NEW QUESTION # 78
Which of the following statements regarding static routing and dynamic routing is incorrect?
Answer: A
Explanation:
Static routing does not automatically recover from link failures; manual reconfiguration is required if a static route path becomes invalid. Dynamic routing protocols, on the other hand, adapt automatically to network changes, adjusting routes as needed.
NEW QUESTION # 79
R1 has the following configurations:
[R1] nat server for_telnet protocol tcp global 100.0.23.2 telnet inside 192.168.1.1 telnet When a public network user and 100.0.23.2 are reachable, the public network user can run the telnet
192.168.1.1 command to log in to 192.168.1.1.
Answer: B
Explanation:
The nat server configuration creates a static mapping so that an internal Telnet server at private address
192.168.1.1 can be reached from the public network using global address 100.0.23.2 on the Telnet TCP port.
The purpose of NAT Server is to expose an internal service through a reachable public address and translate incoming packets to the inside host. A public user therefore initiates the connection to the configured global address, for example telnet 100.0.23.2, assuming routing and security policies allow the session. The user does not normally issue telnet 192.168.1.1 from the public network because that is the private inside address and is not the destination on which the public-side NAT mapping is matched. After the packet reaches R1 addressed to 100.0.23.2, R1 translates the destination to 192.168.1.1 and forwards it internally. Thus the configuration can make the private server reachable, but the command stated in the question uses the wrong destination address. The statement is FALSE, option B.
NEW QUESTION # 80
Drag and Drop Question
When requesting an IPv4 address for the first time, a DHCPv4 client needs to exchange four messages with the DHCPv4 server. Drag and drop the DHCPv4 packets to the correct positions based on the packet interaction sequence.
Answer:
Explanation:
Explanation:
1 - DHCP DISCOVER
2 - DHCP OFFER
3 - DHCP REQUEST
4 - DHCP ACK
A DHCP client first broadcasts a Discover message to locate a DHCP server. The server responds with an Offer containing an available IP address. The client then sends a Request to confirm the selected address, and finally the server replies with an ACK to complete the allocation process.
NEW QUESTION # 81
Unlike distance-vector routing protocols, link-state routing protocols advertise link states instead of route information. Typical link-state routing protocols include RIP, OSPF, and IS-IS.
Answer: B
Explanation:
Link-state routing protocols advertise link-state information rather than full routing tables or route updates. However, RIP is not a link-state protocol; it is a distance-vector protocol. Only OSPF and IS-IS are link-state protocols, so the statement is incorrect.
NEW QUESTION # 82
On the network shown in the figure, R1 serves as the gateway for PC2 and PC3, and directly connects to S1 through a physical link. GE1/0/1 on S1 is configured as a trunk interface and permits traffic of VLANs 2 and 3. Its PVID retains the default value. Which of the following statements are true if PC2 and PC3 can communicate with each other? (Select all that apply)
Answer: A,B,C
Explanation:
This scenario describes the classic router-on-a-stick inter-VLAN routing design. A single physical interface on R1 connects to switch S1, and multiple sub-interfaces are created on that physical interface to serve as gateways for multiple VLANs. Therefore, if R1 provides Layer 3 gateway functions for VLAN 2 and VLAN 3, sub-interfaces such as GE0/0/1.2 and GE0/0/1.3 must be configured, so option A is correct.
Because PC2 and PC3 are connected to switch S1, S1 learns their source MAC addresses dynamically and stores them in its MAC address table, making option B correct. R1 receives tagged frames from different VLANs on the trunk link and, through its sub-interfaces, can identify and terminate frames for VLAN 2 and VLAN 3, so option C is also correct.
