Question No: 4
Which two statements about the monitored traffic in a SPAN session are true? (Choose two)
A. You cannot configure two separate SPAN or RSPAN source sessions with separate or overlapping sets of SPAN source ports and VLANs.
B. By default, all monitored packets are captured without the IEEE 802.1Q tag
C. Egress SPAN monitors packets sent by the source interface before any QoS modifications
D. Sources can be ports or VLANs or any combination in the same session
E. By default, all monitored packets include the IEEE 802.1Q tag that they had on the source port
F. Ingress SPAN monitors packets received by the source interface before any QoS modifications
Answer: C,D
Question No: 5
Which HSRP extension allows groups to share traffic loads?
A. GLBP
B. CHSRP
C. MHSRP
D. CGMP
E. FHRP
Answer: C
Question No: 6
Which two statements about the HSRP priority are true? (Choose two)
A. To assign the HSRP router priority in a standby group, the standby group-number priority priority-value global configuration command must be used.
B. The default priority of a router is zero (0).
C. The no standby priority command assigns a priority of 100 to the router.
D. Assuming that preempting has also been configured, the router with the lowest priority in an HSRP group would become the active router.
E. When two routers in an HSRP standby group are configured with identical priorities, the router with the highest configured IP address will become the active router.
Answer: C,E
Question No: 7
Which two statements about HSRP, GLBP, and VRRP are true? (Choose two.)
A. HSRP is the preferred protocol to be used on multivendor environments.
B. VRRP has one master router, one standby router, and many listening routers.
C. GLBP allows for a maximum of four MAC addresses per group.
D. HSRP supports up to 255 groups on the same switch or router.
E. VRRP is a Cisco proprietary protocol.
Answer: C,D
Question No: 8
Which two command sequences must you enter on a pair of switches so that they negotiate an EtherChannel using the Cisco proprietary port-aggregation protocol? (Choose two.)

B. channel-protocol pagp channel-group 1 mode auto
C. channel-protocol lacp channel-group 1 mode active
D. channel-protocol pagp channel-group 1 mode desirable
E. channel-protocol pagp channel-group 1 mode on
Answer: B,D
Question No: 9
Which two statements about vrrp are true? (Choose Two)
A. Preemption is not supported
B. It support clear text authentication only
C. It uses a shared vip to support default gateway redundancy
D. It requires each device in the group to participate in the same dynamic routing protocol.
E. It can use a single virtual address to provide default gateways redundancy
Answer: D,E
Question No: 10
Which two statements about VRRP advertisements are true? (Choose two)
A. They are sent every three seconds by default.
B. They include VRRP timer information.
C. They are sent from the master router and standby routers.
D. They are sent only from the master router.
E. They include priority information.
Answer: D,E
Explanation: VRRP AdvertisementsThe virtual router master sends VRRP advertisements to other VRRP routers in the same group. The advertisements communicate the priority and state of the virtual router master. The VRRP advertisements are encapsulated in IP
packets and sent to the IP Version 4 multicast address assigned to the VRRP group. The advertisements are sent every second by default; the interval is configurable.
Although the VRRP protocol as per RFC 3768 does not support millisecond timers, Cisco routers allow you to configure millisecond timers. You need to manually configure the millisecond timer values on both the primary and the backup routers. The master advertisement value displayed in the show vrrp command output on the backup routers is always 1 second because the packets on the backup routers do not accept millisecond values.
You must use millisecond timers where absolutely necessary and with careful consideration and testing. Millisecond values work only under favorable circumstances, and you must be aware that the use of the millisecond timer values restricts VRRP operation to Cisco devices only.
Question No: 11
