NEW QUESTION # 44
BGP can select routes based on the AS_Path attribute. Therefore, in some cases, a route-policy needs to be used to modify the AS_Path attribute for route selection. Which of the following parameters can be specified in the apply as-path command for a route-policy to modify this attribute?

  • A. Copy
  • B. Additive
  • C. Overwrite
  • D. Delete

Answer: B,C,D

Explanation:
Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of AS_Path Attribute Modification:
The apply as-path command in a route-policy is used to modify the AS_Path attribute of routes. This is often required to influence the selection of routes or to adjust routing policies for incoming or outgoing BGP updates.
2. Parameters of the apply as-path Command:
Option A: Delete
* Correct.
* The delete parameter removes specific AS numbers from the AS_Path attribute. This is used to simplify or manipulate the AS_Path for specific routing policies.
Option B: Additive
* Correct.
* The additive parameter appends an AS number to the existing AS_Path attribute, instead of overwriting it. This is useful when you want to prepend AS numbers to influence route selection without removing the original AS_Path.
Option C: Copy
* Incorrect.
* The copy parameter is not supported in the apply as-path command for modifying AS_Path attributes.
Option D: Overwrite
* Correct.
* The overwrite parameter replaces the existing AS_Path with a new one. This provides complete control over the AS_Path attribute but removes the original AS_Path entirely.
3. Summary:
The valid parameters for the apply as-path command are delete, additive, and overwrite.

What parameters can a DHCP6 server assign to a DHCPv6 client?

  • A. SNTP server address
  • B. Gateway address
  • C. DNS server address
  • D. IPV6 address/prefix

Answer: A,C,D

* It supports both stateful and stateless modes:
* Stateful: Assigns IPv6 addresses and other configuration parameters.
* Stateless: Assigns only configuration parameters (e.g., DNS server) without providing IPv6 addresses.


NEW QUESTION # 47
As shown in the figure, the stateful inspection firewall forwards the packet because the packet matches the session status of the firewall.

  • A. TRUE
  • B. FALSE

Answer: A

Explanation:
A stateful inspection firewall tracks the state of active connections. If a packet matches an existing session in the firewall's state table, it is allowed to pass. The diagram indicates that the TCP packet matches the session state, so the firewall forwards it .
