질문 # 158
Which statement is true about Layer 2 firewall filters on EX Series switches?

A. They are stateless and evaluated by the control plane.
B. They are stateful and evaluated by the control plane.
C. They are stateful and evaluated by the forwarding plane.
D. They are stateless and evaluated by the forwarding plane.

정답：D

질문 # 159
Both the R1 and R2 devices are advertising prefix X into AS 65530 with the BGP attributes shown in the exhibit.

Which statement is correct in this scenario?

A. R2's version of prefix X will be active because of the AS path attribute.
B. R1's version of prefix X will be active because of the AS path attribute.
C. R1's version of prefix X will be active because of the local preference attribute.
D. R2's version of prefix X will be active because of the local preference attribute.

정답：A

질문 # 160
Referring to the exhibit, which statement is correct?

A. The local device is using a bridge priority of 4k.
B. The root bridge has not been elected for this RSTP topology.
C. The local device is the root bridge for this RSTP topology.
D. The root bridge is using a bridge priority of 4k.

정답：D

설명：
The "Root ID" shows 4096.00:19:e2:55:36:1e. The first part of this ID, 4096, is the bridge priority of the root bridge.
The local bridge ID is shown as 32768.00:19:e2:55:1d:30, indicating that the local device has a default bridge priority of 32768, which is higher (and thus less preferred) than 4096.
Thus, the root bridge has a priority of 4096, and the local device is not the root bridge. The local device is participating in the RSTP topology and has identified another bridge as the root.

질문 # 161
A number of reports from end users indicate that internal and external communications are intermittent and not reliable. You verified the status of the switch ports and have determined that they are up and operational. You also noticed a very high level of link bandwidth utilization on those same ports. The current topology of the affected environment is shown in the exhibit.

What would be the cause of the reported issues?

A. A misconfigured interior gateway protocol (IGP).
B. A malformed route-based ACL improperly filtering traffic flows.
C. A lack of port-based ACLs filtering the traffic flows.
D. A lack of a loop-prevention mechanism or protocol.

정답：D

질문 # 162
You are concerned about spoofed MAC addresses on your LAN. Which two Layer 2 security features should you enable to minimize this concern? (Choose two.)

A. DHCP snooping
B. static ARP
C. IP source guard
D. dynamic ARP inspection

정답：A,D

설명：
A is correct because dynamic ARP inspection (DAI) is a Layer 2 security feature that prevents ARP spoofing attacks. ARP spoofing is a technique that allows an attacker to send fake ARP messages to associate a spoofed MAC address with a legitimate IP address. This can result in traffic redirection, man-in-the-middle attacks, or denial-of-service attacks. DAI validates ARP packets by checking the source MAC address and IP address against a trusted database, which is usually built by DHCP snooping. DAI discards any ARP packets that do not match the database or have invalid formats. C is correct because DHCP snooping is a Layer 2 security feature that prevents DHCP spoofing attacks. DHCP spoofing is a technique that allows an attacker to act as a rogue DHCP server and offer fake IP addresses and other network parameters to unsuspecting clients. This can result in traffic redirection, man-in-the-middle attacks, or denial-of-service attacks. DHCP snooping filters DHCP messages by classifying switch ports as trusted or untrusted. Trusted ports are allowed to send and receive any DHCP messages, while untrusted ports are allowed to send only DHCP requests and receive only valid DHCP replies from trusted ports. DHCP snooping also builds a database of MAC addresses, IP addresses, lease times, and binding types for each client.
