0
Interface: GigabitEthernet3
Install Static Route to 10.0.4.0/22 via 172.16.27.5 (assuming Router C ' s IP is 172.16.27.5):
Destination Prefix: 10.0.4.0
Destination Prefix Mask: 255.255.252.0
Interface: GigabitEthernet1
Install Static Route to 10.0.6.0/24 via 172.16.27.2 (assuming Router A ' s IP is 172.16.27.2):
Destination Prefix: 10.0.6.0
Destination Prefix Mask: 255.255.255.0
Interface: GigabitEthernet2
Install Static Route to 10.0.0.0/22 via 172.16.27.1 (assuming Router B ' s IP is 172.16.27.1):
Destination Prefix: 10.0.0.0
Destination Prefix Mask: 255.255.252.0
Interface: GigabitEthernet1
Summary of Static Routes:
Router A:
ip route 10.0.0.0 255.255.252.0 GigabitEthernet3
Router B:
ip route 10.0.4.0 255.255.252.0 GigabitEthernet1
Router C:
ip route 10.0.6.0 255.255.255.0 GigabitEthernet2
ip route 10.0.0.0 255.255.252.0 GigabitEthernet1
These configurations ensure that each router knows the correct paths to reach Workstation A and File Server
2, resolving the connectivity issue.
