With reference to the previous figure, judge the following item.
Two layer 2 switches were connected through redundant connections, with a view to improving network availability. Considering this hypothetical situation, judge the following item.
Unlike layer 3 switches, which allow network management through TTL (time-to-live), layer 2 switches, such as the one described in the presented architecture, do not prevent loops in the network, something that can be prevented by the STP protocol (spanning tree protocol) with the implementation of the algorithm defined in IEEE 802.1.d. true false. Two layer 2 switches were connected via redundant connections in order to improve network availability. Considering this hypothetical situation, consider the following item. If these two switches were inserted into a VLAN, the recommendation for improving security would be to use the technique known as hardening, which consists of creating a subnet (layer-3) associated with the respective VLAN (layer-2), so that host access to servers would have to go through the security policies imposed by routers with firewall functions. true false. It is possible to measure the performance of the Primary and Secondary servers, as well as the Network Switch, through SNMP (Simple Network Management Protocol), which is an application layer protocol, not connection-oriented and that uses the UDP protocol to exchange information between network devices. true false. Regarding Figure 01, select the correct alternative: I. HostA can communicate with HostB, but not with HostC and HostD. II. Communication between all hosts is possible, since they are connected to the same equipment, which is a network router. III. VLAN 100 and VLAN 200 create a single broadcast domain on the network, containing HostA, HostB, HostC and HostD. IV. VLANs are a type of physical network created with the objective of segmenting several subnets within a single Switch. The following statements are correct: A-I, II, III and IV. B- I and III, only. C- I, only. D- II, III and IV, only. E= II and IV, only. Figure 1 - Network diagram Regarding Figure 01, select the correct alternative: I. There are 04 distinct networks connected to the Switch; computers on each network can communicate with each other, but not with computers on different networks. II. Communication between all hosts on the 04 networks is perfectly possible, since they are connected to the same Switch. III. Computers connected to Network 01 can communicate with computers on Network 02, Network 03, and Network 04, since the Switch routes the packets. IV. The switch is a network device that operates at layer 01 of the OSI model. This means that it transmits data through the existing physical infrastructure, sending the received messages to all other devices on the networks. The following statements are correct: A- I, II, and III. B= II, only. C= I, only. D= III, only. |
