질문 # 55
Which of the following number sequences can be matched by the regular expression 100.s?

A. 0
B. 1
C. 2
D. 3

정답：A

설명：
Comprehensive and Detailed
The regular expression 100.s follows these rules:
100 matches exactly the sequence 100.
. (dot) represents any single character (digit, letter, or symbol).
s specifically looks for the character s, but it is not included in the given choices.
Now, analyzing each option:
✔ 1000 matches → 1000 (fourth character matches . as a wildcard).
✘ 100 does not match → No extra character after 100.
✘ 10000 does not match → Too many extra characters.
✘ 1001 does not match → s is not present.
Thus, 1000 is the correct answer (C).

질문 # 56
In a scenario where a VXLAN tunnel is dynamically established through BGP EVPN, which of the following fields is not carried in BGP EVPN Type 2 routes?

A. L2VNI
B. L3VNI
C. IP Prefix
D. IP Address

정답：C

설명：
BGP EVPN Route Types in VXLAN:
BGP EVPN Type 2 Route (MAC/IP Advertisement Route)
Used forhost reachability advertisement.
Carries MAC and IP address information of endpoints.
Does not carry an IP Prefix field(Type 5 routes handle prefixes).
Correct Explanation of Answer Choices:#IP Address (B) is included- Used for host mobility and reachability.
#L3VNI (C) is included- Used forLayer 3 VXLAN routing.#L2VNI (D) is included- Used forLayer 2 VXLAN bridging.#IP Prefix (A) is not included in Type 2 routes- It is part ofEVPN Type 5 routesforprefix advertisement.

B. MP-BGP can be used to assign tags.
C. The MP_UNREACH_NLRl of the update message, excluding the path nationality.
D. A complete MP_REACH_NLRI attribute structure contains address family, next hop, and prefix information.

정답：A

질문 # 58
To allow only authorized users (users who obtain IP addresses through authorized DHCP servers or use specified static IP addresses) to access the network shown in the figure, which of the following solutions can be used?

A. DAI + Port Security
B. DHCP Snooping + DAI
C. DHCP Snooping + IPSG
D. DAI + IPSG

정답：C

설명：
Understanding Network Security for Authorized User Access
# Problem Scenario:
* Only authorized users should be allowed network access.
* Users can obtain IP addresses either via DHCP or a predefined static IP list.
* Unauthorized users (e.g., attackers using rogue DHCP servers or spoofed IPs) must be blocked.
# Required Technologies for Securing Access:1## DHCP Snooping - Protects against rogue DHCP servers and builds a binding table of legitimate DHCP clients.2## IP Source Guard (IPSG) - Ensures that only authorized IP-MAC bindings can send traffic.
Analysis of the Answer Choices:
# A. DAI + Port Security (Incorrect)
* DAI (Dynamic ARP Inspection) prevents ARP spoofing but does not validate IP-MAC-DHCP bindings.
* Port Security only limits MAC addresses per port but does not verify IP addresses.
* Does NOT protect against unauthorized static IP users.
# B. DHCP Snooping + IPSG (Correct)
* DHCP Snooping:
* Prevents rogue DHCP servers from assigning unauthorized IPs.
* Builds a DHCP binding table (IP-MAC-Port).
* IP Source Guard (IPSG):
* Blocks traffic from IPs not listed in the DHCP snooping binding table.
* Can be configured to allow manually specified static IP addresses.
* Best choice to allow only authorized users (both DHCP and static IP users).
# C. DHCP Snooping + DAI (Incorrect)
* DAI (Dynamic ARP Inspection) prevents ARP spoofing but does not block unauthorized static IP users.
* Lacks IP-level access control needed to enforce static IP policies.
# D. DAI + IPSG (Incorrect)
* IPSG (IP Source Guard) needs DHCP Snooping to build the binding table.
* Without DHCP Snooping, IPSG cannot function properly.
* DAI does not provide complete protection against unauthorized users.
Why is the Answer B (DHCP Snooping + IPSG)?
# Ensures only users assigned a DHCP IP (or authorized static IPs) can send traffic.# Blocks rogue DHCP servers and unauthorized static IP users.
Real-World Application:
* Enterprise Networks: Prevents unauthorized static IP users or attackers from accessing VLANs.
* Public Wi-Fi Security: Ensures only authorized users receive IPs and can send traffic.

질문 # 59
Refer to the following command output on the router R1. Which of the following statements isincorrect?
< R1 > display interface Tunnel
Tunnel0/0/0 current state : UP
Line protocol current state : UP
Last line protocol up time : 15:21:23 UTC-08:00
Description: ! 0.0.3.3
Route Port, The Maximum Transmit Unit is 1500
Internet Address is 20.1.1.1/24
Encapsulation is TUNNEL, loopback not set
Tunnel source 10.0.1.1 (LoopBack0), destination 10.0.3.3
Tunnel protocol/transport GRE/IP, key disabled
keepalive disabled
Checksumming of packets disabled
Current system time: 15:21:37-08:00
300 seconds input rate 0 bits/sec, 0 packets/sec
300 seconds output rate 0 bits/sec, 0 packets/sec
13 seconds input rate 0 bits/sec, 0 packets/sec
13 seconds output rate 448 bits/sec, 0 packets/sec
9 packets output, 824 bytes
0 output error
Input bandwidth utilization : -
Output bandwidth utilization : -

A. Key authentication is disabled for the tunnel.
B. Keepalive detection is enabled on the tunnel.
C. The destination IP address of the tunnel is 10.0.3.3.
D. The tunnel is a GRE tunnel.

정답：B

설명：
Comprehensive and Detailed In-Depth Explanation:
Analyzing the output:
A). Key authentication is disabled for the tunnel:Correct. The output explicitly states " key disabled " .
B). The destination IP address of the tunnel is 10.0.3.3:Correct. The output shows " destination 10.0.3.3 " .
C). The tunnel is a GRE tunnel:Correct. The output states " Tunnel protocol/transport GRE/IP " .
D). Keepalive detection is enabled on the tunnel:Incorrect.The output clearly shows " keepalive disabled " .
Therefore, the correct answer isDbecause the tunnel doesnot have keepalive enabled.
