Question 183

Which of the following values is the Reserved/Circuit Type field in the IIH packets sent by a Level-1-2 router on an IS-IS network?

A.00
B.11
C.01
D.10

Correct Answer: B

Comprehensive and Detailed In-Depth Explanation:
* Intermediate System to Intermediate System (IS-IS) routers send IS-to-IS Hello (IIH) packets to establish neighbor relationships.
* The Reserved/Circuit Type field in IIH packets indicates which level of IS-IS adjacency the router is trying to establish:
* 00 # Level-0 (Not used in IS-IS).
* 01 # Level-1 router.
* 10 # Level-2 router.
* 11 # Level-1-2 router (Both levels supported).
* Since the question asks for the field value in an L1-L2 router's IIH packets, the correct answer is 11 (B).
# Reference: Huawei HCIA-Datacom Study Guide, IS-IS Neighbor Discovery and IIH Packet Format.

Question 184

A session is an entry used to record the connection status of a protocol and is fundamental for the firewall to forward packets. Which of the following protocol packets will the firewall create sessions for?

A.Subsequent fragment
B.ICMP error packet
C.GRE
D.TCP

Correct Answer: C,D

Comprehensive and Detailed Step-by-Step Explanation:
1. What is a Firewall Session?
* A firewall session is an entry used to maintain the connection state of a protocol.
* When a packet is forwarded, the firewall creates a session for it and tracks subsequent packets for the same connection to ensure efficient forwarding and security enforcement.
2. Analysis of Each Option:
Option A: Subsequent fragment
* Incorrect.
* A session is created for the initial fragment of a packet. Subsequent fragments are matched to the existing session and do not trigger the creation of a new session.
Option B: ICMP error packet
* Incorrect.
* ICMP error packets (e.g., Destination Unreachable) are considered exceptions and do not create new sessions.
Option C: GRE (Generic Routing Encapsulation)
* Correct.
* GRE is a tunneling protocol that encapsulates packets. A firewall creates a session for GRE traffic to track the state of the encapsulated connection.
Option D: TCP (Transmission Control Protocol)
* Correct.
* TCP is a connection-oriented protocol, and firewalls create sessions for TCP connections to track their state (e.g., SYN, SYN-ACK, FIN).
3. Summary:
* The firewall creates sessions for GRE and TCP protocols.
