Cisco CCNP Enterprise 350-401 Questions & Answers

• Question 261:

  An engineer reviews a router's logs and discovers the following entry. What is the event's logging severity level?

  Router# *Jan 01 38:24:04.401: %LINK-3-UPDOWN: Interface GigabitEthernet0/1, changed state to up

  A. notification

  B. error

  C. informational

  D. warning

  Correct Answer: B

  Syslog levels are listed below:

  

  Number 3 in %LINK-3-UPDOWN is the severity level of this message so in this case it is errors.

• Question 262:

  Which feature is supported by EIGRP but is not supported by OSPF?

  A. equal-cost load balancing

  B. route filtering

  C. unequal-cost load balancing

  D. route summarization

  Correct Answer: C

  EIGRP support unequal-cost load balancing via the "variance ..." while OSPF only supports equalcost load balancing.

• Question 263:

  An engineer connects two switches together and notices that the connected interface on one of the switches is in an err-disabled state.

  The engineer then notices that BPDUGuard is enabled on the interface. How would you correct this?

  A. Switch(config)# interface x/x Switch(config-if)# no spanning-tree bpduguard enable Switch(config-if)# shut Switch(config-if)# no shut

  B. PlaceHolder

  C. PlaceHolder

  D. PlaceHolder

  Correct Answer: A

• Question 264:

  opology: RouterA<>>RouterB<<>>RouterC | | |____________________________| (GRE Tunnel: R-A to R-C)

  Router A send packet to Router C with MTU 1500 using GRE Tunnel. What happens to the packet ?

  A. Router-C will drop the packet

  B. Router-C will de-fragment the packet

  C. Router-C will receive the packet

  D. Router-B will forward the packet

  Correct Answer: C

• Question 265:

  How do agent-based versus agentless configuration management tools compare?

  A. Agent-based tools do not require a high-level language interpreter such as Python or Ruby on slave nodes

  B. Agentless tools require no messaging systems bet-veen master and slaves.

  C. Agent-based tools do not require instaltation of additional software packages on the slave nodes

  D. Agentless tools use proxy nodes to interface with slave nodes

  Correct Answer: A

• Question 266:

  Refer to the exhibit. An engineer must ensure that all traffic entering AS 200 from AS 100 chooses Link 2 as an entry point. Assume tliat all BGP neighbor relationships have been formed and that the attributes have not been changed on any of the routers. Which configuration accomplishes this task?

  

  A. R4(config)#route-map PREPEND permit 10 R4(config-route-map)#set as-path prepend 200 200 200 R4(config)#router bgp 200 R4(conflg-router)#neighbor 10.2.2.2 route-map PREPEND out

  B. R3(config)#route-map PREPEND permit 10 R3(config-route-map)#set as-path prepend 200 200 200 R3(config)#router bgp 200 R3(conflg-router)#neighbor 10.1.1.1 route-map PREPEND out

  C. R4(config)#route-map PREPEND permit 10 R4(config-route-map)#set as-path prepend 100 100 100 R4(config)#router bgp 200 R4(config-router)#neighbor 10.2.2.2 route-map PREPEND in

  D. R3(config)#route-map PREPEND permit 10 R3(config-route-map)#set as-path prepend 100 100 100 R3(config)#router bgp 200 R3(config-router)#neighbor 10.2.2.2 route-map PREPEND in

  Correct Answer: B

• Question 267:

  Which two sources cause interference for Wi-Fi networks? (Choose two).

  A. mirrored wall

  B. 900MHz baby monitor

  C. fish tank

  D. DECT 6.0 cordless

  E. Incandesent lights

  Correct Answer: AC

  Windows can actually block your WiFi signal. How? Because the signals will be reflected by the glass. Some new windows have transparent films that can block certain wave types, and this can make it harder for your WiFi signal to pass

  through.

  Tinted glass is another problem for the same reasons. They sometimes contain metallic films that can completely block out your signal. Mirrors, like windows, can reflect your signal. They`re also a source of electromagnetic interference

  because of their metal backings.

  Reference: https://dis-dot-dat.net/what-materials-can-block-a-wifi-signal/

  An incandescent light bulb, incandescent lamp or incandescent light globe is an electric light with a wire filament heated until it glows. WiFi operates in the gigahertz microwave band. The FCC has strict regulations on RFI (radio frequency

  interference) from all sorts of things, including light bulbs -> Incandesent lights do not interfere Wi-Fi networks.

  Note:

  +

  Many baby monitors operate at 900MHz and won`t interfere with Wi-Fi, which uses the 2.4GHz band.

  +

  DECT cordless phone 6.0 is designed to eliminate wifi interference by operating on a different frequency. There is essentially no such thing as DECT wifi interference.

• Question 268:

  Which deployment option of Cisco NQFW provides scalability?

  A. clustering

  B. Inline tap

  C. high availability

  D. tap

  Correct Answer: C

• Question 269:

  Refer to the exhibit.

  

  An engineer must ensure that all traffic entering AS 200 form AS 100 chooses link 2 as an entry point. Assume that all BGP neighbor relationship have been formed and that attributes have not been changed on any of the router. Which configuration accomplishes this task?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: B

• Question 270:

  An engineer is configuring GigabitEthernet1/0/0 for VRRP. When the router has the highest priority in group 5, it must assume the master role.

  Which command set should the engineer add to the configuration to accomplish this task?

  interface GigabitEthernet1/0/0 description To IDF A 38-70-774-10 ip address 172.16.13.2 255.255.255.0

  A. standby 5 ip 172.16.13.254 standby 5 priority 100 standby 5 track 1 decrement 10

  B. standby 5 ip 172.16.13.254 standby 5 priority 100 standby 5 preempt

  C. vrrp 5 ip 172.16.13.254 vrrp 5 priority 100

  D. vrrp 5 ip 172.16.13.254 255.255.255.0 vrrp 5 track 1 decrement 10 vrrp 5 preempt

  Correct Answer: C

  Preempt is by default enabled on VRRP.
