For an interface to be configured in dual-port mode, I must first configurethe interface as a _______member of each VLAN.a. taggedb. untaggedc. nond. dual-port3. What is the largest VLAN ID I can configure?a. 1024b. 65535c. 4095d. 163834. An untagged interface may be a member of how many different VLANs?a. 1b. 2c. 8d. 165. If I wanted to create VLAN 50 on my switch, which command would I use?a. ip vlan 50b. show vlan 50c. vlan 50d. interface ve 506. If I needed to configure hundreds of VLANs on the same switch, and eachof the VLANs needed to be configured identically, what could I use?a. VLAN Groupb. IEEE 802.1qc. IEEE 802.1pd. Layer 3 VLANBrocade <strong>IP</strong> Primer 189
Chapter 8: Virtual Local Area Network (VLAN)7. When configuring a Layer 3 VLAN, which command defines the virtualinterface for the VLAN?a. vlan 50b. interface ve 50c. router-interface ve 50d. tagged ve 508. What command would I use to make e 6 an IEEE 802.1q-tagged memberof a VLAN?a. ieee 802.1q interface e 6b. q e 6c. interface e 6 802-1qd. tagged e 69. What command would I use to make the first 16 interfaces of my switchuntagged members of a VLAN?a. ieee 802.1q interface e 1-16b. untagged e 1 to 16c. untagged e 1-16d. interface e 1 to 16 802-1q10. What would happen if you connected an untagged interface on oneswitch to an 802.1q-tagged interface on another switch?a. Communication would fail, the tagged switch would be expectinglarger framesb. The tagged switch port would negotiate to dual-port modec. The tagged switch would superimpose the 802.1q headeraccordinglyd. The untagged switch port would negotiate to dual-port modeAnswers to Review Questions1. b. 4 bytes. The TPID (which identifies the frame as tagged) takes up 16bits (2 bytes). The Priority field takes up 3 bits. The CFI takes up one bit.And the VLAN ID field takes up 12 bits. 16 + 3 + 1 + 12 = 32 bits; 32 ÷ 8= 4 bytes.2. a. The interface must start as a tagged member of all VLANs. Then, in theInterface config, it will specify the VLAN to which it is to be an untaggedmember.3. c. The VLAN ID is a 12-bit field. With 12 bits, the largest number you canrepresent is 4,095.190 Brocade <strong>IP</strong> Primer
