Question 1

On the DiffServ network, what is the main purpose of defining the service type of the EF classification?

APreferentially guarantee the services that require short delay, low packet loss, low jitter, and assured bandwidth.

BProvide channels for packet forwarding.

CEnsure bandwidth for specific traffic.

DEnsure that packets are forwarded with the minimum delay.

Answer : B

Question 2

Which of the following statements regarding the access control application scenario of the Agile Controller is false?

AIn MAC address authentication, user terminals are authenticated by the authentication server based on their MAC addresses. MAC address authentication is mainly used to authenticate dumb terminals, such as IP phones and printers.

B802.IX authentication uses the Extensible Authentication Protocol (EAP) to transmit authentication information between the client, access device, and authentication server.

CPortal authentication is also called web authentication. Users enter their account information on the web authentication page for identity authentication.

DIn SACG authentication, the USG firewall is connected to a router or switch in bypass mode, and terminal access is controlled by manual monitoring.

Answer : A

Question 3

Which of the following is not the application scenario of the guest access management function of the Agile Controller?

ACustomers access the enterprise network, public resources, or Internet during exchanges with or visits to the enterprise.

BCitizens access the Internet through the network provided by public utilities.

CConsumers connect to the Internet over the enterprise network.

DEnterprise employees on a business trip connect to the enterprise network through the branch network.

Answer : D

Question 4

A DHCP client needs to obtain an IP address from the DHCP server when accessing a network for

the first time. When the client accesses the network again, which of the following statements are true?

(Multiple Choice)

AThe DHCP client broadcasts a DHCP Discover packet. The DHCP server replies to the packet.

BThe DHCP client only needs to broadcast a DHCP Request packet containing the IP address obtained last time, but does not need to send a DHCP Discover packet again.

CAfter receiving the DHCP Discover packet, the DHCP server sends a DHCP Offer packet containing the leased IP address and other settings to the DHCP client.

DAfter receiving the DHCP Request packet, the DHCP server returns a DHCP ACK packet if the requested IP address is not allocated to another client.

Answer : B, D

Question 5

Which of the following statements regarding the delay and jitter are true? (Multiple Choice)

AThe E2E delay is the sum of processing delays and queue delays.

BThe jitter occurs because the E2E delays of each packet are different.

CThe jitter is relevant to the delay, A small delay indicates a small jitter, A large delay indicates a large jitter.

Answer : B, C

Question 6

To provide differentiated services for different users, users or services are classified based on packet information such as the packet priority, source IP address, and port number. Which QoS technologies are often used to implement classification?

ATraffic policing

BComplex traffic classification

CCongestion avoidance

DCongestion management

Answer : B

Question 7
