    Which encapsulation types are configurable on a Cisco switch for a trunk? (Select two answer choices)

    A. VTP

    B. ISL

    C. CDP

    D. 802.1Q

    E. 802.1p

    F. LLC

    G. IETF


    正确答案：BD
    B,D 解析：Explanation:
    Trunks are used to carry traffic belonging to multiple VLANs between devices over the same link. A device can determine which VLAN the traffic belongs to by its VLAN identifier. The VLAN identifier is a tag that is encapsulated with the data. ISL and 802.1q are two types of encapsulations used to carry data from multiple VLANs over trunk links.

    ISL is a Cisco proprietary protocol for interconnecting multiple switches and maintaining VLAN information as traffic goes between switches. ISL provides VLAN trunking capabilities while maintaining full wire speed performance on Ethernet links in full-duplex or half-duplex mode. ISL operates in a point-to-point environment and will support up to 1000 VLANs.

    In ISL, the original frame. is encapsulated and an additional header is added before the frame. is carried over a trunk link. At the receiving end, the header is removed and the frame. is forwarded to the assigned VLAN. .ISL uses Per VLAN Spanning Tree (PVST) which runs one instance of Spanning Tree Protocol (STP) per VLAN.

    PVST allows for optimal root switch placement for each VLAN and supports load balancing of VLANs over multiple trunk links. 802.1Q is the IEEE standard for tagging frames on a trunk and supports up to 4096 VLANs. In 802.1Q, the trunking device inserts a four-byte tag into the original frame. and re-computes the Frame. Check Sequence (FCS) before sending the frame. over the trunk link. At the receiving end, the tag is removed and the frame. is forwarded to the assigned VLAN. 802.1Q does not tag frames on the native VLAN.

    It tags all other frames transmitted and received on the trunk. While configuring a 802.1 trunk, you must make sure that the same native VLAN is configured on both sides of the trunk. IEEE 802.1Q defines a single instance of spanning tree running on the native VLAN for all the VLANs in the network which is called Mono Spanning Tree (MST). This lacks the flexibility and load balancing capability of PVST available with ISL. However, PVST+ offers the capability to retain multiple Spanning Tree topologies with 802.1Q trunking.

  • 第2题：

    Which two of the following values does STP take into consideration when it elects the root bridge? (Select two answer choices)

    A. The BPDU version number

    B. The access layer bridge setting

    C. The Bridge ID

    D. The spanning-tree update number

    E. The bridge priority

    F. The VLAN number


    正确答案：CE
    C,E 解析：Explanation:
    The bridges elect a root bridge based on the bridge IDs in the BPDUs. The root bridge is the bridge with the lowest numeric value for the bridge ID. Because the two part bridge ID starts with the priority value, essentially the bridge with the lowest priority becomes the root.

    For instance, if one bridge has priority 100, and another bridge has priority 200, the bridge with priority 100 wins, regardless of what MAC address was used to create the bridge ID or each bridge/switch.

    You need to configure two Ezonexam switches to exchange VLAN information. Which protocol provides a method of sharing VLAN configuration information between these two switches?

    A. STP

    B. 802.1Q

    C. VLSM

    D. ISL

    E. VTP

    F. HSRP

    G. None of the above


    正确答案：E
    E 解析：Explanation:
    VLAN Trunking Protocol (VTP) is a Cisco proprietary Layer 2 messaging protocol that manages the addition, deletion, and renaming of VLANs on a network-wide basis. Virtual Local Area Network (VLAN) Trunk Protocol (VTP) reduces administration in a switched network.

    When you configure a new VLAN on one VTP server, the VLAN is distributed through all switches in the domain. This reduces the need to configure the same VLAN everywhere. To do this VTP carries VLAN information to all the switches in a VTP domain. VTP advertisements can be sent over ISL, 802.1q, IEEE 802.10 and LANE trunks.

    VTP traffic is sent over the management VLAN (VLAN1), so all VLAN trunks must be configured to pass VLAN1. VTP is available on most of the Cisco Catalyst Family products.
