You receive an alarm that your Junos device is experiencing problems regarding temperature. Which two commands would you use to investigate this problem？（）

dar did not receive a target echo on its last two scans due to the weather．What should you expect under these circumstances ________．

A.The ARPA will generate data as if the target was still being tracked by radar

B.The ARPA will give an audible and/or visual lost target alarm

C.The ARPA will generate data based on sea return echoes from the vicinity where the target was lost

D.The ARPA has lost all memory of the target and must recompute the target data

Which of the following reasons might lead to the MEG LOC alarm in the PTN equipment？ ()

A.The basic configurations of ARP and MAC are faulty.

B.The optical module passing through two MEPs is unable to normally receive or transmit the optical signals.

C.The client equipment has no service signals.

D.The related MEG parameters configured in the equipment at two ends are inconsistent.

The brain is a seemingly endless library, whose shelves house our most precious memories as well as our lifetime’s knowledge. But is there a point where it reaches capacity. The answer is no, because brains are more sophisticated than that. Instead of just crowding in, old information is sometimes pushed out of the brain for new memories to form. Precious behavioral studies have shown that learning new information can lead to forgetting. But in a new study, researchers demonstrated for the first time how this effect occurs in the brain. In daily life, forgetting actually has clear advantages. Imagine, for instance, that just lost your bank card. The new card you receive will come with a new personal identification number(PIN). Each time you remember the new PIN, you gradually forget the old one. This process improves access to the relevant information, without old memories interfering. And most of us may sometimes feel the frustration of having old memories interfere with new, relevant memories. Consider trying to remember where you parked your car in the same car park you were at a week earlier. This type of memory (where you are trying to remember new, but similar information) is particularly vulnerable to interference. When we acquire new information, the main automatically tries to incorporate(合并) it within existing information by forming associations. And when we retrieve(检索) information, both the desired and associated but irrelevant information is recalled. The majority of previous research has focused on how we learn and remember new information. But current studies are beginning to place greater emphasis on the conditions under which we forget, and its importance begins to be more appreciated. A very small number of people are able to remember almost every detail of their life. While it may sound like an advantage to many, people with this rare condition often find their unusual ability burdensome. In a sense, forgetting is our brain’s way of sorting memories, so the most relevant memories are ready for retrieval. Normal forgetting may even be a safety mechanism to ensure our brain doesn’t become too full. What does the passage say about forgetting？

A、It can enlarge our brain capacity.

B、It helps get rid of negative memories.

C、It is a way of organizing our memories.

D、It should not cause any alarm in any way.

A. show hadrware alarms

B. show system alarms

C. show chassis state

D. file list alarm

lf.

A、going off

B、going on

C、going out

D、going up

At the earliest indication of fire aboard your vessel, you must FIRST ______.

A.locate the fire

B.determine which type of fire is burning

C.sound the alarm

D.fight the fire

t？()

A.To display current alarm of device correctly, the device needs to report current alarm to EMS actively. Therefore, necessary configuration for the device to actively report alarms must be correctly set.

B. Protection switching event alarm occurs at the instant when protection group switching happens, so it is not durative alarm. Therefore, after the alarm occurs, it is immediately saved in locking alarm. You can check it only in the locking alarms.

C. If EMS server timezone is different from PTN device timezone, alarm occurrence time on PTN device will be different from that on EMS. Therefore, during commissioning of PTN, you should set PTN timezone to be consistent with EMS timezone, usually local timezone.

D. None of the above

myself.

A、going off

B、going on

C、going out

D、going up

he same signal on the general alarm, you should ______.

A.start the fire pump

B.go to your man overboard station

C.go to your lifeboat station

D.stand by for collision
