質問 # 237
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?
正解：A、C
解説：
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 forGREandTCPprotocols.

質問 # 238
Which of the following descriptions about OSPF Router ID is correct?
正解：B
質問 # 239
BGP is a distance-vector protocol that implements route reachability between ASs and selects optimal routes.
Which of the following statements are true about this protocol?
正解：B、D
解説：
Comprehensive and Detailed Step-by-Step Explanation:
1. Overview of BGP:
BGP (Border Gateway Protocol) is an Exterior Gateway Protocol (EGP) designed to exchange routing information between different Autonomous Systems (ASs) on the internet. Unlike traditional distance-vector protocols (like RIP), BGP is considered a path-vector protocol, as it not only determines reachability but also ensures policy-based routing decisions and advanced path selection mechanisms.
2. Analysis of Each Option:
Option A: BGP does not support authentication. Therefore, it cannot ensure network security.
This statement isincorrect.
BGP supports authentication using mechanisms such as TCP MD5 (Message Digest 5) and TCP-AO (Authentication Option). These authentication mechanisms ensure that BGP messages are not tampered with or intercepted during transmission, enhancing network security.
HCIA-Datacom Study Guide, Chapter "BGP Concepts and Features," Authentication Section.
Option B: BGP uses TCP as the transport layer protocol.
This statement iscorrect.
BGP relies on TCP (Transmission Control Protocol) as its transport layer protocol, specifically on port 179.
TCP provides reliable delivery of BGP messages and ensures the session remains established in case of transient network issues.
TCP also handles error recovery and sequencing, making it a suitable choice for BGP, which requires reliable communication between peers.
Reference: HCIA-Datacom Study Guide, Chapter "BGP Basics," Transport Protocol Section.
Option C: BGP provides various routing policies.
This statement iscorrect.
One of the primary advantages of BGP is its robust routing policy configuration capabilities. Administrators can define import and export policies, route preferences, and community attributes to influence routing decisions. This allows for granular control over which routes are advertised or accepted.
Routing policies make BGP a highly flexible protocol for large-scale and complex networks.
Reference: HCIA-Datacom Study Guide, Chapter "BGP Route Policies," and "Attributes Overview." Option D: BGP supports automatic peer discovery.
This statement isincorrect.
BGP does not support automatic peer discovery. All BGP peers must be manually configured with their IP addresses and AS numbers. This ensures precise control over peer relationships, but also increases administrative overhead.
In contrast, some IGPs (Interior Gateway Protocols) like OSPF support automatic neighbor discovery.
Reference: HCIA-Datacom Study Guide, Chapter "BGP Neighbor Relationships," Manual Configuration Section.
Summary of Correct Answers:
Correct Options:B, C
Incorrect Options:A, D

質問 # 240
Which of the following mechanisms or techniques can VRRP be combined with to monitor uplink connectivity? (Multiple choice)
正解：A、B、C、D
質問 # 241
Which of the following statements regarding OSPF route summarization is false?
正解：A
解説：
Route summarization in OSPF is restricted to specific routers: Area Border Routers (ABRs) and Autonomous System Boundary Routers (ASBRs). These devices perform summarization to reduce routing table size and minimize advertised routing information between areas or across AS boundaries. Regular routers cannot perform route summarization, making this statement false .
