Question 1

Traffic policing usually uses which of the following QoS technologies?

Accepted Answer

CAR (Committed Access Rate) is a QoS technology used for traffic policing to control the rate of traffic flow in a network.

Question 2

Which of the following NAT functions are supported by the Eudemon? (Choose three.)

Accepted Answer

The answer of Which of the following NAT functions are...

Question 3

When a client applies for an IP address through DHCP, which message is the unicast message?

Accepted Answer

All the initial DHCP messages (DISCOVER, OFFER, REQUEST) are broadcast messages. Unicast messages are typically used after the IP address has been assigned and acknowledged.

Question 4

Which of the following statements are correct regarding MAC address of VRRP packet? (Choose two.)

Accepted Answer

The answer of Which of the following statements are correct...

Question 5

Which of the following numbers is the protocol number of VRRP packets?

Accepted Answer

The protocol number for VRRP (Virtual Router Redundancy Protocol) packets is 112.

Question 6

If the Open message sent from a BGP speaker has the GR capability field but no <AFI, SAFI> field, the BGP speaker has no backup forwarding table. Such a BGP speaker functions as only the GR helper to help its neighbors complete the GR process.

Accepted Answer

The absence of the <AFI, SAFI> field in the GR capability indicates that the BGP speaker does not support any specific address families for GR, implying it cannot maintain a backup forwarding table and can only act as a GR helper.

Question 7

If you have run the dot1x port-method command with the port parameter specified (port-based 802.1x authentication), the maximum number of users on an interface changes to 1. In this case, which statements are true? (Choose two.)

Accepted Answer

The answer of If you have run the dot1x port-method...

Question 8

What is the legal virtual MAC address in VRRP?

Accepted Answer

The legal virtual MAC address for VRRP (Virtual Router Redundancy Protocol) is 00-00-5E-00-01-XX, where XX is the VRRP group ID.

Question 9

Which of the following statements about the VRRP working process is false?

Accepted Answer

In VRRP, a backup router does not immediately become the master router if its priority is higher than the current master router. The master router remains the master until it fails or is manually reconfigured.

Question 10

Which of the following statement about QoS in DiffServ mode is false?

Accepted Answer

DiffServ does not require applications to confirm resource reservation before sending packets, as it operates on a per-hop behavior basis without end-to-end resource reservation.

Question 11

Which of the following statement about packet marking is false?

Accepted Answer

The IP address of a packet is not typically marked for Quality of Service (QoS) purposes. Packet marking usually involves fields like DSCP, IP precedence, or 802.1p for prioritizing traffic, not the IP address itself.

Question 12

Simple traffic classification can be performed based on which of the following information in IPv4 packets? (Choose two.)

Accepted Answer

DSCP (Differentiated Services Code Point) and IP precedence are both used for simple traffic classification in IPv4 packets.

Question 13

The Per-Hop Behavior (PHB) defines the policy and priority applied to a packet when traversing a hop (such as a DS) in a DiffServ network.

Accepted Answer

The Per-Hop Behavior (PHB) in a Differentiated Services (DiffServ) network specifies the treatment packets receive at each network node, determining their forwarding priority and resource allocation.

Question 14

When the GR Restarter performs the active/standby switchover, the neighbor performs which of the following operations when detecting that a TCP disconnection? (Choose three.)

Accepted Answer

The answer of When the GR Restarter performs the active/standby...

Question 15

Which of the following information in a packet can be marked or re-marked?

Accepted Answer

IP DSCP, IP precedence, and 802.1p information are fields that can be marked or re-marked for Quality of Service (QoS) purposes, unlike IP source/destination addresses or MAC addresses which are not typically altered.

Question 16

What is the sequence of applying for an IP address in DHCP? 1. The host sends a DHCP Request message to apply for an IP address. 2. The DHCP server replies with a DHCP Offer message. 3. The host sends a DHCP Discovery message to search for the DHCP server. 4. The DHCP server replies with a DHCP ACK message after receiving the DHCP Request message.

Accepted Answer

The correct sequence is: 3. DHCP Discovery, 2. DHCP Offer, 1. DHCP Request, 4. DHCP ACK.

Question 17

When the DHCP relay receives a DHCP request message in which the giaddr (gateway IP address) field is 0, how does the DHCP relay process the DHCP request message?

Accepted Answer

The DHCP relay agent fills its own IP address in the giaddr field to indicate the network segment from which the request originated and then forwards the request to the DHCP server using unicast.

Question 18

OSPF directly runs over the IP protocol. Its IP protocol number is 89.

Accepted Answer

OSPF (Open Shortest Path First) is a routing protocol that operates directly over the IP layer and uses IP protocol number 89 for its communication.

Question 19

The Eudemon supports load balancing between multiple uplinks.

Accepted Answer

The Eudemon supports load balancing between multiple uplinks, allowing for increased bandwidth and redundancy.

Question 20

The Eudemon does not support port mapping.

Accepted Answer

The Eudemon, a type of firewall, does support port mapping, which is a common feature in network devices to allow specific traffic through the firewall.
